Tax rate GST and QST for 2017

GST rates are the same since 2008 at 5%.

The QST rate is the same since 2013 at 9.975%. However, the “final rate” remains the same since 2012 as the method of calculating QST has changed on January 1st 2013.

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

GST is a tax in Canada on sales of products and services. The GST rate in Québec starting in 2017 is 5%. All sales tax calculations are comparable, where you increase the cost of the products by 1 or more the tax rate to locate the total bill. Subsequently, so as to reverse calculate the GST and QST; you have to know how much your total bill was and the tax rate. This authorizes you to evaluate how much the bill was without GST and QST. The difference between the bill with and without the GST is the GST.

Margin of error for sales tax

An error margin of $ 0.01 may appear in the sales tax calculator. Any person selling anything should locate the net and gross cost dependent on their desired margin and the sales tax rate sooner or later. Don’t hesitate to analyze anything you like – you might be interested in the amount you of your payment is going to the distributor (if you give the gross margin and your cost) or, in case you’re the distributor, what margins you’re getting, given certain cost and your cost. We additionally have a variation that figures out margin and GST and QST if you happen to live or work in a country where value added tax is being used.
