Appealing an HMRC decision in 2026? Here’s how internal reviews and tax tribunal appeals differ in the UK.
If you disagree with an appealable HMRC assessment, penalty or other decision, you may have options for challenging it rather than simply accepting the outcome. An HMRC internal review generally involves another HMRC officer reconsidering the decision, while eligible disputes may ultimately be taken to the independent First-tier Tribunal.
This video explains who these routes may apply to, how an internal review differs from tribunal proceedings, and the practical factors to consider before choosing your next step.
Deadlines can be important in HMRC disputes, and the correct procedure depends on the type of tax and decision involved. Missing an appeal deadline, submitting weak grounds or following the wrong route can make resolving the dispute more difficult.
