Form 8288-B: How Foreign Sellers Reduce FIRPTA Withholding on U.S. Real Estate
When a foreign person sells U.S. real property, the buyer is generally required to withhold 15% of the gross sale price and send it to the IRS. That figure is based on the sale price, not the actual gain, which means a seller with a modest profit, or even a loss, can watch a large sum sit in escrow for months while waiting on a refund. Form 8288-B exists to fix that mismatch before it happens.
This guide covers what Form 8288-B does, who needs to file it, when it makes sense, what documentation the IRS expects, how to actually file it, how the timeline works, common mistakes, how state withholding stacks on top of the federal rule, and answers to frequently asked questions.
What Form 8288-B Actually Does
Form 8288-B is the Application for Withholding Certificate for Dispositions by Foreign Persons of U.S. Real Property Interests, filed under IRC §1445. It asks the IRS to approve a lower withholding amount, or in some cases zero, that better matches the seller's expected U.S. tax liability rather than the flat 15% default that applies to the full amount realized on the sale.
Without an approved certificate, the buyer (the withholding agent) must follow the default rule and remit 15% of the gross sale price to the IRS within 20 days of closing. The IRS generally acts within about 90 days of receiving a substantially complete application, though actual processing times can run longer depending on IRS staffing and workload. Check the current instructions to Form 8288-B or the IRS website for up-to-date processing estimates rather than relying on a fixed number.
It's worth being clear about what the certificate does not do. It does not eliminate the underlying tax. It only adjusts how much cash gets held back at closing versus released to the seller. The seller still owes whatever U.S. tax is actually due on the sale, and still must file a U.S. tax return (Form 1040-NR for individuals, Form 1120-F for corporations) for the year of sale.
Who Must File
The seller, called the transferor in IRS terminology, files Form 8288-B. The buyer, or transferee, is the one who actually withholds and remits funds using Form 8288 and Form 8288-A. A foreign person for these purposes includes a nonresident alien individual, a foreign corporation, a foreign partnership, a foreign trust, or a foreign estate.
A few identification points worth knowing: if the property is held through a foreign-owned single-member LLC that's disregarded for federal tax purposes, the foreign owner files in their own name and uses their own taxpayer identification number, not the LLC's. Lawful permanent residents (green card holders) are treated as U.S. persons for tax purposes, so FIRPTA withholding doesn't apply to their sales and Form 8288-B isn't the relevant form. And when a foreign partnership sells U.S. real property, gain generally needs to be allocated to each partner's individual tax situation as part of building the application; a single partnership-level number won't necessarily reflect what each partner actually owes.
When a Reduced Withholding Certificate Makes Sense
The default 15% withholding overstates the actual tax due far more often than most sellers expect. Common situations where a certificate is worth pursuing include a low overall gain or an outright loss on the sale, a large adjusted basis built up through capital improvements over years of ownership, an installment sale structure where the full 15% would otherwise be withheld against the entire contract price rather than against payments as they're received, certain nonrecognition transactions such as a qualifying like-kind exchange under IRC §1031, and entity distributions where the calculated tax comes in below the default withholding amount.
In each case, the logic is the same. If a credible, well-documented calculation shows the seller's actual expected U.S. tax is lower than 15% of the amount realized, the IRS has a basis to approve a reduced figure.
Separately, two statutory exemptions apply automatically without a certificate application, when the buyer intends to use the property as a personal residence. If the sale price is $300,000 or less, withholding can be reduced to zero. If the sale price is between $300,001 and $1,000,000, the rate drops to 10% instead of 15%, when the buyer signs the appropriate residence affidavit. A buyer who signs that affidavit but doesn't actually reside in the property can be personally liable for the withholding that should have been collected, so this exemption should only be used when it genuinely applies.
What the Application Package Needs to Include
A strong Form 8288-B package is built to survive a cold review by someone who has never seen the transaction before. At minimum, it should include a signed, complete Form 8288-B, the fully executed purchase agreement and any amendments, a description of the property and the specific interest being transferred that matches the legal description on the deed (not just a mailing address or unit number), and names, addresses, and taxpayer identification numbers for every party involved.
