Because of that belief, some physicians buy a property late in the year, place it in service in Q4, and simply log 100 hours before December 31.

On paper, that sounds straightforward.

The problem is that many of the hours people log do not actually count under the tax rules.

During IRS audits, hours related to investment analysis, pre-purchase due diligence, and other non-operational activities are frequently removed from the material participation calculation.

If those hours are excluded, the loss can be reclassified as passive — meaning it no longer offsets physician W-2 income.

So if you’re planning to implement the short-term rental strategy, it’s important to understand what hours actually count as material participation.

How Does the “Short-Term Rental Loophole” Work?

By default, rental activities are considered passive under Internal Revenue Code §469.

The problem?

Passive losses generally cannot offset nonpassive income, such as W-2 physician income.

However, there is a narrow path out of the “rental activity” category - and that exception is what makes the short-term rental loophole possible.

If the average period of customer stay is 7 days or less, the activity is not treated as a “rental activity” for §469 purposes under Temp. Reg. §1.469-1T(e)(3)(ii).

In other words, by structuring the property as a short-term rental, the activity can fall outside the default rental classification.

But that alone is not enough.

Even if the activity is not treated as a rental activity, it is still passive unless you materially participate.

To treat the income or loss as nonpassive, you must still satisfy one of the material participation tests under IRC §469(h)(1) and Temp. Reg. §1.469-5T.

That’s the part many people underestimate.

Why Doctors Try the Q4 Strategy

This strategy is widely discussed in physician real estate forums and podcasts.

A common playbook looks like this:

• Buy property in Q3

• Renovate and prepare it

• Begin renting in November or December

• Self-manage the property

• Log more than 100 hours

• Claim a nonpassive loss to offset physician W-2 income

High-income physicians are particularly drawn to this strategy because a single STR loss can potentially offset a large amount of W-2 income.

One of the seven material participation tests says participation is material if:

• You participate more than 100 hours during the year, and

• No one else participates more than you

On paper, that sounds achievable.

In practice, if the property only operates for a few weeks in Q4, it can be difficult to accumulate 100+ hours of genuine operational work — especially if there are only a handful of bookings.

Where Audits Often Go Sideways

When operational hours are limited, people often start including activities such as:

• Traveling to look at properties

• Market research

• Financial modeling

• ROI projections

• Interviewing property managers

• Reviewing underwriting

• Feasibility analysis

Then all of that time gets logged as “material participation.”

This is exactly where audits tend to go sideways.

What the Tax Law Actually Says

IRC §469(h)(1) defines material participation as involvement in the operations of the activity that is regular, continuous, and substantial.

Temp. Reg. §1.469-5T measures participation based on your involvement during the taxable year and sets out the specific material participation tests.

Two elements are critical:

You must

• own an interest in the activity, and

• be involved in its operations.

If you do not yet own the property (or otherwise have an ownership interest in the activity), there is generally no activity in which you can materially participate.

Investor Activities Do Not Count

Even after you own the property, not all hours count.

Temp. Reg. §1.469-5T(f)(2) states that work performed in an individual’s capacity as an investor does not count toward material participation unless the individual is directly involved in the day-to-day management or operations of the activity.

The regulation identifies investor-type activities such as:

• Studying or reviewing financial statements or operational reports

• Preparing financial summaries, projections, or analyses for your own use

• Monitoring the activity’s finances or operations in a nonmanagerial capacity

Time spent on these tasks is generally excluded when determining material participation unless the work is directly tied to operational management.

Why Pre-Acquisition Hours Usually Don’t Count

This framework is especially important for short-term rentals.

Many doctors spend substantial time analyzing deals before purchasing a property (that’s how we are built).

However, most of that time is both:

• pre-ownership, and

• investor-level due diligence.

Under the regulations, those hours typically do not count toward material participation.

For example:

• Traveling to Hawaii to tour potential STR properties before closing

  • This is generally investment due diligence and occurs before you own any interest in the activity. These hours typically do not count.

• Building a long-term financial model before acquiring the property

  • Preparing projections or ROI analyses for your own decision-making is investor activity. If done before acquisition, it is also pre-ownership. These hours usually do not count.

• Interviewing property managers before purchasing the property

  • Evaluating managers before acquisition is part of the investment decision process — not the operation of an activity you already own. These hours typically do not count.

In short, material participation measures involvement in the actual conduct and operation of the activity during the period you own it — not the time spent deciding whether to invest.

Why This Matters in an IRS Audit

If you are audited and your 100-hour test is supported primarily by:

• pre-ownership due diligence, or

• investor-type activities,

the IRS can reclassify the loss as passive.

For a high-income doctor using a large STR loss to offset W-2 wages, that adjustment can be very costly, potentially including additional tax, penalties and interest.

That can be a very expense mistake. Ouch!

How To Implement This Strategy Correctly

If you want short-term rental losses to be treated as nonpassive, the structure and documentation must align with §469 and the regulations.

First, confirm the activity actually qualifies as a short-term rental.

• The average period of customer stay must be 7 days or less.

Second, track operational hours only after you own the property.

• Hours before you have an ownership interest are generally not counted as participation.

Third, focus your time log on real operational management activities such as:

• Guest communication and messaging

• Cleaning and turnover coordination

• Vendor scheduling and oversight

• Repairs and maintenance management

• Pricing adjustments and listing optimization

• Active oversight of ongoing operations

These activities more clearly support material participation in the operations of the activity.

Fourth, if you intend to rely on the 100-hour test, make sure you truly meet it.

• You must participate more than 100 hours and no one else — including cleaners, property managers, co-hosts, or contractors — participates more than you.

Finally, plan earlier in the year whenever possible.

• Trying to start everything in Q4 often leaves too little time to accumulate legitimate operational hours.

Final Thought

The short-term rental strategy can work.

But it must be implemented within the framework of IRC §469 and the regulations.

Material participation is about operating a business you own — not about analyzing a deal before you buy it or logging investor activities as if they were operations.

You are making a meaningful capital investment.

Align the structure with the tax rules first.

Then execute carefully — and track your hours accurately and timely.

You own:

• A professional corporation (or PLLC) for your dental practice

• An LLC for your dental building.

Clean. Logical. Standard.

Then someone says:

“Hey… elect S-corp for the building too. Save on taxes.”

And you think:

“Of course. S-corp is always better.”

Pause.

This is where even very sophisticated dentists — and their advisors — get it wrong.

The Rule Most People Forget

When it comes to real estate, the default is usually:

• Disregarded entity (single-member LLC), or

• Partnership (multi-member LLC)

Not S-corporation.

Why?

Because real estate is not just about saving tax today.

It’s about flexibility tomorrow.

And S-corps quietly destroy that flexibility.

The Vasectomy Analogy

Electing S-corp for real estate is like a vasectomy.

Seems simple.
Sounds efficient.

But reversing it later?

Painful. Costly. Sometimes not feasible.

What Actually Changes with a S election

Before:

“I own the building.”

After:

“My S-corp owns the building.”

That sounds subtle.

It’s not.

Because once you make the S election, you’ve stepped into corporate tax rules — Subchapter S.

And those rules are unforgiving when you try to move that property later.

The Trap: Getting the Building OUT

Meet Dr. Crown.

• Bought building: $500K

• Value today: $2.5M

He’s retiring and wants to:

• Move it into a trust

• Transfer to another entity

• Or just hold it personally

All reasonable.

But here’s the problem:

He can’t take it out without triggering tax.

The Tax Bomb — IRC §311(b)

If an S-corp distributes appreciated property like his dental building:

The IRS treats it as if the corporation SOLD the property at fair market value.

What???

Even if:

• No cash changes hands

• You still own 100%

• Nothing economically changed

Tax law says:

“Sale.”

Result:

• Gain = $2.5M – $500k = $2M

• That gain flows to you under IRC §1366

• You pay tax on $2M

Just to move your own building.

That’s the trap.

“I’ll just Hold It Until Death” Strategy

Great instinct.

Under IRC §1014:

• Assets get stepped up to fair market value at death

• Built-in gain disappears

This is one of the most tax-payer friendly rules in the entire Code.

But inside an S-corp

It breaks.

The Hidden Problem at Death

At death:

• Your S Corp stock gets a step-up

• The building inside the S-corp does NOT

So If Dr. Crown’s heirs sell the dental building:

• Gain is still based on $500k basis

• Same $2M gain shows up

If they try to distribute it?

→ IRC §311(b) kicks in

→ The distribution is treated as a sale

→ Same tax hit

The gain isn’t eliminated.

It is trapped.

Why Partnerships Win

Most real estate uses partnerships for one big reason:

Flexibility.

With a partnership:

• You can often take cash or property out without triggering tax

With an S-corp:

• Taking property out can trigger a taxable “sale”

That’s the difference.

One gives you flexibility.

The other can create a tax bill just for moving your own asset.

When it comes to real estate:

Partnerships win.

When an S-corp Might Still be Okay

There are limited cases:

• Short-term hold (you plan to sell soon anyway)

• Minimal appreciation expected

• You’re already stuck in it and unwinding is worse

But notice the pattern:

These are exceptions.

Not the strategy.

The Clean Structure

For most dentists:

Practice:

• Professional Corporation or Professional LLC

• Taxed as S-corp (for income planning)

Building:

• LLC

• Taxed as a disregarded entity (single owner) or partnership (multiple owners)

Why this works:

• Income planning → S-corp

• Asset flexibility → LLC

Separate. Optimized. Intentional.

Final Thought

S-corps are powerful.

But not universal.

For operating businesses?

Often great.

For appreciating real estate?

They can create a major tax trap.

And I’ve seen that mistake cost:

Hundreds of thousands in unnecessary tax.

All from one election…

That sounded like a “no-brainer.”

Your CPA tells you:

“Buy a G-Wagon. You deserve it, Doc. Even better—you can write it off.”

You hear:

“Free car paid for by my practice. Nice!”

So you spend a cool $150k…
Take $150k of bonus depreciation…
And move on with life.

Too busy to track mileage.
No mileage log.
No tracking.
No system.

Then the IRS shows up.

The Moment Everything Changes

Most doctors think:

“If it’s business-related, I can deduct it.”

That’s only half the formula.

Here’s the real rule:

Step 1 → Is it deductible?
→ IRC §162 (ordinary and necessary business expense?)

Step 2 → Can you prove it?
→ IRC §274(d) (strict substantiation for listed property like vehicles under IRC §280F)

If you miss Step 2…
Step 1 doesn’t matter.

No proof = no deduction.
That’s written into the Code.

The IRS Doesn’t Assume. They Ask.

The IRS is not asking:

“Does this look like a business expense?”

They’re asking:

“Show me.”

Passenger vehicles and SUVs are “listed property” under IRC §280F(d)(4), because they’re historically prone to abuse - therefore subject to stricter rules.

So IRC §274(d) requires specific proof of:

• Amount (miles or expense)

• Date and use (when and where you drove)

• Business purpose (why you drove there)

This must be supported by “adequate records”:

• Mileage logs

• Diaries or trip sheets

• Contemporaneous tracking supported by receipts or calendars

No adequate records?
No Deduction.

