Executive Summary: Key Legal and Evidentiary Issues

• Jurisdiction of the Small Claims Division of the Court of Québec to hear a challenge to a tax interest assessment is the central threshold issue.
• Characterization of the taxpayer’s main argument as an attack on the very right of Agence du revenu du Québec (ARQ) to charge interest, rather than a mere dispute over calculation, removes the matter from Small Claims jurisdiction.
• Scope of article 93.2(d) of the Loi sur l’administration fiscale (LAF) is narrowed to contests dealing exclusively with the determination or calculation of interest or penalties, up to the statutory ceiling.
• Limits on the Court’s ability to refer the case from the Small Claims Division to the regular Division, due to the procedural rules in the Code de procédure civile (Cpc) governing tax matters, shape the outcome.
• Use of partial inadmissibility under article 168 Cpc is rejected because the two grounds of contestation are not sufficiently distinct and could both be brought before the regular Division in a single proceeding.
• Effect of an inadmissibility based on lack of jurisdiction is confirmed as not being a decision on the merits, leaving the taxpayer free to pursue the claim before the proper forum if desired.

Facts of the case

Allen Gottheil, a self-employed taxpayer, received a notice of assessment dated 5 April 2024 from Agence du revenu du Québec (ARQ) for the 2023 taxation year. The assessment claimed 174.09 CAD in interest for failure to make or adequately make required quarterly instalment payments (acomptes provisionnels). The taxpayer brought a proceeding before the Small Claims Division of the Court of Québec to contest this notice and sought the annulment of the interest claimed. Two distinct grounds were raised. First, he argued that the legislative and administrative scheme that imposes interest on self-employed individuals when they owe more than 1,800 CAD in tax due to insufficient instalments is discriminatory. In his view, self-employed taxpayers are treated less favourably than salaried employees who, in a comparable situation arising from insufficient source deductions, are not required to pay similar interest. Second, he claimed that even if interest were generally payable, the ARQ’s specific calculation of the amount owing in his case was wrong because it did not take proper account of the date on which his payment was received by the ARQ. The ARQ responded not by addressing the substance of these complaints, but by filing a motion for inadmissibility, arguing that the Small Claims Division did not have the legally conferred jurisdiction (compétence d’attribution) to hear the contestation on the grounds invoked by the taxpayer.

Legal framework and jurisdictional limits

The Court of Québec is a statutory court, and in tax matters it may only decide disputes for which jurisdiction is conferred by statute. The relevant framework is the Loi sur l’administration fiscale (LAF). That statute creates, in certain circumstances, a procedural option for taxpayers to challenge ARQ decisions by way of a Small Claims proceeding. Specifically, article 93.2(d) LAF allows a person to file a contestation in the Small Claims Division instead of using the regular tax appeal route, but only where the contestation relates exclusively to the determination of interest or penalties not exceeding 5,500 CAD. In other words, Small Claims jurisdiction in tax matters is exceptional and strictly delimited: it is available for relatively modest, arithmetic-type disputes about the amount of interest or penalties, not for broader attacks on the validity of the underlying statutory scheme or the right to levy interest at all. The Court emphasized that the Small Claims Division’s jurisdiction is therefore limited when it comes to the grounds on which interest can be contested. Challenges that go beyond calculation and strike at the lawfulness of the interest regime itself fall outside the scope of article 93.2(d) LAF. In addition, the Court considered whether the Small Claims Division could simply transfer the matter to the regular Division of the Court of Québec. This option was rejected because article 541(2)(2) Cpc only permits such a referral where the matter can be heard under the simplified rules specifically applicable to Small Claims. Tax contests before the regular Division, however, must proceed under the full contentious procedure governed by articles 141 to 301 Cpc, as required by the Loi sur les tribunaux judiciaires. This procedural incompatibility prevents a straightforward transfer from Small Claims to the regular Division.

Nature of the taxpayer’s grounds and partial inadmissibility

The Court then examined the two grounds of contestation advanced by the taxpayer. The first ground sought to have the interest cancelled on the basis that the differential treatment between self-employed workers and salaried employees is discriminatory and contrary to public order. The Court held that this ground goes to the very right of the ARQ to collect interest under the statutory scheme, and therefore exceeds the jurisdiction of the Small Claims Division under article 93.2(d) LAF. It is not a dispute about how much interest is owed; it is a dispute about whether interest can be charged at all in these circumstances. As such, this claim cannot be heard in Small Claims. By contrast, the second ground—alleging that the ARQ miscalculated the interest because it failed to account for the actual date the payment was received—does fall within the core of what Small Claims tax jurisdiction is designed to cover: a challenge to the calculation of interest rather than to the underlying entitlement to charge it. In principle, this second ground could be heard in Small Claims. Because of this, the Court considered whether it could apply the mechanism of partial inadmissibility under article 168 Cpc. That provision allows a court to declare a claim inadmissible in part where only some aspects are unfounded in law, in order to streamline the real issues in dispute and respect the principle of proportionality. The judge reflected on the role of Small Claims judges under article 560 Cpc, which is to give equitable and impartial assistance to both parties to bring out and enforce the law, and weighed whether it would be appropriate to reject only the first (jurisdictionally barred) ground while allowing the second (calculation-related) ground to proceed.

Reasons for rejecting partial inadmissibility

The Court ultimately decided against partial inadmissibility and instead declared the entire contestation inadmissible. Several reasons supported this outcome. First, resorting to partial inadmissibility would undermine proportionality in this context, because the taxpayer retains the possibility of re-introducing the whole dispute before the regular Division within the applicable prescription period. Continuing in Small Claims only on the calculation issue would fragment the litigation and potentially multiply proceedings rather than simplify them. Second, the two grounds of contestation were not considered sufficiently individualized and separable to justify rejecting one and preserving the other. The alleged discrimination and the alleged miscalculation both relate to the same interest amount and could be addressed together in a single proceeding before the regular Division. Third, the Court noted that nothing obliged the taxpayer to proceed in Small Claims for the calculation issue; the LAF simply offered this as an option, on the condition that the taxpayer accept to limit the debate strictly to the determination of interest. In this case, the taxpayer did not accept that limitation and chose to attack both the validity of the interest scheme and the calculation. Because both grounds could be heard together in the regular Division, and because of the constraints on Small Claims jurisdiction and transfers, the Court concluded that complete inadmissibility was the more coherent solution.

Outcome and effects of the judgment

In the result, the Court granted ARQ’s motion for inadmissibility, rejected the taxpayer’s contestation of the 5 April 2024 notice of assessment, and did so expressly on the basis of lack of jurisdiction of the Small Claims Division. The judge carefully specified that this dismissal is not a decision on the merits of the taxpayer’s claims, particularly as to whether the interest regime is discriminatory or whether the interest amount was properly calculated. The taxpayer therefore remains free, in principle, to bring an appropriate proceeding before the regular Division of the Court of Québec using the proper contentious tax procedure if he wishes to pursue both grounds. The judgment was rendered without costs (“le tout sans frais”), so no monetary award, damages, or costs were granted in favour of either party. The successful party in this decision is the Agence du revenu du Québec, but there was no specific monetary amount ordered or awarded in its favour beyond the fact that its interest assessment for 174.09 CAD remains in force, and the exact total of any enforceable monetary award or costs ordered by the Court in this judgment cannot be determined because none were expressly quantified.
