How Much Tax Will I Pay on Bonus in the UK?

Do You Pay 40% Tax on Bonuses?

One of the most common complaints among UK employees is: “Do you pay 40% tax on bonuses?” The reality is that many people do.

Because a bonus is a “top-up” to your existing salary, it is frequently taxed at your highest applicable rate. Even if you are a basic-rate taxpayer normally, a large bonus can temporarily (or permanently for that tax year) push you into the 40% bracket.

Furthermore, Income Tax isn’t the only deduction. You must also account for National Insurance (NI). For the 2026 tax year, employees pay:

8% on earnings between the Primary Threshold (£1,048 per month) and the Upper Earnings Limit (£4,189 per month).
2% on anything above the Upper Earnings Limit.

If you are a higher-rate taxpayer, you pay 40% Income Tax plus 2% NI, meaning 42% of your bonus goes straight to HMRC. If you also have a Student Loan, you might see another 9% deducted, bringing your total effective “tax” rate on that bonus to a staggering 51%.

How Much Tax Comes Out if a Bonus?

To visualise this, let’s look at three common scenarios for a £5,000 bonus:

Scenario A: The Basic Rate Earner

Salary: £30,000
Income Tax (20%): £1,000
National Insurance (8%): £400
Take-Home Bonus: £3,600
Effective Loss: 28%

Scenario B: The Higher Rate Earner

Salary: £60,000
Income Tax (40%): £2,000
National Insurance (2%): £100
Take-Home Bonus: £2,900
Effective Loss: 42%

Scenario C: The Student Loan Payer (Plan 2)

Salary: £60,000
Income Tax & NI: £2,100
Student Loan (9%): £450
Take-Home Bonus: £2,450
Effective Loss: 51%

As you can see, the question of “how much tax comes out if a bonus” depends heavily on your existing financial profile. For many professionals, seeing more than half their hard-earned bonus vanish can be demoralising.

The Dangerous “60% Tax Trap”

While 40% and 45% are the official top rates of tax, there is a “hidden” tax rate in the UK that catches many high earners off guard. This is often referred to as the 60% tax trap.

How the Trap Works

The standard Personal Allowance is £12,570. This is the amount you can earn before paying any Income Tax. However, for every £2 you earn over £100,000, you lose £1 of your Personal Allowance.

If your regular salary is £95,000 and you receive a £10,000 bonus, your total income becomes £105,000. Not only do you pay 40% tax on that £10,000 bonus, but you also lose £2,500 of your tax-free Personal Allowance.

That “lost” allowance is now taxed at 40%, adding an extra £1,000 to your tax bill.

Tax on Bonus (£10k at 40%): £4,000
Extra tax due to lost allowance: £2,000
Total Tax: £6,000 (which is 60% of the £10,000 bonus)

This excludes National Insurance and Student Loans. When those are added, you could effectively be working for less than 30p on the pound for that bonus.

How to Avoid the 60% Tax Trap?

If you are approaching the £100,000 threshold, you are likely looking for ways to mitigate this heavy tax burden. The good news is that there are legitimate, HMRC-approved methods to stay efficient.

1. Pension Contributions (Bonus Sacrifice)

The most effective way to avoid the 60% tax trap is through “Bonus Sacrifice” or “Salary Sacrifice.” You can ask your employer to pay part or all of your bonus directly into your pension scheme.

Because pension contributions are made before tax, a £10,000 bonus going into a pension costs you nothing in tax or NI.

Furthermore, it keeps your “Adjusted Net Income” below the £100,000 mark, preserving your Personal Allowance and your eligibility for 30 hours of free childcare and Tax-Free Childcare.

2. Charitable Donations

Donating to charity via Gift Aid reduces your “Adjusted Net Income.” For high earners, this can pull you back under the £100,000 or £50,270 thresholds, reducing the overall tax on bonus impact while supporting a cause you care about.

3. Transferring Assets to a Spouse

If you are self-employed or a business director paying yourself a bonus/dividend, you may have the flexibility to distribute income to a spouse who is in a lower tax bracket. However, for PAYE employees, this is generally not an option.

