What depreciation recapture is, and how a sold rental gets taxed

Depreciation recapture is one of the least-understood taxes in residential real estate, and it surprises sellers most often when a home that was once a rental gets sold. The short version: while a property is rented, its owner deducts depreciation each year, a paper expense that reduces taxable rental income. When the property sells, the IRS recaptures that depreciation, taxing it at a rate up to 25%.3 It is separate from ordinary capital gains tax, and the primary-residence exclusion does not shield it.

The recapture is not a penalty and not a surprise the IRS sprang on anyone. It is the back end of a deal the tax code offered up front: the depreciation deduction lowered taxable income during the rental years, and recapture collects tax on that benefit when the property is sold. The problem is timing. The deduction arrives in small annual pieces; the recapture arrives all at once, years later, often when the seller has forgotten the deduction ever happened.

How depreciation works while you own the property

When a property generates rental income, the owner is allowed to deduct depreciation, the gradual using-up of the building, as an expense against that income. Residential rental property is depreciated on a straight-line basis over 27.5 years.1 An owner with a building basis of $220,000 deducts roughly $8,000 each year ($220,000 divided by 27.5).

Two details matter. First, only the building depreciates, not the land. At the time a property is placed in service as a rental, its cost is allocated between land and improvements, and only the improvements portion is depreciable. Second, depreciation is generally not optional in practice. The deduction is available every year the property is held as a rental, and the tax consequences of skipping it are worse than the consequences of taking it, for reasons the allowed-or-allowable section below explains.

Each year of depreciation reduces the property's adjusted basis, the figure the eventual gain is measured against. This is the mechanical link between the deduction and the recapture: every dollar of depreciation deducted is a dollar the basis drops, and a lower basis means a larger gain at sale.

What recapture means when you sell

When the property sells, the gain is the sale price minus selling costs minus the adjusted basis. Because depreciation lowered the basis, the gain is larger than it would have been on an identical property that was never rented.

The IRS then splits that gain into two parts:

The label "Section 1250" refers to the part of the tax code covering real property. A separate provision, Section 1245, covers personal property such as appliances or equipment that were depreciated on their own schedules; those recapture as ordinary income rather than at the 25% cap. For a typical house sale, the building is Section 1250 property and the 25% cap applies.

The allowed-or-allowable rule

Here is the rule that catches owners who tried to keep things simple. The tax code reduces a property's basis by depreciation allowed or allowable, whichever is greater.1 "Allowable" means the depreciation the owner could have claimed, whether or not they actually did.

The practical consequence: an owner who rented a property for several years but never claimed the depreciation deduction does not escape recapture. The IRS still treats the basis as reduced by the depreciation that was available, and still taxes that amount as unrecaptured Section 1250 gain at sale. The owner gets the worst of both outcomes, no deduction during the rental years, and full recapture at sale.

Missed depreciation can sometimes be corrected. The mechanism is Form 3115, an application to change accounting method, which can allow an owner to claim the catch-up depreciation that should have been taken. This is firmly tax-professional territory; the form and the calculations behind it are not a do-it-yourself exercise.

Depreciation recapture and the Section 121 exclusion

The most common and most costly misunderstanding is the assumption that the Section 121 primary-residence exclusion makes the whole thing disappear.

Section 121 lets a qualifying seller exclude up to $250,000 of gain ($500,000 for married joint filers) on the sale of a primary residence.2 It is a powerful exclusion. But it has a specific carve-out: it does not apply to depreciation claimed on the property after May 6, 1997.2 That depreciation is recaptured regardless of how much of the rest of the gain Section 121 covers.

In other words, Section 121 and depreciation recapture do not overlap. Section 121 shields the appreciation. Recapture taxes the depreciation. A seller can qualify fully for the exclusion, owe nothing on six figures of appreciation, and still owe recapture tax on the depreciation taken during the years the home was a rental.

