Is there any benefit to filing the FAFSA early as opposed to just before a deadline?
The earlier the better. If there is any problem with the application, you will have extra time to deal with correcting the problem. In fact, you can avoid errors by filing on line. FAFSA on the Web has edits built in to catch errors before processing. However, you cannot file the FAFSA until January 1 of the year you are applying for aid.
