How GST/HST works

Canada's federal GST is 5% everywhere. Five provinces fold it into a single HST (Ontario 13%; Nova Scotia 14%; New Brunswick, Newfoundland & Labrador and PEI 15%). Others add a separate PST/RST/QST alongside GST — British Columbia is 5% + 7% = 12% — while Alberta and the territories charge GST only at 5%.

To add tax, multiply the pre-tax price by one plus the combined rate; to extract tax from a tax-inclusive total, divide by one plus the rate. In PST provinces both taxes apply to the same pre-tax amount, not on top of each other. Registered businesses claim back the GST/HST they pay on purchases (input tax credits), so the tax ultimately falls on the final consumer.

FAQ

What's the difference between GST, HST and PST?
GST is the 5% federal tax. HST combines GST with the provincial portion into one rate. PST/RST/QST is a separate provincial tax charged alongside GST in BC, Saskatchewan, Manitoba and Quebec.
Why is Alberta cheaper?
Alberta has no provincial sales tax, so only the 5% federal GST applies — the lowest in Canada, like the territories.
When must a business register?
Once taxable revenue exceeds $30,000 over four consecutive calendar quarters (or in a single quarter).
What is exempt?
Basic groceries, prescription drugs, most health and dental, and residential rent are exempt or zero-rated.
