The direct answer
Use CRA-certified T2 software and a supported corporate filing service, such as Corporation Internet Filing. For tax years starting after 2023, most corporations must file electronically, with specified exceptions. A simple return or low income does not by itself create an exemption. A printed bar-coded return remains paper filing and can attract the mandatory electronic-filing penalty when the requirement applies.
Confirm the return and filing route
Use the corporation's legal details, tax year-end and CRA account information to establish the filing requirements. The online submission process follows preparation of the complete return and schedules. It does not turn a rough profit total into a finished T2. Have the reconciled books, prior balances and supporting information ready before deciding the file is ready for transmission.
Keep preparation, approval and filing distinct
Review the completed return and any required authorization before it is sent. After filing, retain the confirmation and submitted version rather than assuming a saved software file proves CRA received it. If the transmission fails, record the error and resolve it. A printed copy and an electronic submission are different records with different purposes.
What to gather before the review
- Corporate identification and exact fiscal period
- Reconciled books and prior tax information
- Required authorization and final filing confirmation
Can a simple corporation automatically choose paper filing?
No. A small or straightforward return does not by itself create an exception to mandatory electronic filing. Check the corporation's category and tax year before selecting the permitted method.
Your next step
Confirm the corporation’s filing category and tax year, then give the preparer reconciled books and the required authorization.
