๐ท๐บ Taxes in the UK for Expats (2026): Income Tax, Residency & Self Assessment
The UK tax system is well organised but has its own rhythm โ a tax year that starts in April, tax usually collected automatically through your salary, and a residence test that decides what you’re taxed on. This guide explains the essentials for expats in 2026: residency, Income Tax bands, National Insurance and when you must file. Tax is personal and rules evolve, so confirm details on GOV.UK or with an accountant before acting.

Are You a UK Tax Resident?
UK residency is decided by the Statutory Residence Test (SRT), based on days spent in the UK and your ties (work, home, family). Residents are generally taxed on worldwide income; non-residents only on UK income. The old “non-dom” remittance basis has been replaced by a new residence-based regime, which gives eligible new arrivals a period of relief on foreign income โ check whether you qualify.

The UK Tax Year and How Tax Is Collected
The UK tax year runs 6 April to 5 April. Most employees pay tax automatically through PAYE (deducted from your salary), so many people never file a return. The self-employed, landlords, higher earners and those with foreign income usually file a Self Assessment return instead.
Income Tax Bands and the Personal Allowance
For 2026, the standard personal allowance is ยฃ12,570 (tax-free). Above that, England, Wales and Northern Ireland use: 20% basic rate up to ยฃ50,270, 40% higher rate to ยฃ125,140, and 45% additional rate above. The personal allowance tapers away once income exceeds ยฃ100,000. Scotland sets its own bands and rates, which differ.
National Insurance
On top of Income Tax, employees and the self-employed pay National Insurance (NI) contributions, which fund the state pension and benefits. You’ll need a National Insurance number to work and be taxed correctly โ apply for one soon after arriving.
Taxes for the Self-Employed
If you’re self-employed you register with HMRC, file a Self Assessment return each year, and pay Income Tax and NI on your profits. Keep records of income and allowable expenses, watch the January filing/payment deadline, and note the ongoing move to digital record-keeping (Making Tax Digital).
Council Tax and Other Costs
Council tax is a separate local charge on your home (covered in our cost-of-living guide), not part of Income Tax. Depending on your circumstances you may also encounter capital gains tax, dividend tax and, on assets, inheritance tax โ areas where advice pays off.
Avoiding Double Taxation
The UK has double-taxation treaties with many countries, so foreign income or pensions aren’t taxed twice. How each type of income is treated depends on the treaty and your residence status, so cross-border advice is valuable if you have income or assets abroad.
