Short-Term Rental Airbnb Tax Write-Off Calculator
Short-term rentals (average stay ≤7 days) qualify as non-passive activity under IRC §469. With material participation, you can deduct losses against ordinary W-2 income — a major tax advantage over traditional long-term rentals.

The STR Loophole — §469 Exception
Under IRC §469, rental real estate is passive activity by default. Losses cannot offset W-2 ordinary income unless you qualify as a real estate professional (REP, 750+ hours/year). Most W-2 employees can't qualify.
Short-term rentals (average guest stay 7 days or less) are excluded from the §469 rental definition under Reg 1.469-1T(e)(3)(ii)(A). They're treated as a non-passive trade or business. With material participation, losses offset W-2 income — no REP status needed.

Material Participation Tests
Material participation requires one of these tests: (1) 500+ hours during the year, (2) substantially all participation (you and immediate family do all work), (3) 100+ hours AND more than any other individual, or (4) significant participation activity at 100+ hours when combined with other activities totaling 500+ hours.
Most STR owners use test (3): manage 100+ hours yourself AND more hours than your cleaner or property manager. Log everything: cleaning, guest communication, restocking, repairs, marketing time, financial tracking. A contemporaneous time log is required for IRS audit defense.
Bonus Depreciation + Cost Segregation
Cost segregation breaks the building basis into 5-year (personal property), 15-year (land improvements), and 27.5-year (building structure) buckets. The 5-year and 15-year buckets qualify for bonus depreciation — accelerated write-off in year 1.
Bonus depreciation rate in 2026 is 40% (TCJA phase-down: 100% pre-2023, 80% 2023, 60% 2024, 40% 2025-2026, 20% 2027). On a $400K building with 25% allocated to 5-year property, that's $100K × 40% = $40K bonus depreciation year 1, plus standard 27.5-year depreciation on the remaining $300K basis.

When the Loophole Doesn't Apply
Loophole fails if: average stay exceeds 7 days (use Schedule E as passive rental, no W-2 offset), you can't prove material participation, or the IRS reclassifies your activity as personal use (must be ≤14 days personal use OR ≤10% of rental days, whichever is greater).
If you mix personal and rental use, you can only deduct expenses pro-rated to rental days. Track personal vs rental days carefully. See our vacation rental ROI calculator.
