Tax Tribunal Appeals: How to Prepare Your Bundle

Last updated: March 2026

Quick Answer

A tax tribunal appeal bundle is the organised collection of documents you submit to the First-tier Tribunal (Tax Chamber) when challenging an HMRC decision. Your bundle must include the notice of appeal, the HMRC decision letter, your grounds of appeal, any relevant correspondence, and supporting evidence. The Tribunal Procedure (First-tier Tribunal) (Tax Chamber) Rules 2009 govern the process, and getting your bundle right can make the difference between winning and losing your appeal.

What Is the First-tier Tribunal (Tax Chamber)?

The First-tier Tribunal (Tax Chamber) is the independent judicial body that hears appeals against decisions made by HMRC. It sits within the unified tribunal system established by the Tribunals, Courts and Enforcement Act 2007 and handles a wide range of tax disputes — from income tax assessments and VAT penalties to National Insurance contributions and tax credit overpayments.

Unlike the county court or family court, the tax tribunal operates under its own procedural rules and has its own distinct culture. It is designed to be accessible to unrepresented taxpayers, and many appellants do appear without professional representation. That said, the tribunal takes evidence and procedure seriously, and a well-prepared bundle signals to the judge that you have taken your case seriously too.

What Kinds of Decisions Can You Appeal?

You can appeal to the First-tier Tribunal (Tax Chamber) against a range of HMRC decisions, including:

• Income tax assessments — where HMRC has assessed you for additional tax
• Corporation tax determinations — assessments raised against limited companies
• VAT assessments and penalties — including default surcharges and late filing penalties
• PAYE coding notices — where your tax code is wrong and HMRC will not correct it
• Tax credit decisions — overpayments, entitlement disputes, and penalties
• National Insurance contributions — disputes about liability or categorisation
• Penalty assessments — for late filing, late payment, inaccuracies, or failure to notify
• Closure notices — following an HMRC enquiry into your tax return
• Information notices — in limited circumstances, you can appeal an HMRC information notice

Not every HMRC decision carries a right of appeal. The decision letter itself should tell you whether you can appeal and the time limit for doing so.

Before You Appeal: The HMRC Review Process

Before lodging a tribunal appeal, you should understand the two-stage process that HMRC operates.

Stage 1: Internal Review

When HMRC makes a decision you disagree with, you can ask for an internal review. This is a fresh look at the decision by a different HMRC officer who was not involved in the original decision. You normally have 30 days from the date of the decision letter to request a review.

The review officer will examine the facts, the law, and the original officer's reasoning. They can uphold the decision, vary it, or cancel it entirely. HMRC aims to complete reviews within 45 days, though complex cases may take longer.

Stage 2: Tribunal Appeal

If the review upholds the decision — or if you prefer to skip the review and go straight to the tribunal — you can lodge a formal appeal. The time limit is usually 30 days from the date of the decision letter, or 30 days from the date of the review conclusion letter if you requested a review.

If you miss the deadline, you can apply for permission to appeal late, but you will need to explain why the delay occurred and the tribunal has discretion to refuse.

Which Route Should You Choose?

In practice, most advisers recommend requesting a review first. If HMRC concedes, you avoid the stress and preparation of a tribunal hearing entirely. If they do not, you have lost only a few weeks.

Grounds of Appeal: Getting the Foundation Right

Your grounds of appeal are the heart of your case. They set out precisely why you believe HMRC's decision is wrong — whether on the facts, the law, or both.

What Makes Strong Grounds of Appeal?

Strong grounds of appeal are specific, evidence-based, and legally coherent. They should:

1. Identify the decision being appealed — quote the reference number and date
2. State the legal basis for your appeal — which provision of tax law applies
3. Explain why the decision is wrong — on the facts, the law, or both
4. Reference supporting evidence — point to documents that support your position
5. State the outcome you are seeking — cancellation of the assessment, reduction of the penalty, or other relief

Common Grounds of Appeal

What to Avoid

Weak grounds of appeal include:

• "I disagree with HMRC" without explaining why
• Arguments based on personal hardship alone (unless relevant to a penalty reasonable excuse defence)
• Political objections to the tax system
• Grounds that have already been rejected by higher courts

Preparing Your Bundle: What to Include

The tribunal will expect a paginated, indexed bundle containing all the documents both parties intend to rely upon at the hearing. In many cases, the tribunal will issue directions specifying how the bundle should be prepared and when it must be filed.

