Form 8288-B: How to apply for a FIRPTA withholding certificate in 2026
IRS Form 8288-B is an application for a withholding certificate that allows a foreign seller of US real property to reduce or eliminate the FIRPTA withholding amount before closing.
Here is the problem it solves. Under FIRPTA, the buyer must withhold a percentage of the gross sales price – not the gain – and remit it to the IRS on Form 8288. The default rate is 15% of the full amount realized.
That means on a $1,000,000 sale with only a $100,000 gain, the buyer withholds $150,000 at closing – even though the actual tax on that gain may be closer to $20,000.
The IRS holds that $130,000 difference until you file a nonresident tax return and claim a refund, which can take months.
Form 8288-B changes the math. You apply to the IRS before closing, document your actual gain and maximum tax liability, and – if approved – the buyer withholds only that lower amount instead of the full 15%.
FIRPTA withholding rates: What you are up against without Form 8288-B
Without a withholding certificate, the buyer must withhold the statutory FIRPTA rate from the entire gross sales price – not just your gain – which can far exceed your actual tax liability.
The table below shows the standard FIRPTA withholding tiers under Form 8288 for tax year 2025.
| Scenario | Gross sales price threshold | Withholding rate |
|---|---|---|
| Individual buyer acquires property as a residence | $300,000 or less | 0% |
| Individual buyer acquires property as a residence | $300,001–$1,000,000 | 10% |
| All other sales, or amount realized exceeds $1,000,000 | Any amount | 15% |
The $300,000 and $1,000,000 thresholds are set by statute and are not adjusted for inflation.
For the reduced rates to apply, the individual buyer or a family member must have definite plans to reside at the property for at least 50% of the days it is used during each of the first two 12-month periods after the transfer.
Reducing FIRPTA withholding through Form 8288-B is the primary way to limit how much cash the IRS holds at closing. A foreign seller on a property with a low gain relative to the sales price stands to benefit most from filing.
Who must file Form 8288-B: Eligible applicants and qualifying transactions
Any foreign person selling a US real property interest may apply for a withholding certificate on Form 8288-B, but the application must generally be submitted before or at the time of closing.
The following foreign persons are eligible to file:
- Nonresident alien individuals
- Foreign corporations
- Foreign partnerships
- Foreign trusts
- Foreign estates
Each of these must be disposing of a US real property interest, which includes direct real estate, certain leasehold interests, and stock in US real property holding corporations.
Different property ownership structures produce different withholding outcomes, so the entity type matters.
Who can file on behalf of the seller?
The transferee or their withholding agent may also file on behalf of the transferor in certain circumstances. Either party can submit the application, though the foreign seller typically initiates it, since the seller holds the basis documentation the IRS requires.
A domestic corporation that is a US real property holding corporation has its own withholding obligation under Section 1445(e)(3) when it distributes property to a foreign shareholder in redemption of stock, in liquidation, or as a distribution under Section 301 that isn't paid out of earnings and profits – generally 15% of the fair market value distributed.
The corporation, or the foreign shareholder, can file Form 8288-B under the Section 1445(e) box to request a withholding certificate that reduces this amount.
A domestic corporation making an ordinary sale of its own real property, rather than a distribution to a foreign shareholder, is a US person and simply certifies its non-foreign status instead.

Three grounds for requesting a reduced withholding certificate
The most commonly used basis for a FIRPTA withholding certificate on Form 8288-B is maximum tax liability – meaning the IRS will limit withholding to the actual capital gains tax owed, calculated using your adjusted basis and allowable deductions.
The IRS will accept a Form 8288-B application only on one of three bases:
- Maximum tax liability. The seller's maximum US tax on the disposition is less than the amount that would otherwise be withheld. This is the ground most foreign sellers use. You calculate your adjusted basis, subtract it from the amount realized, apply the applicable capital gains rates, and demonstrate that the resulting tax is lower than the default 15% withholding.
- Nonrecognition treatment or exemption from tax. The seller qualifies for a tax-free or tax-deferred transaction – such as a Section 1031 like-kind exchange – or is exempt from US tax on the gain under a specific statutory provision.
- Special installment sale rules. Under section 7 of Rev. Proc. 2000-35, a seller reporting the sale on the installment method under Section 453 can apply for reduced withholding on that basis. An agreement for the payment of tax with conforming security is a separate withholding certificate category under Treas. Reg. § 1.1445-3, but it is not available on Form 8288-B.
