Self Employment CPP


Recommended Posts



I'm completing a return for my daughter. I'm getting the following error message and I don't know what to do about it. Can someone please help?


"You have CPP contributions on self-employment and other earnings with CPP contributions on employment income. The result of the CPP contributions payable on self-employment and other earnings of Schedule 8 is negative. You may have an overpayment. In this situation, the CRA does not want an amount on line 448 and wants to calculate it for you."

Thank you

You will find the answer in Schedule 8.

Go to Part 5, line 23.

You are probably in a situation of CPP overpayment.


CRA refuses to let a software calculate the overpayment.

They will advise you in your Notice of assessment.


You have nothing to change in your data.

The diagnostic is there to warn you about the situation.
