Tax Tribunal Appeals

Tax Tribunal Appeal Solicitors — First-tier Tribunal, Statutory Review, HMRC ADR, and Upper Tribunal

Where HMRC's decision is wrong — whether an income tax assessment, a corporation tax determination, a VAT decision, an IHT charge, or a PAYE liability — the First-tier Tribunal (Tax Chamber) provides an independent judicial forum to challenge it. A specialist tax tribunal solicitor manages the entire appeal process: notifying the appeal to HMRC within 30 days; requesting statutory review (TMA 1970 ss.49B–D) where available; pursuing HMRC ADR for suitable disputes; and preparing and running the Tribunal hearing — from the paper track through to the complex multi-day hearing. Where a First-tier Tribunal decision raises a point of principle, a further appeal lies to the Upper Tribunal (Tax and Chancery Chamber).

⚠️ The appeal deadline is 30 days from the HMRC decision — and it cannot be extended without a good reason. Most HMRC decisions (assessments, amendments, closure notices, penalty notices, determinations) must be appealed to HMRC — and then, if HMRC's review upholds the decision, to the First-tier Tribunal — within 30 days of the decision. A late appeal may be admitted where there is a good reason for the delay, but this is not guaranteed — a solicitor should be instructed before the 30-day deadline runs.

Tax Tribunal Appeals — Key Stages

📋
Notifying the appeal and requesting statutory review — TMA 1970 ss.49B–D — on receiving an HMRC decision the taxpayer wishes to challenge, the first step is to notify HMRC of the appeal (within 30 days of the decision — TMA 1970 s.49C). The taxpayer may then request a statutory review (TMA 1970 s.49B) — an internal HMRC review by a review officer who was not involved in the original decision. The review officer has 45 days to complete the review and issue a review conclusion letter. Statutory review is a prerequisite for appealing most HMRC decisions to the First-tier Tribunal. A solicitor manages the notification and statutory review process — preparing a detailed representations document for the review officer and tracking HMRC's 45-day deadline.
🤝
HMRC Alternative Dispute Resolution (ADR) — ADR is a facilitated mediation process run by a trained HMRC mediator (not involved in the enquiry) to help the taxpayer and HMRC case officer reach agreement on a dispute without going to the Tribunal. ADR is available for most tax disputes at any stage after HMRC has issued its decision — and can be requested by either the taxpayer or HMRC. ADR is particularly suitable where the dispute involves matters of fact (valuation, apportionment of costs between business and private use) rather than pure questions of law. A solicitor prepares the taxpayer's position paper for ADR, advises on what concessions are appropriate, and negotiates the agreed settlement. ADR does not prevent a subsequent Tribunal appeal if agreement cannot be reached.
⚖️
First-tier Tribunal (Tax Chamber) — four tracks — once statutory review is complete, the appeal may be notified to the First-tier Tribunal (Tax Chamber). The Tribunal allocates appeals to one of four tracks: Paper (suitable for straightforward appeals — decided on documents without a hearing); Basic (one-day hearing; simple legal issues or low-value disputes); Standard (multi-day hearing; most tax disputes — income tax, corporation tax, VAT, IHT, PAYE); and Complex (multi-day hearing with complex or novel legal issues). The standard and complex tracks involve significant preparation — witness statements, expert evidence, disclosure, and skeleton arguments. A solicitor manages the entire litigation process, instructs counsel for the hearing, and cross-examines HMRC's witnesses.
🔼
Upper Tribunal (Tax and Chancery Chamber) — a First-tier Tribunal decision may be appealed to the Upper Tribunal (Tax and Chancery Chamber) on a point of law only — i.e. the First-tier Tribunal made an error of law in its decision, not simply that the taxpayer disagrees with the factual findings. Permission to appeal must be obtained from either the First-tier Tribunal or the Upper Tribunal. The Upper Tribunal's decisions bind the First-tier Tribunal — making Upper Tribunal appeals particularly valuable where the First-tier Tribunal decision involves a legal point that could affect a significant number of taxpayers. A solicitor advises on whether a First-tier Tribunal decision contains an arguable error of law and manages the Upper Tribunal appeal process.
🛑
Postponement of tax pending appeal — where a taxpayer appeals an HMRC assessment, the tax may be postponed pending the outcome of the appeal if the taxpayer applies to HMRC (or, if HMRC refuses, to the First-tier Tribunal) for postponement of the tax charged by the assessment (TMA 1970 s.55). To obtain postponement, the taxpayer must show that there are reasonable grounds for the appeal — i.e. that the assessment is likely to be reduced or discharged on appeal. A solicitor advises on whether a postponement application is appropriate, prepares the grounds for postponement, and manages the Tribunal application where HMRC refuses. Without postponement, the tax is due on the statutory due date even while the appeal is pending — and interest runs on unpaid tax.
🔎
Judicial review of HMRC decisions — where HMRC's conduct is procedurally unlawful — exercising a power it does not have, failing to consider relevant matters, acting irrationally, or breaching a legitimate expectation — judicial review (JR) in the Administrative Court provides a remedy. JR is not an appeal on the merits (the Tax Tribunal hears the merits); it is a challenge to the lawfulness of HMRC's conduct. JR has strict time limits (generally 3 months from the date of HMRC's decision) and requires permission to proceed. A solicitor advises on whether HMRC's conduct is susceptible to JR, prepares the pre-action protocol letter, and manages the judicial review proceedings in the Administrative Court.

