Installment sale taxes: how Section 453 helps sellers who carry
Last updated 2026-07-17
An installment sale under IRS Section 453 lets a seller who finances their own sale recognize capital gain proportionally as payments arrive, instead of all in the year of sale. Each payment is split between return of basis, capital gain, and interest income, spreading the tax bill across the life of the note.
Why this matters to long-time owners
A landlord who bought decades ago often faces a large gain, plus depreciation recapture, if they sell for cash. Recognizing all of it in one tax year can stack the gain into higher brackets and trigger surtaxes. Carrying the sale as an installment note spreads the gain over the years payments are received, which can keep more of it in lower brackets and defer the bill on the balance still outstanding.
One caveat to model with a CPA: true depreciation recapture (depreciation taken beyond straight-line) is recognized in the year of sale even in an installment sale, while the common straight-line portion (unrecaptured Section 1250 gain, taxed at up to 25 percent) is generally reported as payments arrive. Sellers with heavy depreciation should run both pieces before choosing terms.
The income side of the trade
Beyond deferral, the note itself is the product: monthly payments at an interest rate the parties negotiate, secured by a first lien on a property the seller knows intimately. For a retiring landlord, that often reads as the same monthly income the rental produced, without tenants, repairs, or vacancies. The balloon then delivers the remaining principal in a planned year rather than a surprise one.
None of this is tax advice; the point is that Section 453 is the structural reason seller financing keeps coming up in exit conversations with long-tenure, free-and-clear owners.
Frequently asked questions
Does an installment sale eliminate capital gains tax?
No. It spreads the gain across the years payments are received, which can lower the total effective tax and defers most of the bill, but the gain is still recognized as payments arrive.
Is depreciation recapture deferred in an installment sale?
It depends on the type. Depreciation taken beyond straight-line is recaptured in the year of sale regardless of the installment method. The common straight-line portion (unrecaptured Section 1250 gain) is generally reported as payments arrive, taxed at up to 25 percent. Model both pieces with a CPA.
Who benefits most from an installment sale?
Long-tenure owners with large embedded gains who want income rather than a lump sum, and who own the property free and clear so they can carry the note without a lender payoff.
