HST calculator for every Canadian province
Canadian sales tax depends on where the supply is made: 13% HST in Ontario, 14% in Nova Scotia, 15% in New Brunswick, Newfoundland and Labrador and Prince Edward Island, and 5% GST elsewhere, with PST or QST added in some provinces. Pick the province and this calculator adds the tax or takes it out, one line per tax.

Copy the split into a quote or an invoice, or try the Quebec example to see GST and QST side by side.
The 13 provinces and territories
Five provinces have a harmonized sales tax that replaces the GST and the provincial tax with one rate: Ontario at 13%, Nova Scotia at 14% since 1 April 2025, and New Brunswick, Newfoundland and Labrador and Prince Edward Island at 15%. Alberta, the Northwest Territories, Nunavut and Yukon charge only the 5% GST. British Columbia adds a 7% PST, Saskatchewan a 6% PST and Manitoba a 7% retail sales tax, each collected separately from the GST. Quebec adds the 9.975% QST. The CRA's rate table lists all 13, and the selector follows it.
Why QST and PST are not compounded
In every province the provincial tax is worked out on the price before tax, not on the price plus GST. A $100 sale in Quebec carries $5 GST and $9.975 QST, for $114.975 in total; the two rates simply add to 14.975%. The same is true of PST in British Columbia, Saskatchewan and Manitoba. To take tax out of an inclusive price, the calculator divides by 1 plus the combined rate, then works each tax from the price it finds, and puts any rounding cent on the last line so the parts add up to the total.
Place of supply decides the rate
The rate is set by where the supply is made, not where the seller is. The CRA's own example is a Vancouver store delivering a mattress to Toronto: the sale is made in Ontario, so it carries 13% HST. A customer who collects goods in Winnipeg pays GST and Manitoba's tax instead. Services have their own rules, generally based on the customer's address. If a business ships across the country, the province in its invoice address is often the wrong one to use.
Nova Scotia's 2025 change
Nova Scotia cut the provincial part of its HST from 10% to 9% on 1 April 2025, taking the combined rate from 15% to 14%. Invoices for supplies made before that date keep 15%, and the CRA published transitional rules for work that spans it. The calculator uses 14% for Nova Scotia; a past invoice may need the old rate, which the CRA's history table shows.
Showing the tax on a quote
A quote to a business usually shows the price before tax and each tax line, because the buyer claims input tax credits on the GST or HST. A provincial PST is generally a cost to the buyer and is shown separately for that reason. The proposals module sets one tax rate per line and labels the tax line Tax for Canadian dollars, so for a single tax province set that rate on each line; for a two tax province, combine them or list them as the client expects.
Limits
- Rates checked on 21 October 2026 against the CRA's GST/HST rate table, which lists the PST and QST rates beside them. This is arithmetic, not tax advice.
- Every tax is worked out on the price before tax, so no tax is charged on another tax.
- No point of sale rebates, no item level PST exemptions and no registration threshold logic.
- The place of supply decides the rate; the tool applies the province you choose.
What it does not do
- It does not file a GST/HST return or a provincial return.
- It does not decide the place of supply for you.
- It does not store the amount.
Questions people ask
What HST rate applies to a sale delivered in Ontario?
13%, of which 5% is the federal part and 8% the provincial part. It has been 13% since HST replaced Ontario's separate retail sales tax in 2010. A $200 sale delivered in Ontario carries $26 of HST, for a total of $226.
How do I remove HST from a price?
Divide the tax inclusive price by 1 plus the rate. In Ontario that is 1.13, so $565 includes $65 of HST and $500 before tax. In New Brunswick divide by 1.15 and in Nova Scotia by 1.14. To find only the tax, subtract the result from the inclusive price.
Is QST charged on top of GST?
No. QST is calculated on the selling price before GST, so the two taxes are charged side by side on the same base. On $1,000 the GST is $50 and the QST is $99.75, for a total of $1,149.75. The CRA rate table lists the QST in its own column for that reason.
Which provinces only charge GST?
Alberta and the three territories, the Northwest Territories, Nunavut and Yukon, have no provincial sales tax, so only the 5% GST applies there. British Columbia, Saskatchewan and Manitoba charge GST plus their own provincial tax, and Quebec charges GST plus QST.
Do I charge HST if I am a small supplier?
A small supplier, generally one with taxable supplies of $30,000 or less over four consecutive calendar quarters, does not have to register for GST/HST and does not charge it unless registered voluntarily. Provincial taxes in British Columbia, Saskatchewan, Manitoba and Quebec have their own registration rules.
Why is the last tax line a cent different?
When tax is taken out of an inclusive price, the price before tax is rounded to the cent first and each tax is worked from it. Any cent left over is placed on the last tax line, so the parts always add up to the amount typed rather than drifting a cent away from it.
