Methodology
The combined rate is the CRA rate in effect for 2026. Provincial sales tax is applied to the pre-tax price. Removing tax divides the tax-included total by one plus the combined rate, then recalculates the parts. Exempt and zero-rated supplies are out of scope. Place-of-supply rules can move a sale into a different province's rate.
