The rule: recapture in year one
IRC Section 453(i) requires that depreciation recapture income — Section 1245 recapture on personal property and cost-segregation 5-, 7-, and 15-year components, plus any Section 1250 'additional depreciation' left over from accelerated methods — be recognized in the year of sale, regardless of when the buyer's installment payments arrive. You cannot spread that ordinary-income recapture over the life of the note. Only the gain above the recapture-income amount qualifies for installment sale deferral under Section 453. (As the next section explains, the 25% 'unrecaptured Section 1250 gain' on straight-line real estate is treated differently from this ordinary recapture — it is deferrable, but reported first as payments arrive.)
This is the critical limitation of installment sales for rental investors: if your accumulated depreciation is large relative to your total gain, little or nothing is deferrable, and you face a significant tax bill in year one even though you received only a down payment.
How the math works
Example: adjusted basis $100,000, depreciation claimed $200,000, original cost $300,000. Sell at $500,000 on a 5-year installment note, receiving $100,000 down and $80,000/year for five years.
Total gain: $500,000 − ($300,000 − $200,000) = $400,000. Assume the $200,000 of depreciation here is Section 1245 ordinary recapture (from equipment or cost-segregated components) — so it is taxed at your ordinary rate and recognized entirely in year one. Capital gain above recapture: $200,000 (deferrable via installment). Under Section 453(i) the recognized recapture is added to basis for the installment computation, so gross profit = $400,000 − $200,000 = $200,000 and the gross profit ratio is $200,000 ÷ $500,000 = 40%. Each $80,000 annual payment then includes $32,000 of deferred capital gain (40% × $80,000) reported over the 5-year period. But the $200,000 recapture is all reported in year one regardless. (If instead this were ordinary straight-line depreciation on the building itself, the $200,000 would be unrecaptured Section 1250 gain — capital gain spread across the payments, not accelerated; see below.)
When installment sales still make sense despite recapture
Even if you must report all recapture in year one, deferring the capital gain portion can still be valuable — especially if it keeps your total income below the 20% capital gains threshold or below the NIIT threshold in subsequent years. The key is to have enough liquidity from the down payment to cover the year-one recapture tax bill. Model the cash flow carefully: you need to pay the IRS more tax than you received in cash in year one if the down payment doesn't cover the recapture tax.
Which 'recapture' accelerates — and which does not
The single most misunderstood point here is that not all depreciation is treated the same on an installment sale. Section 453(i) accelerates only ordinary-income recapture: Section 1245 recapture on personal property and on the 5-, 7-, and 15-year components a cost segregation study carved out, plus any Section 1250 'additional depreciation' (the excess of accelerated over straight-line). Because virtually all real property placed in service after 1986 is depreciated straight-line, most buildings generate zero Section 1250 additional depreciation and therefore have no ordinary recapture to accelerate.
So what happens to the straight-line depreciation you took on the building? It becomes unrecaptured Section 1250 gain — a capital gain taxed at a maximum federal rate of 25%. This gain is not forced into year one; it is spread under the installment method as you collect principal. There is an ordering rule, though: as each payment's capital-gain portion is recognized, the unrecaptured 1250 gain is reported first, before any 0%/15%/20% long-term gain, until the full 1250 pool is used up. The practical effect is that the 25% gain is front-loaded within your capital gain but still deferred across the note — a much friendlier result than the year-one hit that true 1245 recapture triggers.
How to report it: Form 6252 and Form 4797
An installment sale is reported on Form 6252 each year — in the year of sale and every year you receive a payment. Ordinary depreciation recapture that must be recognized up front (Section 1245, and any Section 1250 additional depreciation) is figured on Form 4797, Part III in the year of sale and flows to your return as ordinary income that year, whether or not you received cash to cover it.
That recognized recapture is then added to your basis on Form 6252 when you compute the gross profit percentage, which is why it does not get double-counted in the deferred gain. The remaining gain — including any unrecaptured Section 1250 gain — is carried on Form 6252 and reported as capital gain on Schedule D as payments come in, with the Schedule D worksheet applying the 25% rate to the 1250 portion in the order described above. The stated interest (or imputed interest under the original-issue-discount rules if the note's rate is too low) is separately reported as ordinary interest income each year.
