Canada Pension Plan (CPP)

• All employees between the ages of 18 and 70 are subject to CPP deductions
• The deduction rate and the annual maximum contributions are established by CRA and vary yearly
• If an employee is in receipt of a Canada Pension Benefit, and are over the age of 65, and wishes to be CPP exempt (i.e. CPT30 form), proof must be presented in Payroll Services before this change can be made.

Canada/Quebec Pension Plan (CPP) Enhancement Contribution

In 2025, all employees pay CPP contributions (at 5.95%) on earnings up to the Year’s Maximum Pensionable Earnings (YMPE $71,300). In addition, employees who earn more than $71,300 per annum will continue to make CPP contributions at a rate of 4% until they reach the YAMPE of $81,200. The pay bracket between $71,300 and $81,200 is known as the Year’s Additional Maximum Pensionable Earnings (YAMPE $81,200).  

Example; an employee who earns $78,000 annually will contribute to CPP at a rate of 5.95% on the first $71,300 of their earnings. They will continue to contribute to CPP at 4% up to the $81,200 (YAMPE). There are no CPP contributions payable on earnings over $81,200. The additional CPP contribution (in this example) is $396.00 ($81,200 – $71,300 = $9,900 x 4% = $396).

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
