In case you haven’t sent in your information to the IRS yet…now might be a good time to start. For people who aren’t filing for extensions, Tuesday is the deadline to send in your tax information. An extension will give you extra time to get your paperwork to the IRS, but it does not extend the time you have to pay any tax due. You will owe interest on any amount not paid by the deadline, plus you may owe penalties. All of the information on extensions is available at IRS.gov. E-filing is available through the website as well.
