Canada's tax system combines federal GST (5%) with provincial sales taxes — either as a harmonized HST, or separate PST/QST alongside GST. Rates vary by province from 5% (Alberta) to 15% (Atlantic provinces). Businesses must understand registration, ITC claims, and filing obligations.
Canada has three types of sales tax arrangements: HST provinces (federal and provincial tax combined into one — Ontario 13%, New Brunswick/Nova Scotia/Newfoundland/PEI 15%), GST-only provinces (Alberta — 5% GST, no provincial sales tax), and GST + PST provinces (BC: 5% GST + 7% PST = 12%, Manitoba: 5% + 7% = 12%, Saskatchewan: 5% + 6% = 11%). Quebec has its own QST (9.975%) collected alongside 5% GST.
Calculation is straightforward: Tax = Price × Tax Rate. For GST+PST: the taxes are calculated on the pre-tax price (not on each other) — GST and PST are independent. Exception: Quebec — QST is calculated on the GST-inclusive price (tax-on-tax), making the effective rate slightly higher.
Businesses registered for GST/HST collect it from customers and remit to CRA (minus Input Tax Credits for GST/HST paid on business purchases). Small suppliers (under $30,000 annual revenue) are exempt from registration but cannot claim ITCs. Voluntary registration is available and often advantageous even below the threshold.
| Province/Territory | GST | PST/QST | HST | Total Rate |
|---|---|---|---|---|
| Ontario | — | — | 13% | 13% |
| British Columbia | 5% | 7% (PST) | — | 12% |
| Alberta | 5% | None | — | 5% |
| Quebec | 5% | 9.975% (QST*) | — | 14.975%* |
| Manitoba | 5% | 7% (RST) | — | 12% |
| Saskatchewan | 5% | 6% (PST) | — | 11% |
| Nova Scotia | — | — | 15% | 15% |
| New Brunswick | — | — | 15% | 15% |
| Newfoundland & Labrador | — | — | 15% | 15% |
| Prince Edward Island | — | — | 15% | 15% |
| Yukon / NWT / Nunavut | 5% | None | — | 5% |
*Quebec QST is calculated on the GST-inclusive price (tax-on-tax), making the effective combined rate approximately 14.975%.
Registered GST/HST businesses can claim Input Tax Credits (ITCs) — refunds of GST/HST paid on business purchases and expenses. This prevents cascading tax (tax on tax). Example: Restaurant pays 13% HST on $10,000 of supplies = $1,300 ITC claimed. Collects $13,000 HST from customers. Remits $13,000 − $1,300 = $11,700 net to CRA. ITCs make GST/HST effectively a consumer tax, not a business cost.
ITCs available on: business inputs (supplies, equipment), commercial real property, employees' reasonable travel expenses (if GST/HST paid). NOT available on: personal use portion of expenses, meals and entertainment (50% ITC only), passenger vehicles over $37,000 (limited ITC), exempt supplies (residential rent). Must have supporting documentation (supplier name, GST/HST number, date, description, GST/HST amount).
GST and HST are the same tax collected the same way
In HST provinces (Ontario, Atlantic), federal and provincial portions are combined in one collection — businesses file one return with CRA for both. In GST+PST provinces (BC, Saskatchewan, Manitoba), they are separate taxes collected separately. BC PST is filed with BC government; GST with CRA. Quebec's QST is collected by Revenue Quebec, not CRA (separate registration, separate return, separate payment).
If my revenue is under $30,000, I never need to deal with GST/HST
You don't have to register, but you might want to. Small suppliers can voluntarily register, allowing them to claim ITCs on business purchases. For product-based businesses with significant input costs, ITCs can exceed GST collected — resulting in net refunds from CRA. Also, once you exceed $30,000 in any single calendar quarter or over four consecutive quarters, you must register within 29 days. Taxi and ride-share drivers must register regardless of revenue.
Basic groceries are always GST-free in Canada
Zero-rated supplies (0% GST/HST) include most unprocessed foods: fresh fruits and vegetables, meat, poultry, fish, dairy, eggs, bread, cereal. But many prepared foods are taxable: chips, soft drinks, candy, fast food, restaurant meals, catering. The line is complex — a grocery store's rotisserie chicken is zero-rated if sold cold but taxable if sold hot. Plain biscuits are zero-rated; chocolate-dipped biscuits are taxable. Always check CRA guidance for specific items.
The PST in BC works the same as HST in Ontario
They are fundamentally different systems. BC PST: provincial tax only (7%), separate registration with BC government, separate annual return, does not allow ITC claims, has its own exemption list (manufacturing, software, certain services are PST-exempt). Ontario HST (13%): single combined tax, one CRA registration, one return, full ITC system. BC businesses must manage two separate tax systems (GST and PST), two registrations, two filings, two remittances.
