Canada Pension Plan (CPP)

Canada/Quebec Pension Plan (CPP) Enhancement Contribution

As a part of the CPP enhancement, additional CPP contributions will be phased in between 2024 and 2025.

In 2024, all employees pay CPP contributions (at 5.95%) on earnings up to the Year’s Maximum Pensionable Earnings (YMPE $68,500). In addition, employees who earn more than $68,500 per annum will continue to make CPP contributions at a rate of 4% until they reach the YAMPE of $73,200. The pay bracket between $68,500 and $73,200 is known as the Year’s Additional Maximum Pensionable Earnings (YAMPE $73,200).  

Example; an employee who earns $78,000 annually will contribute to CPP at a rate of 5.95% on the first $68,500 of their earnings. They will continue to contribute to CPP at 4% up to the $73,200 (YAMPE). There are no CPP contributions payable on earnings over $73,200. The additional CPP contribution (in this example) is $188 ($73,200 – $68,500 = $4,700 x 4% = $188).

The Canada Revenue Agency has created two new additional boxes on the current T4 as follows:

  • Box 16A – for reporting of employees’ second CPP contribution
  • Box 17A – for reporting of employee’s second QPP contribution

Note:  Although you will see the above boxes on your T4, no amounts will be reported on your 2023 T4 slips because the new CPP contribution requirements will only begin in 2024.
