If you disagree with a decision HMRC have made about your taxes – such as issuing a penalty – you usually have a legal right to ask a different person to review that decision. If you are unhappy with the outcome of that review, you can appeal to a Tribunal to ask a judge to consider your case.

If you cannot agree your position with HM Revenue & Customs (HMRC) regarding an appealable decision, you can ask an independent Tribunal to make a decision.
