If you can get that POA…you need the 2016 tax return for the 2018-2019 FAFSA, and then any information about assets…bank a counts, etc. it would be helpful to have th 2016 W2 forms as those would also have the a,nots of contributions to tax deferred retirement accounts on them.
But you need to know who has to complete the fafsa. Student only…or student and parent (or POA for parent).
I’m not sure how POA works in terms of getting a parent FSA ID number if the parent is needed on the forms. That might be a good question when you visit the financial aid office…or a call to,the fafsa helpline.
