Depreciation Recapture Timing in an Installment Sale

When you sell a rental or business property in an installment sale, the buyer makes payments over multiple years. Your gain recognition is spread across those payment years, but depreciation recapture is an exception: all unrecaptured Section 1250 depreciation must be recognized as ordinary income in the year of sale, even though your total gain is deferred. This creates a timing mismatch that catches many sellers by surprise.

Why depreciation recapture accelerates in an installment sale

An installment sale allows a seller to recognize gain ratably across multiple years as the buyer pays. If you sell a property for $500,000 and the buyer pays $100,000 per year over five years, you recognize one-fifth of the gain in each year. This deferral can lower your tax burden by spreading income across multiple tax years and potentially reducing your marginal rate.

However, the IRS treats depreciation recapture differently. Any depreciation you claimed while owning the property—for example, $120,000 in depreciation deductions over 20 years of ownership—must be recaptured (taxed back as ordinary income) entirely in the year of sale. You do not spread the recapture across payment years.

The economic reason is straightforward: depreciation is a tax deduction you already received and already used to lower your taxes in prior years. The IRS does not want sellers to defer that tax bill indefinitely by spreading it across an installment period. Recapture accelerates to ensure you account for the value of the depreciation deduction in the sale year itself.

Section 1250 versus Section 1245 recapture

Section 1250 recapture applies to real property (land and buildings). For residential real estate placed in service after 1986, only the excess of accelerated depreciation over straight-line depreciation is recaptured; for buildings placed in service before 1987, depreciation deductions may trigger recapture at ordinary rates. In practice, most residential real estate qualifies for the lower “unrecaptured Section 1250 depreciation” rate—currently taxed at a maximum of 25%.

Section 1245 recapture applies to personal property (machinery, equipment) and applies to all depreciation, not just accelerated amounts. If you sell business equipment in an installment sale, all prior depreciation is recaptured at ordinary rates in the year of sale.

For a typical rental property (building plus land), you are dealing with Section 1250 treatment, and recapture is taxed at the Section 1250 rate (up to 25%), not at your ordinary marginal rate.

How the calculation splits recapture and gain

On the sale date, you calculate the total realized gain (sale price minus adjusted basis). Then you separate that gain into two components:

1. Unrecaptured depreciation (or recapture gain): Depreciation you claimed over the holding period. This is recognized in the year of sale and taxed at the Section 1250 rate (max 25% for residential property).

2. Capital gain (or excess gain): Any remaining realized gain after subtracting the recapture amount. This is allocated across the installment period using the installment method.

Example of recapture acceleration

You sell a residential rental property with the following facts:

• Original purchase price: $300,000
• Depreciation claimed over 25 years: $150,000
• Adjusted basis at sale: $150,000 ($300,000 − $150,000)
• Sale price: $500,000
• Total realized gain: $350,000 ($500,000 − $150,000 basis)
• Buyer pays: $100,000 down, then $100,000 per year for four years

Recapture in Year 1 (year of sale):

• Unrecaptured Section 1250 depreciation: $150,000 (all prior depreciation)
• This is recognized and taxed at 25% (max), generating tax of $37,500

Capital gain recognized Year 1:

• Remaining gain after recapture: $350,000 − $150,000 = $200,000
• Gross profit percentage: $200,000 ÷ $500,000 = 40%
• Buyer paid $100,000 in Year 1
• Capital gain recognized: $100,000 × 40% = $40,000 (taxed at 15% or 20%)

Capital gain recognized Years 2–5:

• Each year, the buyer pays $100,000
• Gain recognized each year: $100,000 × 40% = $40,000

In Year 1, you recognize $150,000 in recapture income and $40,000 in capital gain. The buyer’s down payment carries a much higher proportion of recapture income than the later annual installments. The recapture income is fully front-loaded into the sale year, while the capital gain is ratably spread.

The buyer’s assumption of existing debt

If the seller owes a mortgage or other debt that the buyer assumes or takes subject to, that assumed liability counts as payment received in the year of sale for purposes of calculating the gain-recognition percentage and is also treated as a payment for recapture purposes.

Suppose in the above example the property also had a $200,000 mortgage that the buyer assumed. The total consideration would be:

• Down payment: $100,000
• Assumed mortgage: $200,000
• Future installment payments: $400,000 (over four years)
• Total consideration: $700,000

The gain-recognition percentage would be $200,000 ÷ $700,000 = 28.57%, and the recapture would still be fully recognized in Year 1 (not spread). This ensures that the seller cannot defer both gain and recapture by using debt assumption as a financing mechanism.

Interaction with passive activity loss rules

If you have suspended passive activity losses from the rental property being sold, those losses are finally released in the year of sale. They are deducted against the recapture income and the capital gain in that year. The timing mismatch between recapture (all in Year 1) and capital gain (spread over years) means the suspended losses may offset the full recapture amount in Year 1, reducing the ordinary-income tax burden while the capital gain spreads over subsequent years.

This can be advantageous, but only if you have accumulated suspended losses. A seller with years of profitable rentals would not have this benefit.

Impact on installment seller financing

Sellers who offer owner financing in an installment sale must be prepared for a large tax bill in the year of sale due to recapture acceleration. If you receive only a 20% down payment and carry back 80% of the price, you receive the full recapture tax bill up front (Year 1) but spread the capital gain payment over the remaining years. This timing mismatch can create cash-flow stress.

Some sellers structure deals to minimize this—for example, by taking a larger down payment or a shorter installment period—to align the cash received with the tax liability. A tax professional can model these scenarios before signing a purchase agreement.
