Tax Day is the common term for the day on which tax returns (statements about income taxes) are due to the federal and state governments from U.S. citizens, resident aliens, and certain nonresident aliens.
More specifically, this is the last day on which tax returns can be mailed (as postmarked) to avoid penalties.
A lot of Americans have already finished their returns and submitted them, many folks will take time out today to fill theirs out and make the trip to the Post Office or hit send before midnight.
Tea Party activists plan rallies in cities across Washington Thursday as part of the national Tax Day political protests.
Organizers expected the biggest crowds at the noon rally at the Capitol steps in Olympia and a 5:30 p.m. rally in Westlake Park in Seattle.
Other Tea Party rallies are scheduled in Bellevue, Everett, Mount Vernon, Bellingham, Okanogan, Moses Lake, Richland, Prosser and Walla Walla.
