Does the Short-Term Rental Loophole Still Work in 2026? (OBBBA Update)

Yes — the short-term rental loophole still works in 2026, and the One Big Beautiful Bill Act (OBBBA) did not change the core mechanics. Bonus depreciation under IRS §168(k) remains at 100% for qualifying property placed in service this year. The 7-day average stay rule that classifies short-term rentals as active income — not passive — is untouched. Material participation requirements are identical. If you have been running the numbers on a short-term rental and wondering whether recent legislation killed the strategy, the answer is no.

What the OBBBA did do is make several provisions permanent that were previously set to expire or phase down. For STR investors that is good news: instead of watching bonus depreciation erode under a sunset schedule, you now have legislative certainty heading into future acquisitions. This article breaks down exactly what changed, what stayed the same, and how to calculate your Year 1 deduction on a specific property.

What Is the STR Loophole, and Why Does It Still Exist?

The short-term rental "loophole" is the intersection of two separate tax provisions that, when combined, produce an unusually powerful Year 1 deduction for active investors.

Provision 1 — The STR exception to passive activity rules (IRC §469): Under normal real estate rules, rental income and losses are classified as passive. Passive losses can only offset passive income — not your W-2 salary, business income, or other active earnings. But there is an exception: if the average guest stay at your property is 7 days or fewer, the IRS does not classify the activity as rental income at all. It is treated more like an active business. That single classification difference opens the door to offsetting ordinary income.

Provision 2 — Bonus depreciation under IRS §168(k): Normally, a building is depreciated over 27.5 years (residential) or 39 years (commercial). But certain components of a property — personal property like appliances, flooring, and cabinetry (5-year class), and land improvements like pools, patios, and landscaping (15-year class) — qualify for 100% bonus depreciation in the year placed in service. A proper cost segregation analysis identifies exactly how much of your purchase price falls into these accelerated categories.

When you combine these two provisions, an active STR investor can generate a paper loss in Year 1 — sometimes $100,000 to $250,000 or more on a mid-range property — and use it to offset W-2 or business income dollar for dollar. That is the loophole. And as of 2026, both legs of it remain intact.

What the OBBBA Changed vs. What Stayed the Same

The One Big Beautiful Bill Act touched a wide range of tax provisions. Here is the breakdown as it specifically relates to short-term rental investors:

The short version: nothing in the OBBBA eliminated, restricted, or narrowed the STR loophole. The legislation largely extended and made permanent provisions that were favorable to business owners and investors. The political risk that lawmakers might specifically target the STR exception — which has been discussed in various policy circles — did not materialize in this bill.

The 7-Day Rule Explained

The most important qualifying condition for the STR loophole is average guest stay. Under IRC §469(c)(2), a rental activity is not treated as passive if the average period of customer use is 7 days or fewer. This is calculated across all rentals for the year — not per-guest but as a weighted average.

Here is how the math works: if you had 40 bookings totaling 180 rental nights during the year, your average stay is 180 ÷ 40 = 4.5 days. That clears the 7-day threshold. If you have a mix of short and longer stays — for instance, you allowed a few 10-day bookings — those longer stays raise your average and could push you over the limit.

Material Participation: The 100-Hour Test and Others

Meeting the 7-day rule only gets you halfway there. You must also materially participate in the STR activity. The IRS defines material participation through seven alternative tests — you only need to satisfy one of them:

1. 500-hour test: You personally participated in the activity for more than 500 hours during the year. This is the gold standard and hardest to dispute.
2. Substantially all test: Your participation was substantially all of the participation by any individual (you did essentially everything).
3. 100-hour test: You participated more than 100 hours and no other individual participated more than you. This is the most common test used by STR investors who self-manage.
4. Significant participation test: Your participation exceeded 100 hours across multiple activities, and total across all activities exceeds 500 hours.
5. Five-of-ten-year test: You materially participated in 5 of the last 10 taxable years.
6. Personal service test: The activity is a personal service activity and you materially participated in any 3 prior years.
7. Facts and circumstances test: You participated more than 100 hours and, based on all facts and circumstances, participated on a regular, continuous, and substantial basis.

For most self-managing STR investors, the 100-hour test (Test 3) is the most accessible. If you handle guest communications, cleaning coordination, maintenance calls, and check-in management yourself — without a full-service property manager doing more — you can typically meet this standard. The critical word is "more than you." If your property manager logs more hours than you do, the test fails.

State Conformity: Where the Loophole Gets Complicated

Federal bonus depreciation applies in all 50 states — but only at the federal tax level. Many states have decoupled from §168(k), which means your state return treats the property as if bonus depreciation does not exist. You must add back the federal bonus amount on your state return and depreciate on the normal state schedule.

This is an especially important consideration for California-based investors who own STRs in California. You get the federal deduction but no state benefit — and California has a 9.3%–13.3% marginal rate, so that is a meaningful gap. Compare that to an investor buying in Tennessee or Florida: full federal deduction plus a state with no income tax, making the total effective savings substantially higher.

Real Example: $850,000 STR in a Conforming State

Here is how the numbers work on a specific property — an $850,000 cabin-style short-term rental in a state that fully conforms to federal bonus depreciation:

At 18% bonus-eligible — which is a realistic midrange figure for a fully-furnished STR with outdoor amenities — an $850,000 property generates $153,000 in Year 1 deductions. At a 37% marginal rate, that translates to $56,610 in federal tax savings in the first year of ownership. That is real money returned to you from taxes you would otherwise have paid on your salary or business income.

Properties with pools, hot tubs, outdoor kitchens, and high-end interior finishes routinely hit 22–26% bonus-eligible. Properties with minimal outdoor amenities, older construction, and basic interiors typically land in the 14–18% range. The spread is wide — which is why identifying the bonus potential before you make an offer matters.

What Can Still Kill the Deduction

The OBBBA preserved the loophole, but these four factors still disqualify it:

1. Average stay drifts above 7 days

This is the single most common disqualifier. A few long bookings, a slow shoulder season with multi-week stays, or switching platforms mid-year can push your average above the threshold. Monitor your booking data quarterly, not annually.

2. You fail material participation

Using a full-service property manager who handles everything — communications, cleaning, maintenance, check-ins — makes it very difficult to demonstrate the required hours of personal involvement. If you are hands-off by design, you likely do not materially participate, and the losses are passive.

3. High land value ratio

You can only depreciate improvements — not land. A beachfront property where land represents 60–70% of value has a much smaller depreciable basis, which directly limits your bonus-eligible deduction. A $1M property with 65% land value has only $350,000 in improvements to depreciate. Even at 25% bonus-eligible, that is $87,500 — much less than the same $1M purchase in a market with 20% land value, where improvements are $800,000 and the deduction could be $200,000+.

4. Investing in a non-conforming state without understanding the state-level impact

Your federal deduction is safe regardless. But if you were counting on state tax savings to complete your underwriting, owning in California or New York without accounting for the state add-back can produce unexpected state tax bills.

How to Screen Properties Before You Buy

The most common mistake STR investors make is running the bonus depreciation math after closing, once they have already committed to the price and terms. By then, there is nothing to negotiate. The property is what it is.

Smart STR investors run the depreciation estimate before the offer. They know going in whether they are looking at a 15% or a 24% bonus-eligible property, and they factor that into the effective acquisition cost. A $950,000 property with a 24% bonus-eligible ratio produces $228,000 in Year 1 deductions — at 37%, that is $84,360 in savings that effectively reduces your all-in cost to $865,640. That changes the underwriting, and it changes what you should be willing to pay.