“But What About the Cohan Rule?”

Yes - Cohan v. Commissioner, 39 F.2d 540 (2d Cir. 1930), allows estimated deductions when expenses were incurred but the exact amount is uncertain.

Sounds helpful.

It’s not—for vehicles.

Congress shut that down with IRC §274(d).

For listed property (like cars):
Estimates don’t count.
You must substantiate.

Translation:

“I drove a lot for work”
≠ deductible

No mileage log = no vehicle deduction.

How a $150,000 Deduction Becomes $0

Dr. G-Wagon thought:

“I used the car for work.”

The IRS said:

“Prove it.”

He couldn’t show:

• Total miles driven

• Business vs. personal miles

• Dates and locations of trips

• Business purpose for each business trip

Result:

The $150,000 bonus depreciation deduction on the listed-property vehicle — claimed under IRC §168 (including §168(k) bonus) — was disallowed under §274(d).

$150,000 deduction → $0
Plus penalties
Plus interest

The Real Lesson

Don’t ask:

“Can I write this off?”

Ask:

“How will I prove this to the IRS?”

Because in tax:
You are not innocent until proven compliant.

Dr. Taxtor’s Prescription

If you’re taking large vehicle deductions:
Build the system BEFORE the deduction.

• Track mileage (app or log, with total and business miles)

• Record entries contemporaneously, or as close in time as possible

• Document business purpose for each trip

• Track total miles vs. business miles annually

Substantiation isn’t paperwork.
It’s protection.

Final Thought

The deduction is not the strategy.
The proof is.

“I love Hawaii. Can I just go there, watch some on-demand CME, and write off the trip as a business expense?”

At first glance, it sounds like a brilliant idea.

Unfortunately, the tax law usually does not allow this. Watching CME from Waikiki Beach does not, by itself, turn your vacation into a deductible business trip under the tax rules for travel expenses.

But this scenario is actually a great way to understand one of the most important tax concepts for physicians who run their own practice: Internal Revenue Code §162.

The Backbone of Business Deductions: IRC §162

IRC §162(a) is the core rule that determines whether a business expense is deductible.

It allows a deduction for:

“all the ordinary and necessary expenses paid or incurred during the taxable year in carrying on any trade or business.”

Travel expenses “while away from home in the pursuit of a trade or business” are specifically mentioned in IRC §162(a)(2).

So when we analyze whether a trip is deductible, we need to look closely at two key concepts embedded in this rule:

• Ordinary

• Necessary

What Does “Ordinary” Mean?

The Internal Revenue Code does not define the word ordinary, so the courts stepped in to explain it.

An ordinary expense is one that is normal, usual, or customary in the type of business involved. This principle was explained in the Supreme Court case, Deputy v. Du Pont, 308 US.

In plain English, an ordinary expense is one that is common and accepted in your profession.

For doctors, travel often falls into this category. Doctors routinely travel to:

• medical conferences

• training courses

• professional meetings

• networking events

So travel itself is usually not the problem when it comes to deductibility. It is generally easy to argue that travel is ordinary in the medical profession.

What Does “Necessary” Mean?

The word necessary is also not defined directly in the Code. Courts have interpreted it to mean that an expense must be appropriate and helpful to the business, most notably in the Supreme Court case, Welch v. Helvering, 290 U.S 111. It does not have to be absolutely essential or indispensable.

Continuing medical education clearly helps physicians maintain and improve their professional skills. For an actively practicing doctor, CME that maintains existing skills is typically a necessary business expense.

So far, so good.

Travel is often ordinary, and CME is usually necessary.

The trouble comes when we mix travel with personal vacation.

The Primary Purpose Test for Travel

Even if an expense is ordinary and necessary, that does not automatically mean travel is deductible.

The Treasury Regulations interpreting §162 introduce another important concept for trips that contain both business and personal elements like traveling to Hawaii to take a on-demand CME course: the primary purpose test.

The key question becomes:

“What was the primary purpose of the trip?”

If the trip is primarily for business, then:

• Transportation to and from the destination is generally deductible

• Lodging and meals may be deductible for the business days.

If the trip is primarily personal, such as a vacation, then:

• Transportation to and from the destination is not deductible

• Personal meals and lodging are generally not deductible

However, specific business expenses incurred while you are there may still be deductible - for example, the fee for the on-demand CME course.

In determining whether the trip is primarily for business or personal, a facts-and-circumstances test is used. This is somewhat analogous to “clinical correlation recommended” in the radiology report. On a side note, as an ER doc, this comment used to annoy me at times. Arrrr.

So, the practical question become,

“How much time you spend on business versus vacation?”

Applying the Rules to the Hawaii CME Example

Now let’s return to Hawaii.

Suppose a physician flies to Hawaii and watches on-demand CME videos from the hotel room.

The CME course fee itself is typically an ordinary and necessary business expense, assuming it maintains or improves skills in the physician’s current specialty.

But the key questions for the deductibility of the travel expenses are:

• Did you need to travel to Hawaii to obtain this education?

• Was the trip primarily for business, or primarily a vacation?

Because the CME is on-demand, you could have watched it from:

• your home

• your office

• a local coffee shop

In that situation, the travel is not necessary for the education. It is simply the location where you chose to watch the material.

Putting this all together, the IRS would almost certainly view the primary purpose of the Hawaii trip as personal vacation, not business.

If that is the case, the following expenses would not be deductible:

• airfare to Hawaii

• hotel lodging

• most meals and personal incidentals during the trip

However, the CME course fee itself may still be deductible as a professional education expense, separate from the travel.

Final Thoughts

Watching CME during a vacation does not automatically turn the vacation into a business trip.

Under IRC §162, the key issue is the primary purpose of the travel. If the trip is primarily personal, the travel costs are not deductible - even if some education happens while you are there.

At most, you may be able to deduct the CME fee itself.

This is why tax planning matters.

Many physicians assume that adding a little business activity to a vacation can turn the entire trip into a tax write-off. The law simply does not work that way.

Understanding the “ordinary and necessary” standard under IRC §162, and how the primary purpose test applies to travel, is essential for doctors who run their own business.

When you understand how these rules actually work, you can structure travel and education in a way that both advances your career and stands up to IRS scrutiny - without unpleasant surprises later.

It saves time. It saves money. And for things like LLC operating agreements - documents that used to cost thousands - it feels like a no-brainer.

But here’s the part most people miss.

AI may not understand your true intent.

And when you rely on it without a guardrail, you can walk straight into a tax disaster.

Meet Dr. Bicep

Dr. Bicep is an orthopedic hand surgeon in Las Vegas.

Talented, driven, smart, and finally ready to go independent.

He leaves his W-2 job and launches his own surgical practice. Like many physicians stepping into entrepreneurship, he hears the same advice from colleagues:

“You should elect S corp. It’s the best.”

It sounds right. His friends are successful entrepreneur surgeons. Why question it?

And more importantly - why spend money on an attorney when AI can draft an operating agreement in seconds?

So he does exactly that.

He uses AI to generate his PLLC operating agreement.
Files Form 2553.
Everything looks clean. Professional. Legit.

Business takes off. Revenue is strong. Confidence is high.

The “Tax Strategy” Phase

With cash flowing in, Dr. Bicep starts implementing what he believes are smart tax strategies.

• He buys a fully loaded G-Wagon for a cool $250K and claims 100% business use with bonus depreciation - without keeping a mileage log.

• He purchases a $2M condo at the Waldorf Astoria Residences on the Las Vegas Strip and claims an 800 sq ft home office in a 1,500 sq ft unit.

• He writes off eight international trips as “business travel.”

From his perspective, it all makes sense. He learned it from TaxTube. His friends are doing similar things.

Why not take advantage of the tax code?

The Audit

The IRS steps in.

And one by one, the deductions collapse.

• G-Wagon deduction → disallowed. No substantiation. And 100% business use? Not credible.

• Home office → denied. Not exclusive use. Not reasonable.

• International travel expenses → rejected. Personal trips dressed up as business.

Painful - but predictable if you understand the tax rules.

Then something worse happens.

The Line That Changes Everything

The IRS agent reviews his PLLC’s operating agreement.

And says:

“Your S corporation election is invalid.”

Mic drop.

Because up until this moment, Dr. Bicep believed he was operating as an S corporation.

He wasn’t.

Why This Is Devastating

An S corporation is a pass-through entity. Income flows through to the owner and is taxed once.

A C corporation is not.

It is taxed at the corporate level, and then again when profits are distributed.

That’s double taxation.

Now, Dr. Bicep is facing:

• Corporate-level tax on his income

• Dividend tax when he takes money out

• Loss of the payroll tax advantages he expected from an S corp

All because of one document he never questioned.

What Actually Went Wrong

The rules for S corporation elections are governed by IRC §1361.

S status is not automatic. It’s conditional.

You only qualify if you meet every requirement.

One of the most misunderstood rules is this:

• The corporation can only have one class of stock.

The Hidden Trap: One Class of Stock

This does not mean “only common stock” or “one certificate.”

Under IRC §1361(b)(1)(D) and Treas. Reg. §1.1361-1(l), it means:

All shareholders must have identical rights to distributions and liquidation proceeds.

In simple terms:

Ownership percentage must match economic rights.

• If you own 30%, you receive 30%. Every time.

What AI Did

The operating agreement looked polished. Even sophisticated.

But it was written like a partnership agreement.

It included:

• Special allocations of income and loss

• Non-pro-rata (uneven) distributions

• Different liquidation rights

These provisions are completely normal in partnerships.

But they are fatal for S corporations.

Because they create unequal economic rights.

And once that happens, you no longer have one class of stock.

Why This Kills Dr. Bicep’s S Election

Under IRC §1361(b)(1)(D), having more than one class of stock disqualifies the entity from being an S corporation.

There is no gray area here.

No “close enough.”
No “we’ll fix it later.”

If your governing document allows unequal economic rights, your S election is invalid.

In Dr. Bicep’s case, it was invalid from day one.

The Most Dangerous Part

Dr. Bicep didn’t do anything intentionally wrong.

He wasn’t hiding income.
He simply didn’t know.

AI gave him something that sounded correct - but it violated a core requirement of the tax code.

That’s the risk.

Can You Fix It?

Sometimes.
But it’s not easy.

You may qualify for relief under IRC §1362(f) if the IRS agrees the issue was inadvertent.

There are also limited streamlined fixes under Rev. Proc. 2022-19.

If those don’t apply, you’re left with requesting a Private Letter Ruling (PLR)

PLR typically means:

• IRS user fee of $40,000+ (omg!)

• Significant professional fees

• No guarantee of approval

And if relief is denied, you may be stuck as a C corporation for years.

The Takeaway

AI is powerful.

But it may not fully understand your intent. And it definitely does not care about the consequences.

It generates language - not outcomes.

Final Thought

Use AI to draft.
But use a professional to verify.

Because one paragraph, just one, that violates IRC § 1361 can quietly destroy your S election and cost you six figures before you even realize it.

