Tax Tribunal Appeal Solicitors

The First-tier Tax Tribunal is the independent court that hears appeals against HMRC decisions. It decides tax disputes on their legal merits — not on HMRC's view of the matter. A solicitor gives the taxpayer the best chance of success at the tribunal.

The First-tier Tribunal (Tax Chamber) hears appeals against HMRC assessments, penalties, and decisions on a wide range of taxes — income tax, corporation tax, VAT, capital gains tax, inheritance tax, and PAYE. The Upper Tribunal (Tax and Chancery Chamber) hears appeals from the First-tier Tribunal on points of law. A solicitor will manage the appeal from the notice of appeal through to the final hearing — preparing the grounds, managing the evidence, engaging expert witnesses, and presenting the taxpayer's case at the hearing. Tax tribunal appeals that are properly prepared and presented are significantly more likely to succeed than those pursued without legal representation.

Tax Tribunal Appeals — Process & Strategy

Tax tribunal appeals — how the process works and how a solicitor manages each stage to give the taxpayer the best chance of success.

A tax tribunal appeal is litigation — it has formal pleadings, exchange of evidence, witness statements, and a hearing before a judge. A solicitor will manage every stage of the process, ensuring the taxpayer's case is presented as compellingly as possible.

✓

Notifying the appeal — grounds and deadlines

An appeal to the First-tier Tax Tribunal must be notified using HMRC's prescribed form (T240 for direct taxes; VAT and duty appeals have separate forms) within 30 days of the HMRC review conclusion or HMRC's refusal to accept a review request. Late appeals require the tribunal's permission — which is not always granted. The grounds of appeal set out the legal and factual basis of the taxpayer's challenge — they must be sufficiently specific to identify the issues the tribunal will decide. A solicitor will draft grounds that are legally precise, factually complete, and strategically framed — giving the taxpayer the strongest possible start to the appeal.

✓

First-tier Tribunal categories — paper, basic, standard, and complex

The First-tier Tax Tribunal allocates appeals to one of four categories depending on the complexity of the issues and the amount of tax in dispute. Paper cases are determined on written submissions without a hearing; basic cases are heard without a formal exchange of evidence; standard cases involve a full hearing with evidence; and complex cases — the most significant appeals — involve exchange of witness statements, expert evidence, and full legal submissions. A solicitor will advise on the appropriate category for the specific appeal, manage the category application where the case is categorised incorrectly by the tribunal, and manage the exchange of evidence and submissions for the allocated category.

✓

Evidence and witness statements — building the factual case

Tax tribunal appeals are decided on the balance of probabilities — the tribunal will make findings of fact based on the documentary evidence and the witness evidence presented. A solicitor will identify the key facts in dispute, gather the documentary evidence that supports the taxpayer's case, and prepare witness statements that address the factual issues clearly and concisely. Where expert evidence is required — an independent valuation, an accountancy report, or a technical report on R&D or other specialist issues — a solicitor will commission and manage the expert instruction, ensuring the report is compliant with the tribunal's expert evidence directions and addresses the issues that the tribunal needs to decide.

✓

Settlement before the hearing — negotiating with HMRC

Most tax tribunal appeals settle before the hearing — the process of preparing for the tribunal focuses both parties' attention on the strength and weakness of their respective cases, and typically results in a negotiated resolution. A solicitor will assess the settlement value of the appeal — the range of outcomes at the tribunal and the cost of reaching it — and negotiate with HMRC's legal team (the Solicitor's Office and Legal Services, SOLS) to achieve the most favourable settlement before the hearing. Where settlement is not achieved, a solicitor will prepare the case fully and present it at the hearing. The tribunal may make an award of costs in complex cases where either party has acted unreasonably.

✓

The tribunal hearing — presenting the case

A First-tier Tribunal hearing is conducted before one or more judges (for complex cases, a judge and a non-legal member with relevant expertise). The hearing proceeds by way of opening submissions, witness evidence (examination in chief and cross-examination by HMRC's representative), closing submissions, and the tribunal's decision (which may be given immediately or reserved for a later date). A solicitor will manage all stages of the hearing — preparing the skeleton argument, presenting the opening and closing submissions, and cross-examining HMRC's witnesses. A well-presented case at the First-tier Tribunal significantly improves the prospects of success and sets the foundation for an Upper Tribunal appeal if needed.

