Cross-Border Real Estate Closings: FIRPTA Withholding Guide 2026

Cross-border real estate closings turn on one federal rule more than any other: when a foreign person sells U.S. real property, the buyer must withhold 15% of the gross price and send it to the IRS by the 20th day after the transfer, unless an exception applies. The exceptions are narrow: a signed non-foreign certification, a $300,000 residence exemption, a 10% residence rate up to $1,000,000, or an IRS withholding certificate. The transaction coordinator’s job is to ask the right question before the contract is signed.

One condo, one seller, four different withholding bills

Start with numbers instead of definitions, because cross-border real estate closings are easiest to understand through one file. Marie lives in Ontario and owns a condo in Scottsdale that she bought for $410,000. Cross-border real estate closings like hers look identical on the purchase agreement. They are not identical at the settlement table, because the withholding changes with the price and with what the buyer plans to do with the property.

The base is the amount realized, which is the gross price, not Marie’s profit. On the $640,000 sale her gain is roughly $230,000, yet $96,000 or $64,000 leaves the closing table before she sees a dollar. That gap is why cross-border real estate closings generate so many last-minute calls, and why the intake questions below belong at contract, not at closing.

Question 1: is any seller a foreign person?

In cross-border real estate closings, withholding is the default. The buyer, called the transferee in the statute, is the withholding agent and is liable for the tax if it does not withhold. The way out is a certification. Under Treasury Regulation 1.1445-2(b)(2), the seller signs a statement under penalties of perjury that she is not a foreign person, with her name, identifying number, and home address. A valid Form W-9 also works, and the buyer keeps the certification through the fifth taxable year after the transfer.

For a TC, this is a document-collection task with a deadline, and it is the first control in cross-border real estate closings. Ask for the certification when the contract is accepted, not in the closing packet. A Canadian resident cannot sign it truthfully, and that refusal is the signal that the rest of this checklist applies. If you manage seller documents across a brokerage, the same record belongs in the retention schedule described in our state-by-state records retention guide.

Question 2: which price band applies?

Three numbers matter in cross-border real estate closings, and each comes from a different part of the statute. The general 15% rate is in section 1445(a). The zero-withholding case for an amount realized of $300,000 or less is in section 1445(b)(5). The reduced 10% rate for an amount realized of $1,000,000 or less is in section 1445(c)(4). The IRS FIRPTA page states the 15% rule and the $300,000 residence exception.

Here is the trap in the way this rule gets repeated. Plenty of summaries say “10% between $300,000 and $1 million” and stop. The 10% rate, like the zero case, applies only when the property is acquired for use as a residence. Drop that condition and a TC will quote the lower number to a buyer who is purchasing a rental. The rate belongs to the buyer’s plan, not to the price alone.

Question 3: who is the buyer on paper?

The $300,000 exemption has a buyer test, and it is where cross-border real estate closings most often go sideways. Under 1.1445-2(d)(1), one or more individuals must acquire the property, and each must have definite plans to live there for at least 50 percent of the days the property is used in each of the first two 12-month periods. Days a family member lives there count, and vacant days do not. A company buyer cannot use it. If several sellers split a sale above $300,000, the exemption stays unavailable even when each share is under the line, as the IRS page explains.

If the buyer says it will live there but then does not, the buyer is the one who owes the tax unless something unforeseeable changed the plan. That is why a careful settlement agent asks for a short written statement of intent even though the regulation says nothing has to be filed with the IRS. For the 10% band, how an entity buyer is treated is a question for the settlement agent or tax counsel, because I did not find it stated on a primary page this run.

The 20-day clock, and what moves it

Timing is where cross-border real estate closings fail most often. Per the Instructions for Form 8288, the buyer files Form 8288 and pays the withheld tax by the 20th day after the transfer date, and the transfer date is the first date the buyer pays consideration or assumes a liability. Not the recording date, and not the date the check clears.

Two details save headaches in cross-border real estate closings. First, if the seller has no taxpayer identification number yet, the buyer still files Forms 8288 and 8288-A on time, but the IRS will not stamp the seller’s copy until the number arrives, and the seller generally needs that stamped copy to claim credit on her U.S. return. The IRS says a seller can request an ITIN, using Form W-7, once there is a binding sales contract, so the application can start before closing. Second, the same instructions warn that a pending certificate request made mainly to delay payment still accrues interest and penalties from day 21. The Form 8288 page lists the related forms. Late filing and late payment carry section 6651 penalties, and a willful failure can bring a penalty of up to $10,000 under section 7202.

