Calculator Formula

Here is how the total is calculated before sales tax:
Amount with sales tax / (1+(GST and QST rate combined/100)) or 1.14975 = Amount without sales tax
Amount without sales tax * GST rate = GST amount
Amount without sales tax * QST rate = QST amount

What is GST and QST in CANADA?

GST means goods and services tax and it is a federal tax that is levied by the federal government in every province in Canada.

PST means provincial sales tax and every province expect Alberta has to come under this.

HST (GST+PST) is the combination of GST and PST (the total tax that you have to think about paying). This applied to the provinces of New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario and Prince Edward Island. These provinces don’t apply GST and PST separately; they levy one combined tax called HST.

QST and RST:

In Quebec the provincial sales tax is known as Quebec sales tax. In Quebec, merchants have to pay GST and QST for all the sales made.

In Manitoba, provincial sales tax is known as RST which stands for Retail Sales Tax. Here in Manitoba merchants have to pay GST and RST for all the sales made.

Now it depends in which province or territory you stay and operate your organizations and under which tax collection system (GST, PST, HST) you come.

How place of supply affects GST/HST rates

What rate of tax any business has to pay depends upon where you make your sales, lease, or other supply. Product that is rated with zero tax has 0% GST/HST rate throughout all of Canada.
