Most rental losses are stuck. The IRS calls them passive. That means they can only offset other passive income, not your salary or business profit. So a big cost-seg deduction on a normal rental might just sit and wait.
The short-term rental exception changes that. If your rental is short-term and you are active in running it, the losses are not passive. They can offset your regular income, like your W-2 paycheck or your business profit. And you do not need to be a real estate professional.
Why it matters: pair this with a cost segregation study and you can create a large first-year deduction that lowers the tax on your day-job income. That is the heart of the exception.
Step one: the 7-day rule
Your rental must not be a normal long-term rental. To qualify, the average stay of your guests must be 7 days or less. Think of a vacation home, cabin, or beach condo you rent on a nightly basis.
There is a second version too: if the average stay is 30 days or less and you provide hotel-like services, it can also qualify. But the simple, common path is the 7-day average.
Step two: material participation
Meeting the 7-day rule is not enough by itself. You also have to be the one doing the work. The IRS calls this material participation. You can meet it several ways. The most common are:
- You work 100 hours on the rental during the year, and no one else works more than you.
- You work 500 hours on the rental during the year.
- You do substantially all the work on the rental yourself.
The work counts: guest messaging, booking, cleaning coordination, repairs, supply runs, and bookkeeping. Keep a simple log of your hours and what you did. That log is your proof if the IRS ever asks.
You do not need real estate professional status
This is the key point. To unlock losses on a normal long-term rental, you usually need to be a real estate professional. That takes 750+ hours and more than half your work time in real estate. It is hard to hit if you have a regular job.
The short-term rental path skips that test. You only need the 7-day average plus material participation. That makes it reachable for busy professionals who own one or two vacation rentals.
The 7-day average, plus real participation. No real estate professional status needed.
How cost segregation supercharges it
A cost segregation study finds the short-life parts in your rental: furniture, appliances, fixtures, landscaping, and more. With 100% bonus depreciation now permanent under the OBBBA law, you can deduct those parts in full in year one.
On a furnished vacation rental, those parts add up fast. The result can be a large first-year loss. Because the exception makes that loss non-passive, it can lower the tax on your other income. Learn how a study works.
