Ontario sales tax rate in 2026
Ontario uses the Harmonized Sales Tax (HST), a single combined rate of 13% made up of the 5% federal portion and a 8% provincial portion. The CRA collects it as one tax, so you see a single 13% line on receipts.
On common amounts at 13%: $10 → C$1.30 tax (C$11.30 total) · $50 → C$6.50 tax (C$56.50 total) · $100 → C$13.00 tax (C$113.00 total) · $1,000 → C$130.00 tax (C$1130.00 total).
