Frequently Asked Questions
How do I add these to my phone calendar?
Add each date with a reminder set 2 weeks in advance. For April 30 and June 15, set a 30-day reminder as well. Google Calendar and Apple Calendar both support recurring annual events — once set up, these reminders recur every year without manual re-entry.
What if I am a quarterly GST/HST filer — does the calendar change?
For quarterly GST/HST filers, the four remittance due dates are: April 30, July 31, October 31, and January 31. These are independent of the income tax calendar and remain constant year to year.
Is the RRSP deadline always 60 days after December 31?
Yes. The RRSP deadline is always the last day of February, or if February 28 falls on a weekend, the following business day (typically March 1 or 2). The CRA confirms each year’s exact RRSP deadline in the fall — verify at canada.ca.
