The FAFSA (Free Application for Federal Student Aid) should be completed in January of your senior year.  Parents must input the previous year's tax return information in order to complete the application.  This will help the college determine if you get financial aid and how much will be awarded to you.

Make sure to go to FAFSA.gov.  You should never pay any fee to apply for financial aid.  Here is the website http://fafsa.gov.
