Up until tax year 2005, a taxpayer could file Tax Form 4868 and obtain a four-month automatic tax extension. An additional 2 month tax extension could be obtained by completing Tax Form 2688. However, effective with tax year 2005, the Internal Revenue Service modified Tax Form 4868, allowing an automatic six-month extension from the April 15th deadline. With a tax extension, income tax returns are due on or before October 15th. There are no second tax extensions with the exception of the following instances:
1. Members of the Armed Forces serving in a combat zone or contingency operation are eligible for additional tax extensions of time up to six months. The tax extension begins once the deployment ends. Refer to Internal Revenue Service Publication 3 for details relative to information about this tax extension request.
2. Taxpayers who are U.S. Citizens or residents who live outside the United States and Puerto Rico may qualify for a second tax extension. The taxpayer falling into this classification must send a letter by the tax extension due date, October 15th, to obtain up to a two-month additional tax extension for filing their federal income tax return.
Additional types of tax extensions include the following tax forms (all which can be found online):
