This is the priority filing deadline for UCSB financial aid and for Cal Grants. Students who file a 2009-2010 FAFSA after this deadline will only be considered for federal Pell Grants and student loans. Students who file the paper version of the FAFSA should obtain a "certificate of mailing" from the U.S. Post Office as proof that they filed by the priority filing deadline. Even if you have not filed your 2008 federal tax return by the FAFSA priority deadline, you can still supply estimated information on the 2009-2010 FAFSA in order to file by the deadline.
