Short-Term Rental Tax Strategy: How the STR Rules Work

The short-term rental tax strategy is a chain of four rules, and each link has to hold: an average stay of 7 days or less, material participation, depreciation large enough to matter (cost segregation and bonus depreciation), and personal use, reporting and recapture rules that do not undo the result. This guide walks the chain in that order.

The 7-day rule: why a short-term rental is not a rental activity

IRC 469(c)(2) makes every rental activity passive. The regulations then define rental activity, and Treas. Reg. 1.469-1T(e)(3)(ii) lists six exceptions. The first two are the ones short-term rental owners use:

• (A) the average period of customer use for the property is seven days or less; or
• (B) the average period is 30 days or less and significant personal services are provided by or on behalf of the owner in connection with making the property available.

An activity that meets either exception is not a rental activity. The Form 8582 instructions then tell you what it is: you determine whether the rental is a trade or business activity and, if so, whether you materially participated. If you did, the income or loss goes on the forms normally used and is nonpassive. If you did not, it is a passive trade or business activity and the loss is suspended, with no access to the $25,000 rental real estate allowance, because the activity is not rental real estate. Real estate professional status, covered in the real estate professional status guide, is never reached: it only matters for activities that are rental activities.

Significant personal services under exception (B) exclude services needed for lawful use, repairs that extend the property's life, and services common to long-term rentals such as cleaning common areas, routine repairs, trash collection and security (Treas. Reg. 1.469-1T(e)(3)(iv)). A property with 10-day average stays qualifies only with services well beyond a turnover clean.

How to compute the average period of customer use

Treas. Reg. 1.469-1(e)(3)(iii) divides the total days in all periods of customer use (counting periods that end during the year or include its last day) by the number of those periods. A property rented for 240 nights across 60 stays has an average of 4 days and qualifies. Sixty stays totaling 480 nights averages 8 days and does not. A period of customer use is each continuous or recurring right to use the property, whether or not the guest shows up every night. If the activity holds more than one class of property, each class is weighted by its share of gross rental income. The computation is annual, so a property that drifts toward monthly winter tenants can fall out of the exception.

Material participation: the tests that matter for a short-term rental

Treas. Reg. 1.469-5T(a) sets seven tests; meeting any one is enough. Four matter for a property owner:

The hours must be real work: guest communication, pricing, turnovers you do yourself, repairs, restocking, listing management. Treas. Reg. 1.469-5T(f)(2)(ii) excludes work done as an investor, such as reviewing financial statements or monitoring the finances in a non-managerial capacity, unless you are directly involved in day-to-day management. Under 1.469-5T(f)(4), hours can be shown by any reasonable means, including calendars and narrative summaries, but a log kept during the year is the evidence that survives an audit.

Front-loading deductions: cost segregation and bonus depreciation

Nonpassive treatment is worth little without a loss, and depreciation is what creates one. A cost segregation study separates the parts of a property that are 5-, 7- and 15-year property (appliances, carpet, furniture, land improvements) from the building, and bonus depreciation at 100% applies to that reclassified property when it is acquired after January 19, 2025. The building shell still depreciates straight line over 27.5 years as residential rental property, or 39 years if it is not. That last point needs a check: IRC 168(e)(2)(A) excludes from the definition of dwelling unit “a unit in a hotel, motel, or other establishment more than one-half of the units in which are used on a transient basis.” Whether a single short-term rental home falls in that exclusion is a question to settle with your preparer before assuming 27.5 years.

Personal use: the 14-day and 10% rules of IRC 280A

A short-term rental is a dwelling unit, and IRC 280A watches personal use. Under 280A(d)(1), you use the unit as a residence in a year if personal use days exceed the greater of 14 days or 10% of the days it is rented at a fair rental. Cross that line and the deductions attributable to rental use are limited to the rental income, which eliminates the loss. Personal use includes use by family members and by anyone paying less than fair rent (280A(d)(2)); a day spent working substantially full time on repairs and maintenance is not personal use. Publication 527 walks through the day count and the expense split. The mirror image is 280A(g): a unit used as a residence and rented fewer than 15 days in the year produces no taxable rent and no rental deductions at all.

Schedule C or Schedule E, and self-employment tax

Passing the 7-day exception does not by itself move the property to Schedule C. The Schedule E instructions keep rental real estate on Schedule E even when it is a trade or business, and send it to Schedule C only if you “provided significant services to the renter, such as maid service.” Furnishing heat and light, cleaning public areas and trash collection do not count. Publication 527 gives regular cleaning, changing linen and maid service as examples of substantial services and warns that self-employment tax may then apply. The statute behind that is IRC 1402(a)(1), which excludes rentals from real estate from self-employment income unless received as a real estate dealer. A turnover clean between guests is the ordinary case; hotel-style daily service is the exception.

Recapture when you sell

The front-loaded deductions come back at sale. The Form 4562 instructions state that gain on property that took a special depreciation allowance is generally recaptured as ordinary income up to the depreciation previously allowed, including the allowance, which is the IRC 1245 rule for the reclassified 5-, 7- and 15-year property. Straight-line depreciation on the building itself comes back as unrecaptured section 1250 gain, which Publication 544 describes as the part of the gain due to depreciation and IRC 1(h)(1)(E) taxes at 25%. A property bought in 2026 with a $105,910 first-year deduction and sold in 2029 will carry most of that deduction back into income, at ordinary rates for the personal property portion. The strategy defers tax; it does not erase it.
