 What Is a Bonus and How Is It Paid?

A bonus is extra money your boss gives you besides your regular paycheck. Companies might give these for doing a great job reaching goals, or as a yearly “thanks.”

Bonuses can be given in several ways:

• A single cash payout
• Rewards tied to how well you perform
• End-of-year or holiday bonuses

No matter why you get one, it counts as income so you’ll have to pay tax on it. Before you decide how to use it, remember you won’t keep the full amount.

Why Bonuses Are Taxed Differently

Here’s where it gets a bit confusing. Bonuses don’t get taxed using a different rate. They get taxed the same way as your regular paycheck. However, because they get added to your normal income, it might seem like they are taxed at a higher rate.

This can be tricky because the amount you take home might end up being less than you thought. Your tax bracket and the PAYE system decide how much of your bonus you keep.

PAYE: The System Behind the Scenes

PAYE, which means Pay As You Earn, is the UK system where employers take off Income Tax and National Insurance from your pay before giving it to you.

When you get a bonus, the money doesn’t just come straight to you. PAYE works out how much tax is owed based on what you earned during that pay period. If you earn more in that period, the system assumes you’ll keep earning at that level for the rest of the year.

Think of PAYE like predicting the weather: it guesses how much sunshine (money) you might see throughout the year and adjusts the umbrella (tax) to match—even if it ends up raining (a one-off bonus).

How Much will I Pay Tax on Bonus?

This is the question: How much will I pay tax on bonus?

Let’s keep it simple:

If you earn:

• Up to £12,570 – You don’t pay Income Tax (Personal Allowance)
  
• £12,571 – £50,270 – You pay 20% (Basic Rate)
  
• £50,271 – £125,140 – You pay 40% (Higher Rate)
  
• Above £125,140 – You pay 45% (Additional Rate)
  

So, your bonus gets stacked on top of your income and taxed accordingly. If your bonus pushes you into a new bracket—even temporarily—you may pay a higher rate on that part only.

Understanding Your Tax Code

Your tax code helps employers know how much tax-free income you’re entitled to. The most common one is 1257L, meaning you can earn £12,570 before paying tax.

A wrong tax code can lead to too much or too little tax taken from your bonus. Always check your payslip or contact HMRC if something seems off.

Example: Bonus Tax Calculation in Action

Let’s say:

• Your annual salary is £40,000
  
• You receive a £5,000 bonus
  

Your total income becomes £45,000. Here’s how tax might look:

• The first £12,570 – Tax-free
  
• The next £37,430 – Taxed at 20%
  
• Your bonus falls within the 20% band, so it will also be taxed at 20% Income Tax + National Insurance (around 12%)
  

But if you earned £49,000 and got a £5,000 bonus, the top £4,000 would fall into the 40% tax band, meaning that part of the bonus is taxed higher rate.

National Insurance and Bonuses

Bonuses aren’t just taxed through Income Tax—National Insurance Contributions (NICs) also apply.

For employees:

• You pay 12% on earnings between £12,570 and £50,270
  
• You pay 2% on anything above
  

So yes, your bonus will trigger National Insurance too.

How Employers Calculate Bonus Tax

Employers often include the bonus in your monthly wages and process it through the PAYE system. This might result in you being taxed more for the moment if your monthly earnings make it seem like your yearly income is higher than it is.

The system calculates your income for the year based on that particular month. You might pay extra at first, but things should balance out over time.

Impact of Large Bonuses on Tax Brackets

A large bonus can bump you into a higher tax band, but only for the part that crosses the threshold. You won’t lose your entire bonus to tax, just a higher percentage on the extra bit.

Example: If you earn £48,000 and get a £7,000 bonus:

• £2,270 of that bonus will be taxed at 40%
  
• The rest still gets 20%
  

So don’t worry—you’re not losing half your bonus.

Is My Bonus Pushing Me into a Higher Tax Rate?

It might seem that way, but keep in mind that the part that moves into a higher tax bracket gets taxed at the higher rate. The rest stays taxed at its usual rate.

A lot of people think getting a bonus could mean less take-home pay than if they hadn’t gotten one, but that’s not true. You’ll always end up with more money just not as much more as you’d hope.

Can I Reduce the Tax on My Bonus?

Short answer: yes, in some situations.

You might reduce tax by:

• Increasing pension contributions
  
• Choosing salary sacrifice schemes
  
• Timing bonuses in a lower-income year
  

It’s all about planning and using smart financial tools.

Pensions and Salary Sacrifice Options

You can ask your employer to pay your bonus directly into your pension. This avoids Income Tax and National Insurance on that amount. It’s called salary sacrifice.

This option helps grow your retirement pot while saving tax. However, check if your employer allows it.

Other Deductions on Bonuses

Beyond tax and NICs, bonuses might face:

• Student Loan repayments
  
• Workplace pension auto-enrolment
  
• Court orders or child maintenance (if applicable)
  

All these affect what finally hits your account.

What Happens at the End of the Tax Year?

If too much tax was taken due to a miscalculated bonus, HMRC may issue a refund after April 5th (the end of the tax year). This usually comes through your next payslip or a P800 tax calculation.

Always check your P60 or P45 and compare it with your expected earnings.
