US-UK Cross-Border Tax
US Tax Specialists for Americans in the UK
US tax specialists who prepare your American return and your UK Self Assessment as one position — so you claim every credit, stay compliant with the IRS and HMRC, and never pay tax twice.
If you are a US citizen or green card holder living in Britain, you file with both the IRS and HMRC every year. Getting that right takes US tax specialists who understand both systems at once — not a UK accountant who stops at your Self Assessment, and not a US preparer who has never seen a P60.
TaxYork prepares your federal Form 1040, your FBAR and FATCA disclosures, and your UK return together. We apply the Foreign Tax Credit and the Foreign Earned Income Exclusion correctly, handle PFIC reporting on UK funds and ISAs, and take treaty positions where they save you money — so your two returns agree and your worldwide tax bill is as low as the rules allow.
Behind on filing? We bring Americans back into compliance through the IRS Streamlined programme, usually penalty-free. Already compliant? We make sure it stays that way, year after year.

Frequently asked questions
What does a US tax specialist do for Americans in the UK?
A US tax specialist prepares and files your US federal return, FBAR and FATCA forms while coordinating them with your UK Self Assessment. The aim is a single, correct cross-border position — claiming the Foreign Tax Credit or Foreign Earned Income Exclusion so you are not taxed twice, and keeping you compliant with both the IRS and HMRC.
Why use a US tax specialist instead of a regular accountant?
US citizens are taxed on worldwide income wherever they live, so a UK-only accountant will miss FBAR, FATCA (Form 8938), PFIC reporting on UK funds, and treaty positions. A US tax specialist handles both systems together, which is what prevents double taxation and IRS penalties.
Can US tax specialists help if I have not filed in years?
Yes. Most Americans who fall behind qualify for the IRS Streamlined Foreign Offshore Procedures, which bring you up to date with three years of returns and six years of FBARs and typically waive all penalties for non-wilful non-compliance.
Do you handle both my US and UK tax returns?
Yes. TaxYork prepares your US federal return and your UK Self Assessment as one connected position, so credits, timing and elections line up across both countries rather than being filed in isolation.
How much do US tax specialists charge?
Fees depend on the complexity of your income and foreign accounts, but we quote a fixed price up front after a short review of your situation, so there are no surprises. Book a consultation and we will give you a clear number.
Do you work with US expats outside the UK?
Our focus is the US-UK corridor, where cross-border rules are most complex, but we advise US citizens across several countries. The fastest way to check is a short consultation.