What changed on the entity side: the FinCEN reporting rule

A second federal rule used to sit beside FIRPTA on some of these cross-border real estate closings. FinCEN’s residential real estate reporting rule had a compliance date of March 1, 2026 after a postponement announced September 30, 2025. FinCEN’s own rule newsroom now says a federal court in the Eastern District of Texas vacated the rule on March 19, 2026, that the order is in force, that the government has appealed, and that reporting persons are not required to file Real Estate Reports and carry no liability for not filing.

That status can change on appeal, so the practical move is small: ask the title company at file open whether it expects any federal report on the transaction, and write the answer in the file with a date. Wire instructions deserve the same discipline, and our wire fraud verification guide covers the call-back steps. A holdback that arrives by wire from a foreign account gets verified like any other.

A TC checklist for cross-border real estate closings

This is the three-question intake I would run on every file where a seller has an out-of-country address, a foreign phone number, or a foreign tax residence. It takes ten minutes at contract and removes most of the closing-week surprises in cross-border real estate closings.

• At contract, ask the seller for the non-foreign certification or a W-9. If she cannot sign it, flag the file as foreign-seller and tell the settlement agent the same day.
• Record the price band and the buyer’s stated plan to occupy, and note whether the buyer is an individual or a company.
• Decide with the seller and her tax adviser whether to file Form 8288-B early, because the IRS normally acts on a certificate request within about 90 days and a closing date may not wait that long.
• Calendar the 20th day after the funding date and assign it to a named person, not to the closing date.
• Start the ITIN conversation (Form W-7) once the contract is binding if the seller has no U.S. number.
• Store the certification, the Form 8288 confirmation, and the stamped copy in the transaction record, the same way for every one of your cross-border real estate closings.

Each item is a dated task with an owner, which is the kind of work ReBillion handles as an AI control plane that orchestrates your stack: it coordinates your TMS, CRM, signature, and comms, so the 20-day clock sits next to the closing date instead of in someone’s memory.

Frequently asked questions

What are cross-border real estate closings?

Cross-border real estate closings are U.S. property sales or purchases where a party is outside the country, most often a foreign seller. The main federal consequence is FIRPTA: the buyer must withhold a percentage of the amount realized and send it to the IRS, unless the seller proves non-foreign status or a stated exception applies.

Does a Canadian buyer trigger FIRPTA withholding?

No. In cross-border real estate closings, FIRPTA withholding is triggered when a foreign person disposes of U.S. real property, so the obligation falls on the buyer when the seller is foreign. A Canadian buyer becomes the FIRPTA seller later, when that buyer resells the property.

What is the FIRPTA withholding rate in 2026?

For cross-border real estate closings, the general rate is 15 percent of the amount realized under section 1445(a). It drops to 10 percent when the amount realized is $1,000,000 or less and the buyer acquires the property for use as a residence, and to zero when the amount realized is $300,000 or less and an individual buyer meets the residence test.

When is the FIRPTA payment due?

In cross-border real estate closings, Form 8288 and the withheld tax are due by the 20th day after the transfer date, which is the first date the buyer pays consideration or assumes a liability. If a withholding certificate application is pending, the buyer still withholds at transfer, but the filing deadline moves to the 20th day after the IRS mails the certificate or a denial.

Does a signed W-9 end FIRPTA withholding?

A valid Form W-9 from the seller is one accepted way to give the non-foreign certification under Treasury Regulation 1.1445-2(b)(2). The buyer must keep it through the fifth taxable year after the transfer, and a certification the buyer has reason to doubt does not protect the buyer.

Sources, and what I left out

Every rate, threshold, and deadline above about cross-border real estate closings was read on the primary page this run: the statute text of 26 U.S.C. 1445, the Treasury regulation, the IRS FIRPTA withholding page, the Form 8288 instructions, and the FinCEN newsroom. I left out three things I could not bind to a primary source: the common “10% from $300,000 to $1 million” line without its residence condition, any state-level withholding amounts, and Canadian-side tax treatment.