Step-by-step: How to complete Form 8288-B
Every line of Form 8288-B must be supported by documentation – the IRS will not approve a reduced withholding certificate without evidence of your adjusted basis and gain calculation.
The Form 8288-B instructions require seven categories of information, submitted in this sequence:
- Identify the transferor. Enter the foreign seller's name, address, and US Taxpayer Identification Number. If the seller lacks a TIN, file Form W-7 for an ITIN alongside the 8288-B application.
- Describe the US real property interest. Include the property address, the date of transfer (the closing date of this sale), and the type of interest being transferred – real property, associated personal property (such as furniture sold with the building), or an interest in a US real property holding corporation
- State the amount realized. This is generally the contract price, including cash, other property transferred, and liabilities assumed by the buyer.
- Calculate and document the adjusted basis. Start with the original purchase price, add capital improvements, and subtract accumulated depreciation. Each figure needs supporting documentation – purchase closing statements, improvement invoices, and depreciation schedules from prior US returns.
- Compute the maximum tax liability. Apply the applicable capital gains rate to the net gain. For real property with depreciation, separate the unrecaptured Section 1250 gain, which is taxed at a maximum rate of 25% (2025), from the remaining long-term capital gain, which is taxed at 0%, 15%, or 20% depending on income.
- Attach supporting documentation. Include the purchase contract, closing statement, capital improvement records, and any prior US tax returns showing depreciation claimed.
- Sign under penalties of perjury. The application must be signed by the transferor, transferee, or authorized representative.
Worked example: Calculating maximum tax liability on a US property sale
Based on a common TFX client scenario
A nonresident alien sells a US rental property for $800,000 (2025). The original purchase price was $500,000. The seller made $50,000 in documented capital improvements and claimed $70,000 in depreciation on prior US returns.
Adjusted basis: $500,000 + $50,000 − $70,000 = $480,000
Total gain: $800,000 − $480,000 = $320,000
The gain breaks into two components:
- Depreciation recapture: $70,000 taxed at the 25% maximum rate for unrecaptured Section 1250 gain = $17,500
- Remaining long-term capital gain: $250,000 taxed at 20% (the top rate, assuming the seller's income places the gain in the highest long-term capital gains bracket; sellers with lower income would use 0% or 15%) = $50,000
Maximum tax liability: $67,500
Default FIRPTA withholding at 15%: $120,000
Cash preserved by filing Form 8288-B: $52,500
In this scenario, the withholding certificate amount is a fraction of the statutory FIRPTA withholding on the gross sales price, freeing up $52,500 in cash at closing. Without the certificate, the seller would wait months for a refund after filing Form 1040-NR.
FIRPTA applies only to foreign sellers. A US citizen or green card holder selling US property is not a foreign person under FIRPTA, so no FIRPTA withholding applies to that sale. If the property was a primary residence, the seller may still qualify for the Section 121 exclusion, which can shelter up to $250,000 of gain for single filers or $500,000 for married filing jointly
Form 8288-B filing deadlines and timing requirements
Filing Form 8288-B before the closing date is critical – submitting it after the buyer has already remitted the full withholding to the IRS means you must wait for a tax refund instead of receiving reduced withholding at closing.
The critical timing rules:
- Submit on or before the transfer date. The IRS Form 8288-B should be filed on or before the date of the transfer to give the IRS time to process it before closing.
- Buyer must still withhold at closing. Even if the application is pending, the buyer withholds the statutory amount from seller proceeds at closing. The application does not pause withholding – it changes what happens to the withheld funds.
- Buyer holds funds rather than remitting immediately. If the buyer receives written notice that a Form 8288-B application has been filed before or on the transfer date, the buyer must hold the withheld funds rather than remit them to the IRS. The buyer has until the 20th day after the IRS mails the withholding certificate or denial notice to file Form 8288 and remit.
- Certificate issued – buyer remits only the certified amount. Once the IRS approves the application, the buyer remits only the amount specified in the withholding certificate. Any excess held in escrow is released to the seller.
- Certificate denied – full amount remitted. If the IRS denies the application, the buyer must remit the full withheld amount within 20 days of the denial notice.
Form 8288-B processing time: What to expect from the IRS
An incomplete Form 8288-B application – missing documentation or an incorrect TIN – is the single most common reason for IRS processing delays, which can push past your closing date.
Under Rev. Proc. 2000-35, the IRS aims to act on a complete application within approximately 90 days. In practice, processing times vary and have historically ranged from several weeks to several months depending on IRS workload and the completeness of the submission.
