The things that show up in my email!
Income taxes are normally due on April 15th unless that date falls on a Saturday or Sunday, in which case they are due on Monday the 16th or 17th.
However, I have been told that rule has recently been changed for 2008, as well as the next four years. The new rule states tax payments are no longer due until you are nominated to a cabinet position.
