ITG FAQ #13 Answer-When must I file my individual income tax return?
April 15th each year is the due date for filing your Federal individual income tax return. Your return is considered filed timely if the envelope is properly addressed and postmarked no later than April 15th. If the due date falls on a Saturday, Sunday, or legal holiday, the due date is delayed until the next business day.
If you cannot file by the due date of your return, then you can request an extension of time to file. However, an extension of time to file is not an extension of time to pay. You will owe interest on any past-due tax and you may be subject to a late-payment penalty if payment is not made timely. To receive an automatic 6-month extension of time to file your return, you can file Form 4868 (Application for Automatic Extension of Time to File) by the due date of your return. For more information, refer to the Form 4868 Instructions.
