What expats should know about United Kingdom

The UK tax year runs from April 6 to April 5. Self-assessment is required for self-employed individuals and those with income above £150,000. National Insurance contributions fund the state pension and NHS access. The UK has a statutory residence test that determines your tax residency status based on days spent in the country.

Healthcare, visa requirements, and banking setup are closely tied to your tax and employment status. Many expats find that the bureaucratic aspects of relocation take longer than expected — starting the process early gives you more options.

For a comprehensive overview of your personal financial situation in United Kingdom, the best approach is to combine multiple analyses: tax comparison, cost of living, salary benchmark, and visa options.

Key considerations before moving to United Kingdom

Tax residency: Most countries consider you a tax resident after 183 days. Check United Kingdom's specific rules and any transitional provisions.

Double taxation: Verify if your origin country has a double taxation agreement with United Kingdom. This prevents being taxed twice on the same income.

Healthcare: Public vs private healthcare access depends on your visa and employment status. Budget for private insurance during the transition period.

Banking: Open a local bank account before or shortly after arrival. Many services require a local IBAN. Multi-currency accounts can help during the transition.

Cost timing: The first year typically costs 20-30% more than subsequent years due to deposits, setup fees, and learning where to find value.
