How PST works alongside GST
British Columbia, Saskatchewan and Manitoba charge their own provincial sales tax on top of the 5% federal GST. The two taxes are registered, collected and filed separately: GST with the CRA, PST or RST with the province.
This calculator works out each tax on the price before tax and shows them as separate lines, the way they usually appear on an invoice.
