Depreciation Recapture on Rental Property Sale: The Hidden 25% Tax Inside a $400,000 Gain

The setup: a $340,000 duplex, 12 years of depreciation, and a $400,000 gain

A Dallas couple (married filing jointly, combined W-2 income of $280,000) bought a rental duplex in 2014 for $400,000 total. Land value: $60,000. Depreciable basis: $340,000. They’ve been depreciating the building on the 27.5-year residential MACRS schedule ever since.

In 2026, they sell for $600,000. Their mortgage payoff, closing costs, and selling expenses net out to a $400,000 realized gain. They expect a single long-term capital gains rate to apply — 15% or maybe 20% — and budget $60,000–$80,000 for the federal tax bill.

The actual bill is closer to $97,000. The gap is depreciation recapture — and it catches landlords who’ve never modeled the §1250 split.

How the IRS calculates accumulated depreciation on a residential rental

Under the Modified Accelerated Cost Recovery System (MACRS), residential rental property is depreciated straight-line over 27.5 years. The math is mechanical:

• Depreciable basis: $340,000 (purchase price minus land)
• Annual depreciation: $340,000 ÷ 27.5 = $12,364/year
• 12 years of ownership: $12,364 × 12 = $148,364 total depreciation
• Adjusted basis at sale: $340,000 − $148,364 = $191,636

That $148,364 reduced their taxable rental income every year — saving them roughly $35,607 in federal taxes over 12 years at the 24% bracket. But the IRS doesn’t forget. When the property sells, every dollar of depreciation taken (or allowable) gets recaptured.

The part most landlords miss: under IRC §1016(a)(2), recapture applies to depreciation “allowed or allowable.” If you owned a rental for 12 years and never filed depreciation deductions — because your CPA forgot, because you didn’t know, because you chose not to — the IRS still calculates recapture on the full $148,364 you were entitled to deduct. You lost the annual benefit but you owe the exit tax anyway. This is one of the most expensive mistakes in rental property ownership.

Unrecaptured Section 1250 gain: why 25% applies even in the 15% LTCG bracket

The $400,000 gain on this sale is not a single number. The IRS splits it into two pieces with different tax treatments:

The recapture piece — $148,364 — is taxed under IRC §1(h)(1)(E) at a maximum rate of 25%. This is separate from and higher than the 15% or 20% LTCG rate. The 25% is a ceiling: if your ordinary income rate is below 25% (say you’re in the 12% bracket), you’d pay only 12% on the recapture. But most rental sellers with six-figure gains land well above that threshold once the gain stacks onto their other income.

Why it’s called “unrecaptured” Section 1250 gain: the full depreciation recapture on real property could be taxed at ordinary income rates (like §1245 recapture on equipment). Congress carved out the 25% ceiling for buildings as a compromise — hence “unrecaptured” meaning the portion that escapes full ordinary income treatment. It’s favorable compared to §1245, but it’s still materially higher than the 15%–20% LTCG rate most sellers expect.

The worked example: $400,000 gain, two tax rates, one surprise

Here’s the full federal tax calculation for the Dallas couple (MFJ, $280,000 W-2 income, selling in 2026):

Why 20% LTCG instead of 15%: this couple’s $280,000 W-2 income plus the $251,636 of LTCG pushes their taxable income well above the $600,050 MFJ threshold where the 20% LTCG rate kicks in (2026). At lower income levels — say a retired couple with $60,000 of pension income — the LTCG portion would be taxed at 15%, and the NIIT might not apply at all if MAGI stays below $250,000.

Why NIIT on the appreciation but not the recapture: the 3.8% Net Investment Income Tax under IRC §1411 applies to net investment income, which includes capital gains. The depreciation recapture portion is technically also subject to NIIT for taxpayers above the MAGI threshold — so the actual NIIT bill could be even higher. In our simplified example, applying NIIT only to the appreciation understates the true cost. For precision, run the full Form 8960 with all investment income included.

What the couple expected vs. what they owe

That $37,000 gap is roughly the price of a new roof, a year of property management fees, or — if they’d planned for it — the closing costs on a 1031 replacement property.

Section 1245 vs. Section 1250: the rental property distinction

Not all rental property depreciation is recaptured at 25%. The building and structural components fall under §1250 (25% max). But appliances, carpeting, window treatments, and HVAC units are §1245 property — and their depreciation recapture is taxed as ordinary income at your marginal rate, up to 37% in 2026.

For most residential landlords, §1245 property is a small fraction of the total depreciation. If the couple separately depreciated $15,000 of appliances and fixtures over 5–7 years, that recapture is taxed at their 24% marginal rate (potentially 32% once the sale income pushes them up a bracket). The building’s $133,364 of recapture stays at 25%.

This distinction matters most for landlords who did a cost segregation study — accelerating depreciation by reclassifying components as 5-, 7-, or 15-year property instead of 27.5-year. Cost segregation front-loads the tax benefit during ownership, but the accelerated depreciation on those reclassified components is recaptured at ordinary income rates (§1245), not the more favorable 25%.

Strategy 1: 1031 like-kind exchange — defer everything, carry the basis forward

Under IRC §1031, selling one rental property and acquiring a like-kind replacement property within the required timelines defers both the LTCG and the depreciation recapture. The couple pays $0 in tax on the $400,000 gain — today.

