Americans in the UK
Coordinated US and UK tax filing for American expats. One team on both sides of the Atlantic handles your federal returns, Self Assessment, FBAR, and treaty relief.
Two returns, one plan.
Living in the UK doesn't end your US tax obligations. It doubles them. Every American in the UK must keep filing US returns on worldwide income while also meeting HMRC's requirements. We prepare both sides together, so treaty relief, foreign tax credits, and elections all line up.
From your first year abroad to permanent settlement, we handle the annual mechanics and the long-term planning: pensions, property, investments, and eventual moves home.
How we help Americans in the UK
Complete US and UK tax compliance and planning, coordinated under one roof.
US Federal Tax Returns
Annual Form 1040 preparation with the expat mechanisms applied correctly: Foreign Earned Income Exclusion, Foreign Tax Credit, and treaty positions coordinated with your UK filings.
UK Self Assessment
We prepare your UK Self Assessment alongside your US return so the two filings agree. That includes remittance basis analysis, residence status, and split-year treatment.
FBAR & FATCA Reporting
FinCEN Form 114 and Form 8938 for your UK bank accounts, ISAs, and pensions. We track the thresholds across both forms so nothing goes unreported.
PFIC Analysis & Form 8621
UK funds, ISAs, and investment platforms are frequently PFICs under US rules. We identify your exposure, prepare Form 8621, and restructure holdings so the punitive treatment stops.
UK Pension Planning
Workplace pensions, SIPPs, and lump sums each get different US treatment. We apply the US/UK treaty correctly so your retirement savings aren't taxed twice.
Streamlined Catch-Up Filing
Behind on US filings? The Streamlined Foreign Offshore Procedures let most Americans abroad catch up without penalties. We manage the whole submission for you.
One team prepares your US and UK filings properly, for a fixed fee.
Get StartedExplore our tax services
Built for lives lived in two countries.
The worst cross-border outcomes come from advisers who only see half the picture. Our US and UK teams work the same file, so relief is claimed in the right country and the right year, every time.
Paying tax twice is a preparation failure.
Between the treaty, the Foreign Tax Credit, and the Foreign Earned Income Exclusion, almost no American in the UK should suffer true double taxation. When it happens, it's because two disconnected preparers each optimized their own half. We plan across both returns at once.
Foreign Tax Credit Strategy
UK tax rates usually exceed US rates, so a properly claimed credit for UK tax wipes out the US bill. We work the credit basket by basket.
FEIE vs. FTC Modeling
The exclusion isn't always the right answer. We model both routes every year and pick the one that saves more, including the effect on IRA eligibility and child tax credits.
Currency & Timing Positions
Every UK transaction must be translated to dollars at the right rate. We apply consistent, defensible FX methodology across income, gains, and mortgage events.
State Tax Exit Support
California and other sticky states don't let go easily. We document your state residency break so your old state doesn't keep taxing you from 5,000 miles away.
Why Americans in the UK choose US/UK Cross Border Tax
Both Sides, One Team
US CPAs and UK tax advisers work on the same file, so you don't get conflicting advice or gaps between preparers who never compare notes.
Treaty Fluency
The US/UK tax treaty is our daily working document. We apply its rules on pensions, savings clauses, tie-breakers, and resourcing with precision.
Deadline Choreography
US and UK tax years don't align. We sequence both filings so credits land in the right year and you never pay twice or late.
Fixed, Transparent Pricing
Cross-border filing shouldn't mean open-ended hourly billing. We give you a fixed quote up front that covers both jurisdictions.
"I'd been filing US returns myself for years and had no idea my ISA was a problem. They restructured everything, caught me up through streamlined, and now both returns are done together every spring."
