Hello Tax Professionals,

For tax year 2012 and forward, e-filed Oregon corporation tax returns are signed using a check box on the return. This is a taxpayer (authorized officer) signature. The tax software requires that the box be checked before the return can be successfully e-filed. If your corporate client provides you with a properly completed federal Form 8879-C, IRS e-file Signature Authorization for Form 1120, it is okay for you to check the box on behalf of your client when you prepare/submit the Oregon corporation tax return.
