Calculating your Income Tax

What is a tax rate band?

A tax rate band is the amount of income which will be taxed at a particular percentage (tax rate). The current tax rates are 20% and 40%. A portion of your income will be taxed at 20% and the remainder will be taxed at 40%.

How rate bands work

If you are an employee, then your tax rate band will be shown on your Tax Credit Certificate. Your employer will use this to calculate the amount of tax to deduct from your weekly or monthly pay.

Under the Pay As You Earn (PAYE) system, tax rate bands are spread evenly throughout the year. If you are working for the full year, depending on how often you get paid your tax rate bands will be divided as follows:

  • 52 equal weekly amounts
  • 12 equal monthly amounts.

If you have a second or multiple jobs, you can divide your rate band between them.

Unused rate bands

You cannot get a refund of any unused tax rate bands and you cannot carry them over into another tax year.
