How Long Does a FIRPTA Refund Take? Step-by-Step Timeline for Non-Resident Sellers

If you sold U.S. real estate as a non-resident, chances are 15% of the gross sales price got withheld at closing — often far more than you actually owe in tax. This post walks through exactly how long a FIRPTA refund takes, from the day escrow closes to the day the IRS actually cuts a check, and where the process typically stalls for sellers who don't plan ahead.

What Triggers a FIRPTA Withholding Refund in the First Place

FIRPTA — the Foreign Investment in Real Property Tax Act — requires buyers (or their closing agents) to withhold a percentage of the sales price whenever a non-resident sells U.S. real property. The default rate is 15% of the gross sales price under IRC Section 1445, though it can drop to 10% for certain properties sold for $1,000,000 or less that the buyer intends to use as a residence, and withholding can be waived entirely in narrow cases. We've broken down the mechanics of these rates in more detail in our FIRPTA withholding rate guide.

The catch: withholding is calculated on the gross sale price, not your actual gain. Sell a property for $500,000 and the title company withholds $75,000 — even if your actual taxable gain, after basis and closing costs, is only $40,000 and your real tax bill is closer to $12,000. That gap between what got withheld and what you actually owe is your refund, and claiming it back is what most of this timeline is about.

The FIRPTA Refund Timeline at a Glance: From Closing to Check

Here's how the process typically unfolds for a non-resident seller who didn't reduce withholding in advance and has to claim the full refund after the sale:

If you file Form 8288-B before closing to reduce withholding upfront, you skip the "wait a year, then claim it all back" problem — but that path has its own timeline, covered in Step 2.

Step 1: Getting Your ITIN Before You Can File for a Refund

You cannot file a 1040-NR, and you cannot receive a FIRPTA refund, without a taxpayer identification number. If you've never filed a U.S. tax return before, that means applying for an Individual Taxpayer Identification Number (ITIN) using Form W-7.

Processing time for a standalone ITIN application generally runs 7 weeks if you're applying from inside the U.S., and 9 to 11 weeks if you're applying from abroad or during peak filing season (January through April). Missing documentation, an unclear reason for applying, or errors on the W-7 will restart that clock — this is the single most common source of avoidable delay in the entire FIRPTA refund process. We cover the paperwork requirements in detail in our guide on what documents you need for an ITIN application.

One important clarification: ITINs are issued solely by the IRS. Nolly operates independently of the IRS and any government agency — our role is preparing and organizing your W-7 documentation so the application goes in clean the first time, not issuing the number itself.

If you already have an ITIN from a previous filing but haven't used it in the last three consecutive tax years, check whether it's expired before you rely on it — an expired ITIN attached to a refund claim will get the return kicked back for renewal, adding months. Our ITIN renewal guide walks through that process.

Step 2: Filing Form 8288-B for Early Withholding Reduction (If Applicable)

If you catch this before closing, Form 8288-B lets you apply for a withholding certificate that reduces the amount withheld to match your actual estimated tax liability, instead of the full 15% of gross sale price. This is the difference between waiting a year to get your money back and never having it withheld in the first place.

The catch is timing: Form 8288-B must be submitted to the IRS on or before the closing date, and the sale can't close with reduced withholding until the IRS either approves the application or 90 days pass without a response (at which point the withholding agent can release the reduced amount, per IRS instructions for Form 8288-B). In practice, many closings proceed with full withholding held in escrow while the 8288-B is pending, then release the excess once the IRS responds.

This step only works if you plan ahead — it's not available after the sale has already closed and withholding has already been remitted. If you're mid-transaction right now, this is worth flagging to your closing agent immediately; if you've already closed, skip to Step 3.

Step 3: Filing Your 1040-NR and What the IRS Reviews

If withholding wasn't reduced at closing, your refund path runs through Form 1040-NR, filed for the tax year in which the sale occurred. You can't file this early — you have to wait until the following filing season opens, generally in late January.

On the return, you report:

• The gross sales price and your adjusted basis in the property (purchase price plus qualifying capital improvements, minus depreciation if it was a rental)
• Your actual calculated gain and the resulting tax liability
• The amount already withheld and remitted via Form 8288, which counts as a payment toward your tax bill

The IRS reviews the return to verify the sale details match what was reported on Form 8288-A (the withholding statement the buyer's agent filed), confirms your ITIN and identity information line up, and checks that your basis calculations are reasonable and supported. If you're also claiming rental deductions from a prior holding period, expect the review to look at prior filings for that rental income too.

Step 4: Processing Times and Why Refunds Get Delayed

A straightforward 1040-NR filed by an existing ITIN holder, with a clean sale and no red flags, typically sees a refund in the 4-to-6-month range from filing. But several things routinely push that out much further:

• First-time ITIN + first-time 1040-NR filed together. When a W-7 is attached directly to the return instead of processed in advance, the IRS routes the return through additional manual verification. This alone can add 2 to 4 months.
• Mismatch between Form 8288-A and your reported sale price. If the withholding statement the buyer's closing agent filed doesn't match your return, the IRS will hold the refund pending clarification — sometimes requiring a written response from you.
• Missing or incomplete basis documentation. If you're claiming a lower gain because of improvements or selling costs, the IRS may request receipts or closing statements before releasing a refund.
• Filing paper instead of relying on complete, well-organized documentation. Non-resident returns generally can't be e-filed the way domestic returns can, so paper processing timelines apply by default.
• Identity verification holds. Non-resident filers occasionally get flagged for additional identity verification, which requires a response before processing resumes.

How to Track Your FIRPTA Refund Status While You Wait

The IRS's standard "Where's My Refund" tool is built for domestic e-filed returns and generally does not reliably track 1040-NR refunds or ITIN-linked returns — non-resident filers often see no useful status update there at all. More effective options:

1. Call the IRS directly to check on the status of your return, once at least 6 months have passed since filing (calling earlier usually just gets you told to wait).
2. Check for correspondence. The IRS communicates delays and requests for additional information exclusively by mail — no calls, texts, or emails. If you've moved or use a foreign address, confirm it's correctly listed on your return, since a missed notice can stall a refund indefinitely.
3. Keep a copy of your filed return and Form 8288-A on hand, since any status inquiry will require you to reference exactly what was filed and when.

Common Mistakes That Add Months to Your Refund Timeline

• Waiting until tax season to start the ITIN application. Applying for a taxpayer ID at the same time you're filing the return means the IRS processes both simultaneously, at the slower combined pace, instead of you having a ready ITIN when filing season opens.
• Underestimating basis documentation needs. Sellers who can't produce clean records of purchase price, improvements, and selling costs often see refunds held for verification that could have been avoided with organized paperwork from the start.
• Skipping Form 8288-B when the timeline allows it. If you know about the sale months in advance, not applying to reduce withholding upfront means locking up cash for a year or more that you didn't need to.
• Using an expired ITIN. As covered above, this is a full restart, not a delay — the return gets suspended until the ITIN is renewed via a new W-7.
• Filing an incomplete or inconsistent 1040-NR. Numbers that don't reconcile with the Form 8288-A on file, or missing signatures and required attachments, trigger manual review holds that can add several months.

The single biggest lever non-resident sellers control is preparation: getting an ITIN in place before you need it, gathering basis documentation before you file, and submitting a complete, internally consistent return the first time. None of that guarantees a fast refund — the IRS's own processing queue is the biggest variable, and it's entirely outside anyone's control — but it removes the delays that are self-inflicted, which in our experience are the majority of the ones sellers actually run into.