Two factors drive delays more than any other: missing or incorrect Taxpayer Identification Numbers and inadequate basis documentation. Applications that arrive without a valid TIN are effectively stuck until the seller obtains an ITIN on Form W-7.
Where to mail Form 8288-B: Mailing address and submission instructions
Form 8288-B must be sent to a specific IRS processing center – mailing it to the wrong address can delay your withholding certificate and jeopardize your closing timeline.
As of the current Form 8288-B revision, dated December 2025, mail the application to the address that matches your filing situation:
- Standalone Form 8288-B application: Internal Revenue Service, P.O. Box 409101, Ogden, UT 84409.
- Form 8288-B filed together with Form W-7 for an ITIN: Internal Revenue Service, ITIN Operation, P.O. Box 149342, Austin, TX 78714-9342 – not Ogden.
The IRS may update this address periodically, so verify it against the current Form 8288-B instructions before submitting.
Send the application by certified mail with return receipt requested. This creates a documented submission record with a date stamp, which is important if the IRS questions whether the application was filed before the transfer date.
Both the buyer and the seller should retain copies of all submitted materials, including the application itself, all attachments, and proof of mailing.
Form 8288-A vs. Form 8288-B: Understanding the difference
Form 8288-A is filed by the buyer to report withholding already made, while Form 8288-B is filed by the seller to request that withholding be reduced before it is ever remitted to the IRS.
Both forms are part of the same FIRPTA compliance framework, alongside Form 8288 as the parent withholding return. The table below shows how they differ.
| Feature | Form 8288-A | Form 8288-B |
|---|---|---|
| Who files | Buyer or withholding agent | Foreign seller or buyer |
| Purpose | Statement of withholding already made | Application to reduce or eliminate withholding before remittance |
| Timing | Filed with Form 8288 within 20 days of transfer | Filed before or on the transfer date |
| Outcome | Documents the withholding amount per seller; IRS stamps and returns Copy B to the seller | Results in a withholding certificate specifying a reduced amount |
The IRS stamps Copy B of Form 8288-A and returns it to the foreign seller after processing. That stamped copy is the seller's proof of withholding when claiming a credit on the nonresident tax return.
Form 8288-B, by contrast, is filed before the withholding happens – or at least before the buyer remits it. The goal is to reduce the amount before it ever reaches the IRS.
Treaty benefits and FIRPTA exemptions that can eliminate withholding entirely
A treaty rarely eliminates FIRPTA withholding on a real property sale outright, and the IRS scrutinizes treaty-based claims carefully and requires detailed documentation.
IRC Section 897 treats the gain as effectively connected income regardless of treaty status, and most treaties preserve the source country's right to tax real property gains. A treaty can still support a FIRPTA withholding certificate on Form 8288-B in narrower cases, such as where nonrecognition provisions apply.
A US tax treaty typically addresses real property gains directly in its capital gains article, which allows the country where the property sits to tax the gain – which is why a treaty rarely eliminates FIRPTA withholding on a real estate sale.
The specific treaty article must be cited in the application, and the seller must demonstrate that they are a qualifying resident of the treaty country.
Beyond treaties, a seller may qualify for zero withholding if the transaction is fully covered by a nonrecognition provision – for example, a complete Section 1031 like-kind exchange where no boot is received.
See our TFX guide to common international tax forms and foreign withholding forms for the broader set of forms that arise in cross-border transactions.
The transferee's role: withholding agent responsibilities under FIRPTA
The buyer is personally liable for FIRPTA withholding – if the buyer fails to withhold and remit the required amount, the IRS can collect the tax directly from the buyer, not just the foreign seller.
The buyer's obligations under IRC § 1445:
- Verify seller status. Determine whether the seller is a foreign person before closing.
- Withhold the correct amount. Withhold the required statutory amount from the amount realized.
- File within 20 days. File Form 8288 and Form 8288-A with the IRS within 20 days of the transfer.
- Remit or hold. Remit withheld funds within that same 20-day period, unless a Form 8288-B application is pending and the buyer has received proper written notice.
- Escrow pending applications. Hold withheld funds in escrow if a Form 8288-B application is pending rather than remitting them immediately.
If the buyer fails to withhold when required, the IRS can pursue the buyer for the full amount that should have been withheld, plus interest and applicable penalties. This is true even if the seller has left the country.
The IRS has targeted nonresident aliens with US rental property in recent compliance campaigns, making thorough documentation at closing critical.