A week later:

“Doctor… this changed my life. This is for you.”

She hands you the keys.
A $500,000 Ferrari SF90 Stradale.

Wow. Unbelievable.

Before you celebrate, pause.

Do you report:

• just the $20,000 of surgical fee …

• or an additional $500,000 of income for the Ferrari?

Why This Gets Uncomfortable

Because the answer is:

In a professional setting like this, it’s almost always income.
Only in very narrow, fact-specific situations could you argue “gift.”

The Tax Framework You Need

Here’s a mental model:

IRC §61 → gross income includes everything you receive, unless income a specific exclusion applies.

IRC §102 → gifts are excluded - but only if they truly qualify as “gifts”.

So the entire question becomes:

Was the Ferrari a true “gift” under §102…
or compensation under §61?

The problem?

The tax code never clearly defines “gift”.
So we go to the Supreme Court.

The Supreme Court Standard (Commissioner v. Duberstein)

The Duberstein Court says:

A “gift” must come from:

• “detached and disinterested generosity… out of affection, respect, admiration, charity or similar impulses”

And importantly:

• You don’t just take someone’s word for it.

• You look at the objective facts.

What “Gift” Really Means

A true gift is:

“Something for nothing” - no quid pro quo

• No exchange

• No expectation

• Not “because you did this for me”

The moment it becomes:

“This is because of what you did…”

… then, it starts to look like income.

Apply it to Dr. Nip Tuck

Now plug in the facts:

• A plastic surgeon.

• life‑changing cosmetic surgery.

• Paid $20,000

• One week later: a new $500k Ferrari

Ask yourself, objectively:

Does that look like “detached generosity”?
Or a very large “thank‑you payment”?

Why the IRS is Skeptical

In professional relationships - doctor, lawyer, consultant

Transfers are usually not gifts.

They’re:

• bonuses

• tips

• or extra compensation dressed up as generosity

The IRS starts from:

• Default: everything is income under §61.

• §102 is an exception - and interpreted narrowly.

• In a doctor–patient setting, a big transfer right after treatment usually looks like compensation, not detached generosity.

Two Possible outcomes.

Version 1 - Likely IRS Position

“This is for the amazing work you did”

• Professional relationship.

• Transfer immediately after services.

• Directly tied to the outcome

• Motivated by gratitude for the procedure.

Result:

• $20k rhinoplasty fee = income

• $500k Ferrari = additional taxable income

This is compensation, not a §102 gift.

Version 2 - The narrow “Gift” Argument

To even argue gift under §102, you’d need very different facts:

• A genuine, established personal relationship outside the medical context

• No expectation of better service or access

• No connection — explicitly or implicitly — to the procedure

Even then,

Duberstein requires looking at all facts and circumstances.

Calling something a “gift” doesn’t automatically make it one.

The Uncomfortable Truth

A thank‑you note doesn’t save Dr. Nip Tuck.

“I’m forever grateful” can still mean:

“I’m paying you more.”

Also:

“No legal obligation” ≠ “gift”

Voluntary payments can still be taxable income.

What the IRS Actually Focuses On

In practice, the IRS zeroes in on:

• Timing (right after the procedure => strong compensation signal).

• Relationship (professional => not naturally donative).

• Intent (“why was this really given?”).

• Substance (“does it feel like payment?”).

If it walks and talks like compensation…

It’s probably compensation.

Final Takeaway

The IRS doesn’t start neutral.

They start with:

“This is income.”

And you have to provide otherwise.

So in real life, for Dr. Nip Tuck:

• Report the $20,000 fee, and

• Report the $500,000 Ferrari as additional taxable income.

Unless you have very unusual, very clean facts.

Why This Matters

Same transaction.
Two theoretical tax outcomes.

But the difference isn’t what you call it.

It’s the facts, the framing…

… and what was true before the keys changed hands.

You home has appreciated significantly, and you want to convert it into a rental.

Then your tax pro tells you:

“Sell it to your S corporation.
Lock in your $500k home gain exclusion under §121.
Step up the basis to fair market value.
Then depreciate it and create losses.”

It sounds elegant.
It sounds strategic.
It sounds like something only sophisticated investors do.

And that’s exactly what makes it dangerous.

This is the kind of strategy that makes high-income physicians feel like they’re finally “playing the game right.”

But in reality, this is one of the fastest ways to accidentally create a six-figure tax problem.

Meet Dr. Silicon Valley

Dr. Silicon Valley receives a home from his mother as a gift.

• Fair market value: $3,000,000

• Carryover basis from mom (who bought it years ago): $200,000

He and his wife, a realtor, live in the home as their primary residence for five years after receiving it. Now, they are ready to move and are considering converting the property into a rental.

His advisor recommends:

“Sell it to your newly formed S corp for $3 million.”
Lock in your $500k home gain exclusion under §121.
Step up the basis to $3M
Then rent it out, depreciate it and generate losses to offset your physician income since your wife is a real estate professional”

On paper, everything seems to line up.

Step 1 — The “Win” Everyone Focuses On

Let’s start with what’s actually correct.

When Dr. Silicon Valley sells the home:

• Amount realized: $3M

• Adjusted basis (carryover from mom): $200k

• Realized gain: $2.8M

Assume he and his wife qualify for the full $500k home gain exclusion under §121,. That means:

• §121 exclusion = $500,000

• Remaining gain to recognize = $2.3M

Also,

• The S corp’s purchase price, and therefore its starting cost basis, is $3M

• Suppose $500K is allocated to land, which is non-depreciable, and $2.5M is allocated to the building, which is depreciable.

At this point, most people feel like they’ve already won.

You locked in the exclusion.
You stepped up the basis.
You’re about to generate losses from the building depreciation.

Everything looks perfect.

And then the tax code steps in.

Step 2 — The Rule That Quietly Turns This Against You: §1239

This is where the entire strategy starts to unravel.

IRC §1239 says:

• If you sell property to a related party, and that property is depreciable in the buyer’s hands, the gain is not capital gain.

• It becomes ordinary income.

Let that sink in.

You didn’t change the economics.
You didn’t make more money.

The tax code just changed the character of your gain.

And that single change is what creates the damage.

Now apply it here.

After your §121 exclusion, you still have about $2.3M of gain.

Most of that gain is tied to the building —which is depreciable inside the S corporation.

That means roughly $1.9M of your gain is now taxed as ordinary income.

Not at 20% capital gains rate.

But at 37% ordinary income rate.

That difference alone?

• Over $300,000 in additional tax.

Not from a bad investment.
Not from market risk.
Just from how the gain is classified.

This is the kind of rule that almost never shows up in the “strategy pitch.”

Step 3 — The Transaction Must Be Real (Not Just a Paper Sale)

Even if you accept the §1239 related-party sale issue, there is still a bigger problem.

The IRS does not automatically respect this as a real sale just because you drafted documents and changed title.

To achieve the intended result from Step 1 (recognized gain, the use of §121, a new fair market value basis inside the S corp), the transaction must actually be a real sale.

It cannot be a disguised contribution or a circular paper transaction.

A key question from cases like Anschutz Co. v. Commissioner is whether there was a genuine transfer of the benefits and burdens of ownership.

In a bona fide sale:

• The S corp must bear economic risk after the transaction

• The note issued by the S corps must have real and commercial terms, including interest, enforceable payment obligations and meaningful economic substance.

• There must be a genuine transfer of control to the S Corp

• Dr. Sillicon Valley must actually give up benefits and burdens of ownership

If those factors are not present, the IRS can argue that this was never really a sale at all.

Instead, the IRS may say:

“This was simply a contribution of property to the S corp by Dr. Sillicon Valley”

Step 4 — The Nightmare Scenario: It Was Never a Sale

Here’s where things go from bad to worse.

If the IRS determines this wasn’t a real sale…

Everything you thought you accomplished disappears.

• No gain recognition.

• No §121 exclusion.

• No step-up in basis.

Instead, the IRS treats it as a contribution to your S corporation.

Now the property sits inside the S corp with a ~$200k carryover basis.

Your depreciation? Minimal.
Your “strategy”? Gone.

And the worst part?

You may have permanently given up one of the most valuable tax benefits in the entire code—§121—without getting anything meaningful in return.

And by the time you realize it…

It’s too late to fix.

Step 5 — The Mortgage Problem No One Talks About

Now let’s step outside the tax code.

Most homes have a mortgage.
And almost every mortgage contains a due-on-sale clause.

That means, if you transfer the property to your S corp:

• The lender can demand immediate repayment of the full loan balance.

If that happens, you may be forced to:

• Refinance (often at worse terms), or

• Pay off the loan entirely

This is not some obscure technicality.

This is a real-world deal killer.

This isn’t a tax issue anymore.
This is your lender calling the loan, just like Dave Ramsey experienced in his investing career.

Step 6 — The “Workaround” That Creates Another Tax Problem

Some advisors try to work around the due-on-sales problem using a land trust and relying on the Garn–St. Germain Act.

The idea is to structure the transfer into a trust arrangement that does not trigger the due-on-sale clause which requires the shareholder to continue to occupy the property

But there’s a major catch:

If Dr. Silicon Valley continues to occupy the home, the property is still used as a residence.

That creates another tax problem.

At the S corporation level, IRC §280A is triggered. This provision can severely limit or even disallow deductions related to the property due to shareholder personal use.

So now:

• You might have mitigated the mortgage due-on-sale risk,

• But you’ve created a situation where the S corps’s “rental” deductions are heavily disallowed under §280A.

In other words, the “solution” to one problem creates a different problem.

Step 7 — Multi-Layer Complexity Most People Underestimate

This is not a DYI tax strategy.

This strategy touches multiple areas of law all at once:

• §121, the home gain exclusion

• §1239, which recharacterizes gain as ordinary income in related-party sales of depreciable property

• §267, which supplies the related-party rules

• §280A, which can disallow deductions when there is personal use of home.

• Judicial doctrines such as bona fide sale, economic substance

• Mortgage law, especially due-on-sale clauses

• State transfer taxes, and legal fees, and title issues

Every layer has to work perfectly.

If even one fails, the entire structure collapses.

The Real Risk

You thought you were creating tax losses.

Instead, you may have:

• Triggered six-figure ordinary income under §1239

• Lost your $500k §121 exclusion

• Destroyed your depreciation step-up

• Locked the property inside an entity that can’t use §121

• Created a refinancing problem you didn’t plan for

All from a strategy that was supposed to save taxes.

In Dr. Sillicon Valley’s case, the total damage can easily exceed $200,000–$300,000.

Final Thought

If someone presents this “sell your home to an S corp” strategy as:

“Simple”
“Common”
or “A great way to step up basis and create losses”

Pause.

Because this is exactly how costly mistakes start.

This strategy doesn’t fail because it’s aggressive.
It fails because it looks simple.

And when tax rules, legal structure, and real-world constraints all have to align perfectly…
“Almost right” isn’t close.
It’s a completely different outcome.

And in tax, that difference isn’t theoretical.
It shows up as a check you didn’t expect to write.

