This schedule calculates the amount of Canada Pension Plan (CPP) contributions you must pay if you reported self-employed, business or professional income on your tax return. There is a separate schedule for Quebec residents who must pay into the Quebec Pension Plan (QPP) instead of the CPP.

If you’re between 65 and 70 years old and self-employed and no longer want to contribute to CPP, then you can use this form to elect to stop contributions.

You can also use the Schedule 8 to make voluntary CPP contributions on income which would not otherwise be subject to CPP contributions, such as tips.