What happens after the IRS issues a withholding certificate
A withholding certificate does not eliminate your US tax filing obligation – you must still file a nonresident US tax return for the year of sale and reconcile the withholding against your actual tax liability.
Once the IRS issues a withholding certificate specifying the approved withholding amount, the closing process completes in one of two ways:
If the buyer has been holding the withheld funds pending the IRS decision, the buyer remits only the certified amount and releases the balance to the seller.
If the full amount was already remitted to the IRS before the certificate was issued, the seller must recover the excess through the annual tax return – the same outcome as not filing Form 8288-B at all.
The seller must still file Form 1040-NR for the year of the sale, reporting the gain and claiming credit for any withholding paid.
Any excess withholding over the final tax liability results in a refund when the return is processed.
See our TFX guide on FIRPTA for a complete walkthrough of the end-to-end withholding and return-filing process.
FIRPTA and 1031 like-kind exchanges: can you defer and avoid withholding?
A properly structured 1031 exchange combined with a Form 8288-B application can allow a foreign seller to defer capital gains tax and avoid FIRPTA withholding on the exchanged portion of the gain simultaneously.
A foreign seller who qualifies for a Section 1031 like-kind exchange may use Form 8288-B to claim nonrecognition treatment as the basis for a withholding certificate.
This can reduce withholding to zero on the deferred gain portion.
The exchange must be fully structured and documented before the Form 8288-B application is submitted. A partial exchange – where the seller receives cash or other non-like-kind property – results in boot that remains subject to withholding.
Two requirements must both be satisfied: the exchange must meet all Section 1031 requirements independently, and the Form 8288-B application must demonstrate that nonrecognition applies to the specific gain.
Foreign-to-US or US-to-foreign real property exchanges do not qualify as like-kind exchanges. After the Tax Cuts and Jobs Act, Section 1031 applies only to real property. Separately, under IRC § 1031(h), US and foreign real property are never considered like-kind to each other.
Net investment income tax and its interaction with FIRPTA withholding
Correctly calculating maximum tax liability for Form 8288-B requires accounting for all applicable federal taxes on the gain, including depreciation recapture rates and the Net Investment Income Tax where it applies, not just the federal capital gains rate.
Nonresident aliens are generally not subject to the Net Investment Income Tax on US real property gains. IRC § 1411 explicitly exempts nonresident aliens from the 3.8% NIIT.
Foreign sellers who are resident aliens or who have a dual-status year should verify their NIIT exposure when calculating maximum tax liability for Form 8288-B purposes.
If the seller's modified adjusted gross income exceeds $200,000 for single filers or $250,000 for married filing jointly, the 3.8% NIIT (2025) may apply on top of the capital gains rate.
State-level FIRPTA-equivalent withholding requirements exist in some states and must be addressed separately from the federal Form 8288-B. A withholding certificate from the IRS does not reduce or eliminate any state-level obligation.
Common mistakes that get Form 8288-B applications rejected
The IRS will reject a Form 8288-B application that lacks a valid US Taxpayer Identification Number for the foreign seller – obtaining an ITIN before filing is a non-negotiable prerequisite.
The most frequent rejection reasons:
- Missing or incorrect TIN. The foreign seller must have a valid SSN or ITIN. An application without one is treated as incomplete and will not be processed. If you do not have a US TIN, file Form W-7 for an ITIN alongside the 8288-B application.
- Failure to attach the purchase contract or closing statement. The IRS requires documentation of the amount realized and the original purchase price. Without these, the adjusted basis calculation cannot be verified.
- Inadequate documentation of capital improvements. Claiming $50,000 in improvements without invoices, permits, or contractor records is insufficient. The IRS expects third-party documentation for every improvement added to the basis.
- Incorrect calculation of depreciation recapture. If the seller claimed depreciation on prior US returns, the accumulated depreciation must be subtracted from the basis and the recapture portion taxed at the 25% maximum rate. Failing to account for this overstates the basis and understates the maximum tax liability.
- Submitting after the buyer has already remitted withholding to the IRS. At that point, the Form 8288-B process is moot – the seller must file Form 1040-NR and claim a refund instead.
- Failure to sign the application under penalties of perjury. An unsigned application is incomplete.
Form 8288-B for foreign corporations and partnerships selling US real property
A foreign corporation selling US real property must account for both the corporate-level capital gains tax and the potential branch profits tax when calculating maximum tax liability for Form 8288-B.