Then one night, while scrolling through Instagram…

You come across it: a real estate guru.

He is charismatic and convincing.
“Quit medicine in 3–5 years through real estate investing.”

It sounds perfect.

Meet Dr. Burnout

Dr. Burnout is a primary care doctor.

He is smart and hardworking—but completely exhausted by endless in-basket messages and lack of appreciation.

He spends two hours charting after shifts, deals with consultants dumping work on him, and feels constantly undervalued.

The thought of doing this for another 10–15 years feels like staring into an abyss.

He wants a way out. STAT

The Pitch of the Guru

The program only costs $20,000.

The guru tells Dr. Burnout:

“Don’t worry… it’s deductible.”

Now it feels like an easy decision.

He signs up.

He spends two weeks in a bootcamp learning everything about real estate investing.

He feels inspired…

…but he is not quite ready to close on a deal yet.

The Reality Check

Dr. Burnout walks into his CPA’s office.

He places the $20,000 receipt on the table.

“I should get a $20,000 deduction this year, right?”

The CPA pauses.

Then responds:

“Sorry, Doc. This is non-deductible.”

Why This Happens All the Time

This situation is extremely common: a burned-out doc hears a great-sounding pitch about reaching FIRE quickly and pays a large amount for “personalized” coaching.

The confusion about deductibility comes down to one key rule:

The tax law treats learning a new trade or business very differently from improving skills in a trade or business you already carry on.

Under IRC §162 and Treas. Reg. §1.162-5, that distinction is critical.

The Rule (IRC §162 + Treas. Reg. §1.162-5)

Education expenses (including “personalized” coaching) are deductible only if all of the following are true:

• You are already engaged in a trade or business (for example, actively operating a real estate business).

• The education maintains or improves skills in that existing trade or business

• The education does not qualify for a new trade or business.

If the education is part of qualifying you for a new trade or business - even if you never actually switch - it is not deductible.

In addition, seminars and conventions related to investing are generally nondeductible unless you are already in that trade or business. IRC §274(h)(7)

Apply It to Dr. Burnout

Right now, Dr. Burnout is:

• A physician

• Not a real estate professional

• Not operating a real estate business (at best, he is an aspiring investor)

So what is the $20,000 bootcamp actually doing?

It is training him to enter a new field - real estate investing. That is classic “qualifying for a new trade or business” under Treas. Reg. §1.162-5(b)(3), which makes the expense nondeductible.

Result: no deduction under IRC §162 and Treas. Reg. §1.162-5

“What If I Call Myself an Investor?”

Dr. Burnout considers this argument:

“Can I treat this as an investment expense?”

Investment-related expenses are governed by IRC §212.

However, under IRC §67(g), these expenses are currently not deductible for individuals.

Result: Still no deduction.

“Okay… Can I At Least Capitalize It?”

Now Dr. Burnout gets creative.

“What about start-up costs under IRC §195?”

IRC §195 deals with “start-up expenditures” - costs incurred to investigate or create an active trade or business.

Examples include:

• Legal fees

• Market research

• Pre-opening operational costs

If eligible, he can elect to:

• Deduct up to $5,000, and

• Amortize the balance over 180 months once the business begins.

But there is a critical limitation.

To qualify under §195 start-up expenditures, the expense must be the type that would have been deductible under §162 if the business were already up and running.

Here’s where the problem comes in.

Education that qualifies you for a new trade or business is inherently nondeductible under Treas. Reg. §1.162-5(b)(3).

Even if we pretend his real estate business already exists, this initial bootcamp is still “qualifying him” for that new line of work, not improving existing skills.

So it would still not be deductible under §162.

Because it flunks that §162 test, it also fails the §195 requirement.

Result: it cannot be capitalized or amortized either. Just a very expensive lesson.

When Would It Be Deductible?

Here is the key insight.

If Dr. Burnout were already:

• Actively operating a real estate business

• Managing properties on a continuous and regular basis

• Acting with a clear profit motive

Then education that maintains or improves skills in that existing business could potentially be deductible under IRC §162 and Treas. Reg. §1.162-5.

The key is this:

He must already be in the business.

Only then does the education shift from “qualifying for a new trade or business” to “improving skills within an existing one.”

Final Thought

The guru promised Dr. Burnout:

“You can make money quickly and write off the $20k coaching fee”.

The IRS responds:

“Not so fast.”

Before assuming an education expenses are deductible, ask one simple question:

“Am I already in this business and improving my skills - or am I trying to enter it”?

Because the tax outcome changes completely depending on the answer.

A patient comes in with shortness of breath.
CT scan confirms a pulmonary embolism (a blood clot in the lung).

You quickly think about bleeding risk, kidney function, contraindications.

But at a high level, the logic is simple:

• There’s a clot → you thin the blood.

Treatment?

• Blood thinner.

Done. Easy Peasy.

Even a medical assistant can follow that reasoning.

So Why Doesn’t Tax Work Like This?

As both a physician and a tax professional, I’ve realized something:

In tax…

We generally can’t just say:

“I bought something useful → therefore I can write it off.”

Meet Dr. Nip Tuck

Dr. Nip Tuck is a successful Beverly Hills plastic surgeon.
Celebrity clientele
Luxury lifestyle.
Brand-conscious.

One day, he walks into his tax advisor’s office and says:

“Hey… I just bought a Ferrari.
Can I write it off?”

This is where things get complicated.

Because in tax…

There is rarely an answer as simple as the “blood thinner” answer.

Step One: What World Is Dr. Nip Tuck In?

Before deductions even come into play, you have to classify the activity he is engaged in as a plastic surgeon.

There are four basic “worlds” of activity in the tax code:

• Trade or business activity (IRC §162).

• Investment/income‑production activity (IRC §212)

• Hobby/not‑for‑profit activity (IRC §183)

• Personal activity (IRC §262)

So the real question is not:
“Is the Ferrari deductible?”

It’s:
“What activity world is Dr. Nip Tuck operating in?”

Step Two: Is This Actually a Business?

Dr. Nip Tuck needs to be in the §162 “trade or business” world to even argue for a Ferrari write‑off.

So how do we determine that?

We apply the Supreme Court’s standard from Commissioner v. Groetzinger:

• Is he operating with continuity and regularity?

• Is his primary purpose income or profit?

If not → no §162 trade or business.

Game over.
No business deduction.

Step Three: Is It Ordinary and Necessary?

Let’s say Dr. Nip Tuck clearly passes the trade‑or‑business test.

To deduct a business expense, §162 says the expense must be “ordinary and necessary.”

What does that mean in plain English?

From Welch v. Helvering and later cases:

• Ordinary = common or usual in that line of work

• Necessary = appropriate and helpful (not necessarily essential)

Now the real question becomes:

“Is owning a Ferrari common and appropriate for how Dr. Nip Tuck runs his practice?

For most doctors… no.

But for a Beverly Hills plastic surgeon whose whole brand is ultra‑luxury, VIP service, and high‑end image?

Now you at least have an argument that it supports the business brand.

Still not a guarantee.

The IRS (or a court) can still say:

“This looks “too personal” or “not reasonable for this business.”

Step Four: The Tax Code That Can Botch Dr. Nip Tuck’s Write‑Off Plan

Let’s say Dr. Nip Tuck clears all of that.

• He has a real business.

• The Ferrari genuinely supports his brand.

• It’s arguably ordinary and necessary in his specific niche.

He’s ready to write it off using bonus depreciation under §168(k).

Right?

Not so fast.

Enter §280F - the infamous “luxury auto” limitation rules.

Even if everything else works, §280F puts hard dollar caps on how much depreciation (including bonus) he can claim on a passenger car like a Ferrari.

Think roughly $60k-$70K total over several years.

Not even close to a full write-off on a $700K supercar.

Change One Fact, Change the Outcome

Now Dr. Nip Tuck makes a different move.

Instead of a Ferrari…

He buys a Bentley Bentayga with a gross vehicle weight rating (GVWR) over 6,000 pounds.

Now the rules shift:

• Vehicles over 6,000lb are generally not treated as “passenger automobiles” under §280F, so the luxury auto caps may not apply.

• The Bentayga may now qualify for 100% bonus depreciation under §168(k) (federally).

But then…

California steps in.

California does not conform to federal bonus depreciation under §168(k).

So:

• Federal return → potentially 100% deduction in Year 1

• California return → deduction spread over multiple years (no bonus allowed).

Same car.
Same purpose.
Same business.

Completely different outcome - just because of federal vs. state rules.

And Dr. Nip Tuck Is Still Not Done

Even if everything above checks out…

There are still more limitations:

• §469 Passive activity rules

• §465 At‑risk rules

Let’s say Dr. Nip Tuck takes a long sabbatical and stops materially participating in his plastic surgery practice.

Now, his activity may be considered passive.

Result?

The losses from that Bentayga become passive losses—
only usable against passive income, not his active surgical income.

But we’re still not done.

Enter §465.

Now the question becomes:

How much money is he actually at risk of losing?

If his loss exceeds his at-risk amount, the excess is suspended until:

• He puts more money at risk, or

• He sells/disposes of the activity

At this point, Dr. Nip Tuck is thinking:

“This is way more complicated than I expected.”

Exactly.

Why Tax Feels So Frustrating

In medicine:
A high‑level answer is often good enough.

In tax:
A high‑level answer is often wrong.

Because tax is not a one‑step system.

It’s a sequence that must be followed precisely:

1. Classify the activity (business, investment, hobby, personal)

2. Determine whether the expense is ordinary and necessary.

3. Apply the relevant Code sections (autos, bonus depreciation, etc)

4. Apply limitations (basis, at‑risk, passive activity, state differences)

5. Look for exceptions and special rules

Only then do you get your answer.

Why Your Tax Advisor Says “It Depends”

So when Dr. Nip Tuck asks:
“Can I write off my Ferrari?”

And his tax advisor says:
“It depends…”

They’re not being difficult.
They’re being prudent.

Because in tax…

Skipping the sequence doesn’t give you a faster answer—
it gives you the wrong one.

And in tax, the wrong answer is the most expensive one.

Final Thought

Tax is not like medicine.

A simple question often requires layered analysis.
Miss one layer…
And the entire conclusion can fall apart.

That’s how expensive tax mistakes happen.

If you want to stop asking “Can I write this off?”
and actually understand how the tax code works—

Follow me.

I’ll walk you through it the way it actually works in real life.

But for some physicians, it could actually be worth over $500,000 — or even close to $1 million — in tax-free benefits.

The reason sits quietly in the tax code:

IRC §117(d).

Most doctors have never heard of it.

Meet Dr. U.C. Berkeley

Dr. Berkeley, a talented internist, receives two job offers.

Offer #1

• Private practice in Berkeley

• Salary: $420,000.

Offer #2

• Teaching faculty and lecturer at Stanford University Medical School/Medical Center

• Salary: $360,000.

Dr. Berkeley immediately thinks:

“Why would I take a $60,000 pay cut?”

But there is one tax rule most physicians completely overlook.

