Every year you own a rental property, depreciation quietly reduces your tax bill. It’s one of real estate’s best-known advantages — a deduction that costs you nothing out of pocket.

Then you sell, and the IRS wants some of it back.

Depreciation recapture is the tax on the sale that catches more investors off guard than almost anything else in the code — not because it’s hidden, but because it’s easy to forget about during the years when it isn’t due. Here’s exactly how it works, how it’s calculated, how it stacks with capital gains tax, and how investors legitimately plan around it.

General education, not tax advice. Recapture calculations are fact-specific. Confirm your numbers with a qualified CPA before any sale.

Why Recapture Exists

Depreciation is based on an assumption: that a building loses value over time and the IRS lets you deduct that loss year by year. For residential rental property, that’s 27.5 years, under IRC Section 168.

Real estate often doesn’t actually lose value — it appreciates. So when you sell, the IRS applies a mechanism to collect some of what it effectively lent you through those depreciation deductions. That mechanism is recapture.

The rule has teeth even if you never claimed the deduction. Under the “allowed or allowable” rule in IRC §1016(a)(2), your basis is reduced by the depreciation you were entitled to take — whether you actually claimed it or not. Skipping depreciation doesn’t avoid recapture. It just means you pay the tax without ever getting the benefit.

How Recapture Is Calculated

The core formula:

Adjusted Basis = Original Cost Basis − Accumulated Depreciation
Total Gain = Sale Price − Adjusted Basis

Recapture applies to the portion of that gain attributable to depreciation already taken, generally taxed under Section 1250 for real property at a maximum rate of 25% — separate from and in addition to ordinary capital gains tax on the remaining appreciation.

A simplified example: You bought a property for $300,000. Over 10 years you claimed $109,000 in depreciation, bringing your adjusted basis to $191,000. You sell for $400,000. Your total gain is $209,000. The $109,000 attributable to depreciation is taxed at up to 25% (roughly $27,250). The remaining $100,000 of appreciation is taxed at long-term capital gains rates.

This is why a property that “only” appreciated modestly can still generate a meaningful tax bill at sale — the depreciation portion is taxed at a higher rate than the appreciation itself.

The Three-Tax Stack at Sale

Selling a rental property can trigger up to three separate taxes stacking on top of each other:

Capital gains tax on appreciation — 0%, 15%, or 20% depending on income
Depreciation recapture under Section 1250 — up to 25%
Net Investment Income Tax (NIIT) — an additional 3.8% for higher-income taxpayers

Investors who model only capital gains tax before a sale are frequently surprised by how much larger the actual bill is once recapture and NIIT are layered in.

What Cost Segregation Does to Your Recapture Exposure

Cost segregation accelerating depreciation and increasing recapture exposure at sale

Cost segregation accelerates depreciation by reclassifying building components into shorter recovery periods, and with 100% bonus depreciation permanently restored under the One Big Beautiful Bill Act, those components can often be fully expensed in year one.

This is acceleration, not elimination. Every dollar of accelerated depreciation reduces your basis the same as standard depreciation would — it just does so faster. Which means an aggressive cost segregation study can meaningfully increase your recapture exposure at sale, even though the current-year tax savings were real and valuable.

This isn’t an argument against cost segregation — for most investors, the time value of an accelerated deduction today is worth considerably more than a larger tax bill years from now at sale. It’s an argument for knowing the number before you study, not discovering it at closing.

Three Ways Investors Plan Around It

1031 exchange. Rolling sale proceeds into a replacement property defers both capital gains and recapture — the liability doesn’t disappear, it transfers forward attached to the new property’s basis. Strict 45-day identification and 180-day closing windows apply, and the exchange must be structured before you receive any proceeds.
Timing the sale. Coordinating a disposition with a lower-income year, or spreading gain recognition via an installment sale, can reduce the marginal impact — worth modeling with your CPA well before a listing goes live.
Knowing the number before you decide. The single most common mistake is running the capital gains math and skipping recapture entirely. Calculate accumulated depreciation and the full three-tax stack before comparing a sale against a 1031 or a hold.

Why This Comes Down to Your Records

Every piece of this calculation depends on one thing: an accurate depreciation schedule, maintained from day one of ownership.

If you’ve missed depreciation in prior years, recapture still applies to the allowable amount — so skipping it only costs you the deduction, never the tax. If you’ve run a cost segregation study, your accumulated depreciation is higher and more complex to track across multiple asset classes. And if you’re holding property across multiple entities, each one needs its own accurate schedule.

Uncle Sam, RealBooks’ AI tax strategist, maintains depreciation schedules per property and per asset — including components identified through cost segregation — so your accumulated depreciation and projected recapture exposure are visible at any point, not reconstructed at closing.
Dollar Bill tracks cost basis from acquisition through every capital improvement, keeping the basis figure that recapture is calculated from accurate over the full hold period.
Penny keeps property-level income and expense records current, so the numbers feeding into your basis and depreciation schedule are never a year-end guess.

RealBooks organizes your records. It doesn’t calculate your final tax liability or provide tax advice — that’s your CPA’s role. What organized records change is whether you know your recapture exposure before you list the property, or find out at the closing table.

The Takeaway

Depreciation recapture isn’t a penalty — it’s the deferred cost of a deduction you already benefited from. The investors who handle it well aren’t avoiding it; they’re planning for it, by knowing their accumulated depreciation, modeling the full three-tax stack before a sale, and deciding deliberately between a 1031 exchange and a straight sale with the real numbers in front of them.

Your numbers should work as hard as your investments do.

Know your recapture exposure before you list — not at the closing table.
