Important: The $30,000 small supplier threshold applies to worldwide taxable supplies — not just Ontario sales. The threshold is calculated on a rolling 4-consecutive-quarter basis, not just a calendar year. Taxi and rideshare drivers must register from the first dollar earned. Certain supplies (residential rent, most healthcare, legal aid) are HST-exempt and do not count toward the threshold.
