Short-term rental taxes and the "STR loophole," explained

Who it fits

Two kinds of hosts get the most out of these rules. The first is a W-2 earner who hosts on short-term rental platforms and wants to understand how the income, and any losses, interact with a salary. The second is a host scaling from one property toward a small portfolio, often two to ten doors, sometimes across state lines. The firm also works with syndicators and funds.

How the income is taxed, generally

Most short-term rental income goes on Schedule E with the property's expenses and depreciation. If you provide substantial services primarily for guests' convenience, such as regular cleaning, changing linen, or maid service, the IRS says the income goes on Schedule C, and self-employment tax may apply. Whether the year shows a profit or a paper loss depends on rates, occupancy, expenses, and financing.

The seven-day question

The rule most hosts ask about is the average period of customer use. You figure it by dividing the total days in all rental periods by the number of rentals in the year. When the average is 7 days or less, the property is not a rental activity under the passive loss rules. An average of 30 days or less also qualifies if you provide significant personal services with the stays. Either way, material participation then decides whether losses are passive.

Nothing here is automatic. Personal use days, the actual stay averages, and your participation all feed the answer, and the records decide.

How hosts materially participate

You need to meet one of the seven material participation tests for the property. Three come up most for hosts:

• More than 500 hours on the property during the year.
• Your work was substantially all of the work on it, counting everyone.
• More than 100 hours, and no other individual put in more.

Everyone's hours count in those comparisons, including cleaners, co-hosts, and handymen who own no part of the property. A paid property manager makes it harder: under the facts-and-circumstances test, your management time does not count if someone else is paid to manage. Your spouse's participation counts toward yours.

Active participation is not material participation

The two sound alike and work differently. Active participation is the lower bar for the up-to-$25,000 allowance on ordinary long-term rentals: you own at least 10% and make management decisions such as approving tenants or setting rents. That allowance phases out as income rises and is generally gone at $150,000 of modified adjusted gross income.

Material participation is the stricter standard the short-term rental rule depends on. It means meeting one of the seven tests, such as more than 100 hours with no one putting in more. Approving a cleaner’s schedule from a distance does not get there.

Personal use

If you use the property personally for more than the greater of 14 days or 10% of the days it is rented at a fair price, the IRS treats it as a home you also rent out, and your deductible rental expenses can be limited. If you use it as a home and rent it fewer than 15 days in the year, you do not report the rent and do not deduct rental expenses. Count personal days carefully, including days family stays.

Pairing with cost segregation

Furniture and appliances in a furnished rental are 5-year property, and land improvements are 15-year. For property acquired after January 19, 2025, those can qualify for 100% bonus depreciation in year one, which is often where a short-term rental's paper loss comes from. Depreciation taken now generally comes back as taxable gain when you sell. Our cost segregation page covers how that works and its catches.

The STR loophole or REPS: which one you need

Both can turn rental losses into losses that offset wages. They get there differently.

Some households use both: the short-term rental rule for a vacation property and REPS for a spouse who runs the long-term portfolio. Our REPS guide covers that side.

An example

A W-2 earner buys a furnished short-term rental. Guests stay 3.5 nights on average. The owner logs 160 hours handling bookings, guest messages, and turnovers; the cleaner logs 110 hours; there is no property manager. That meets the more-than-100-hours test with no one putting in more. If a cost segregation study creates a paper loss for the year, that loss is generally non-passive and can offset wages. Other limits can still apply, and the figures are illustrative.

What to log

Keep a simple record as the year goes. The IRS accepts any reasonable method, such as an appointment book, calendar, or narrative summary. For each entry, note:

• The date and the property.
• What you did: guest messages, booking changes, turnovers, restocking, repairs, listing updates.
• Roughly how long it took.
• Who else worked on the property that week and about how long, since the 100-hour test compares your time with theirs.

Keep each stay's check-in and check-out dates from the platform too. They are what the 7-day average is built from.

Local rules are separate

Cities, counties, and states can have their own short-term rental registration, permit, and occupancy or lodging tax rules. Those sit outside the federal income tax rules on this page, so check where your property is.

How Bellamy approaches it

It starts with a free 15-minute intro call with Corben. When the facts warrant it, a planning session, $1,500, about 60 minutes recorded, maps your platform summaries, stay lengths, and participation against the rules before the year closes. Prep covers the returns themselves from $650, with the video review before anything is signed. When a deeper look is justified, cost segregation coordination runs as a specific project, scoped on a call.

What does not work

Assuming every short-term rental loss deducts. Mixing personal use into the averages without counting it. Deciding the property qualifies because a software dashboard said so.

The treatment follows the facts. The hosts who benefit are the ones whose records were kept while the year was open.
