What we prepare and file

Tax returns and compliance, US and UK, under one roof

Most of our clients come to us for the filings themselves. These are the returns and reports we prepare every year, each with a fixed fee quoted in writing before we start.

US tax returns (Form 1040) Federal and state returns for US citizens and green card holders living in the UK.

UK Self Assessment HMRC returns for the self-employed, landlords, high earners and people with US income.

US–UK cross-border returns Both countries prepared together so credits, treaty positions and dates line up.

Streamlined Foreign Offshore filings Three years of returns and six years of FBARs to catch up on missed US filings.

FBAR (FinCEN Form 114) Annual reporting of UK accounts, ISAs and pensions over $10,000 combined.

FATCA / Form 8938 Foreign financial asset reporting filed with your US return above the thresholds.

W-8BEN, W-8BEN-E and W-9 The right US withholding form, with treaty rates applied where they apply.

Late and catch-up US filings Delinquent FBARs and late returns where the Streamlined route does not apply.
