Alberta and Quebec administer their own corporation income tax systems. Ontario corporate income tax is administered by Ontario for taxation years ending before 2009, and by Canada Revenue Agency (CRA) for taxation years ending after 2008. Corporations earning income in provinces which administer their own corporate taxes must file both provincial and federal corporate income tax returns. CRA administers the corporate income tax for all other provinces.
