Why does salary matter? Your bonus is taxed at your marginal rate — the rate on your next pound of income. If your salary is £35,000 (basic rate), the bonus is taxed at 28% (20% tax + 8% NI). If your salary is already £55,000 (higher rate), the bonus is taxed at 42% (40% tax + 2% NI).
Important: Your bonus isn't taxed at a special "bonus tax rate." PAYE may over-deduct in the month you receive it, but this corrects automatically in subsequent months. See our bonus tax calculator for exact figures.
How Your £50,000 Bonus Is Taxed
In the UK, bonuses are taxed as part of your regular income — there is no special "bonus tax" rate. Your £50,000 bonus is added to your salary for the pay period in which it is received, and income tax and National Insurance are deducted at your marginal rate. This can result in a higher deduction than expected if the bonus pushes you into a higher tax band for that month.
Why Bonus Tax Looks High
Many people are surprised by how much tax is deducted from their bonus. This happens because PAYE calculates tax as if you will receive the same total (salary + bonus) every month. If your annual salary plus bonus pushes you above the higher-rate threshold (£50,270), the portion above this level is taxed at 40%. Your employer may also deduct emergency-rate tax if the bonus is processed separately. If too much tax is taken, it is usually corrected automatically in subsequent pay periods within the same tax year.
Reducing Tax on Your Bonus
The most effective way to reduce tax on a bonus is to redirect some or all of it into your pension through salary sacrifice. This saves both income tax and National Insurance. On a £50,000 bonus, diverting it to your pension could save you £16,000-£21,000 in tax and NI depending on your marginal rate. You can also use Gift Aid donations, which provide relief at your marginal rate. See salary sacrifice calculator for pension tax savings.
