Questions & Answers
It is a curated library of US and UK tax guidance for people and businesses living across both systems. Each topic links to a dedicated resource, calculator or service page covering cross-border planning, IRS amnesty programmes, FBAR reporting, expat back taxes and private wealth so you can find the answer you need quickly.
Yes. The United States taxes citizens and Green Card holders on worldwide income regardless of residence, so an annual federal return is required even when you already pay UK tax. Foreign tax credits and the Foreign Earned Income Exclusion usually reduce or remove any US bill, but the filing obligation itself remains.
Most non-wilful expats use the IRS Streamlined Foreign Offshore Procedures, which require filing the past three years of returns and six years of FBARs plus a certification of non-wilful conduct. When accepted, the programme waives failure-to-file and FBAR penalties. Our Streamlined filing team manages the full submission for you.
You must file FinCEN Form 114 (the FBAR) if the aggregate value of your non-US financial accounts exceeds 10,000 US dollars at any point in the calendar year. It is filed electronically and separately from your tax return. Missing it can trigger significant penalties, so use our FBAR calculator to gauge your exposure.
US federal returns are generally due 15 April, with an automatic extension to 15 June for taxpayers living abroad and a further extension available to 15 October. UK Self Assessment is due by 31 October for paper returns and 31 January for online filing. We track both calendars so nothing is missed.
Yes. We are a dedicated US-UK cross-border firm, so a single team prepares your IRS and HMRC filings in a coordinated way. That means treaty positions, foreign tax credits and timing are handled consistently across both returns, reducing double taxation and the risk of conflicting advice from separate advisers.
