US Expat Tax
US tax for Americans in the UK and abroad
US citizens and green card holders must file a US federal tax return on worldwide income wherever they live, and often an FBAR for foreign accounts over $10,000. Reliefs like the FEIE, Foreign Tax Credit and the US–UK treaty prevent double taxation — when claimed correctly. We handle it all, coordinated with your UK filings.
Being American doesn’t stop at the border. The US taxes its citizens on their worldwide income, so whether you moved to London last year or have lived in the UK for a decade, you still have annual US filing obligations — returns, and often foreign-account reporting on top.
We specialise in getting this right for people who live between two systems. That means claiming the correct reliefs, filing FBAR and FATCA where required, and coordinating with your UK Self Assessment so the two returns agree and you don’t pay tax twice on the same pound or dollar.

Frequently asked questions
Yes. The US taxes its citizens on worldwide income regardless of where they live, so Americans in the UK must file a US federal return every year — even if they owe nothing after reliefs like the Foreign Earned Income Exclusion or Foreign Tax Credit. Many also have to file an FBAR.
FBAR (FinCEN Form 114) reports foreign bank accounts when their combined value tops $10,000 at any point in the year. FATCA (Form 8938) reports foreign financial assets above higher thresholds and is filed with your tax return. Many expats must file both.
Usually not, if it is handled correctly. The Foreign Tax Credit, the Foreign Earned Income Exclusion and the US–UK tax treaty exist to prevent double taxation. The key is claiming the right relief in the right order — which is exactly what coordinated US–UK advice ensures.
If your failure to file was non-willful, the IRS Streamlined Filing Compliance Procedures let you catch up — typically three years of returns and six years of FBARs — without penalties. We handle Streamlined cases regularly and can bring you back into compliance.
