Taxation and Finance Quebec 3 Minutes Read · published February 11, 2026 Flag of Quebec · By Daniel Roy

Montréal, Quebec retailers must collect federal GST and provincial QST when selling taxable goods and services in the city. GST is levied at 5% and QST at 9.975% for most taxable supplies[1][2]. At the municipal level, retailers should also confirm licences and local obligations with the City of Montréal for premises, signage and business licences[3].

Check registration thresholds and effective dates before you start collecting taxes.

Penalties & Enforcement

Sales taxes in Québec are administered by two levels: the Canada Revenue Agency enforces GST and Revenu Québec enforces QST, while the City of Montréal enforces municipal bylaw requirements for licences and local rules. Interest and penalties for late remittance, reporting errors, or failure to register are applied by CRA and Revenu Québec according to their respective programs; consult those agencies for specific calculation methods and rates[1][2].
