Tax season will last a little longer this year thanks to a holiday being celebrated in Washington, DC.  The deadline for filing your 2010 tax return will be Monday, April 18, 2011.  The due date is normally April 15, but this year, the 15th falls on a holiday called “Emancipation Day” that is celebrated by Washington, DC.  Even though the holiday is only celebrated in Washington, DC, we all benefit from it by getting 3 extra days to file our tax returns.
