First-tier Tribunal Tax Appeal Forms UK Guide

Overview

The First-tier Tribunal (Tax Chamber) is part of the UK's tribunal system and sits independently of HMRC. Its role is to look at HMRC decisions that the taxpayer believes are wrong and to apply the relevant tax law to the facts of the case.

It does not set tax policy, and it is not a forum for complaining about how an HMRC officer behaved or how long they took to respond. Those complaints go through HMRC's internal process and, if unresolved, to the Adjudicator or Parliamentary Ombudsman.

The tribunal can confirm an HMRC decision, cancel it, or substitute its own decision where the law allows. Cases are categorised as Default Paper, Basic, Standard or Complex, and the category affects how the case is managed, whether there is a hearing, and whether costs can be awarded.

Most taxpayers will need to have exhausted HMRC's internal review process, or have declined a review, before the tribunal will accept the appeal.

Key steps

1. Check you have an appealable decision. HMRC must have issued a written decision that carries a right of appeal. Common examples include tax assessments, closure notices, penalty notices, and certain VAT decisions. The letter you received should tell you whether an appeal right exists and the time limit, which is usually 30 days from the date of the decision.
2. Consider an HMRC internal review first. For most direct tax decisions, you can ask HMRC to review the matter internally before going to tribunal. This is free, often faster, and sometimes resolves the issue without a hearing. You can still appeal to the tribunal afterwards if you remain unhappy with the review outcome, though fresh time limits apply.
3. Complete the correct notice of appeal form. The tribunal uses a Notice of Appeal form which you submit to HM Courts & Tribunals Service. You will need to set out the decision you are challenging, the grounds of appeal, and attach a copy of the HMRC decision letter. Late appeals require a reason for the delay and permission to proceed.
4. Prepare your case and evidence. Gather the correspondence, calculations, contracts, invoices, or records that support your position. For Standard and Complex cases, the tribunal will issue directions setting deadlines for exchanging documents and witness statements. Keep everything organised by date and clearly labelled so it can be referred to at the hearing.
5. Attend the hearing or paper determination. Basic and Standard cases normally involve an oral hearing where you or your representative presents the argument and HMRC responds. Default Paper cases are decided on the documents alone. The tribunal will issue a written decision, usually within a few weeks, which is binding unless successfully appealed to the Upper Tribunal on a point of law.
