Selling Late in the Year: 1031 Tax-Year Straddles and Installment Treatment

By default, a November sale that fails in February is taxed in the February year

Section 453 would normally treat a qualified intermediary as your agent, making the buyer's cash a payment to you on the sale date. Reg. §1.1031(k)-1(j)(2)(ii) switches that off: for §453 purposes the intermediary is not your agent, so you receive payment only when it actually delivers cash to you. Example 3 of the regulation walks through a December 1 sale where no replacement is ever bought, and the $40,000 gain is reportable the following year under the installment method.

The regulation reaches the same result whether the exchange fails completely or finishes with leftover cash. In Example 2 an $80,000 replacement closes on March 11 and the $20,000 left over is delivered the same day, and that $20,000 of gain is reported in the March year.

The rule stops applying at the earlier of the end of the exchange period or the moment you gain an unrestricted right to the money. If your exchange agreement lets the intermediary release funds on day 46 because nothing was identified, and day 46 falls before December 31, the payment lands in the sale year and there is no straddle.

The bona fide intent test is judged on closing day, not on whether you bought

Reg. §1.1031(k)-1(j)(2)(iv) grants payout-year treatment only if, at the beginning of the exchange period, it was reasonable to believe like-kind replacement property would be acquired before the period ended. The facts on the closing date control, and Example 3 makes the point that a taxpayer who never identifies anything still qualifies if the intent was genuine when the sale closed.

What defeats the test is evidence that the exchange was a placeholder: an exchange agreement signed with no search under way, a replacement market you had already rejected, or contract terms that made closing impossible. Keep the dated identification notice, broker correspondence and offers as the file that proves the intent existed.

Selling property that was not held for investment or business use also removes the treatment, because paragraph (j)(2)(v) excludes disqualified property.

Worked example: a November 3, 2026 closing whose replacement collapses in February 2027

Assume a hypothetical unencumbered rental sold for $1,000,000 on November 3, 2026, with an adjusted basis of $400,000 after $150,000 of straight-line depreciation. Day 45 is December 18, 2026 and day 180 is May 2, 2027; because May 2 falls after the April 15 return due date, a Form 4868 extension is needed to keep the full period, since §1031(a)(3)(B) ends the exchange period at the unextended due date.

You identify one building by December 18, its seller walks away on February 10, 2027, and the intermediary returns $1,000,000 in March 2027. The realized gain is $600,000, of which $150,000 is unrecaptured §1250 gain; nothing is ordinary recapture because straight-line depreciation creates no additional depreciation under §1250(b)(1).

Default reporting: Form 8824 goes with the 2026 return to show the transfer, and the $600,000 is reported on Form 6252 with the 2027 return as installment income received in 2027. Reg. §1.453-12 then takes the $150,000 unrecaptured §1250 gain into account before the 15% or 20% layer.

• 2026 return: Form 8824, the extension that preserved day 180, and no gain unless you elect out.
• 2027 return: Form 6252 for the payout, flowing to Form 4797 and Schedule D, with the recapture layer first.
• Either year: the 3.8% net investment income tax on Form 8960 follows the year the gain is recognized.

Why the year matters: the same $600,000 gain costs $128,087 or $114,315 in this hypothetical

Suppose the sellers file jointly with $150,000 of other taxable income in 2026 and $60,000 in 2027 after retiring. Using the 2026 thresholds in Rev. Proc. 2025-32 for both years (2027 amounts will be indexed), the $150,000 recapture layer is taxed at ordinary rates capped at 25%, the $450,000 balance at 15% up to $613,700 of taxable income and 20% above, and §1411 adds 3.8% on the lesser of the gain or MAGI over $250,000.

Reported in 2026, the layers come to $34,772 on the recapture, $74,315 on the capital gain ($313,700 at 15% and $136,300 at 20%) and $19,000 of NIIT, or $128,087. Reported in 2027 with less other income, they come to $28,920, $69,815 and $15,580, or $114,315.

The straddle saved $13,772 here purely by landing the gain in a lower-income year, on top of a year's deferral of the payment. Run the same layers for your own income in each year before deciding whether to leave the default in place.

Two items stay in the sale year: net debt relief and ordinary recapture

If your buyer paid off or assumed your mortgage and the exchange later fails or completes with less debt, the relief is money received when the relinquished property closed. Rev. Rul. 2003-56 holds that in a straddling exchange the excess of relinquished debt over replacement debt is money received in the first year and the gain on it is recognized then, and Pub. 537 treats a mortgage above your basis as a year-of-sale payment for installment purposes.

Ordinary recapture cannot be deferred at all: §453(i) requires recapture income to be recognized in the year of disposition whether or not a payment was received. That bites on §1245 components from a cost segregation study or bonus depreciation; straight-line real property produces only the 25%-capped unrecaptured §1250 gain, which does follow the payment.

A partnership that sells in year one and buys with less debt in year two has the same problem, and under Rev. Rul. 2003-56 the net decrease in liabilities is also a deemed §752(b) distribution to the partners at the end of year one.

Electing out under §453(d) when the sale year is the cheaper year

You elect out by not filing Form 6252 and reporting the full gain on Form 4797 or Form 8949 with the sale-year return by its due date including extensions. The Form 6252 instructions add that a timely original return filed without the election can be amended within six months of the unextended due date with 'Filed pursuant to section 301.9100-2' at the top, and Pub. 537 notes that once made the election is revoked only with IRS approval.

Electing out makes sense when the sale year has unusually low income, when you hold suspended passive losses or an expiring capital loss, or when you expect your income or the rates to rise. It also removes §453A exposure: if the intermediary's obligation is outstanding at year-end and your installment obligations from the year exceed $5,000,000 in face amount, interest is charged on the deferred tax.

Filing the sale-year return with the gain on it is the election, so a return prepared on autopilot can lock in year-one recognition by accident. Tell your preparer which year you want before the return is drafted.

Five moves before December 31 if a late-year exchange looks shaky

Confirm the timing rules with your CPA or attorney before relying on them, since the intent test and the debt-relief split are fact-specific.

• Identify by day 45 even if closing is uncertain; funds released on day 46 for lack of identification may arrive in the sale year and end the straddle, and a DST backup identification keeps the exchange itself alive.
• File Form 4868 for any sale closing on or after October 18, 2026, because day 180 then falls after April 15, 2027; see whether an extension keeps your 180 days.
• Assemble the intent file now: the exchange agreement, identification notice, offers and lender correspondence dated before and after closing.
• Model both years' tax with the layers above, then decide whether to let the default stand or elect out on the sale-year return.
• Check the §453A threshold and the year-one debt relief, since those two numbers decide how much of the gain can move at all.
• Read what happens when an exchange fails and the Q4 deadline traps for the non-tax steps.
