Short Term Rental Tax Loophole: A 2026 Guide for Physicians
Updated: Sep 25
If you've looked into using real estate to offset your clinical income, you've probably run into real estate professional status. It asks you to perform "more than 750 hours of services during the taxable year in real property trades or businesses in which the taxpayer materially participates" (26 U.S.C. 469(c)(7)(B)(ii)), and more than half of all your working hours have to land there too.
That second half is the killer. Your clinical hours are the majority of your work, and they don't count. We cover it in full in Real Estate Professional Status for Physicians.
The short term rental approach doesn't require it. The mechanism is real and it sits in the regulations, but it's oversold constantly, usually with the conditions left off.
Here is what it actually takes. A generalist preparer can file this return correctly and still never flag the three places it breaks, and all three turn on how a physician's week actually runs.

Why are rental losses normally stuck?
A rental property is passive by default, and the regulation is blunt about it. An activity is passive if it "is a rental activity, within the meaning of paragraph (e)(3) of this section." The definition applies "without regard to whether or to what extent the taxpayer participates" (Temp. Treas. Reg. 1.469-1T(e)(1)(ii)).
Read that last clause again. How hard you work doesn't matter.
That's why a paper loss on a rental usually can't touch your W-2. It goes into the passive bucket and waits there until you have passive income or you sell.
What is the short term rental tax loophole?
People call it the STR loophole or the STR tax loophole, and it applies to an Airbnb or Vrbo the same way it applies to a cabin you book yourself. It's an exception to the definition of a rental activity, not an exception to the passive loss rules.
An activity involving tangible property isn't a rental activity for the year if "the average period of customer use for such property is seven days or less" (Temp. Treas. Reg. 1.469-1T(e)(3)(ii)(A)).
If it isn't a rental activity, the automatic passive treatment never applies, and it's a trade or business instead. A business is only passive if you aren't really running it, and there's a specific test for that. Clear it and the loss is non passive, with no real estate professional status required.
Two details decide it:
It's the average stay across the tax year, not the shortest booking you took.
It's tested year by year, so a property that qualifies in 2026 can fail in 2027 if your booking mix shifts.
There's a second door at an average stay of 30 days or less, but only where "significant personal services" are provided by or on behalf of the owner (Temp. Treas. Reg. 1.469-1T(e)(3)(ii)(B)). Most owners can't use it, for a reason we'll come back to.
What are the three tests you have to pass?
Three gates, and the last one is the one that gets left out of the pitch.
Gate one, not a rental activity. Average stay of seven days or less, or the narrower 30 day path.
Gate two, material participation. Clear one of the tests in Temp. Treas. Reg. 1.469-5T(a).
Gate three, a loss you can actually use. Non passive gets the loss out of the passive bucket, but it doesn't mean the full amount lands on this year's return.
Gate three shows up in March, when every move that would have helped was available in June. The booking calendar, who does the cleaning, how the hours get recorded: all of it is decided during the year.
By the time a return is in front of someone, the big number on paper has already become a smaller number on the return.
What are the material participation rules for a short term rental?
The regulation gives seven tests, and two do most of the work.
The clean one is time. You participate "for more than 500 hours during such year" (Temp. Treas. Reg. 1.469-5T(a)(1)). On top of a clinical schedule, that's a stretch for almost everyone.
So most physicians aim at the 100 hour test instead, and it has two halves.
You participate "for more than 100 hours during the taxable year," and your participation is "not less than the participation in the activity of any other individual" (Temp. Treas. Reg. 1.469-5T(a)(3)). The regulation spells out that this includes people who own no interest at all.
That second clause is what quietly kills it. Not owners. Any individual.
Your cleaner counts, your co host counts, and your handyman counts.
Dr. Patel's cabin, and the cleaning service
Dr. Patel is a hospitalist working seven on, seven off. She buys a cabin and puts in 112 hours over the year on guest messaging, pricing, restocking, two furnishing trips, and coordinating repairs. She clears the 100 hour floor with room to spare.
Then add up the cleaning service.
Participant | Hours |
Dr. Patel | 112 |
Cleaning service (4 hours × 38 turnovers) | 152 |
100 hour floor | 100 |
One vendor beat her by 40 hours, and the test is gone. Her 112 hours were real and they weren't enough. That's a year zero problem with a year zero fix, and no fix at all by April.
Run that arithmetic before you buy. A cleaner at four hours a turnover passes 100 hours at 25 turnovers, which on a weekly booking property is the first half of the year. A property manager will beat anything you can do from a hospital.
So the design decision is really this. Keep the labor thin and keep the highest hour role on your own side of the ledger. Or accept that a full service manager puts the 100 hour test out of reach and leaves only the 500 hour path.
