Leaving United Kingdom: What to Know
Tax Departure Rules for United Kingdom
The UK does not impose a formal departure tax, but you must pass the Statutory Residence Test (SRT) to become a non-resident. Failing to meet the SRT criteria means HMRC may still consider you UK tax resident, even if you live abroad. You typically need to spend fewer than 16 days in the UK if you were resident for all of the previous 3 years, or fewer than 46 days if you have no significant ties.
Capital gains considerations: UK capital gains tax can still apply to UK property disposals even as a non-resident. The NRCGT rules require non-residents to file a return within 60 days of selling UK property.
Practical steps when leaving: Notify HMRC using form P85, close or restructure UK property lettings, and ensure your PAYE tax code is updated. Split-year treatment may apply in the year you leave.
Living and Working in Singapore
Singapore Tax System
Singapore's progressive tax rates top out at 24%, but foreign-sourced income is fully exempt from tax. There is no capital gains tax and no inheritance tax, making it extremely attractive for wealth accumulation.
Lifestyle in Singapore
Singapore is a global financial hub with exceptional safety, world-class healthcare, and seamless connectivity to all of Asia. English is an official language, making business and daily life straightforward for Anglophone expats.
Getting started: The Employment Pass (EP) or ONE Pass is required — Singapore does not have a digital nomad visa. EP requires a job offer from a Singapore employer with a minimum salary of S$5,000/month. ONE Pass requires S$30,000/month salary.
