Robert Gaines-Cooper v HMRC [2011] UKSC 47 pre-dates the modern Statutory Residence Test, but it remains one of the best-known warnings in UK residence planning: day counting alone does not tell the whole story.
The issue
Mr Gaines-Cooper had moved to the Seychelles and considered that he had become non-UK resident. HMRC disagreed. The Supreme Court ultimately held that he had not made a sufficient break from the UK and remained UK resident.
Public summaries of the case emphasise that the courts looked beyond physical absence. Family connections, the pattern of life and the quality of the continuing UK connection mattered.
Why it still matters after the SRT
The Statutory Residence Test made UK residence more mechanical, but it did not remove the need to track ties and factual context. The sufficient ties test still depends on family, accommodation, work, 90-day history and country ties, alongside the day count.
- Day counts answer “how much time?”
- Ties answer “what kind of connection?”
- Evidence answers “can you prove it?”
Where Atrium fits
Atrium’s value is not merely counting days. It keeps the day count connected to the surrounding facts: family profiles, journeys, supporting evidence and adviser-ready exports. That is the record a residence review actually needs.
