🇨🇦 Canada GST/HST Calculator 2026 — All Provinces
Calculate GST, HST, PST, or QST for any Canadian province or territory. Add tax to a price or remove it from a gross total — results update instantly.
Canada's sales tax system is uniquely complex because it layers a federal 5% GST on top of province-specific taxes that go by different names — HST in Ontario and the Atlantic provinces, PST in BC and Saskatchewan, RST in Manitoba, and QST in Quebec. For anyone selling across provincial borders, especially e-commerce businesses, this creates a patchwork of rates that ranges from 5% in Alberta to 15% in New Brunswick.
The most common mistake we see is businesses applying their home province's rate to all customers. Place-of-supply rules mean the rate depends on where the customer receives the goods or service, not where the seller is located. A Toronto-based SaaS company selling to a Vancouver client should charge 12% (BC), not 13% (Ontario).
This calculator lets you select any province and instantly see the combined rate with the GST/PST breakdown. For Quebec transactions, remember that QST is administered by Revenu Québec separately from CRA — you may need to file with both agencies.
Quick answer
Canada combined rates range from 5% (Alberta) to 15% (Atlantic HST)
Federal GST is 5% everywhere. Provinces add HST, PST, RST, or QST. Select your province below, then add tax to a net amount or remove tax from a gross total.

How to calculate GST/HST in Canada
Select your province, enter the amount, and choose add or remove mode.
- Pick the province or territory for place of supply.
- Enter net (before tax) or gross (tax-inclusive) amount.
- Use Add Tax for quotes; Remove Tax to back out tax from a receipt.
Tax = net × (combined rate ÷ 100)
Gross = net + tax
Net = gross ÷ (1 + rate ÷ 100)
Ontario HST 13%: $100 net → $13 tax → $113 total.
How sales tax works in Canada
Canada does not have a single national sales tax rate. The federal Goods and Services Tax (GST) is 5% across the country. Provinces either participate in the Harmonized Sales Tax (HST) — which merges federal and provincial components into one line — or charge a separate Provincial Sales Tax (PST), Retail Sales Tax (RST), or Quebec Sales Tax (QST) alongside GST. The rate on your invoice depends on place of supply, customer location, and product type.
Businesses registered for GST/HST charge tax on taxable supplies, issue invoices showing GST or HST registration numbers, and file returns with the Canada Revenue Agency (CRA). Quebec administers QST separately through Revenu Québec for most provincial obligations. Small suppliers below the $30,000 registration threshold may not need to register but lose input tax credit rights until they do.
GST, HST, PST, and QST by province
Alberta, Yukon, Nunavut, and Northwest Territories have no provincial sales tax — only 5% GST applies on taxable goods and services. Ontario uses 13% HST; the Atlantic provinces (New Brunswick, Newfoundland and Labrador, Nova Scotia, Prince Edward Island) use 15% HST. British Columbia charges 5% GST plus 7% PST (12% combined on many goods). Manitoba uses 5% GST and 7% RST; Saskatchewan uses 5% GST and 6% PST.
Quebec applies 5% GST and 9.975% QST, often quoted as 14.975% combined on consumer prices. Place-of-supply rules determine which rate applies when you ship from one province to another — critical for e-commerce and SaaS. This calculator models a single combined percentage you select; verify inter-provincial rules on CRA and provincial sites before filing.
Adding and removing GST/HST from amounts
Forward calculation: Tax = Amount × (Rate ÷ 100); Total = Amount + Tax. On a $100 net Ontario HST sale at 13%, tax is $13 and the customer pays $113. Reverse calculation: Net = Gross ÷ (1 + Rate ÷ 100). A $113 receipt in Ontario implies $100 before HST and $13 tax. The same math applies whether the label says GST, HST, or combined GST+PST — use the total effective rate.
Do not subtract the percentage from a tax-included price. At 15% HST, dividing by 1.15 is correct; subtracting 15% from the gross is not. For QST scenarios where GST and QST are calculated on different bases, use province-specific guidance — this tool uses one combined rate for estimates.
GST/HST registration and input tax credits
Most businesses with over $30,000 in taxable supplies in a single calendar quarter or in four consecutive quarters must register for GST/HST. Registration lets you charge tax on sales and claim input tax credits (ITCs) on GST/HST paid on business expenses. Exempt supplies (certain health, financial, and residential rent services) generally do not allow ITCs on related inputs.
File returns on your assigned reporting period — annual, quarterly, or monthly based on revenue. Keep invoices that show supplier GST/HST numbers, your business number, and tax breakdowns. Quick method accounting uses simplified remittance for eligible small businesses but changes how you calculate net tax. Consult CRA publications or a tax professional before electing special methods.
Common Canadian tax scenarios
Retail in Toronto (Ontario): $250 jacket + 13% HST = $32.50 tax, $282.50 total. E-commerce from BC to BC customer: often 12% (5% GST + 7% PST) on taxable goods. Shipping from Alberta warehouse to Ontario buyer: Ontario 13% HST usually applies on the taxable supply to the Ontario address. Zero-rated exports: GST/HST charged at 0% with proper documentation.
Software and digital services have specific place-of-supply rules that differ from physical goods. Indigenous exemptions and point-of-sale rebates exist in some provinces for status card holders. This calculator helps with arithmetic; classification and place of supply determine whether tax applies at all.
Using this Canada GST/HST calculator effectively
Select your province preset or enter a custom combined rate for unusual cases. Use add mode when you have a pre-tax quote; use remove mode when reconciling credit card statements or expense reports. Compare Ontario 13% versus Alberta 5% when pricing national e-commerce — the difference materially affects conversion and margin.
Pair this tool with our invoice calculator for multi-line bills and with provincial official rate tables before filing a GST34 return. Rates on this page are aligned to 2026 CRA references; budget changes and provincial announcements can alter percentages — always confirm before issuing formal tax invoices.
Common mistakes to avoid
Using Ontario HST for a BC customer
Place-of-supply rules determine which provincial rate applies on invoices and e-commerce.
Forgetting QST is filed in Quebec
Quebec QST is administered by Revenu Québec, not CRA, even though GST still applies.
Taxing exempt groceries at full HST
Basic groceries are often zero-rated for GST/HST even when other items are taxable.
Removing tax by subtracting the percentage
Divide the gross total by 1 + (rate ÷ 100). Example: $113 ÷ 1.13 = $100 net in Ontario.
