One of the big stories during the opening days of tax season was the fact that taxpayers would have until April 18 — instead of the usual April 15 — to file their taxes.

The extension is due to the fact that Emancipation Day, a holiday in the District of Columbia, falls on Friday, April 15. Since D.C. holidays have the same impact on tax deadlines as federal holidays do, “all taxpayers will have three extra days to file this year,” the IRS says.

All taxpayers, that is, except for those in Virginia. Here's what the Virginia Department of Taxation had to say in a recent listserv post:

“Several tax preparers have asked if Virginia’s due date for calendar-year corporate income tax and pass-through entity tax returns is going to be moved to April 18 this year because the IRS moved (its) filing deadline to April 18 in honor of Emancipation Day in Washington, D.C.

“Our due date for calendar-year filers will remain April 15, 2011. We do not change the due date of returns because of holidays in other cities, states or countries. Virginia law directs us to extend the due date only when the due date falls on a Saturday, Sunday or legal holiday, and Emancipation Day is not among the Virginia legal holidays.”

So there you have it. Tax Day 2011 is April 18 … except Virginia.
