Claiming a FIRPTA Refund on 1040-NR: Turning $97,500 Withheld Into a $86,000 Refund
FIRPTA withholding is a deposit against your real tax, not the tax itself. If 15% of your sale price was withheld but your actual capital-gains tax is far smaller, you claim the difference back by filing Form 1040-NR for the year of sale and attaching the stamped Copy B of Form 8288-A as proof. In the example below, $97,500 withheld against an $11,500 true tax produces roughly an $86,000 refund.
Why the IRS is holding far more than you owe
When a foreign person sells U.S. real estate, the buyer is legally required to withhold a percentage of the gross sale price (the "amount realized") and send it to the IRS. The standard FIRPTA rate is 15% of the amount realized on most dispositions. (IRS — FIRPTA withholding.)
The critical thing to understand: that 15% is calculated on the full price, with zero regard for your purchase price, your improvements, your closing costs, or your actual profit. The IRS withholds against the worst-case scenario and then refunds you the excess once you file a return that shows what you really owe. The tax you genuinely owe is based on your gain — and gain is almost always a fraction of the sale price.
FIRPTA withholding is exactly like the federal income tax withheld from a paycheck. Your employer doesn't know your deductions, so they over-withhold; you file a return in the spring and get money back. Same mechanism here — except the "paycheck" is a real-estate closing, the withholding rate is brutal, and the only way to see your money again is to file Form 1040-NR.
The full worked example: Marisol's Florida condo
Marisol is a nonresident of the United States who lives in Mexico City. In 2025 she sold a Florida condo she had owned as an investment for several years. Here is exactly what happened at closing and at tax time.
The closing (2025): Marisol sold the condo for $650,000. Because she sold it as an investment property — the buyer did not sign a residence affidavit and the sale was a straightforward investment disposition — the standard 15% FIRPTA rate applied to the full price:
$650,000 × 15% = $97,500 withheld and remitted to the IRS via the buyer's Form 8288 / 8288-A.
Her actual gain: Marisol bought the condo for $540,000, put $25,000 of capital improvements into it (a documented kitchen and HVAC replacement, which add to basis), and paid $39,000 in selling costs (6% agent commission plus closing fees). Her adjusted basis is therefore $540,000 + $25,000 = $565,000.
| Step | Amount |
|---|---|
| Sale price (amount realized) | $650,000 |
| Less: selling costs (commission + closing) | −$39,000 |
| Net amount realized | $611,000 |
| Less: adjusted basis (cost + improvements) | −$565,000 |
| Real long-term capital gain | $46,000 |
The real tax: Marisol held the condo more than a year, so the gain is long-term. After her allowable items, her taxable income falls into the 15% long-term capital-gains band for 2026 filers (the 0% band tops out around $49,450 of taxable income; above that you reach 15%). (IRS Topic 409 — Capital gains and losses.) A reasonable effective result on a $46,000 gain lands at roughly:
≈ $11,500 in actual U.S. capital-gains tax.
The refund: $97,500 already sitting at the IRS, minus the ~$11,500 she truly owes:
$97,500 − $11,500 ≈ $86,000 refunded.
The exact tax depends on Marisol's full-year facts — other U.S.-source income, the precise application of the rate bands, depreciation she claimed in prior years (which gets "recaptured" and taxed at a higher rate), and any state tax. The shape, though, is the point: a six-figure withholding collapses to a low-five-figure liability, and the gap comes back to her. Do not treat the $11,500 as a fixed answer for your own sale — it is illustrative. The mechanism is identical for everyone; the numbers are yours.
