Line 23400 less Line 23500 equals Line 23600. So, if your spouse didn't have any social benefit repayments, then Line 23400 is the same as Line 23600. 

You can see Line 23500 & Line 23600 on your spouse’s Detailed Tax Summary. Line 23400 is not on the Detailed Tax Summary; you will see it on your spouse’s T1.

Hello Isabella,

To find your spouse's net income- you will find this on their T1 general- on line 23400 and 23600.
