Seller Financing in a 1031 Exchange: How a Carryback Note Can Ride Along Without Blowing the Deferral
Consider a common scenario. An investor is selling an apartment building for $1,000,000. The buyer can put $700,000 down but needs the seller to carry back the remaining $300,000 as a promissory note, paid over the next several years. The seller is happy to do it — the note earns a good interest rate — but the seller also intends to roll the entire $1,000,000 gain into a replacement property through a 1031 exchange. The question lands on the closing table: what happens to that carryback note inside an exchange?
It is one of the most common — and most misunderstood — situations in exchange practice. Handled carelessly, the note becomes taxable boot and the seller recognizes gain on the financed portion. Handled correctly, the same note can ride along inside the exchange and the full gain stays deferred. This article walks through why seller financing collides with §1031, the rule that keeps the note out of the taxpayer's hands, a technique we use regularly to keep the deferral clean, and the §453 installment-sale mechanics that govern what happens when a note stays outside the exchange.
Why a Carryback Note Collides With §1031
A 1031 exchange defers gain only to the extent the taxpayer reinvests the entire proceeds of the relinquished property into like-kind replacement property and receives nothing else. Anything else the taxpayer receives — cash, debt relief, or other property — is boot, and gain is recognized to the extent of that boot.
A seller-carryback promissory note is "other property." If the taxpayer takes the note directly at the closing of the relinquished property, the IRS treats it as an installment obligation received in the exchange — boot — and the taxpayer must recognize gain on that portion. Worse, because the note is not cash, the taxpayer can end up owing tax on a gain before collecting the money to pay it.
The reason is constructive receipt. The whole architecture of a deferred exchange depends on the taxpayer never having the right to receive the sale proceeds. The moment a note is made payable to the taxpayer, the taxpayer has received something of value from the sale — and a piece of the exchange falls out.
The Core Rule: Make the Note Payable to the Qualified Intermediary
The fix is structural and it must happen before the relinquished property closes: the carryback note is made payable to the qualified intermediary, not to the taxpayer. The QI — not the seller — is the payee, and the security instrument (the deed of trust or mortgage) runs to the QI as well. The note becomes one more asset the QI holds as part of the exchange proceeds, alongside the cash.
This is expressly contemplated by the deferred-exchange regulations. Treas. Reg. §1.1031(k)-1(j)(2) coordinates §1031 with the installment-sale rules of §453 and provides that when a taxpayer's obligation is held within the qualified-intermediary safe harbor, the taxpayer is not treated as being in receipt of payment merely because the note exists. The regulation goes further: if the taxpayer later receives an evidence of indebtedness from the transferee through the QI, it is treated as a note from the person who bought the relinquished property — and its mere receipt is not a "payment" that would break installment treatment.
The practical consequence is that a note payable to the QI does not, by itself, trigger gain. But it is not yet cash — and a 1031 exchange must be completed with the acquisition of like-kind real property, not with a promissory note held by the intermediary. So the note has to be dealt with, one way or another, before the exchange closes. There are several ways to do that.
The Technique We Use: The Taxpayer Buys the Note From the QI at Face Value
Here is the approach we use most often, and it is clean and simple. The note is made payable to the QI at the closing of the relinquished property, exactly as described above. Then, after the relinquished property has closed but before any payment has been made on the note, the taxpayer buys the note from the QI for its full face amount, in cash.
Walk through what that accomplishes in our $1,000,000 example:
- The relinquished property closes. The buyer delivers $700,000 in cash plus a $300,000 note, both payable to the QI. The QI is now holding $700,000 cash and a $300,000 note.
- The taxpayer writes the QI a check for $300,000 — the face amount of the note — and the QI assigns the note to the taxpayer.
- The QI now holds $1,000,000 in cash and uses all of it to acquire the replacement property. The full amount is reinvested, so there is no boot and no recognized gain.
- The taxpayer walks away owning the note. Because the taxpayer paid full face value for it, the taxpayer's basis in the note equals its face amount. As the buyer makes principal payments, the taxpayer simply recovers basis — there is no gain on the principal — and the interest is taxed as ordinary income, exactly as it would be on any investment note.
The elegance is that the taxpayer has effectively converted $300,000 of cash into a note receivable outside the exchange, while the exchange itself is funded with a full $1,000,000 of cash. The deferral is complete, and the taxpayer holds a performing, interest-bearing note purchased at par with no built-in gain.
Two conditions make this work cleanly. First, the taxpayer needs the liquidity to buy the note — $300,000 of outside cash in the example. Second, the purchase should happen before payments begin on the note, so that face value and fair value line up and there is no argument that the taxpayer bought a seasoned note at a discount (which could create its own gain or boot questions). Both are easy to satisfy with a little planning.
Other Ways to Deal With a Note Payable to the QI
Buying the note back is not the only route. Depending on the taxpayer's cash position and the deal, the note payable to the QI can also be handled in these ways:
- Sell the note to a third party for cash. The QI sells the note to an unrelated buyer and uses the cash proceeds toward the replacement property. The caution here is pricing: if the note sells at a discount, the shortfall is generally treated as boot, and the taxpayer recognizes gain to that extent. A note bought back by the taxpayer at par avoids that problem entirely.
