US & UK Tax Specialists.
Two Systems. One Position.
US and UK filings prepared together — from first return to final treaty claim.
Living across the US and UK means answering to two tax authorities. We prepare both sides as one coherent position — never as two disconnected returns.
US UK Tax Accountants is a cross-border practice for Americans in the UK, Brits in the US and everyone in between. Senior specialists on every file, fixed fees agreed in writing before any work begins, and replies within a business day.
Cross-Border Tax Services.
Work with US UK tax specialists on the advisory side, or US UK accountants for both annual returns prepared together.
Every engagement starts with a fixed fee, agreed in writing before any work begins.All services & form guides →

Client Testimonials.
They picked up five years of unfiled returns and took me through the Streamlined programme without a single penalty. The relief was enormous.

Crossing Borders.
Remote work, dual careers and transatlantic families have made cross-border lives ordinary. The US and UK tax systems, though, were never designed to talk to each other.
We prepare both sides of the Atlantic as one position — relief claimed once, credits landing where they should, and nothing reported twice.
What We Do.
Every Cross-Border Situation, Covered
Five practice areas, one team, and a single position across both tax systems — with a fixed fee agreed in writing before any work begins.
All Services01
Tax Planning & Advisory
Elections, treaty positions and timing modelled before you commit — not repaired after.
02

Form 1040 and Self Assessment prepared together by one team, as one position.
03

One property, two tax returns. Sales, rentals and gains handled on both sides.
04
Pensions & Investments
ISAs, PFICs, 401(k)s and SIPPs reported correctly and structured to stay that way.
05
Compliance & Disclosure
FBAR, FATCA and streamlined catch-up filing, penalty-free where the programmes allow.
Cross-Border Tax.
One Coherent Position
We take ownership of both filings — from document collection and elections through to submission on each side of the Atlantic.
Where you owe filings on both sides, we do not finish one and then start the other. Figures and timing on the UK return feed directly into the credits claimable on the US side, and the order matters to the final number. A senior specialist models both routes — exclusion or credit, remittance or arising — before anything is filed.
How It Works.
Our aim is to make filing in two countries feel like filing in one
Email Consultation
A free exchange by email about what you hold. Scope and a fixed fee follow in writing within 24 hours.
Onboarding
Documents uploaded once through a secure portal, mapped to both returns from the start.
Preparation
One team prepares the US and UK filings together, modelling elections on both sides.
Review & Approval
Walk through both returns with your specialist before anything is submitted.
Filing & Beyond
We file with the IRS and HMRC, confirm acceptance, and stay on hand all year.
A Year-Round Tax Partner
Cross-border tax is not a January event. Elections made this year echo for five, residence positions shift, and a move home changes everything. The same senior specialist stays on your file year after year — so you never re-explain your situation, and the judgement calls made in year one are remembered in year three by the person who made them.
They understand both systems deeply enough to make them agree with each other. I would recommend them to anyone with a foot on each side of the Atlantic.
