Watch this video about paying taxes on HowStuffWorks. Procrastinators and the rest of the country have an extra day to prepare and file federal income taxes because the IRS recently announced that the filing deadline for 2006 tax returns will be April 17, 2007. That gives millions of taxpayers more time to take advantage e-filing their federal tax returns, and good thing since more than 73 million Americans chose IRS e-file in 2006. See how taxes work in this video from Medialink.
