US + UK tax, made human

Two tax systems.
One clear view.

If you are American and living in Britain, you file in both countries every year. We prepare both returns from one office in Edinburgh, so nobody has to translate between your accountants.

The bridge between both returns

One practice.
Two jurisdictions.

Move between the IRS and HMRC sides to see how one connected view changes the advice.

The ClearTaxation method

One picture.
Five useful moves.

As your position changes, the advice changes with it. We keep both countries in view at every stage.

01

Understand the whole position

Income, investments, property and citizenship, assembled before advice begins.

02

Separate the two rulebooks

We identify what the IRS sees, what HMRC sees, and where the treaty connects them.

03

Align the filings

One set of figures, carried carefully through the US and UK returns.

04

Make the next decision clearer

Know what to hold, report or change before the next deadline arrives.

05

Stay ready for the year ahead

A practical plan that makes the next conversation shorter and calmer.

The points of friction

Where the two systems disagree.

Most of the trouble we fix started with advice that was perfectly correct — for someone who wasn't American.

What you haveThe IRS viewThe HMRC view
Stocks & shares ISAA passive foreign investment company. Form 8621, punitive rates.Entirely tax free.
UK workplace pensionGrowth may be taxable unless you claim the treaty position.Relief at source, no tax until you draw it.
Selling the family homeGain above the exclusion is taxable, plus currency movement on the mortgage.Usually no capital gains tax at all.
A joint account with a British spouseReportable on the FBAR once the balance passes the threshold.Of no interest whatsoever.
A limited company you set up hereA controlled foreign corporation. Form 5471 and a GILTI calculation.A normal small company filing normal accounts.

People we help

Where people usually
find us.

Four situations account for most of the Americans who get in touch. If yours isn't here, it is probably still familiar.

01

You've just moved
to the UK

Your first year is the one that sets everything up: split-year treatment, which country taxes what, and what to do before you open a single UK account.

Explore situation
02

You've been here
for years

You are far from alone. The IRS has a route back that carries no penalty for people who genuinely didn't know. We handle the whole submission.

Explore situation
03

Your investments
are a problem

ISAs, UK funds, offshore bonds and some pensions carry reporting the IRS treats harshly. We work out what you actually hold.

Explore situation
04

You're thinking about
giving up citizenship

Renunciation has a tax exit as well as an appointment at the consulate. We model what it would cost and whether the filings are in place.

A useful starting point

place to begin.

Why Cleartaxation

Qualified on both sides,
not one side each.

Most firms serving Americans in Britain are American firms with a UK contact, or UK firms with a US contact. Your two returns get prepared by two people who email each other.

We hold both qualifications in the same practice: Chartered Tax Adviser for the UK side and IRS Enrolled Agent for the US side. One person sees the whole picture.

The difference

A better way to hold
both sides together.

01

You are in our time zone

Calls at a civilised hour, and an office at 93 George Street if you would rather sit down with someone.

02

One adviser, not a queue

You deal with the person doing the work. No ticket system, no reassignment each season.

03

Both returns, one set of figures

The UK self assessment and the US 1040 are prepared together from the same information you send once.

04

Planning, not just filing

Investment and pension advice sits in the group, so the answer to “what should I hold instead?” doesn't stop at “ask someone else”.

A calm process

Four steps to feeling
properly looked after.

One conversation. One document request. Both countries understood.

  1. 01

    A 15-minute call

    Free, and enough to tell you whether you have a real problem or a straightforward year.

  2. 02

    A fixed quote

    You get the price and the list of forms in writing before anything starts.

  3. 03

    One document request

    A single secure upload covering both countries, tailored to what you actually hold.

  4. 04

    Both returns filed

    We prepare, you review, we file — and tell you what to change before next year.

Straightforward fees

What it costs.

Fixed fees, agreed before work begins. Complex holdings add forms, and we tell you which ones and what they cost at the quote stage.
