Businesses that are forcibly [de-registered](https://taxdisputes.co.uk/appeal-hmrc-vat-de-registration-cancel-number-taxable-goods-supplies-kittel-decision-letter-judicial-review-legal-advice/) face immediate, tangible commercial consequences: they can no longer issue VAT-bearing invoices, they lose the right to reclaim input tax on purchases, and they risk being hit with substantial retrospective assessments. For many businesses, particularly those operating in VAT-sensitive sectors, it can be commercially crippling. The good news is that a decision by HMRC to cancel your VAT number is not final. There is a clear, two-stage legal process to challenge the decision, but strict time limits apply, and the consequences of missing them can be fatal to any appeal. This guide explains your rights, the grounds on which HMRC typically acts, how to challenge the decision effectively, and why you should seek [specialist legal advice](https://lexlaw.co.uk/) without delay. ## Why HMRC Cancels VAT Registrations HMRC's power to cancel a VAT registration is found in [paragraph 13 of Schedule 1 to the Value Added Tax Act 1994 (VATA 1994)](https://www.legislation.gov.uk/ukpga/1994/23/schedule/1). There are two primary grounds on which HMRC exercises this power: ### 1. Cessation of Taxable Supplies HMRC may de-register a business if it concludes, following an [investigation](https://taxdisputes.co.uk/hmrc-tax-investigations/) or a review of filed returns, that the business is no longer making, or does not intend to make, taxable supplies. This is the most straightforward basis. A business may contest this ground by demonstrating that taxable supplies continue or are genuinely intended. ### 2. Fraud or Fraudulent Intent In more serious cases, HMRC may cancel a VAT registration on the basis that it was obtained, or is being used, principally to facilitate [fraud on the VAT system](https://taxdisputes.co.uk/repayment-fraud/). These cases frequently arise in sectors historically associated with [Missing Trader Intra-Community (MTIC) fraud](https://lexlaw.co.uk/practice-areas/taxation-solicitors-london/vat-appeals-mtic-solicitors-london/), such as mobile phones, CPUs, and carbon credits. Where fraud is alleged, the burden of proof lies with HMRC. It must establish that fraudulent activity has occurred, or that the taxpayer knew, or ought to have known, that its transactions were connected to fraud. [HMRC's decision letter](https://taxdisputes.co.uk/2026/03/received-an-hmrc-letter-what-to-do-next/) will typically be brief and lacking in detail. Deregistration is ordinarily the culmination of months of investigation. Receiving the letter is often the first moment a business owner becomes aware of the full scale of HMRC's position. That is why [early specialist advice](https://lexlaw.co.uk/practice-areas/) is indispensable, you need to understand the specific basis for HMRC's decision before you can mount an effective challenge. ## The Two-Stage Appeal Process The appeal framework for VAT de-registration decisions is governed by [section 83(1) of VATA 1994](https://taxdisputes.co.uk/2020/10/hmrc-assessments-penalties-vat-appeal-to-first-tier-tax-tribunal-out-of-time-late-advice/) and the [Tribunal Procedure (First-tier Tribunal) (Tax Chamber) Rules 2009 (SI 2009/273)](https://www.gov.uk/hmrc-internal-manuals/appeals-reviews-and-tribunals-guidance/artg3041). There are two principal stages. ### Stage 1: Notice of Appeal to HMRC The first step is to give written notice of appeal to HMRC within 30 days of the date of their decision notice. This is not simply a letter of complaint, it is a formal legal step that triggers HMRC's obligation to reconsider. HMRC will then either: confirm their original decision; amend it in light of the representations made; or agree with the taxpayer's position in full. At this stage, HMRC may also offer, or the taxpayer may request, an [HMRC internal review](https://taxdisputes.co.uk/hmrc-internal-review-appeals-solicitors-london/). This is a statutory process under which a different HMRC officer (not the original decision-maker) considers whether the decision was made in accordance with HMRC's own guidelines. Internal reviews have a strong track record: published HMRC statistics have shown that approximately 49% of internal reviews result in HMRC's decision being annulled or amended. That figure alone makes it a procedure worth pursuing. ### Stage 2: Appeal to the First-tier Tax Tribunal (FTT) If the internal review does not resolve the dispute, the taxpayer may appeal to the [First-tier Tax Tribunal](https://lexlaw.co.uk/first-tier-tax-tribunal-hmrc-representation-solicitor-london/) under section 49D of the Taxes Management Act 1970. For VAT (an indirect tax), an appeal can be made directly to the FTT without first exhausting the HMRC internal process, though it is generally advisable to use it. The FTT is entirely independent of HMRC and is governed by an overriding objective to deal with cases fairly and justly (Rule 2, First-tier Tribunal Rules 2009). It will consider the evidence of both parties, including witness statements and documentary evidence, and will apply relevant case law. The Tribunal's jurisdiction in de-registration cases is, in part, a full appellate jurisdiction: where the issue is whether the taxpayer is still making taxable supplies, the Tribunal decides that question on the facts for itself, it is not limited to asking whether HMRC's decision was reasonable (see [*David Love Marketing Ltd v HMRC* [2015] UKFTT 506 (TC))](https://www.bailii.org/uk/cases/UKFTT/TC/2015/TC04664.html). Where, however, the decision involves the exercise of a discretion, for example, the precise date from which de-registration takes effect, the Tribunal's jurisdiction may be supervisory rather than full appellate. In those circumstances, the Tribunal considers whether HMRC acted reasonably and in accordance with the correct principles. ## Practical Steps to Challenge Your De-Registration Mounting a successful appeal requires careful preparation and an understanding of the evidence HMRC will rely upon. Set out below are the key practical steps. - **Read the decision letter carefully.