What if You Can’t File on Time?

You can get an automatic 6-month extension if, no later than the date your return is due, you file Form 4868. If you want to apply for an extension electronically, see Form 4868 for details.

An automatic 6-month extension to file doesn’t extend the time to pay your tax. If you don’t pay your tax by the original due date of your return, you will owe interest on the unpaid tax and may owe penalties. See Form 4868.

If you are a U.S. citizen or resident alien, you may qualify for an automatic extension of time to file without filing Form 4868. You qualify if, on the due date of your return, you meet one of the following conditions.

You live outside the United States and Puerto Rico and your main place of business or post of duty is outside the United States and Puerto Rico.

You are in military or naval service on duty outside the United States and Puerto Rico.

This extension gives you an extra 2 months to file and pay the tax, but interest will be charged from the original due date of the return on any unpaid tax. You must include a statement showing that you meet the requirements. If you are still unable to file your return by the end of the 2-month period, you can get an additional 4 months if, no later than June 15, 2026, you file Form 4868. This 4-month extension of time to file doesn’t extend the time to pay your tax. See Form 4868.