A year-by-year cash-and-tax view
Return to the numbers above — $500,000 sale, $100,000 down, $80,000 per year for five years, $200,000 of Section 1245 ordinary recapture, and $200,000 of deferrable capital gain at a 40% gross profit ratio — and watch the cash line. In year one you collect $100,000 of principal but must report the entire $200,000 of ordinary recapture plus 40% of the $100,000 payment ($40,000 of capital gain). If your ordinary rate is 32% and your capital gain rate is 20%, that is roughly $64,000 + $8,000 = $72,000 of federal tax on $100,000 of cash — before state tax. The recapture front-loads the pain precisely when you have the least cash.
In years two through five, each $80,000 payment carries only $32,000 of capital gain (40% × $80,000) and no further recapture, so the tax drops to roughly $6,400 of federal capital gains tax per year plus tax on the interest. The lesson is not that installment sales are bad — it is that you must reserve for the year-one recapture out of the down payment or other funds, because the IRS does not wait for the note to pay out. If the deal cannot produce a down payment large enough to cover that first-year tax, either renegotiate the terms or reconsider a 1031 exchange.
The Section 453A interest charge on large sales
High-dollar sellers face an extra cost. Under IRC Section 453A, if your outstanding installment obligations from sales of property for more than $150,000 exceed $5 million at year end (aggregated for the year, with a married-filing-separately threshold of $2.5 million), you owe an annual interest charge on the deferred tax attributable to the balance above $5 million. The charge is computed at the IRS underpayment rate and reported as additional tax — it effectively prices the time-value benefit of deferral. Personal-use property and most farm property are excepted. If your sale is large, model this charge before assuming the installment method saves money.
Electing out of the installment method
You are not required to use the installment method — it applies automatically, but you can elect out under Section 453(d) on a timely filed return (including extensions) for the year of sale. When you elect out, you report the entire gain in the year of sale, valuing the buyer's note at its fair market value. Electing out can make sense when you expect capital gains rates to rise, when you have current-year capital losses or a large NOL to absorb the gain now, or when the buyer's creditworthiness makes collection uncertain and you would rather not report gain you may never receive. The election is generally irrevocable without IRS consent, so run the projection first.
Buyer default, repossession, and planning tips
If the buyer defaults and you repossess the real property, Section 1038 generally limits the additional gain you recognize on repossession and lets you take the property back with a basis adjustment rather than triggering full tax — a valuable protection, but one with its own computation. Beyond that, three planning moves matter most: (1) size the down payment so it at least covers the year-one ordinary recapture tax, since that liability arrives whether or not cash does; (2) if your goal is to defer all gain — recapture included — a 1031 exchange does that where an installment sale cannot; and (3) remember that most states tax installment gain too, and a few decouple from the federal timing, so confirm your state's treatment before you structure the note.
Frequently asked questions
Can I defer depreciation recapture with an installment sale?
Ordinary recapture cannot be deferred: under IRC 453(i), Section 1245 recapture (and any Section 1250 additional depreciation) is recognized in full in the year of sale. But the ordinary straight-line depreciation on a building becomes 'unrecaptured Section 1250 gain' — a 25%-rate capital gain that IS spread under the installment method, though it is reported first among your capital gain as payments arrive.
What if the down payment is less than my recapture tax?
You will owe more in taxes in year one than you received in cash. You need to have other funds available to pay the tax, or negotiate a larger down payment to cover the estimated recapture liability.
Is a 1031 exchange better than an installment sale for deferring recapture?
Yes. A 1031 exchange defers all gain including all recapture. An installment sale defers only the capital gain above recapture, while recapture is taxable immediately.
What forms do I file for an installment sale of a rental?
Form 6252 reports the installment sale in the year of sale and every year you collect a payment. Any Section 1245 or Section 1250 ordinary recapture is figured on Form 4797, Part III, in the year of sale. The deferred capital gain (including unrecaptured Section 1250 gain) flows to Schedule D as payments are received, and the note's interest is reported as ordinary interest income.
Is there an extra tax for very large installment sales?
Yes. Under Section 453A, if your outstanding installment obligations from sales over $150,000 exceed $5 million at year end, you owe an annual interest charge (at the IRS underpayment rate) on the deferred tax attributable to the excess. Personal-use and most farm property are exempt.
Can I choose not to use the installment method?
Yes. You can elect out under Section 453(d) on a timely filed return and report the full gain in the year of sale, valuing the buyer's note at fair market value. This can help if you expect higher future rates, have current losses to absorb the gain, or doubt the buyer will pay. The election is generally irrevocable.
