Tax rate on your bonus
As a basic rate taxpayer, your bonus is taxed at 20% income tax plus 8% NI — so you keep around 72p in every £1 of bonus.
How much of a £5,000 bonus do you keep on £30,000?
On a £30,000 salary, a £5,000 bonus leaves you with £3,600 after Income Tax and National Insurance. Tax deducted from the bonus is £1,400, giving an effective bonus tax rate of 28.0%.
Your combined gross (salary + bonus) is £35,000, which produces a total take-home of £28,720 per year. Without the bonus, £30,000 alone gives £25,120 take-home — so the bonus adds £3,600 to your annual net pay.
Note: UK bonuses are taxed as regular income — there is no separate bonus tax rate. Your bonus is added to your salary and the combined amount is taxed at your marginal rate (28% income tax + NI for your salary level). Higher rate taxpayers (earning above £50,270) pay 40% income tax on their bonus, while basic rate taxpayers pay 20%. To reduce tax on a bonus, consider salary sacrifice into a pension.

Do bonuses get taxed more than salary?
Bonuses are taxed exactly the same way as salary — added to your gross income and taxed at your marginal rate. There is no special bonus tax rate in the UK. However, a large bonus can push you into a higher tax band, increasing the marginal rate on the bonus portion.
Can I reduce tax on my bonus?
Yes — you can ask your employer to pay your bonus into your pension (salary sacrifice), which reduces your taxable income. This is especially valuable if your bonus would push you into the 40% higher rate band. Alternatively, you can use charitable donations (Gift Aid) to offset some of the tax.
