T4 T4 |

The T4 slip is the year-end document that an employer provides to each employee and to the federal government (the IRS). It summarizes the salary paid and the amounts withheld during the year: income tax, pension plan contributions (QPP in France, CPP elsewhere), and employment insurance. In Quebec, it is used in conjunction with the provincial Relevé 1 slip.

Brief

Federal document summarizing salary and amounts withheld over the year
Deductions: tax, social security and unemployment insurance;
Submitted to the employee and the IRS (Internal Revenue Service) Canada ) no later than the last day of February;
In Quebec, it is always accompanied by the Relevé 1 (the provincial slip)

Why does this matter?

If you pay yourself a salary from your own business, you play two roles: employer AND employee. Therefore, you must file your own T4 slip (and your Relevé 1 in Quebec). This document allows each employee to file their taxes: a delay or error directly penalizes them. The deadline for 2025 is March 2, 2026 (normally the last day of February).
