Do I Pay Tax on a Bonus in the UK?
Updated July 2026 · 4 min read · Free calculator inside
Yes — in the UK, a bonus is not taxed differently from your normal salary. HMRC treats it as extra earnings in the pay period you receive it, so it is taxed through PAYE at your normal Income Tax and National Insurance rates. The confusion usually comes from the size of the deduction, which can look higher than expected.

A £5,000 bonus paid on top of your normal monthly salary can push that single month's pay into a higher tax band, so PAYE deducts more that month than your usual payslip. Over the full tax year this evens out — you are not charged a special "bonus tax rate", it is just your normal marginal rate applied to a bigger paycheque that month.
Worked example: a £5,000 bonus
If you are a basic-rate taxpayer receiving a £5,000 bonus, it is taxed at 20% Income Tax and 8% National Insurance (assuming you are within the main NI band) — about £1,400 in deductions, leaving roughly £3,600. If the bonus pushes part of your income above £50,270, that portion is taxed at 40% instead, so a large bonus can be taxed at more than one rate across its own value.
What else can reduce the tax on a bonus
- Paying some or all of the bonus into your pension via salary sacrifice avoids Income Tax and NI on that portion entirely.
- If the bonus tips you over £100,000, you start losing your personal allowance, creating an effective rate near 60% on that slice — pension contributions are the main way to avoid this.
- A bonus does not get a separate "bonus tax code" — any PAYE overpayment from a one-off large month is usually refunded automatically later in the tax year.
Frequently Asked Questions
Is a bonus taxed at a higher rate than salary?
No special bonus rate exists — it uses your normal Income Tax and NI bands. It can look like a higher rate because the bonus temporarily raises that month's income into a higher band, but this balances out across the tax year.
Can I avoid tax on a bonus?
Not entirely, but sacrificing some or all of it into a pension avoids Income Tax and NI on that portion, since pension contributions come out before tax.
Does a bonus count towards my student loan repayment?
Yes. A bonus is added to your income for that pay period, so if it pushes you above your student loan threshold, you repay 9% (or 6% for postgraduate loans) on the amount above it.
