How UK Income Tax is Calculated
Income Tax is charged on earned income from employment, pensions, self-employment, and rental properties. The UK uses a progressive marginal tax band structure, meaning tax is only applied to income exceeding specific thresholds.

- Apply Personal Allowance Your first £12,570 of taxable income is taxed at 0%. If your total earnings exceed £100,000, the personal allowance reduces by £1 for every £2 earned above £100k until fully tapered at £125,140.
- Calculate Progressive Tax Bands Taxable income above your personal allowance is taxed at 20% (Basic Rate), 40% (Higher Rate), and 45% (Additional Rate).
