GST, HST, PST, RST, and QST in Canada
The federal GST (5%) applies everywhere, but what happens after that depends on the province:
- Alberta, NWT, Nunavut, and Yukon charge GST only
- BC, Manitoba, and Saskatchewan add PST/RST on top of the pre-tax price
- Ontario and the Atlantic provinces use a single harmonized HST instead of separate lines
- Quebec applies GST + QST, and QST gets calculated on the GST-inclusive amount rather than the base price
