Canada FAQs
What is the GST rate in Canada?
The federal GST rate is 5%, applied nationwide. In HST provinces (Ontario 13%, NB/NS/NL/PEI 15%), the provincial portion is combined with GST into a single harmonized rate. Alberta, NWT, Nunavut, and Yukon have only the 5% federal GST.
What is the difference between GST and HST?
GST is the 5% federal goods and services tax. HST (Harmonized Sales Tax) combines the 5% federal GST with a provincial component into one rate. Ontario HST is 13% (5% + 8%). Atlantic HST is 15% (5% + 10%). They work identically at checkout.
What is exempt from GST in Canada?
Basic groceries (but not snacks, candy, or prepared food), prescription medicines, medical devices, most health and dental services, child care, educational services, and residential rent are GST/HST-exempt.
How do I calculate GST from a Canadian price?
To add 5% GST: multiply by 1.05. CAD 100 becomes CAD 105. To remove GST from an inclusive price: divide by 1.05. CAD 105 / 1.05 = CAD 100. For HST provinces, use 1.13 (Ontario) or 1.15 (Atlantic).
Can businesses claim GST back?
Yes. GST-registered businesses claim input tax credits (ITCs) for GST/HST paid on business purchases. This is done through regular GST/HST returns filed with CRA, typically quarterly or annually depending on revenue.
When must I register for GST in Canada?
GST registration is mandatory when worldwide taxable revenue exceeds CAD 30,000 in four consecutive calendar quarters. Below this threshold, registration is voluntary but allows you to claim input tax credits on business expenses.
