Has Anyone else experienced this where QBO Payroll doesn't add the 2nd CPP for both the Employee and Employer to the T4 Summary Line 82 but adds it on everywhere else?

Hello TTL5,

Welcome to the Community. I'll be happy to guide you in the right direction so you can get the resolution you need. 

Its important to note that QuickBooks adheres to the regulations set by the CRA, especially when it comes to managing the second CPP. For reference, here's how to view the second CPP on your end:

1. Select Payroll, then select Employees.
2. Select the employee, then select Paycheque list.
3. Select the paycheque and scroll down to the Employee taxes or Employer taxes section. You will see a separate line item for Second Canada Pension Plan.

Note: You will only see an amount for Second Canada Pension Plan after your employee has reached the earnings threshold outlined by the CRA.

Let me know if this info helps. I'll be a message away in case you need anything else. 

I have noticed the same thing on three of my clients.  Line 82 on the T4 Summary does not include the 2nd CPP Contributions from lines 16A and 27A.
