The STR Loophole: How to Offset W-2 Income with Short-Term Rental Depreciation

Most rental property investors accept that their losses are passive — meaning those losses can only offset other passive income, not a W-2 paycheck. The short-term rental exception is one of the few places in the tax code where that assumption does not hold. If your property qualifies, depreciation losses from an Airbnb or VRBO can offset earned income dollar for dollar.

This strategy is sometimes called the STR loophole, though it is not a loophole in any pejorative sense. It is a straightforward application of two sections of the tax code, confirmed by Treasury regulations that have been on the books since 1987. The IRS knows about it. Your CPA should know about it. The question is whether your specific situation satisfies both parts of the test.

Here is what the test requires, what it takes to document it, and how to think about whether it applies to you. Run any specific conclusions past your tax preparer before you act on them.

Why Normal Rental Losses Are Passive

IRC Section 469 established the passive activity loss rules in 1986. Under those rules, losses from rental activities are passive by default — regardless of how active you are in managing the property. A landlord who answers every maintenance call personally still has passive rental losses, because Congress decided to classify rental activity as passive as a matter of law.

Passive losses can only offset passive income. They cannot offset wages, salaries, business income, or self-employment income. They accumulate and carry forward until you either generate passive income or sell the property, at which point the suspended losses are released.

The short-term rental exception carves out a specific category of rental property from this passive classification. Understanding why requires a brief look at how the code defines a “rental activity.”

Part One: The Seven-Day Test

Treasury Regulation 1.469-1T(e)(3)(ii)(A) provides that a rental activity is not classified as a rental activity for purposes of Section 469 if the average period of customer use is seven days or less.

Read that slowly. If your average guest stay is seven days or less, your STR is not a rental activity under the passive activity rules. It is treated more like a hotel or inn — an active business activity. That removes the passive-by-default classification entirely.

Calculating your average stay: divide the total days of guest use during the year by the total number of rentals. If you had 180 guest nights across 40 separate reservations, your average stay is 4.5 days. That satisfies the seven-day test.

Most Airbnb and VRBO properties satisfy this easily — the platforms are built around short stays. Three-night minimums, weekend bookings, and holiday stays all produce averages well below seven days. Where you might run into issues is a beach house with two-week summer rentals that skew the average upward. Pull your booking history and calculate the number before assuming you qualify.

Part Two: Material Participation

Satisfying the seven-day test removes the passive classification, but it does not automatically make the activity non-passive for you personally. For losses to offset your W-2 income, you must also materially participate in the STR activity during the tax year.

Treasury Regulation 1.469-5T provides seven tests for material participation. You need to satisfy at least one. For most STR owners, the most accessible test is this: you participated in the activity for more than 100 hours during the year, and your participation was not less than that of any other individual.

That second part matters. If you hired a co-host or property manager who spent more time managing the property than you did, you may not satisfy this test even if you logged 150 hours yourself. The requirement is that you did more than anyone else.

The most reliable test, if you can satisfy it, is simply 500+ hours per year. That is about 10 hours per week of documented STR-related activity. Qualifying activities include guest communication, calendar management, cleaning coordination, maintenance oversight, marketing, purchasing supplies, and bookkeeping. Passive monitoring — checking your app to see how many bookings are coming in — does not count.

Documentation: What Your CPA Will Need

The IRS does not prescribe a specific format for material participation records, but the expectation is clear: your records should be contemporaneous (created at the time of the activity) and specific (showing the date, the activity, and the time spent).

A shared Google Calendar or a simple spreadsheet works well. Log each activity with a date, a brief description, and a duration. Guest check-in coordination on the morning of a checkout: 45 minutes. Responding to 12 guest messages: 30 minutes. Running to the property to fix a plumbing issue: 2 hours. These are the kinds of entries that hold up.

Your CPA needs this log before they file your return. They also need your average stay calculation — total guest nights divided by total bookings. If you have not already pulled your booking history from your platform, do it now and keep it. Platforms do not always make historical data easy to retrieve after the fact.

Where Bonus Depreciation Fits In

The STR exception determines whether your losses are passive or non-passive. Bonus depreciation under IRC Section 168(k) determines how large those losses can be in Year 1.

The One Big Beautiful Budget Act, signed into law in July 2025, restored 100% bonus depreciation for property placed in service after January 19, 2025. For STR investors, this means that 5-year and 15-year MACRS property identified in a cost segregation study — furniture, appliances, electronics, land improvements — can be fully expensed in the year they are placed in service.

The combination looks like this in practice: a cost segregation study on a $700,000 STR identifies $175,000 in 5-year and 15-year property. At 100% bonus depreciation, that is a $175,000 deduction in Year 1. If you qualify under the STR exception, those losses can offset your W-2 income. At a 37% marginal rate, the tax impact is $64,750. Your CPA confirms the numbers and files the election on Form 4562. You get the documentation in order before the filing deadline.

A few things worth knowing: the bonus depreciation election is made on a per-asset-class basis and is generally irrevocable once filed. Your CPA may recommend a different approach in certain situations — for example, if you expect to be in a higher bracket in future years, or if the passive loss rules limit your current-year benefit. Talk through the election decision with your tax preparer before assuming 100% bonus is always optimal.

Common Situations Where This Does Not Work

Worth being direct about the cases where the strategy fails, because the failure can be expensive.

Full-service property management. If you use a property manager who handles everything — guest communications, check-ins, cleaning, maintenance — and that manager spends more hours on the property than you do, you likely cannot satisfy the material participation test. You can fix this going forward, but you cannot retroactively claim hours you did not spend.

Long-term or medium-term rentals mixed in. If some of your stays are 30+ days, those days may pull your average above seven. The calculation is across all rentals, not just the short ones.

Rental income well below DSCR threshold. This is a tax strategy issue rather than a qualification issue, but worth noting. If the property does not produce meaningful income, the cost of the documentation and the professional fees may outweigh the tax benefit at your bracket. Run the numbers with your CPA before commissioning the study.

Suspended losses from prior years. If you have passive losses from prior years on this property, they will be released when you sell — not converted retroactively into active losses. The STR exception only applies going forward from when you begin qualifying.