If a seller doesn't yet have a U.S. taxpayer identification number, a completed Form W-7 should be attached so the IRS can assign an ITIN during processing, though that combined packet is mailed to the address listed in the Form W-7 instructions rather than to the FIRPTA unit. Missing a TIN, or a properly attached W-7 in its place, is treated as an incomplete application, and ITIN processing itself can add several weeks to the timeline, so starting early matters.
Beyond identifying information, the package needs a detailed tax computation showing adjusted basis, capital improvements, any depreciation taken or allowable, selling costs, and the resulting estimated tax, along with a draft closing statement that reconciles to those numbers. If a representative is signing or communicating with the IRS on the seller's behalf, a properly completed Form 2848 (Power of Attorney) should be included; other authorization formats aren't accepted. Any additional support, such as depreciation schedules, prior tax returns, or documentation for a nonrecognition or treaty position, strengthens the case further.
It's worth noting that blanket withholding certificate requests covering multiple transactions within a twelve-month window, and payment-of-tax-with-security applications, are not filed on Form 8288-B at all. Those follow a separate letter procedure, so a seller pursuing either of those routes needs a different filing.
How and Where to File
Form 8288-B is submitted by mail or fax directly to the IRS unit that handles FIRPTA withholding certificates. It is not e-filed and, as of the most recent guidance, is not accepted by email. Historically the mailing address used has been:
Internal Revenue Service, P.O. Box 409101, Ogden, UT 84409
Confirm this address against the current Form 8288-B instructions before mailing, since IRS processing addresses do change from time to time.
A few mechanical points worth getting right. The seller, or an authorized agent under a properly completed Form 2848, must sign under penalty of perjury; an unsigned form is generally treated as not filed at all. The form's instructions include a separate Washington, D.C. address in the Privacy Act notice section, but that address is only for comments on the form's design and paperwork burden, not for actual applications, and packages sent there get rerouted, costing time. If a Form W-7 is being filed alongside the 8288-B to obtain an ITIN, that combined packet is generally mailed to the address listed in the current Form W-7 instructions, not to the Ogden FIRPTA address. If any residual withholding is still due after the certificate is applied, a copy of the 8288-B and the IRS's response is generally attached to the buyer's Form 8288 when it's filed. And the application should reach the IRS by the day of closing, so mailing or faxing it in has to happen with enough lead time that it's actually received, not just postmarked, by then.
Building a Defensible Tax Calculation
The IRS is evaluating whether the seller's expected tax genuinely falls below the default withholding, so the calculation needs to hold up to scrutiny. Start with the contract price, subtract selling costs such as commissions and transfer taxes, and determine the adjusted basis by adding capital improvements to the original purchase price and subtracting any depreciation taken (or allowable, even if never actually claimed) if the property was used as a rental. The resulting gain is then taxed at the applicable rate, considering long-term capital gains rates and unrecaptured Section 1250 gain for individuals, or the corporate rate and potential branch profits tax exposure for a foreign corporation. Nonresident aliens are generally not subject to the Net Investment Income Tax, which is a common point of confusion when estimating the total.
Consider a simple illustrative example. A nonresident sells a property for $750,000. After accounting for improvements and prior depreciation, the adjusted basis comes to $690,000, and selling costs total $45,000, leaving a gain of $15,000. Default withholding on the full sale price would be $112,500, but the estimated tax on a $15,000 gain is a small fraction of that. A well-documented application, including improvement invoices and depreciation schedules, gives the IRS a clear path to approving withholding closer to the actual expected tax rather than the full statutory amount.
Timeline and How Escrow Fits In
The application should reach the IRS by the day of closing at the latest. While it's pending, the buyer must continue holding the full 15% in escrow. Filing the application does not waive or suspend the withholding requirement. That obligation continues until 20 days after the IRS mails its decision, not until the application is submitted.
Once the IRS mails its decision, whether approval or denial, the buyer has 20 days to file Form 8288 and remit whatever amount the letter specifies, attaching a copy of the certificate if any residual withholding remains due. If approved, the excess held in escrow is released to the seller, and the buyer remits only the approved, reduced amount to the IRS. If denied, the buyer remits the full default withholding, and the seller can pursue a refund of any overpayment when filing the U.S. tax return for the year of sale.
Escrow instructions should spell this out explicitly, so no one on the closing team assumes funds can be released simply because a certificate request is pending.
