About the ta​x

On May 16, 2019, Governor Kate Brown signed House Bill 3427 into law.

The legislation accomplishes the following:

  • Establishes a "Fund for Student Success" that is separate and distinct from the state's general fund.
  • Adopts a new Corporate Activity Tax (CAT) imposed on all types of business entities.

The CAT is in addition to the state's current corporate income tax. Revenue from the CAT will be transferred to the Fund for Student Success and will be used for education spending. 

The Oregon Legislature has concluded. The department will begin rule writing this summer/fall for the new CAT program. We will involve stakeholders during the process.

The Oregon Department of Revenue will host a series of town hall meetings across the state to seek input from business taxpayers and tax preparers about the administrative rules for Oregon’s new Corporate Activity Tax.

Traveling across Oregon, rule writers will sit down to hear the concerns, questions, and suggestions of those affected by the rules.

​The meeting schedule for business taxpayers and tax preparers is now available. For those who are unable to attend the in-state meetings, DOR is planning a series of conference calls. Those meetings will be scheduled once the in-state tour is complete.
