Follow the steps to fill out the OR-40-EXT form online:

1. Click the ‘Get Form’ button to obtain the OR-40-EXT form and open it for editing.
2. Review the general information provided in the document to determine if you need an extension. Remember, Oregon honors federal extensions, so you can skip this if you already have a federal extension.
3. If you owe Oregon taxes and do not have a federal extension, complete the extension request. Indicate your payment method, either electronic or by check.
4. If using electronic payments, ensure you select the ‘Return payment’ type when submitting your payment prior to the due date.
5. If you're paying by check, complete Form OR-40-V, marking the ‘Original return’ payment type box, and mail it along with your check by the due date.
6. Make sure to mark the ‘Extension filed’ checkbox on your Oregon tax return to indicate that you have requested an extension.
7. If you are a fiscal-year taxpayer, ensure your extension payment follows the regular due date of your return.
8. Remember, an extension to file is not an extension to pay. Make sure to pay the estimated tax by the due date to avoid penalties.
9. After completing all fields and sections, review your entries for accuracy. Save any changes you made.
10. Finally, download, print, or share the completed form as necessary.
