How to Apply for a FIRPTA Withholding Certificate (Form 8288-B): Step-by-Step Guide for Non-Resident Sellers

If you're a non-resident selling U.S. real estate, the buyer's closing agent may be required to withhold 15% of your entire sales price — not your profit — and send it straight to the IRS. A FIRPTA withholding certificate (filed on Form 8288-B) is the tool that can reduce or eliminate that withholding before closing, but the application has a real timeline and real paperwork requirements that catch sellers off guard. Here's exactly what the process involves, what can go wrong, and how to plan around it.

What Is a FIRPTA Withholding Certificate and Why It Matters

The Foreign Investment in Real Property Tax Act (FIRPTA) requires buyers of U.S. real property from foreign sellers to withhold a percentage of the sales price and remit it to the IRS as a prepayment against the seller's eventual tax liability. Since February 2016, the standard withholding rate has been 15% of the gross sales price for most transactions, though a 10% rate can apply to certain property priced between $300,001 and $1,000,000 that the buyer intends to use as a residence, and no withholding is required at all if the price is $300,000 or less and the residence test is met.

The problem is that withholding is calculated on the full sales price, not on your actual gain. Sell a property for $500,000 that you bought for $480,000, and the default withholding is $75,000 — even though your real taxable gain might only be $20,000. A FIRPTA withholding certificate, applied for on Form 8288-B, lets you ask the IRS to approve a reduced withholding amount that more closely matches your actual tax liability, based on supporting calculations you submit with the application.

Who Should Apply for Form 8288-B Before Closing

Not every foreign seller needs this form, but it's worth filing in several common scenarios:

• Your actual gain is much smaller than 15% of the sales price. This is the single most common reason sellers apply — without it, you're effectively giving the IRS an interest-free loan of your own money for months.
• You have a loss on the sale. If you're selling at a loss, or breaking even, standard withholding would take a large chunk of cash out of a transaction that generates no tax liability at all.
• You're selling through a foreign-owned single-member LLC. These structures are common among non-resident Amazon sellers and e-commerce owners who've expanded into U.S. real estate; the withholding rules still apply, and the LLC's disregarded-entity status doesn't change the math.
• The buyer's closing agent won't proceed without clarity. Title companies and escrow agents are personally liable if they under-withhold, so many will withhold the full 15% by default unless you have an approved certificate in hand.

If none of these apply — for example, you're selling at a modest gain and the standard withholding roughly matches your expected tax — it may be simpler to pay the standard withholding and file for a FIRPTA refund after your tax return is processed instead.

Documents and Financial Details You'll Need to Prepare

Form 8288-B asks the IRS to verify your math, so the application needs to be built on documentation, not estimates. Have these ready before you start:

• A valid ITIN. The IRS will not process Form 8288-B for a seller without a Taxpayer Identification Number. If you don't already have one, this needs to be handled in parallel — ideally before you're close to a closing date, since ITIN processing itself typically takes 7–11 weeks.
• Purchase documents — the original settlement statement or deed showing what you paid for the property, plus the date of purchase.
• Sale contract and estimated closing statement — the agreed sales price, closing costs, and closing date.
• Cost basis records — receipts or invoices for capital improvements (a new roof, an addition, major renovations) that increase your basis and reduce taxable gain. Routine repairs and maintenance don't count.
• Depreciation records, if the property was ever used as a rental. Depreciation recapture is taxed differently and needs to be calculated separately.
• A gain/loss calculation showing sales price minus selling expenses, minus adjusted basis, to arrive at the figure that supports your requested withholding amount.
• Entity documents, if the seller is an LLC or corporation rather than an individual — formation documents and EIN confirmation.

Step-by-Step: Completing and Submitting Form 8288-B

A few details worth flagging directly on the form: Form 8288-B must identify both the transferor (seller) and transferee (buyer), describe the property, and state the withholding amount you believe is appropriate along with the legal and factual basis for it. If multiple sellers are involved — say, co-owners of a rental property — each one generally needs their own application unless they're filing jointly with matching ownership percentages clearly documented.

What Happens After Submission: Review and Processing Timeline

Once mailed, the application enters a formal 90-day IRS review clock, though many applications are resolved faster if the paperwork is clean. During this period:

• Withholding isn't skipped — it's held. The buyer or closing agent still withholds the standard 15% at closing but doesn't have to remit it to the IRS immediately. Instead, the funds sit in escrow pending the certificate decision.
• The IRS may request additional documentation. If your basis calculation looks incomplete or the improvement receipts don't add up, expect a follow-up letter rather than an outright denial — but this restarts part of the clock.
• Once decided, the escrow agent has 20 days to remit. If approved, the reduced amount is what actually gets sent to the IRS; the difference is released to the seller. If the certificate is denied, the full original withholding gets remitted instead.

This process runs on a separate timeline from any eventual tax refund you might claim on your U.S. tax return — those two things are often confused. For a walkthrough of what happens tax-return-side afterward, see How Long Does a FIRPTA Refund Take?

Common Errors That Delay or Trigger Rejection

Most delays trace back to a handful of recurring issues:

1. Missing or expired ITIN. If your ITIN has lapsed — which happens automatically after three consecutive years of non-use — the application stalls until it's renewed. (See how to renew an expired ITIN if this applies to you.)
2. Unsupported basis claims. Listing "$40,000 in renovations" without receipts or contractor invoices is a fast way to get a request for more information, adding weeks to the timeline.
3. Filing after closing instead of before. Form 8288-B must be submitted on or before the closing date. Filing late doesn't retroactively reduce withholding already remitted — you'd need to pursue a refund instead.
4. Mismatched names or entity structures. If the property title, the LLC documents, and the ITIN application don't align exactly, processors flag the inconsistency and pause review.
5. Incomplete depreciation recapture calculations. Sellers who rented the property and skip this step often submit withholding requests the IRS considers too low relative to actual tax exposure.

Handling a Closing Date Before Your Certificate Is Approved

Since IRS review can take up to 90 days, many closings happen before a decision arrives — and that's expected, not a failure. The standard practice: the buyer withholds the full 15% at closing and the closing agent holds it in escrow (rather than remitting it to the IRS) as long as the 8288-B application was filed on or before the closing date. Once the IRS responds, the escrow agent remits the approved reduced amount within 20 days and releases the rest to you.

The practical risk here is cash flow, not compliance — your funds are simply tied up longer than the transaction itself. Building a 90-day buffer into your closing timeline expectations, and confirming with your closing agent in writing that they understand the escrow procedure, avoids confusion at the settlement table.

How Nolly Supports Non-Resident Sellers Through the Application Process

Nolly prepares and organizes the documentation non-resident sellers need for Form 8288-B — compiling basis calculations, cost documentation, and the supporting statement the IRS reviews, and coordinating the ITIN piece if you don't already have one on file. We also help sellers plan the filing against their actual closing date so the escrow mechanics don't come as a surprise mid-transaction.

It's worth being clear about what this means in practice: ITINs, EINs, and FIRPTA withholding certificates are issued exclusively by the IRS, and Nolly is an independent document preparation service with no affiliation with the IRS or any government agency. Our role is getting your paperwork accurate, complete, and submitted on time — the decision itself rests entirely with the IRS. If you're heading toward a property closing and want the withholding math handled correctly the first time, that's exactly where we come in.
