To find the pre-tax price, you divide the tax-included total by one plus the applicable combined tax rate. A reverse sales-tax calculator handles the correct GST, HST, PST or QST structure for the selected province.
Divide the tax-included amount by 1 plus the HST rate expressed as a decimal. The difference between the total and the calculated pre-tax price is the HST included in the original amount.
A reverse Quebec sales-tax calculation uses the combined effect of the applicable GST and QST rates to determine the pre-tax price. The calculator then separates the estimated GST and QST contained in the total.
No. If tax was added to a pre-tax price, subtracting 13% of the tax-included total does not return the original amount. You need to divide the total by 1.13 when the applicable HST rate is 13%.
The included tax equals the total price minus the calculated pre-tax price. The exact amount depends on the province and tax rate applicable to the transaction.
