Filing taxes before school deadline?

<p>I filled out the FAFSA form in January, but I put that my parents will file because they havn't yet. My question is do my parents have to file their taxes before the schools deadline for me to receive my financial aid package? On my online portal it says they have received my FAFSA, but it doesnt ask for anything else so I just want to make sure I'm not misssing something! Thanks!</p>
