GST/HST Calculator
Add GST/HST to a price, or pull it back out of a tax-included total, using the current rate for your province. In British Columbia, Manitoba and Saskatchewan it also shows the provincial sales tax on top of the 5% GST.
Flat-rate estimate. Some goods and services are zero-rated or exempt, and PST/RST have their own exemptions — your actual invoice can differ.
Rates checked against the official CRA table (canada.ca) on July 17, 2026.

Do you have to charge GST/HST?
You generally have to register once your taxable sales pass $30,000 — measured either in a single calendar quarter, or over the last four consecutive quarters. Below that you're a "small supplier" and registering is optional. How soon you have to start charging depends on which way you cross it.
Pass $30,000 in a single quarter and you're generally over the line right away — you charge GST/HST starting with the sale that put you over. Reach it more gradually, across four quarters, and you generally stay a small supplier for about a month longer before you have to register and start charging. Either way the $30,000 counts your worldwide taxable sales and those of anyone you're associated with — not your profit — and if you register late the CRA can still hold you responsible for the tax you didn't collect.
FAQ
Switch the calculator to "Take GST/HST out of a total" and enter the tax-included amount. It divides by one plus your province's rate to find the pre-tax price, then shows the tax. For 13% HST, for example, a $113 total is $100 before tax and $13 HST.
It's 13% in Ontario; 15% in New Brunswick, Newfoundland & Labrador and PEI; 14% in Nova Scotia since April 1, 2025; and 5% GST in Alberta and the territories. BC, Manitoba and Saskatchewan charge 5% GST plus their own PST/RST.
No. GST and HST are federal (CRA). PST in BC and Saskatchewan, and RST in Manitoba, are provincial taxes with their own rules and exemptions, so this tool shows them as a separate line.
No — it applies the flat statutory rate. Some things (basic groceries, many financial and health services) are zero-rated or exempt, and PST/RST have their own exemptions, so your real invoice can differ. When it matters, check with us.
Usually the customer's. GST/HST follows "place of supply" rules, so a sale to an Ontario customer generally carries 13% HST even if you're based in Alberta. The rules have exceptions — ask us if you sell across provinces.