Frequently Asked Questions

What is the process for appealing an HMRC tax decision to the First-tier Tribunal?

The appeal process typically has four stages: (1) Notify HMRC of the appeal within 30 days of the decision — this is essential, and a late appeal requires a good reason; (2) Request statutory review (TMA 1970 s.49B) — an internal HMRC review by a review officer; HMRC has 45 days to complete the review; (3) If the review upholds HMRC's decision, notify the First-tier Tribunal of the appeal within 30 days of the review conclusion letter; (4) Tribunal proceedings — case management conference, exchange of documents and witness statements, Tribunal hearing, and decision. At any stage, HMRC ADR may be requested to resolve the dispute without a hearing. A solicitor manages each stage of the process and advises on the best route.

What is statutory review and do I have to request it before going to the Tribunal?

Statutory review (TMA 1970 s.49B) is an internal HMRC review of the decision by a review officer not involved in the original decision. It is not mandatory — a taxpayer may bypass statutory review and notify the appeal directly to the First-tier Tribunal (TMA 1970 s.49D). However, statutory review is often worthwhile: it is free, relatively quick (45 days), and may result in HMRC upholding the taxpayer's position without the time and cost of Tribunal proceedings. Where the dispute is primarily factual, a statutory review may result in a negotiated outcome. Where the dispute is a question of law, statutory review is less likely to produce a result — in those cases, notifying the Tribunal directly may be the better route. A solicitor advises on whether statutory review is the right approach for the specific dispute.

Can I have the tax on a disputed assessment postponed while the appeal is pending?

Yes — a taxpayer can apply to HMRC (or to the First-tier Tribunal if HMRC refuses) to postpone the tax charged by an assessment while the appeal is pending (TMA 1970 s.55). The taxpayer must apply for postponement and show reasonable grounds for the appeal. HMRC and the taxpayer agree the amount of tax to be postponed (typically the amount by which the taxpayer claims the assessment is excessive) — the agreed amount does not have to be paid until the appeal is determined. If HMRC disagrees with the postponement amount, the Tribunal determines the amount to be postponed. A solicitor advises on whether postponement is appropriate and prepares the grounds for the application.

Is HMRC ADR suitable for my tax dispute?

HMRC ADR is most suitable where the dispute involves factual matters — for example, valuation disputes, apportionment of expenses between business and private use, or disputes about the facts of a particular transaction. It is less suitable where the dispute turns entirely on a question of law, because the ADR mediator cannot bind either party on a legal point. ADR is not suitable where HMRC alleges fraud or deliberate conduct. ADR is confidential and without prejudice — anything said or offered in ADR cannot be referred to in subsequent Tribunal proceedings. Where ADR produces an agreed settlement, both sides sign a legally binding settlement agreement. Where agreement cannot be reached, the Tribunal appeal continues from where it left off. A solicitor advises on whether ADR is appropriate and prepares the position paper.

When can I appeal a First-tier Tribunal decision to the Upper Tribunal?

A First-tier Tribunal decision may be appealed to the Upper Tribunal (Tax and Chancery Chamber) on a point of law only — the First-tier Tribunal must have made an error of law in its decision. An error of law includes: misapplying the law to the facts; failing to give adequate reasons for its decision; taking into account irrelevant matters or failing to take into account relevant matters; or reaching a decision that no reasonable tribunal properly directing itself could have reached. Permission to appeal is required — the application must first be made to the First-tier Tribunal (within 56 days of the written decision), and if refused, to the Upper Tribunal itself. A solicitor advises on whether an arguable error of law exists and manages the Upper Tribunal proceedings.