Foreign corporations and foreign partnerships that dispose of US real property interests are subject to FIRPTA withholding and may file Form 8288-B to request a withholding certificate. The calculation of maximum tax liability differs from individual sellers in several ways.
A foreign corporation pays US tax on effectively connected income at the 21% corporate rate for tax year 2025.
The branch profits tax under IRC § 884 imposes an additional 30% tax on the dividend equivalent amount – unless a tax treaty reduces that rate. Both taxes must be factored into the maximum tax liability calculation on Form 8288-B.
The entity's EIN – not an individual ITIN – must be used on the application. Foreign partnerships should use their partnership EIN and include each foreign partner's allocable share of gain in the calculation.
The entity's tax treaty position may differ from that of its individual owners. A foreign corporation resident in a treaty country may claim treaty benefits at the entity level, while its shareholders may be residents of different countries with different treaty positions.
Transfers of partnership interests with effectively connected gain follow a separate withholding framework under Section 1446(f), not Form 8288-B.
Most transfers are reported on Forms 8288 and 8288-A, the same forms used for standard FIRPTA withholding. Form 8288-C applies only in the narrower case under Section 1446(f)(4), where the partnership itself must withhold from distributions to a transferee who failed to withhold.
What if you already paid full FIRPTA withholding? Claiming a refund
Filing a US nonresident tax return is the only way to recover excess FIRPTA withholding after it has been remitted to the IRS – and the refund process typically takes several months after the return is filed.
If the full FIRPTA withholding was remitted to the IRS before a withholding certificate was obtained, the foreign seller cannot recover the excess through Form 8288-B. The only path is:
- File Form 1040-NR for the year of the sale.
- Report the gain and calculate the actual tax owed.
- Claim the withheld amount as a credit against the tax due, using the stamped Copy B of Form 8288-A as documentation.
- Any excess withholding over the final tax liability is refunded after the IRS processes the return.
The refund timeline depends on IRS processing speed, but several months from filing to refund is typical for nonresident returns.
See our TFX guide on Form 1040-NR for the broader rules on reporting the sale and claiming your withholding credit.
Form 8288-B and inherited US real property: special considerations
Inherited US real property typically receives a stepped-up basis to fair market value at the date of the decedent's death, which can dramatically reduce the taxable gain and the withholding certificate amount on Form 8288-B.
Foreign persons who inherit US real property and subsequently sell it are subject to FIRPTA withholding on the disposition. The Form 8288-B application for inherited property uses the stepped-up basis under IRC § 1014 rather than the decedent's original purchase price.
If the property's fair market value at the date of death was close to the eventual sale price, the taxable gain may be minimal – making the maximum tax liability far lower than the default 15% withholding.
A withholding certificate in this scenario can reduce withholding to a small fraction of the sales price.
The estate may also have had separate FIRPTA obligations at the time of the decedent's death if the property passed to a foreign beneficiary through a distribution that constituted a disposition of a US real property interest.
See our TFX guide on how to avoid paying capital gains tax on inherited property for the full stepped-up basis rules and their interaction with FIRPTA.
Frequently asked questions
Form 8288-B is the application a foreign seller files to request a withholding certificate that reduces or eliminates the default FIRPTA withholding on a US real property sale. The IRS issues the certificate after reviewing the seller's tax liability calculation and documentation.
Either the buyer or the seller can file. In practice, the foreign seller typically initiates the application because the seller holds the basis documentation – purchase records, improvement receipts, and depreciation schedules – that the IRS requires to evaluate the request.
Under Rev. Proc. 2000-35, the IRS aims to act on a complete application within approximately 90 days. Incomplete applications – particularly those missing a valid TIN or basis documentation – can take significantly longer.
You can, but it is far less useful. If the buyer has already remitted the full withholding to the IRS, the Form 8288-B process cannot recover those funds. You would instead need to file Form 1040-NR and claim a refund, which takes months.
The IRS Form 8288-B instructions list the required attachments: the signed purchase contract, closing statement, improvement records, depreciation schedules, and a maximum tax liability computation. An incomplete application will be rejected.
Form 8288 is the withholding return the buyer files to remit FIRPTA withholding to the IRS. Form 8288-A is the buyer's statement documenting the withholding for each foreign seller. Form 8288-B is the seller's application to reduce or eliminate the withholding before it is remitted.
Yes. A withholding certificate reduces withholding at closing but does not eliminate your US tax filing obligation. You must file Form 1040-NR for the year of the sale, report the gain, and reconcile the withholding credit against your actual tax liability.
