Employers – Important CPP and EI Deadlines

Employers – Important CPP and EI Deadlines

Employers must file CPP and EI refund applications by December 31.

These applications can be used to claim certain overpaid CPP contributions or EI premiums. Some of these overpaid contributions may be related to amounts, including certain payments and benefits, which are excluded from CPP contributions and EI premiums. If an employer has remitted CPP and EI on such amounts, or on amounts exceeding the maximum insurable earnings or pensionable earnings, the employer may be eligible to claim a refund if a refund application is filed within specific time limits.

As a result, an employer has one last chance to file a refund application by December 31, 2017 for eligible CPP contributions overpaid in 2013. In addition, employers have until December 31, 2017 to file a refund application for EI premiums overpaid in 2014.

In general, overpaid amounts related to the current year will be adjusted on the employers' payroll records. For overpayments related to prior calendar years, a taxpayer can file a refund application to the CRA within the following time frame:

  • CPP contributions - No later than four years from the end of the year in which the overpayment occurred
  • EI premiums - No later than three years from the end of the year in which the overpayment occurred
  • Overpayments refundable due to a CRA or court decision - No later than 30 days after the decision is communicated to the employer or the employee.

When the employer files a refund application, only the employer portion of the EI premiums or CPP contributions are refunded. In certain circumstances, the employer may have to issue an amended T4 for the applicable taxation years if the employee has also overpaid. Where an amended T4 is issued, the employee will then have to adjust their previously filed tax returns based on the revised T4, which will then trigger a refund of the overpaid EI premiums or CPP contributions.
