Relocation & Expat Advisory
Tax planning for your move, to or from the UK
End-to-end tax support for people and families relocating to or from the UK, covering residency, timing, and overseas obligations.
The Short Answer
Leaving the UK does not automatically end your UK tax obligations, and getting the timing and paperwork right can be the difference between a clean break with a refund and an unexpected bill years later. Your position turns on whether you become non-resident under the Statutory Residence Test, whether you qualify for split-year treatment, and what UK-source income or gains you leave behind.
Moving to the UK usually makes you UK tax resident, which can bring your worldwide income and gains within the UK tax net. But new arrivers often pay tax only from their date of arrival, and many qualify for a four-year exemption on foreign income and gains. The detail decides how much you pay.
Horizon UK Tax Solutions specialises in cross-border departures and arrivals on a fixed-fee basis, so you know the cost of getting it right before any work begins.
