Cost Segregation for
Airbnb & Short-Term Rentals
Cost segregation is the IRS-approved strategy that lets Airbnb, VRBO, and short-term rental hosts accelerate depreciation and dramatically reduce their tax bill. With the STR loophole, you may be able to offset your W-2 income too.
Why Cost Segregation Is Especially Powerful for STR Owners
Short-term rentals unlock tax advantages that long-term rentals can't touch.
The STR Tax Loophole
Short-term rentals with average stays of 7 days or less are not treated as rental activity under IRS rules. With material participation, your depreciation deductions can offset W-2 and business income — not just rental income.
Furnished = Bigger Deductions
Furniture, appliances, decor, and electronics in your STR are all separately depreciable assets on 5- and 7-year schedules. Furnished rentals typically see 25–30% of the property reclassified to shorter lives.
100% Bonus Depreciation in 2026
Property acquired after January 20, 2025 qualifies for 100% first-year bonus depreciation on reclassified assets. Combined with cost segregation, this means massive year-one deductions.

Airbnb Cost Segregation FAQ
Common questions from short-term rental owners.
What is cost segregation for Airbnb and short-term rentals?
Cost segregation is an IRS-recognized engineering analysis that reclassifies parts of your rental property into shorter depreciation schedules (5, 7, and 15 years instead of 27.5). For STRs, this includes furniture, appliances, flooring, cabinetry, landscaping, and more — resulting in significantly larger first-year tax deductions.
What is the STR loophole?
If your average guest stay is 7 days or less and you materially participate in the rental, the IRS does not classify it as passive rental activity. This means depreciation from cost segregation can offset your W-2 and business income, not just rental income — a significant tax advantage unique to short-term rentals.
How much can I save with cost segregation on my Airbnb?
Savings depend on purchase price, furnishing level, and tax bracket. A furnished $500K STR in the 37% bracket typically sees $30,000–$55,000 in first-year write-offs and $10,000–$20,000 in cash tax savings. Use our free instant estimate tool to see your specific numbers.
I bought my Airbnb years ago. Can I still do cost segregation?
Yes. A look-back study provides the data your CPA needs to file IRS Form 3115 and claim all the missed accelerated depreciation as a catch-up deduction on this year's return — without amending prior returns. Learn more in our look-back study guide.
Does VRBO qualify for cost segregation?
Yes. Cost segregation applies to the property itself regardless of which platform you list on. Airbnb, VRBO, Booking.com, and direct bookings all qualify.
Do I need a site visit?
No. RentalWriteOff completes every study remotely using photos, public records, and satellite imagery. No appointments, no scheduling hassle. Reports are delivered in 2 business days.