Converted homes, the most common surprise

The classic sequence runs like this. A homeowner buys a house, lives in it, then moves, perhaps for a job, and rents the house out for a few years before selling. They know about the Section 121 exclusion, they know their gain is under the limit, and they expect to owe no tax. The recapture is the part they did not see coming.

Consider concrete numbers. A buyer purchases a house for $300,000 and lives in it for six years. They then relocate and rent the house out for three years before selling it for $480,000. Of the original cost, $220,000 was allocated to the building, producing depreciation of roughly $8,000 per year, or $24,000 over the three rental years. At sale, the adjusted basis is $300,000 minus $24,000, or $276,000. Ignoring selling costs for simplicity, the total gain is $480,000 minus $276,000, or $204,000.

That $204,000 splits into $24,000 of recapture (equal to the depreciation taken) and $180,000 of appreciation. Because the owner used the home as a primary residence for two of the five years before the sale, they meet the Section 121 ownership-and-use test, and the $180,000 of appreciation is fully excluded. But the $24,000 of recapture is not. It is taxed at up to 25%, producing a federal tax bill of up to $6,000 on a sale the seller expected to be entirely tax-free.

The number is rarely catastrophic, but it is rarely zero, and it is almost always unexpected. Owners who rented a home before it became their residence, rather than after, face an additional wrinkle: the period of rental use before the home became a primary residence can be "nonqualified use" that proportionally reduces the Section 121 exclusion itself. That interaction is genuinely complex and is one of the clearest cases for a CPA's review before a sale.

How it is reported, and the rate that actually applies

The sale of a rental property is reported on Form 4797, Sales of Business Property, rather than the Schedule D path a primary-residence sale follows.4 Because a house is Section 1250 property, the depreciation portion flows through the Unrecaptured Section 1250 Gain Worksheet in the Schedule D instructions, which is where the 25% maximum rate is applied. The remaining capital gain is reported on Schedule D and Form 8949.

The "25%" figure is a ceiling, not a flat rate. Unrecaptured Section 1250 gain is taxed at the seller's ordinary income rate, but capped at 25%. A seller whose ordinary marginal rate is 22% pays 22% on the recaptured portion. A seller in the 32% or 35% bracket pays 25%, the cap. The recapture is added to taxable income for the year, which can also affect other thresholds.

Two other layers can apply. Higher-income sellers may owe the 3.8% Net Investment Income Tax on the gain, recapture included. And most states tax the gain as well, at rates that vary widely; the combined federal-plus-state-plus-NIIT cost on the recaptured portion can reach the high 20s or low 30s as a percentage.

Deferring recapture with a 1031 exchange

For an owner selling an investment property and buying another, a Section 1031 like-kind exchange can defer both the capital gain and the depreciation recapture. The deferred tax is not erased; it is carried forward into the basis of the replacement property, where it comes due if that property is later sold without another exchange.

The mechanics are strict. A 1031 exchange has firm deadlines (a replacement property must be identified within 45 days and the purchase completed within 180 days), requires a qualified intermediary to hold the proceeds, and applies only to real property held for investment or business use. It does not apply to a primary residence. A home that has been converted to a rental may be eligible, but the intent and holding-period requirements are exacting, and the eligibility question is one to settle with a tax professional well before a sale, not after.

The questions worth asking

Depreciation recapture is predictable. Unlike a market price or a future interest rate, the recapture figure on a given property is a known quantity, the cumulative depreciation taken or allowable, taxed at a rate of no more than 25%. The reason it surprises sellers is not that it is unknowable; it is that nobody calculated it until the closing statement was already drafted.

A seller of a property that was ever rented, even briefly, even to a family member at below-market rent, has a few questions worth surfacing well before listing. How many years was the property a rental, and how much depreciation was deducted or allowable across them? Was the depreciation actually claimed each year, or is there a Form 3115 catch-up question? Does the Section 121 exclusion apply to the appreciation, and does any nonqualified-use period reduce it? The licensed professional who can answer all of these, and turn them into a number, is a CPA, and the conversation is far cheaper to have before the sale than after.
