About the UK Bonus Tax Calculator
Use this UK bonus tax calculator to estimate how much Income Tax and National Insurance you may pay on a bonus for the 2026/27 tax year.
Enter your annual salary and bonus amount to see the tax deducted from your bonus, your net bonus after PAYE, and your total take-home pay including salary and bonus.
Bonuses are taxed as employment income. If your bonus pushes your total earnings into a higher tax band, or above £100,000 where the Personal Allowance tapers, you may keep less of your bonus than expected.
This calculator is designed for UK employees paid through PAYE in England, Wales and Northern Ireland who want a quick estimate before or after receiving a bonus.
