UK Income Tax Calculator 2024/25
Our UK income tax calculator shows your full tax liability for the 2024/25 tax year, broken down by tax band. The UK uses a progressive tax system: the first £12,570 is tax-free (personal allowance), earnings from £12,571 to £50,270 are taxed at 20%, earnings from £50,271 to £125,140 are taxed at 40%, and earnings above £125,140 are taxed at 45%. The personal allowance is gradually withdrawn for incomes over £100,000, creating an effective 60% marginal rate between £100,000 and £125,140. Our calculator shows your effective tax rate alongside your marginal rate.
