United Kingdom
Europe
The United Kingdom has a comprehensive tax system administered by HMRC. The tax year runs from April 6 to April 5. The UK taxes residents on worldwide income and non-residents on UK-sourced income. The system includes Income Tax, National Insurance contributions, Value Added Tax (VAT), Capital Gains Tax, Corporation Tax, and Inheritance Tax. Scotland has its own income tax rates and brackets separate from England, Wales, and Northern Ireland.
How Taxation Works in United Kingdom
Understand the basics of United Kingdom's tax system, who pays tax, and how rates apply to individuals and businesses.
Tax System
The UK uses a Pay As You Earn (PAYE) system for employment income, where employers deduct tax and NI contributions before paying wages. Self-employed individuals make payments on account twice a year. The Self Assessment system requires individuals to file annual tax returns and pay any additional tax owed.
Residents
UK tax residents are taxed on worldwide income. Non-residents are taxed only on UK-sourced income. Employers deduct PAYE from employee wages. Self-employed individuals pay Class 2 and Class 4 NI contributions.
Non-Residents
UK tax residents are taxed on worldwide income. Non-residents are taxed only on UK-sourced income. Residency is determined by the Statutory Residence Test (SRT), which considers days present, home availability, and work in the UK.
Individuals
The UK uses a three-band progressive income tax system: Basic rate 20%, Higher rate 40%, and Additional rate 45%. The personal allowance of £12,570 reduces taxable income. Scotland has separate rates and bands.
Businesses
Corporation tax is 25% for companies with profits over £250,000, 19% for small companies with profits up to £50,000, and marginal relief for companies between £50,000 and £250,000. VAT is 20% on most goods and services.
Tax Year
The UK tax year runs from April 6 to April 5. The 2024/25 tax year covers April 6, 2024 to April 5, 2025.
Personal Allowance
The amount of income you can earn each year before paying income tax. £12,570 for 2024/25, reduced by £1 for every £2 of income above £100,000.
Residency and Domicile
UK tax residents are taxed on worldwide income. Non-residents are taxed only on UK-sourced income. Domicile status affects how foreign income is taxed.
