A student can't simply choose to file as an independent on the FAFSA, the application that most schools use to determine financial aid awards. For the most part, the FAFSA relies on parental information unless the student is applying for graduate school.
You may not need to provide any information about your parents on your application form for the free federal study grant (FAFSA).
If you answered NO to ALL of these questions, you may be considered a dependent student and may be required to provide your parents' financial information when completing the FAFSA form.
