Form 8288-B: Reducing FIRPTA Withholding Before Closing
If 15 percent of the gross sale price of a U.S. property is about to be withheld at closing and the actual tax liability on the sale is a fraction of that figure, there is a formal mechanism to ask the IRS to reduce the withholding before the money ever leaves the closing table. It is an application for a withholding certificate, made on Form 8288-B, and understood correctly it is the difference between waiting many months for a refund and never overpaying in the first place.
The withholding rule the application responds to
IRC §1445(a) requires the transferee, generally the buyer, in a disposition of a U.S. real property interest by a foreign person to withhold and remit to the IRS 15 percent of the amount realized on the transaction. That 15 percent rate, raised from the previous 10 percent by the Protecting Americans from Tax Hikes Act of 2015 for dispositions after February 16, 2016, is calculated on the gross sale price, not on the gain. A reduced 10 percent rate applies under IRC §1445(c)(4) where the amount realized is more than $300,000 but does not exceed $1,000,000 and the property is acquired for use as a residence, and a full exemption from withholding applies under §1445(b)(5) where the amount realized does not exceed $300,000 and the same residence-use condition is met. Above $1,000,000, or where the residence-use condition is not met, the standard 15 percent rate applies regardless of what the actual gain turns out to be.
The withholding is reported and paid over using Form 8288, U.S. Withholding Tax Return for Dispositions by Foreign Persons of U.S. Real Property Interests, and the accompanying Form 8288-A statement, which are ordinarily due within 20 days after the date of transfer. Form 8288-B, Application for Withholding Certificate for Dispositions by Foreign Persons of U.S. Real Property Interests, is the separate application that asks the IRS to authorize a reduced amount, and its mechanics are set out in Treas. Reg. §1.1445-3.
What the application actually asks the IRS to do
Under Treas. Reg. §1.1445-3(c), the IRS may issue a withholding certificate on several grounds, the most commonly used of which is that the amount otherwise required to be withheld exceeds the transferor's maximum tax liability on the disposition. The application presents the numbers behind that comparison directly: the amount realized, the adjusted basis, documented improvements, selling expenses, any depreciation subject to recapture, and the resulting computation of expected gain and expected tax, which the IRS then compares against the 15 percent standard withholding figure.
If a certificate is issued, it specifies the reduced amount, which can be a smaller percentage, a fixed dollar figure, or in some cases zero, and the closing agent withholds and remits only that amount rather than the standard 15 percent. The practical effect is that the cash stays available to the seller at closing instead of sitting with the IRS for the months it typically takes to receive it back as a refund after filing the year's return.
When applying is worth the effort
The larger the gap between the gross sale price and the actual expected gain, the stronger the case for applying. Four fact patterns produce the widest gaps.
- A sale at a loss or near break-even. Withholding under §1445 is calculated on the gross price; the tax is calculated on the gain. Where there is little or no gain, the mismatch between the two figures is close to total.
- A modest gain on an expensive property. A $50,000 gain on a $900,000 sale still attracts $135,000 of standard withholding at the 15 percent rate, an amount that has no relationship to the actual tax owed on that gain.
- A property with a high adjusted basis after substantial documented capital improvements over a long holding period, which narrows the taxable gain relative to the gross sale price.
- A mortgage payoff consuming most of the sale proceeds, where the amount required to be withheld under the standard rate can exceed the actual cash the seller receives after the loan is paid off, occasionally making the sale impossible to close at all without a reduced certificate.
Worked example
A non-resident individual purchased a Florida condominium in 2015 for $420,000 and sells it in 2026 for $650,000, having spent $60,000 on documented capital improvements and $35,000 on selling costs including commission. The adjusted basis is $480,000. The expected gain is roughly $135,000, before accounting for any depreciation recapture, since the property was never rented. Standard withholding under §1445(a) on the $650,000 amount realized, at 15 percent, would be $97,500. The maximum federal tax on a $135,000 long-term capital gain, even at the highest applicable rate, comes to well under that figure. That gap between $97,500 of standard withholding and the actual expected tax liability is exactly the kind of mismatch a Form 8288-B application is built to correct, and in this fact pattern the IRS-issued certificate would be expected to authorize withholding closer to the actual computed liability rather than the full statutory amount.
| Figure | Amount |
|---|---|
| Sale price (amount realized) | $650,000 |
| Original purchase price | $420,000 |
| Documented improvements | $60,000 |
| Adjusted basis | $480,000 |
| Selling costs | $35,000 |
| Expected gain | approximately $135,000 |
| Standard withholding at 15% | $97,500 |
The filing deadline that decides everything
The application must be filed no later than the date of the transfer, meaning the closing date, under Treas. Reg. §1.1445-3(b). An application filed after closing does not reduce withholding on a transfer that has already occurred; at that point the standard amount has already been withheld under the general rule, and recovering an overwithheld amount means waiting for a refund on the year's income tax return rather than adjusting the withholding itself.
