GST/HST Threshold Predictor for Canada

See how close you are to the $30,000 small supplier threshold and when CRA requires you to register for GST/HST.

The $30,000 GST/HST threshold is a federal rule that applies the same way in every province and territory. Once your taxable revenue passes $30,000 in a single calendar quarter, or across any four consecutive quarters, you stop being a small supplier and must register within 29 days. The rate you charge after that depends on your province. Pick yours below for the local rate and a province-specific breakdown.
