Can Your Airbnb Losses
Offset Your W-2 Income?

Most rental losses are passive — they can only offset other passive income. But short-term rentals have a special exception. Use this worksheet to see if you qualify.

The IRS treats rentals with an average stay under 7 days as non-passive activities under Reg. 1.469-1T(e)(3)(ii). If you materially participate, losses can offset W-2/1099 income — no Real Estate Professional Status required.

Step 1
Do You Qualify? (All three must be YES)
Average guest stay under 7 days
Check your booking platform. If your average stay is under 7 days, your rental is automatically classified as a non-passive activity by the IRS.
You materially participate (100+ hours/year)
Guest communication, cleaning coordination, maintenance, pricing adjustments, turnover management, listing optimization. Most active Airbnb hosts clear 100 hours easily.
Hours on this property exceed hours by anyone you hire
You must spend more hours than any single person you pay (not total — per person). If you have a co-host doing 80 hours and you do 101, you qualify.
Step 2
Estimate Your Offset

B Rental income (annual) $65,000 _________
C Operating expenses ($35,000) _________
D Standard depreciation (line B basis / 27.5) ($21,818) _________
E Net rental income before cost seg (B+C+D) $8,182 _________
F Additional Year 1 deduction from cost seg ($130,000) _________
G Net rental loss after cost seg (E+F) ($121,818) _________
H Taxable W-2 income after offset (A+G) $128,182 _________
I Estimated tax savings at 37% — (A−H) × 0.37 $45,073 _________

Important Notes
What you need to know before filing
  1. This only works for STRs (avg stay < 7 days). Long-term rentals are passive unless you have Real Estate Professional Status.
  2. Material participation is per-property. You need 100+ hours on each STR you want to use this strategy for.
  3. Cost segregation accelerates depreciation timing — total lifetime depreciation is unchanged. When you sell, depreciation recapture applies (Section 1250).
  4. These are estimated tax savings. Actual results depend on your specific tax situation, state taxes, and deductions.
  5. 100% bonus depreciation is permanent under the One Big Beautiful Bill Act (2025). No more sunset dates.