It lives quietly inside the tax code - IRC §117(d).

And it can be worth hundreds of thousands of dollars.

The Question That Changes Everything

Before rejecting the Stanford academic job because of the lower salary, Dr. Berkeley asked himself one simple question:

“Could my child realistically get into Stanford undergrad?”

If the answer is yes, the economics of the job offer might look very different.

Because some universities offer something called a qualified tuition reduction.

And under the tax law, that benefit may be tax-free.

What IRC §117(d) Actually Does

IRC §117(d) allows a university to provide free or reduced undergraduate tuition to an employee’s child.

When the benefit qualifies as a “qualified tuition reduction,” the value of that tuition is excluded from the employee’s income.

That means:

• No federal income tax

• No Social Security tax

• No Medicare tax

This makes the benefit unusually powerful, since many other employee fringe benefits are taxable.

Back to Dr. UC Berkeley

Dr. Berkeley accepts the Stanford academic job (how ironic!)

Three years later, his son gets accepted to Stanford University as an undergraduate (hallelujah!).

Undergraduate tuition is about $65,000 per year. Ouch!

But Stanford has a tuition reduction program for employees.

So the tuition is fully covered.

Even better — because the program qualifies under IRC §117(d), the value of that tuition is not taxable income to Dr. Berkeley.

That means the IRS does not treat the tuition as salary!

Now here’s where the math gets interesting.

Let’s run the numbers.

• $65,000 per year × 4 years

• That’s $260,000 of tax-free undergraduate tuition.

Now compare that to the $60,000 annual salary reduction.

The “pay cut” suddenly looks very different.

Important Limitations: Undergraduate Only

The §117(d) exclusion generally applies only to education below the graduate level.

Graduate-level tuition reductions are typically taxable unless a specific exception applies, such as certain tuition reductions for graduate students who are teaching or research assistants under IRC §117(d)(5).

Requirement: You Must Work for the University

This is the biggest trap for physicians.

Many physicians working at academic centers are technically employed by:

• a faculty practice group

• a nonprofit medical foundation

• a hospital or health system entity

If you are not legally employed by the university, the §117(d) exclusion can fail - even if the entities are affiliated.

Always confirm which entity is actually listed as your W-2 employer.

Caution: Admission and Plan Rules

Even if you work for the right entity:

• Your child still must be admitted on their own merits.

• The school may require several years of service before benefits vest.

• Some schools cap the percentage or dollar amount of the benefit.

Each university has its own written tuition reduction policy.

The tax code sets the outer limits — but the institutional policy determines what you actually receive.

Strategic Thinking for Physicians

If you have more than one child who may be able to attend the university, the value of tax-free benefit can become very large.

Two kids attending Stanford with $65,000 annual undergraduate tuition:

• $520,000 of potential tax-free education.

If you are in the highest tax brackets in California, that benefit could be economically similar to earning an additional $1M in salary in private practice.

Think about that.

Final Thoughts

When evaluating an academic physician job offer, do not just compare salary.

Compare total economic value.

A properly structured IRC §117(d) qualified tuition reduction can dramatically change the math if:

• you are directly employed by the university

• the school offers meaningful tuition reduction

• your child attends as an undergraduate and is covered by the program

Sometimes the apparent “pay cut” is paired with one of the most valuable benefits in the tax code.

And most doctors never realize it exists.

If you’re not ready to file your individual return, the most important move is simple: file an extension.

An extension gives you more time to file your Form 1040 (usually until October 15).

But it does not give you more time to pay.

Any unpaid tax after the April deadline will still accrue:

• Interest

• A smaller failure-to-pay penalty

Now here’s the real danger:

If you miss the filing deadline and don’t file an extension, the IRS can hit you with a failure-to-file penalty of 5% per month, up to 25%.

That escalates quickly.

How to file an extension in minutes

The fastest way: make an “extension payment” online.

Step 1: Go to irs.gov/payments and Click “Direct Pay with bank account”

Step 2: Click “Pay individual tax”

Step 3: Click “Make a payment”

Step 4: For “Reason for Payment”, select “Extension”.

Step 5: Enter the amount you think you’ll owe and complete the payment process.

Save the confirmation.

If coded properly, this serves as your extension.

How much should you pay?

Think of it like a target:

Add up:

• Withholding

• Estimated payments

Then ask:

“Have I paid at least ~90% of my total tax?”

Or alternatively:

“Have I paid at least 110% of last year’s tax?”

If yes → you’re generally protected from underpayment penalties
If no → pay as much as you reasonably can now

Even partial payment helps reduce interest and penalties.

What If I Don’t Owe Anything?

You still need to file an extension.

Two options:

• Submit Form 4868 (no payment required), or

• Use IRS Direct Pay (easier)

Since the IRS system won’t process a $0 payment, many people submit a $0.01 payment to trigger the extension electronically.

You bought a home before COVID.
Now the value has gone up $600,000, and you want to sell.

People tell you:

“Only $500,000 of that gain is tax-free.”

But I say something different.

You may still pay zero tax when you sell it.

How is that possible?

Why “Sale Price Minus Purchase Price” Is Wrong

Many homeowners assume the gain from selling a house is calculated like this:

• Sale price − purchase price = gain.

That shortcut is wrong under the tax law.

The IRS uses a specific formula to determine taxable gain on the sale of a principal residence:

• Amount realized − adjusted basis = gain.

Meet Dr. Nvidia

After getting his first attending job in Santa Clara, California, Dr. Nvidia bought a small cottage for $1,000,000 in 2019.

This year, he sells it for $1,600,000.

Like most people, he thinks the gain is…

• $1,600,000 − $1,000,000 = $600,000 gain

But the tax law doesn’t calculate it that way.

To determine the real gain, the IRS requires a three-step process.

Step 1 — Calculate the “Amount Realized”

The gain calculation does not begin with the gross sales price.

Instead, you start with the amount realized, which is:

• Sales price - selling expenses.

Selling expenses typically include items on the closing statement that are paid to sell the property, such as:

• Realtor commissions

• Staging or advertising costs

• Transfer taxes (city and county)

• Escrow or attorney fees related to closing

• Title insurance paid by the seller

• Home warranty provided to the buyer

Example

Dr. Nvidia sells his home for $1,600,000.

At closing he pays:

• $60,000 realtor commission

• $10,000 staging

• $20,000 transfer taxes

• $10,000 escrow and title fees

Total selling costs = $100,000

Amount realized:

• $1,600,000 − $100,000 = $1,500,000

This is the number the IRS uses in the gain formula — not the raw sale price.

Step 2 — Calculate Your “Adjusted Basis”

Next, we determine what the home actually cost you for tax purposes.

That’s your adjusted basis.

Start with the purchase price.

Then adjust for certain costs, including:

• Certain buyer closing costs that are capital in nature

• Transfer taxes on purchase

• Buyer’s agent commission (if you paid it)

• Capital improvements made over the years

Capital improvements generally include items that add value or prolong the life of the property, such as:

• New roof

• New HVAC system

• Kitchen remodel

• Built-in appliances (like a Wolf stove)

• Structural additions

• Permanent landscaping or hardscaping

• ADU construction

Repairs do not count.

Painting, fixing leaks, and minor patch work are typically repairs and do not increase basis.

If you ever claimed depreciation on the home (for example during a rental period or for a home office), that depreciation reduces basis and the gain attributable to that depreciation cannot be excluded under §121.

Example

Dr. Nvidia purchased the home for $1,000,000 in 2019.

At purchase he paid:

• $5,000 buyer’s realtor fee

• $5,000 transfer tax

Later he installed:

• New roof

• New AC system

• Wolf stove

Total improvements = $40,000

Adjusted basis becomes:

• $1,000,000 (purchase price)

• + $5,000 buyer’s realtor fee

• + $5,000 transfer tax

• + $40,000 in improvements

Adjusted basis = $1,050,000

Step 3 — Calculate the Gain

Now we compare the two numbers.

• Amount realized: $1,500,000

• Adjusted basis: $1,050,000

• Gain = $450,000

This is the gain before applying the §121 exclusion.

The Powerful Tax Break Under IRC §121

IRC §121 is a tax provision that I believe every doctors should understand as part of basic tax literacy.

Why?

Because it is one of the most taxpayer-friendly rules in the entire tax code, and it applies to almost every homeowner.

Under Internal Revenue Code §121, a homeowner who sells a principal residence can exclude:

• Up to $250,000 of gain if single

• Up to $500,000 of gain if married filing jointly

For physicians living in high-cost areas like California, this exclusion can eliminate a very large tax bill — sometimes entirely.

But first, you must calculate the gain correctly.

Applying the §121 Exclusion

If married filing jointly and the couple meets the §121 tests:

• $450,000 gain − $500,000 exclusion

• Taxable gain = $0

The entire gain is excluded because it is below the $500,000 cap.

If single:

• $450,000 gain − $250,000 exclusion

• Taxable gain = $200,000

That amount may be subject to capital gains tax and possibly the 3.8% Net Investment Income Tax (NIIT) depending on income levels.

Key Requirements for the §121 Exclusion

To qualify for the full exclusion under IRC §121, you must generally:

• Own the home for at least 2 years during the 5-year period before the sale

• Use the home as your principal residence for at least 2 years during that same period

• Not have used the §121 exclusion on another home sale in the previous 2 years

Most doctors who live in their primary residence satisfy these rules.

However, complications can arise in situations such as:

• Converting the home to a rental (nonqualified use rules)
• Home office depreciation under the actual-expense method.
• Short ownership periods
• Divorce or other unforeseen events (which may allow a partial exclusion)

Why This Matters for Doctors

Many doctors live in rapidly appreciating housing markets.

It is common to see $500,000 or more in appreciation over 5–10 years.

If you fail to track:

• Capital improvements

• Purchase closing costs that increase basis

• Selling expenses

you could overpay tens of thousands of dollars in capital gains tax.

Doctor Takeaway

Understanding IRC §121 is not an advanced tax strategy.

It is basic tax literacy.

Because almost every physician will sell a home at some point in their career.

Final Thought

When that day comes, IRC §121 can either be your best friend…

or a very expensive missed opportunity.

You stare at it.

Two years of stress. Sleepless nights. Therapy. Feeling pushed out of a hospital you once trusted.

Finally… justice.

And then your CPA says:

“About half of this may go to taxes.”

Wait—what?

You paid the price.

Why is the IRS getting paid too?

Meet Dr. Neuro Logic

Dr. Neuro Logic is a neurologist with multiple sclerosis (relapsing-Remitting MS).

Brilliant. Dedicated. Quietly resilient.

But over time, something changed.

Whispers in the hallway. Subtle exclusion. Then not-so-subtle comments.

She believes it’s tied to her condition.

Her MS symptoms worsen.

• Fatigue.

• Headaches.

• Anxiety.

• Depression.

She spends thousands on therapy.

Eventually, she can’t take it anymore.

She quits. She sues.

Two long years later…

The jury agrees.

$500,000.

She wins.

