Canada's sales tax system has three components: GST (federal 5%, applies everywhere), HST (harmonized, used in Ontario and Atlantic provinces — it bundles federal GST with the provincial share into one tax), and PST/RST/QST (provincial taxes charged separately in BC, Manitoba, Saskatchewan, and Quebec). As of April 1, 2025, Nova Scotia reduced its HST from 15% to 14%. Alberta, Yukon, NWT, and Nunavut have no provincial sales tax — only 5% GST.

HST provinces (Ontario, Atlantic): One clean line on invoices. A contractor in Ontario charging $10,000 adds 13% HST ($1,300), for a total of $11,300. The CRA receives the full HST and shares the provincial 8% portion with Ontario.
GST + PST provinces (BC, MB, SK): Two separate taxes, filed separately. A $10,000 BC invoice shows GST $500 (to CRA) and PST $700 (to BC provincial government) — total $11,200. These cannot be combined on one line.
Quebec (GST + QST): Quebec administers both taxes through Revenu Québec. QST at 9.975% is applied to the same pre-tax price as GST. Total on $10,000: GST $500 + QST $997.50 = $11,497.50.
GST-only (Alberta, Territories): Canada's lowest-taxed regions. $10,000 + 5% GST = $10,500. No provincial layer.
Zero-rated (0% GST/HST): Tax is not collected but businesses can still claim input tax credits (ITCs). Examples: basic groceries, prescription drugs, exported goods and services, agriculture and fishing supplies, medical devices.
Exempt supplies: Not taxable and no ITCs can be claimed on related expenses. Examples: residential rent, most healthcare and dental services, childcare, public transit, financial services, educational services from public institutions, music lessons by qualifying teachers.
Key rule: You cannot register for GST/HST if you provide only exempt supplies. If you mix taxable and exempt supplies, you must apportion your ITCs accordingly.
