<p>Prnceton want to know full income from work as would be reported in box 5 on W2 form for each parent independently. The problem is that they ask about income in 2014 and 2015 that will have to be estimated at this point. You should ask your parents for help.Usually this amount equals yearly salary minus yearly health insurance payments and minus other pre-tax benefits like FSA, Child care plan, etc. Do not subtract 401K contributions. Your parents will have to find their most recent paystubs and try to figure this out. To fully complete the form they will have to estimate AGI and other things on the form. This is not a trivial task, especially if they own a business/self-employed. You really need an adult to handle this and these estimations better be precise.</p>
