The State of Oregon will automatically grant you a 6-month tax extension if you were approved for a federal tax extension and have no tax balance due. However, you will need to submit Oregon Form 40-EXT (PDF) if you need to make a state tax payment or if you were not approved for a federal extension. If you do not need to make a tax payment and have received an approval notification from FileLater, there’s nothing more to do. Be sure to attach a copy of your extension form when you file your state tax return.

Filing for an Oregon tax extension will not provide you with additional time to pay any tax balance due, which must be paid by the original filing deadline, or interest and other payment penalties may apply.

For additional information, please visit the State of Oregon Department of Revenue website.