Calculating the real gain — the number that sets your true tax
Your refund is entirely driven by how small you can correctly make your taxable gain. The formula the IRS uses on Schedule D / Form 8949 attached to your 1040-NR:
| Line | What goes here |
|---|---|
| Sale price | The gross "amount realized" — same figure FIRPTA was withheld against |
| − Selling expenses | Real-estate commission, title fees, transfer taxes, attorney fees at sale |
| − Adjusted basis | Original purchase price plus capital improvements plus certain acquisition costs, minus depreciation taken |
| = Capital gain | The figure that is actually taxed (long-term if held >1 year) |
Two line items quietly rescue most sellers:
- Capital improvements raise your basis. A new roof, a renovation, an addition — these are added to what you paid. Keep invoices; the IRS can ask. Routine repairs do not count, but structural improvements do.
- Selling costs come straight off the top. A 5–6% agent commission alone often knocks tens of thousands off the gain.
If you rented the property out and claimed (or should have claimed) depreciation, that depreciation reduces your basis and is "recaptured" — taxed at a maximum 25% rate rather than the lower long-term capital-gains rate. This can raise the true tax above a naive estimate, so a rental property's real liability is rarely as clean as Marisol's. Run the numbers with a cross-border tax preparer before assuming the full gap comes back. (IRS Pub. 544 — Sales and Other Dispositions of Assets.)
How you actually claim it: Form 1040-NR + stamped Form 8288-A
This is the part people get wrong and lose months over. You do not "apply for a FIRPTA refund." You file your regular nonresident income tax return for the year of the sale, report the sale, compute the small real tax, and claim the large withholding as a credit. The refund is just the difference.
Step 1 — Get a U.S. taxpayer ID (ITIN) first
You cannot claim the credit without a U.S. Taxpayer Identification Number. Most foreign sellers need an ITIN (Form W-7). Critically, the IRS will not even mail you a stamped Form 8288-A if your TIN was missing from it — they hold the document and write to you asking for the number. (IRS — Instructions for Form 8288.) Sort the ITIN out early; it is the single most common cause of stalled refunds.
Step 2 — Attach the stamped Copy B of Form 8288-A
After the closing, the buyer files Form 8288 and Form 8288-A reporting your withholding. The IRS processes it and mails you a stamped Copy B of Form 8288-A. That stamped copy is your receipt — your proof that $97,500 is sitting in the system under your name. The official instruction is explicit:
"To receive credit for the withheld amount, the transferor must generally attach the stamped Copy B of Form 8288-A to a U.S. income tax return (for example, Form 1040-NR or 1120-F)." (IRS — Instructions for Form 8288.)
If you never received a stamped copy (common when the buyer botched the filing or your TIN was missing), you can still substantiate the withholding, but it slows things down. Chase the stamped copy; if it does not come, attach the closing settlement statement and the buyer's evidence of payment, and be ready for IRS correspondence.
Step 3 — File the return and let the credit flow through
On Form 1040-NR you report the sale (via Schedule D / Form 8949), arrive at the ~$11,500 tax, and enter the $97,500 of FIRPTA withholding as tax already paid. The return computes the overpayment automatically and you elect to have it refunded. (IRS — About Form 1040-NR.)
Why you must wait until the tax year is over to file
Here is the timing trap. FIRPTA is collected at closing, which can be any month. But the refund mechanism is your annual income tax return — and you cannot file a 2025 Form 1040-NR until the 2025 tax year has ended. If Marisol sold in March 2025, she still had to wait until the 2025 filing season opens in early 2026 to file the return that triggers her refund.
This is by design. The return reconciles the entire year — all your U.S.-source income, all your deductions, the full rate bands — and the IRS will not refund off a partial-year snapshot. The withholding sits in your IRS account, earning you nothing, until you file.
If you want to avoid the wait entirely, the time to act is before the sale closes: file Form 8288-B (Application for Withholding Certificate). It asks the IRS to approve reduced or zero withholding based on your expected actual tax, so far less is held in the first place. Once the buyer has already wired $97,500 to the IRS, that ship has sailed — your only route is the annual return. Plan the 8288-B at the listing stage, not at the closing table. (IRS — About Form 8288-B.)
