Introduction: Why FIRPTA Withholding Alarms Americans Selling From Abroad
FIRPTA withholding frightens more American sellers than almost any other rule in cross-border property tax, and most of that fear is misplaced. The Foreign Investment in Real Property Tax Act requires buyers to withhold fifteen per cent of the gross sale price when a foreign person sells United States real estate. Consequently, sellers instructing lawyers from London, Dubai or Singapore often assume the deduction is inevitable.
It usually is not. However, the exceptions are narrower than most people believe, and the traps sit exactly where wealthy families least expect them. Specifically, they sit with your spouse, your title deeds and your closing timetable.
This guide explains precisely when the rule bites, how much it costs, and how to stop cash being trapped with the Internal Revenue Service for eighteen months. Furthermore, it covers the British side of the same transaction, which advisers on the American side routinely overlook.

What FIRPTA Withholding Actually Is
FIRPTA withholding is a collection mechanism, not a tax. Congress enacted it in 1980 because foreign sellers could dispose of American property and leave the country before any return fell due. Therefore, the law shifts responsibility onto the buyer, who becomes a withholding agent under section 1445 of the Internal Revenue Code.
The buyer must deduct the statutory percentage and remit it to the Treasury within twenty days of closing. Additionally, they file Forms 8288 and 8288-A to report the payment. Failure exposes the buyer personally to the tax, plus interest and penalties, which explains why closing agents apply the rule so aggressively.
Importantly, the deduction is a credit against your eventual liability. Accordingly, over-withholding is a cash flow disaster rather than a permanent loss. Nevertheless, the cash flow disaster can run to seven figures.

Why Your Passport Matters More Than Your Address
Here is the point that saves most of our clients a great deal of money. FIRPTA applies only to foreign persons. Meanwhile, a United States citizen remains a US person for these purposes regardless of where they live, how long they have been away, or which other passports they hold.
Therefore, an American who has lived in Chelsea for twenty-five years and sells a Boston brownstone faces no federal withholding at all. Similarly, a green card holder who has kept lawful permanent resident status stands outside the regime. Residence abroad is irrelevant to the analysis.
You prove this with a certification of non-foreign status, commonly called a FIRPTA affidavit. Specifically, you sign a statement giving your name, address and taxpayer identification number, confirming under penalty of perjury that you are not a foreign person. Consequently, the closing agent releases the funds in full.

When the Fifteen Per Cent Applies and When It Does Not
The rate is not uniform, and the distinctions matter enormously on high-value sales. Furthermore, the calculation applies to the gross amount realised, not to your gain. That single feature causes most of the damage.
The Amount Realised Trap
Consider a property bought for $3 million and sold for $3.2 million. The gain is $200,000. However, FIRPTA withholding at fifteen per cent of the gross price produces a deduction of $480,000. Therefore, the withholding exceeds the entire profit by a factor of more than two.
Now add a mortgage. The amount realised includes debt discharged, so a leveraged seller can face withholding that exceeds their net proceeds entirely. In our experience, this scenario arrives at closing as a genuine emergency, because the seller has already committed the money elsewhere.
Accordingly, planning must happen weeks before completion, not on the day. We return to the mechanism for fixing this shortly.

The $300,000 Residence Exemption
An exemption removes withholding entirely where the price does not exceed $300,000 and the buyer intends to use the property as a residence. Specifically, the buyer or a family member must occupy it for at least half the days it is used during each of the first two twelve-month periods after transfer.
Notably, the test depends on the buyer's intention, not the seller's. Therefore, a corporate purchaser or an investor landlord destroys the exemption regardless of price. Additionally, the buyer must genuinely commit, because they carry the liability if the representation proves false.
For high-net-worth sellers this threshold rarely helps. However, it matters for former holiday homes and inherited family property in lower-cost states.
The Reduced Ten Per Cent Band
Between $300,001 and $1 million, the rate falls to ten per cent where the same residence condition applies. Above $1 million, fifteen per cent applies without exception. Consequently, most transactions our clients bring us sit squarely in the full-rate band.
Meanwhile, several states impose their own withholding on top. California deducts three and one-third per cent of the sale price under its own regime, reported on Form 593. Similarly, New York, Maryland, Hawaii and others operate parallel systems. Therefore, a Californian sale by a foreign person can suffer more than eighteen per cent in combined deductions.

