The Free Application for Federal Student Aid (FAFSA) is currently available online at https://fafsa.ed.gov
Make sure you have your FSA ID to fill out the FAFSA. Visit https://fsaid.ed.gov for more information and details.
(The FSA ID has replaced the PIN.)
For the FSA ID, the parent and student need to use two different emails. Both must have a personal email to register for the ID. It is best to use a home email, rather than a school or work email since you need to be able to access it for the next few years. When you request your FSA ID, it may take 1-3 days to receive the information.
For more information, visit the Federal Student Aid website at https://studentaid.ed.gov/sa/about/announcements/fafsa-changes and http://www.fafsahelpoh.org/
