How GST/HST Is Calculated
In HST provinces (ON, NB, NS, NL, PE), the federal GST and provincial portion combine into a single rate that applies to the same calculation. In split-rate provinces (BC, MB, QC, SK), GST and PST/QST are calculated separately on the net price and added together.
Adding Tax (e.g. Ontario 13% HST)
For HST provinces, multiply by 1 plus the rate to find the tax-inclusive total. The same logic applies to GST-only provinces using 1.05.
Total = Price × 1.13
Example: CAD 100 × 1.13 = CAD 113.00
Extracting Tax (e.g. Ontario 13% HST)
Divide a tax-inclusive total by 1 plus the rate to recover the net price — or take 13/113 to find the tax portion directly in HST provinces.
Tax = Total × 13/113
Example: CAD 113 ÷ 1.13 = CAD 100.00
What Is (and Isn't) Subject to GST/HST
Most goods and services in Canada are standard-rated at the applicable provincial rate. Two categories sit outside the standard rate: zero-rated (where input tax credits remain claimable) and exempt (where credits cannot be claimed). Notably, basic groceries are zero-rated in Canada — unlike NZ where almost all food is taxed.
Zero-Rated (0%) Supplies
- ✓Basic groceries (bread, milk, vegetables, meat)
- ✓Prescription drugs and most medical devices
- ✓Exports of goods and services
- ✓International passenger transportation
- ✓Most agriculture and fishing products
Exempt Supplies (No ITCs)
- –Residential rent and long-term accommodation
- –Most health and dental services
- –Child care services
- –Most educational services
- –Most financial services
GST/HST Filing Cycles & Due Dates
The CRA assigns a reporting period based on annual taxable supplies. Returns and payments are generally due by the last day of the month following the reporting period. Late filing attracts a penalty of 1% of the amount owing plus 0.25% per full month outstanding (max 12 months — capping additional penalty at 4%). Daily compounded interest applies to all unpaid amounts at the CRA prescribed rate.
| Filing Cycle | Who It Applies To | Due Date |
|---|---|---|
| Monthly | Annual taxable supplies above CAD 6 million | Last day of following month |
| Quarterly | Annual taxable supplies CAD 1.5M – 6M (or elected) | Last day of month after quarter end |
| Annual | Annual taxable supplies under CAD 1.5 million (default) | 3 months after fiscal year end |

Frequently Asked Questions
Common questions about Canadian GST/HST — federal and provincial rates, registration, zero-rated and exempt supplies, filing deadlines, and Input Tax Credits — answers verified against official CRA guidance.
Important Disclaimer
For educational and informational purposes only. This calculator produces estimates based on the inputs provided and the official Canada Revenue Agency (CRA) GST/HST settings. The federal GST rate is 5% and applies in all provinces and territories. The HST is charged in Ontario (13%), New Brunswick (15%), Newfoundland and Labrador (15%), Prince Edward Island (15%), and Nova Scotia (14% — reduced from 15% on 1 April 2025). British Columbia (7% PST), Manitoba (7% RST), Saskatchewan (6% PST) and Quebec (9.975% QST) charge a separate provincial sales tax in addition to the 5% federal GST. The compulsory registration threshold is CAD 30,000 in taxable revenues over a single calendar quarter or rolling four quarters. Late filing where a balance is owing attracts a 1% penalty plus 0.25% per full month outstanding (capped at 12 months). Daily compounded interest applies to all overdue amounts at the CRA prescribed rate.
