US TAX SERVICES

US citizens and Green Card holders must file a US federal return on worldwide income regardless of where they live. If your gross income exceeds the standard filing threshold you must file Form 1040 annually, even while UK-resident. UK tax paid can often be credited, but the US filing obligation itself does not simply disappear.

FBAR (FinCEN Form 114) reports foreign financial accounts to the US Treasury when their combined value exceeds 10,000 dollars at any point in the year. It is filed separately from your tax return, electronically through FinCEN, with an automatic extension to 15 October. UK bank, savings and investment accounts all count toward the threshold.

Generally no. The US-UK tax treaty and foreign tax credit rules are designed to prevent double taxation. UK tax paid can usually be claimed as a US foreign tax credit on Form 1116, and the Foreign Earned Income Exclusion may exempt some earned income. Careful planning ensures the same income is not effectively taxed twice.

FATCA requires US persons to report specified foreign financial assets on Form 8938 once they exceed set thresholds, which are higher for those living abroad. It also requires UK banks to report US account holders to the IRS. FATCA reporting is in addition to, not a replacement for, your separate FBAR obligation.

The US tax year follows the calendar year, ending 31 December, with returns generally due 15 April and an automatic extension to 15 June for those living abroad. The UK tax year runs 6 April to 5 April, with online Self Assessment returns due by 31 January. These mismatched years require careful coordination.

Yes. As specialist US and UK cross-border accountants we prepare IRS federal and state returns alongside HMRC Self Assessment, coordinating foreign tax credits, treaty positions and reporting so both sides align. Handling both jurisdictions together avoids conflicting positions, prevents double taxation and keeps you compliant with the IRS and HMRC simultaneously.
