GST Calculator Canada
5% federal, and whatever the province adds.
5% federal, and whatever the province adds. Federal GST is 5% everywhere in Canada.
Rates change with budgets and local ballot measures, and the rate that applies depends on the delivery address and product category. Treat these as planning figures, not as a filing.

Federal GST is 5%. Provinces either harmonise it into HST, charge a separate PST, or charge nothing extra, so the rate a customer pays depends entirely on the province.
How the GST Calculator Canada works
Federal GST is 5% everywhere in Canada. What the customer actually pays depends entirely on the province: harmonised provinces fold it into a single HST, PST provinces charge a separate provincial tax alongside, and Alberta charges nothing extra.

The underlying calculation
Canada layers federal GST at 5% with provincial taxes in three different arrangements. In HST provinces the two are combined into a single harmonised rate. In PST provinces they apply separately. In Alberta and the territories only the 5% GST applies.
Total = net × (1 + applicable combined rate), where the applicable rate is determined by the place of supply, for goods shipped to a customer, normally the destination province.
Worked through
A C$51.33 net price. Alberta: 5% GST, C$53.90. Ontario: 13% HST, C$58.00. Nova Scotia: 15% HST, C$59.03. British Columbia: 5% GST plus 7% PST applied to the same base, C$57.49. Quebec: 5% GST plus 9.975% QST, C$59.02.
Five provinces, five totals, one net price. A business selling nationally applies all of them.
The recoverability differs too: HST and QST are fully creditable, while BC's PST is a cost. Two provinces with near-identical headline rates can have materially different real costs for a business operating in them.
Where it goes wrong
Zero-rated is not exempt. Basic groceries, prescription drugs and exports are zero-rated with full input credit; financial services and residential rent are exempt with none.
Place-of-supply rules for services and digital products are more complicated than for goods, turning on the customer's address and sometimes on where the service is performed. Applying the goods rule to a service supply is a common error.
Making it useful
Register federally once past the C$30,000 small supplier threshold, and then separately for QST and any applicable PST. There is no single Canadian registration that covers everything.
Then apply the destination province's rate rather than your own. A business shipping nationally from Ontario charges 15% to Nova Scotia, not 13%.
The small supplier threshold and its trap
The C$30,000 threshold is measured over four consecutive calendar quarters, and it can also be triggered by a single quarter exceeding it. Crossing in one quarter makes the business a registrant immediately for supplies from that point.
The trap is that the threshold counts worldwide taxable supplies rather than Canadian ones, which catches businesses that assume only domestic revenue counts.
Voluntary registration below the threshold is worth running the numbers on. A product business buying stock with GST or HST on it recovers real money; a service business selling to consumers with few taxable inputs mostly acquires a price disadvantage and a filing calendar. The calculation is annual recoverable input tax against output tax that cannot be passed on in price, and it usually resolves clearly in one direction.
Input tax credit claims require specific information on the supporting document, and the requirements scale with the amount, more detail is needed above certain thresholds, including the supplier's registration number.
A receipt that suffices for a small purchase does not necessarily support a claim on a large one, which is the kind of distinction that surfaces only in an audit of the larger items.
Recording the supplier's GST or HST number at onboarding rather than hunting for it per invoice removes the problem entirely.

Frequently asked questions
What is the GST rate in Canada?
5% federally. Combined rates range from 5% in Alberta and the territories to 15% in the Atlantic HST provinces, depending on what the province adds.
Which rate do I charge?
The rate for the customer's province under the place of supply rules, for shipped goods, the delivery address. An Alberta business shipping to Ontario charges 13% HST, not 5%.
When must I register?
Above C$30,000 of taxable revenue over four consecutive quarters. Below that you are a small supplier and registration is optional, though registering lets you claim input tax credits, which often makes it worthwhile.
What are input tax credits?
Recovery of GST and HST paid on business purchases, deducted from what you collected. PST in most provinces is not recoverable this way, which makes it a genuine cost rather than a pass-through.
