Questions
How do I remove GST or HST from a total?
Divide by 1 plus the combined rate, do not subtract the percentage. A $113 total in Ontario at 13% HST is $113 ÷ 1.13 = $100.00 before tax. Subtracting 13% would give $98.31, which is wrong, because the tax was charged on the smaller pre-tax figure rather than on the total. Switch this calculator to 'Remove tax' and it does the division and splits out the components.
What is the difference between GST, HST, PST and QST?
GST is the 5% federal tax charged everywhere. HST is a single harmonised tax that folds the federal and provincial portions together, used in Ontario and the four Atlantic provinces. PST is a separate provincial tax charged alongside GST in British Columbia and Saskatchewan; Manitoba calls its version RST and Quebec calls its version QST. Alberta and the three territories charge GST only.
Does QST get charged on top of the GST in Quebec?
Not since 1 January 2013. QST used to be calculated on the GST-inclusive amount, which compounded the two taxes. Both now apply to the pre-tax price, so Quebec's combined rate is exactly 14.975%. Calculators that were never updated still produce a slightly higher figure — if yours gives more than 14.975%, it is using the old rule.
Which province's rate applies when I ship out of province?
Generally the province where the customer takes delivery — the place of supply — not where the seller is based. An Alberta business shipping to Ontario charges Ontario's 13% HST, not Alberta's 5%. For digital products and services the rules turn on the customer's usual address, and since 2021 they apply to non-resident sellers too.
When does a business have to register for GST/HST?
Once taxable revenue passes $30,000 over four consecutive calendar quarters, registration is mandatory. Below that it is voluntary and often still worthwhile, because registering lets you claim input tax credits on the tax you pay suppliers. PST, RST and QST have separate registrations with their own thresholds and rules.
Are these rates current?
They are current for 2026. The most recent change was Nova Scotia's HST dropping from 15% to 14% on 1 April 2025, so any calculator still showing 15% for Nova Scotia is out of date. Rates change rarely, but for anything you are actually filing, confirm against the Canada Revenue Agency's published figures.
About gst/hst calculator
Three different systems, one country
Canada does not have a single sales tax. Which one you pay depends entirely on where the sale takes place, and the three regimes behave differently enough that a calculator built for one gets the others wrong.
- HST — one harmonised tax, collected federally and shared with the province. Ontario, New Brunswick, Newfoundland and Labrador, Nova Scotia and Prince Edward Island.
- GST + PST — two separate taxes with separate rules and separate registrations. British Columbia, Manitoba (where it is called RST), Saskatchewan, and Quebec (where it is QST).
- GST only — Alberta and the three territories have no provincial sales tax at all.

Backing tax out of a total
This is where most people get it wrong. If a receipt says $113 including 13% HST, the pre-tax price is not $113 minus 13%. That would give $98.31, which is too low, because the 13% was charged on the smaller pre-tax figure rather than on the total. Divide instead: $113 ÷ 1.13 = $100.00.
Switch the calculator to “Remove tax” and it does that division, then splits the result back into its federal and provincial components — which is what you need for an expense claim or an input tax credit.
Quebec, and the change most calculators missed
Until 1 January 2013, QST was calculated on the GST-inclusive amount, so the two taxes compounded and the true combined rate was slightly above the sum of the parts. That stopped: both now apply to the pre-tax price, making the combined rate exactly 14.975%. Plenty of calculators were never updated. If one gives you a Quebec figure higher than 14.975%, it is still applying the pre-2013 rule.
Which province’s rate applies?
Generally the province where the customer takes delivery — the place of supply — not where the seller is based. An Alberta business shipping goods to Ontario charges Ontario’s 13% HST, not Alberta’s 5%. For digital products and services the rules turn on the customer’s usual address, and since 2021 they catch non-resident sellers too.
Some goods are zero-rated or exempt everywhere: basic groceries, prescription drugs, most medical devices, and residential rent among them. Several provinces add their own point-of-sale rebates on top — Ontario, for instance, rebates the provincial portion on children’s clothing, books and prepared food under $4, effectively dropping those to 5%.
Registering as a business
Once your taxable revenue passes $30,000 over four consecutive calendar quarters, GST/HST registration is mandatory. Below that it is voluntary — and often still worth doing, because registering lets you claim input tax credits on the tax you pay to suppliers. PST, RST and QST have their own separate registrations and thresholds.
Rates on this page are current for 2026. The last change was Nova Scotia’s HST falling from 15% to 14% on 1 April 2025. For anything you are filing, confirm against the Canada Revenue Agency’s published rates — this is an estimate, not tax advice.
