[![Picture of Mire Group Marketing](https://www.mire.group/hs-fs/hubfs/MireIconOnly.png?width=30&name=MireIconOnly.png) Mire Group Marketing](https://www.mire.group/blog/author/mire-group-marketing) : Oct 20, 2026, 10:26:55 AM ![short term rental](https://www.mire.group/hubfs/MireGroup-Hero-STR-Loophole.png) The short-term rental loophole lets a loss from a rental offset your W-2 or business income when two things are true. Your average guest stay is seven days or less, and you materially participate in the rental. Pair that with a cost segregation study, and a property that makes money in real life can show a big loss on paper. Miss either test, or sell too soon, and it can work against you. I’m Marcus Mire, CPA and founder of MireGroup CPAs in Lafayette, Louisiana. Somebody asked me for the common pitfalls with short-term rentals that nobody talks about. Lots of people ask me about this. They just don’t ask me online. So here’s what a short-term rental is, and the ways it can derail you if you don’t follow the rules. ![MireGroup-Hero-STR-Loophole](https://www.mire.group/hs-fs/hubfs/MireGroup-Hero-STR-Loophole.png?width=1200&height=630&name=MireGroup-Hero-STR-Loophole.png) ## **What makes a rental “short-term” for taxes?** Generally speaking, it’s real estate you rent for seven days or less on average. Think a beach house. Something in the mountains. A cabin in the woods. Short stays. ## **Why does seven days or less matter?** Rental property in the tax world is normally passive. When something is passive, you can only take its losses against passive income. So if your rental produces a lot of paper losses from depreciation, you really can’t take that loss unless you have other passive income to offset it, or you sell the property. When you rent seven days or less on average, the property is no longer passive by nature. It’s treated more like a trade or business. And that’s important, because those losses can offset your W-2 or business income. That’s what everybody is looking for, right? Something in the tax code that produces a loss they can use against their active income. If the active and passive buckets are new to you, start with [Can Real Estate Losses Offset Your W-2 or Business Income?](https://www.mire.group/blog/can-real-estate-losses-offset-your-w-2-or-business-income) ## **What is material participation?** This is the second requirement, and it’s the one that’s often overlooked and really trips people up. You have to materially participate in the short-term rental. Section 469 of the tax code has a seven-factor test for it. Like everything in the tax code, it’s hard to boil down. But effectively, you have to work in the property. And it’s harder to meet than most people think. So it’s a two-prong test. You have to meet the seven days or less, and then you have to materially participate. If you don’t materially participate, you’ve really done nothing. You’re back in the passive rules, and the loss only offsets passive income. The tests are worth knowing about, because they decide whether any of this works. ## **Can you use a property manager and still qualify?** There are caveats where a property manager wouldn’t disqualify you. But generally speaking, if you have other people doing the work for you, it’s hard to materially participate. Here’s a rule of thumb. If you have a property manager, you probably don’t materially participate. The manager is likely doing more work on the property than you are, and the hours other people put in count against you. ## **How do you prove material participation?** Hours and logs are your friend. A contemporaneous log, meaning one you keep as you go, is the standard. It’s the same principle as proving mileage for auto deductions. If you can’t show the hours, you can’t defend the position. The best firms I know doing real estate work won’t even take you on as a client without material participation proof in the form of contemporaneous records. Records you kept as you went. You didn’t piece them together looking back. Be cautious of a CPA who will take your word for it that you materially participate. The firms that know real estate best make you go get a time log before they sign off. That’s what makes the position defensible if you’re ever audited. ## **How does a cost segregation study create the paper loss?** A short-term rental is considered commercial property in the tax world, so you’d normally depreciate the building over 39 years. That’s slow. A cost segregation study speeds it up. An engineering firm looks at your property and finds the pieces that can be written off faster. Flooring, light fixtures, appliances. Those shorter-life pieces can qualify for bonus depreciation, which can let you take all of that depreciation in the first year. Here’s the example I use. Say you buy a $1,000,000 condo at the beach. You rent it for $60,000 a year and net about $20,000 after taxes, interest, HOA dues and your other expenses. Typically a study finds 20% to 30% of the property you can write off in year one. Split the difference at 25%, and that’s $250,000 of depreciation. | | **Amount** | | --- | --- | | Net rental income | $20,000 | | Year-one depreciation with a cost seg | -$250,000 | | Result on paper | -$230,000 loss |   A property that made money in real life lost $230,000 on paper. That’s what everybody’s talking about when they say the short-term rental loophole. I walk through the full math, including the version without a study, in [Is a Cost Segregation Study Worth It on a Short-Term Rental?](https://www.mire.group/blog/is-a-cost-segregation-study-worth-it-on-a-short-term-rental) ## **What happens when you sell?** This is the one a lot of people forget. In that example, you took $250,000 of depreciation, so your basis in the property is now $750,000. (I’m leaving out the depreciation on the rest of the building. Just work with me here.) Sell it for $900,000, even less than you bought it for, and you still have a $150,000 gain. That’s called depreciation recapture. You’ve already enjoyed $250,000 of that cost basis in the form of depreciation deductions. Properties generally don’t go down in value. They normally appreciate. So if you sell shortly after the cost seg, you’re going to give that depreciation right back as income. Those are the two biggest traps I see. People don’t materially participate, or don’t document it properly. And they don’t understand depreciation recapture when they sell. ## **How do you know if the advice you’re getting is solid?** Look. If somebody is telling you to do a cost segregation study on a short-term rental, and they’re not asking how you’ll document an average stay of seven days or less, or how you’ll prove nearly 100% that you materially participate, I would not take that advice. That’s an aggressive position, and it’s going to be hard to defend in an audit. If someone is pitching it as easy, it’s less likely to work than they’re letting on. ## **Is the short-term rental loophole worth it?** It can be. If you’re a high earner feeling crushed by taxes, real estate could be the thing that helps you offset some of that income. Structured properly, with the records to back it up, it holds up. But at MireGroup we talk a lot about return on hassle. Make tax moves that are also good business moves. We don’t do things strictly for taxes, especially things that create other things you have to do, monitor and check. A short-term rental with a cost seg comes with all of that. A log to keep. An average stay to track. A recapture bill waiting if you sell. Sometimes the return’s not worth it. Depreciation should be a sweetener to a deal that already makes sense. Buying a property mostly for the write-off is letting the tax tail wag the business dog, and it’s one of the [tax planning mistakes that cost small business owners](https://www.mire.group/blog/2-tax-planning-mistakes-that-cost-small-business-owners). So here’s my takeaway. Short-term rental, with a cost seg to supercharge the deductions? Great. Materially participate and document it well. And watch out for depreciation recapture on a sale. ## **Frequently asked questions** **How could I have a gain on something I sold for less than I bought it for?** Because you’ve already enjoyed part of your cost in the form of depreciation deductions, and that brought your basis down. Take $250,000 of depreciation on a $1,000,000 property and your basis is $750,000. Sell for $900,000 and you have a $150,000 gain. **Does every stay have to be seven days or less?** No. The test is seven days or less on average. That average is something you need to be able to document. **Why do short-term rentals depreciate over 39 years?** In the tax world, a short-term rental is considered commercial property, so the building is written off over 39 years. That’s slow, which is why people turn to a cost segregation study to accelerate it. **Should I do a cost segregation study if I plan to sell in a few years?** Be careful. If you sell shortly after the study, you’re going to give much of that depreciation right back as income, because properties normally appreciate. Run the numbers on the sale before you pay for the study.   Thinking about a short-term rental, or already own one?
