Every year you own rental property, you deduct depreciation against your rental income. When you sell, the IRS takes back a portion of those deductions in the form of depreciation recapture tax -- a federal tax of up to 25% on the depreciation you claimed (or were allowed to claim, even if you didn't). For a property held 15 years, the recapture bill alone can exceed $50,000 before capital gains tax enters the picture.
The IRS calculates recapture based on depreciation you were allowed to claim, not what you actually claimed. If your tax preparer missed the deduction for several years, you still owe recapture on the full amount. Failing to claim depreciation costs you twice -- you miss the annual deduction and still pay the recapture tax when you sell.
Depreciation recapture is the IRS clawing back tax benefits you received while you owned the property. When you buy rental property, you depreciate the building (not the land) over its useful life. Technical detail
The lower your basis, the larger your gain on sale. Depreciation recapture is the portion of that gain attributable to the depreciation deductions you took, taxed at a special rate that is separate from and higher than the standard long-term capital gains rate.
The 25% Rate
Depreciation recapture on real property is taxed at a maximum federal rate of 25%. IRC Section 1(h)(1)(E) caps the tax rate on "unrecaptured Section 1250 gain" at 25%. This applies to most rental property sold today, because virtually all residential real property placed in service after 1986 uses straight-line depreciation.
The technical name is "unrecaptured Section 1250 gain." Technical detail
The 25% is a ceiling, not a floor. If your marginal rate is below 25%, you pay the lower rate.
A Concrete Example
The property: Purchased for $400,000 ($80,000 land, $320,000 building). Held 15 years. Sold for $550,000.
Depreciation claimed: $320,000 / 27.5 years = $11,636/year. Over 15 years: $174,545.
Gain calculation: Adjusted basis is $400,000 - $174,545 = $225,455. Total gain is $324,545.
That gain breaks into two taxable pieces:
- Depreciation recapture: $174,545 at 25% = $43,636
- Capital gain above original cost: $150,000 at 15% or 20% = $22,500 to $30,000
The recapture is the larger tax hit. On top of both, the 3.8% Net Investment Income Tax (NIIT) may apply to the entire gain for taxpayers with modified adjusted gross income above $200,000 (single) or $250,000 (married). IRC Section 1411 imposes the 3.8% NIIT on net investment income, including gain from selling rental property. That adds roughly $12,000 in this example, bringing the combined federal tax to $78,000-$86,000 -- before state taxes.
The Tax Stacking Order
The IRS layers these taxes in a specific order:
- Layer 1: The first dollars of gain (up to total depreciation claimed) are taxed at the 25% unrecaptured Section 1250 rate
- Layer 2: Remaining gain above original cost is taxed at the long-term capital gains rate (0%, 15%, or 20%) IRC Section 1(h)(1)(C) and (D)
- Layer 3: The 3.8% NIIT applies to the entire gain for taxpayers above the MAGI thresholds
A high-income investor faces a combined federal rate of 28.8% on the recapture portion (25% + 3.8%) and 23.8% on the capital gain portion (20% + 3.8%).
- Depreciation recapture: $174,545 at 25% = $43,636
- Capital gain above original cost: $150,000 at 20% = $30,000
- Net Investment Income Tax (3.8%) on entire $324,545 gain = $12,333
- Total before state taxes
- Replace with equal or greater value property
- Reinvest all net equity and replace all debt
- Identify replacement within 45 days, close within 180 days
- Both recapture and capital gain deferred entirely
The IRS calculates recapture based on the depreciation you were allowed to claim, not what you actually claimed (IRS Publication 544). If your tax preparer missed the deduction for five years, you still owe recapture on the full amount you should have deducted. Failing to claim depreciation costs you twice: you miss the annual deduction, and you still pay the recapture tax on sale.
If you discover missed depreciation, file Form 3115 (Application for Change in Accounting Method) to catch up before you sell. Revenue Procedure 2015-13 allows automatic accounting method changes for depreciation corrections through Form 3115.
If you have missed depreciation deductions in prior years, file Form 3115 to catch up before you sell the property. This is an automatic accounting method change -- you do not need IRS approval. It lets you claim all the missed deductions in a single year, and it prevents you from paying recapture on deductions you never actually received.
A 1031 like-kind exchange is the primary tool for deferring depreciation recapture. When you reinvest the full proceeds into another qualifying property through a qualified intermediary, both the capital gain and the depreciation recapture are deferred. Technical detail
Full deferral requires:
- Replacement property of equal or greater value
- All net equity reinvested
- All debt replaced (through new financing or additional cash)
- Identification within 45 days, closing within 180 days
If you receive cash or reduce your debt ("boot"), the IRS applies gain recognition to the depreciation recapture portion first. Even a small amount of boot triggers recapture at the 25% rate.
The "Swap Till You Drop" Strategy
Many investors use successive 1031 exchanges to defer recapture indefinitely. The endgame is the step-up in basis at death: when the property owner dies, the heir's basis resets to fair market value under IRC Section 1014, and the deferred depreciation recapture is permanently eliminated.
This is the most powerful combination in real estate tax planning. Depreciation provides annual tax savings, exchanges defer the recapture, and the step-up erases the accumulated liability at death.
Depreciation recapture is reported on Form 4797 (Sales of Business Property). Your CPA separates the gain into its components -- recapture on Part III of Form 4797, remaining capital gain on Form 8949 and Schedule D, and the NIIT calculation on Form 8960. The allocation between recapture and capital gain, the interaction with passive activity rules under Section 469, and state tax implications make this a filing that warrants professional help.
