Updated July 29, 2026. Quick answer: The installment method spreads gain as payments arrive — but not all of it. IRC §453(i)(1) recognises recapture income in the year of disposition, “notwithstanding subsection (a),” and §453(i)(2) measures it as if every payment you will ever receive had arrived that year. So the first tax bill can exceed the first cash payment.
The override
Recapture jumps the queue, and the statute says so in one word. IRC §453(i)(1): “In the case of any installment sale of property to which subsection (a) applies— (A) notwithstanding subsection (a), any recapture income shall be recognized in the year of the disposition, and (B) any gain in excess of the recapture income shall be taken into account under the installment method.” And §453(i)(2) measures it on a fiction: recapture is the amount that would be ordinary income under §1245 or §1250 “if all payments to be received were received in the taxable year of the disposition.”
Two things follow that no summary carries. First, the ordering: recapture comes out first and only “any gain in excess of the recapture income” goes onto the installment method. Second, the measuring fiction applies to a deal in which, by definition, the money has not arrived. An asset sale heavy in depreciated equipment can therefore produce an ordinary-income bill in year one against a small down payment.
The §751 cross-reference widens it. §453(i)(2) reaches ordinary income under §1245 or §1250 “or so much of section 751 as relates to section 1245 or 1250” — which pulls partnership interests into the same year-one treatment. If you are selling an interest rather than assets, this is the provision to have looked at before signing.
| Component | When taxed | Authority |
|---|---|---|
| Recapture income | Year of sale, in full | §453(i)(1)(A) |
| Gain above recapture | As payments are received | §453(i)(1)(B) |
| Interest on the note | As received, as ordinary income | §453 generally |
| The deferral itself | Carries an annual charge above the threshold | §453A(c) |
Two decisions follow from this and both have deadlines. Electing out closes at the extended return due date, and the deferral you keep is charged for every year it is outstanding.

This states what the cited authority says. It is not tax or legal advice. A business sale turns on the entity type, the deal documents and the allocation actually agreed, none of which a page can see, and the numbers here are structural rather than yours.
