Three rules, in order, turn a normally‑passive rental loss into one you can apply against your paycheck. Miss any one and the chain breaks.
This is the path the IRS walks to decide whether your depreciation loss can offset active income. Each step is a gate — not a scoring system.
If your average guest stay is 7 days or less, the IRS stops treating the property as a rental activity under Section 469. It becomes a business.
Clear any one of seven tests. The three most Airbnb hosts use:
An engineering study splits your property into component classes, moving 20–35% into 5, 7, and 15‑year lives. Combined with bonus depreciation, this creates the year‑one loss you can now legally deduct.
A $150,000 depreciation loss is the same number on paper. But whether you can use it this year depends entirely on whether you cleared the three gates above.
Without the chain, the loss sits in passive suspense — it carries forward, waiting for passive income to offset. With the chain, it hits your 1040 this April.
| Scenario | Where the loss goes |
|---|---|
| Long‑term rental stays > 7 days |
Passive — suspended |
| STR, no material participation outsourced to PM |
Passive — suspended |
| STR + material participation self‑managed Airbnb |
Active — offsets W‑2 |
Meet Jordan. Software engineer, $200K W‑2 income, bought a $650K cabin in Gatlinburg in March. Runs it on Airbnb with a 4.3‑day average stay, handles bookings and cleaning coordination herself. Here's the year‑one math.
| W‑2 income | $200,000 |
| Straight‑line depreciation (27.5yr) | −$18,900 |
| STR net income | +$8,400 |
| Taxable income | $189,500 |
| Federal tax @ 32% marginal | ~$40,500 |
| W‑2 income | $200,000 |
| STR net income (before depreciation) | +$27,300 |
| Reclassified components (28% of $520K basis) | $145,600 |
| Year‑1 depreciation (bonus + MACRS) | −$177,300 |
| Taxable income | $50,000 |
| Federal tax @ effective rate | ~$5,700 |
Jordan's study cost $795. Her W‑2 withholding refund is 40× that in a single April.
Illustrative example assuming 60% bonus depreciation rate, 80% of purchase price allocated to basis (20% to land), 28% component reclassification, and a single filer in the 32% marginal bracket. Your CPA will model with actual numbers.
Outsourcing to a full‑service PM usually kills material participation — they spend more hours on the property than you do, and the "more than anyone else" test fails. Self‑management or a hybrid is the path.
Cost seg depreciation is prorated by month. A late‑December close means fractional year‑one deduction. If you're timing for tax, close earlier or accept a bigger year‑two hit.
Selling the property recaptures depreciation at up to 25%. A 1031 exchange into a like‑kind property defers it. Plan the exit before you plan the study.
Bonus rates stepped down through 2026 and have moved around with recent legislation. Lock in your study year with a CPA — don't assume last year's rate applies.
