How Short-Term Rentals Affect Your Taxes (2026 Guide)

Income Reporting: Schedule C vs. Schedule E

Short-term rental income is reported differently depending on the services you provide. If you offer 'substantial services' to guests (daily cleaning, concierge, meals, guided tours), the IRS treats your STR as a business, and income goes on Schedule C (IRC §1402). You will owe self-employment tax (15.3% on the first $168,600 in 2026, 2.9% above that), but you also gain access to the Section 199A QBI deduction (20% of qualified business income). If you do not provide substantial services (most Airbnb hosts), income is reported on Schedule E as rental income. Schedule E income is not subject to self-employment tax, but it is also not considered 'earned income' for retirement contribution purposes. The classification matters: it affects your self-employment tax liability, retirement contribution eligibility, and which deductions you can claim.

Deductible Expenses for STR Owners

STR operators can deduct all ordinary and necessary expenses related to the rental activity (IRC §162 for Schedule C; IRC §212 for Schedule E). Common deductions include: mortgage interest (allocated to rental use), property taxes (allocated to rental use), insurance premiums, utilities, cleaning and turnover costs, property management fees, platform service fees (Airbnb/VRBO), supplies and amenities, repairs and maintenance, professional photography, and advertising costs. If you use the property personally, you must allocate expenses between personal and rental use based on the number of days used for each purpose (IRC §280A). The 14-day rule under IRC §280A(g) provides a safe harbor: if you rent the property for fewer than 15 days per year, the rental income is tax-free and you do not need to report it. However, you also cannot deduct rental expenses beyond mortgage interest and property taxes you would normally claim on Schedule A.

Depreciation: Your Largest Non-Cash Deduction

Depreciation is typically the largest single deduction for STR owners, yet it requires no out-of-pocket expense. Residential rental property depreciates over 27.5 years using the straight-line method under MACRS (IRC §168). For a $750K property (with $150K allocated to land, which is not depreciable), your annual depreciation deduction is approximately $21,818. This is a non-cash expense that reduces your taxable income without affecting your bank account. Depreciation is mandatory. The IRS requires you to claim it (or will assume you did when you sell, reducing your cost basis regardless). When you sell the property, depreciation recapture is taxed at a maximum rate of 25% under IRC §1250. Even so, the time value of the deductions taken over the holding period almost always outweighs the recapture tax at sale.

Cost Segregation: Accelerating Depreciation

A cost segregation study reclassifies property components into shorter depreciation categories. Instead of depreciating everything over 27.5 years, a cost seg study identifies assets that qualify for 5-year (appliances, carpeting, decorative fixtures), 7-year (furniture, office equipment), and 15-year (landscaping, driveways, fencing) recovery periods. For a $750K STR, a cost seg study might reclassify $150K-$200K into these shorter categories. With 100% bonus depreciation restored under OBBBA for property placed in service after January 20, 2025, you can deduct the entire reclassified amount in year one. On a $750K property, this could generate $150,000-$200,000 in first-year depreciation, compared to $21,818 under straight-line. At a 37% federal marginal rate, the accelerated deduction saves $55,500-$74,000 in year-one federal taxes. Cost seg studies typically cost $5,000-$15,000 for residential properties and pay for themselves many times over.

Material Participation and the Passive Activity Rules

This is where STR tax strategy gets powerful, and nuanced. Under IRC §469, rental activities are generally classified as 'passive,' meaning losses can only offset passive income, not your W-2 or active business income. However, short-term rentals with an average guest stay of 7 days or fewer are exempt from the automatic passive classification under Reg. §1.469-1T(e)(3)(ii)(A). This means your STR is treated as a non-passive activity if you materially participate. Material participation requires meeting one of seven tests under Reg. §1.469-5T. The most common for STR owners: (1) you spend more than 500 hours per year on the activity, (2) you spend more than 100 hours and no one else spends more, or (3) your participation constitutes substantially all of the participation. If you materially participate in a STR with average stays under 7 days, the losses generated by depreciation and cost segregation can offset your W-2 income, 1099 income, and other active income. This is the mechanism that allows a tech executive earning $400K to use $80K in STR depreciation losses to reduce their taxable income to $320K.

Passive vs. Non-Passive: Why It Matters

The passive vs. non-passive distinction is the single most important classification in STR tax planning. If your STR is passive, your depreciation-generated losses sit in a 'suspended loss' bucket and can only offset passive income (other rental income, limited partnership income, etc.) or be released when you sell the property. There is a $25,000 special allowance for active participation in rental real estate (IRC §469(i)), but it phases out completely at $150,000 MAGI, well below most high earners. If your STR is non-passive (average stay under 7 days + material participation), those same losses offset any income type. For a high earner generating $80K in STR losses through cost segregation, the difference between passive and non-passive classification is $80,000 × 37% = $29,600 in federal taxes. Maintaining contemporaneous time logs documenting your hours is essential. The IRS scrutinizes material participation claims in audit.

Bonus Depreciation Under OBBBA (2026 Rules)

The One Big Beautiful Bill Act restored 100% bonus depreciation for qualified property placed in service after January 20, 2025. This reverses the phase-down schedule that had reduced bonus depreciation to 80% (2023), 60% (2024), and 40% (2025). For STR owners in 2026, this means cost segregation reclassified assets qualify for full first-year expensing. Land improvements (15-year property) like landscaping, driveways, and sidewalks also qualify for bonus depreciation. The restoration applies to new and used property (a change originally introduced by the 2017 Tax Cuts and Jobs Act). This makes 2026 an unusually favorable year to purchase a STR and conduct a cost segregation study, as the full deduction is available regardless of when during the year the property is placed in service.

State Tax Considerations

State tax treatment of STR income varies significantly. California does not conform to federal bonus depreciation. CA taxpayers must add back the bonus depreciation difference on their state return, though federal savings are unaffected. States like Texas, Florida, Nevada, and Washington have no state income tax, making STR deductions purely a federal benefit. New York generally conforms to federal depreciation rules but has its own AMT calculations. Many states also impose occupancy taxes or transient lodging taxes on short-term rentals that are separate from income tax. Some municipalities require STR permits or licenses with associated fees. Always model both your federal and state tax impact when evaluating an STR investment. A property in a no-income-tax state generates the cleanest tax benefit.
