Our approach
Residence decided on the rules, not the calendar.
Where you are tax resident — and under which country's rules — drives almost everything else in a cross-border return. US residence can turn on the substantial-presence test or a closer-connection claim; UK residence turns on the Statutory Residence Test; and when both countries claim you, the treaty tie-breaker decides, but only if the position is actually claimed.
We work the residence question through each country's test and, where needed, the treaty tie-breaker, and document the result so the same answer holds for pensions, gains and double-tax relief rather than being re-argued on every form.
- US substantial-presence and closer-connection position worked through explicitly
- UK Statutory Residence Test applied, with split-year treatment considered
- Treaty tie-breaker claimed and documented when both countries claim you

Fixed fees — no surprises
Treaty planning: £400–£800 + VAT depending on scope (single-article position vs comprehensive review). Form 8833 preparation is included.
