US UK Tax Experts: Helping Americans and UK Residents Navigate Cross-Border Taxation
What US UK Tax Experts does, who it is for, and how one team prepares the US and UK returns from the same file.

Written by the US UK Tax Experts team, cross-border tax specialists
What does US UK Tax Experts do?
US UK Tax Experts prepares and files US and UK tax returns for people and businesses with obligations in both countries. The work is preparation, filing and compliance: returns, foreign account reports, treaty claims and the company filings that sit between the IRS and HMRC.
Who is it for?
- Americans living in the UK, who have to file a US return every year as well as dealing with HMRC.
- UK residents with US income, such as rent from a US property, US dividends or a US pension.
- Dual citizens and green card holders, including people who have never filed a US return and need to catch up.
- Businesses operating in both countries, with a US shareholder in a UK company, or a company on each side.
- Trustees, executors and beneficiaries where a trust or estate has a US connection.
Why use one team for both countries?
Because relief claimed in one country depends on what was filed in the other. A foreign tax credit on the US return has to match the tax shown on the UK return, and a treaty claim made to HMRC has to be consistent with the position taken at the IRS. Most double taxation comes from two preparers who never see each other's work.
What do you prepare?
- US federal and state returns, including Form 1040 and the schedules that go with it.
- UK Self Assessment returns, coordinated with the US filing.
- FBAR and FATCA reporting for foreign accounts and assets.
- PFIC reporting on Form 8621 for UK funds and investment trusts.
- Treaty relief claims and foreign tax credits on both sides.
- Streamlined filing for people who have missed years.
- Company filings, including Form 5471 and UK corporation tax returns.
How does an engagement run?
- Review: we look at both sides together, including what has already been filed or missed.
- Position: we set out the treaty position and the reliefs that apply, with the numbers behind each option.
- File: we prepare and submit to the IRS and HMRC, keeping the two sets of filings consistent.
- Keep current: two tax calendars mean deadlines all year. We track them and tell you before they arrive.
