IRS MeF federal and state program

We accept electronically filed calendar year, fiscal year, short year, and amended returns through the IRS' modernized e-file platform (MeF) for the following Business programs and returns: Corporation, Oregon Composite, Partnership, Transit Self-Employment, and Fiduciary. View our list of approved software vendors.

You can e-file the current tax year and two prior tax years with both Oregon and the IRS. Other years must be submitted on paper or 2-D barcode.

We accept returns e-filed using approved e-file software from any IRS-approved electronic return originator (ERO) or corporations who e-file directly with the IRS.

If your corporation is required to e-file your federal return, then your corporation is also required to e-file your Oregon return. In addition, if e-filing was required for the original return, then any amended returns for that year must also be e-filed. However, if that year is not open for e-file, you should paper file or file with a 2-D barcode.

Oregon corporate returns can be submitted electronically via the IRS as either a "linked submission" or an "unlinked submission." Both methods require that you include the electronic federal return, unless you're filing a Form OR-20-INS.

Federal return data

Oregon forms OR-20, OR-20-S, and OR-20-INC must include the federal return as submitted to the IRS, including any attachments.

Return acknowledgements

We send an acknowledgement of all returns received. Allow at least one business day to receive our acknowledgment before contacting us.


Returns are signed via a checkbox on the return. This serves the same purpose as physically signing your return.


You can make an electronic payment with your e-filed return, through Revenue Online, an electronic funds transfer, or by check. You can also mail check payments to us with an accompanying Form OR-20-V. Please don't mail a paper copy of your return if you e-filed but are paying by check.
