Inter-Provincial Calculation for CPP and QPP Contributions and Overpayments
 
The Canada Pension Plan (CPP) and Quebec Pension Plan (QPP) were amended to provide for the enhancement of pensions.
The enhancements are funded by additional contributions that began in January 2019.
 
As of January 2024, a second additional contribution is required on pensionable earnings that are more than the year's
maximum pensionable earnings but not more than the year's additional maximum pensionable earnings.
Your CPP and QPP contributions consist of a base amount, first additional amount and second additional amount. The
contributions that you are required to make are determined by your total amount of pensionable earnings for the year.
Your employer will have already deducted the contributions from your salary or wages. As a self-employed individual, you will
calculate your required contributions (if any), including the base, first and second additional amounts, on this form.
The CPP and the QPP have different base contribution rates. The Canada Revenue Agency (CRA) must be able to calculate
your CPP and QPP contributions separately using the applicable rate(s).
 
The CRA will use the information from this form to calculate the portion of the year's basic exemption and the maximum
contributory earnings to be applied to the CPP and QPP.
 
For more information about the enhancements, go to canada.ca/cpp-enhancement or revenuquebec.ca/en.
For more information about lines 22200, 22215, 30800, and 31000, go to canada.ca/fed-tax-information.

  However, if you were at least 65 years of age, but under 70 years of age, you can elect to stop paying CPP contributions.

in 2024. An election made using Form CPT30 applies to all income from pensionable earnings, including self-employment
earnings, as of the first day of the month after the date you gave this form to your employer.

paying CPP contributions or revoke an election made in a previous year on your self-employment income before you
became employed, enter the month you want to stop paying CPP contributions on line 50372.

June 15, 2026, to be valid.
