Appeal against a tax decision

You have 30 calendar days to appeal. This begins from the date of the original notice or review conclusion letter.

You may be able to appeal late by giving reasons. The judge will decide if your appeal can go ahead.

This service is not currently available in Welsh, please continue or alternatively apply in Welsh (Cymraeg) using the paper form.

What you will need

  • a scan or photo of the original notice or review conclusion letter
  • reasons for your appeal so the judge can hear things from your side

You'll also need to complete an authorisation form (PDF, 47KB) (opens in new window) if you want someone to represent you and they are not a practising solicitor or barrister.
