Income Tax Calculator
Work out how much income tax you pay on your salary, including the personal allowance taper above £100,000.
Your result
Updates as you type. Based on 2025/26 UK figures where relevant.
How this is worked out
Your personal allowance (£12,570, reduced by £1 for every £2 earned over £100,000) is tax-free. The rest of your income is taxed in bands: 20% basic rate, 40% higher rate and 45% additional rate. Scotland uses six bands from 19% to 48%.
Tips
- Check your tax code on every payslip. 1257L is the standard code for 2025/26; anything else deserves a quick look in your HMRC app.
- Pension contributions and salary sacrifice reduce your taxable pay, which matters most if you're near a band threshold.
- If your income is between £100,000 and £125,140, you lose personal allowance and face an effective 60% marginal rate. Pension contributions can bring it back.
