Structured installment sale vs 1031 exchange: how each one handles the tax

Short answer: A 1031 exchange postpones the tax only if you reinvest in more real estate on a 45-day and 180-day clock, while a structured installment sale spreads the tax over the years you are paid and needs no replacement property. In the $1,000,000 example below, selling for cash adds $113,313 of federal tax, the 1031 adds nothing now, and a 10-year structured sale adds $25,089 spread over ten returns.

Two different ideas

A 1031 exchange (IRC 1031) keeps your money in real estate. A qualified intermediary holds the sale proceeds, you name replacement property within 45 days and close within 180, and the gain is postponed. Your old basis carries into the new property, so the tax waits there until a later taxable sale, or disappears if the property is held until death and gets a stepped-up basis.

A structured installment sale takes your money out of real estate. The buyer pays the full price at closing, but before closing you agree to receive your share as scheduled payments from a third-party assignment company, which funds them with a contract from a life insurance company. Because you never had the cash, the gain is reported under the installment method (IRC 453) as payments arrive.

A worked example

Assumptions: a married couple filing jointly, $60,000 of other ordinary income each year, no state income tax. They sell a rental for $1,000,000 with an adjusted basis of $400,000 after $200,000 of depreciation. The gain is $600,000: $200,000 of unrecaptured Section 1250 gain and $400,000 of long-term capital gain.

Federal tax added by the sale under 2026 law. Interest in the payments is taxed separately and shown on its own row.

Figures are the federal income tax and 3.8% net investment income tax added by the sale, computed with 2026 federal brackets (IRS Rev. Proc. 2025-32) held flat for every payment year, standard deduction applied, no state tax. The 6% payout rate is an assumption for illustration, not a quote or an offer.

Why spreading lowers the bill: the tax rates do not change. What changes is how much gain lands on one return. One large year pushes most of the gain into the 20% bracket and over the $250,000 threshold for the 3.8% NIIT. Smaller yearly slices stay in the 0% and 15% brackets.

Depreciation recapture

The $200,000 of depreciation taken over the years is taxed at your ordinary rate, capped at 25% (IRC 1(h)(6)). In an installment sale it is reported first, before the rest of the gain (Treas. Reg. 1.453-12). Depreciation on equipment and other Section 1245 property is different: it is taxed in the year of sale even when payments are spread (IRC 453(i)). See the guide to unrecaptured Section 1250 gain.

Does the interest change the answer?

The payments include interest, and interest is taxed as ordinary income. A fair comparison lets the cash seller invest the after-tax proceeds at the same 6% and pay tax on that interest too. On that basis, after 10 years the structured seller has $1,541,473 and the cash seller $1,490,370, a gap of $51,102. A higher return on the invested cash would narrow it or reverse it.

Combining the two

A seller who wants some real estate but not all of it can exchange part of the proceeds and take the rest as a structured sale. The part not reinvested is boot, taxed up to the gain (IRC 1031(b)); if it is paid in installments arranged before closing, it is reported as it arrives (IRC 453(f)(6)). Here, $300,000 of boot would add $56,208 of tax as cash at closing, or $23,999 spread over 10 years.

Costs and risks to weigh

Gray areas

Reasonable tax professionals disagree on these points. Both views are shown; neither is a recommendation.

Is the seller in constructive receipt?

One view: If the buyer's obligation is assigned to a third party under terms signed before closing, and the seller has no right to the funds, the installment method applies. Constructive receipt requires money the seller could draw on (Treas. Reg. 1.451-2).

The other view: No revenue ruling or regulation addresses this structure by name, so the IRS could argue the seller had the economic benefit of the cash at closing.

Common ground: The terms must be set before closing, and the seller must not hold, pledge or direct the funding asset.

How is boot gain split in a combined deal?

One view: Treat recognized boot gain as recapture first, up to the depreciation taken. The example above uses this conservative view.

The other view: Allocate the recognized gain pro rata between recapture and long-term gain, which lowers the tax.

Common ground: The boot is taxable up to the gain either way; only the rate mix differs.

Frequently asked questions

What is a structured installment sale?

An installment sale where the buyer pays in full at closing and a third-party assignment company makes the scheduled payments to the seller. The gain is reported under IRC 453 as payments arrive.

Do I need to buy another property?

For a 1031 exchange, yes, within 45 days to identify and 180 days to close. A structured installment sale needs no replacement property.

Can a failed 1031 exchange be turned into a structured sale?

Only if the structured terms were in place before the seller had a right to the money. After the intermediary releases the funds, it is too late.

Is depreciation recapture spread too?

Straight-line depreciation on a building (unrecaptured Section 1250 gain) is spread and reported first. Section 1245 recapture is taxed in the year of sale (IRC 453(i)).

Are the payments taxed?

Each payment has three parts: tax-deferred return of basis, gain taxed as capital gain or recapture, and interest taxed as ordinary income.

What happens if the seller dies during the payments?

The payments continue to the beneficiaries, who pay tax on the remaining gain as it arrives (IRC 691). There is no step-up in basis on it.