- Assign the note to the seller of the replacement property. If the replacement seller is willing to take the note as part of the purchase price, the QI can assign it directly at the replacement closing. The note becomes consideration for like-kind property and stays inside the exchange. This is elegant when it is available but depends on a cooperative replacement seller.
- Let the note pay off during the exchange period. On a short note — say, a six-month carryback — the buyer may pay it off in full within the 180-day window. If the cash reaches the QI in time, it simply funds the replacement purchase like any other proceeds.
- The "hard-money" alternative — skip the carryback entirely. Instead of carrying paper, the taxpayer lends the buyer the shortfall as a separate cash loan outside the exchange. The buyer then closes the relinquished-property purchase entirely in cash, the QI receives a full cash price, and the taxpayer holds a loan that never touched the exchange. This turns the sale into an all-cash transaction and keeps the exchange simple, but it requires the taxpayer to advance the cash up front.
When the Note Stays Outside the Exchange: §453 Installment Treatment
Sometimes a taxpayer wants to keep the carryback note as an installment obligation — for the interest income, or to spread gain over several years — rather than buying it back or forcing it into the exchange. And sometimes an exchange simply fails: the taxpayer cannot identify or acquire replacement property in time, and the note is ultimately distributed back to the taxpayer. In both cases, the note is governed by the installment-sale rules of §453.
Under §453, gain on an installment obligation is recognized as principal payments are received, in proportion to the transaction's gross-profit percentage, rather than all at once in the year of sale. Interest is separately taxed as ordinary income. This is often a favorable result on its own — it spreads the gain and can keep the taxpayer out of the highest brackets in any single year.
The coordination rule in Treas. Reg. §1.1031(k)-1(j)(2) is what makes a failed exchange land softly here. Because the note held by the QI was not a "payment" while the exchange was pending, a taxpayer who had a bona fide intent to complete the exchange at the outset can report the note on the installment method when it comes back — deferring gain on the financed portion until principal is actually collected, often pushing the first dollar of recognized gain into a later tax year. A failed exchange with a carryback note, in other words, is not necessarily a fully taxable event in the year of sale.
The Depreciation-Recapture Trap Inside §453
There is one hard limit that catches taxpayers off guard, and it deserves its own warning. §453(i) requires that depreciation recapture be recognized in full in the year of sale — regardless of the installment schedule and regardless of how little cash is collected that year.
That means the §1245 recapture on personal-property components and the §1250 recapture on real property cannot be spread over the note. Even if the taxpayer collects only interest in year one and no principal at all, the ordinary-income recapture is taxed immediately. Only the gain above the recapture amount gets installment treatment.
The same recapture-first ordering applies when boot shows up in an exchange: any gain the taxpayer is forced to recognize is sourced first against ordinary-income recapture, not against the more favorable capital gain. This is precisely why we prefer to keep the note out of the boot column — through the buy-back or one of the other structures above — rather than let it force recognition of what is often the most expensive, highest-rate slice of the gain.
Planning Checklist for a Carryback Inside an Exchange
When seller financing and a 1031 exchange are going to share a closing table, a handful of decisions made early keep the whole thing clean:
- Decide before closing whether the note goes into the exchange or stays outside it. This cannot be fixed after the relinquished property closes.
- Name the qualified intermediary as payee on the note and the security instrument from the start — never the taxpayer.
- If the taxpayer will buy the note back, confirm the liquidity and do it at face value, before any payments are made.
- Watch for depreciation recapture — it is recognized in the year of sale under §453(i) and is sourced first against any recognized gain. Model it before committing to a structure.
- Mind the deadlines. A note that will be paid off inside the exchange still has to clear before the 180-day period ends.
- Coordinate the QI, the closing agent, and the tax advisor so the note is documented consistently with the chosen structure. A note drafted in the taxpayer's name "for convenience" at closing can undo the entire plan.
A Washington Note
For sellers across the Puget Sound region and Central Washington, seller financing is especially common on farm ground, small commercial buildings, and owner-to-owner deals where conventional financing is slow or expensive. The good news is that even though Washington now has a capital-gains excise tax — and, beginning in 2028, a new 9.9% tax on household income above $1 million (ESSB 6346) — both taxes exclude gains from the sale of real property. A properly structured real-property exchange and carryback therefore generally stay outside them, and the federal treatment drives the analysis. As always, the interest income on a carryback note is ordinary income for federal purposes, and the recapture rules above apply in full.
A carryback note does not have to be the thing that breaks an exchange. With the note payable to the qualified intermediary and a plan for converting or retaining it, seller financing and a 1031 exchange coexist comfortably — and the seller keeps both the deferral and the interest income.
If you are contemplating a sale where you will carry back part of the price and you want to preserve your exchange, the time to structure the note is before the sale closes, not after. We are glad to work through the mechanics with you and your advisors.
