Property Value Appeals

Contact the Assessor’s office at 503-655-8671 if you have questions regarding your property value. If you feel the market value shown on your tax statement is too high, we encourage you to file an appeal with the Board of Property Tax Appeals (BOPTA).

  • Appeals to the Board of Property Tax Appeals (BOPTA) may be filed after receipt of your tax bill but no later than Jan. 3, 2023.
  • Contact the Clackamas County Clerk’s office at 503-655-8662 for filing information, specific petition guidelines and to see a petition filing checklist for filing your appeal.
  • The Clerk’s phone number is 503-655-8662 and they are located at:
    Clackamas County Clerk, BOPTA
    1710 Red Soils Court, Suite 100 map

  • Appeals to the Board of Property Tax Appeals (BOPTA) must be for the current tax year only. The deadline to file an appeal is Jan. 3, 2023.

If you miss the above deadline or you disagree with a prior year's value you may file an appeal with the Magistrate Division of the Oregon Tax Court. Appeal forms may be obtained by calling Oregon Tax Court, Magistrate Division, 503-986-5650. Certain standards must be met to have appeals to the magistrate heard. Oregon Tax Court appeal forms are available in the Assessor's Office or you can download an Information Circular from the State about the appeals process.
