Nov. 15 is a significant deadline for not-for-profit organizations, including those with fiscal years ended June 30. The upcoming Nov. 15 is the deadline for fiscal year-end nonprofits to either file their 2009 tax year returns or an application for extension of time to file. It is also the final filing deadline for nonprofits with calendar year-ends who have previously applied for extensions.
