GST/HST Small Supplier Threshold Checker
Check whether you are a small supplier and whether you need to register for GST/HST based on your taxable revenue over four quarters.
GST/HST small supplier threshold checker
Enter your revenue from taxable supplies (not including the GST/HST you collect) for the last four consecutive calendar quarters. The checker applies the CRA’s $30,000 small supplier test and tells you whether you must register.
How this is estimated: the checker adds the four quarterly amounts you enter and compares the four-quarter total and each single quarter with the $30,000 small supplier threshold. It is a guide only — confirm your status on canada.ca.
