Property Value Appeals

Contact the Assessor’s office at 503-655-8671 if you have questions regarding your property value. After your discussion with the Assessor’s staff, 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 December 31, 2019.
  • 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 office phone number is 503-655-8662, and they are located at:
    Clackamas County Clerk, BOPTA
    1710 Red Soils Court, Suite 100 map
    Oregon City, OR 97045
  • Appeals to the Board of Property Tax Appeals (BOPTA) must be for the current tax year only. The deadline to file an appeal is December 31, 2019.

More appeal information from the Oregon Department of Revenue.

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. All appeal forms are available in the Assessor's Office or you can download an Information Circular from the State about the appeals process.
