    Ottawa Tax Landscape

    Here's what you should know about taxes in Ottawa, Ontario.

    Ontario HST (13%)

    Ottawa businesses collect 13% HST (5% GST + 8% Ontario PST) on taxable goods and services.

    Ontario Corporate Tax

    Ontario's general corporate rate is 11.5%, with a 3.2% small business rate on the first $500,000 of active income.

    Government Contracting

    Ottawa's proximity to federal government creates unique GST/HST considerations for government contractors and suppliers.

    Cross-Border (QC/ON)

    Ottawa businesses near the Quebec border may deal with clients in both provinces, requiring knowledge of both HST and QST systems.

    Ontario EHT

    Employers with Ontario payroll exceeding $490,000 must pay Employer Health Tax at rates up to 1.95%.

    Bilingual Market

    Ottawa's bilingual nature means businesses often serve both Ontario and Quebec clients, each with different tax regimes.
