  T1-2023 Canada Pension Plan
Contributions and Overpayment		 Schedule 8   
 
  The Canada Pension Plan (CPP) was amended to provide for the enhancement of pensions. The government of Quebec also
adopted legislative amendments to enhance the Quebec Pension Plan (QPP) in a similar way as the federal plan.
The enhancements are funded by additional enhanced contributions that began in January 2019.
  The contributions consist of a base amount and an enhanced amount. Your employer will have already deducted the
contributions from your salary and wages. As a self-employed individual, you will calculate your required contributions (if any)
on this schedule including the base and enhanced amounts.
  For more information about lines 22200, 22215, 30800 and 31000, go to canada.ca/fed-tax-information.

  Complete this schedule to calculate your required CPP contributions or overpayment for 2023 if you were a resident of a
province or territory other than Quebec on December 31, 2023, and you have no earned income from the province of Quebec.
Attach a copy of this schedule to your paper return.

Calculation for CPP and QPP Contributions and Overpayments.
