The short answer
Usually yes, if the whole net amount reached an account you control. Under Reg. section 1.1031(k)-1(f), money you actually receive before you receive the replacement makes the transfer a sale 'even though the taxpayer may ultimately receive like-kind replacement property'. Wiring it back, even the same day, does not reverse receipt, and no regulation or revenue procedure offers a cure. If only part of the money reached you, that part is taxable boot and the rest can still finish the exchange.
At a glance
| Full proceeds received | The transaction is a sale, not a deferred exchange |
|---|---|
| Partial proceeds received | That amount is boot; the balance held by the QI can still be exchanged |
| Actual receipt | Occurs when you receive the money or its economic benefit |
| Constructive receipt | Occurs when money is credited to your account or available to draw |
| Returning the wire | No published rule treats a returned wire as never received |
| Same-day repurchase | Still a sale under the Fifth Circuit's Carlton decision |
| Opportunity zone fallback | Capital gain can go into a qualified fund within 180 days of the sale |
Receipt of the full proceeds before you own the replacement turns the exchange into a sale
The deferred exchange rules turn on one question: did you get the money before you got the new property? Reg. section 1.1031(k)-1(f)(1) answers it bluntly. If you 'actually or constructively' receive money 'in the full amount of the consideration for the relinquished property' before you receive like-kind replacement property, 'the transaction will constitute a sale and not a deferred exchange'.
The regulation defines both kinds of receipt in paragraph (f)(2). Actual receipt happens when you receive the money or its economic benefit. Constructive receipt happens when it is 'credited to the taxpayer's account, set apart for the taxpayer, or otherwise made available' so you could draw on it. A wire that posts to your checking account meets both tests on the day it lands.
Your intermediary's protection does not help here. The qualified intermediary safe harbor in paragraph (g)(4) only keeps money the intermediary holds from counting as yours. Money that never reached the intermediary is outside it.
Sending the money back fast is not a recognized cure, and the case law points the other way
Sellers who catch the error within hours usually ask whether a same-day return counts. We found no regulation, revenue procedure or published ruling that treats a returned wire as never received, and paragraph (f)(2) ties receipt to the moment the funds are credited, not to how long you keep them.
The closest appellate authority is Carlton v. United States, decided by the Fifth Circuit in 1967. The Carltons planned an exchange, but at closing they took the buyer's check, deposited it and used it the same day to buy the replacement land. The court held it was a sale because 'the mark of a sale is the receipt of cash for the property'.
That does not mean nothing can be argued. Facts such as funds frozen by your bank before you could use them, or a closing agent's written admission of error, are worth documenting for your CPA or tax attorney. Treat any argument as a litigation position, not a plan.
Worked example: a full misdirected wire costs about $152,800 federal; a partial one costs far less
Hypothetical, round numbers, state tax and selling costs ignored; run your own numbers with your CPA. You sell a rental for $1,000,000 with no mortgage and an adjusted basis of $400,000 after $200,000 of depreciation. Realized gain is $600,000. The closing agent wires all $1,000,000 to your bank.
Under paragraph (f)(1) the whole $600,000 is recognized. The $200,000 depreciation layer is unrecaptured section 1250 gain taxed at up to 25%, or $50,000, per IRS Topic 409. If the remaining $400,000 sits in the 20% bracket, that adds $80,000, and the 3.8% net investment income tax on $600,000 adds $22,800. Total: about $152,800 federal.
Now suppose the agent sent $950,000 to the intermediary and only a $50,000 balance to you. Paragraph (g)(4)(vii) lets you receive money directly from a party other than the intermediary without losing the safe harbor for the rest. The $50,000 is boot, taxed first as depreciation recapture, about $14,400 at 25% plus 3.8%, and the $950,000 can still buy replacement property.
What to do in the first 48 hours
Do not spend the money, and do not move it yourself to the intermediary as if nothing happened. Call your CPA or tax attorney and your intermediary the same day, and get a written timeline from the closing agent showing when the wire was sent and to which account.
Find out exactly what reached you. A full misdirection and a partial one are different outcomes, and the settlement statement is the evidence. If the closing agent still holds part of the funds, that part should go to the intermediary under the existing exchange agreement, and your adviser should confirm the account was never yours to draw on. The rules on escrow money are covered in can the buyer wire proceeds to the title company.
If the wire was diverted by a fraudster rather than misdirected to you, the steps are different. The Consumer Financial Protection Bureau tells victims to contact their bank immediately, ask for a wire recall and file a complaint at the FBI's Internet Crime Complaint Center.
When the exchange is gone, the gain can still be deferred another way
A failed exchange still leaves options. Section 1400Z-2 lets you defer capital gain you invest in a qualified opportunity fund within the 180-day period beginning on the date of the sale. Ordinary depreciation recapture does not qualify, and the trade-offs are set out in moving 1031 funds into an opportunity zone fund and on our opportunity zone page.
A Delaware Statutory Trust can still be bought with the cash, but without an exchange it buys no deferral; buying a DST without a 1031 explains what that purchase does and does not do. The full menu, including installment and charitable routes, is in options after a failed 1031 exchange.
Prevention is cheap by comparison. Before closing, confirm that the closing instructions and the settlement statement name the intermediary as payee of the net proceeds, and that every wire instruction is confirmed by phone at a number you already have. The checklist is in protecting a 1031 from fraud and errors.
Related questions
The money sat in my account for only two hours. Does that matter?
Not under any published rule. Reg. section 1.1031(k)-1(f)(2) fixes receipt at the time funds are credited to your account, and no regulation measures how long you hold them.
Can the title company's error insurance pay my tax?
Possibly, as a claim against the closing agent, but that is a contract and insurance question, not a tax one. The tax result follows the receipt; ask your attorney whether the closing instructions make the agent liable.
Does the qualified intermediary bankruptcy safe harbor help me?
No. Rev. Proc. 2010-14 covers exchanges that fail solely because of an intermediary's default, and only for taxpayers who did not receive the proceeds before the default.
What if only my security deposits and prorated rents were paid to me?
Those items are disregarded under Reg. section 1.1031(k)-1(g)(7) when they appear under local custom on the closing statement. Receiving them does not break the safe harbor.
Can I start a new exchange with the money?
No. An exchange needs relinquished property transferred through an intermediary; once the sale is complete with cash in hand, there is nothing left to exchange. See is it too late to start a 1031 exchange.
