Six months If you file for an extension on your individual tax return, the IRS will give you six more months to complete the return. The IRS changed the extensions in 2006. There is now only the option for 6-month extensions (it used to be that you would file one extension, and could then file a second one for a total of 6 months).
Most individuals and families are required to file by the federal due date, which is on or around April 15th each year. An automatic extension for up to six months can be obtained by completing a form 4868 with the Internal Revenue Service, but the extension must be filed by or before the federal due date. Once filled, a 1040 return can be completed anytime within the six month period.