Common Mistakes That Slow Down or Sink an Application
A handful of process errors account for most delays and rejections. The most common is releasing escrowed funds early: the full amount must remain held until the IRS decision arrives, and a pending application is not itself a reason to release funds. Blank or missing taxpayer identification numbers are another frequent issue, since an application missing a TIN, or a properly attached Form W-7 in its place, is treated as not substantially complete.
Address formatting causes more rejections than most filers expect. A P.O. box generally cannot be used for the transferor's or transferee's address; that option is typically reserved for where the certificate itself should be mailed. A property description that doesn't match the deed, such as a unit number without a block or lot number, commonly triggers a request for more information and can add weeks to the timeline. Filers relying on an exemption or nonrecognition claim sometimes omit a required fair market value attachment, such as a recent property tax assessment or appraisal, that the IRS often expects even when it isn't explicitly flagged on the form. Calculations built around the maximum-tax basis for approval sometimes leave out depreciation recapture entirely, which produces a tax estimate the IRS is likely to reject or recalculate upward. And claiming a treaty exemption that doesn't actually apply is a common misstep, since most U.S. tax treaties preserve U.S. taxing rights over real property gains, so a treaty rarely eliminates FIRPTA withholding on its own.
Ignoring separate state withholding requirements is another frequent oversight, since a federal certificate has no effect on those obligations at all.
State Withholding That Stacks on Top of FIRPTA
Federal law sets a floor, not a ceiling. Several states impose their own withholding on real estate sales by nonresidents, and a federal Form 8288-B certificate does nothing to reduce those separately. California's Real Estate Withholding is generally 3⅓% of the sale price unless a reduced rate is approved (Form 593). Hawaii's HARPTA withholding is generally 7.25% (Form N-288B for a reduced withholding certificate). Maryland's nonresident withholding is generally 8% for individuals and 8.25% for entities (Form MW506NRS).
Rates and forms change periodically, so confirm current requirements with the relevant state tax authority rather than relying solely on these figures. The practical takeaway is to identify any applicable state withholding early and, where possible, file the state application around the same time as the federal one, since escrow can hold both amounts simultaneously. Staggered filings tend to create two separate delays instead of one coordinated release.
Pros and Cons of Filing
Filing isn't automatic or free, so it's worth weighing. On the plus side, it frees up cash at closing instead of waiting for a refund, generally resolves faster than a full refund cycle, matches withholding to actual tax exposure rather than gross sale price, can support treaty or nonrecognition positions where they genuinely apply, and can support spreading tax over time in an installment sale structure.
On the other side, professional preparation fees are a real cost, and the process requires disclosing basis, depreciation, and other financial records to support the calculation. A missing ITIN can add weeks and put a closing date at risk. A weak or poorly documented application can leave a seller no better off, and sometimes with more delay, than simply letting the buyer withhold and filing for a refund later. And filing federally doesn't address any separate state withholding obligation.
Frequently Asked Questions
Can a green card holder use this form? No. Lawful permanent residents are treated as U.S. persons, so FIRPTA withholding doesn't apply to them.
Can the buyer remit the withholding before the IRS responds? No. Once the application is filed before closing, the buyer should hold the funds in escrow until the IRS issues its decision.
Do I still need to file a U.S. tax return after getting a certificate? Yes. The certificate only affects withholding at closing. The seller still files a U.S. return for the year of sale to report the actual gain and reconcile withholding against the real tax owed.
Does a federal certificate affect state withholding? No. State withholding regimes in California, Hawaii, Maryland, and elsewhere are separate and require their own applications if a reduction is sought.
The Bottom Line
Form 8288-B exists to correct a real structural problem in how FIRPTA withholding works: the default 15% is based on the gross sale price, not the actual gain, and that mismatch can tie up substantial cash in escrow for sellers who owe far less tax than the statutory withholding suggests. A well-built application, filed early with complete documentation and a defensible tax calculation, gives the IRS what it needs to approve a reduced amount before closing rather than forcing a seller to wait for a refund months later.
The process rewards preparation. Filing early, keeping escrow instructions explicit about when funds can actually be released, coordinating with any applicable state withholding filing, and avoiding the handful of documentation mistakes that routinely stall these applications all make the difference between a clean review and a transaction that drags on well past closing.
