Do not put every obligation on one date
The CRA generally requires a corporation income tax return to be filed within six months after the end of the tax year. That filing rule should not be used as a shortcut for determining when a tax payment is due. Consult the CRA’s separate payment guidance and your accountant for the corporation’s actual obligations.
A calendar that says only “corporate tax due” can hide important distinctions. Keep separate entries for return preparation, balance payments, instalments and any related information returns.
Build the calendar from your corporation’s facts
Confirm the fiscal year-end and keep the latest CRA account information available. Tell the accountant about changes in the business, outstanding returns and any notices received. Do not assume that a calendar built for another corporation is the right one for yours.
Where a CRA filing deadline falls on a Saturday, Sunday or recognized public holiday, the CRA describes an on-time rule for the following business day. Check the official guidance for the actual due date rather than relying on a date calculated in a generic spreadsheet.
Leave time for the records
Preparing a return may require reconciled books, supporting schedules and an explanation of significant transactions. Identify the last completed bookkeeping period and ask how much cleanup is needed. The filing deadline is not an ideal first-contact date when the records are incomplete.
Ask for a clear division of responsibilities
Confirm who prepares the return, who authorizes submission, who arranges a payment and how the amount will be communicated. Request clarity about the scope of instalment or notice support rather than assuming every subsequent obligation is included.
