2. In the Tasks pane, right-click the Employees icon and select Modify Employee from the menu.
3. Select an employee from the list and click OK.
4. In the Personal tab, verify the Birth Date.
   • If the Birth Date of the employee is in the middle of the year, the CPP deductions to zero will not take effect until the employee is over the age of entitlement for the full paycheque period

If the age (Birth Date) was incorrect:

1. Correct the Birth Date.
2. If paycheques have already been posted:
   1. Do the following steps at the end of the calendar year and after the final paycheque:
   2. Click the T4 and RL-1 Reporting tab.
   3. On the Pensionable earnings line, enter the correct amount.