She walks into her CPA’s office, smiling:

“This should be tax-free, right? After everything I went through?”

Her CPA reads the settlement agreement.

Silence.

Then…

“I’m sorry. This is mostly taxable.”

Her smile disappears.

“Why?”

The Rule That Feels Unfair

Here’s the uncomfortable truth:

The IRS does not tax your pain.

The IRS taxes what the money is for.

And that distinction changes everything.

Step 1: The Default Rule — IRC §61

Under §61, gross income means “all income from whatever source derived.”

The Supreme Court in Glenshaw Glass defined income as:

• An accession to wealth

• Clearly realized

• Over which you have complete control

In plane english:
If you receive money that you control, from a completed event - you have income.

Dr. Neuro Logic received $500,000.

That’s income.

Unless…

An exception applies.

Step 2: The Exception — IRC §104(a)(2)

There is a powerful exception.

Under §104(a)(2):

Damages received on account of personal physical injuries or physical sickness are excluded from income.

• If your settlement is for physical injuries or sickness → tax-free.

• If not → taxable.

So the real question is:

What was Dr. Logic’s $500,000 actually for?

What Qualifies (and What Doesn’t)

Generally tax-free:

• Damages for physical injuries (e.g., broken arm)

• Damages for physical sickness (e.g., worsening MS)

• Medical costs tied to those conditions

Generally taxable:

• Lost wages or back pay

• Interest

• Punitive damages (almost always taxable)

• Emotional distress (by itself)

Here’s the trap:

Emotional distress ≠ physical injury or sickness under §104.

Small exception:

You can exclude medical expenses for emotional distress (e.g., therapy)—but not the distress itself.

The Critical Doctrine: “Origin of the Claim”

This is everything.

The tax outcome depends on:

=> What the lawsuit was actually about
Not how you felt
Not what happened medically

But what the legal claim says.

Courts look at:

• The complaint

• How the case was argued

• Settlement language

• Payor’s intent

Key rule:

The tax result depends on the origin of your claim -
not what you later wish it said.

Why Dr. Logic Lost the Tax Benefit

She had:

• Anxiety

• Depression

• Headaches

• Worsening MS symptoms

But her case focused on:

• Discrimination

• Workplace retaliation

• Emotional distress

Her settlement agreement?

It did not clearly say the payment was for physical injury or physical sickness.

IRS conclusion:

=> Employment + emotional distress case = taxable

The Dangerous Misunderstanding

A very common belief:

“If stress caused physical symptoms, the settlement should be tax-free.”

Not quite.

The IRS draws a hard line:

Emotional distress ≠ physical injury or physical sickness

Even if it causes:

• Insomnia

• Headaches

• Stomach issues

These are treated as symptoms of emotional distress, not separate physical injuries or sickness.

A Real Case: Why Wording Matters

In Stassi v. Commissioner:

The taxpayer developed a real physical illness (shingles).

But:

• The lawsuit focused on emotional distress

• The settlement did not tie payment to physical injuries or sickness.

Result?

=> Taxable.

Same suffering.
Different wording.
Different tax outcome.

The Entire Game Comes Down to Words

If your settlement agreement says:

“On account of physical injury or physical sickness”
→ Strong path to tax-free

If instead it says:

“Emotional distress with physical manifestations”
→ Likely taxable

This can be the difference between:

$0 tax
vs.
$200,000+ tax bill

Why This Matters for Physicians

Doctors often experience:

• Burnout

• Hostile work environments

• Retaliation

And real physical consequences:

• Autoimmune flares

• Shingles

• Cardiac symptoms

But:

If your case is framed as employment stress instead of physical sickness

=> You may lose the §104 exclusion

Timing Is Everything

By the time the check hits your bank account…

The tax outcome is already decided.

Not by your CPA.
Not by your intentions.
Not by how much you suffered.

But by what was written—months earlier.

Once:

• Complaint is filed
• Settlement is signed

Your flexibility is gone

Because courts don’t ask:

“What actually happened to you?”

They ask:

“What did your legal documents say happened?”

They rely on:

• The original story on paper (the “origin of the claim”)

• Not the story you try to tell later

In other words:

You don’t win this battle after the lawsuit ends.

You win it when the lawsuit is written.

Same facts. Same pain. Different wording… completely different tax bill.

Final Thought

Dr. Neuro Logic didn’t lose because she didn’t suffer.

She lost because the law didn’t see her suffering the way her documents described it.

In tax…

Words = reality.

The difference between:

“Emotional distress”

and

“Physical sickness”

can be worth hundreds of thousands of dollars.

Pain may be unavoidable.

But taxes on that pain?

Sometimes avoidable — if structured correctly

If you’re ever in this situation:

Make sure your attorney and tax advisor align BEFORE signing anything.

Because in tax…

The story on paper is the only story the IRS hears.

“Buy rental property.
Have your non‑working spouse qualify as a real estate professional (REPS).
Generate losses. Offset your W‑2 income.”

Sounds amazing.

Almost too amazing.

Because here’s the truth:

Most of these cases fail.

And the IRS knows it.

Why the IRS Is Skeptical

The typical setup looks like this:

• Physician → full‑time W‑2

• Spouse → “real estate professional”

• A few rental properties

• Large rental losses used to offset W‑2 income

The IRS sees this all the time.

And their default assumption?

“This spouse didn’t actually do enough work.”

Especially when:

• No real‑time logs

• Vague descriptions (“managed property”)

• Heavy use of property managers

• Hours reconstructed only after the audit starts

Enter: Birdsong v. Commissioner

This is where Birdsong v. Commissioner changes the narrative.

Facts:

• Husband: ER physician

• Wife (Roberta Birdsong): not employed, managing rentals

• Two Oakland properties (4-unit + 5-unit = 9 units total)

The strategy worked like this:

• Wife qualifies as a real estate professional

• She materially participates

• Rental losses become nonpassive

• Losses offset W-2 income

The IRS response?

“We don’t believe your hours.”

They challenged:

• Real estate professional status under IRC §469(c)(7)

• Material participation

• Credibility of her time logs

And proposed:

• Back taxes

• ~ $10,000 in penalties

What Made This Case Different

Roberta didn’t just “own rentals.”
She ran a rental business.

What she actually did:

• Cleaned common areas

• Collected laundry machine coins

• Performed repairs

• Communicated with tenants

• Collected and deposited rent

• Maintained insurance

• Bought materials (Home Depot trips)

• Paid bills and kept books

• Researched contractors and obtained multiple bids

• Supervised repairs

• Advertised vacancies

• Screened tenants

• Showed units

• Processed applications

No delegation.
No fluff.

Just consistent, hands-on work.

The Killer Move: Documentation

This is where she separated herself from most taxpayers.

She kept:

• Two detailed spreadsheets

  • Log #1: 844 hours

  • Log #2: 1,136 hours (expanded log)

• Narrative descriptions of tasks

• Invoices, calendar and receipts that lined up with her logs

• Testimony that matched the records

Everything lined up.

That’s what made it credible.

The Law (And Why They Won)

#1: Real Estate Professional Test

Under IRC § 469(c)(7),

• Perform 750+ hours in real estate activities

• Spend more time in real estate than any other trade/business

She passed.

#2: Material Participation

Under Treas. Reg. §1.469-5T:

• 500+ hours = material participation

She passed.

#3: Reasonable Means of Proof

Under Treas. Reg. §1.469-5T(f)(4)

You don’t need perfect logs.

But you need:

• Credible

• Consistent

• Supported records

Not:

• Estimates

• Vague recollections

• “I think I worked a lot”

Her logs met the standard.

What the Court Said

The Court found

• She testified credibly and in detail

• Her logs were thorough and convincing

• Her activities showed real, active management

Result:

• Real estate professional status allowed

• Losses allowed

• Penalties removed

The Real Lesson (This Is Where Most People Fail)

Let’s be blunt.

Most physicians trying this strategy:

• Don’t track hours

• Overestimate involvement

• Delegate to property managers

• Recreate logs during audit

That fails.

Every time.

Dr. Taxtor Takeaway

If you want this strategy to actually work:

#1: Do the work (“Be a Man. Do the Right Thing - Russel Peters”)
Not “own property” → operate the business

#2: Track in real time
Not during audit panic mode

#3: Keep layered proof

• Logs

• Calendar

• Receipts

• Narrative

#4: Make it defensible

Because eventually…

You may have to defend it.

Final Thought

This isn’t about a loophole.

It’s about credibility.

Roberta Birdsong didn’t win because of a clever strategy.

She won because she actually did the work…
…and she proved it.

That’s the difference.

Be like Birdsong

(As a fellow ER doc—I’m proud of you.)

If You Want to Do This Right

Most people only think about documentation after the IRS shows up.

By then, it’s usually too late.

If you want to get ahead of that, I offer consultations where we structure your activities and records the right way—from the start.

You can book a consultation here.

I take on a small number of these each month so I can stay hands-on.

There’s a conference in Santiago de Chile from June 11-12, 2026

Two-day conference. Great speakers. Beautiful location.

You think:

“Perfect. I’ll learn… and write off the trip.”

So you book:

• Flight to Chile

• The Ritz-Carton Hotel

• A few extra days for sightseeing

And in your head:

“This is 100% deductible.”

Pause.

That’s where even a Harvard‑trained, world‑class surgeon Dr. G can get it wrong.

The Rule Everyone Knows (and Where They Stop Too Early)

Most doctors stop here:

Internal Revenue Code §162(a)(2)

If it’s a business trip,

• Flights

• Hotels

• Meals

→ Deductible if ordinary, necessary, not lavish.

That’s true.

But incomplete.

Because IRC §162 only answers:

“Is this a business expense?”

It does NOT answer:

“How much is actually deductible”

Where the IRS says: “Not so fast”

When you leave the U.S., a second rule kicks in:

IRC §274(c)

Treas. Reg. §1.274-4

These rules:

• Separate business vs. personal days

• May force you to split airfare

• Disallows expenses on personal days

This is where most “write off the whole trip” advice breaks.

The Real Game: Your Calendar

The IRS looks at:

1. Why you took the trip

2. How each day is spent

3. The ratio of business vs. personal days.

Your calendar controls your deduction.

What Counts as a “Business Day”?

Under Treas. Reg. §1.274‑4:

Business days include:

• Travel days

• Conference/meeting days

• Days where your main activity is business

• Days you’re forced to miss business (e.g., cancellation)

• “Sandwich” weekend (between business days)

Everything else = personal day.

And:

• Hotel/meals on personal days → not deductible

• Even if airfare is deductible

The First Fork: Business or Vacation?

Ask honestly:

Why did you go?

If the reason is primarily personal (e.g., vacation):

• Airfare: 0% deductible

• Only direct business expenses (e.g., conference fees) are deductible

If primarily business:

• Airfare may be deductible

• But you must pass additional tests.

Key mistake:

Conference ≠ automatically a business trip.

The Two Key Rules

If the trip is primarily for business, airfare is 100% deductible if:

• Trip ≤ 7 days
  OR

• Personal days < 25%

Fail both → airfare must be allocated.

