A gross receipts tax is a tax on a business’s total sales, with no deduction for what it cost to earn them. Canada doesn’t have one under that name on the CRA pages we read. Businesses here deal with three different taxes instead: GST/HST on sales, income tax on profit, and payroll contributions.
What is a gross receipts tax, and why do people search for it?
The term comes mostly from the United States, where some states and cities charge a small percentage of a company’s revenue. It hits a business that loses money as hard as one that makes a fortune, because costs never come off. That one feature is why people dislike it.
If you’re a Canadian owner reading a US article, you’ll want to know which of our taxes looks closest. None matches exactly. Two of them do touch your gross sales, though, and it helps to see which.
Which Canadian taxes look at your total sales?
The table shows what each tax is measured on. Only the first two are set by reference to sales at all.
| Tax | What it’s charged on | Are costs deducted? |
|---|---|---|
| GST/HST | Taxable sales, at the rate for the province (13% HST in Ontario) | Registrants recover the tax they paid on business costs through input tax credits |
| Registration threshold | Revenue over $30,000 across four calendar quarters, for most small suppliers | No, it looks at revenue |
| Income tax (person or corporation) | Profit after expenses | Yes |
| CPP and EI | Pay, or net self-employed earnings | Not applicable |
How does GST/HST differ from a gross receipts tax?
You charge it on your sales, but you don’t keep it. It’s remitted to the government, and since the CRA says registrants recover the GST/HST paid on purchases for their commercial activities by claiming input tax credits, the tax ends up sitting on the final customer rather than on you.
Take a shop in Ontario with $100,000 of taxable sales. At 13% it collects $13,000. If it spent $40,000 on taxable supplies, it paid $5,200 of HST on those purchases and claims that back. It sends in $7,800. Under a true gross receipts tax, the full $13,000 would have been the bill. The GST/HST calculator does the arithmetic for a single sale, and the HST reverse calculator backs the tax out of a price that already includes it.
Provinces with a separate sales tax are a bit different. In British Columbia, Saskatchewan and Manitoba the provincial tax sits beside the 5% GST, and in Quebec the QST does. If you sell there, the GST and PST calculator shows how the two stack.
When do you have to register?
Most small businesses don’t have to register until revenue passes $30,000 over four consecutive calendar quarters. The CRA counts a single quarter too, so one big quarter can tip you over. Once you cross it, the CRA says to start charging on your effective date and to register within 29 days of it.
Picture Dana, who sells handmade candles at weekend markets. A quiet spring, then a huge December, and suddenly her last four quarters add up to more than $30,000. The month she crosses the line matters, so she should add up her quarters now and then, not wait for tax time.
There are exceptions. Taxi and rideshare drivers must register even when they’re small. If you’re near the line, work out your quarterly revenue now, not after the fact.
What does income tax take on the same business?
Income tax works on what’s left. Say the shop’s $100,000 of sales leaves $30,000 of profit in an Ontario corporation. The corporate tax calculator shows about $3,509, or 11.7% of that profit. That figure blends a mid-year change in the Ontario small business rate, so treat it as an estimate. The same firm with a lost year would owe no income tax, but it would still charge HST on every sale.
A sole proprietor doesn’t pay corporate tax. The profit goes on a personal return, where the self-employed tax calculator gives a first estimate. It counts deductions against income tax only and leaves out EI, so the total is close but not exact.
So does Canada have a gross receipts tax or not?
Not a general one. The nearest thing is the way GST/HST is measured on sales, and even that lets you claim back what you paid on costs. A municipality or province might charge some local levy we haven’t covered, so if you operate in a place with unusual business fees, ask the city or the province directly.
Mistakes to avoid
Don’t treat HST collected as your revenue. It isn’t yours, and spending it is how small firms end up short at remittance time. Park it in a separate account.
Don’t assume a US rule applies here. We looked at the CRA pages, not at every municipal or provincial rule.
And don’t confuse the $30,000 registration threshold with a tax. It’s a line for when you start charging, nothing more.
Where this information comes from
The $30,000 small supplier threshold, the 29-day registration rule and input tax credits come from Canada Revenue Agency GST/HST pages, read in September 2026. The 13% Ontario HST rate is from the CRA rate table. Income tax figures come from this site’s 2026 calculators. We aren’t a government service and we don’t speak for one.
Frequently asked questions
Does Canada have a gross receipts tax?
Not under that name on the CRA pages we read. GST/HST is charged on sales, but registrants claim back the tax they paid on business costs.
Is GST/HST a tax on my revenue?
You collect it on taxable sales, but input tax credits let you recover what you paid on business purchases, so it isn't a cost of the business in the usual case.
When must a small business register for GST/HST?
For most small suppliers, when revenue passes $30,000 in a single quarter or over four consecutive calendar quarters.
Are there registrants who must register anyway?
Yes. The CRA says taxi and rideshare drivers must register even as small suppliers.
Does a loss year mean no tax at all?
You'd owe no income tax on a loss, but GST/HST still applies to your taxable sales.