The ~90-day refund window and how to track it
FIRPTA refund returns are not the fast electronic kind. They are paper-heavy nonresident returns with attachments (the stamped 8288-A, often an ITIN application), and the IRS processes them by hand. Plan on a meaningfully longer wait than a domestic e-filed refund.
| Stage | Typical timing |
|---|---|
| You file the 1040-NR with stamped 8288-A | Day 0 (once the tax year has ended) |
| IRS acknowledges / begins processing | Several weeks |
| Refund issued (clean return, stamped copy attached) | Roughly 90 days is a realistic baseline; longer if an ITIN is being issued in parallel |
How to track it: nonresident paper returns are not always visible in the standard online "Where's My Refund" tool. Your most reliable check is to call the IRS international taxpayer line and, once you have an ITIN, order an account transcript that shows the withholding posted and the refund status. Keep your stamped 8288-A and a copy of the full filed return — if the IRS opens correspondence, those documents resolve it. (IRS — International taxpayers.)
If a stamped 8288-A was missing or the buyer's reporting was incomplete, expect the timeline to stretch well past 90 days. The cleanest, fastest refunds are the ones where the ITIN was already in hand and the stamped 8288-A went into the envelope.
- FIRPTA withholding (typically 15% of the gross sale price) is a deposit, not your tax. Your real tax is based on your gain, which is usually a fraction of the price.
- You reclaim the excess by filing Form 1040-NR for the year of sale and attaching the stamped Copy B of Form 8288-A as proof of the withholding.
- Your refund size is set by how correctly you compute the gain: sale price − selling costs − adjusted basis (original cost + improvements − depreciation).
- You must wait until the tax year ends to file the return — there is no mid-year FIRPTA refund. To avoid over-withholding in the first place, file Form 8288-B before closing.
- Get an ITIN early — the IRS won't even release your stamped 8288-A without your TIN, and that's the #1 cause of stalled refunds.
- Budget around 90 days for a clean refund; longer if an ITIN or missing stamped copy is in play.
How long does a FIRPTA refund take on a 1040-NR?
For a clean return — stamped Copy B of Form 8288-A attached and an ITIN already issued — roughly 90 days is a realistic baseline. These are paper-processed nonresident returns, so they take longer than a domestic e-filed refund. If you are applying for an ITIN at the same time, or the stamped 8288-A is missing, expect the timeline to stretch beyond 90 days.
Why was 15% of my entire sale price withheld when my profit was tiny?
FIRPTA withholding is calculated on the gross "amount realized" (the sale price), not on your profit, because the buyer has no way to know your basis, improvements, or costs. The IRS holds against the worst case and refunds the excess once you file a return showing your actual gain and the small tax on it.
Do I really need the stamped Form 8288-A to claim the refund?
Yes. The IRS instructions state the transferor must generally attach the stamped Copy B of Form 8288-A to the U.S. income tax return to receive credit for the withholding. The IRS won't release that stamped copy if your TIN was missing from the form — so get your ITIN sorted, then make sure the stamped copy goes into your return.
Can I claim the FIRPTA refund before the end of the tax year?
No. The refund comes through your annual Form 1040-NR, which reconciles the whole tax year, so you can't file it until the year of sale has ended. If you want less withheld up front instead of waiting for a refund, file Form 8288-B (Application for Withholding Certificate) before or around closing to request reduced or zero withholding.
What counts as adjusted basis when I calculate the gain?
Adjusted basis is your original purchase price plus capital improvements (renovations, a new roof, additions) and certain acquisition costs, minus any depreciation you took or should have taken if it was a rental. Selling costs like the agent commission come off separately. Keep invoices and the closing statements — the IRS can request proof.
I rented the property out — does that change my refund?
Yes. Depreciation you claimed (or were entitled to claim) reduces your basis and is "recaptured" at a maximum 25% rate, which raises your true tax above a simple capital-gains estimate. Your refund will still likely be substantial, but smaller than for a never-rented property. Have a cross-border preparer run the depreciation recapture before you assume the full withholding comes back.
