One life in the UK. Two tax returns that agree.
You're a US citizen or green-card holder living in the UK. The US taxes you on worldwide income wherever you live; the UK taxes you as a resident. Two returns, two authorities — and, filed separately, a real risk of paying tax twice on the same money.
Why two accountants isn't enough
Your UK accountant files self-assessment but can't touch your 1040. A US preparer handles the 1040 but doesn't know how your UK income, pension or ISA should sit on it. The treaty and foreign tax credits only work when someone owns both sides and sequences them in the right order. That gap — between two local accountants — is exactly what we close.
Both sides, under one roof
Three steps, one team
Position review
We map your income, accounts and assets across both systems and spot anything that clashes before it becomes a problem.
Sequenced filing
We prepare both returns together, in the order that makes the credits and treaty positions line up — never one in isolation.
Kept in step
One team, one calendar, fixed fee. You approve, we file, and the two sides always agree.
The things people ask first
Do I really have to file a US return if I already pay UK tax?
Yes — the US taxes citizens and green-card holders on worldwide income, wherever they live. UK tax you've paid usually offsets the US bill through foreign tax credits, but the return itself is still required.
What about my ISA or UK pension?
They aren't automatically tax-free from the US side, and some UK funds create extra US reporting. We handle how each one is treated so there are no surprises.
I'm behind on my US filings — is that a problem?
It's fixable. Where you qualify, the Streamlined procedures bring you back into compliance without penalties. We'll tell you honestly where you stand first.
Let's map your two sides.
A free consultation, no obligation. We'll look at your US and UK position together and tell you exactly what you need — and what it costs, up front.
