If you are 60 to 70 years of age, employed or self-employed, and you are receiving a CPP or QPP retirement pension, you must make contributions to the CPP or the QPP.

However, if you are at least 65 years of age but under 70, you can elect to stop contributing to the CPP or revoke a prioryear election. For more information, see Form CPT30, Election to Stop Contributing to the Canada Pension Plan, or Revocation of a Prior Election, and Schedule 8 or Form RC381, whichever applies.

Making additional CPP contributions

You may not have contributed to the CPP for certain income you earned through employment or you may have contributed less than required. This can happen if any of the following apply:

Generally, if the total of your CPP and QPP contributions through employment, as shown in boxes 16 and 17 of your T4 slips, is less than $2,593.80, you can contribute 9.9% on any part of the income on which you have not already made contributions. The maximum income for 2018 on which you can contribute to the CPP is $55,900.

To calculate and make additional CPP contributions for 2018, complete Form CPT20, Election to Pay Canada Pension Plan Contributions, and Schedule 8 or Form RC381, whichever applies. Form CPT20 lists the eligible employment income on which you can make additional CPP contributions.