Nobody asks what your call schedule looks like before telling you 100 hours is easy. A surgeon with unpredictable call and a dermatologist finishing clinic at 5 aren't equally positioned to handle evening turnarounds.
Does a spouse's participation help?
Yes, and more than most owners expect. A spouse's hours count as yours, "without regard to whether the spouse owns an interest in the activity and without regard to whether the spouses file a joint return" (Temp. Treas. Reg. 1.469-5T(f)(3)).
For a household with one clinical calendar and one flexible one, that's often what makes the test reachable.
What about the other five tests?
They almost never help here:
Two of them look backward, so they do nothing for a property you just bought.
Substantially all participation gets harder with every person you pay.
Facts and circumstances is off the table entirely if you participate 100 hours or less (Temp. Treas. Reg. 1.469-5T(b)(2)(iii)).
More on which path fits which schedule is in The 100 Hour Material Participation Path.
What records do you actually need?
Less than the usual advice suggests. Participation "may be established by any reasonable means."
Contemporaneous daily logs "are not required if the extent of such participation may be established by other reasonable means" (Temp. Treas. Reg. 1.469-5T(f)(4)). Appointment books and calendars can do it.
But read the other half. You still have to establish the hours, and reconstructing a number from memory two years later, with nothing behind it, isn't a reasonable means.
Two categories of hours get thrown out no matter how well you document them:
Investor work doesn't count unless you're "directly involved in the day-to-day management or operations of the activity" (Temp. Treas. Reg. 1.469-5T(f)(2)(ii)). That rules out reviewing statements and building spreadsheets, which is the padding we see most often.
Work "not of a type that is customarily done by an owner of such an activity," where a principal purpose was avoiding the loss disallowance, is disregarded (Temp. Treas. Reg. 1.469-5T(f)(2)(i)).
This is also why the 30 day path rarely helps. Routine cleaning, trash collection, and ordinary repairs are "excluded services" for that test (Temp. Treas. Reg. 1.469-1T(e)(3)(iv)(B)(3)). The turnover work owners point to is exactly what the regulation excludes.
How much can you actually deduct?
Bonus depreciation is the engine here, and it's at 100% and permanent. The One Big Beautiful Bill Act amended section 168(k) to provide "a permanent 100 percent additional first year depreciation deduction." It reaches qualified property "acquired and placed in service" after January 19, 2025 (IRS Notice 2026-11, section 2.02(1)).
The trigger is the acquisition date rather than the placed in service date, which reverses the habit built during the phase down years. A written binding contract signed before January 20, 2025 keeps the property on the old schedule even if you closed later.
Here is the part the sales pitch skips. Qualified property means MACRS property with a recovery period of 20 years or less (26 U.S.C. 168(k)(2)(A)(i)(I)). Your building isn't that.
Component | Recovery period | Bonus eligible |
Land | None, never depreciates | No |
Building (residential rental) | 27.5 years, straight line | No |
Appliances, carpeting, furniture | 5 years | Yes |
Site improvements (paving, fencing) | 15 years | Yes |
Residential rental property runs 27.5 years straight line (IRS, Depreciation and Recapture). The IRS puts appliances, carpeting, and furniture in a residential rental activity in the 5 year class (Publication 527), and site improvements generally land in the 15 year class.
That's what a cost segregation study is doing. It's identifying the slice of the purchase that was never 27.5 year property to begin with.
So when you hear "100% bonus depreciation," hear 100% of a slice. How big that slice is depends entirely on the property, which is why anyone quoting you a percentage before looking at your building is guessing.
What limits the deduction even when you qualify?
This is gate three, and it's the one that gets left out.
Clearing the seven day test and the hours test makes the loss non passive. Section 461(l) then caps how much net business loss a non corporate taxpayer can deduct against other income in one year (26 U.S.C. 461(l)).
For tax years beginning in 2026 that cap is $256,000, or $512,000 on a joint return (Rev. Proc. 2025-32, section 4.31). That's down sharply from $313,000 and $626,000 in 2025, because OBBBA made the limitation permanent and reset the indexing to the original amounts.
The excess isn't lost. It carries forward as a net operating loss, but two things about that carryforward matter:
It doesn't help the year you were planning around.
An NOL can offset no more than 80% of taxable income in a later year, so even the carryforward arrives partly restrained.
Note also that employee wages sit outside the section 461(l) calculation, so your W-2 doesn't soak up the loss the way people assume.
Back to Dr. Patel
Say she fixes the hours problem, the property throws off a $700,000 first year loss, and she files jointly.
Item | Amount |
First year loss | $700,000 |
2026 joint threshold | $512,000 |
Deductible this year | $512,000 |
Carried forward as NOL | $188,000 |
Still real money, and not what the spreadsheet showed her in December. The $188,000 is also subject to the 80% limitation when she goes to use it.
