You file IRS Form 8288-B to ask the IRS for a withholding certificate that reduces or eliminates the 15% FIRPTA tax that a buyer must otherwise hold back when a foreign person sells U.S. real estate. The form lets the seller prove that the actual tax owed on the sale is less than the standard withholding amount, so the IRS can release the excess cash at closing instead of trapping it for a year.
If you are a foreign seller, missing this filing means a U.S. buyer will hand 15% of the gross sale price to the IRS under IRC §1445, even when your real tax bill is far smaller. According to the most recent IRS SOI data on FIRPTA collections, the IRS withholds more than $1.2 billion each year from foreign real estate sellers, and a large share of that money sits idle for 12 to 18 months before refund.

What Form 8288-B Actually Does
IRS Form 8288-B is the Application for Withholding Certificate for Dispositions by Foreign Persons of U.S. Real Property Interests. The form asks the IRS to approve a reduced withholding amount, or zero withholding, before the closing of a U.S. real estate sale. Without this certificate, the buyer must follow the default rule in Treasury Regulation §1.1445-1 and send 15% of the gross sale price to the IRS within 20 days of closing.
The certificate matters because the default 15% rate applies to the sale price, not the profit. A foreign seller who paid $900,000 for a home and sells it for $1,000,000 still faces $150,000 in withholding, even though the actual gain is only $100,000. The plain-English idea is simple: the IRS holds extra cash as a deposit until the seller files a U.S. tax return the next year. The consequence of skipping the application is a long wait for a refund, often more than a year, with no interest paid on the trapped money. A common misconception is that Form 8288-B eliminates the tax. It does not. It only adjusts the amount held back at closing.
The legal authority comes from IRC §1445(c)(3), which lets the IRS issue a certificate when the seller’s maximum tax liability is less than the standard withholding. The rule exists because Congress wanted to stop foreign owners from leaving the country before paying U.S. tax, but it also wanted to avoid over-collecting from honest sellers. The consequence of ignoring the option is real: a foreign retiree selling a Florida condo at a small gain can lose the use of $75,000 in cash for 14 months. A typical example is Maria, a Canadian who sells her Miami condo. Maria can apply on Form 8288-B, prove her real tax is $9,000, and have the buyer release the rest at closing.
Who Must File and Who May File
A foreign seller files Form 8288-B to request a reduced rate, while the buyer files Form 8288 and Form 8288-A to report the actual withholding. The seller is the transferor in IRS language, and the buyer is the transferee. A foreign person includes a nonresident alien individual, a foreign corporation, a foreign partnership, a foreign trust, or a foreign estate, as defined in Treas. Reg. §1.1445-2(b).
The consequence of misidentifying the parties is delay. The IRS rejects the application if the wrong person signs. A real example is Lin Wei, a Chinese national who owned a Seattle rental through a single-member LLC. Because the LLC is disregarded, Lin Wei files in her own name, not the LLC’s, under Treas. Reg. §301.7701-3. A common misconception is that a green card holder must file Form 8288-B. They do not, because lawful permanent residents are U.S. persons and FIRPTA does not apply.
When the Certificate Must Reach the IRS
The seller must mail or fax the application to the IRS no later than the day of closing, per the instructions to Form 8288-B. The IRS then has 90 days to act, although 2026 processing times often run longer because of staffing changes at the Ogden service center. While the application is pending, the buyer still must hold the 15% in escrow, but the buyer does not send the money to the IRS yet.
The plain-English rule is that you keep the cash parked until the IRS answers. The consequence of sending the money early is that the buyer loses the right to wait, and the seller loses the chance for a quick release. A real example is Pieter, a Dutch citizen, who closed on October 1, 2026, and faxed Form 8288-B on September 30, 2026; the buyer’s title company held the $90,000 in escrow until the IRS answered on December 12, 2026. A common misconception is that filing late still helps. It does not, because once the buyer remits the money, the seller must wait for a Form 1040-NR refund.
Line-by-Line Walkthrough of Form 8288-B
The current version of Form 8288-B has one page with about 20 numbered lines, plus a signature block and an attachments list. Each line carries a specific consequence if you leave it blank or guess. The IRS rejects incomplete applications and does not call you to fix them. You learn about the rejection only when the buyer’s 15% hits the U.S. Treasury.
Header Boxes: Category and Identity
The top of the form asks you to check one of six category boxes that match the legal basis for the request. Most foreign sellers check Category 4, which covers a claim that the maximum tax owed is less than the standard withholding. Category 1 covers exemption under a treaty. Category 2 covers a non-recognition transaction such as a like-kind exchange. Category 3 covers an agreement to pay tax later, called a security agreement.
