Property value appeals will be accepted once tax statements are distributed in late October 2023 and the deadline is Jan. 2, 2024. Forms can be obtained on the forms page. Please use the forms on this webpage and not the generic State webpage as our forms contain additional information when filing in Clackamas County. The Clackamas County forms also contain filing deadline information, the appeal timelines, instructions on how to file, frequently asked questions, and contact information if you require assistance in filing.
It is important to read the instructions provided with filling out your property petition. To be clear, these are appeals of property value, not property taxes. If BOPTA reduces RMV but it remains higher than MAV, AV won’t change. If the AV does not change, typically the amount of taxes owed on your tax statement will not change either as explained below.
Assessed Value (AV) is the value used to calculate your taxes. AV is the lesser of Real Market Value (RMV) or Maximum Assessed Value (MAV). Real Market Value (RMV) is the value the assessor has estimated your property would sell for on the open market as of the assessment date. Maximum Assessed Value (MAV) is the greater of 103 percent of the prior years assessed value or 100 percent of the prior years MAV. MAV be increased above 3 percent of the prior years assessed value if certain changes defined as exceptions are made to your property (i.e. remodels, additions, etc).
MAV doesn’t appear on tax statements but can be found by typing in a property tax account number or address on the Assessment and Taxation office property detail webpage. The assessment date for property is Jan. 1 preceding the mailing of the tax statements in October.
Assessed Value (AV) is established by a simple comparison between RMV and MAV and is equal to whichever one is less. It can only change as the result of changes to RMV or MAV. If BOPTA reduces RMV but it remains higher than MAV, AV won’t change.
