The Tax Angle & STR Loophole

Get a CPA

This is the most fact-specific, highest-stakes section in the report — and the one most likely to change with your situation. Treat it as a map of the terrain, not advice. Engage a CPA who does short-term-rental tax before acting.

The floor: the 14-day “Augusta” rule

Rent the home fewer than 15 days/year and the income is tax-free and unreported. Irrelevant for a real rental, but it’s the bottom of the ladder. HIGH

The ordinary deductions (Schedule E)

Once it’s a real rental, you deduct mortgage interest, property tax, insurance, management fees, utilities, repairs, and depreciation against rental income. Standard stuff. HIGH

The prize: the short-term-rental loophole

This is the one investors chase. Two conditions unlock it:

1. Average guest stay ≤ 7 days. Under Reg. §1.469-1T(e)(3)(ii), such an activity is not a “rental” for passive-loss purposes — it’s a trade or business. OBX’s Saturday-to-Saturday 7-night week qualifies (7 ≤ 7 — right on the line, so document it).
2. Material participation. Meet any one test: 500+ hours; or 100+ hours and more than anyone else; or you do substantially all the work.

Clear both, and the property’s losses become non-passive — they can offset your W-2 / agency / K-1 income — without needing Real Estate Professional status. HIGH

The engine: depreciation + bonus + cost seg

• A qualifying STR (≤7-day avg) is nonresidential property → depreciated over 39 years (not the 27.5 residential schedule). A cost, but the trade for non-passive treatment.
• The One Big Beautiful Bill Act (signed July 4, 2025) permanently restored 100% bonus depreciation for assets acquired after Jan 19, 2025 — so in 2026, 100% bonus is live. HIGH
• A cost-segregation study reclassifies components (fixtures, land improvements, the pool) into 5/7/15-year buckets that qualify for 100% bonus — front-loading large first-year deductions. Vendor illustrations: a $500k–$600k STR can generate $60k–$150k+ in first-year deductions (deal-specific; needs an engineered study).

That first-year deduction, offsetting ordinary income at your marginal rate, is the real return on many of these deals — often worth more than the cash flow.

The trap: the loophole and your vacation collide

The prize runs through material participation — but the vacation-home mixed-use rule disallows losses if personal use > 14 days or 10% of rented days (whichever is greater). And a full-service PM doing all the work undermines your material-participation claim. So the loophole realistically requires:

minimal personal use + you doing genuine, logged work (self- or co-manage, own the booking/maintenance decisions).

You cannot simultaneously (a) vacation there often, (b) hand it fully to Twiddy, and (c) claim the W-2 offset. Pick the goal — business, shelter, or lifestyle. This is the tax code’s version of the same trade-off that runs through the whole report. HIGH
