When are U.S. Personal Tax Returns due?

US personal tax returns are due on April 15 of the following taxation year. However, if you live and work outside the US on a normal basis, the deadline is automatically extended to June 15. Furthermore, any taxpayer may request additional time to file by filing this form to the IRS by their due date. With this form, the deadline is extended to October 15. Regardless of whether you qualify for the automatic 2 months extension or the extension until October 15, if you have any tax balances owing, the interest will accrue beginning April 15.
