A calendar marked with a red circle around the tax filing deadline date, surrounded by tax forms and a calculator.

Standard Filing Deadline

For most taxpayers, April 15th is the standard deadline to file federal income tax returns. If this date falls on a weekend or holiday, the deadline is typically extended to the next business day. For 2024, the filing deadline is Monday, April 15th, 2024.

Extensions and Special Circumstances

Automatic Extension (Form 4868)

If you need more time to file your taxes, you can request an automatic 6-month extension by filing Form 4868. This extends your filing deadline to October 15th. However, it's important to understand:

  • The extension applies only to filing your return
  • It does not extend the deadline for paying taxes owed
  • You must estimate and pay any taxes due by the original deadline

Special Circumstances

Natural Disasters

The IRS occasionally provides extensions for taxpayers affected by natural disasters. Check the IRS disaster relief page for current announcements.

Military Personnel

Active duty military personnel serving in a combat zone typically receive:

  • 180 days after leaving the combat zone to file returns
  • Additional time for other tax-related actions

Different business structures have varying filing deadlines:
