Put the key dates in your own calendar
Download the shared Ontario and CRA dates — T4 slips, employer health tax, instalment dates, self-employed filing deadlines — as a calendar file and import it into Google Calendar, Outlook, or Apple Calendar. Your own filing dates depend on your fiscal year-end and HST frequency, so confirm those with the official source.
