On January 6, 2026, the Canada Revenue Agency (CRA) released the updated RC4120, Employer’s Guide – Filing the T4 Slip and Summary. This guide provides employers with instructions on how to accurately prepare and file T4 slips and the T4 Summary, outlining reporting requirements and filing deadlines.
The RC4120 guide includes the changes to the employee stock options.
Employers should:
- Review the updated RC4120;
- Confirm that their payroll systems and processes align with the current CRA guidance and address any gaps before filing deadlines; and
- Ensure that staff responsible for payroll and year-end reporting are aware of the updates and have access to the guide.
