T4 (Statement of Remuneration Paid)
The T4 slip is issued by employers to employees by the last day of February each year. It reports total employment income, income tax deducted at source, CPP contributions, EI premiums, and any other deductions or taxable benefits for the previous calendar year.
Key boxes on the T4 include: Box 14 (employment income), Box 16 (CPP pensionable earnings), Box 22 (income tax deducted), Box 24 (EI insurable earnings), and Box 52 (pension adjustment, if applicable). You use these figures to complete your T1 income tax return.
If you have multiple employers during the year, you'll receive a T4 from each. Other income types have their own slips: T4A (pension, self-employment commission), T4E (EI benefits), T3 (trust income), T5 (investment income), and T5007 (social assistance or workers' compensation). All slips are available electronically through CRA My Account.
