How to calculate Ontario sales tax (step-by-step)
Ontario HST = 13% (fixed since 2010, unchanged for 2026). Multiply pre-tax price × 0.13 to get tax amount.
Total payable = pre-tax amount + (pre-tax amount × 0.13). Example: $200 + $26 = $226.
To find pre-tax price from total: divide total amount by 1.13. Ideal for receipts and tax returns.

Special scenarios: business input tax credits & car sales
If you’re a registered GST/HST registrant in Ontario, you can claim Input Tax Credits (ITCs) for the HST paid on business expenses. Our calculator helps you determine the exact provincial/federal portion breakdown. Meanwhile, when purchasing a vehicle from a dealership, HST is applied to the sale price (including any trade-in deduction?). However, private sales: you must self-assess HST at the time of registration. Use our car sales tax calculator ontario mode – simply input the vehicle's purchase price to know the exact tax due at ServiceOntario.
