About the tax
On May 16, 2019 House Bill 3427 became law.
The legislation accomplished the following:
- Established a "Fund for Student Success" that is separate and distinct from the state's general fund.
- Adopted 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 is transferred to the Fund for Student Success and is used for education spending
The CAT is imposed on businesses for the privilege of doing business in Oregon. It is measured on a business's commercial activity, which is the total amount a business realizes from transactions and activity in Oregon. Certain items are excluded from the definition of commercial activity and, therefore, will not be subject to the CAT. In addition, Oregon's CAT allows a 35 percent subtraction for certain business expenses.
The CAT is applied to taxable Oregon commercial activity more than $1 million. The tax is computed as $250 plus 0.57 percent of taxable Oregon commercial activity of more than $1 million. Only taxpayers with more than $1 million of taxable Oregon commercial activity will have a payment obligation.