The consequence of choosing the wrong category is automatic denial. A real example is Hiroshi, a Japanese investor who tried to claim a treaty exemption under Category 1 when no treaty actually applied; the IRS denied his application and the buyer remitted $112,500. A common misconception is that you can check more than one box. You cannot, because each category has a different evidence list. Pick the single rule that fits your sale.
The identity boxes ask for the seller’s name, U.S. taxpayer identification number (TIN), foreign address, and U.S. address if any. A foreign individual without a Social Security number must apply for an Individual Taxpayer Identification Number (ITIN) using Form W-7, and the W-7 may be filed with the 8288-B package. The plain-English point is that no TIN means no certificate. The consequence is a frozen application until the ITIN issues, which can add 8 to 11 weeks.
Lines 1 Through 3: The Property and the Parties
Line 1 asks for the seller’s name and TIN. Line 2 asks for the buyer’s name, TIN, and address. Line 3 asks for the property’s full street address, legal description, and use, such as personal, rental, commercial, or vacant land. The legal description should match the deed and survey, not just the mailing address.
The consequence of mismatched addresses is a request for more information, called an RFI, which adds at least 30 days. A real example is Sofia, a Brazilian seller of a Manhattan co-op, who wrote only “Apt 14B” without the block and lot number; the IRS sent an RFI and the closing money sat for 75 extra days. A common misconception is that the use code does not matter. It does, because personal-use property under $300,000 may qualify for the buyer’s residence exemption and a different rate.
Lines 4 Through 6: Sale Price, Basis, and Gain
Line 4a asks for the date of transfer, which is the closing date. Line 4b asks for the amount realized, which is the gross sale price plus any debt the buyer assumes, under IRC §1001(b). Line 5 asks for the seller’s adjusted basis, which is the original purchase price plus capital improvements, minus depreciation taken or allowable under IRC §1016.
The plain-English rule is that the gain on Line 6 equals Line 4b minus Line 5. The consequence of overstating the basis is denial and possibly a fraud referral under IRC §6663. A real example is Klaus, a German owner of a Tampa duplex, who forgot to subtract $48,000 of allowed depreciation; the IRS recalculated, raised the gain, and denied the lower rate. A common misconception is that you can ignore depreciation if you never claimed it. You cannot, because the statute uses the words “allowed or allowable.”
Lines 7 Through 12: Maximum Tax Liability
These lines compute the maximum tax liability, which is the highest tax the seller could owe on the sale. For a long-term capital gain held more than one year, an individual non-resident pays 20% on the gain above the top bracket, plus a depreciation recapture rate of 25% on prior depreciation under IRC §1250. A foreign corporation pays the flat 21% corporate rate under IRC §11.
The plain-English idea is that the IRS will not accept a number lower than the worst-case tax. The consequence of a number that is too low is denial. A real example is Amélie, a French seller of a Boston brownstone, who used the 15% long-term rate when her bracket actually triggered 20%; the IRS adjusted her certificate from $42,000 to $56,000. A common misconception is that the Net Investment Income Tax (NIIT) of 3.8% applies. It does not, because nonresident aliens are not subject to NIIT under IRC §1411(e).
Signature, Penalties, and Attachments
The seller, or an authorized agent under a Form 2848 Power of Attorney, must sign the form under penalty of perjury. The consequence of an unsigned form is automatic rejection. The consequence of a false statement is criminal exposure under IRC §7206, which carries up to three years in prison.
Attachments must include a closing statement, the deed history, basis records, depreciation schedules, and any prior-year Form 1040-NR returns. The IRS instructs filers to mail to the Ogden, Utah service center or fax to the dedicated FIRPTA unit. A common misconception is that emailed PDFs are accepted. They are not, because the IRS does not accept email submissions for 8288-B as of 2026.
Three Common Scenarios with Dollar Math
The scenarios below show how the math actually plays out. Each one uses 2026 rates and current IRS processing rules.
