US Estate Tax: Why the US-UK Treaty Is Uniquely Favorable
<FIRPTA and the US-UK Treaty
UK nationals who sell US property are subject to FIRPTA (15% withholding) unless they are US persons (green card holders, substantial presence qualifiers). The US-UK income tax treaty reduces withholding on rental income to a maximum of 15% (vs 30% for non-treaty countries). The treaty also provides: (1) Capital gains from US property are taxable in the US for UK sellers; the UK gives a foreign tax credit for the US tax paid. (2) Rental income from US property: treaty allows UK landlords to elect to be taxed on net income (after expenses) rather than gross rents. (3) No double withholding on dividends or interest from US entities holding UK investment property.
Rental Income Treatment Under the Treaty
British expats who buy US property while maintaining UK tax residency must report rental income on both their UK Self Assessment and US Form 1040NR. The US-UK treaty provides a foreign tax credit mechanism so the same income is not fully taxed in both countries. See: Rental Income Tax Guide for Foreign Property Owners.
UK Split-Year Treatment
British nationals who leave the UK during a tax year may qualify for UK 'split-year' treatment, dividing the year into a UK part and a non-UK part. This affects how rental income from US property is reported in both countries and is particularly relevant for Britons relocating to the US.
Ryan Brown, Principal Broker & CEO — Own Luxury Homes®
“I tell British buyers who are worried about US estate tax that they have a better deal than almost any other nationality. The US-UK treaty may provide the full unified credit, not the $60,000 that most countries get. That changes the entire ownership structure conversation. You may not need a complicated entity structure at all.”

Frequently Asked Questions
Does the US-UK tax treaty eliminate US estate tax for British nationals?
Not automatically, but the treaty may provide the full US unified credit ($13.61M) rather than the $60,000 that most non-US nationals receive. This requires proper election and filing. Consult a US-UK cross-border estate attorney.
Does the US-UK treaty reduce FIRPTA withholding for British sellers?
No. The treaty does not reduce the 15% FIRPTA withholding rate on property sales. However, it caps withholding on rental income at 15% (vs 30% for non-treaty countries).
Must British owners pay UK tax on US rental income?
Yes. UK tax residents report worldwide income to HMRC. The US-UK treaty foreign tax credit prevents double taxation by crediting US tax paid against UK tax on the same rental income.
