Questions
Do contractors charge HST on labour?
Yes. In Ontario, Nova Scotia, New Brunswick, Newfoundland and Labrador and Prince Edward Island, HST applies to the whole price of the job, labour and materials, once you are registered for GST/HST.
When do I have to register for GST/HST?
Once your taxable sales pass $30,000 over four calendar quarters in a row, you have to register and start charging it. Under that you are a small supplier, and registering is up to you.
How do I take the HST out of a total?
Divide the total by 1 plus the rate. In Ontario, $1,130 divided by 1.13 is $1,000 before tax, so the HST was $130. Switch the calculator to Remove Tax and it does this for you.
Do I charge PST in BC, Manitoba or Saskatchewan?
It depends on the job and the province. PST rules for contractors work differently from GST, and some jobs are taxed on the materials you buy instead of on the price you charge. Check your province's rules, then turn PST on or off in the calculator.
How does sales tax work in Quebec?
Quebec charges GST at 5% and QST at 9.975%, both on the price before tax, for 14.975% in all.
Which province's tax do I charge?
The tax of the province where the job is, not where your business is. Work on a house in Gatineau gets Quebec's tax even if your shop is in Ottawa.
This calculator does the math, not tax advice. For your own situation, ask your accountant or the Canada Revenue Agency.
