What Is FIRPTA? A Guide for Foreign Property Sellers
FIRPTA is the U.S. withholding system that applies when a foreign person sells U.S. real estate — but the amount withheld at closing is a tax payment, not necessarily your final tax bill, and in some cases it can be reduced before closing ever happens.
The standard FIRPTA withholding rate is 15% of the amount realized on the sale. That withholding isn't a final determination of what you owe — it's a payment toward it. If too much was withheld, you generally recover the difference by filing a U.S. tax return. And in some situations, you can avoid overpaying at closing in the first place by applying for a reduced withholding amount before the sale closes.
Can FIRPTA Withholding Be Reduced Before Closing?
Sometimes.
The IRS can authorize withholding at a different amount when the standard 15% would be greater than the seller's expected maximum U.S. tax liability. A foreign seller requests this determination by applying for a FIRPTA withholding certificate, commonly using Form 8288-B. If the IRS approves the application, it issues a certificate telling the parties how much should actually be withheld from the sale.
This can be particularly valuable when the seller is selling at a loss, has only a small taxable gain, has substantial tax basis in the property, has significant allowable selling costs, or would otherwise have much more withheld than the expected final U.S. tax.
Example: Suppose the sales price is $1,000,000. Normal FIRPTA withholding would be $150,000. But after reviewing the property's tax basis, improvements, depreciation, and expected selling expenses, the seller's expected maximum U.S. tax is only $45,000. A withholding-certificate application may allow the IRS to authorize withholding closer to that $45,000 figure, rather than requiring the full $150,000 to be tied up until the return is filed.
The IRS states that it will act on a complete withholding-certificate application within approximately 90 days after receiving all the information necessary to make its determination. In practice, that's the official target, not a guarantee — real-world processing has been running longer than 90 days at times, and delays beyond the stated timeline are commonly reported. Because of both the official timeline and the real possibility of running longer, this needs to be considered well before closing, with real buffer built in — not the week before.
One case worth knowing about: an attorney colleague once described a withholding certificate application that took almost a year to resolve — by the time it came back, the certificate no longer served any real purpose for the client. In that situation, the more practical path turned out to be skipping the certificate entirely and simply letting the standard 15% withholding happen at closing, then recovering the excess through the tax return process instead. That's not a failure of planning — sometimes it's the more realistic choice from the beginning, especially when a closing needs to happen on a fixed schedule and the certificate timeline is too uncertain to count on.
Why FIRPTA-Related ITIN Applications Get Priority
Here's something worth understanding about the timing pressure built into this whole process: a foreign seller generally can't apply for an ITIN under the FIRPTA exception until there's a legally binding contract to sell the property. You can't get ahead of this by applying early "just in case" — the IRS won't issue an ITIN for this reason before that contract exists.
That creates a real problem, because real estate closings have fixed dates that don't bend for IRS processing schedules the way a routine tax return might. In practice, ITIN Operations prioritizes FIRPTA-related ITIN applications ahead of other application types — this isn't something you'll necessarily find spelled out as a specific guaranteed timeframe, but it reflects how these applications actually get handled given the hard deadline every closing creates. The application literally can't exist before the contract does, so the system has to move faster once it does.
Not every seller applies for a withholding certificate in advance — and as the case above shows, sometimes that's the right call, not just a missed opportunity. Even when the underlying math clearly favors a refund, waiting to recover the excess afterward instead has real timing consequences of its own, and it's worth understanding those before deciding which path fits your situation. We cover exactly what that recovery process looks like — including how long it can realistically take — in "I Sold U.S. Real Estate. How Do I Recover Excess FIRPTA Withholding?"
What Are Forms 8288 and 8288-A?
These are different from the seller's application for a withholding certificate.
When FIRPTA tax is actually withheld, the buyer or other withholding agent reports and sends the withholding to the IRS. The IRS then provides the foreign seller with a stamped copy of Form 8288-A showing the withholding credited to that seller.
Keep this document. The seller generally uses it when filing the U.S. income-tax return to claim credit for the FIRPTA tax that was already withheld.
This matters because FIRPTA withholding is only a tax payment — the seller's U.S. tax return determines the actual tax owed. If $100,000 was withheld but the final U.S. tax is only $30,000, the seller generally claims the full $100,000 withholding on the return and requests the excess $70,000 back as a refund.
Are There Exceptions or Reduced Rates to the 15% FIRPTA Withholding?
Yes, but they come from several different rules.
Buyer Will Use the Property as a Residence
If an individual buyer purchases the property to use as a residence and the total amount realized is $300,000 or less, FIRPTA withholding may not be required at all — provided the buyer (or a family member) has definite plans to live at the property for at least 50% of the days it's used during each of the first two 12-month periods after the transfer.
For qualifying residence purchases above $300,000 but not more than $1 million, the withholding rate may be reduced to 10% rather than 15%.
One trap worth knowing about: if the property has multiple foreign co-owners, the $300,000 threshold is based on the total amount realized on the sale, not each owner's individual share. Three foreign co-owners splitting a $600,000 sale don't qualify for the exemption just because each person's allocated share is under $300,000 — the full sale price is what counts.
