Additional rate tax

  • 2 min read

The additional rate tax is the top rate of Income Tax in the UK. You pay this when you earn more than £150,000 per year. 

How does Income Tax work?

Income Tax is paid by everyone in the UK who earns more than £12,570 per year. The first £12,570 is Income Tax-free and known as the Personal Allowance. However, when you earn more than £100,000 per year, you gradually lose your eligibility for this allowance, £1 at a time. 

Take a look at the Income Tax rates for the 2022/23 tax year:

Income Tax rate
Up to £12,570 0% Personal allowance
£12,571 to £50,270 20% Basic rate
£50,271 to £150,000 40% Higher rate
Over £150,000 45% Additional rate

 

Additional tax rate in action

In the 2022/2023 tax year, the additional rate is 45% on earnings above £150,000. So if your annual income is £170,000, for example, you’re an additional rate taxpayer. This means that you pay 45% tax on your income above £150,000. 

In this case, that’s broken down like this:

  • 45% on £20,000
  • 40% on £99,730
  • 20% on 50,270

If you’re in Scotland, the additional rate tax is actually 46% on earnings above the same £150,000 limit.

When do I pay 60% tax?

When you earn more than £100,000, you start to lose your entitlement to the Personal Allowance. You lose it by £1 for every £2 that you earn over £100k. However, you’re not taxed at 45% until you earn over £150,000 which means that between £100,000 and £125,140, you’re taxed an extra 20% on the Personal Allowance that you’re losing. This can be confusing to get your head around, so take a look at our guide on the tax implications of earning over 100k – and how to get around it.
