CASE STUDY
A decade in Geneva, a return to the UK
Situation
A British national with a long career across multiple countries with leading oil majors had been ordinarily resident in Geneva for ten years, filing Swiss tax returns annually while maintaining his family home in the United Kingdom. His income position was not straightforward: a UK occupational pension from his oil major employment already in payment, share options originally granted in the United States and vested during his Swiss residence, and Swiss property owned personally. His family remained in the UK throughout his Geneva years, which created an ongoing question around centre of vital interests under the UK-Switzerland Double Taxation Agreement — a question that required careful management each year to ensure his Swiss residency was correctly established and his UK non-resident status maintained.
On transitioning toward dual residence, he sold his Swiss property — crystallising a taxable gain — and purchased a replacement property in Switzerland, with the gain carried forward under Swiss immovable property tax rules. He now files tax returns in both Switzerland and the United Kingdom annually, with pension draws from his UK occupational scheme in payment and subject to DTA treatment in both jurisdictions.
Approach
Dryden ICS has managed his Swiss tax position throughout, and coordinates the interaction with his UK tax affairs across both jurisdictions. The annual Swiss filing reflects the full complexity of his position — pension income, the carried-forward property gain, and the ongoing centre of vital interests analysis under the DTA. The share options, granted in the United States and vested during his Swiss residence, introduced an additional layer of complexity that was navigated without triggering any HMRC enquiry.
The DTA work centres primarily on his UK occupational pension — ensuring that draws are correctly treated to avoid double taxation, with the interaction between Swiss cantonal tax and UK income tax managed in a way that reflects his dual residence position accurately. The centre of vital interests question, given his family’s continued presence in the UK, is addressed each year through the tax return process. The Geneva authorities have not formally challenged his Swiss residency, and his UK status has been formalised with HMRC.
Our partners hold the STEP qualification, which is directly relevant to the estate planning and cross-border structuring dimension of a case of this complexity — particularly given the ongoing property interests in both jurisdictions.
Outcome
After more than a decade of Swiss residence and a transition to dual residence across two jurisdictions, his tax position is correctly established, annually maintained, and optimised within the framework of the UK-Switzerland DTA. Double taxation on his pension draws has been avoided. The carried-forward Swiss property gain is correctly documented and reflected in each annual filing. The engagement is ongoing.
