You annually must complete a Free Application for Federal Student Aid (FAFSA). Go to FAFSA to complete the online FAFSA. Sign your FAFSA electronically using a Federal Student Aid ID (FSA-ID). Request an FSA-ID at the top of the FAFSA webpage. A parent must also obtain an FSA-ID in order to "sign" the FAFSA. The FAFSA is used to apply for all types of aid from federal, state, college and private sources. The FAFSA is FREE. Income and tax information from 2016 is used on the 2018-19 FAFSA.
