T4 form

The T4 slip is the year-end document that an employer provides to each employee and to the federal government (the CRA). It summarizes the wages paid and the amounts withheld during the year: income tax, QPP contributions (CPP elsewhere), and employment insurance. In Quebec, it is issued alongside the provincial RL-1.

At a glance

A federal document that summarizes your salary and the amounts withheld over the course of the year
Deductions: Income Tax, QPP Pension Plan, and Unemployment Insurance
Submitted to the employee and the Canada Revenue Agency no later than the last day of February
In Quebec, it is always accompanied by RL-1 (the provincial form)
A late or incorrect T4 form exposes the employer to penalties from the CRA: it’s best to file it on time and ensure it matches the RL-1

Why it matters

If you pay yourself a salary from your own company, you’re serving as both an employer AND an employee. You must therefore file your own T4 (and your RL-1 in Quebec). This document enables each employee to file their taxes: any delay or error will directly affect them. The deadline for the 2025 tax year is March 2, 2026 (normally the last day of February).

Specifically, for a salary of $50,000, the T4 includes federal income tax withheld and contributions to the QPP (approximately $2,930, or 6.30% after the $3,500 basic exemption) and employment insurance. The rules and dates are published by the Canada Revenue Agency.
