2023 Individual Income Tax Returns with 6-Month Extension Due
October 15
Individual income tax returns (Form 1040 and Form 1040NR originally due on April 15) with a Form 4868 filed or an electronic extension payment made, are due on this date.
Taxpayers out of country can request an additional discretionary 2-month extension of time to file their returns (to December 16) if they need more time. To request this, you must send the IRS a letter by October 15, explaining the reasons why you need the additional 2 months.
Returns e-filed or mailed and post-marked by USPS, official foreign postal services, or designated Private Delivery Services (PDS) on or before this date are deemed to have been filed on a timely basis.
