Who we help

Cross-border tax filing for individuals and families

Expatriates, dual citizens, and families with international ties need specialist tax preparation. We help individuals and families meet their tax obligations across the US and UK, from income reporting to investment taxation.

Tax Solutions for Individuals & Families

Managing personal tax obligations across the US and UK is complex. Expatriates and dual citizens face unique challenges including foreign income reporting, double taxation issues, and compliance with strict reporting requirements like FATCA and FBAR.

We help individuals and families understand their tax obligations in both countries, file accurate returns with all required forms, and claim the foreign tax credits, exclusions and treaty relief that stop the same income being taxed twice. Whether you're moving between countries, managing international income, or simply trying to understand your obligations, we're here to help.

Our team gives you clear, personal answers about what you need to file, ensuring peace of mind and allowing you to focus on life and family while we handle your tax returns in both the United States and the United Kingdom.

How an engagement runs

Two authorities, one file. Here is what working together actually looks like.

  1. Review

    We look at both sides together: what you file, where, and what has already been filed or missed.

  2. Position

    We set out the treaty position and reliefs that apply to you, with the numbers behind each option.

  3. File

    We prepare and submit to the IRS and HMRC, keeping the two sets of filings consistent with each other.

  4. Keep current

    Two tax calendars means deadlines all year. We track them and tell you before they arrive.

Questions we are asked most

The ones that come up in almost every first conversation with this group.

If you are a US citizen or green card holder, yes. The US taxes on citizenship rather than residence, so a return is generally due wherever you live, and the filing obligation exists even in years when no US tax ends up payable.

It should not be. The Foreign Earned Income Exclusion, foreign tax credits and the US-UK treaty exist to prevent it. Which of those gives the better outcome depends on your income mix, so the answer is worked out per client rather than applied by default.

It is a report of foreign bank and financial accounts, due when the combined balance of your non-US accounts tops $10,000 at any point in the year. It is a disclosure, not a tax, but the penalties for missing it are severe, and the threshold counts the total across all accounts rather than any single one.

Usually recoverable. The IRS Streamlined Filing Compliance Procedures exist for people whose failure to file was not wilful, and typically require three years of returns and six of FBARs. Coming forward voluntarily puts you in a considerably better position than being contacted first.

Pensions usually do, and the treaty often protects the growth from current US tax. ISAs are the more awkward case: the UK treats them as tax free, the US generally does not, and some holdings inside them can trigger additional reporting. Both go on the US return every year.
