Estimate your Income Tax for a previous tax year

Use this service to estimate how much Income Tax you should have paid for a previous tax year.

There are different ways to:

• see how much Income Tax you paid last tax year (6 April 2022 to 5 April 2023)
• check your Income Tax payments for the current tax year (6 April 2023 to 5 April 2024)

If you’re self-employed, use the HMRC self-employed ready reckoner to budget for your tax bill.

You may be able to claim a refund if you’ve paid too much.

Before you start

You need to be:

• born after 5 April 1938
• a basic or higher rate taxpayer earning under £100,000
• getting the Personal Allowance

You need details of:

• your earnings, before and after tax - get this from your P60
• any savings - get this from your bank statements or annual statement from your bank or building society
• any Gift Aid donations you’ve made to charity

Who cannot get an estimate online

You cannot get an estimate online if you:

• get taxable state benefits
• are entitled to claim Married Couple’s Allowance
• were born on or before 5 April 1938 and get the higher allowances
• have other taxable income, for example from dividends and trusts
• are a higher rate taxpayer and want to estimate your Gift Aid tax relief

You can check you’ve paid the right tax by contacting HMRC or by getting help from an accountant.
