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
- check your Income Tax payments for the current tax year
If you are 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 have paid too much.