Does your state follow the federal answer?
Often not, and this is where a federal deduction quietly stops existing.
A federal deduction doesn't automatically appear on the state return, and several states decouple from bonus depreciation specifically. We cover the same problem from the entity side in S Corp State Taxes for Physicians: CA, NY & NJ.
California
The clearest case. The Franchise Tax Board states plainly that "in general, California R&TC does not conform to the OBBBA" (2025 Personal Income Tax Booklet).
California has also long required its own depreciation figures. The recovery period or basis used for California "may be different from the recovery period or amount used for federal" (Schedule CA (540) instructions).
Your federal year one deduction does not exist on the California return.
California goes further than depreciation. The same instructions note that "California law does not conform to federal law for material participation in rental real estate activities." The participation analysis you just worked through is a federal answer rather than automatically a California one.
New York
New York decoupled from section 168(k) for personal income tax purposes, not only at the corporate level. Individuals filing Form IT-201 or IT-203 use Form IT-398 to compute a separate New York depreciation figure for section 168(k) property placed in service after May 31, 2003 (Form IT-398).
The instructions also direct that the modification be made for the full federal deduction even where the activity is subject to federal loss limitations. A capped federal deduction can still produce a full New York addback.
New Jersey
New Jersey's decoupling reaches the Gross Income Tax, which is the individual return. The Division of Taxation explains that 2004 legislation "revised and extended federal bonus depreciation decoupling" for both the Corporation Business Tax and the Gross Income Tax (NJ Division of Taxation). The gross income tax provision applies to tax years beginning on or after January 1, 2004.
Three states, three different mechanics, and none of them a copy of the federal answer. Raise your own state before you model the deduction, not after.
How much can you use it yourself?
Fewer days than most owners assume, and the counting is harsher than the headline.
Under section 280A, the property becomes a residence for the year once your personal use exceeds the greater of two figures. One is 14 days. The other is "10 percent of the number of days" the unit is rented at a fair rental (26 U.S.C. 280A(d)(1)).
Cross that line and the deduction limits tighten hard, which can undo the loss you built the plan around.
Three counting rules catch people:
Part of a day is a full day. The statute deems the unit used personally "for a day if, for any part of such day" it's used that way, so an afternoon stop counts the same as a week.
Family counts as you. Use by anyone with an interest in the unit, or by a family member under section 267(c)(4), is your personal use.
A cheap night isn't a rented night. A day isn't a fair rental day if the unit was used personally, so discounting a stay for a friend doesn't convert it.
Section 280A is the same section behind the Augusta rule, where 14 days works in your favor. Physicians who know Augusta often assume the vacation home math is just as friendly, and it isn't.
There's one real exception. A day you spend working substantially full time repairing and maintaining the property isn't a personal use day (Publication 527).
Note the words. Substantially full time, and repairs and maintenance. A weekend where you fix the deck in the morning and swim in the afternoon doesn't qualify, and improvements are a different category with a much murkier answer than repairs.
There's more to the day counting than fits here. See Personal Use of Rental Property and the 14 Day Rule.
What happens when you sell?
Accelerated depreciation is timing rather than forgiveness, and this is where the cost segregation decision comes back around.
Those 5 year and 15 year components are section 1245 property. When 1245 property sells at a gain, prior depreciation returns as ordinary income first, at your marginal rate.
The building follows a gentler path, but not a free one. Straight line depreciation usually produces no ordinary income recapture on the structure. The depreciation you claimed still comes back as unrecaptured section 1250 gain, taxed at a maximum 25% rate (IRS Topic no. 409).
Two consequences to weigh before you order a study:
If you take the deduction at your top ordinary rate and pay it back at that same rate years later, you've moved the tax rather than erased it. What you win is the use of the money in between, plus any rate difference between the two years, which is smaller and less certain than the year one deduction implies.
Depreciation is recaptured whether or not you claimed it, so skipping it doesn't protect you at sale.
Exit math is its own topic. See Depreciation Recapture on Rental Property.
Is it worth it for you?
Sometimes. It works best when the average stay sits under seven days without contortions and someone in the household can carry real hours.
Two more conditions matter just as much. You would want the property regardless of the tax treatment, and the loss is usable in the year you were planning around.
It works badly as a tax first purchase. Picture a property bought mainly for the deduction, run by a management company that logs more hours than you do, in a state that decouples. That combination produces a large paper loss and a small actual benefit.
The loophole isn't failing in that scenario. It's working exactly as written, and that pattern is one of the most common things we see when thousands of physicians bring us their prior returns.
The useful question isn't whether the mechanism is real. It's whether your own calendar and your own state let you clear all three gates, and that question has to be answered before the purchase rather than at filing.
