Short-Term Rental Taxes: The Rules Vacation Rental Owners Get Wrong

A cabin in the pines or a casita near the red rocks can be a solid source of income, and short-term rental taxes follow a different set of rules than a long-term rental. Whether the property belongs on Schedule E or Schedule C, whether its income is passive or nonpassive, and whether a cost segregation study is worth the fee all turn on facts about how you run it. Get those facts right and the return follows. Get them wrong and you can pay tax you did not owe, or lose a deduction you had earned.

Here is how the rules work, including when cost segregation makes sense and when it does not.

Schedule E or Schedule C?

A short-term rental with basic services belongs on Schedule E. Cleaning between guests, fresh linens, Wi-Fi, utilities, and a welcome basket are all considered services that come with the property rather than services to the guest. Income on Schedule E is not subject to self-employment tax.

Schedule C applies when you provide substantial services to guests during their stay: daily housekeeping, meals, guided outings, concierge-style help. At that point the IRS treats you like a hotel and the income picks up self-employment tax. Occasional extras, such as a recommendation list or a bottle of wine on arrival, do not cross that line.

The seven-day rule and material participation

Under the passive loss rules, a property whose average guest stay is seven days or less is not treated as a rental activity at all. That single fact is the basis of what is often called the short-term rental loophole. If you also materially participate, meaning you meet one of the IRS hours tests, the property's losses are nonpassive and can offset wages, business income, or retirement distributions in the same year.

The three tests owners most often use: more than 500 hours in the year; more than 100 hours and more than any other person; or substantially all of the work on the property. The catch is that your cleaner's, handyman's, and property manager's hours count against you in the second test. Owners who hand everything to a management company often do not qualify, and owners who do qualify need a log kept during the year, not reconstructed in April.

The seven-day rule cuts both ways

Nonpassive treatment is only an advantage in a loss year, which for most owners means the year of purchase or the year of a cost segregation study. Once the property is profitable after expenses and depreciation, and a well-run rental should be, the same rule works against you in one respect: that profit is nonpassive income, so it cannot be offset by passive losses from your other rentals or investments, and it does not count as passive income that would free up losses suspended from prior years.

Two things it does not do. Nonpassive income on Schedule E is still not subject to self-employment tax; that only happens with substantial services on Schedule C. And income from a rental business you actively run is generally outside the 3.8% net investment income tax, which passive rental income is not. For retirees, rental profit does raise modified adjusted gross income, which affects the phase-out of the $6,000 senior deduction and Medicare premium surcharges. A profitable property is a good problem, but it belongs in the plan.

Cost segregation: what it is and when it makes sense

A building is normally depreciated slowly, over 27.5 years for a residential rental and 39 years for property used on a transient basis, which is where many short-term rentals land. A cost segregation study breaks the purchase price into its parts. Land is never depreciable. The structure stays on the long schedule. But appliances, flooring, cabinetry, window coverings, the hot tub, the deck, landscaping, and site work are separately identified as 5-, 7-, or 15-year property.

That matters because 100% bonus depreciation is now permanent for property acquired after January 19, 2025. Anything the study assigns to those shorter lives can be deducted in full in the first year. For a furnished vacation rental, the reclassified share can be meaningful, because so much of what makes the property rentable is not the four walls.

A deduction that size in year one usually produces a loss on the property. Whether that loss helps you depends entirely on the section above. If you materially participate in a seven-day-or-less rental, or you qualify as a real estate professional, the loss can offset your other income. If the property is passive, the loss sits suspended and the study accomplished very little this year.

Four more things to weigh before ordering a study:

• Recapture. When you sell, depreciation on the short-life property is taxed as ordinary income and depreciation on the building at up to 25%. A cost segregation study is a timing strategy, not a permanent one, unless you later use a 1031 exchange or hold the property until it receives a step-up in basis.
• Holding period. The math works best when you expect to own the property for several years. A study on a property you sell in two years mostly moves tax from one year to the next.
• Cost and quality. An engineering-based study on a residential property often costs a few thousand dollars. Inexpensive online estimates exist, and they carry more risk if the return is examined.
• Prior-year purchases. A study can be done years after you bought the property. The missed depreciation is caught up in the current year through a change in accounting method on Form 3115, with no amended returns.

If you are weighing a study, the order matters: run the numbers on your own return first, including whether you can use the loss, and only then order the study. We can do that analysis and connect you with cost segregation resources for an engineering-based study when it makes sense.

Arizona transaction privilege tax and local rules

Short stays are taxed as transient lodging in Arizona, which means state, county, and city transaction privilege tax on every booking. When you list through an online marketplace registered with the Arizona Department of Revenue, the platform collects and remits that tax for bookings made through it. Two things still fall on you: an Arizona TPT license, and the tax on any direct bookings, repeat guests, or friends of friends who pay you outside the platform.

Flagstaff and Sedona both regulate short-term rentals separately, with local licensing, neighbor notification, and a state liability insurance requirement. The specifics change, so confirm the current rules with each city before you list rather than after a complaint.

When you sell

Every dollar of depreciation, including the bonus depreciation from a cost segregation study, is recaptured when the property sells. Owners who are tired of managing turnovers have three exits to compare: sell and pay the tax, exchange into a less demanding property or a passive real estate interest through a 1031, or keep the property and let it pass to heirs with a stepped-up basis, which we explain in How Inherited Assets Are Taxed. Gifting the property to children during your lifetime is different: your basis and the recapture go with it, a tradeoff covered in our gifting guide. If the rental is part of a larger business, the same allocation logic we covered in Selling Your Business: The Tax Decisions to Make Before the Buyer Shows Up applies.

Expenses that are easy to overlook

Depreciation gets the attention. The everyday expenses are where deductions quietly go missing. A few that are easy to overlook:

• Platform and payment fees. Host fees are netted out of your payouts. Report the gross rent the platform reports to the IRS, then deduct the fees, so the two match.
• Mileage and travel to the property for turnovers, repairs, and meetings with your cleaner, at the standard mileage rate or actual cost, with a log.
• Guest consumables: coffee, toiletries, paper goods, propane, firewood, and welcome items.
• Furnishings, linens, and small appliances, which can often be deducted in the year of purchase under the de minimis safe harbor rather than depreciated.
• Technology and subscriptions: pricing tools, smart locks, noise monitors, and the business share of your phone and internet.
• Taxes, licenses, and permits: transaction privilege tax you paid, city licensing, and the state-required liability coverage.
• Refunds, damage claims, and deposits. Refunds reduce income, and a security deposit is not income until you keep it.
• Costs before the first guest, which are startup costs with their own rules rather than ordinary expenses.

Records that hold up

• An hours log kept during the year, with dates and what you did, for every material participation claim.
• A calendar showing rental days, personal days, and days spent on repairs, which do not count as personal use.
• A separate bank account and card for the property, so nothing personal lands on Schedule E.
• The cost segregation study itself, and the closing statement it was built from.