Scenario 1: Small Gain on a Personal-Use Condo
| Step | Outcome |
|---|---|
| Maria, a Canadian, sells her Miami condo for $600,000 | Gross withholding at 15% would be $90,000 |
| Adjusted basis is $540,000, so gain is $60,000 | Maximum long-term tax at 20% equals $12,000 |
| Maria files Form 8288-B requesting $12,000 | IRS approves, buyer releases $78,000 at closing |
Scenario 2: Large Depreciation Recapture on a Rental
| Step | Outcome |
|---|---|
| Lin Wei, a Chinese national, sells a Seattle duplex for $1,400,000 | Gross withholding at 15% would be $210,000 |
| Basis is $900,000, depreciation taken is $180,000, gain is $680,000 | Recapture at 25% on $180,000 plus 20% on $500,000 equals $145,000 |
| Lin Wei files Form 8288-B requesting $145,000 | IRS approves, buyer releases $65,000 at closing |
Scenario 3: Foreign Corporation Sells Commercial Property
| Step | Outcome |
|---|---|
| BV Holdings, a Dutch corporation, sells a Dallas warehouse for $5,000,000 | Gross withholding at 15% would be $750,000 |
| Basis is $4,200,000, gain is $800,000, corporate rate is 21% | Maximum tax equals $168,000 |
| BV Holdings files Form 8288-B requesting $168,000 | IRS approves, buyer releases $582,000 at closing |
Treaty Claims and Special Cases
Some foreign sellers can use a U.S. tax treaty to reduce or eliminate the tax. The key point is that most treaties do not override FIRPTA, because the Technical and Miscellaneous Revenue Act of 1988 preserves U.S. taxing rights on real property gains. The consequence of an incorrect treaty claim is a denial under Category 1, plus possible penalties under IRC §6662.
Like-Kind Exchanges Under Section 1031
A foreign seller swapping U.S. real estate for other U.S. real estate may qualify for non-recognition under IRC §1031. The seller checks Category 2 and attaches the qualified intermediary’s exchange agreement. The consequence of a botched 45-day or 180-day deadline is full FIRPTA withholding on the cash boot. A real example is Carlos, a Mexican investor, who exchanged a Phoenix duplex for a San Antonio rental; he received zero boot and the IRS approved a zero-withholding certificate.
Installment Sales and Seller Financing
When the seller takes back a note, the IRS still bases withholding on the gross price, not the cash received at closing. The seller can use Form 8288-B to spread tax under IRC §453 and post a security agreement under Category 3. The consequence of skipping the security agreement is that the buyer must withhold 15% of the full price even though only a down payment changed hands. A real example is Yuki, a Japanese seller, who financed 70% of a $2 million sale and used a security agreement to cap withholding at the cash actually received.
The Buyer’s Personal Residence Exemption
If the buyer plans to live in the property as a residence and the price is $300,000 or less, withholding is zero under Treas. Reg. §1.1445-2(d)(1). If the price is between $300,001 and $1,000,000, the rate drops to 10%, not 15%. The consequence of a buyer signing the residence affidavit and then renting the property is personal liability for the unwithheld tax.
Mistakes to Avoid
These errors cause most denials and delays. Each one has a specific negative outcome.
- Filing after closing: The buyer must remit the 15%, and the seller waits for a refund.
- Using the wrong category box: The IRS rejects without a phone call.
- Forgetting depreciation recapture: The maximum tax is too low and the IRS denies.
- Mismatching the property’s legal description: An RFI adds 30 to 60 days.
- Skipping the ITIN application: The IRS freezes the file until Form W-7 clears.
- Claiming a non-existent treaty benefit: The IRS may impose accuracy penalties.
- Sending an unsigned form: The package is treated as never filed.
- Overstating basis with no records: The IRS requests proof and may refer for fraud.
- Ignoring state withholding: California, Hawaii, and Maryland have separate rules.
- Letting the buyer remit early: The seller loses the chance for a closing release.
Do’s and Don’ts for Foreign Sellers
These rules come from the Form 8288-B instructions and current IRS practice in 2026.
- Do apply for an ITIN early, because processing takes 8 to 11 weeks.
- Do gather basis records before listing, because the IRS demands proof at filing.
- Do include depreciation schedules, because allowable depreciation reduces basis.
- Do use a qualified intermediary for any 1031 exchange, because direct receipt of cash kills the deferral.
- Do keep the closing money in escrow until the IRS answers, because early remittance ends the option.
- Don’t sign a buyer’s residence affidavit unless the buyer truly will reside in the home.
- Don’t rely on a tax treaty without checking the savings clause.
- Don’t ignore state forms such as California Form 593.
- Don’t use a power of attorney that is not on Form 2848, because other formats are rejected.
- Don’t forget to file Form 1040-NR the next year, because the certificate is not the final return.
Pros and Cons of Filing Form 8288-B
The decision to file is not automatic. Some sellers benefit, while others should let the buyer simply withhold and chase a refund.
- Pro — Cash freed at closing: The seller keeps liquid funds for the next purchase.
- Pro — Shorter wait: The IRS answers in about 90 days, faster than a refund cycle.
