Understanding Bonus Taxation

Receiving a bonus is a great reward for hard work, but it can be confusing when the amount that lands in your bank account is less than you expected. This is because your bonus is treated as income and is subject to the same deductions as your regular salary: Income Tax, National Insurance, and, if applicable, Student Loan repayments.

The key thing to understand is that your bonus is taxed at your marginal tax rate. This is the rate of tax you pay on the last portion of your income. Your annual salary will have already used up your tax-free Personal Allowance and lower tax bands, meaning your entire bonus is typically taxed at your highest rate (e.g., 40% or 45%). You can see how this works with our Take-Home Pay Calculator.

Why your bonus feels heavily taxed

If you are a higher-rate taxpayer earning £60,000, your marginal rate is 40%. Any bonus you receive will have tax deducted at 40%, plus National Insurance and student loan repayments. Your tax-free allowance is used by your regular salary, so the entire bonus gets hit with your highest rate of tax, which is why the deductions seem so large.

How Deductions Are Applied

Your bonus is added to your regular pay for the period, and deductions are calculated on the total amount. This