Upper Tribunal appeals — challenging First-tier Tribunal decisions

An appeal from the First-tier Tribunal to the Upper Tribunal (Tax and Chancery Chamber) lies only on a point of law — not on the facts. Leave to appeal must be obtained from the First-tier Tribunal (or, if refused, from the Upper Tribunal). The Upper Tribunal is a superior court of record — its decisions bind the First-tier Tribunal and are cited in subsequent cases as precedent. Where the First-tier Tribunal has made an error of law — misapplied the legal test, reached a decision that no reasonable tribunal could have reached on the facts, or failed to give adequate reasons — a solicitor will advise on the prospects of a successful Upper Tribunal appeal and manage the appeal process.

How It Works

A tax tribunal appeal is litigation against HMRC — and litigation against HMRC requires the same legal skills and preparation as any other litigation. A solicitor manages every stage of the process to maximise the prospects of success.

A solicitor will manage the appeal from the notice of appeal through to the final hearing — preparing the grounds, managing the evidence, negotiating settlement with HMRC, and presenting the taxpayer's case at the tribunal hearing.

Common Questions

Tax tribunal appeals — what people ask us.

Do I have to pay the tax before I can appeal to the First-tier Tribunal?

No — you can apply to postpone payment of the disputed tax pending the outcome of the appeal. A postponement application is made to HMRC in the first instance (and to the tribunal if HMRC refuses). The tribunal will grant the postponement where there are reasonable grounds for the appeal — a relatively low bar. Where tax is postponed, HMRC cannot take enforcement action to collect it while the appeal is pending. Interest continues to accrue on the postponed tax during the appeal period — if the appeal is unsuccessful, the taxpayer pays the outstanding tax plus accrued interest. If the appeal succeeds, the tax liability is reduced or cancelled and no interest is payable on the cancelled element.

How long does a tax tribunal appeal take?

A First-tier Tribunal appeal typically takes 12–24 months from notification to hearing, depending on the complexity of the case and the tribunal's listing schedule. The initial stages — exchange of documents, witness statements, and expert reports — take approximately 6–12 months. The hearing itself may last from one day (simple cases) to several weeks (complex cases). After the hearing, the tribunal typically delivers its decision within 3–6 months. A solicitor will manage the timetable efficiently — meeting all tribunal directions on time, engaging with HMRC's legal team to narrow the issues in dispute, and settling the case before the hearing where the settlement terms are acceptable.

Can I recover my legal costs if I win at the First-tier Tribunal?

In most First-tier Tribunal cases, each party bears its own costs — the tribunal does not make costs awards in basic and standard cases. In complex cases (specifically designated as "complex" by the tribunal), the tribunal can make costs awards where a party has behaved unreasonably — either in the conduct of the proceedings or in its substantive legal position. A costs award in a complex case requires an application and a costs assessment. In the Upper Tribunal, costs are awarded more readily — the Upper Tribunal applies the standard civil courts costs rules, and a successful appellant is entitled to their costs unless the tribunal orders otherwise. A solicitor will advise on the prospects of a costs award and make any application where the tribunal's jurisdiction is engaged.

HMRC is appealing my successful First-tier Tribunal decision. What should I do?

Where HMRC appeals a First-tier Tribunal decision that was in the taxpayer's favour, the appeal proceeds to the Upper Tribunal on the ground that the First-tier Tribunal made an error of law. The taxpayer (now the respondent) is entitled to file a response to the appeal and to participate in the Upper Tribunal hearing. A solicitor will review HMRC's grounds of appeal, assess whether there is a good answer to the alleged error of law, and manage the Upper Tribunal proceedings — including the written submissions (skeleton arguments) and the oral hearing. The Upper Tribunal can dismiss the appeal (upholding the First-tier Tribunal's decision), allow the appeal (overturning it), or remit the case to the First-tier Tribunal for reconsideration.