The IRS has stated that it will generally act on a complete application within 90 days of receipt, but that 90-day window is a processing target, not a guarantee, and it runs from a complete submission rather than from a first draft. Applying on the closing date itself is therefore not a workable plan. The application should realistically be prepared and submitted well before closing, which means the decision to pursue a certificate has to be made early in the transaction, ideally when the property goes under contract, rather than when the closing documents are already being assembled.
What happens to the withholding while the application is pending
Where a complete application is filed with the IRS on or before the date of transfer and remains pending at closing, Treas. Reg. §1.1445-1(c)(2) allows the transferee's obligation to report and pay over the amount otherwise required to be withheld to be suspended until shortly after the IRS responds to the application. Specifically, the amount need not be reported on Form 8288 and paid over until the 20th day after the date the IRS mails its determination, whether that determination is an approval at a reduced rate, a denial, or something in between. In practice this generally means the withholding agent, typically the closing attorney or title company, holds the funds in an escrow or similar arrangement rather than immediately remitting the full standard amount to the IRS at closing, and then remits whatever amount the IRS's eventual determination requires.
None of this happens automatically simply because an application exists. The buyer's side and the closing agent both need to be told, in writing, before closing that an application is pending, since a closing agent who has not been informed of a pending application has no reason to depart from remitting the standard 15 percent in the ordinary course. This is as much a coordination problem between the parties to the transaction as it is a tax filing question, and it needs to be resolved contractually, generally through the purchase agreement or closing instructions, well before the closing date rather than negotiated at the closing table itself.
What the application has to document
The application is built around the same numbers as the worked example above: the sale price, the original purchase price, documented capital improvements supported by records rather than estimates, selling costs, any depreciation previously claimed, and the resulting computation of expected gain and expected tax. Taxpayer identification numbers are required for the parties to the transaction, which raises a dependency that catches a meaningful number of sellers by surprise: a non-resident seller without an existing U.S. taxpayer identification number needs to obtain one before, or in narrow cases concurrently with, the certificate application, and obtaining that number has its own lead time. The Form W-7 instructions include a specific exception, generally referred to as the exception for withholding on the disposition of a U.S. real property interest, that permits an ITIN application to be submitted alongside the Form 8288-B application rather than requiring it to be attached to a completed tax return, which is the route most sellers without an existing ITIN end up using.
A certificate does not replace the year's tax return
A withholding certificate governs the withholding only. It does not compute or finalize the actual tax owed on the sale. A federal income tax return for the year of the disposition is still required, typically Form 1040-NR for an individual non-resident seller, reporting the sale and computing the actual liability under IRC §897 and the general capital gains provisions. The certificate reduces the amount deposited with the IRS at closing; the return, filed after the year ends, settles the account and either produces a refund of any amount overwithheld or, less commonly, an additional amount due if the actual computation differs from what the certificate assumed.
Where the property has been rented
Depreciation claimed during a rental period is recaptured on sale. Unrecaptured §1250 gain attributable to straight-line depreciation on real property is taxed at a maximum federal rate of 25 percent under IRC §1(h)(1)(E), which increases the expected tax figure used in the application and narrows the gap the entire application depends on. Building the application on the actual rental history matters here specifically, including whether the rental income itself was properly reported in prior years, since recapture has to be computed on the depreciation actually allowed or allowable, not simply on what was claimed. An application that understates expected gain by omitting recapture, whether deliberately or through oversight, is a weaker application than one that includes the full picture, including the less favorable figures, because the IRS's review is comparing the application's numbers against the same recapture rules regardless of what the application states.
What to do
Establish three numbers as early as possible in the transaction: the expected sale price, the documented cost basis including all capital improvements with supporting records, and any depreciation claimed if the property was ever rented. Those three figures determine whether a certificate is worth pursuing at all. Then confirm, immediately, whether every party to the transaction has a U.S. taxpayer identification number, since that single dependency has the longest lead time of anything in this entire process and is the item most likely to make an otherwise well-timed application arrive too late to matter.
