    Montreal Tax Landscape

    Here's what you should know about taxes in Montreal, Quebec.

    Quebec QST (9.975%)

    Montreal businesses collect 9.975% QST in addition to 5% GST — Quebec administers its own sales tax separately from the federal system.

    Quebec Corporate Tax

    Quebec's general corporate rate is 11.5%, with a reduced rate for eligible small businesses and a DPE deduction.

    Revenu Québec

    Quebec businesses file separately with Revenu Québec for QST and provincial income tax — a dual filing requirement unique to Quebec.

    QPIP Premiums

    The Quebec Parental Insurance Plan requires employer and employee contributions, replacing federal EI parental benefits in Quebec.

    Quebec R&D Credits

    Quebec offers generous R&D tax credits up to 30% for eligible innovation and research activities conducted in the province.

    Quebec Personal Tax

    Quebec has the highest personal tax rates in Canada, with brackets from 14% to 25.75%, offset by various provincial credits.
