Carousel Schemes and Missing Trader Fraud in the Canadian GST/HST System

Carousel schemes, also referred to internationally as missing trader intra community fraud, represent one of the most sophisticated forms of indirect tax evasion. Although historically associated with the European value added tax system, the structural similarities between the Canadian GST/HST and VAT regimes make the Canadian system theoretically vulnerable to the same form of abuse. The essence of a carousel scheme lies in the manipulation of input tax credit entitlements through chains of transactions involving participants who collect tax but intentionally fail to remit it, thereby allowing other participants to claim refunds to which they are not legitimately entitled. This article examines the mechanics of carousel schemes in the Canadian GST/HST context, the legislative framework governing input tax credits, the jurisprudential tools available to the Canada Revenue Agency and the courts, and the policy considerations that arise when combating such fraud.

At the foundation of any carousel scheme lies the structure of value added taxation. The GST and HST operate on a credit invoice system in which tax is charged at each stage of the supply chain but businesses are entitled to recover tax paid on inputs used in commercial activities. Section 165 of the Excise Tax Act imposes the tax on taxable supplies made in Canada. Registrants who acquire property or services for use in commercial activity may claim input tax credits under section 169 to recover the tax paid on those inputs. The system functions efficiently when each participant properly reports and remits the net tax owing. However, the reliance on self assessment and the refundability of input tax credits creates an inherent vulnerability where fraudulent actors exploit the mechanism.

A carousel scheme typically involves a series of orchestrated transactions among multiple entities. The simplest version begins with a supplier that sells goods to a registrant and charges GST or HST on the transaction. The purchasing registrant claims the corresponding input tax credit. In a fraudulent arrangement, one participant in the chain acts as the “missing trader.” This entity charges tax on its sales but disappears without remitting the tax to the Canada Revenue Agency. Subsequent purchasers continue to claim input tax credits based on invoices that appear legitimate. In more elaborate structures, the goods are circulated through a chain of entities and eventually returned to the original supplier, allowing the process to repeat in a continuous “carousel” of transactions.

While Canadian jurisprudence does not frequently use the term carousel fraud, courts have encountered similar arrangements involving fictitious or circular trading designed to generate GST refunds. In such cases the central legal question is whether the taxpayer claiming input tax credits has satisfied the statutory requirements in section 169 of the Excise Tax Act. To claim an input tax credit, the registrant must have acquired the property or service for use in commercial activities and must possess prescribed documentary evidence under the Input Tax Credit Information (GST/HST) Regulations. Where transactions are fabricated or the documentation is unreliable, the entitlement to credits fails.

Canadian courts have consistently emphasized that the burden rests on the taxpayer to establish the factual foundation of the credit claim. In Systematix Technology Consultants Inc v Canada, 2007 FCA 226, the Federal Court of Appeal confirmed that the taxpayer must demonstrate that the supply actually occurred and that tax was payable in respect of that supply. The court rejected the notion that the mere possession of invoices is sufficient where the surrounding circumstances indicate that the transactions lacked economic reality. Similarly, in Global Cash Access (Canada) Inc v Canada, 2013 FCA 269, the Federal Court of Appeal reaffirmed that input tax credits are strictly statutory entitlements and cannot be claimed unless the legislative requirements are fully satisfied.

Where carousel type fraud is suspected, the Canada Revenue Agency typically challenges input tax credit claims on several grounds. The first involves establishing that the alleged supplies did not occur in fact. If the CRA demonstrates that the goods were never delivered or the transactions were fictitious, the taxpayer cannot satisfy the statutory requirement that tax became payable in respect of a supply. Courts often examine commercial documentation, banking records, transportation evidence and witness testimony to determine whether the transactions were genuine.

A second approach involves the application of the doctrine of sham. A sham arises where parties create documents or legal structures intended to give the appearance of transactions that differ from the true legal relationships among them. The Supreme Court of Canada in Stubart Investments Ltd v Canada, [1984] 1 SCR 536, explained that a sham requires a deliberate attempt to deceive third parties or the court regarding the legal rights and obligations created by the documentation. In the GST context, if invoices or contracts are issued solely to fabricate entitlement to input tax credits while the parties understand that no genuine supply exists, the arrangement may be characterized as a sham and disregarded.

Another analytical tool available to the CRA is the general anti avoidance rule in section 274 of the Excise Tax Act. Although GAAR is more frequently applied in income tax cases, it can also be invoked where a transaction results in a misuse or abuse of the GST/HST provisions. The Supreme Court of Canada’s GAAR framework articulated in Canada Trustco Mortgage Co v Canada, 2005 SCC 54, and Copthorne Holdings Ltd v Canada, 2011 SCC 63, requires the Crown to demonstrate that the transaction results in a tax benefit, that the transaction is avoidance in nature, and that it frustrates the object, spirit and purpose of the legislation. In a carousel scheme the artificial generation of refundable input tax credits without corresponding tax remittance could potentially constitute such an abuse.

Canadian courts also examine the knowledge and conduct of the taxpayer claiming the credits. Although the Excise Tax Act does not expressly impose a due diligence requirement on purchasers claiming input tax credits, courts have been attentive to circumstances where the claimant knew or ought to have known that the transactions formed part of a fraudulent arrangement. In several Tax Court cases involving GST refund schemes, judges have noted that commercially implausible transactions, unusual payment methods, or the absence of basic business records may undermine the credibility of the taxpayer’s position. The analysis often turns on whether the taxpayer can demonstrate that it was genuinely engaged in commercial trading rather than participating knowingly in a circular scheme.

From an enforcement perspective, carousel schemes pose significant administrative challenges. The fraud relies on rapid movement of goods and the use of multiple corporate entities, often with limited assets or short operational lifespans. Once the missing trader disappears, the government may face substantial refund claims from downstream participants who appear on paper to have legitimate entitlement to input tax credits. The CRA must therefore investigate complex transaction chains and gather evidence across multiple parties in order to reconstruct the true economic activity.

International experience demonstrates the scale of potential losses from carousel fraud. In the European Union, missing trader schemes have resulted in billions of euros in lost VAT revenue. These experiences have influenced Canadian tax authorities to monitor industries characterized by high value portable goods such as electronics, precious metals and carbon credits, which historically have been common vehicles for carousel fraud abroad.

Policy discussions regarding carousel schemes in Canada often focus on balancing fraud prevention with the integrity of the credit invoice system. The GST/HST regime is designed to be neutral and to avoid imposing tax costs on businesses engaged in legitimate commercial activity. Overly restrictive rules governing input tax credits could undermine that neutrality and create administrative burdens for honest taxpayers. Consequently, Canadian law generally relies on case by case factual analysis rather than imposing broad statutory restrictions on credit claims.
