What Is the Short-Term Rental Tax Loophole?
A plain-language explanation of the strategy: what it is, why it is legal, how it cuts the tax on a salary, and who it actually fits.
The short answer
The short-term rental tax loophole is a legal strategy that lets a high-income earner use depreciation from a short-term rental to cut the tax owed on a W-2 salary or other active income. It works because a rental with an average guest stay of seven days or fewer is not treated as passive under the tax code, so the paper loss from depreciation can offset a salary, which a normal long-term rental cannot do.
That definition hides a lot of detail, and the detail is where owners win or lose the strategy. This page covers what the loophole is, why it exists, how the money actually moves, and who it fits. For the rules that decide whether you qualify, the material participation page goes deeper. To see the dollar figures on your own purchase, the calculator does the math.

Why it is called a loophole
Nothing about it is hidden or aggressive. The strategy reads straight from the Internal Revenue Code: Section 469 on passive losses and Section 168(k) on bonus depreciation. The IRS has defended both in tax court. It earns the "loophole" label only because most owners never meet the requirements that open it, so the people who do can offset a six-figure salary while a neighbor with a similar rental cannot. The advantage is real. The secrecy is not.
How it works, in plain terms
Four moves stack to turn a property purchase into a deduction against your salary.
- 1Separate land from building. Land never depreciates, so only the building counts.
- 2Run a cost segregation study. It reclassifies 20 to 30% of the building into 5, 7, and 15-year property instead of the standard 27.5-year schedule.
- 3Apply 100% bonus depreciation to that reclassified portion, writing it off in year one rather than spreading it over decades.
- 4Offset your income. If two rules are met, that first-year paper loss lands against your active income and cuts your tax.
On a $750,000 property, that can mean a first-year deduction over $160,000. The calculator shows what it looks like on your numbers, and the methodology page shows where every figure comes from.
The two rules that decide if you qualify
The fourth move is the one that fails for almost everyone, because a rental loss is passive by default and a passive loss cannot touch a salary. Two rules make the loss non-passive, and you need both.
The seven-day test. When your average guest stay is seven days or fewer, the property stops counting as a passive rental activity. That single fact is why a short-term rental owner does not need Real Estate Professional Status or its 750-hour bar.
Material participation. You then have to be involved enough in running the property to clear one of the IRS tests, usually more than 100 hours and more than anyone else who works on it. This is where a full-service manager quietly disqualifies most owners, because the manager out-hours the owner. The material participation page covers the tests, the hours that count, and the manager trap in full.
Why it matters now
Bonus depreciation is the engine that makes the first-year number large, and it just got more valuable. The One Big Beautiful Bill Act, signed in 2025, restored 100% bonus depreciation under Section 168(k) on a permanent basis for property acquired on or after January 20, 2025, and IRS Notice 2026-11 removed the old placed-in-service deadline. For a buyer today, the strategy is the most favorable it has been in years, because the full reclassified amount comes off your income in year one instead of phasing down.
Who it fits, and who it does not
It fits
- A high earner taxed in the 32% bracket or above.
- Someone willing to be hands-on, or with a spouse who will be.
- A property that runs on guest stays of a week or less.
It does not fit
- A passive investor who wants a manager to handle everything.
- A low tax bracket, where the deduction is worth little.
- A long-term rental, which never opens the seven-day test.
