One team, both tax systems
US-UK Accountants for Cross-Border Americans
US-UK accountants who prepare your Form 1040 and your UK Self Assessment together — one team, one coordinated position, no double taxation and no missed filings.
Most accountants work in one country. If you are American and living in Britain, that is the problem: you owe returns to both the IRS and HMRC, and figures prepared in isolation rarely agree. US-UK accountants prepare both sides together, so your credits, exchange rates and timing match.
TaxYork files your US federal return, FBAR and FATCA disclosures alongside your UK Self Assessment. We apply the Foreign Tax Credit so tax paid to HMRC offsets your US bill, take treaty positions on pensions and investments, and handle the reporting that trips up American company owners and investors in the UK.
Whether you are employed, self-employed, a landlord or a company director, one team owns the whole picture — and quotes you a fixed fee before any work begins.

Frequently asked questions
What are US-UK accountants?
US-UK accountants prepare both American and British tax returns for the same client. For a US citizen living in Britain that means Form 1040, FBAR and FATCA on the US side and Self Assessment on the UK side, filed as one coordinated position so credits and timing match across both countries.
Do I need US-UK accountants or just a UK accountant?
If you are a US citizen or green card holder, a UK-only accountant cannot file your US return and will miss FBAR, FATCA and PFIC reporting on UK funds. US-UK accountants handle both systems, which is what keeps you compliant with the IRS and HMRC at the same time.
Can US-UK accountants file both returns together?
Yes — that is the point. When one team prepares both returns, the Foreign Tax Credit, exchange rates, pension treatment and treaty positions all line up, instead of two separate accountants producing figures that conflict.
Do US-UK accountants handle self-employed and company owners?
Yes. We prepare UK Self Assessment and US Schedule C or company filings, and we handle the extra US forms that catch owners out, such as Form 5471 for a controlled foreign company and the GILTI rules.
How do US-UK accountants stop me being taxed twice?
By applying the US-UK tax treaty and the Foreign Tax Credit correctly. Tax paid in one country is generally credited against the other, and specific treaty articles decide which country taxes pensions, dividends and gains first.
What does it cost to use US-UK accountants?
We quote a fixed fee up front once we understand your income and accounts, so you know the cost before any work starts. Book a short consultation for a clear number.
