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 2016 to 5 April 2017)
- check your Income Tax payments for the current tax year (6 April 2017 to 5 April 2018)
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.
