US–UK tax advisors, prepared together
Two tax systems. One set of figures.
Tax returns for Americans in the UK, without the double handling. We prepare US federal returns, FBAR and FATCA reports, IRS Streamlined submissions and UK Self Assessment from one set of figures, so what is filed in one country matches what is filed in the other.
- Email-first, so every figure and decision is documented.
- Written fee agreed before any work starts.
- Every return reviewed by a second person.

What we prepare
Compliance work first. Advisory when it is actually needed.

FAQ
Questions we are asked
Do I have to file a US tax return if I live in the UK?
Yes, if you are a US citizen or green card holder with income above the filing threshold. The US taxes on citizenship. Paying UK tax usually reduces or removes what you owe, but the return still has to be filed.
How do you work?
By email and through your client portal. You send a short enquiry, we reply within two working days with what is needed and a written fee, and nothing starts before you have agreed it. We do not offer free consultations; paid 20-minute consultations are available where a conversation is genuinely needed.
What does it cost?
Fees depend on the returns, forms and years involved, so we quote only once we know all your sources of income and your filing history. The quote is in writing and is the fee you pay, unless the facts change.
Can you deal with the IRS or HMRC for me?
We prepare and file returns, amendments and the figures needed to respond to a notice. Correspondence with the tax authorities stays in your name; we do not act as your representative.
Do you give investment advice?
No. We explain the tax consequences of your options. We are not FCA-regulated and the investment decision stays with you or your financial adviser.
