Understanding IRS Form 4868 Deadline: Everything You Need to Know

When tax season approaches, many individuals and businesses find it challenging to meet the April tax filing deadline. Thankfully, the IRS provides relief through Form 4868, the Application for Automatic Extension of Time to File U.S. Individual Income Tax Return.

Taxpayers need to understand the importance of filing IRS Form 4868 when required. Unlike other tax forms, Form 4868 does not have a separate due date; its deadline aligns with the original due date of the taxpayer’s Form 1040 tax return.

April 15th

If you’re a calendar year filer and your tax year ends on December 31st, the due date for filing your federal individual income tax return is generally April 15th of each year.

Deadline if abroad

June 16th

However, for US citizens living overseas, this deadline is automatically extended to June 16th. All individuals who live oversee can request an extension for an additional 4 months to obtain a total of 6 months of extension.

Note: If the mentioned due date or deadline falls on a weekend or a United States government holiday, taxpayers can e-file on the next business day.

How long is the extension?

Filing this form gives you until October 15th to file a return.

If the deadline falls on a Saturday, Sunday, or legal holiday, the due date is delayed until the next business day. Your return is considered filed on time if the envelope is properly addressed, postmarked, and deposited in the mail by the due date. To get the extension, you must estimate your tax liability on this form and should also pay any amount due.
