You actually did find it; hopefully your parents properly filled out their return. While you should fill out the FASFA with your Dad, because the Fasfa is filled out on-line, and you need to have your parent's return (or the prior year's to estimate), if you parent's had "zero" on line 55, look at line the line above it and see if there were any credits against tax. It is very possible to have zero tax due if there are enough credits. Also look at line 44 and 45 and see if your parents had any tax before credits. This is not the number you use for FASFA, but may tell you if they owed tax or not (before credits). These days, many self-employed parents may not be earning like they used to, and may be relying on savings and other resources to make it each year.