But here’s what defers, not disappears: the replacement property inherits the relinquished property’s adjusted basis. If they buy a $700,000 replacement, their depreciable basis isn’t $700,000 — it’s the old adjusted basis ($191,636) plus any additional cash invested. The $148,364 of deferred recapture is embedded in the new property’s lower basis, waiting to surface on the next sale.

Mechanics that must be perfect for the deferral to work:

• 45-day identification window: identify up to three replacement properties within 45 calendar days of closing on the relinquished property
• 180-day closing window: close on the replacement within 180 days (or your tax filing deadline, whichever comes first)
• Qualified Intermediary (QI): a third party must hold the sale proceeds — you cannot touch the money. The QI requirement is strict under Rev. Proc. 2000-37
• Like-kind: since TCJA (2017), only real property qualifies for 1031. No personal property, no crypto, no equipment

I think for most rental investors over 60 who want to simplify their portfolio, paying the recapture and LTCG now can be the better move. The net after-tax math depends on whether you intend to hold the replacement until death (step-up eliminates everything) or sell it in 5–10 years (at which point the compounding deferred recapture is even larger).

The death escape: IRC §1014 step-up wipes recapture

If the couple holds any rental property — original or 1031 replacement — until death, their heirs receive a basis stepped up to the date-of-death fair market value under IRC §1014. This eliminates the accumulated depreciation recapture entirely. No 25% recapture tax. No LTCG. The heirs’ basis starts at FMV.

This is why the “buy, depreciate, 1031, hold to death” strategy is one of the most powerful wealth-transfer plays in real estate. It’s also why the step-up in basis is one of the largest tax expenditures in the Internal Revenue Code.

Strategy 2: installment sale — spread the gain, manage the brackets

An installment sale under IRC §453 lets the seller receive the purchase price over multiple years, reporting gain proportionally as payments arrive.

The critical limitation for rental property: under §453(i), depreciation recapture on §1250 property is recognized in the year of sale regardless of installment terms. The $148,364 of recapture hits in year one — you cannot defer it across the installment schedule. However, the $251,636 of true appreciation (LTCG) can be spread over the payment period.

What this looks like on a 5-year installment:

The benefit: spreading $251,636 of LTCG across 5 years can keep each year’s total income below IRMAA thresholds ($206K single / $258K MFJ for the first Part B surcharge tier in 2026) and potentially below the NIIT MAGI threshold ($200K single / $250K MFJ). On a $251,636 gain, avoiding the 3.8% NIIT saves $9,562 — which can offset the interest rate discount you give the buyer on the installment note.

Where the installment sale falls short: because recapture is front-loaded into year one, the biggest tax hit happens immediately anyway. The installment sale is most valuable when the LTCG portion is large relative to the recapture — properties that appreciated significantly beyond the depreciation amount.

The scenario most landlords don’t model: cost segregation acceleration

Landlords who ran a cost segregation study during ownership — reclassifying portions of the building as 5-year, 7-year, or 15-year MACRS property to accelerate depreciation deductions — face a sharper version of this problem at sale.

Cost segregation is excellent during ownership: it front-loads depreciation into early years, improving cash flow and reducing taxable rental income when you need it most. But at sale, the components reclassified as §1245 property (personal property) are recaptured at ordinary income rates — not the 25% ceiling. At the 32% or 35% bracket, that’s 7–10 percentage points more on every dollar of accelerated depreciation.

The math still usually favors cost segregation — the time value of earlier deductions outweighs the higher recapture rate at sale, especially over a 10+ year hold. But it means the exit tax bill is more complex and potentially higher than the standard 25% recapture model.

When recapture disappears entirely: inheritance and the step-up

Under IRC §1014(a), when a property owner dies, the heir’s basis in inherited property steps up (or down) to the date-of-death fair market value. This wipes out:

• All accumulated depreciation and the associated 25% recapture
• All unrealized capital gains
• All deferred gains from prior 1031 exchanges embedded in the basis

For the Dallas couple’s duplex: if one spouse dies while the property is still owned, the surviving spouse (in a non-community-property state like Texas, which is actually a community property state) gets a full step-up on the community property share. In Texas, because it’s a community property state, both halves of the property receive a full step-up at the first spouse’s death — the entire $400,000 of embedded gain and $148,364 of recapture vanish.

In non-community-property states, only the deceased spouse’s half gets the step-up. The surviving spouse’s half retains the old adjusted basis and the associated recapture exposure. The community property states (CA, AZ, ID, LA, NV, NM, TX, WA, WI) have a material advantage here.

The decision framework: sell, exchange, or hold to death?

The numbers that matter

A rental property sale is not one tax event — it’s two. The depreciation recapture at 25% and the capital gain at 15%–23.8% are calculated separately, reported on different schedules, and respond to different planning strategies.

For the Dallas couple: their $400,000 gain produces a $96,980 federal tax bill — 61% higher than the $60,000 they budgeted. The $37,000 surprise is the depreciation recapture they took for granted during 12 years of ownership. Every $12,364 annual deduction that reduced their rental income was a loan from the IRS, not a gift. At sale, the IRS collects.

Model the recapture before listing. If a 1031 exchange makes sense, line up your Qualified Intermediary and identify replacement targets before closing — you have exactly 45 days from the sale date to identify, and that window closes faster than most sellers expect. If you’re selling outright, the recapture is the cost of a decade of tax-sheltered rental income. Price it in.
