# MTIC Accusations: Your Rights and HMRC’s Burden of Proof

Receiving a letter from HM Revenue & Customs alleging involvement in Missing Trader Intra-Community (MTIC) fraud, sometimes called carousel fraud, is one of the most alarming experiences a business can face. HMRC does not need to prove that a company orchestrated the fraud. It only needs to persuade a tribunal that the company knew, or should have known, that its transactions were connected to VAT fraud elsewhere in the supply chain. That lower threshold catches a significant number of entirely legitimate businesses, particularly those trading in mobile phones, computer processing units, and other high-value, easily transportable goods.

This article explains what an MTIC accusation actually involves, the legal test HMRC must satisfy, the burden of proof that rests on HMRC's shoulders (not yours), and the steps a business should take to protect itself. If you have received an extended verification letter, a Notice 726, or a VAT assessment denying your right to deduct input tax, understanding your rights at the outset can make the difference between a swiftly resolved dispute and a protracted, expensive fight before the [First-Tier Tax Tribunal](https://taxdisputes.co.uk/first-tier-tax-tribunal-solicitors-london/).

### What Is an MTIC Accusation?

[Missing Trader Intra-Community fraud](https://taxdisputes.co.uk/missing-trader-fraud-vat-evasion-solicitors-london/) exploits the VAT rule that cross-border trade within the EU is zero-rated. A fraudulent "missing trader" imports goods VAT-free, sells them on within the UK inclusive of VAT, then disappears without ever accounting for that VAT to HMRC. The goods are frequently passed through a chain of intermediate businesses, referred to as buffers, before being exported again, sometimes back to the original overseas supplier, in what becomes a repeating "carousel" of transactions.

The individuals behind the missing trader are usually long gone by the time HMRC investigates. What remains are the other companies in the chain, the buffers and exporters, who bought and sold the goods in good faith and have no knowledge that fraud occurred several steps removed from their own dealings. It is these innocent businesses that HMRC most often pursues, because they are traceable and solvent, while the fraudsters themselves are not.

An MTIC accusation typically surfaces through an extended verification exercise, a visit under Notice 726, or a formal decision letter denying input tax and raising a VAT assessment. Businesses caught in the middle of a supply chain, particularly those dealing in mobile phones, CPUs, and similar commodities, are especially exposed. For more on how HMRC approaches VAT enforcement generally, see our guidance on [HMRC VAT investigations](https://taxdisputes.co.uk/hmrc-vat-investigations-evasion-input-ouput-double-taxation-tribunal-legal-advice/).

### The Legal Test: Kittel and Mobilx

The legal foundation for denying input tax in MTIC cases comes from the European Court of Justice's decision in [Axel Kittel v Belgian State and Belgian State v Recolta Recycling SPRL (C-439/04 and C-440/04)](https://curia.europa.eu/juris/liste.jsf?language=en&num=439/04). The Court held that where it is objectively established that a taxable person knew or should have known that, by their purchase, they were participating in a transaction connected with VAT fraud, the right to deduct input tax must be refused, even where the transaction itself satisfied the objective criteria of a supply for VAT purposes.

This principle, now widely known as the "Kittel test", was applied and refined by the Court of Appeal in [Mobilx Ltd (in administration) v Revenue and Customs Commissioners [2010] EWCA Civ 517](https://www.bailii.org/ew/cases/EWCA/Civ/2010/517.html). The Court confirmed that a trader loses the right to deduct input tax if it knew or should have known that the transaction in question was connected with fraudulent evasion of VAT. Importantly, the Court held that the test is not confined to actual knowledge of the specific fraud. A trader who has the means of knowledge available and chooses not to ask the obvious questions can be treated as having constructive knowledge.

Mobilx also made clear that undue emphasis should not be placed on whether a business carried out due diligence as a standalone exercise. The tribunal must instead look at the whole picture: what a trader actually knew, what a reasonable business in that position ought to have suspected, and whether the only reasonable explanation for the circumstances of the transaction was that it was connected to fraud. This is a fact-sensitive, holistic assessment, not a tick-box exercise measured against a due diligence checklist.

### HMRC's Burden of Proof

This is the point that many businesses misunderstand, and it is the single most important principle to grasp when responding to an MTIC accusation. HMRC bears the burden of proving, on the balance of probabilities, both:

- That there was a tax loss, and that loss resulted from fraudulent evasion; and

- That the trader's own transaction was connected with that fraudulent evasion, and that the trader knew or should have known of that connection.

It is not for a business to prove its innocence. HMRC must build an evidential case, tracing the supply chain back to the point of the tax loss and establishing the connection to the fraud. In practice, HMRC often relies on inference: unusual pricing, an absence of commercial risk, sudden willingness of unknown counterparties to trade in large volumes, or payment instructions that make no ordinary commercial sense. None of this is automatically sufficient. Each piece of evidence must be weighed by the tribunal, and a business is entitled to put forward an alternative, innocent explanation for its conduct.

Where HMRC's case rests heavily on generalised "badges of fraud" rather than evidence specific to your transactions, that is often a sign the assessment can be successfully challenged. Our [HMRC tax appeals](https://taxdisputes.co.uk/hmrc-tax-appeals-solicitors-london/) team regularly tests whether HMRC has, in fact, discharged this burden, and in a substantial number of cases it has not.

