Resources, agencies and counties · resources
What this source covers
Identify the specific tax notice and use the matching objection, conference or Tax Court appeal route.
How to use it
Who this route is for: Taxpayers disputing an Oregon DOR personal-income or corporation-tax action covered by the notice.
Prepare: Complete DOR notice and date; Tax year and taxpayer identifier; Explanation and new supporting information; Representative details if applicable; Revenue Online or postal submission proof
How to proceed:
1. Identify the exact notice type and review the appeal table and appeal instructions in the letter.
2. Prepare the required contact, tax-year, identification and explanation information.
3. For an available DOR objection or conference, submit through Revenue Online or the published address.
4. If the notice requires a Tax Court appeal, use that court’s forms and fee instructions instead.
5. Keep proof and update contact details during the process.
Timing and notices: Periods vary by notice and remedy. The agency’s live appeal table and your letter control; interest continues on unpaid taxes during an appeal.

Limits and questions to verify
A payment plan or penalty-waiver request is not necessarily an appeal. Some penalty-waiver determinations are generally not appealable to the Magistrate Division.