** HMRC's letter will set out the ground for de-registration and should include instructions on how to appeal. Identify the precise statutory basis relied upon, whether it is paragraph 13(2)(a) (cessation of taxable supplies) or paragraph 13(2)(c) (fraud). - **Act within 30 days.** The appeal notice must be given in writing within 30 days. Whilst the FTT has a discretion to admit late appeals in exceptional circumstances (particularly following [*Medpro Healthcare Ltd v HMRC* [2025] UKUT 255 (TCC)](https://taxdisputes.co.uk/2025/10/medpro-v-hmrc-revised-tribunal-principles-on-late-vat-appeals/), which relaxed the previously strict [*Martland* test](https://lexlaw.co.uk/solicitors-london/late-hmrc-tax-tribunal-appeals-medpro-martland-your-options/)), you should never rely on that discretion. Late appeals are uncertain and expensive. - **Preserve and collate your evidence.** Gather all trading records, contracts, invoices, bank statements, and correspondence with suppliers or customers that demonstrate your business continues to make taxable supplies. If the fraud ground is relied upon, evidence of your due diligence and supply chain practices will be essential. - **Request an internal review if appropriate.** If you have not already received a review offer, you may request one at any time whilst the appeal is live. Given the near-50% amendment rate, it is often a cost-effective first step. - **Consider judicial review.** In some cases, particularly where HMRC has acted procedurally unfairly or where the decision was disproportionate, [judicial review](https://lexlaw.co.uk/hmrc-vat-de-registration-tax-appeal-kittel-decision-input-tax-decision-letter-judicial-review-legal-advice/) may be available as an alternative or supplementary remedy. A claim must be brought promptly and no later than three months after the grounds arose (CPR 54.5(1)). Proportionality arguments, including under the European Convention on Human Rights and section 6(1) of the Human Rights Act 1998, may carry weight where a business continues to make lawful taxable supplies. - **Instruct specialist legal representation.** VAT de-registration appeals are technically complex and evidentially demanding. Self-representation carries significant risk of procedural error and lost arguments. Specialist [tax dispute solicitors](https://taxdisputes.co.uk/appeal-hmrc-vat-de-registration-cancel-number-taxable-goods-supplies-kittel-decision-letter-judicial-review-legal-advice/) can assess the merits of your case, draft the notice of appeal, prepare witness statements, and provide advocacy at Tribunal. ## Key Legal Arguments in De-Registration Appeals The following arguments are commonly deployed in de-registration appeals and have found favour with the Tax Tribunal: ### Continuation of Taxable Supplies Where HMRC asserts that taxable supplies have ceased, a taxpayer can adduce evidence to demonstrate trading activity continues, or that there is a genuine, credible intention to resume. The FTT will determine this question on the evidence, not simply defer to HMRC's assessment. ### Challenging the Fraud Allegation Fraud is a serious accusation and HMRC must be put to strict proof. The standard is the civil standard of the balance of probabilities, but the seriousness of the allegation demands cogent evidence. HMRC must demonstrate either that the trader was party to fraudulent conduct, or that — applying the Kittel principle — it knew or should have known its transactions were connected to VAT fraud. Robust due diligence records can rebut this allegation significantly. LEXLAW has [succeeded before the Tax Tribunal](https://lexlaw.co.uk/practice-areas/taxation-solicitors-london/vat-appeals-mtic-solicitors-london/) in multiple high-value Kittel cases where HMRC failed to meet this burden. ### Proportionality and Human Rights Cancelling the VAT registration of a business that continues to make legitimate taxable supplies may be disproportionate. Arguments grounded in proportionality, and, where relevant, in the right to peaceful enjoyment of possessions under Protocol 1, Article 1 of the European Convention on Human Rights, have been successfully raised in VAT enforcement contexts. Where HMRC's decision is excessive relative to any legitimate aim, this ground can supplement a substantive appeal. ## Consequences of Inaction: What Happens If You Do Not Appeal Failing to appeal within the 30-day deadline, and failing to engage with either the internal review or the FTT, has serious and largely irreversible consequences. Under section 54 of the Taxes Management Act 1970, if a taxpayer neither accepts the review nor notifies an appeal to the Tax Tribunal, the dispute is treated as settled in HMRC's favour. It is then very difficult, and often impossible, to resile from that position. The business will be left without a VAT number, unable to recover input tax, and potentially exposed to retrospective assessments and [tax penalties](https://lexlaw.co.uk/hmrc-tax-penalty-appeal-solicitor-london/) for previous returns. If your business is the subject of a [winding-up petition](https://windinguppetitionsolicitors.co.uk) by HMRC or a creditor arising from the tax debt connected to de-registration, legal advice should be sought immediately. These two proceedings can interact in ways that make strategic coordination essential. ## Speak to a Specialist VAT Appeals Solicitor Today LEXLAW Solicitors & Barristers are specialist litigation solicitors based at Middle Temple, London.
