The short answer
Your tax calculation is HMRC's working out of your tax, from what you've sent. In EasyTaxer, it's under Tax, then Calculations. During the year, you can ask HMRC for an estimate. After the year ends, you check the calculation your final declaration is based on.
-
An estimate during the year
After you send a quarterly update, you can get an estimate of your tax bill. In EasyTaxer, select Run in-year calculation, which sends a calculation request to HMRC. HMRC includes other information it already holds, but the estimate is less accurate if you haven't told HMRC about all your income yet.
-
Reading a calculation
Each calculation is listed with its period, type, outcome and liability. Open one to see HMRC's details. A tax calculation shows your total income on which tax is due, your allowances and reliefs, the total you owe for the year, and how HMRC worked it out.
-
HMRC Assist
You can also ask HMRC Assist to check a calculation for common mistakes. HMRC Assist gives feedback and highlights errors for your tax return, using what you've submitted and the data HMRC holds. It's advice: you read HMRC's messages, and can tell HMRC you've read them.
-
At the year end
After the tax year ends, and once every quarterly update is complete, select Intent to Finalise. That runs the finalisation calculation, the basis for your final declaration. View it, and check it's correct, before you submit. For 2026 to 2027, that's after 5 April 2027.