Core Bundle Contents

Your bundle should typically include the following sections, in this order:

Formatting Requirements

The First-tier Tribunal does not have a single practice direction equivalent to PD27A in family proceedings. However, the tribunal expects bundles to be:

• Paginated consecutively — every page numbered sequentially throughout the bundle
• Indexed — with a table of contents at the front listing each document and its page number
• Logical — documents arranged in chronological or thematic order
• Legible — all documents must be readable, with poor-quality copies replaced where possible
• Cross-referenced — witness statements should reference bundle page numbers

Electronic bundles are now standard in the tax tribunal. PDF bundles should include bookmarks for each document and be text-searchable (OCR processed).

The Hearing: What to Expect

Tax tribunal hearings range from simple paper determinations to multi-day oral hearings, depending on the complexity of the case.

Categories of Case

You have the right to request an oral hearing even in default paper cases, and it is usually worth doing so. A hearing gives you the chance to explain your case in your own words and to respond to the judge's questions.

On the Day

The hearing will typically proceed as follows:

1. Introduction — the judge outlines the issues and confirms the parties are ready
2. HMRC's case — HMRC presents its position first, as the decision-maker
3. Your case — you present your case, referring to documents in the bundle
4. Questions — the judge may ask questions of both parties
5. Closing submissions — each party summarises its position
6. Decision — the judge may give a decision on the day or reserve it for later

Practical Tips for the Hearing

• Know your bundle — you should be able to find any document quickly by page number
• Prepare a skeleton argument — a short written summary of your legal arguments
• Be concise — judges appreciate focused submissions
• Answer questions directly — do not evade or speculate
• Remain professional — even if you disagree with HMRC's position, keep your tone measured

Common Mistakes in Tax Tribunal Appeals

Having seen many tribunal bundles, certain mistakes recur frequently:

1. Missing the deadline — the 30-day time limit is strictly enforced, and late appeals are regularly refused
2. Vague grounds of appeal — "I disagree" is not a ground of appeal
3. Failing to engage with HMRC's case — your grounds should address HMRC's reasoning directly
4. Poor bundle organisation — unpaginated, unindexed bundles irritate judges and weaken your credibility
5. Including irrelevant documents — a 500-page bundle for a £2,000 penalty appeal is excessive
6. Not requesting a hearing — paper determinations can go against you without the chance to explain
7. Ignoring directions — the tribunal's case management directions are not optional

Frequently Asked Questions

How long do I have to appeal to the tax tribunal?

You normally have 30 days from the date of the HMRC decision letter, or 30 days from the date of the review conclusion letter if you requested an internal review. If you miss the deadline, you can apply for late permission, but the tribunal may refuse.

Do I need a solicitor or accountant to appeal?

No. The First-tier Tribunal (Tax Chamber) is designed to be accessible to unrepresented taxpayers, and many people successfully appeal without professional help. However, for complex or high-value disputes, professional advice can be valuable.

How much does it cost to appeal to the tax tribunal?

There is currently no fee to lodge an appeal with the First-tier Tribunal (Tax Chamber). This is one of the few courts and tribunals in England and Wales that does not charge a filing fee.

What happens if I lose?

If the tribunal dismisses your appeal, HMRC's decision stands and you will need to pay the tax or penalty assessed. You may be able to appeal further to the Upper Tribunal (Tax and Chancery Chamber), but only on a point of law — not simply because you disagree with the factual findings.

Can HMRC settle before the hearing?

Yes. HMRC can agree to settle a case at any stage, including after the appeal has been lodged. Settlement discussions are common, and many cases resolve without a hearing through what is called an "alternative dispute resolution" (ADR) process.

What is the burden of proof?

In most tax appeals, the burden of proof lies with the taxpayer. This means you must demonstrate, on the balance of probabilities, that HMRC's decision is wrong. There are exceptions — for example, in penalty cases, HMRC bears the burden of proving that the conditions for imposing a penalty are met.

Can I claim costs if I win?

The First-tier Tribunal does not normally award costs in tax cases. However, the tribunal can make a costs order if a party has acted unreasonably in bringing, defending, or conducting the proceedings. In complex category cases, different costs rules may apply.
