GST/HST calculator
Add sales tax to a price, or pull the tax out of a receipt total. Every province and territory, with the GST, HST, PST and QST split out.
Accountly tracks the tax you collect and your input tax credits all year.
This is a rough estimate and may be inaccurate — it is not tax advice. Rates change (Nova Scotia's HST dropped to 14% on April 1, 2025), some goods and services are zero-rated or exempt, and place-of-supply rules decide which province's rate applies. Confirm with the Canada Revenue Agency and a qualified accountant.
GST/HST in plain English
If you're self-employed in Canada, sales tax shows up on both sides of your business — what you charge customers and what you can claim back.
When you must register
Once your revenue passes $30,000 over four consecutive quarters, you're no longer a small supplier — you must register, charge GST/HST, and remit it to the CRA.
Input tax credits
Registered businesses claim back the GST/HST paid on business purchases as input tax credits (ITCs) — keeping receipts is literally money.
Rates differ by province
HST provinces bundle everything into one rate (Ontario 13%, Nova Scotia 14%, the rest 15%). Others charge 5% GST plus a separate PST/QST that isn't part of the GST/HST system.
GST/HST questions
What are the GST/HST rates by province in 2026?
HST provinces: Ontario 13%, Nova Scotia 14% (reduced from 15% on April 1, 2025), and New Brunswick, Newfoundland and Labrador, and PEI 15%. Everywhere else charges 5% federal GST, and BC (7% PST), Saskatchewan (6% PST), Manitoba (7% RST), and Quebec (9.975% QST) add a separate provincial sales tax on top. Alberta and the territories charge GST only.
When do I have to register for GST/HST?
When your worldwide taxable revenue exceeds $30,000 over four consecutive calendar quarters (the small-supplier threshold). You can also register voluntarily below that — useful if you want to claim input tax credits on your expenses.
Which province’s rate do I charge?
Generally the rate of the province where you make the supply — for goods, usually where they’re delivered; for most services, the customer’s location. These "place of supply" rules have exceptions, so check the CRA rules or ask an accountant for your situation.
How do I take the tax out of a receipt total?
Divide the total by 1 plus the rate. A $113.00 receipt in Ontario is $113 ÷ 1.13 = $100 before tax, so $13.00 is HST. The "price already includes tax" mode above does this for you — handy for receipts where the tax isn’t broken out.
Is PST the same as GST/HST?
No. PST (BC, Saskatchewan), RST (Manitoba), and QST (Quebec) are provincial taxes outside the federal GST/HST system — you generally can’t claim input tax credits for them. The calculator shows them so you see the full amount a customer pays.
Do I charge GST/HST on zero-rated or exempt sales?
No — zero-rated supplies (like basic groceries and exports) are taxed at 0%, and exempt supplies (like most health care and financial services) aren’t taxed at all. The difference matters for input tax credits: you can claim ITCs for zero-rated sales but not exempt ones.
This is a rough estimate — it may be inaccurate, and it is not tax advice. Rates change, our numbers can be wrong or out of date, and many goods, services, and situations follow special rules (zero-rated, exempt, place-of-supply). Don't charge, file, or remit based on this alone — confirm with the Canada Revenue Agency and a qualified accountant first.
