A First-tier Tax Tribunal decision is the written ruling that closes out an appeal against HM Revenue and Customs, setting out the facts the judge found, the law applied, the outcome, and the reasoning behind it. The First-tier Tribunal (Tax Chamber) is the independent judicial body that hears these appeals, covering income tax, corporation tax, VAT, capital gains tax, inheritance tax, national insurance contributions, and customs and excise duties.1Courts and Tribunals Judiciary. First-Tier Tribunal Tax Chamber Once you have a decision in hand, it does three things: it tells you what you owe or are owed, it becomes a public document other taxpayers can read, and it starts the clock on your right to challenge it.
Where to Read Published Decisions
Decisions issued from May 2022 onward are published on the Find Case Law website, run by the National Archives. You can filter by the name of the person or company involved, the date, or the judge.2GOV.UK. Tax Tribunal Decisions Anything decided before May 2022 sits on a separate First-tier Tribunal decisions website, which holds records up to April 2024.3Courts and Tribunals Judiciary. Decisions of the First-Tier Tribunal Tax Chamber
The most reliable way to pull up a specific case is by neutral citation number or appellant name. Most decisions are public, but the tribunal can anonymise parties where sensitive financial information is involved, and some private hearings produce decisions that are not published at all. Subscription platforms such as Westlaw UK and LexisNexis carry tribunal decisions alongside commentary, which practitioners use to trace how a particular argument has fared across multiple hearings.
What a Decision Notice Contains
Decision notices follow a consistent shape. They open with the background facts and how the dispute got to the tribunal. They set out the statutory provisions and legal principles the judge considered, summarise each side’s arguments, and then explain, in the reasoning section, how the law was applied to the facts to reach the outcome. That reasoning, sometimes called the ratio decidendi, is the part that matters if you or someone else wants to rely on the case later.
Not every decision is issued with full reasoning. Under Rule 35 of the 2009 Procedure Rules, the tribunal can send out either a summary of findings and reasons or a full written statement. The distinction is easy to overlook and hard to recover from. You cannot apply for permission to appeal on the basis of a summary alone. If you only received the summary, you have 28 days from the date the decision was sent to request the full written reasons. Miss that window and the door to any appeal quietly closes.
How Much Weight These Decisions Carry
A First-tier Tribunal decision does not bind other First-tier judges. If one judge decides a particular transaction is not subject to VAT, another judge hearing a near-identical case the following month is free to reach the opposite conclusion. These decisions are persuasive only. A later judge may find the reasoning useful, but is not required to follow it.
Binding authority sits above the First-tier. The Upper Tribunal (Tax and Chancery Chamber) is a superior court of record, and its rulings on points of law bind all First-tier Tribunal judges.4Courts and Tribunals Judiciary. Guidance on the Publication of Decisions in the Upper Tribunal (Tax and Chancery Chamber) Above the Upper Tribunal sit the Court of Appeal and the Supreme Court. When you research First-tier decisions to gauge your own case, read them as indicators of how an argument has been received, not as guarantees of how yours will go.
Challenging a Decision You Disagree With
If you have lost and believe the decision was legally wrong, you can seek permission to appeal to the Upper Tribunal. The word doing the work there is “legally.” Under section 11 of the Tribunals, Courts and Enforcement Act 2007, appeals from the First-tier Tribunal to the Upper Tribunal lie on points of law only.5Legislation.gov.uk. Tribunals, Courts and Enforcement Act 2007, Section 11 Disagreeing with how the judge weighed the evidence or assessed a witness is not enough. You need to point to something like a misinterpretation of a statute, a failure to apply the correct legal test, or a finding of fact that no reasonable judge could have reached.
The deadline is 56 days from the date on the full written reasons.6GOV.UK. Appeal to the Tax Tribunal – The Tribunal’s Decision This is where the summary-versus-full-reasons point becomes practical. If you only ever received a summary decision, the 56 days do not start until the full reasons arrive, but you must have asked for those full reasons within 28 days of the original notice. Get that sequence wrong and there is no appeal to bring.
The application goes first to the First-tier Tribunal itself, where a judge decides whether the proposed grounds have a reasonable prospect of success. If permission is granted, the case moves to the Upper Tribunal. If permission is refused, you can apply directly to the Upper Tribunal within one month of the refusal notice.7Courts and Tribunals Judiciary.

When a Set-Aside Fits Better Than an Appeal
Not every problem with a decision is a legal one. Under Rule 38 of the 2009 Procedure Rules, the tribunal can set aside its own decision if a procedural failure undermined the fairness of the proceedings.8Legislation.gov.uk. The Tribunal Procedure (First-tier Tribunal) (Tax Chamber) Rules 2009 – Rule 38 Common examples include a document that never reached a party who should have received it, or a party being absent from a hearing they were entitled to attend.
A set-aside is not an appeal. No higher court reviews the reasoning. The original decision is wiped and the case is reheard by the First-tier Tribunal. If your complaint is that the process went wrong rather than that the law was misread, a set-aside application is usually the right route.
The Costs Exposure to Check Before You Do Anything
In most First-tier Tribunal cases each side pays its own costs regardless of who wins. The tribunal can only order one party to pay the other’s costs in limited circumstances: where a party or their representative has acted unreasonably in bringing or conducting the proceedings, where a wasted costs order is appropriate, or in Complex cases where the taxpayer has not opted out of cost liability within 28 days of the allocation notice.9Legislation.gov.uk. The Tribunal Procedure (First-tier Tribunal) (Tax Chamber) Rules 2009 – Rule 10
That Complex opt-out is easy to miss. If your case was allocated as Complex, you would have received a notice giving you 28 days to write to the tribunal asking that the case be excluded from potential cost liability. If nothing was done, a losing decision can come with an order to pay HMRC’s legal costs, which in a substantial tax dispute is not a small figure. Anyone weighing whether to accept a decision or pursue it further should check the allocation category first, because it changes the maths.
