Every investor who accelerates depreciation eventually asks one question: what happens when I sell?
The answer is depreciation recapture. It applies whenever you sell a rental property at a gain, with or without a cost segregation study. Recapture is not a reason to avoid acceleration. For most investors who hold for several years and exit through a sale, a 1031 exchange, or a step-up at death, the upfront savings outweigh the recapture cost.
This article explains how recapture works, the real tax rates, a full net-benefit example with the math shown, and the strategies that reduce or defer recapture.
Key Takeaways
- Depreciation recapture applies only when you sell at a gain, and it applies whether or not you did a cost segregation study.
- Straight-line building depreciation is taxed as unrecaptured Section 1250 gain at a maximum 25% rate, and high-income investors may also owe the 3.8% net investment income tax.
- Reclassified components are recaptured as ordinary income at your marginal rate, up to 37%.
- Cost segregation does not increase your total lifetime depreciation. It changes the timing and the recapture rate on part of it.
- On a nominal basis, the extra deductions and the extra tax at sale roughly cancel. The advantage comes from time value: you reinvest front-loaded savings for years before recapture is due.
- A 1031 exchange defers recapture, and a step-up in basis at death eliminates it. An installment sale spreads capital gain, but Section 1245 recapture and any Section 1250 recapture above straight line are taxed in full in the year of sale; unrecaptured Section 1250 gain can still be reported on the installment method, front-loaded into the earliest payments.
What Is Depreciation Recapture?
When you sell a rental property for more than its adjusted basis, the IRS taxes the part of your gain that comes from depreciation. This reverses a deduction you already used. It is not an extra penalty.
Recapture applies to all depreciation, standard and accelerated. A study does not create recapture. Depreciation does. A study changes the timing of your deductions and the classification of your assets.
Two rules govern real estate recapture (IRS Publication 544):
Building depreciation, the 27.5-year residential or 39-year commercial structure, is taxed as unrecaptured Section 1250 gain. The rate is the lesser of your ordinary rate or 25% (IRS Topic 409). High-income investors may also owe the 3.8% net investment income tax (IRS).
Reclassified components, the 5-, 7-, and 15-year assets a study identifies, are recaptured as ordinary income at your marginal rate, up to 37%. Personal property falls under Section 1245. Land improvements are Section 1250 property, but their depreciation above the straight-line amount is also recaptured as ordinary income.
Does cost segregation create more recapture than standard depreciation?
No. Over the property's full depreciable life, you claim the same total depreciation either way. A study front-loads deductions into the early years. It does not increase the total. At sale, you recapture the depreciation you claimed. The difference is the rate on part of it and the timing of the benefit.
The Real Tax Rates: Recapture vs. Capital Gains
The rate you recapture at is not always the rate you deducted at. That spread drives the result.
Building depreciation is deducted at up to 37% and recaptured at a maximum 25%. That gap is a permanent saving on the building portion.
Reclassified components tell the opposite story. You deduct them at up to 37% and recapture them at up to 37%. There is no rate saving there, only timing. Acceleration also shifts part of your depreciation out of the 25% bucket and into the 37% bucket. Across a typical hold, these rate effects roughly offset. The decisive advantage is the time value of taking deductions now, covered below.
Net Benefit Analysis: A Full Example
Here is a complete scenario. The assumptions are stated so you can follow the math.
- Property: $1.2 million commercial building
- Land value: 15% ($180,000)
- Depreciable basis: $1,020,000
- Hold period: 10 years
- Sale price: $1.5 million
- Marginal tax rate: 37%
- Net investment income tax: 3.8% applies to all sale-gain layers in this simplified example
- Bonus depreciation: 100%, which is permanent for qualified property acquired after January 19, 2025 under the One Big Beautiful Bill Act (IRS guidance)
With Cost Segregation
The study reclassifies 30% of the depreciable basis, $306,000, into 5- and 15-year property.
Year 1:
- Bonus depreciation on reclassified components: $306,000
- Straight-line depreciation on the remaining $714,000 ($714,000 ÷ 39): ~$18,300
- Total year 1 deduction: ~$324,300
- Year 1 tax saving at 37%: ~$120,000
Over 10 years:
- Reclassified components: $306,000 (deducted in year 1)
- Building depreciation: $714,000 ÷ 39 × 10 = ~$183,000
- Total depreciation claimed: ~$489,000
At sale ($1.5M):
- Adjusted basis: $1,200,000 − $489,000 = $711,000
- Total gain: $1,500,000 − $711,000 = $789,000
- Ordinary-income recapture (reclassified components): $306,000 × 37% = $113,220, plus $11,628 NIIT = $124,848
- Unrecaptured Section 1250 gain (building): $183,000 × 25% = $45,750, plus $6,954 NIIT = $52,704
- Capital gain (appreciation): $300,000 × 23.8% = $71,400
- Total tax at sale: ~$248,952
This example conservatively treats all reclassified basis as ordinary-income recapture. In practice, the 15-year land-improvement slice is Section 1250 property: after a 10-year hold, the straight-line-equivalent portion is generally unrecaptured Section 1250 gain capped at 25%, while only depreciation above straight line is ordinary-income recapture. That means the real after-sale result may be somewhat better than the simplified math shown here.
