If you are going to claim a dependant credit or transfer from your daughter, her Net income (Line 23600) may be required to calculate the credit/transfer amount. If your daughter has no income, then just answer NO where it asks " Is [Name]'s income zero?".

Is T1 line 23600 line 14 Employment Income?  Or where do i find it?

My son lives at home is 17 and has made $19777.  Does he need ti file his return?
