Corporate Taxes
Corporate Taxes in Oregon
The corporate tax rate is 6.6 percent.
Oregon follows the federal entity classification regulations. If an entity is classified or taxed as a corporation for federal income tax purposes, it will be treated as a corporation for Oregon tax purposes.
Oregon corporation tax law, in general, is tied to the Internal Revenue Code (IRC) as amended and in effect on December 31, 2004. Effective January 1, 2005, an automatic connection to future changes to the federal definition of taxable income
applies in Oregon, unless a specific Oregon law provides for different treatment. Oregon's definition of taxable income for corporations begins with federal taxable income, with modifications required under Oregon tax law. See Chapters 317 and 318 of the
Oregon Revised Statutes and the
Oregon Administrative Rules.