The Non-US Spouse Problem
This is where sophisticated families get caught. Many of our clients married abroad, and their spouse holds no American status whatsoever. Consequently, one seller is exempt and the other is not.
Joint Ownership and Split Withholding
Where an American and a non-resident alien own property jointly, the rules apply to the foreign spouse's share alone. Therefore, the closing agent allocates the amount realised between the owners and withholds only against the non-US portion. On a fifty-fifty split of a $4 million sale, that produces $300,000 withheld rather than $600,000.
Allocation follows the actual ownership recorded on the deed. However, closing agents frequently apply the deduction to the entire proceeds when documentation looks unclear. Accordingly, you must supply a properly drafted allocation statement alongside your affidavit well before completion.
In one recent matter, a client avoided $310,000 of unnecessary deduction purely by producing the deed and a written allocation four weeks early. Preparation genuinely pays here.
Community Property and Title Complications
Community property states complicate the position further. In Texas, California, Arizona and six others, property acquired during marriage may be treated as owned half by each spouse irrespective of whose name appears on the deed. Therefore, an apparently sole American owner can discover that half the proceeds belong to a foreign person.
Similarly, holding structures create exposure. Property held through a foreign corporation or a non-grantor foreign trust makes the entity the seller, and entities are assessed on their own status. Consequently, an American beneficiary provides no protection at all.
We recommend reviewing title and structure at least three months before marketing. Restructuring after a buyer appears is rarely possible and frequently triggers separate consequences.

Getting an ITIN Before Closing
Every seller subject to FIRPTA withholding needs a taxpayer identification number. Without one, the buyer cannot properly report the deduction, and you cannot claim the credit. Furthermore, a non-US spouse typically has no number at all.
Applying takes time. Specifically, Form W-7 requires certified identity documentation and currently runs to several months in processing. Therefore, start the application as soon as a sale becomes likely, not once contracts exchange.
Certified acceptance agents in London can certify passports without you posting the original abroad. That single step removes the most common cause of delay we encounter.

Reducing the Withholding Before Completion
The statute contains a valuable release valve, and remarkably few sellers use it. Additionally, using it well can convert a six-figure cash trap into a modest deduction.
Form 8288-B Withholding Certificates
You may apply to the IRS for a withholding certificate reducing the deduction to your expected actual liability. Specifically, Form 8288-B sets out the calculation: sale price, adjusted basis, improvements, selling costs and the resulting gain. Therefore, a seller with a $200,000 gain on a $3.2 million property can seek withholding of roughly $40,000 rather than $480,000.
The IRS aims to respond within ninety days. Meanwhile, where the application is filed on or before the closing date, the buyer holds the funds in escrow rather than remitting them. Consequently, the money stays within reach and settles quickly once the certificate arrives.
This is the single most valuable step available. Nevertheless, it demands accurate basis records, which brings us to preparation.
What the Service Wants to See
Applications fail on evidence, not on principle. Therefore, assemble the original purchase settlement statement, invoices for capital improvements, and the depreciation schedules from every year the property was let. Additionally, include the draft contract and a clear computation.
Estimates will not do. In particular, an unsupported improvement figure invites rejection, and rejection costs you the escrow protection entirely.
We typically begin this file when a client first mentions selling. Consequently, the paperwork is ready when the buyer appears rather than assembled in panic.

