This is the EFC Formula. If you go to Page 13 it has the worksheet for Simplified Needs. Line 1-3 are asking for AGI and income from work. At the end of line 3 there is a footnote that if this number is 25K or less (I guess it’s 26K now) to stop filling out the form. You don’t go on to question 4 filling out untaxed income.
