UK Tax System Basics

The UK has a progressive income tax system with different tax bands. The tax year runs from April 6th to April 5th the following year.

Key Elements of UK Taxation

  • Personal Allowance: Everyone has a tax-free allowance (currently £12,570).
  • National Insurance: A separate contribution that funds state benefits.
  • PAYE System: Most employees have tax deducted automatically through the Pay As You Earn system.

Understanding your tax code is important in the UK as it determines how much tax-free income you're entitled to. Self-employed individuals need to complete a Self Assessment tax return annually.
