Short-Term Rental (“STR Loophole”): Quick Guide

• Local rules first: Verify that short-term rentals are permitted in the city, county, or HOA where you’re buying or converting a unit; some areas ban or cap STRs. We can introduce you to a trusted STR search partner who helps clients vet zoning and permitting if you’d like.
• Average guest stay ≤ 7 days (or ≤ 30 days if you provide hotel like “substantial services”).
• A caution on the second path: providing hotel-like services (daily cleaning, meals, concierge) can move the rental from Schedule E to Schedule C and add self-employment tax on the profits. Most clients should aim for the 7-day-average path and skip the extra services; talk to us before promising guests anything hotel-like.
• Structure bookings so the average stay meets that rule each year, and download booking reports (Airbnb/VRBO exports) as proof.

To treat the rental as non passive, you (or you and your spouse) must meet one of the following tests during the year you want to take the loss:

500-hour test:

• You must log more than 500 hours of work on the rental.

100 hour / most hours test:

• You must log more than 100 hours and more time than any other individual, including cleaners or co hosts.

Substantially all test:

• You must perform virtually all the work yourself.

You should keep a contemporaneous time log using a calendar, spreadsheet, or tracking app that includes the date, the activity, and the hours worked.

For material participation, the Regulations provide 7 tests, but above 3 tests are the most relevant in the context of short term rentals.

Additionally, if you own multiple short term rentals, there is an opportunity to make an election to group the properties together as a single activity for purposes of the material participation tests. By electing to group the properties as one activity, you can combine the hours spent across the multiple properties to satisfy the material participation test for this one activity.

The seven material participation tests are in Treasury Regulation 1.469-5T(a); the 7-day average-stay rule is in Regulation 1.469-1T(e)(3)(ii).

To qualify for the STR loophole, you need to materially participate in the rental activity, most commonly by meeting the 500-hour test or the 100-hour test (and more than anyone else). Not all time you spend on the property counts, so it's critical to understand which activities the IRS recognizes and which it doesn't.

Activities that generally count:

• Cleaning the property between guests, including laundering linens and restocking supplies
• Performing repairs and maintenance (fixing a leaky faucet, patching drywall, replacing a thermostat, painting, landscaping)
• Communicating with guests: responding to inquiries, sending check-in instructions, troubleshooting issues during their stay, handling complaints
• Managing bookings on platforms like Airbnb or VRBO (updating the calendar, adjusting nightly rates, responding to reviews)
• Marketing and advertising the property (taking and editing listing photos, writing or refreshing the listing description, running paid ads, posting on social media)
• Coordinating with vendors and contractors (scheduling the HVAC technician, meeting the cleaner, supervising repairs)
• Restocking consumables (coffee, toiletries, paper goods) and shopping for the property
• Performing periodic inspections and walkthroughs

• Investor-type activities: reviewing financial statements, analyzing performance reports, studying the market for future acquisitions, meeting with your CPA or attorney about the investment. The IRS specifically excludes these unless you're directly involved in day-to-day management.
• Travel time to and from the property: hours spent driving or flying to the rental are generally not counted toward material participation
• Education and research: reading books, taking courses, or attending seminars on short-term rentals
• Work not customarily done by an owner: if you hire a property manager and your only role is overseeing them at a high level, those hours likely don't qualify
• Time spent by your spouse on investor activities: though a spouse's qualifying participation does count toward your total

Practical Examples:

1. Counts: You spend three hours on a Saturday cleaning the property between guests, two hours that evening responding to booking inquiries and adjusting next month's rates, and another hour the following week meeting an electrician at the property to fix an outlet. All of that, six hours, counts.
2. Does not count: You spend two hours reviewing your QuickBooks to see how the property performed last quarter, an hour on a call with your CPA about whether to buy a second STR, and four hours driving to the property. None of that counts toward material participation, even though it relates to the rental.
3. Mixed: You drive two hours to the property (doesn't count), spend five hours doing maintenance and cleaning once you arrive (counts), and then drive two hours home (doesn't count). Only the five hours of on-site work qualifies.

We strongly recommend keeping a contemporaneous log: a calendar, spreadsheet, or app entry made at or near the time the work was performed, that records the date, the activity, and the time spent. The IRS has successfully challenged taxpayers who relied on after-the-fact reconstructions, even when they clearly performed the work.

Even if you meet the material participation test, personal use of the property can severely limit or eliminate your ability to claim losses. Under §280A, a dwelling unit is treated as a personal residence, and subject to the vacation home loss limitation rules, if your personal use during the year exceeds the greater of:

• 14 days, or
• 10% of the days the property was rented at fair market value

If that threshold is crossed, your deductions are capped at your rental income, meaning no net loss can be claimed against your other income, which defeats the entire purpose of the STR strategy.

What counts as a personal use day:

• Any day you, your spouse, or your children use the property for personal purposes, even just one night
• Days used by other family members (parents, siblings, in-laws, grandchildren) - unless they pay full fair market rent and use it as their principal residence
• Days the property is rented to anyone, including friends, extended family, or strangers for less than fair market value
• Days used by anyone under a reciprocal use arrangement (e.g., a home-swap)
• Days donated to a charity auction and used by the winning bidder

What does NOT count as a personal use day:

• Days you're at the property principally to perform repairs or maintenance, even if family members are present (the work has to be the primary purpose, and we recommend documenting this carefully)
• Days the property is vacant and available to rent
• Days the property is rented at fair market value to an unrelated third party

Examples:

• Safe: The property is rented 180 days during the year. You and your family stay there for 14 nights over the summer. Personal use (14) does not exceed the greater of 14 days or 18 days (10% of 180), so the §280A limitation does not apply.
• Problematic: The property is rented 100 days during the year. You and your family stay there for 15 nights. Personal use (15) exceeds the greater of 14 days or 10 days (10% of 100), so the property is treated as a personal residence and your loss is suspended.
• Hidden trap: The property is rented 200 days at FMV, and you let your sister and her family stay for a week at a discounted "family rate." That week counts as personal use because she didn't pay full FMV, even though you weren't there.
• Repair day: You spend a long weekend at the property installing new flooring and painting two bedrooms. Your spouse is there but isn't doing the work. If your principal purpose was the renovation, those days are not personal use days, but keep receipts, photos, and a written log of what was done.

Personal use & expense allocation

Even if your personal use stays under the §280A threshold (the greater of 14 days or 10% of rental days), any personal-use day still requires you to allocate expenses between personal and rental use. You can still claim a loss (assuming you're under the §280A limits and meet the STR participation rules above), but the deductible portion will be reduced proportionally. This is why we'll ask you to track and report personal-use days when we prepare your return.

The 14-day / 10% personal-use limit is Section 280A(d).

• If you want to front load depreciation, we can connect you with a cost segregation partner who handles the study; the shorter-life property it identifies generally qualifies for 100% bonus depreciation, now permanent for property acquired after January 19, 2025.
• Because the activity is non passive, the resulting paper loss can offset W2 wages, 1099 income, or other business profits in the same tax year.
• We’ll report the rental on Schedule E with a statement noting STR status and your material-participation test.