How Counting Works (simple version)

7-day rule:

• Count days outside the U.S.

• Exclude departure day

• Include return day

25% rule:

• Count all days

• Classify each day as business vs personal

• Personal days ÷ total days

Putting Numbers on It

Assume:

• Airfare: $1500

• Hotel: $300/day

• Meals: $200/day (deductible amount)

• Total: $5000

Example 1: “Tax-Efficient” Calendar

• Duration: 7 days (6/10-6/17, excluding 6/10 per 7-day rule above)

• Classification:

  • 6 business days

  • 1 personal day

Why it works:

• trip duration ≤ 7 days → full airfare deduction allowed

Result:

• Airfare: $1,500 deductible

• Hotel/meals: 6/7 deductible

Total ≈ $4500 deductible

Example 2: Longer but Still Efficient

• 14 days

• 11 business / 3 personal

• Total expense: $8500

Why it works:

• 3 personal ÷ 14 days = 21% (<25% personal days)

Result:

• Airfare: 100% deductible

• Hotel/meals: prorated, 79% deductible => $5500

Total ≈ $7000 deductible

Example 3: Looks fine… but fails

• 14 days

• 6 business / 8 personal

Why it fails:

• 8 personal ÷ 14 = 57% (> 25% personal days)

Result:

• Airfare: prorated, 43% deductible => $600

• Hotel/meals: prorated, 43% deductible => $3000

Total ≈ $3600 deductible

Example 4: The Common Mistake

• 14 days

• 2 conference days

• 1 Travel day (to Chile)

• 11 vacation days

• Total expense: $8500

Why it fails:

• 11 personal ÷ 14 = 79% personal (> 25% personal days)

• Trip is primarily personal

Result:

• Airfare: 0% may be deductible

• Hotel/meals: severely limited, only potentially for 3 days => $1500

Total ≈ $1500 deductible

The Smart Physician Move

Same trip. Better structure:

• 6/10 Wed: Fly

• 6/11-12 Thu–Fri: Conference

• 6/13-14 Sat–Sun: Weekend

• 6/15-16 Mon–Tue: Meetings

• 6/17 Wed: Fly home

Under Treas. Reg. §1.274‑4:

• Travel days (6/10 and 6/17): business days

• Conference days (6/11–12): business days

• Weekend (6/13–14) between business days: treated as business days (“sandwich” days)

• Meeting days (6/15–16): business days

Why this works:

• Weekend (6/13-14) becomes business (sandwich rule)

• Every day counts as business

• Trip clearly primarily business

Result:

• Airfare: 100% deductible

• Hotel/meals: 100% deductible

Same trip. Completely Different outcome.

The Mental Model

Don’t ask:

“Is this deductible?”

Ask:

“How will each day be classified?”

Because:

Your calendar = your tax outcome.

The strategy Most Doctors Miss

If you’re going overseas:

• Keep trips ≤ 7 days when possible

• Use sandwich weekends

• Add real business before/after weekends

• Avoid fake “token meetings”

Small changes.

Big difference.

Final Thought

The IRS doesn’t care about Patagonia.

They care about:

• Why you went

• What you did each day

• How those days classify

Same trip.
Same cost.

One doctor deducts $7,000.
Another deducts $1500.

The difference?

Not luck.
Not income.

Smart tax planning.

Share Tax Clinic for Doctors

This post is dedicated to Dr. Neil — real estate entrepreneur extraordinaire — and Dr. Park, quietly building an STR empire.

“$20,000… for an HVAC?”

I didn’t know it cost that much either.

Until it happened to me.

Last summer, I got the call every landlord dreads.

“Hey… the AC is making a loud noise.”

I sent a technician out, hoping for a quick fix.

Maybe a few hundred bucks.

In and out. Move on.

Instead, I get the call back.

“It’s over 20 years old. It’s done. You need a full replacement.”

Pause.

“How much?”

“About $20k.”

Damn.

The Part That Hurts Even More

It’s not just the $20k.

It’s what tax law does with it.

For long-term residential rentals, HVAC is treated as part of the building.

That means, 27.5-year depreciation under MACRS.

So your $20k expense?

About $700 deduction a year for a long 27.5 years.

Slow. Painful.

You feel the cash hit today, but the tax benefit drips out… over decades.

If you own rentals, this isn’t rare.

This is just another Tuesday.

Where Most Landlords Miss The Tax Remedy

When something like HVAC fails, most landlords do the obvious thing:

Replace it… and move on.

But they miss the better question.

“What happened to the old component I’ve been depreciating?”

The Rescue Provision

Buried in the regs is partial asset disposition. Treas. Reg. §1.168(i)-8(d).

A tax-smart landlord’s best friend.

It doesn’t change how you treat the new HVAC.

But it lets you write off the old one — instead of continuing to depreciate something that’s already in the dumpster.

Real Numbers (What I Actually Did)

Step #1: Determine the old HVAC basis

• Rental purchase price: $700,000

• Land (20%): $140,000

• Building (80%): $560,000

Using a reasonable estimate, I allocated 2% of the building to HVAC.

• Old HVAC basis ≈ $560,000 x 2% = $11,200

Step #2: Calculate depreciation

Assume:

• Placed in service as a rental: 1/1/2025

• HVAC replaced: 6/30/2025

Depreciation:

• $11,200 ÷ 27.5 years × 6/12 months ≈ $203

Adjusted basis ≈ $11,200 − $203 ≈ $11,000 per Treas. Reg. §1.168(i)-8(f)

Step #3: Apply partial asset disposition

Now the moment that matters.

You replace the HVAC.

You throw the old one away.

• Amount realized = $0

• Adjusted basis ≈ $11,000

• Ordinary loss: ≈ $11,000

That becomes a current-year loss.

Reported on Form 4797, Sales of Business Property.

Same broken HVAC.

Now it creates a real deduction.

Meanwhile…

The new $20,000 HVAC?

Still capitalized. Still depreciated over 27.5 years.

Nothing fancy there.

The strategy isn’t about accelerating the new.

It’s about not dragging the old.

Guardrails (Don’t Skip This)

If you do this, do it correctly:

• Use a reasonable method to support the allocation

• Reduce the building basis accordingly

• Stop depreciating the old HVAC

• Report the disposition on Form 4797

And remember:

If the activity is passive, the loss remains passive.

Final Thought

The HVAC still broke. You still paid $20,000.

That doesn’t change.

But your tax outcome?

Completely different.

Most landlord keep depreciating that old HVAC that’s already in a landfill.

A few carve it out…

And take the loss now.

Same expense.
Different awareness of the tax rule.
Much better tax outcome.

“What if I go on a cruise with my family, attend a few CME lectures… and deduct the entire trip as a business expense?”

After all, there are a ton of websites advertising “CME Cruises.”

They appears to promise something that sounds magical:

Vacation + CME + Tax Deduction

If the organizers are selling these trips, they must be deductible… right?

Not so fast.

The tax code has already anticipated this idea.

And it placed some very specific guardrails around it.

Meet Dr. Cruz

Dr. Cruz is a successful, entrepreneurial-minded cardiothoracic surgeon.

One night he dreams of the perfect trip: an eight-day Mediterranean cruise with his family.

• Beautiful ocean views.
  Santorini sunsets.
  And somewhere between the buffet and the pool deck… a lecture on hypertension management.

Best of all, he imagines deducting the entire trip as a business expense.

The next morning he wakes up and thinks:

“Wait… why can’t I actually do that?”

So he Googles “CME cruises.”

• CME Cruises

Dozens of options appear.

One looks perfect: an 8-day Mediterranean cruise.

• Rome → Santorini → Kusadasi → Mykonos → Rome

The package includes:

• 12 CME credits (4 hours of lectures × 3 days)

• About 40 U.S. physicians attending — many bringing their families

• A CME organizer based in Las Vegas

The costs look like this:

• Airfare from San Francisco to Italy: $1,000

• Cruise fare: $1,000

• Live CME course: $2,000

• Total: $4,000 per person.

Before booking, Dr. Cruz calls the CME organizer and asks:

“Is this tax-deductible?”

The organizer says yes.

Dr. Cruz thinks:

“If they’re selling it, they must know the tax rules.”

Unfortunately…

The IRS has a different opinion.

The First Problem: Foreign Conferences

The key rule here is IRC §274(h).

This Code section applies to conventions held outside the “North American area.”

The North American area generally includes:

• United States

• Canada

• Mexico

• U.S. possessions

Europe is obviously not included.

So when a conference is held outside this area, the taxpayer must prove something important:

• It must be as reasonable to hold the meeting outside North America as within it.

That usually means things like:

• The organization is based overseas

• Many participants are from that region

• There is a strong business reason to hold the meeting there

But Dr. Cruz’s cruise looks like this:

• Organizer: Las Vegas

• Attendees: U.S. physicians

• Location: Mediterranean cruise

• There is no real business reason for this conference to be held in Europe.

That alone puts the deduction in serious trouble.

The Second Problem: Cruise Ship Rules

Even if the foreign conference rule somehow worked, another rule applies.

IRC §274(h)(2) specifically covers conventions held on cruise ships.

To qualify, two conditions must be satisfied:

1. The cruise ship must be registered in the United States

2. All ports of call must be in the United States or U.S. possessions

Dr. Cruz’s itinerary looks like this:

• Rome, Italy => Santorini, Greece => Kusadasi, Turkey => Mykonos, Greece => Rome, Italy

Not exactly U.S. territory.

So the cruise seminar fails this test as well.

The Third Problem: Even If It Qualified…

Let’s imagine a perfect scenario.

• A U.S.-registered cruise ship.

• Ports only in Puerto Rico and the U.S. Virgin Islands.

• Lectures held onboard.

Even then, the tax code adds one more restriction.

IRC §274(h)(2) caps the deductible amount at:

• $2,000 per person per year.

So even a perfectly structured cruise seminar cannot produce unlimited deductions.

What Happens to Dr. Cruz?

When all the rules are applied, here’s the likely outcome.

• Cruise fare: nondeductible

• Cruise lodging: nondeductible

• Cruise meals: nondeductible

• Airfare to Italy: nondeductible

The only possible deduction may be the CME tuition - and only if he actually attended the lectures.

The result?

• Dr. Cruz gets an amazing Mediterranean vacation.

• But only a fraction of it is deductible.

When Can a CME Cruise Be Deductible?

A cruise-based CME program can qualify only if all of these conditions are satisfied:

• The lectures are held on the ship

• The ship is U.S.-registered

• All ports are in the U.S. or U.S. possessions

• The program is directly related to the physician’s trade or business

And even then:

• The deduction is capped at $2,000 per person per year.

The Big Lesson

“CME cruise + tax deduction” sounds clever.

But the tax code has already thought about that idea.

And it closed most of the loopholes.

Final Thought

If you are planning to mix a cruise with CME, it is important to ask a few key questions first:

• Are the requirements outlined in IRC §274(h) satisfied?

• Is the trip primarily business, or primarily vacation?