- Pro — Smaller tax exposure: The seller pays only the real tax, not 15% of gross.
- Pro — Treaty leverage: Some sellers can claim a true exemption.
- Pro — Installment relief: Section 453 spreads the tax over years.
- Con — Filing cost: Professional fees often run $1,500 to $4,000.
- Con — Disclosure: The seller must hand over basis and depreciation records.
- Con — ITIN delay: A missing TIN can stall a closing.
- Con — Risk of denial: A weak file leaves the seller worse off than if the buyer had simply remitted.
- Con — State overlap: Federal relief does not cure state withholding.
State Withholding That Stacks on Top of FIRPTA
Federal law sets the floor, but several states add their own withholding. California’s Real Estate Withholding Statement Form 593 requires 3.33% of the sale price unless a reduced rate is approved. Hawaii’s HARPTA rules under Form N-288B require 7.25% withholding. Maryland’s Form MW506NRS requires 8% for individuals and 8.25% for entities.
The plain-English point is that a federal certificate does not cancel state withholding. The consequence of forgetting state forms is a second escrow hold, sometimes equal to or larger than the federal one. A real example is Helena, a Swiss seller in Honolulu, who got federal relief but forgot HARPTA; the state held $36,250 for nine months. A common misconception is that all states follow IRS rulings. They do not, because each state has its own statute, administrative process, and forms.
Coordinating Federal and State Filings
The smart play is to file the federal Form 8288-B and the state withholding application on the same day. Each agency reviews independently, but the closing escrow can hold both amounts at once. The consequence of staggered filings is two separate delays. A real example is Anders, a Swedish seller in Los Angeles, who filed federal in March and California in May; the May filing pushed the cash release to August.
Court Rulings and IRS Guidance
Several rulings shape how the IRS treats Form 8288-B today. In Indmar Products Co. v. Commissioner, the Tax Court emphasized that taxpayers bear the burden of proving basis. The plain-English consequence is that weak records doom an application. The IRS also issued Revenue Procedure 2000-35, which sets the rules for security agreements under Category 3.
Private Letter Ruling 200052036 confirms that a foreign partnership selling a U.S. building must allocate gain to each partner before applying for a certificate. A common misconception is that one partnership-level certificate covers all partners. It does not, because each partner has a different tax profile.
Frequently Asked Questions
Can I file Form 8288-B after closing?
No. The IRS instructions require filing by the day of closing, and a late application means the buyer must remit the 15% to the Treasury and the seller must wait for a refund.
Do I need an ITIN to file Form 8288-B?
Yes. Every foreign seller without a Social Security number must apply for an ITIN on Form W-7, and the form may be submitted with the 8288-B package.
Is the 15% FIRPTA rate ever reduced automatically?
Yes. The rate drops to 10% when the price is between $300,001 and $1,000,000 and the buyer signs a residence affidavit, and it drops to zero when the price is $300,000 or less.
Does a tax treaty eliminate FIRPTA withholding?
No. Almost every U.S. tax treaty preserves U.S. taxing rights on real property gains, so a treaty rarely cancels Form 8288 withholding by itself.
Can a green card holder use Form 8288-B?
No. Lawful permanent residents are U.S. persons, FIRPTA does not apply to their sales, and Form 8288-B is not the right form for them.
How long does the IRS take to answer?
Yes, the IRS aims to act within 90 days, but 2026 processing at the Ogden service center often runs 100 to 130 days because of staffing changes.
Can the buyer remit the 15% before the IRS responds?
No. Once the seller files Form 8288-B before closing, the buyer must hold the funds in escrow until the IRS issues or denies the certificate.
Do I still file a U.S. tax return after a certificate?
Yes. The seller must file Form 1040-NR or Form 1120-F the next year to report the sale, claim the actual tax, and reconcile any over- or under-withholding.
Are state withholding rules waived by Form 8288-B?
No. Federal certificates have no effect on California, Hawaii, Maryland, or other state withholding, and a separate state application is required.
Can a single-member LLC file in its own name?
No. A foreign-owned single-member LLC is disregarded for federal tax, so the foreign owner files Form 8288-B in their own name and uses their own TIN.
Does the IRS accept emailed Form 8288-B submissions?
No. As of 2026, the IRS accepts only mail or fax submissions to the Ogden service center, and emailed PDFs are not processed.
Can a power of attorney sign Form 8288-B for me?
Yes. A representative may sign with a properly completed Form 2848, but only enrolled agents, CPAs, attorneys, and certain family members qualify under the IRS rules.
