I just completed our FAFSA. What a beating. I had to separate out the w2 income between me and my husband. It’s combined on our irs form 1040 line 1 wages- since we file jointly. FAFSA wants each parents income reported separately. So I referred to our w2’s to figure out how much was his and how much was mine. Then I had to add my business income from schedule 1, line 3 (business income) to my w2 income to get my total income. And then reporting investments, savings, etc in the next section.
