Please include a link to the relevant GOV.UK or HMRC source when reporting a rate discrepancy so we can verify and update promptly.

What we can help with

Rate or threshold corrections — if a published HMRC rate has changed and is not yet reflected on this site.

Factual errors — if methodology, description text or worked examples contain errors.

We cannot provide personalised tax advice or carry out Self Assessment calculations on your behalf.
