Questions

What is the HST rate in Ontario in 2026?

Ontario HST is 13% (5% federal + 8% provincial).

How do I remove HST from a total?

Divide the total by 1 plus the rate. In Ontario: total ÷ 1.13 = price before tax. The difference is the HST. Choose “Total with tax” above to do it automatically.

When your worldwide taxable sales are more than $30,000 in a single calendar quarter or in the last four consecutive quarters. Until then you are a small supplier.

Ontario (13%), Nova Scotia (14%), New Brunswick, Newfoundland and Labrador and Prince Edward Island (15%). The others charge 5% GST, and some add a separate provincial sales tax.
