Follow the steps to complete the OR Publication OR-40-EXT online.

1. Click the ‘Get Form’ button to obtain the form and access it in the online editor.
2. Review the general information section, which outlines the due date extension and the circumstances under which you need to file for an Oregon extension.
3. Determine if you need an extension: Only request one if you owe Oregon tax, do not have a federal extension, and cannot file your return by the due date (May 17, 2021).
4. Select your extension payment method: If paying electronically, submit your payment before the return due date and select 'return payment' type. If paying by cash, check, or money order, complete Form OR-40-V and mark the 'original return' payment type.
5. Use the tax payment worksheet included with the form to calculate your extension payment, ensuring your payment is made by May 17, 2021, to avoid penalties and interest.
6. If applicable, mark the 'Extension filed' checkbox when filing your return to indicate that you have requested an Oregon or federal extension.
7. Keep the completed tax payment worksheet with your records; do not send it to the Oregon Department of Revenue.
8. Finalize the process to save your changes, download, print, or share the form as needed.
