What if my condemnation award is paid in installments under section 1033?

Gain is realized when the running total of payments passes your basis, not when the award is final

A staged award is common: a deposit at the taking, a further payment when the appraisal is agreed, and a final sum after a hearing or settlement. For tax purposes none of that matters until the money you have received, or have the right to withdraw from a court deposit, exceeds the adjusted basis of what was taken. Publication 544 says a cash-basis owner realizes gain at that point, and that partial and advance payments count.

Hypothetically, a calendar-year owner with a $400,000 adjusted basis in a condemned commercial lot receives $300,000 in 2026, $250,000 in 2027 and $200,000 in 2028. The running total passes basis in 2027, so 2027 is the first year in which any part of the gain is realized. Under section 1033(g)(4) the three-year period for condemned investment real property runs from the close of 2027 and ends on December 31, 2030. The 2028 payment does not move that date.

The period's start is separate: section 1033(a)(2)(B) opens it on the disposition or, if earlier, the first threat of condemnation, so you can buy before the first dollar arrives. What counts as a threat of condemnation explains that date.

The replacement must cost at least the whole award, including payments that have not arrived

Section 1033(a)(2)(A) recognizes gain to the extent "the amount realized upon such conversion" exceeds the cost of the replacement. The amount realized is the net award: Publication 544 has you subtract "the expenses of obtaining a condemnation award, such as legal, engineering, and appraisal fees", and it adds back amounts the authority pays directly to a mortgage or lien holder, which "are part of your award".

In the hypothetical above the owner has received $550,000 by the time the period's end date is fixed but will eventually receive $750,000. To defer the whole gain the replacement must cost at least $750,000 less the costs of obtaining the award. Buying a $600,000 property in 2028 because that is what had been paid so far would leave the shortfall taxed when the last installment lands. Model the full award, not the cash on hand, and check the arithmetic with your CPA.

Interest the authority pays because payment was late is not part of this calculation at all. Publication 544 treats it as ordinary income reported separately, so it is taxed as it is received and does not raise the replacement target.

Installments do not buy a longer replacement period, but an extension application might

The period is fixed by the first gain year, however many payments follow. If a slow condemnor leaves you with the bulk of the money arriving late in the window, the remedy is the extension in section 1033(a)(2)(B)(ii), not a recalculation of the deadline.

Reg. section 1.1033(a)-2(c)(3) requires the application to be filed before the period expires unless you show reasonable cause for filing late and file within a reasonable time afterwards, and it grants nothing unless you "can show reasonable cause" for not replacing in time. Publication 544 adds that extensions "are usually limited to 1 year", that "the high market value or scarcity of replacement property isn't sufficient grounds", and that the request "must contain all the details describing why you need the extension". Requests go by mail to Internal Revenue Service, 985 Michigan Ave., Stop 16, Detroit, MI 48226, or by fax to 877-477-9193, under the subject line Publication 544 prescribes.

The payment schedule is something to describe in the request, with dates, not something that changes the rule. The replacement property rules and timeline page covers the standard the replacement must meet.

If you do not elect deferral, the installment method is a separate question for your CPA

Some owners decide not to replace. Their award is then a taxable disposition, reported on Form 4797 for business or investment property, and the question becomes whether a multi-year award can be reported under the installment method. Section 453(b)(1) defines an installment sale as a disposition "where at least 1 payment is to be received after the close of the taxable year" of the disposition, which a staged award resembles; section 453(i) requires any recapture income to be recognized in the year of disposition whatever the payment schedule.

Neither Publication 544 nor Publication 537 addresses a condemnation award paid over several years by name in the text opened for this page, so treat the installment method as a question to put to your CPA rather than a settled route. 1031 versus an installment sale sets out the trade-offs that apply when the choice is available.

What to do in the year the first payment above basis arrives

Work out the adjusted basis of the taken property before the first payment, so you know which year will be the gain year. Report the conversion's details on that year's return and leave the gain out of income, which under Reg. section 1.1033(a)-2(c)(2) is how the election is made; reporting a condemnation under section 1033 covers the forms and the statement.

Keep a schedule of every payment, every fee and every amount the authority sent to a lender, because the final amount realized is only known when the last installment clears and the replacement cost has to be measured against it. Property taken by eminent domain is the page for the broader decision about what to buy.

A DST subscription can close quickly late in the window, but a trust closes when its equity is raised, the interest cannot be sold readily afterwards and the equity is at risk. Whether a trust interest is replacement property under section 1033 is unresolved; DSTs for 1033 proceeds sets out the gap, and it belongs with your tax counsel.
