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. As an employee, 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 the enhanced amounts.

For more information, see lines 22200, 22215, 30800, and 31000 of the Federal Income Tax and Benefit Guide.

Find out if this schedule is for you

Complete this schedule to calculate your required Canada Pension Plan (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.

Do not complete this schedule if any of your T4 slips show Quebec Pension Plan (QPP) contributions. Instead, complete Form RC381, Inter-provincial Calculation for CPP and QPP Contributions and Overpayments.

Parts you need to complete

Part 1 -	Complete this part if you are electing to stop contributing to the CPP or you are revoking a prior election.

Part 2 -	Complete this part to determine the number of months for the CPP calculation.

Part 3 -	Complete this part if you are reporting employment income.

Part 4 -	Complete this part if you are reporting only self-employment income or other earnings you are electing to pay CPP contributions on.

Part 5 -	Complete this part if you are reporting employment income and self-employment income or other earnings you are electing to pay CPP contributions on. (You must first complete Part 3.)


If there is a valid election to stop contributing to the CPP or a valid revocation of a prior election to resume contributing to the CPP in effect for 2023, please enter the information below as per the in-effect form CPT30 and/or Schedule 8/RC381:
	Election or revocation?
	Form(s) used to make the in-effect election or revocation
	Effective date to stop contributing to the CPP or effective date to resume contributing to the CPP *
	(You must be at least 65 years of age but under 70 when the election or revocation was made.)	YYYY-MM

*	Note: The date entered on this worksheet is the actual/effective starting date (YYYY-MM) to stop contributing to the CPP or to resume contributing to the CPP (e.g., for CPT30, not the date when form CPT30 was signed, but the first day of the month after the date when form CPT30 was signed.).

Part 1 -

Election to stop contributing to the Canada Pension Plan or revocation of a prior election

You were considered a CPP working beneficiary and were required to make CPP contributions in 2023 if you met all of the following conditions:

You were 60 to 70 years of age
You received a CPP or QPP retirement pension
You had employment income or self-employment income or both

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

Employment income
If you had employment income for 2023 and you elected in 2023 to stop paying CPP contributions or revoked in 2023 an election made in a previous year, you should have already completed and sent Form CPT30, Election to Stop Contributing to the Canada Pension Plan or Revocation of a Prior Election, to the CRA and your employer(s).

Self-employment income only
If you had only self-employment income for 2023 and are electing in 2023 to stop paying CPP contributions on your self-employment earnings, enter the month in 2023 you are choosing to start this election on line 50372 on the next page. The date cannot be earlier than the month you turn 65 years of age and are receiving a CPP or QPP retirement pension. For example, if you turn 65 in June, you can choose any month from June to December. If you choose the month of June, enter "06" on line 50372.

If, in 2023, you are revoking an election made in a previous year on contributions on self-employment earnings, enter the month in 2023 you are choosing to revoke this election on line 50374 on the next page. Your election remains valid until you revoke it or turn 70 years of age. If you start receiving employment income (other than employment income earned in Quebec) in a future year, you will need to complete Form CPT30 in that year for your election to remain valid.

Election to stop contributing to the Canada Pension Plan or revocation of a prior election
(continued)

Employment and self-employment income
If you had both employment income and self-employment income in 2023 and you wanted to elect to stop paying CPP contributions in 2023 or revoke in 2023 an election made in a previous year, you should have completed Form CPT30 in 2023. An election filed 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.

If you completed and sent Form CPT30 when you became employed in 2023 but your intent was to elect in 2023 to stop 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 contributing on line 50372.

If you want to revoke for 2023 an election made in a previous year, enter the month you want to resume contributing on line 50374.

If you did not complete and send Form CPT30 for 2023 when you became employed, you cannot elect to stop paying CPP contributions or revoke an election made in a previous year on your self-employment earnings for 2023 on this schedule.


Note:		If you had self-employment income in 2023, an election or revocation that begins in 2023 must be filed on or before June 15, 2025 to be valid.
