Cross-border life.
Clear US tax answers.
Pick your situation below. Every audience page lists the filings that typically apply, the traps to watch for, and what we do for clients like you — whichever side of the Atlantic you're on.
Two tax systems, one filing relationship.
Most of our clients have a foot in both countries — by birth, by employer, by marriage, or by accident of timing. The paperwork doesn’t care which. Whether you’re an American who moved to London ten years ago or a British executive on a two-year posting in New York, the same handful of US filings need to read correctly to the IRS and reconcile cleanly with HMRC. We do that work for a living.
The audience pages below are a starting point — pick the one that sounds closest to you, and the filings, traps, and fees that typically apply will be there.
Six common starting points.
These cover roughly nine in ten of the people who come to us. If your situation is a hybrid — most are — start with the closest match and we’ll fork from there.
- Audience
Americans in the UK
You're a US citizen or Green Card holder living in the UK. You owe the IRS a return every year — and probably an FBAR — even though all your income is taxed in the UK.

AudienceBritish people in the US
You're a UK national who has moved to, or regularly does business in, the US. You may face US filing obligations alongside your UK ones — and UK pensions, ISAs, and property need to be reported or planned for.

AudienceDual US-UK citizens
Dual citizens file on both sides — every year, regardless of where you live. The good news: the US-UK treaty and foreign tax credits usually eliminate double tax. The work is in doing it right.

AudienceGreen Card holders
A Green Card keeps you 'in the US tax net' for the IRS — even when you live permanently in the UK. Long-term Green Card holders who eventually give up status may also face exit tax.

AudiencePre-immigration movers
Moving to the US soon? The window before you become a US tax resident is the best time to restructure investments, realise gains, and document basis. After arrival, the planning options narrow sharply.
See how we help
AudienceNon-resident aliens
You're not a US person, but you have US-source income — rental property, royalties, business income, or a US-tax-withholding problem. A 1040NR may be required, and the treaty can help.

Three steps from first email to filed return.
Whatever audience you fall into, the engagement shape is the same. Below is what you can expect — and where the fixed-fee quote arrives in the timeline.
01Tell us your situation
A short note via Get Started or a 20-minute scoping call. We confirm which filings apply and what we’d want to see. No commitment yet.
02Written fee quote
A scope document and fixed fee back to you within 2 working days. Nothing starts until you confirm — no open-ended billing, no surprises.
03Prepare, review, file
Drafted by ACCA staff, second-reviewed by an Enrolled Agent, e-filed with the IRS / FinCEN. Plain-English commentary on every position taken on your return.
- 20+ yrsof cross-border practice
- 2qualifications — ACCA + Enrolled Agent
- Fixedfees, agreed before any work begins
- 48 hrstypical response on weekdays
The same six questions, every time.
Before we build a fee quote, we work through the items below. Most are settled in a single intake call — a few need documentation. Either way, the scope is on the table before you commit.
- Filing the right return for your residency status — 1040, 1040NR, or a dual-status return
- Choosing FEIE vs. Foreign Tax Credit on the actual numbers, not a rule of thumb
- FBAR and Form 8938 disclosure on UK accounts and joint accounts above threshold
- PFIC exposure on ISAs, OEICs, unit trusts, and most non-US funds
- Treaty positions disclosed on Form 8833 where they actually save tax
- Pension reporting — SIPPs, workplace, and US 401(k) / IRA — without double counting
We won’t take you on if cross-border isn’t the edge of your case.
We don’t prepare US-domestic-only returns. We don’t do bookkeeping. We don’t take on tax planning that doesn’t involve at least one foreign element. The narrower the practice, the better the work — and we’d rather refer you to the right place than stretch ours.
- Single-jurisdiction US tax (no foreign element)
- Bookkeeping or general accounting services
- UK-only HMRC returns without a US dimension
- Anything where the cross-border line is the work

A short note about where you live, where your income comes from, and where the IRS thinks you live is enough for us to come back with a clear next step.
