GST and QST on receipts
How Quebec sales are taxed, and the summary you use to file.
For a Quebec store, a receipt shows the GST and the QST, each with its registration number. The QST is calculated on the price before the GST.
Each rate is stored with its date, so a sale is taxed at the rate that applied the day it was made.
In the office, the tax summary for a period adds up the taxes collected, to help you prepare your return. Filing itself is done with the tax authorities.