### Constructive Knowledge: What "Should Have Known" Really Means

The phrase "knew or should have known" causes considerable anxiety among honest traders, because it can sound as though any oversight is enough to lose the case. That is not correct. The test requires HMRC to show that the only reasonable explanation for the circumstances of the specific transaction was that it was connected with fraud. Carelessness, a missed red flag, or an imperfect due diligence file is not, by itself, the same as constructive knowledge.

Tribunals will typically examine:

- Whether the pricing and profit margin were commercially realistic

- The trading history and financial standing of the immediate supplier and customer

- Whether payment instructions followed a normal commercial pattern

- Whether the goods, their movement, and the documentation were consistent with a genuine commercial transaction

- Whether the trader made reasonable enquiries when something appeared unusual

If your business can demonstrate that it operated as any prudent trader in that market would, checking VAT registration numbers, verifying company details, querying inconsistencies, and maintaining contemporaneous records of those checks, this evidence carries real weight before the tribunal.

### The Consequences of an MTIC Accusation

The immediate consequence of an adverse HMRC decision is usually a VAT assessment denying input tax that has already been reclaimed, often running into hundreds of thousands or even millions of pounds. HMRC may also move to deregister the business for VAT, which can be separately challenged, and in more serious cases will pursue [penalties](https://taxdisputes.co.uk/hmrc-penalties/) of up to 30% of the tax at stake under the penalty regime introduced by section 68 of the Finance (No.2) Act 2017.

Where a business cannot satisfy the resulting liability, HMRC can and does escalate to enforcement action, including the presentation of a [winding-up petition](https://windinguppetitionsolicitors.co.uk/opposing-a-winding-up-petition/) against the company. Once a petition is advertised in the London Gazette, banks will typically freeze the company's accounts, which can be commercially fatal even before the underlying VAT dispute has been resolved. Businesses facing this situation should take immediate advice on obtaining a [validation order](https://windinguppetitionsolicitors.co.uk/validation-order/) to unfreeze trading accounts, or on setting aside a [statutory demand](https://windinguppetitionsolicitors.co.uk/statutory-demand-set-aside-lawyers-london-hmrc/) before a petition is presented at all. In genuinely disputed cases, a winding-up petition can often be resisted on the basis that the underlying debt is disputed on substantial grounds.

In the most serious cases, HMRC's Fraud Investigation Service may also consider criminal referral to the Revenue and Customs Prosecutions Office, particularly where there is evidence of actual, rather than constructive, knowledge. Early legal advice is essential to keep a civil dispute from escalating into a criminal one.

### Protecting Your Business: Evidence and Due Diligence

Because HMRC's case in MTIC disputes is built almost entirely on inference from surrounding circumstances, the quality of your own contemporaneous evidence is decisive. Businesses trading in sectors HMRC associates with MTIC fraud should maintain:

- Verification of trading partners' VAT registration numbers and company status via [Companies House](https://www.gov.uk/government/organisations/companies-house) and HMRC's VIES checker

- Records of credit checks and financial standing enquiries

- Written notes of any commercial concerns raised, and the answers received

- Evidence of market-standard pricing and realistic profit margins

- Consistent, traceable payment instructions matching the counterparty on the invoice

None of this guarantees immunity from an HMRC challenge, but a well-documented due diligence trail significantly strengthens a business's position if HMRC later alleges constructive knowledge, and it demonstrates to a tribunal that the business behaved as a careful trader would.

### Challenging HMRC's Decision

If HMRC has issued an assessment or a decision denying input tax, a business generally has 30 days to request an internal review or lodge an appeal with the [First-Tier Tax Tribunal](https://taxdisputes.co.uk/first-tier-tax-tribunal-solicitors-london/). Missing this deadline does not necessarily end matters, as [late appeals](https://taxdisputes.co.uk/late-hmrc-tax-appeals/) can sometimes still be admitted, but early action gives a business the best chance of a favourable outcome and avoids the compounding pressure of accruing interest and enforcement risk.

Appeals in MTIC cases are document and evidence heavy, frequently involving voluminous transaction bundles, expert evidence on industry practice, and detailed cross-examination of HMRC's investigating officer. Where HMRC's decision appears disproportionate or procedurally flawed, [judicial review](https://taxdisputes.co.uk/judicial-review-applications-against-hmrc-challenge-decision-advice/) may also be available as a separate avenue of challenge.

### Where an Accountant's Advice Made Things Worse

Some businesses find themselves in this position partly because an accountant failed to flag obvious warning signs, gave poor guidance on due diligence, or missed an appeal deadline that has since made resolution far harder. Unlike solicitors and barristers, accountants owe no duty of confidentiality and their communications are not protected by legal professional privilege, meaning anything you have told your accountant can, in principle, be obtained by HMRC. Where negligent advice has caused or worsened your loss, a separate claim may be available against the [negligent adviser](https://professionalnegligenceclaimsolicitors.co.uk/compensation-negligent-accountants-financial-tax-advisors/).
