7 Tax Deductions Short-Term Rental Owners Routinely Overlook Most short-term rental owners think Airbnb is rental income with extra cleaning fees. The tax code disagrees, and the disagreement is worth real money. The IRS treats short-term rentals differently from long-term rentals — different enough that the strategies that work for one are wrong for the other. Owners who run their STR like a vacation home pay tax like one. Owners who treat it like a business and document it that way unlock deductions most landlords never see. Here are seven that get left on the table. 1. The short-term rental loophole that can offset ordinary income This is the big one, and most owners have never heard the name. When the average rental period is seven days or less and the owner materially participates in operating the property, the activity is generally not treated as a rental for passive activity purposes under Treas. Reg. §1.469-1T(e)(3)(ii). Translation: losses from the property can offset W-2 or business income, not just other passive income. That's the gap between "I have a paper loss I can't use" and "I just sheltered $40,000 of my consulting income." Material participation isn't a vibe — it's seven specific tests under §469. The two that STR owners hit most often: more than 500 hours in the activity for the year, or more than 100 hours and more time than anyone else. Without a time log, none of this is defensible. 2. A cost segregation study that front-loads depreciation A residential property normally depreciates over 27.5 years. A cost segregation study breaks the building into components and reclassifies the pieces that don't actually last 27.5 years — appliances, flooring, cabinetry, landscaping, certain electrical and plumbing — into 5-, 7-, and 15-year recovery periods. Property with a recovery period of 20 years or less is eligible for bonus depreciation. Under the One Big Beautiful Bill Act, 100% bonus depreciation was made permanent for qualifying property acquired and placed in service after January 19, 2025 (IRS Notice 2026-11). On a $600K STR with $480K allocable to the building, a study reclassifying 25% into short-life property — about $120K — can produce a year-one bonus depreciation deduction of that full amount. Paired with the STR loophole above, that deduction can flow against ordinary income. The math gets serious quickly. 3. The de minimis safe harbor on furnishing and setup costs When you buy a property to put on Airbnb, you spend tens of thousands of dollars on furniture, linens, dishware, decor, smart locks, and the kind of mid-century...
