GST/HST deadline calendar generator: build 12 months of filing reminders.
Start with one reporting period end confirmed in your CRA account. Generate the next 12 monthly periods, four quarterly periods, or one annual period, then download filing and payment reminders in a calendar file that works without an account.
One portable schedule
What the GST/HST calendar includes.
The generator uses the ordinary deadline paths currently published by CRA and keeps the evidence needed to verify each reminder.
Payment and filing kept separate
Most paths use one date. A qualifying December 31 sole proprietor instead receives separate April 30 payment and June 15 filing reminders.
Nominal dates remain visible
A weekend produces a next-weekday candidate, but the export preserves the nominal CRA-rule date and tells the user to check recognized holidays.

Primary sources
The live CRA rules stay beside the download.
CRA says the account shows the filing due dates and reporting periods. It also applies a next-business-day rule when a due date falls on a weekend or recognized public holiday. This generator screens weekends only.
Calendar questions
GST/HST deadline calendar FAQ.
Can I download a GST/HST deadline calendar for 2026 or 2027?
Yes. Enter the first reporting period end for the schedule shown in your CRA account. The generator is date-driven rather than tied to one calendar year, so the reminders can cross from 2026 into 2027.
How many GST/HST reminders does the file contain?
It contains 12 monthly periods, four quarterly periods, or one annual period. A period with the same payment and filing date produces one event; a qualifying sole-proprietor annual period produces two.
Does the calendar include GST/HST instalments?
No. This calendar covers return and final-payment deadlines derived from reporting periods. Annual-filer instalments use a separate calculator and schedule.
Does the generator move dates for Canadian holidays?
No. It shows a next-weekday candidate when the nominal date falls on Saturday or Sunday. CRA-recognized federal, provincial, and territorial holidays still require a live check.
Are my reporting dates sent to Thirty North?
No. The calculation and downloads run in the browser. No account is required, and the dates are not uploaded or stored by Thirty North.
Will the calendar file submit my GST/HST return or payment?
No. The events are reminders marked for confirmation. The tool does not access a CRA account, file a return, schedule a payment, or determine whether another rule applies.
Educational scope
Check one period insteadUse the CRA account as the final calendar.
The generator does not detect period changes, short periods, instalments, public holidays, special returns, relief, account credits, QST dates, filing receipt, payment receipt, or another fact-specific exception. Use the single-date calculator when you need to inspect only one confirmed period.
