Both the US and UK tax the same capital gain — the US-UK double taxation convention reduces but doesn’t eliminate the overlap
US-UK Treaty
The US-UK Double Taxation Convention coordinates tax treatment of UK sellers’ US property gains
US and UK tax rules change. This guide is for educational purposes only. Consult a US tax attorney and a UK tax adviser with cross-border expertise.
When a British citizen sells US property, two countries want their share of the gain. The US collects FIRPTA withholding at 15% of the full sale price at closing. The UK taxes the same capital gain through its capital gains tax system. The US-UK Double Taxation Convention coordinates the two systems to prevent genuine double taxation, but “not double taxed” is different from “not taxed heavily.” Understanding both sides before listing is essential.

FIRPTA Withholding for British Sellers
FIRPTA applies to all non-US persons selling US real property. UK citizenship does not provide any exemption or reduction. The 15% withholding is calculated on the gross sale price: Example: A British citizen sells a Florida vacation home for $450,000. Original purchase price: $280,000. Gain: $170,000. FIRPTA withholds: 15% of $450,000 = $67,500. Actual US capital gains tax at 15% on $170,000 gain: $25,500. The $42,000 difference is recovered through Form 1040-NR or — ideally — through a Form 8288-B withholding certificate filed before closing. Full FIRPTA guide: FIRPTA complete guide.
The Form 8288-B Certificate: Apply Early
The withholding certificate allows the seller to reduce FIRPTA withholding at closing to the actual estimated tax rather than 15% of gross. For UK sellers: (1) Apply as soon as the property is listed or under contract. (2) IRS processing: typically 90+ days. (3) The withheld amount is placed in escrow at closing. (4) Once the IRS approves, the excess is released to the seller. On the $450,000 example: the certificate saves $42,000 released at closing rather than waiting for the annual US tax return refund.

The UK Side: Capital Gains Tax on US Property
UK residents who sell US property must also report the gain to HMRC. Key points for British sellers: (1) UK CGT applies: the same gain (converted to GBP at the transaction date exchange rates) is reported on the UK self-assessment tax return. (2) The UK annual CGT exemption: each individual has a UK annual CGT exemption (the amount changes with legislation — confirm the current allowance with a UK tax adviser). (3) UK CGT rates for residential property: currently 18% for basic rate taxpayers and 24% for higher/additional rate taxpayers on residential property gains (rates are subject to change). (4) The foreign tax credit: US capital gains tax paid is credited against the UK CGT on the same gain. If the US rate exceeds the UK rate, the UK CGT bill may be zero. If the UK rate exceeds the US, you pay the difference to HMRC. (5) Reporting deadline: the UK self-assessment return is due 31 January following the tax year end. The gain is reported in the UK tax year when the sale completes.
Remote Sale: Selling From the UK
UK sellers of US property rarely need to travel to the US to close. The remote selling protocol: (1) Virtual property assessment with US specialist. (2) Remote pricing and marketing approval. (3) Remote offer acceptance via digital signature. (4) Closing documents signed in the UK via e-notary or international courier. (5) Net proceeds wired to UK bank account after FIRPTA compliance. Convert USD proceeds to GBP through a currency broker, not your UK bank. Currency guide: GBP/USD currency strategy.
Ryan Brown, Principal Broker & CEO Own Luxury Homes®
"The British seller who calls me about their Florida condo is usually most worried about the US side: FIRPTA, the process, the timeline. What they haven’t thought about is the HMRC side: the same gain also goes on their UK self-assessment. The US tax credit reduces the UK bill in many cases. But the coordination between the 1040-NR deadline and the UK self-assessment deadline requires a cross-border adviser, not just a US specialist. I connect both."

Frequently Asked Questions
What is FIRPTA for UK sellers of US property?
A US withholding requirement: the buyer withholds 15% of the gross sale price from the British seller's proceeds at closing. Form 8288-B certificate reduces this to the actual capital gains tax on the gain.
Does the UK also tax the gain when a British citizen sells US property?
Yes. The same capital gain (in GBP) is reported on the UK self-assessment. US capital gains tax paid is credited against UK CGT. If US tax exceeds UK tax, UK CGT may be zero. If UK rate is higher, you pay the difference to HMRC.
Is there a US-UK double taxation treaty for property sales?
Yes. The US-UK Double Taxation Convention coordinates taxation of property gains. It prevents genuine double taxation but both countries still tax the gain — the treaty provides credit mechanisms so you pay the higher of the two rates, not both in full.
How does a British seller coordinate the US and UK tax deadlines?
US Form 1040-NR: due June 15 (automatic) for non-resident aliens, October 15 with extension. UK self-assessment: 31 January following the tax year end. Both returns need the same gain data. A cross-border tax adviser coordinates.
