How it works
Three steps, every tax on its own line
- 01
Add or take out
Add tax to a price before tax, or start from a total that already includes tax and find the price inside it.
- 02
Pick the place
Choose the country, then the province, territory, state or region. In the US, add your city or county rate.
- 03
Read each line
Each tax is worked out on the price before tax and rounded to the cent on its own, so the lines match what you put on the invoice.
Good to know
How sales tax shows up on an invoice
GST and HST
GST is the 5% federal tax. Ontario and the Atlantic provinces combine it with their provincial tax into one HST: 13% in Ontario, 14% in Nova Scotia and 15% in New Brunswick, Newfoundland and Labrador, and Prince Edward Island.
PST, RST and QST
British Columbia, Saskatchewan and Manitoba charge their own tax next to GST, and so does Quebec with QST. Each is worked out on the price before tax, never on the GST, and shown as its own line.
US state and local rates
Each state sets a statewide rate, and most cities, counties and districts add their own. The state list shows the statewide rate; add the local rate for where the sale happens.
Mexico IVA
IVA is 16% in most of Mexico. Registered sellers in the northern and southern border regions can charge 8% on many sales under a tax incentive that runs through December 31, 2026.
Taking tax out of a total
The price before tax is the total divided by one plus the rate, rounded to the cent, then checked by adding the tax back. Because each tax is rounded, a few totals cannot come from any price; the calculator then shows the closest one.
Which rate to charge
The rate usually depends on where your client receives the goods or services, and some sales are exempt or taxed differently. Check with the Canada Revenue Agency, your state, or the SAT before you rely on a rate.

What is the sales tax rate in Ontario?
Ontario charges 13% HST, which combines the 5% federal GST and the 8% provincial part. On a $1,200 job the HST is $156.00 and the total is $1,356.00.
How do I take the sales tax out of a total?
Divide the total by one plus the rate. In Ontario, $1,356.00 divided by 1.13 is $1,200.00 before tax, with $156.00 of HST. Choose “Take tax out of a total” and the calculator does it, with each tax line rounded to the cent.
Is QST charged on top of GST?
No. Quebec’s 9.975% QST is worked out on the price before GST, like the GST itself. On $100.00 that is $5.00 of GST and $9.98 of QST, for $114.98.
Does the US calculator include city and county tax?
The state list has the statewide rate only. Type your city, county or district rate in Local rate and it is added as its own line. Your state’s revenue department lists the local rates.
How current are the rates?
Every rate links to the government page we read it from, and the page shows the date we checked. Rates and rules change, so confirm with your tax agency before you rely on one.
Can Sumocat add these taxes to my invoices?
Yes. In the Sumocat app you add one or more taxes, like GST and PST, to any invoice or estimate, and the totals round the same way as this calculator on every device. A free account is all you need.
