Audit support includedFlat price for every study3 to 5 business days Selling a rental property after a cost segregation study triggers two different depreciation recapture calculations, not one. The real property portion of your depreciation falls under Section 1250 and is capped at a 25% federal rate as unrecaptured Section 1250 gain, while the personal property and land improvements that cost segregation pulled into 5, 7, and 15-year buckets fall under Section 1245 and get taxed as ordinary income, up to 37% for high W-2 earners in 2026. The recapture hits you whether or not you actually claimed the depreciation, because the IRS calculates it on depreciation "allowed or allowable," not just what you deducted.
- Cost segregation depreciation recapture rental property sale splits into two buckets: Section 1250 real property (capped at 25%) and Section 1245 personal property (ordinary income up to 37%).
- Recapture applies to depreciation you were entitled to take, even if you never claimed it on a return.
- A 1031 exchange defers both recapture buckets into the replacement property; an installment sale does not defer recapture past the year of sale.
- The more a study reclassifies into short-life assets, the larger the Section 1245 bucket taxed at ordinary rates when you sell.
Why This Matters
Cost segregation front-loads deductions in the early years of ownership by reclassifying parts of a building into shorter recovery periods. That's the whole appeal: a study that reclassifies 25% of a $500,000 property shifts roughly $125,000 into 5, 7, and 15-year buckets, generating deductions you'd otherwise wait 27.5 years to claim.
The tradeoff shows up at the exit. Every dollar of accelerated depreciation lowers your basis, and lower basis means more taxable gain when you sell. The question isn't whether recapture happens, it's which rate applies to which dollar, and that's where cost segregation actually helps you plan rather than hurts you.
Cost Segregation Depreciation Recapture Rental Property Sale: How the Split Works
When you sell, the IRS separates your depreciation recapture into two categories based on the asset class the depreciation came from.
| Recapture Type | Assets Covered | Max Federal Rate | Triggered By |
|---|---|---|---|
| Section 1250 | Building structure, roof, foundation (27.5-year residential real property) | 25% (unrecaptured Section 1250 gain) | Sale of any depreciated rental building |
| Section 1245 | Personal property and land improvements reclassified by cost segregation (5, 7, 15-year assets: appliances, carpet, fencing, driveways, landscaping) | Ordinary income rate, up to 37% | Sale after a cost segregation study accelerated depreciation into short-life assets |
The Section 1250 recapture rate never exceeds 25% for residential rental real property depreciated on the standard straight-line schedule, regardless of your tax bracket. The Section 1245 bucket has no cap. It's added to your other ordinary income and taxed at your marginal rate, which is why the split matters more for high earners than for anyone else.
Section 1250 Recapture: Capped at 25%
Unrecaptured Section 1250 gain applies to the portion of your gain attributable to straight-line depreciation on the building itself. Even if you're in the 37% bracket for wages, this slice of gain is capped at 25% federal tax. State taxes still apply on top and vary by where the property sits.
Section 1245 Recapture: Taxed Up to 37%
The personal property and land improvements a cost segregation study identifies get depreciated faster, which means more of the building's value sits in a bucket taxed at ordinary rates when you sell. On the same $500,000 property with 25% reclassified, roughly $125,000 in accumulated depreciation on short-life assets is recaptured as ordinary income rather than capped at 25%. For a taxpayer in the 37% bracket, that's a meaningfully higher rate on that slice of gain than the 1250 portion gets.
“Cost segregation doesn't create recapture, it just tells the IRS which rate applies to which dollar of gain.”
Why the Recapture Split Varies by Property
- Percentage reclassified by the study. A property with more site improvements, driveways, decks, appliances typically reclassifies a larger share into the Section 1245 bucket.
- Holding period. Longer ownership means more accumulated depreciation overall, in both buckets, by the time you sell.
- Bonus depreciation percentage claimed. Property acquired and placed in service after January 19, 2025 qualifies for 100% bonus depreciation under the One Big Beautiful Bill Act, front-loading more of the Section 1245 deduction into year one.
- Tax bracket at sale. The 1245 bucket rides your ordinary rate, so a high W-2 earner selling in a high-income year pays more on that slice than someone in a lower bracket.
- State income tax rate. Both recapture buckets face state tax on top of federal, and rates run from zero to double digits depending on the state.
- Use of a 1031 exchange. Rolling proceeds into a replacement property defers both recapture buckets rather than eliminating them.
