How GST/HST Is Calculated
Canada's tax system differs by province. In HST provinces (Ontario, NB, NS, NL, PEI), the federal GST and provincial portion are combined into one Harmonized Sales Tax. In other provinces, GST and PST/QST are calculated and collected separately.
Tax Amount = Price × 0.13
Total = Price × 1.13
Example: $100 × 1.13 = $113.00
Base Price = Total ÷ 1.13
Tax Amount = Total − Base
Example: $113 ÷ 1.13 = $100.00
Split-rate provinces (BC, MB, QC, SK): GST (5%) and PST/QST are calculated separately on the net price and then added together. For example, in British Columbia: GST = Price × 0.05, PST = Price × 0.07, Total = Price × 1.12.

GST/HST Filing Deadlines
The CRA assigns a reporting period based on your annual taxable supplies. Returns and payments are generally due by the last day of the month following the reporting period. Late filing incurs a 1% penalty plus an additional 25% of the 1% for each month the return is outstanding, up to 12 months.
| Filing Frequency | Who It Applies To | Due Date | Example |
|---|---|---|---|
| Monthly | Annual taxable supplies > CA$6 million | Last day of following month | Jan return due Feb 28 |
| Quarterly | Annual taxable supplies CA$1.5M–$6M (or elected) | Last day of month after quarter end | Jan–Mar return due Apr 30 |
| Annual | Annual taxable supplies < CA$1.5 million (standard) | 3 months after fiscal year end | Dec 31 FY end → due Mar 31 |
Key Quarterly Filing Due Dates
* Individuals with a December 31 fiscal year end have until June 15 to file, but any amount owing is still due April 30. Always confirm due dates with CRA or your accountant.

Federal GST Rate History
Canada introduced the federal Goods and Services Tax on 1 January 1991 under the Mulroney government, replacing the previous Manufacturers' Sales Tax. The rate was reduced twice under the Harper government and has remained at 5% since 2008.
HST harmonization history: Ontario and BC joined the HST system in 2010. BC later reversed this in 2013 following a referendum. Nova Scotia reduced its HST from 15% to 14% on 1 April 2025. PST rates in other provinces are set independently and can change separately from the federal GST.
