Corporate returns (Form OR-20 – Oregon Corporation Excise Tax Return) – current year and two prior years.

S Corporation returns (Form OR-20S – Oregon S Corporation Tax Return) – current year and two prior years.

Partnership returns (Form OR-65 – Oregon Partnership Return of Income – current year and two prior years.

Fiduciary returns (Form OR-41 – Oregon Fiduciary Income Tax Return) – current year and two prior years.


Business Return General Information

Due Dates for Oregon Business Returns

Corporations – Returns are due by the 15th day of the month following the due date of the federal corporation return. For calendar year filers, this means the due date is April 15.

S-Corporations – Returns are due by the 15th day of the month following the due date of the federal corporation return. For calendar year filers, this means the due date is April 15.

Partnerships – March 15 – Returns are due by the 15th day of the third month following the close of the partnership’s tax year if it is on a fiscal year.

Fiduciary – April 15 – Returns are due by the 15th day of the fourth month following the close of the tax year if the entity is on a fiscal year.

Business Extensions

C Corporation and S Corporation – Corporations that have obtained a federal extension by filing Form 7004 with the IRS are also extended six months to file their Oregon return, and the OR-20 can be e-filed on extension.

However, a corporation that is seeking to extend filing only the Oregon tax return must complete the Federal Form 7004 by hand, write “For Oregon Only” at the top of the form, and include the form with the Oregon return when it is filed. Since the state of Oregon does not support PDF attachments to e-filed returns, the Oregon return cannot be e-filed.

Irrespective of whether the Federal return has been filed on extension or not, to indicate in Keystone Tax Solutions Pro that the Oregon return has an extension attached, from the OR-20 main menu select Heading Information > An Extension is attached.

Any extension of time to file the Oregon return does not extend the time to pay any tax due by the original due date of the return. Payment can be made online or by mail with Form OR-20-V by the original due date of the return.

Partnership – Partnerships that have obtained a federal extension by filing Form 7004 with the IRS are extended five months to file their Oregon return. To file an Oregon only extension, use voucher Form OR-65-V. Check the extension box on the voucher and send it in by the original due date of the return, with payment if necessary.

An extension to file does not mean more time to pay. To pay the $150 minimum tax, check the extension box on voucher Form OR-65-V and send the voucher and payment by the due date. The maximum extended due date is September 15 for calendar tax year partnerships.

Fiduciary –  Estates and trusts that have obtained a federal extension by filing Form 7004 with the Internal Revenue Service are also extended five and a half months to file their Oregon return. To indicate the return is being filed on extension in the program, from the main menu of the OR-41 select Heading Information > Is an extension attached.

To file an Oregon only extension, use voucher Form OR-41-V. Check the extension box on the voucher and send it in by the original due date of the return, with payment if necessary.

An extension to file does not mean more time to pay. Full payment is due on the due date of the return. Penalty accrues on the tax balance unpaid by the return due date, but for a return on extension the penalty can be avoided if the entity:

  • Pays at least 90% of the tax due by the original due date of the return; and
  • Pays the balance of tax and interest when the return is filed within the extension period; and
  • Pays any interest due either when the return is filed or within 30 days of DOR billing.

Amended Business Returns

C Corporation and S Corporation – To indicate that a return is amended in the program, from the main menu of the Form OR-20 select Heading Information > This is an amended return.

Partnership – To indicate that a return is amended in the program, from the main menu of the Form OR-65 select Heading Information > Amended return.
