How it is computed
GST = price × 5% and QST = price × 9.975%, each rounded to the cent; the QST is calculated on the price before GST. Total = price + GST + QST.
FAQ
Is the QST calculated on the price including GST?+
No. Since January 1, 2013 the QST applies to the price before GST, so the two taxes together are 14.975% of the price.
How do I find the price before taxes from a total?+
Divide the total by 1.14975. The reverse sales tax calculator does it and splits the GST and QST.