Why Does My Bonus Look Smaller Than Expected? (The Underpayment Myth)

Sometimes, you might receive a bonus and notice that the tax deduction is even higher than your marginal rate. This usually happens for one of two reasons:

Month-One Tax Codes: If HMRC’s systems think your “one-off” bonus is actually your new monthly salary, they may project your annual income to be much higher than it actually is. This results in an emergency tax code or a “Month 1” basis, where your annual allowances aren’t spread out correctly.
National Insurance is Weekly/Monthly: Unlike Income Tax, which is cumulative over the year, NI is calculated based on the specific pay period. A large bonus in a single month can push you into the 2% NI bracket for that month, which actually saves you a bit of NI compared to if the money were spread over 12 months, but the Income Tax often compensates for this.

If you have overpaid tax due to a bonus, you can usually claim a refund at the end of the tax year or wait for HMRC to automatically adjust your tax code.

Impact on Benefits and Childcare

When calculating the tax on bonus, don’t just look at the payslip. Look at the wider impact on your household finances.

High Income Child Benefit Charge: If your bonus pushes your income over £60,000 (for the 2024/25 year), you will start losing your Child Benefit via a tax charge. At £80,000, the benefit is lost entirely.
Tax-Free Childcare: If one parent earns over £100,000 (even by £1 because of a bonus), the household loses eligibility for the Tax-Free Childcare scheme (worth up to £2,000 per child per year) and the 30 hours of free childcare for 3-4 year olds.

In these cases, a £5,000 bonus could actually result in a net loss for the family if it triggers the loss of these benefits. This makes “Bonus Sacrifice” into a pension even more critical.

Strategic Planning: Managing Your Bonus

As expert tax advisors, we always suggest looking at the “net-net” position. If you are expecting a bonus, follow these steps:

Check your total income for the year: Use your last payslip (P60 or March payslip) to estimate your year-end position.
Calculate the threshold impact: Will this bonus push you over £50,270, £100,000, or £125,140?
Negotiate timing: If your bonus is due in March but would push you into the 60% trap, you could ask your employer to pay it in April (the new tax year) if you expect your income to be lower then. (Note: Most large corporations have fixed payroll dates, but smaller firms may be flexible).
Use Pension Carry Forward: If you want to sacrifice your bonus into your pension but have already hit your £60,000 annual allowance, you may be able to use “carry forward” from the previous three tax years.

Comparing the UK to Other Regions

While the UK’s tax on bonus might seem high, it is structured differently than in the US or some EU countries. In the US, bonuses are often “withheld” at a flat 22% rate, leading to a surprise tax bill or refund later.

The UK’s PAYE system tries to be more accurate in real-time, which is why the deduction feels so heavy, it is often exactly what you owe.

FAQs: Tax on Bonus in the UK

1. Is a bonus taxed differently from a regular salary?

No. HMRC treats a bonus as “earnings.” It is added to your total income for the year and taxed at your marginal Income Tax rate. You also pay Class 1 National Insurance on it.

2. Can I get a tax-free bonus?

Generally, no. However, there are minor exceptions. For example, “Trivial Benefits” (under £50) are tax-free. Additionally, if you work for a company owned by an Employee Ownership Trust (EOT), you can receive a tax-free bonus of up to £3,600 per year.

3. How much tax will I pay on a £1,000 bonus?

If you are a basic-rate taxpayer, you will pay £200 in tax and £80 in NI (at 8%), leaving you with £720. If you are a higher-rate taxpayer, you will pay £400 in tax and £20 in NI (at 2%), leaving you with £580.

4. Does a bonus affect my Student Loan repayments?

Yes. Student loan repayments are calculated on your gross earnings above a certain threshold. A bonus will increase your gross earnings for that pay period, resulting in a higher student loan deduction.

5. Why was my bonus taxed at 50%?

This usually happens if you are an additional-rate taxpayer (45% tax + 2% NI) or if the bonus pushed you into the 60% tax trap (loss of Personal Allowance) and included other deductions like Student Loans.

6. Can I put my bonus into my pension?

Yes, this is called “Bonus Sacrifice.” It is one of the most tax-efficient ways to handle a bonus, as it avoids Income Tax and National Insurance entirely, provided you stay within your annual pension allowance.
