Two T4's from different provinces. CPP is maxed out on ON, and I only have CPP2 on AB T4 - Turbotax gives an error

I have two T4's - one from Ontario and one from Alberta.

I am assuming that I maxed out on CPP (Box 16) as I have CPP2 (Box 16A) to enter for Ontario, and Alberta, but no CPP for Alberta.

Turbotax will not allow me to save the Alberta T4 without a value for the Alberta CPP

This is a common headache for multi-province filers this year. Because the "CPP2" (Box 16A) is a relatively new addition to the T4, many tax software platforms have rigid validation rules that expect a standard CPP contribution (Box 16) to exist before they'll accept a second-tier one.

Since you reached the maximum CPP limit with your first employer, your Alberta employer correctly left Box 16 empty but deducted the additional 4% for CPP2 (Box 16A).

Here's how to deal with this in TurboTax so you can save and move forward:

TurboTax often interprets a blank field as "missing data," but it treats 0.00 as a valid entry.

Go to the Alberta T4 entry screen.

In Box 16, manually type 0.00.

Ensure Box 16A contains the amount shown on your slip.

Check Box 26 (Pensionable Earnings). If it is blank on your slip, enter the amount from Box 14 (up to the annual maximum).

If the above workaround does not work, please contact our product support so that they can assist you with screensharing and navigation.
