Updated Checked by the Tax-Services.ca editorial team How we check
Sales tax compliance across provinces comes down to three jobs: charge the right rate for where the sale is made, register once you pass $30,000 in taxable sales, and keep records for six years. The hard part is the first one, because the same $2,500 sale carries $125.00 of tax in Alberta, $325.00 in Ontario and $374.38 in Quebec.
Which rate applies to a sale?
The CRA calls it the place of supply: the province or territory where a sale is treated as made. That place sets the GST/HST rate, and it isn’t always where your shop is. The CRA has separate rules for goods, services, real property and digital items, and we haven’t tried to boil them into one rule here. For each product type, read the place of supply guidance before you assume the buyer’s address or yours decides it.
What we can give you is the rate once you know the place. Use the table below for goods, priced at $1,000 before tax.
| Where the sale is made | Tax layout | Tax on $1,000 |
|---|---|---|
| Ontario | 13% HST | $130.00 |
| New Brunswick, Newfoundland and Labrador, PEI | 15% HST | $150.00 |
| Nova Scotia | 14% HST | $140.00 |
| Saskatchewan | 5% GST + 6% PST | $110.00 |
| British Columbia | 5% GST + 7% PST | $120.00 |
| Quebec | 5% GST + 9.975% QST | $149.75 |
| Alberta and the territories | 5% GST | $50.00 |
Who has to follow sales tax compliance rules, and when?
A small supplier has no duty to register. The CRA sets that line at $30,000 of taxable sales over four calendar quarters in a row, for most businesses. If one single quarter takes you past it, you start charging GST/HST on the sale that crossed the line.
When you cross it over several quarters, you stay a small supplier until the end of the month after the quarter that put you over. After that, you charge on your next sale. Either way you’ve got 29 days from your effective date to register. Miss that and you’re collecting tax you haven’t told anyone about, which is an expensive place to be.
Provincial taxes are separate. BC, Saskatchewan and Manitoba each have their own PST or RST, and the CRA doesn’t collect it. Quebec’s QST is handled by Revenu Québec. One business selling in four provinces can end up with four accounts. We haven’t confirmed the registration rules for the provinces other than Quebec, so check the provincial site of each one where you sell.
What does a cross-province invoice look like?
Say you sell equipment for $2,500 before tax. The GST/HST calculator gives $325.00 of HST in Ontario, for a total of $2,825.00. In Alberta it’s $125.00 of GST and $2,625.00. For Quebec, the GST and QST calculator shows $125.00 of GST and $249.38 of QST, a total of $2,874.38.
That’s a $249.38 spread on one product. If your price list is tax-included, your margin moves by province unless you adjust. The reverse HST calculator shows what’s left of a tax-included price after the tax comes out, for example $1,000 of price from a $1,130 Ontario total.
Where do businesses get this wrong?
Usually in a few dull places. One rate on every invoice, because the billing software was set up for the home province. A rate table that still says 15% for Nova Scotia, when the HST there dropped to 14% on 1 April 2025. Tax-included prices that nobody split into base and tax. Each of these is a spreadsheet fix, not a legal puzzle.
Our BC figure needs a warning too. The GST/PST calculator applies 12% to everything, but BC’s PST doesn’t cover all goods and services, so it will overstate the tax for exempt items. It’s fine as a quick estimate for taxable goods. It’s the wrong tool for a mixed invoice.
What records should you keep?
The CRA says to keep GST/HST records for six years after the end of the year they relate to. That means sales and purchase invoices, receipts, bank statements and anything else that supports a return. Keep them somewhere you can reach them quickly, on paper or on disk. If you’d like to dispose of them early, you need to ask your tax services office in writing and wait for the answer.
A simple habit helps: once a quarter, pick five invoices from different provinces and check the rate against the table. It takes twenty minutes. And if you want to see what a review would check, our guide to a sales tax compliance audit goes through the steps, and the rates by province guide explains the layouts in the table.
Where do the numbers come from?
Rates and the $30,000 small supplier limit come from the Canada Revenue Agency, and the records rule from its record keeping pages. BC, Saskatchewan and Quebec tax rates come from the provincial governments. We rechecked them on 29 September 2026. The Manitoba 7% rate is the one figure we’d double check on the province’s site, and we left it out of the table. This website has no link with the CRA or any government.
Frequently asked questions
When must I register for the GST/HST?
Once you pass $30,000 of taxable sales over four calendar quarters in a row, or in a single quarter. You then have 29 days from your effective date to register.
Does the province where I sell change the GST/HST rate?
Yes. Rates depend on the place of supply, which can be the buyer's province or yours depending on the kind of sale. The CRA explains the rules for each type.
Is PST part of the GST/HST return?
No. BC, Saskatchewan and Manitoba run their own PST or RST, and Quebec's QST goes through Revenu Québec.
How long do I keep GST/HST records?
Six years after the end of the year they relate to. To destroy them sooner, ask your tax services office in writing first.
Did the Nova Scotia HST rate change?
Yes. It went from 15% to 14% on 1 April 2025, and the CRA's rate page shows the current rate.
