GST vs HST vs PST vs QST explained
The Goods and Services Tax is a federal 5% tax applied across all of Canada. It has been 5% since January 1, 2008 when it was reduced from 6% (and 7% before that). Administered by CRA for all provinces except Quebec, where CRA still collects it but Revenu Québec handles QST separately.
HST combines federal GST and provincial tax into a single rate. Ontario (13%), Nova Scotia (14%), New Brunswick, Newfoundland, and PEI (all 15%). Businesses file one return with CRA instead of separate federal and provincial returns. Simplifies compliance significantly.
BC (7%), Manitoba (7%), and Saskatchewan (6%) charge PST separately from GST. Key difference from HST: PST is not recoverable through Input Tax Credits — businesses cannot claim it back, making it a hard cost. Filed with the provincial government, not CRA.
Quebec's sales tax is similar to HST in structure but filed separately with Revenu Québec. QST is calculated on the pre-GST price (not on top of GST). Combined GST + QST = 14.975%. Businesses in Quebec must register with both CRA (GST) and Revenu Québec (QST).
To extract tax from a tax-inclusive total: divide by (1 + tax rate). Ontario example: $113 ÷ 1.13 = $100 pre-tax. Quebec is more complex because QST and GST are on the same base: divide by 1.14975. For BC or Manitoba: pre-tax = total ÷ 1.12. This calculator handles all formulas automatically.
Some goods and services are zero-rated (0% GST/HST) across all provinces: basic groceries (bread, milk, produce, meat), most prescription drugs, medical devices, and exports. These are different from exempt supplies — zero-rated businesses can still claim Input Tax Credits on their expenses.
GST/HST FAQs
When do I have to register for GST/HST?
You must register for GST/HST when your business revenue exceeds $30,000 over four consecutive calendar quarters (the "small supplier threshold"). Once registered, you collect and remit GST/HST on all taxable sales. You can register voluntarily before hitting this threshold to claim Input Tax Credits on your business expenses.
Why is Nova Scotia now 14% instead of 15%?
The Government of Nova Scotia reduced the provincial portion of HST from 10% to 9% effective April 1, 2025, bringing the combined HST rate down from 15% to 14%. Transitional rules apply for supplies straddling the April 1 date — the rate that applies depends on when the supply is considered to have been made under the Excise Tax Act.
Does Alberta have a provincial sales tax?
No. Alberta is the only province in Canada with no provincial sales tax. Consumers and businesses in Alberta only pay the 5% federal GST. This makes Alberta's effective sales tax rate the lowest in Canada and is one of the financial advantages cited by businesses choosing to locate there.
What are Input Tax Credits (ITCs)?
Registered GST/HST businesses can recover the GST/HST paid on business expenses by claiming Input Tax Credits on their GST/HST return. This is a major advantage of HST provinces — a business pays 13% HST on a purchase but recovers all 13% through ITCs. In PST provinces (BC, SK, MB), only the 5% GST portion is recoverable — the PST is a permanent cost.
How is QST different from PST?
Both are provincial taxes, but QST functions more like a value-added tax (similar to HST) — registered businesses can claim Input Tax Refunds (ITRs) for QST paid on business purchases. PST in BC, Manitoba, and Saskatchewan is not recoverable by businesses. Both rates are calculated on the pre-GST price, not on the GST-inclusive amount.
How do I calculate HST backward from a total?
Divide the tax-inclusive total by (1 + HST rate). For Ontario: divide by 1.13. Nova Scotia: divide by 1.14. New Brunswick/NL/PEI: divide by 1.15. The result is the pre-tax amount; subtract from the total to get the HST amount. This "Extract tax from total" mode is built into this calculator — just switch the mode button above and enter your total.
