T4 – Information for employers
For the tax year 2020, in addition to reporting employment income in Box 14 or Code 71, use new other information codes for periods from March 15 to September 26, 2020.
Generally, you need to fill out a T4 slip if you are an employer (resident or non-resident) and you paid your employees employment income, commissions, taxable allowances and benefits, fishing income, or any other remuneration. For more information, go to What to report and what not to report on T4 slips.
If you are an employee who has not received your T4 slip or you have questions about amounts, contact your employer or go to Tax slips.
