How are structured installment sale payments taxed?
Each payment has three parts. Principal splits into basis recovery and gain at your gross profit ratio, with unrecaptured §1250 gain reported first. The interest portion is ordinary income and net investment income. You file Form 6252 for every year you receive a payment, using the same ratio throughout.

What are the three parts of each payment?
The split of principal is fixed at closing by the gross profit ratio: gross profit divided by contract price (Temp. Treas. Reg. §15a.453-1(b)(2)). If §1245 or other recapture was taxed in the year of sale under IRC §453(i), it is added to basis first, so it is not taxed again in the payments. The ratio does not change over the life of the contract, and it applies to the cash at closing as well as to every later payment. There is no "basis first" option.

The interest is separate from the ratio. It is the price of waiting, set in the annuity contract that funds the payments, and it is taxed as ordinary income in the year you receive it. Your CPA also confirms that the stated interest is adequate under IRC §§483 and 1274; otherwise part of the principal is recharacterized as interest.
In what order does the gain come out?
Treas. Reg. §1.453-12 requires the unrecaptured §1250 gain (the straight-line depreciation on a building) to be reported before the lower-taxed capital gain. So the early payments of a real estate sale carry the 25%-ceiling layer, and the later payments carry 15% or 20% gain. A projection that shows the same blended tax every year is not following the regulation.
What does one year's payment look like?
Illustrative facts, carried over from the year-one example: a $3,000,000 commercial building, adjusted basis $1,000,000, $150,000 of §1245 recapture taxed at closing, $600,000 of unrecaptured §1250 gain, and $1,250,000 of other capital gain. Gross profit for the installment method is $1,850,000, so the gross profit ratio is 61.67%. The seller took $500,000 at closing, which carried $308,333 of §1250 gain. That leaves $291,667 of §1250 gain for the structured payments. The structure pays $250,000 of principal a year for 10 years.
Year two's principal carries $154,167 of gain, all §1250. That leaves $137,500. Now take year three, and assume the contract's interest portion that year is $40,000 (an illustrative figure, not a rate quote).
Tax on that year's payment, on top of $150,000 of other taxable income for a married couple filing jointly (federal, 2026 married-filing-jointly brackets, Rev. Proc. 2025-32; state tax extra):
- Federal income tax on the added income: about $43,900. The interest and the §1250 gain fill the 22% and 24% brackets; the $16,667 of capital gain is taxed at 15%.
- NIIT: MAGI of about $344,200 is $94,200 over the $250,000 threshold, so about $3,600.
- Total: about $47,500 on $290,000 received.
From year four on, each payment's gain is all 15% or 20% capital gain, and the yearly tax drops. Across the whole contract the gain reported adds up to $308,333 + 10 x $154,167 = $1,850,000, which is the gross profit. Nothing escapes; it is deferred and spread.
What do I file each year?
- Form 6252 for the year of sale and every year you receive a payment, using the gross profit percentage from the year of sale. See the Form 6252 walkthrough.
- Form 4797 for the §1245 recapture and the §1231 character of business or rental property, and Schedule D for the capital gain.
- The interest goes on your return as interest income; the payer sends an information return for it.
- If the face amount of your installment obligations from sales over $150,000, outstanding at year end, exceeds $5,000,000, the §453A interest charge applies to the deferred tax.
IRS Pub 537 covers the installment method in plain language. A CPA working the file for the first time should start with the §453 CPA guide.
Frequently asked
Q: Is the interest on a structured sale taxed as capital gain? A: No. The interest portion is ordinary income in the year received, and it counts as net investment income for the 3.8% NIIT. Only the gain portion of principal gets capital gain rates.
Q: Can I change my gross profit ratio later? A: No. It is fixed in the year of sale and applies to every payment. It changes only if the selling price itself is later adjusted, which your CPA would handle.
Q: Why is my tax higher in the early years? A: Unrecaptured §1250 gain, taxed at up to 25%, is reported first under Treas. Reg. §1.453-12. Once that layer is used up, later payments carry 15% or 20% gain.
Q: Do I file Form 6252 every year? A: Yes, for the year of sale and each year you receive a payment on the obligation.

Find out what your sale is really going to cost you in tax, and what you can do about it
No retainer. On a funded structure, the insurer pays a one-time commission of about 4% of the amount structured to the brokerage firm that places it (Hans’s share is about 2.4%; no trail). It is built into the annuity pricing, not a separate fee.
Send me the sale price and roughly what you paid. Within one business day I’ll come back with the number you’re actually looking at and whether a structured installment sale can push it down. If it can’t, I’ll say that just as plainly.
