Understand HMRC’s estimate of your tax

Use this service to see HMRC’s latest calculation of your tax explained step by step. We compare it with this calculator’s own calculation from the same figures, and list income HMRC’s estimate does not include yet.

You give us permission to read the calculation from your HMRC records.

It takes around 5 minutes.