Because when the IRS looks at the full picture, a beautiful Mediterranean cruise can quickly turn into nothing more than a very expensive personal vacation.

The plan sounded simple.

He would loan her $200,000 for the down payment so she could purchase the new house first. Then, once she sells her current home, she would pay him back.

Situations like this come up all the time.

When people think about how to structure a loan between family members, two ideas usually come up:

• Make an interest-free family loan, or

• Gift the money now and have mom give it back later

At first glance, both seem simple and financially reasonable.

But the tax consequences can be very different from what people expect.

Let’s walk through them.

Option 1: The 0% Family Loan

A loan with little or no stated interest is called a below-market loan if the rate is lower than the Applicable Federal Rate (AFR). The rules for these loans are found in Internal Revenue Code §7872.

For simplicity, let’s focus on the type most families actually use: a demand loan.

A demand loan means the lender can ask for repayment at any time. That fits our example. The son expects mom to repay him when her house sells, but there is no fixed maturity date.

Under IRC §7872, if a demand loan charges less than the AFR, the IRS pretends interest was charged anyway.

For tax purposes, the law treats the transaction as if the following happened each year:

• The son makes a gift to mom equal to the foregone interest

• Mom immediately pays that same amount back to him as interest

So the interest essentially bounces back and forth on paper.

Example

Assume the following:

• Loan amount: $200,000

• Stated interest rate: 0%

• Short-term AFR: 5%

• Loan outstanding for one full year

The imputed interest would be:

$200,000 × 5% = $10,000 of foregone interest

For tax purposes, the IRS treats the situation as if:

• The son gave mom a $10,000 gift

• Mom paid the son $10,000 of interest

Tax result

On the son’s side:

• He must report $10,000 of interest income. If he is in the 37% bracket, that’s about $3,700 of federal tax.

• At the same time, he is treated as having made a $10,000 gift.

Fortunately, the gift is below the 2026 annual gift exclusion of $19,000 per recipient, so no gift tax return is required.

If the deemed gift exceeded $19,000, the son would typically have to file Form 709, even though no tax would likely be due because of the large lifetime exemption.

Under current law, the lifetime estate and gift exemption is $15M per individual in 2026, and it will be indexed for inflation starting in 2027.

Now let’s look at mom’s side.

Mom is treated as having paid interest.

But personal interest is generally nondeductible under IRC §163(h) unless it qualifies for a specific exception.

One important exception is qualified residence interest under IRC §163(h)(3).

For that to work in a family-loan situation, the loan typically must:

• Be properly documented

• Be secured by the home (mortgage or deed of trust)

• Be used to acquire the residence

• Stay within the acquisition-debt limits ($750k for a single person)

If the loan is simply an informal IOU between family members, mom’s deemed interest usually is not deductible.

So the end result can be:

• Taxable interest income to the son

• No deduction for mom

Not exactly what most families had in mind.

As the saying goes, no good deed goes unpunished.

Option 2: “Gift It Now, Gift It Back Later”

Another idea people sometimes suggest is this:

• The son gifts $200k to mom today

• When she sells her house, she “gifts” $200k back to him

From a gift-tax standpoint, this may not create any actual tax liability because of the large lifetime exemption (i.e., $15M in 2026).

However, there are still consequences and risks.

First, the son’s $200,000 transfer exceeds the $19,000 annual gift exclusion amount.

That means $181,000 would be a taxable gift, which must be reported on Form 709, and it would use part of his lifetime exemption.

Second, if everyone expects from the beginning that mom will pay the money back when her house sells, the IRS may argue that $200k was never really a gift.

Labeling a transfer a “gift” does not automatically make it one if there is a clear expectation of repayment.

If the IRS recharacterizes the transaction as a loan, then the below-market loan rules under §7872 would apply anyway, just like in Option 1.

Which means the son could still end up recognizing imputed interest income.

Ouch. Ouch. Ouch.

Small Loan Rules Under IRC §7872

There are two small-loan rules in §7872 that sometimes help with family loans.

#1: Loans of $10,000 or less

If the total outstanding loans between the parties are $10,000 or less, the imputed interest rules generally do not apply.

However, this exception does not apply if the money is used to purchase income-producing assets (for example, mom buying a used Honda Accord to start a Turo business).

In our $200,000 example, this rule clearly does not help.

#2: Loans of $100,000 or less

If total loans between individuals do not exceed $100,000, the lender’s imputed interest income is limited to the borrower’s net investment income.

Net investment income includes things like:

• Interest income

• Dividends

• Rental income

• Other investment income

If the borrower’s net investment income (in this case, mom’s) is $1,000 or less, it is treated as zero for this rule.

So in that situation, no interest would be imputed to the lender (the son) for income-tax purposes.

However, this rule only limits the income tax impact.
It does not limit the deemed gift for gift-tax purposes.

In our $200,000 example, this rule also does not apply because the loan exceeds $100,000.

The Practical Structure Most Families Use

In real life, the cleanest solution is usually a properly documented family loan that charges at least the AFR.

That typically means:

• A written promissory note

• An interest rate at least equal to the AFR

• A clear repayment term (for example, when mom’s house sells)

If interest deductibility for mom is important, the loan should also:

• Be secured by the home with a recorded mortgage or deed of trust

• Meet the requirements for qualified residence interest

• Stay within the $750,000 acquisition-debt limit

A properly structured loan avoids the imputed-interest problem and matches the real economic intent of the family.

Final Thought

Helping family members financially, especially with housing, is common and often the right thing to do.

But once the dollar amounts get large, the tax rules can produce results that people don’t expect.

Under IRC §7872, a “simple” 0% family loan can quietly generate taxable interest income and deemed gifts each year.

Before moving large amounts of money within a family, it’s worth taking a moment to decide:

• Is this really a gift?

• Or is it really a loan?

And if it’s a loan, structuring it properly can prevent an unnecessary tax bill.

Sometimes a small change in documentation and interest rate can make a big difference.

Maybe you want to use those miles for a vacation to Hawaii.

A natural question comes up:
Are those miles tax-free, or taxable?

The General Tax Rule

If your gut says the IRS would tax it, that’s actually a pretty good instinct.

Under the general definition of gross income found in IRC §61 and the Supreme Court case Glenshaw Glass v. Commissioner, income includes any clear increase in wealth that you have control over and that is clearly realized.

In simple terms: if you get richer, the tax law usually wants a piece of it.

By that logic, free travel from miles could look like taxable income.

What the IRS Said

But here’s the interesting part.

The IRS addressed this directly in Announcement 2002-18.

In plain English, the IRS said it will not tax the value of the frequent flyer miles earned from business travel and later used personally.

Why?
Administrative headaches.

Tracking miles, assigning a dollar value, and separating business vs. personal use would be messy and impractical at scale.

So the IRS essentially said: we’re not going to chase this.

Practically speaking, if you earn miles from work-related travel (for example, locums travel) and later redeem them for a personal trip - like that Hawaii vacation - the IRS has publicly said it will not pursue this as taxable income.

Important Limits to This Position

There are limits to this non-enforcement position.

The IRS specifically warned that this approach does not apply if the rewards are converted to:

• cash or cash equivalents

• an arrangement effectively provides additional compensation (for example, an employer giving miles or points as part of your pay)

• a structure that begins to look like a tax-avoidance scheme rather than routine travel-rewards.

So the clean approach is simple: use the miles for travel, not for cash or compensation-style arrangements.

Practical Takeaway for Locums Doctors

If you earn miles the old-fashioned way - by flying for work - and redeem them for personal flights or hotels in the normal way, the IRS has said it will not pursue those benefits as taxable income.

Final Thought

Locums travel is exhausting.

If you’re earning miles from all those flights and using them for a personal trip, this is one of the rare areas where the IRS has effectively said:

“We’re not policing this.”

Enjoy the fruit of your labor.

Just keep it boring: miles for travel, not miles for cash.

They pull up Pub 463, Travel, Gift and Car Expenses, to determine whether they can deduct certain expenses.
They skim the examples.
they see language that seems to apply.

And they assume:

“If the IRS said it, I’m safe.”

Not exactly.

Here’s the uncomfortable truth that surprises a lot of people.

Tax Pearl:

IRS publications are not binding legal authority. They are helpful summaries, but they are not “the law,” and they are not considered “substantial authority” for a tax position in controversy. Courts have consistently warned taxpayers that reliance on IRS publications is at their own risk.

Let that sit for a second.

Why This Actually Matters

IRS publications are written to simplify complex tax law for the general public. That’s their purpose.

But simplification has a cost.

Nuance gets lost.
Technical requirements get shortened.
Exceptions get glossed over.
Legally precise words get softened for readability.

And when a simplified explanation conflicts with the actual law?

• The Internal Revenue Code wins.

• The Treasury Regulations win.

• The courts win.

• The IRS publication loses.

In cases like Adler v. Commissioner, the court refused to let a taxpayer rely on an IRS publication to override the tax law when claiming dance lessons as a medical deduction. The court made it clear: IRS publication cannot change the meaning of the tax law.

Thank about that.

You could rely entirely on an IRS publication.
You could follow it in good faith.
You could still lose in Tax Court if it conflicts with the Code, regulations, or controlling case law.

So Why Does the IRS Publish Them?

Because tax law is complicated.

Congress writes the law.
Treasury writes regulations interpreting that law.
Courts interpret both.

No busy doctors with a full clinical schedule is going to sit down and analyze IRC § 199A word by word to understand every limitation embedded in the qualified business income deduction.

So the IRS translates the law into plain English.

The goal is accessibility.
Not legal precision.

That’s the trade‑off.

How Do You Know if Your Tax Position is Defensible?

You start with the actual hierarchy of authority for federal tax law.

From strongest to weaker:

1. Internal Revenue Code (the supreme tax law of the land)

2. Treasury Regulations

3. Court cases

4. IRS rulings and procedures (revenue rulings, revenue procedures, notices, announcements, etc.)

5. IRS publications and other explanatory materials

Items #1-4 are where serious tax positions should be grounded.

IRS publications are secondary authority. They explain. They do not control. They are not substantial authority. They do not bind the IRS. They do not bind the courts.

This is why serious tax planning cannot rely on publications alone.

If you are taking a meaningful position - a large dollar deduction, entity structuring, real estate professional status, material participation, cost segregation, 199A aggregation - you want your position anchored in:

• Specific Code sections

• Applicable Treasury Regulations

• Supporting case law

• Where relevant, on-point IRS rulings or procedures

Not just a convenient paragraph from Pub 463.

This is also why two tax professionals can give different answers.

One may be quoting a IRS publication.

The other may be reading the Code, regulations, and cases directly.

Only one of those approaches aligns with the actual hierarchy of authority when the issue is litigated.

Final thought

Publications are a useful starting points. They are educational tools.

If you are making real money, investing in real estate, running a practice, claiming a significant deductions, or structuring entities, your advice should be anchored in the Internal Revenue Code, regulations, case law, and official IRS pronouncements.

IRS publications can help explain the law.

They are not the law.

Authority matters.
Hierarchy matters.
