OBBBA + The Short-Term Rental Loophole: How High Earners Now Offset Six- and Seven-Figure W-2 Income

Combine OBBBA's permanent 100% bonus depreciation with the short-term rental loophole, and you have one of the most powerful active-income offsets in the tax code.

Before OBBBA, the short-term rental (STR) loophole + cost segregation combo was already one of the most aggressive — and entirely legal — strategies a high-W-2 earner could deploy. With OBBBA's permanent restoration of 100% bonus depreciation, the impact just got reset to its TCJA-era maximum.

Refresher: what is the STR loophole?

Under IRC §469, rental real estate is generally treated as a 'passive activity' — losses can only offset passive income, not W-2 or business income. But there's an exception: if the average guest stay at your property is 7 days or less, it's not classified as a 'rental activity' under §469.

Combine that with material participation (typically 100+ hours/year and more than anyone else, OR 500+ hours/year), and the losses your STR generates are non-passive — they can offset W-2 income, business income, and any other active income source.

How OBBBA supercharges the strategy

Cost segregation on an STR property typically reclassifies 25–35% of the depreciable basis into short-life property. With 100% bonus depreciation restored, all of that reclassified amount becomes a year-one deduction.

Example: $1.5M STR portfolio, placed in service in 2025

  • Depreciable basis (80% of $1.5M): $1,200,000
  • Reclassified to 5/7/15-year property (~30%): $360,000
  • Year-one bonus deduction at 100% (OBBBA): $360,000
  • If you qualify for material participation: $360,000 of non-passive loss against your W-2 / active income
  • At a 37% federal + 5% state combined rate: $151,200 of direct tax savings, year one
Under the pre-OBBBA 40% rate, the same property would have produced only $60,480 in tax savings. OBBBA is a 2.5x multiplier on this exact playbook.

Common pitfalls

  • Average stay over 7 days — even by a single day on average — kills the loophole. Track this religiously.
  • Material participation is harder than people think. The 100-hour rule requires both the hour threshold AND more hours than anyone else (including cleaners, co-hosts, property managers).
  • Cost segregation in year of acquisition is essential — bonus depreciation only applies in the year placed in service.
  • Real estate professional status (REPS) is a different, harder-to-qualify path. Don't conflate it with the STR loophole.

Action plan

  • Place your STR in service after Jan 19, 2025 to qualify for 100% bonus (binding-contract rule applies).
  • Order the cost segregation study in year of placement.
  • Document material participation contemporaneously — calendar, hour logs, photos, communications.
  • Get your CPA aligned with your strategy BEFORE filing; this isn't a position to take alone.

OBBBA gave the STR loophole back its full original power. If you're a high earner and you own (or are about to own) a short-term rental, this is the year.
