If you are buying a property from a seller who is doing a 1031 exchange, the effect on you at closing is mostly procedural: you will sign a cooperation clause in the purchase agreement, sign a Notice of Assignment at the closing table acknowledging that a Qualified Intermediary is receiving the sale funds, and accept that the seller’s closing date is not flexible. Your costs, your title, and your tax basis are unchanged. The one place a 1031 exchange can create real financial exposure for you is when the seller is a foreign person, because FIRPTA withholding is the buyer’s legal responsibility.
What the Seller Is Actually Doing
Section 1031 of the Internal Revenue Code lets an investor who sells real property held for business or investment use defer the capital gains tax by reinvesting the proceeds into like-kind property also held for business or investment.1Office of the Law Revision Counsel. 26 USC 1031 Exchange of Real Property Held for Productive Use or Investment Personal residences do not qualify.2Internal Revenue Service. Like-Kind Exchanges Under IRC Section 1031 The deferral belongs to the seller. You can be on either side of the deal, buying the seller’s relinquished property or selling your property to an investor as their replacement, and the tax benefit still sits entirely with them.
The Cooperation Clause in the Purchase Agreement
The first sign you are part of a 1031 exchange is a paragraph in the purchase and sale agreement called a cooperation clause. The seller states that they intend to structure the sale as a tax-deferred exchange and asks you to cooperate with the procedural steps that requires. By signing, you agree to execute the extra paperwork needed to keep the exchange valid.
Read the clause before signing. It should say plainly that your cooperation will not create additional costs or legal liability for you, and that any exchange-related expenses belong to the seller. Most standard contract forms include a pre-written version that meets IRS expectations while keeping your obligations minimal. If the language in front of you doesn’t include those protections, ask for them.
The Qualified Intermediary and the Notice of Assignment
Federal tax rules require that the seller never have actual or constructive control over the sale proceeds. To accomplish this, the seller hires a neutral third party called a Qualified Intermediary (QI) to hold the funds and manage the exchange paperwork. The seller assigns their rights under your purchase contract to the QI, and a Treasury safe harbor keeps the QI from being treated as the seller’s agent for tax purposes.3eCFR. 26 CFR 1.1031(b)-2 Safe Harbor for Qualified Intermediaries
What this looks like from your side of the table: the QI’s name will appear on documents alongside or instead of the seller’s. Your rights under the original contract are unchanged. The QI does not take title. Ownership transfers directly from the seller to you through a process called direct deeding, so the chain of title stays clean. The QI only handles the money.
At closing, you will sign one additional document, a Notice of Assignment, confirming that you are aware the seller’s contractual rights have been transferred to the QI and that the QI will receive your purchase funds. It takes about a minute to sign. Before you do, check that the parties named on the notice match the entities discussed throughout the transaction.
Your Costs, Title, and Tax Basis Do Not Change
A 1031 exchange does not add to the buyer’s closing costs. Title insurance premiums, escrow fees, recording charges, and transfer taxes stay exactly what they would be in a conventional sale, allocated between you and the seller under whatever you negotiated in the purchase agreement.
The QI’s fee, typically $500 to $2,000 depending on complexity, is the seller’s expense and should not appear on your side of the closing statement. If you see an unfamiliar administrative charge on your settlement sheet, ask the closing agent to confirm it is billed to the seller. This is where most confusion crops up, and it is almost always a clerical mistake rather than an attempt to shift costs.
Your cost basis in the property is what you paid for it. The seller’s carryover basis and deferred gain travel with the seller into their replacement property, not with the property you just bought. You depreciate, improve, and eventually sell the property based on your own purchase price, with no connection to the seller’s exchange history.
Timing Pressure at Closing
The seller is running against two firm deadlines that cannot be extended for any reason. From the date they close on their relinquished property, they have 45 days to identify a replacement property and 180 days to complete the entire exchange.1Office of the Law Revision Counsel. 26 USC 1031 Exchange of Real Property Held for Productive Use or Investment Missing either deadline kills the deferral.
If you are buying the seller’s relinquished property, the seller wants to close promptly so their identification window can start. Delays on your end will create friction. If you are selling a replacement property to an exchanger, expect the buyer to refuse any request to push the closing date. A delay that looks minor to you could cost them tens of thousands in capital gains tax, and asking for an extension may draw a demand for concessions or a threat to walk. Practical response: get financing and inspections done early, and treat the closing date as immovable.
FIRPTA Withholding When the Seller Is a Foreign Person
This is the one place a 1031 transaction can create a real financial obligation for you. Under the Foreign Investment in Real Property Tax Act (FIRPTA), when a foreign person sells U.S. real property, the buyer is legally required to withhold 15 percent of the total sales price and remit it to the IRS. If the property will be your residence and the price is $1,000,000 or less, the rate drops to 10 percent.4Office of the Law Revision Counsel. 26 USC 1445 Withholding of Tax on Dispositions of United States Real Property Interests If you are buying a home for personal use at $300,000 or less and plan to live in it at least half the time for the first two years, withholding is waived.5Internal Revenue Service. Exceptions From FIRPTA Withholding
The 1031 wrinkle: even though the seller is deferring their gain, FIRPTA withholding still applies unless the seller obtains a withholding certificate from the IRS. A qualifying 1031 exchange is one of the grounds on which the IRS will issue a certificate reducing or eliminating the withholding.6Internal Revenue Service. Form 8288-B Application for Withholding Certificate for Dispositions by Foreign Persons of U.S. Real Property Interests The seller has to apply for that certificate and receive it. If they have applied but the IRS has not yet responded by the closing date, you are not required to send the withholding to the IRS until 20 days after the IRS mails the certificate or a denial.
Failure to withhold when required does not stay with the seller. The statute makes the buyer personally liable for the withholding amount plus interest. When you learn the seller is a foreign person, confirm with the closing agent that FIRPTA is being handled correctly and ask specifically whether a withholding certificate has been applied for. Do not rely on the seller’s assurance alone.
If the Exchange Falls Through
Once your purchase closes and the deed is recorded in your name, the seller’s exchange is no longer your concern. If the seller misses the 45-day identification window or the 180-day closing window, their deferral is lost and they owe capital gains tax on the sale. Your ownership, your title, and your purchase price are all final. A failed exchange does not unwind your transaction or create any tax consequence for you.
The one indirect scenario: if you are selling a replacement property to an exchanger and their QI releases funds late or the exchanger backs out before closing, your standard contract remedies still apply. Earnest money, specific performance rights, and any other protections written into your purchase agreement are unaffected by the 1031 structure sitting on the other side of the deal.
