GST/HST and QST Filing and Assessment Periods

Notes

(1) Taxable supplies include those that are zero-rated. Some supplies, however, may be 

excluded for the purpose of these calculations.

(2)  In order to use the optional reporting period, an election must generally be filed at the start 

of the year.

(3) For GST/HST and QST reporting, an individual with an annual reporting period, with 

business income and a December 31 year-end, must pay by April 30 and file by June 15.

(4) The assessment is generally 4 years, however this period may be extended if there is fraud 

or misrepresentation attributable to neglect, carelessness or wilful default.
