Line 308 - CPP or QPP contributions through employment

Data entry links and information

Q: Why does only $1,910.70 (in 2006) appear on line 308? I had two jobs and my total CPP/QPP contributions were higher than that.

A: The maximum contribution for CPP/QPP is $1,861.20. Any contributions in excess of this amount are reported on line 448 of your return.

Q: I have CPP/QPP contributions per my T4 slip but line 308 is blank. Why?

A: The amount appearing on line 308 is calculated based on information you have entered from your T4 slip. If box 26 of your T4 is blank, DO NOT enter "0.00" in that T4 entry field, simply leave it blank. Verify T4 and employment income > T4 > Box 26 - CPP/QPP pensionable earnings (or RL-1 box G - pensionable earnings under the QPP).

Q: Why do I have different QPP contributions on my federal and provincial returns?

A: The CRA and the MRQ use different methods to calculate the allowable QPP contribution. It is therefore possible to have different QPP contributions on your federal and provincial returns.


 Line 308 - CPP or QPP contributions through employment

Claim, in dollars and cents, the total of the Canada Pension Plan (CPP) or Quebec Pension Plan (QPP) contributions shown in boxes 16 and 17 of your T4 slips. Do not enter more than $1,910.70.

If you contributed to the QPP in 2006 but lived outside Quebec on December 31, 2006, treat those contributions as if you made them to the CPP. Attach to your paper return the RL-1 slip your employer sent you.

If you contributed more than $1,910.70, enter the excess amount on line 448 of your return. The CRA will refund this overpayment to you, or use it to reduce your balance owing. However, if you were a resident of Quebec on December 31, 2006, and contributed more than $1,910.70, claim the overpayment on your provincial income tax return for Quebec.

You may have an overpayment, even if you contributed $1,910.70 or less. For example:

You can calculate your overpayment, if any, using Form T2204, Employee Overpayment of 2006 Canada Pension Plan Contributions and 2006 Employment Insurance Premiums.

Request for refund of CPP contributions

Under the Canada Pension Plan Act, a request for a refund of CPP over-contributions must be made within four years after the end of the year for which the request is being made.

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 you were required. This can happen if any of the following applies:

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 $1,910.70, you can contribute 9.9% on any part of the income on which you have not already made contributions. The maximum income for 2006 for which you can contribute to the CPP is $42,100. Making additional contributions may increase the pension you receive later.

To make additional CPP contributions for 2004, complete Schedule 8 to calculate the amount of the additional contributions and claim the appropriate amounts at lines 222 and 310. Also, complete Form CPT20, Election to Pay Canada Pension Plan Contributions, and attach a copy of Schedule 8 and form CPT20 to your paper return, or send it to the CRA separately on or before June 15, 2008. This form lists the eligible employment income on which you can make additional CPP contributions.

Tax-exempt employment income earned by a registered Indian -
If you are a registered Indian with tax-exempt employment income, and there is no amount in box 16 of your T4 slip, you may be able to contribute to the CPP on this income. See "Making additional CPP contributions"; for details.
