What is a T4 preview?
Available November 1st, the T4 preview slips are a preview of what your employees’ T4 slips will look like based on pay and benefits issued so far in 2024. This allows you to review the wage, tax, employee and business details to ensure forms are filed accurately, without the need for corrections later on.
The information you view in the T4 preview reflects current year-to-date payroll information on the day you preview it. If you’ve approved a payroll with a payday in the future, the pay and benefits it includes will appear on previews generated after the payday has passed.
How do I preview my T4 slips?
The preview contains 2024 T4 slips for each of your employees, and your 2024 T4 Summary. It reflects only wages and benefits paid up to the date it is generated. Do not use these forms for filing. The final versions will be available February 2025.