Without Cost Segregation
All $1,020,000 depreciates over 39 years (standard depreciation).
- Year 1 deduction: $1,020,000 ÷ 39 = ~$26,150. Tax saving at 37%: ~$9,700.
- Over 10 years: ~$261,500 claimed.
At sale ($1.5M):
- Adjusted basis: $1,200,000 − $261,500 = $938,500
- Total gain: $1,500,000 − $938,500 = $561,500
- Unrecaptured Section 1250 gain: $261,500 × 25% = $65,375
- Capital gain: $300,000 × 23.8% = $71,400
- Total tax at sale: ~$146,712
The Net Comparison
Read the numbers carefully. Cost segregation produces about $227,500 more in deductions over the hold, worth roughly $84,000 in tax savings at 37%. It also costs about $102,240 more at sale under the simplified NIIT-inclusive math above. On a nominal basis, those two figures remain close, and the conservative treatment of the 15-year assets means the real result may be somewhat better.
So the case for acceleration is not a large nominal windfall. It is timing. That is where the real value sits.
Time Value of Money: Where the Benefit Comes From
Cost segregation front-loads the savings. In this example, you receive about $110,000 more in year one than you would without a study. You do not pay the extra ~$102,240 until you sell in year 10.
Money in hand today is worth more than the same amount a decade later. Reinvest the front-loaded savings at a conservative 8% annual return, and the present-value advantage over the 10-year hold remains meaningful, even after paying every dollar of recapture.
The longer you hold, the more that timing advantage compounds. The math favors taking the deduction now, as long as you hold long enough for the deferral to work.
What if I sell sooner than expected?
The benefit shrinks but usually stays positive. Bonus depreciation is a full first-year deduction regardless of hold period, so your upfront savings do not change. You simply have fewer years for those savings to compound before recapture is due. A sale at a loss is different: with no gain, recapture generally does not apply.
Strategies That Reduce or Defer Recapture
Recapture is not always paid at full rates in the year you exit. Several strategies change the outcome.
1031 Exchange
A 1031 exchange defers both capital gain and depreciation recapture when you exchange into qualifying like-kind real property (IRS). Since the Tax Cuts and Jobs Act, Section 1031 applies only to real property, but the exchange definition is separate from the depreciation classification: many items treated as Section 1245 property for depreciation can still qualify as real property for exchange purposes if they are inherently permanent structures or structural components (Reg. §1.1031(a)-3). Genuine personal property, such as appliances, furniture, or removable equipment, does not qualify, except to the extent it is incidental property under Reg. §1.1031(k)-1(g)(7), generally capped at 15% of the replacement property's value. The deferred amount carries into the new property's basis. Investors who exchange repeatedly can defer recapture across an entire holding career. Any cash, debt relief, or nonqualifying property you take out is taxed first, and recapture comes out of that amount before capital gain.
Step-Up in Basis at Death
If you hold the property until death, your heirs take a basis equal to fair market value on the date of death (IRC §1014). Because there is no sale, the depreciation recapture is eliminated. Heirs can then run a new cost segregation study on the stepped-up basis and begin depreciating again.
Installment Sale
An installment sale spreads the capital-gain portion over several years, but it does not defer ordinary-income recapture. Section 1245 recapture and any Section 1250 recapture above straight line are taxed in full in the year of sale (Section 453(i)), even if you receive payments later (IRS Topic 705). Unrecaptured Section 1250 gain can still be reported on the installment method, but it is taken into account before your capital gain, so it lands in the earliest payments (Reg. §1.453-12). Because a study increases the ordinary-income recapture layer, an installment sale is often a weak exit for a heavily depreciated property.
Holding Longer
The longer you hold, the more standard depreciation you would have claimed anyway. Over a full 27.5- or 39-year life, total depreciation is the same with or without a study. The extra recapture from acceleration shrinks relative to the total, and the timing advantage grows.
Can I avoid recapture by converting the property to personal use?
No. The IRS requires recapture on depreciation claimed during the rental period, whatever the property's use at sale. Converting a rental to your primary residence does not erase it. You may still exclude up to $250,000 of gain ($500,000 for joint filers) under the Section 121 exclusion, but that exclusion never covers depreciation recapture (IRS). The Section 121 nonqualified-use rule can also prorate the exclusion for post-2008 rental years before the property became your residence, so a 10-year rental followed by 2 years of personal residence does not generally get the full exclusion on the entire gain.
The Bottom Line
Recapture is real, and it is predictable. For investors who hold for several years and plan their exit, the numbers favor accelerating depreciation and managing recapture later. The benefit is mostly about timing, and it grows the longer you hold. Acceleration is weakest for short holds, low-basis properties, high state tax rates, or installment sales, so model your own situation before you decide.
