Why are the supplies GST/HST-included?

The Quick Method applies the remittance rate to revenue including the GST/HST you charged.

How the estimate works

CRA guide RC4058 sets out the Quick Method as: tax-included revenue from eligible supplies times your remittance rate, minus a 1% credit on the first C$30,000 of eligible supplies in the fiscal year, minus input tax credits on capital purchases.

The quick-pick buttons carry the four rates CRA publishes for businesses in 5% GST provinces and in Ontario (checked September 2026). Rates for other provinces, and for supplies made in more than one province, differ; type yours from the guide.

This is guidance, not a return. Eligibility, elections and the rate that applies to you are for you and your accountant to confirm.
