The marginal tax rate is the percentage of tax taken from your next pound of income.

Knowing your marginal tax rate is important if you want to know how much extra tax you need to pay if you earn more.

It’s all based on your tax bracket:

• 0% if you earn under £12,570
• 20% if you earn between £12,571 and £50,270
• 40% if you earn between £50,271 and £150,000
• 45% on any earnings beyond this