IRS Withholding Certificate
As covered above, the IRS can also authorize reduced or zero withholding through a withholding certificate when the facts support a lower amount — for example, when the standard withholding would be substantially greater than the seller's expected maximum tax liability.
Tax Treaty or Other Nonrecognition Provision
In some situations, a provision of the Internal Revenue Code or an applicable U.S. tax treaty may provide that gain from the transaction isn't recognized. When the applicable requirements are satisfied, FIRPTA withholding may not be required — although specific notice requirements apply.
Tax treaties need to be reviewed individually. A treaty doesn't automatically reduce the standard FIRPTA rate simply because the seller is a resident of a treaty country — most U.S. income-tax treaties actually preserve the United States' right to tax gains from U.S. real estate. The actual treaty provision and transaction need to be reviewed before claiming a reduced rate or exemption.
A Related Point: The Principal Residence Exclusion
Separately from FIRPTA-specific exceptions, the general exclusion of gain from the sale of a personal residence can apply to nonresident aliens selling their own U.S. home, up to a limit per person. This is a different rule from the FIRPTA withholding exceptions above, but it can factor into the expected-tax calculation used to support a withholding certificate application — another reason this is worth reviewing with someone familiar with both sides of the analysis before closing.
Getting This Right Requires the Right Preparer
This is exactly the kind of situation where the preparer's actual experience matters more than their price. Calculating an accurate expected-tax figure for a withholding certificate, correctly applying the residence exceptions, and properly claiming withholding credit on the return all require someone who regularly works with FIRPTA — not every preparer who says they "do taxes" has that experience, and a mistake here can mean tens of thousands of dollars tied up longer than necessary or a certificate application that gets denied. See "Why Hire a Credentialed Tax Preparer?" for what to look for before you hire someone.
How ITIN Abroad Can Help
ITIN Abroad works with foreign sellers navigating FIRPTA. Depending on your situation, we can help you determine whether a withholding-certificate application makes sense before closing, prepare and submit Form 8288-B, prepare your ITIN application alongside the FIRPTA filing, prepare the U.S. tax return needed to claim credit for withholding, and help you understand realistic timelines so you know what to expect and when.
The goal isn't just to survive the FIRPTA process — it's to make sure you don't leave money tied up with the IRS longer than necessary, either before closing or after.
FAQ
Is FIRPTA withholding my final tax bill?
No. It's a tax payment, not a final determination. Your actual U.S. tax return determines what you actually owe, and any excess withholding is generally refundable.
How can I reduce FIRPTA withholding before closing?
By applying for a withholding certificate using Form 8288-B, if your expected maximum U.S. tax is less than the standard withholding amount would be. The IRS's official target is about 90 days, but real-world processing has often run longer than that in practice — build in real buffer time before your closing date rather than counting on the stated timeline.
Is a withholding certificate always the right move?
Not necessarily. If the certificate timeline is too uncertain relative to your closing date, letting the standard withholding happen and recovering the excess through your tax return afterward can be the more realistic path — especially for a fixed closing date that can't wait on an unpredictable IRS timeline.
Can I apply for my ITIN early to save time before the closing?
No. You generally can't apply under the FIRPTA exception until a legally binding contract to sell exists — the IRS won't issue one for this reason beforehand. This is exactly why FIRPTA-related ITIN applications tend to get handled with priority once they're submitted: the contract requirement means there's no way to get ahead of the clock any other way.
What if I don't apply for a withholding certificate?
You can still recover excess withholding after the fact by filing a U.S. tax return and claiming credit using your Form 8288-A. The tradeoff is timing — you generally can't file until after the sale's tax year ends, plus additional processing time for the refund itself. See "I Sold U.S. Real Estate. How Do I Recover Excess FIRPTA Withholding?" for what that timeline actually looks like in practice.
Is there really no withholding if I sell for $300,000 or less?
Only if the buyer is an individual planning to use the property as their residence and meets the specific occupancy requirements. This exception doesn't apply automatically just because the price is under $300,000.
What if I own the property with other foreign sellers?
The $300,000 residence exemption is based on the total amount realized on the sale, not each seller's individual share. Multiple owners splitting a larger sale generally don't qualify just because each person's portion is small.
Does my tax treaty automatically reduce my FIRPTA withholding?
Not automatically. Most U.S. tax treaties preserve the United States' right to tax gains from real estate, so the specific treaty and transaction need to be reviewed rather than assumed.
Should I hire someone experienced with FIRPTA specifically?
Yes. This is a specialized area, and a preparer without regular FIRPTA experience can miscalculate the expected tax, mishandle the withholding certificate application, or make errors that delay your refund considerably.
FIRPTA withholding feels final at closing, but it usually isn't. Whether you reduce it in advance with a withholding certificate or recover the excess afterward through your tax return, the money withheld beyond your actual tax liability is generally yours to get back.
Understanding which path fits your sale — and starting early enough for either one to actually work — is the real goal.
