Canada invoice compliance
What should your invoice include?
Why invoice details matter
When you are GST/HST registered and charge tax, your invoice is often your customer's proof for claiming ITCs. Missing fields can delay payment or trigger accounting pushback.
Amount thresholds (2021 rules)
Since April 20, 2021, CRA uses $100 and $500 thresholds for GST/HST input tax credit documentation — replacing the old $30 and $150 limits. Under $100 needs fewer fields; $100–$499.99 adds tax details when registered; $500+ adds buyer name, description, and payment terms. Tax status per supply is required only when a single invoice includes both taxable and exempt supplies.
