# compliance.gstHst.deadlines

Read only the company's GST/HST filing and payment deadlines, reporting periods, confirmed reporting schedule, official CRA sources and exact missing setup. Uses current saved settings, keeps tax numbers private and does not open the private tax-details form. Returns the next open deadline and a bounded list of overdue and upcoming dates; marked done does not prove CRA payment. Show this focused view when asked when HST is due or must be paid. Saving money in a reserve account is separate from paying CRA.
