Taxpayer Authorization Forms

On November 1, 2024, the Oregon Department of Revenue (DOR) launched two new authorization forms and instructions, OR-AUTH-REP (Authorization to Represent) and OR-AUTH-INFO (Authorization to Receive Tax Information) to replace the Tax Information and Power of Attorney for Representation Form.

DOR staff received feedback from customers and tax professionals, and we simplified our process and made it more clear. Along with each form is a set of instructions.

If you have questions, contact us at 503-378-4988 or 800-356-4222 or questions.dor@dor.oregon.gov.

Submit your completed form through your Revenue Online account, or by email to questions.dor@dor.oregon.gov, or by mail to Oregon Department of Revenue, 955 Center St. NE, Salem, OR 97301-2555
