Oregon Extension For State Taxes

For the 2025 Oregon individual income tax return, Oregon allows taxpayers to file an extension if they have a federal extension or request an Oregon-specific extension. The due date for filing the 2025 Oregon return is April 15, 2026, and if you file an extension, the new due date is October 15, 2026. Oregon honors all federal automatic six-month extensions (federal Form 4868) as valid extensions for Oregon purposes.

Extension Filing Requirements

• Federal Extension Accepted: If you have a federal extension, Oregon will accept it without requiring a separate Oregon extension request.

• Requesting an Oregon Extension: If you

  • Do not have a federal extension
  • Need more time to file your Oregon return AND
  • owe tax,

  You may request an automatic extension using Publication OR-40-EXT.

  The Oregon filing extension request is based upon your extension payment method. NOTE: If you Do Not OWE taxes, and extension is not needed

• Payment Deadline: Regardless of whether you file an extension, any tax owed must be paid by April 15, 2026, to avoid penalties and interest. The extension only extends the filing deadline, not the payment deadline.
