The strategy people call the “STR loophole”

The four pieces that make it work

It is not one rule; it is four that line up. Miss any of them and the strategy does not hold.

1. 01

   The seven-day rule

   If the average guest stay across the year is seven days or fewer, the activity is not a 'rental activity' under §469. That is what removes the passive label that normally blocks rental losses from touching active income.

2. 02

   Material participation

   You still have to materially participate. The common tests: more than 500 hours on the activity in the year, or more than 100 hours and more than anyone else involved. This is where a contemporaneous log matters, because it is the first thing an examiner asks for.

3. 03

   Cost segregation sizes the loss

   A furnished short-term rental is finish-heavy, so a study typically reclassifies 25% to 35% of the basis into 5-, 7-, and 15-year property that takes 100% bonus depreciation. That is what turns a modest paper loss into one large enough to offset a real W-2.

4. 04

   No REPS required

   This is the difference that makes it work for busy high earners. Real Estate Professional Status needs 750 hours and real estate as your main job, which most W-2 earners cannot meet. The short-term rental path does not require it at all.

This is not tax advice. The seven-day and material-participation tests are specific, and the deduction needs a defensible engineered study behind it. Your CPA confirms the position for your facts before you rely on it.

Who this fits

The short-term rental path is built for the earner who cannot become a full-time landlord but can genuinely run one property well.

• High W-2 earners without REPS. Physicians, engineers, attorneys, and tech employees who cannot meet the 750-hour test but can materially participate in a single short-term rental.
• Owners of a finish-heavy rental. A furnished property reclassifies the most, so the first-year loss a study produces is largest exactly where this strategy is used.
• People who want it done right. The strategy is only as good as its documentation and its study. It rewards an engineered, defensible approach and punishes a guess.

Common questions

What is the short-term rental tax strategy?

What the internet calls the 'STR loophole' is not a loophole. It is §469(c)(7) working the way Congress wrote it. A rental with an average guest stay of seven days or fewer is not a passive rental activity under the tax code, so if you materially participate in it, its losses are non-passive and can offset active income like a W-2, with no Real Estate Professional Status required. Cost segregation is the piece that makes those losses large, accelerating depreciation on a furnished rental's components into the first year. Structured correctly and documented, it is one of the few strategies that lets a high W-2 earner offset active income with real estate.

Is the 'STR loophole' real, and is it legal?

It is real, and it is not a loophole. The strategy is §469(c)(7) working as written: a rental with an average stay of seven days or fewer is not a passive rental activity, so materially participating in it makes its losses non-passive. It is an intentional part of the tax code, used as designed. What makes it defensible is doing it correctly: meeting the seven-day and material-participation tests and backing the deduction with a real engineered study.

How does the seven-day rule let me offset W-2 income?

Rental losses are normally passive and cannot offset a W-2. But under the regulations, a rental with an average guest stay of seven days or fewer is not treated as a rental activity, so it escapes the automatic passive label. If you then materially participate, the losses are non-passive and can reduce active income, including your W-2, in that year.

Do I need Real Estate Professional Status for a short-term rental?

No, and that is the point of this path. REPS requires more than 750 hours and real estate as your primary occupation, which a full-time professional usually cannot meet. The short-term rental route relies on material participation in the rental itself, not REPS, which is why it works for high W-2 earners who cannot become full-time landlords.

How much of a short-term rental can cost segregation accelerate?

On a furnished short-term rental, an engineered study commonly reclassifies 25% to 35% of the depreciable basis into 5-, 7-, and 15-year property, because these properties are heavy on finishes, appliances, and furnishings. Those components take 100% bonus depreciation, which is what makes the first-year loss large. The exact share depends on the property, which is why it takes a real study, not a rule of thumb.

What are the trade-offs I should plan for?

Recapture on sale, up to 25% on the real-property portion under §1250; smaller deductions in later years because you pulled them forward; and the requirement that your participation hours be real and documented. The strategy is defensible when the property makes sense on its own and the tests are genuinely met. Your CPA confirms all of it before you rely on any figure.
