If you have a Registered Domestic Partnership (RDP), Oregon requires you to determine your tax liability by completing the federal return "as if" you were filing using the Married Filing Joint or Married Filing Separate status.
The state may require you to mail copies of the federal return or supporting documents after you have e-filed.