Calculating Bonus Depreciation Recapture: A Worked Example
Assume a $500,000 residential rental where a study reclassified 25% of the depreciable basis, about $125,000, into 5, 7, and 15-year assets and claimed 100% bonus depreciation the year the property was placed in service. Over a holding period, that $125,000 was fully depreciated as an ordinary-income deduction.
At sale, that same $125,000 becomes Section 1245 recapture, taxed at your ordinary rate, up to 37% for a high-bracket seller. The remaining building depreciation, taken straight-line over 27.5 years, becomes Section 1250 gain capped at 25%. How to calculate bonus depreciation recapture walks through the mechanics year by year if you want to model your own numbers before listing a property.
The math only works this way because the deductions were real in the first place. A rental owner who skipped cost segregation entirely still owes Section 1250 recapture on straight-line depreciation, they just never captured the larger deductions that made the accelerated schedule worth it in years one through five.
Does a 1031 Exchange Avoid Depreciation Recapture?
A 1031 exchange defers both Section 1250 and Section 1245 recapture rather than eliminating them, rolling the deferred tax liability into the replacement property's basis. You still need to track the reclassified asset schedule from your original cost segregation study, because that basis carries forward and affects recapture on the eventual sale of the new property.
Do I Owe Recapture Tax If I Never Claimed the Depreciation?
Yes, recapture applies to depreciation "allowed or allowable" even if you never claimed it on a filed return. The IRS taxes you as if you took the deduction, so skipping it means you pay recapture without ever getting the benefit, which is the single most common argument for filing a Form 3115 catch-up before a sale rather than after.
Does Cost Segregation Increase My Tax Bill When I Sell?
Cost segregation doesn't increase your total tax bill, it changes the timing and the rate mix. You get larger deductions in early years at ordinary-income value, then pay some of that back at sale, split between the 25%-capped 1250 bucket and the ordinary-rate 1245 bucket, a trade most high-bracket owners still come out ahead on.
A study that documents each asset's class at the time of purchase, appliances, flooring, fencing, decking, gives your CPA the paper trail needed to calculate the 1245/1250 split correctly at sale instead of guessing. That documentation matters more at the exit than it does going in, because an inaccurate split either overpays the IRS or invites a recapture recalculation during an audit.

FAQ
What is the difference between Section 1250 and Section 1245 recapture?
Section 1250 recapture applies to real property (the building) and is capped at 25% federal tax; Section 1245 recapture applies to personal property and land improvements reclassified by cost segregation and is taxed as ordinary income, up to 37% in 2026.
Can I avoid depreciation recapture by not doing a cost segregation study?
No, skipping cost segregation doesn't avoid recapture, you still owe Section 1250 recapture on straight-line building depreciation, you just miss the larger deductions cost segregation would have generated in the earlier years.
How much of my gain is taxed at 37% versus 25% after cost segregation?
It depends on the percentage of the property a study reclassified into short-life assets; a property with 25% reclassified typically shifts a proportional share of accumulated depreciation into the 37%-capped ordinary-income bucket at sale.
Does a 1031 exchange eliminate cost segregation recapture?
No, a 1031 exchange defers both Section 1250 and Section 1245 recapture into the replacement property's basis rather than eliminating the tax liability.
Do I pay recapture tax on depreciation I never actually claimed?
Yes, the IRS calculates recapture on depreciation allowed or allowable, meaning you owe the tax even if you never filed the deduction, which is why a Form 3115 catch-up before selling matters.
Is depreciation recapture taxed at capital gains rates or ordinary rates?
It's split: unrecaptured Section 1250 gain is capped at 25%, while Section 1245 gain on personal property is taxed at your ordinary income rate, up to 37% for high earners in 2026.
Does an installment sale defer depreciation recapture?
No, depreciation recapture is generally recognized in full in the year of sale even on an installment sale, only the capital gain portion beyond recapture can be spread over future payments.
Should I do a cost segregation study if I plan to sell within a few years?
A shorter holding period reduces the time you benefit from accelerated deductions before facing recapture, so the math depends on your bracket, the reclassified percentage, and whether a 1031 exchange is on the table at sale.
One Last Thing
The recapture math rewards owners who plan the sale before it happens, not after. Pulling the original cost segregation report and asset schedule before listing a property, rather than scrambling for it during closing, is what lets a CPA calculate the 1245/1250 split accurately instead of defaulting to a conservative, higher-tax estimate.