Calculating the Real Tax on the Sale
Withholding is only ever a deposit. Ultimately, your liability depends on gain, holding period, prior depreciation and your residence position on both sides of the Atlantic.
Section 121 and the Two-of-Five-Year Rule
The principal residence exclusion removes $250,000 of gain, or $500,000 for a married couple filing jointly. However, you must have owned and occupied the property as your main home for two of the five years before sale. Therefore, Americans who moved abroad several years ago have usually lost it.
Timing occasionally rescues the position. For instance, a client who relocated to London in 2024 and sells before the fifth anniversary of departure may still qualify. Accordingly, we review the occupancy calendar before anything is marketed.
Note also that a non-resident alien spouse filing separately cannot use the joint $500,000 figure. Consequently, mixed-status couples should model both filing positions carefully.
https://www.irs.gov/taxtopics/tc701
Depreciation Recapture at Twenty-Five Per Cent
If you let the property, you claimed depreciation, and the IRS taxes that benefit back on sale. Specifically, unrecaptured section 1250 gain suffers a maximum federal rate of twenty-five per cent, ahead of the ordinary long-term capital gains rates.
Critically, recapture applies to depreciation allowed or allowable. Therefore, a landlord who never claimed the deduction still faces the charge. This catches accidental landlords constantly, particularly those who let a home informally after moving abroad.
Long-term gains above that layer attract zero, fifteen or twenty per cent federally. Additionally, American citizens face the net investment income tax at three point eight per cent, although non-resident aliens do not.

The British Side of the Same Sale
If you are resident in the United Kingdom, HMRC taxes the same gain. Furthermore, it computes the gain in sterling using exchange rates at acquisition and disposal, which can manufacture a British gain where no dollar gain exists.
Rates run to twenty-four per cent on residential property for higher-rate taxpayers. Meanwhile, private residence relief follows entirely different rules from section 121. Therefore, the two systems rarely produce matching answers.
Relief comes through the treaty and the foreign tax credit rules. Accordingly, sequencing the filings correctly matters, because claiming credit in the wrong direction wastes it permanently.

Case Study: A $2.4 Million Manhattan Sale
A client of ours, an American technology founder, moved to London in 2019 and kept his Tribeca apartment as a let property. He married a British national in 2021 and added her to the deed. Subsequently, he decided to sell in 2025 for $2.4 million.
The closing agent initially proposed deducting $180,000, applying fifteen per cent to his wife's half share. Additionally, the couple faced a genuine liability well below that figure. His basis stood at $1.75 million, improvements added $210,000, and selling costs came to $144,000. Therefore, the true gain was approximately $296,000, of which $128,000 represented depreciation recapture.
We filed Form 8288-B before closing, supported by six years of depreciation schedules and improvement invoices. Consequently, the IRS certified withholding of $29,500 against the wife's share rather than $180,000. Meanwhile, the founder himself provided a non-foreign affidavit and suffered no deduction whatsoever.
The combined federal charge settled at roughly $71,000 across both spouses. Furthermore, UK tax of £39,000 arose on his half, largely relieved by credit for the American tax. Ultimately, preparation released $150,000 of cash at completion that would otherwise have sat with the Treasury until late 2026.
Reclaiming Over-Withheld Tax
Where the deduction has already happened, recovery is procedural rather than difficult. However, it is slow, and the slowness is the cost.
Form 8288-A and Your Credit
The buyer files Form 8288-A and the IRS returns a stamped copy to you. Specifically, that stamped copy evidences your credit, and without it the Service will not process a refund. Therefore, chase the closing agent immediately if it does not arrive.
Attach it to your return for the year of sale. A non-resident spouse files Form 1040-NR, while the American files the ordinary Form 1040. Consequently, mixed-status couples often file two separate returns for a single transaction.
Refund Timelines and Cash Planning
Refunds of over-withheld amounts typically take between six and twelve months from filing. Additionally, a sale completing in March cannot be reported until the following filing season. Therefore, money withheld in early 2026 may not return until late 2027.
Interest does accrue in the taxpayer's favour in some circumstances. Nevertheless, the rate rarely compensates for the opportunity cost on a seven-figure sum. Accordingly, prevention through a withholding certificate always beats recovery.

Conclusion
FIRPTA withholding rarely applies to Americans selling their own American property, however long they have lived abroad. Your citizenship protects you, and a simple affidavit proves it. Therefore, the anxiety most sellers carry into the process is unnecessary.
The genuine risks lie elsewhere. Specifically, they lie with a non-US spouse on the deed, with community property rules, with holding structures, and with the gross-price basis of the calculation. Additionally, they lie in the gap between what you owe and what gets deducted.
Preparation resolves all of them. Accordingly, start at least three months before marketing, secure identification numbers early, and apply for a withholding certificate where any deduction will arise. Ultimately, the difference between good and poor planning on a substantial sale is measured in hundreds of thousands of dollars of trapped cash.
