NEW YORK ( IRS.com) -- Up until tax year 2005, a taxpayer could file IRS Tax Form 4868 (Application for Automatic Extension of Time to File U.S. Individual Income Tax Return) and get a four-month automatic tax extension. An additional two-month tax extension could be obtained by completing Tax Form 2688.
Then the Internal Revenue Service (modified Tax Form 4868) to allow for an automatic six-month extension of the original April 15 filing deadline.
With a tax extension, income tax returns are due on or before Oct. 15 of the same year.Once you request a tax extension successfully, remember that you must file your tax return by the new extended deadline. If you miss the Oct. 15 due date, you will be subject to late fees, penalties and interest. It is also important to note that you will not be allowed to request further extensions. The IRS does not grant second or additional tax extensions, with the exception of the following special instances: Members of the U.S. military. Members of the Armed Forces serving in a combat zone or contingency operation are eligible for additional tax extensions of up to six months. The tax extension begins once their deployment ends. Refer to IRS Publication 3 (Armed Forces' Tax Guide) for information about requesting extensions and filing returns. Taxpayers living outside the U.S. Taxpayers who are U.S. citizens or residents living outside the United States (and Puerto Rico) may qualify for a second tax extension if they meet certain requirements. The taxpayer falling into this classification must send a letter by the first tax extension deadline (Oct. 15) to request an additional two-month tax extension for filing their federal income tax return.
