Bonus Depreciation for Short-Term Rentals in 2026

Bonus depreciation lets a taxpayer deduct a percentage of the cost of qualifying shorter-life property in the year it is placed in service, rather than spreading it across the asset's recovery period. For a short-term rental, the qualifying property is what a cost segregation study reclassifies out of the building: carpet, appliances, decorative lighting, specialty electrical, furnishings, and land improvements such as driveways, landscaping and pools. This is where it stood in 2026, which was the year the tax strategy is back at full strength and market selection decides everything.

What 2026 changed

2026 is the first full year with 100% bonus depreciation permanently restored under OBBBA. For a high earner buying a property that clears the seven-day average stay test and where they materially participate, the first-year deduction is back to where it was in 2021. What is not back to 2021 is the market: supply is deeper, regulation is tighter in the places that tightened, and buying badly is no longer covered by a rising tide.

The spread between markets is wider than at any point in this period. Arizona and Tennessee are workable and stable. California and much of Colorado are not, for reasons that have nothing to do with demand.

100% bonus depreciation applies under OBBBA to qualifying property acquired and placed in service after 19 January 2025, and it is permanent rather than scheduled to phase down.

How it works

Bonus depreciation lets a taxpayer deduct a percentage of the cost of qualifying shorter-life property in the year it is placed in service, rather than spreading it across the asset's recovery period. For a short-term rental, the qualifying property is what a cost segregation study reclassifies out of the building: carpet, appliances, decorative lighting, specialty electrical, furnishings, and land improvements such as driveways, landscaping and pools.

1. A cost segregation study separates the purchase into components and assigns each to its correct recovery period, commonly 5, 7 and 15 years for the pieces that come out of the building shell.
2. Bonus depreciation then applies to those shorter-life components at whatever percentage the law allows for the year the property is placed in service.
3. The remaining structure continues over its long recovery period, 39 years for a short-term rental with an average stay of seven days or less, or 27.5 for residential rental property.
4. None of this is usable against wage income unless the activity clears the seven-day average period of customer use and the owner materially participates.

What that meant in 2026 specifically

With 100% bonus depreciation permanent, the constraint has shifted back to the participation tests and the seven-day average, which are operational rather than legislative and therefore inside the owner's control.

The risk in 2026 is the same one that has been true throughout: buying on the tax benefit rather than on the property. A permanent 100% deduction makes a good purchase excellent and does not make a bad purchase acceptable.

2026 rewards market selection and basis. The tax side is as favourable as it has ever been, which means the differentiator is everything else.

Where it goes wrong

The failure modes are consistent across years, which is itself useful information: they are not caused by the market cycle, so a different year does not protect you from them.

• Treating the deduction as free money. It is a timing shift, and on sale the depreciation taken is recaptured, with Section 1245 recapture on personal property components taxed as ordinary income.
• Commissioning a study before confirming the participation position, which produces a large loss that is passive and generally suspended.
• Assuming the placed-in-service date is the closing date. It is when the property is ready and available for its intended use, which for a rental generally means available for booking.

What a buyer should have done in 2026

2026 rewards market selection and basis. The tax side is as favourable as it has ever been, which means the differentiator is everything else.

The underwriting discipline does not change with the year. Twelve individual monthly revenue figures from a comparable set you assembled, a complete expense stack including reserves, and a stress test at 75% of projection that still covers debt service.

We screen roughly a thousand deals a week and eliminate about 98% of them. That ratio has held across every year on this site, through the boom, the correction and the stabilisation, because it is a function of how listings are selected rather than of the market.

What generalises, and what does not

Reading a year in isolation is the most common analytical error in this business. 2026 had its own conditions, and someone who learned the wrong lesson from it carried that lesson into a market that no longer rewarded it.

What generalises is the mechanics above. The definitions, the tests, the sequence and the failure modes are the same in every year on this site, which is why they are worth learning properly once rather than relearning each cycle.

What does not generalise is the environment: the cost of capital, the depth of supply, the bonus depreciation percentage, and the regulatory posture of a given jurisdiction. Those change, sometimes abruptly, and a model that treats them as fixed is a model that was only ever right about one year.

The practical consequence is to build the analysis so the environment is an input rather than an assumption. A property that only works at one interest rate, one occupancy level and one tax treatment is not an investment thesis, it is a bet that nothing moves.
