When to stop deducting CPP contributions

When you receive a signed and completed election form (CPT30) from an eligible employee, you should stop deducting CPP contributions as of the employee’s first pay in the month after the month the employee signed and dated Part C of the election form.

Note

You may need to prorate the employee’s CPP basic exemption and maximum CPP contributions for the year for an employee 65 years of age or older who elects to stop contributing to the CPP part way through the year. For more information, go to Examples on how to prorate the maximum contribution to CPP.
