Welcome to the Assessor's Office

Polk County Courthouse

Welcome to the Polk County Assessor’s website. We are committed to providing convenient access to information 24 hours a day, 7 days a week.

The goal of the Assessor’s Office is to ensure fairness and equity of property assessments, equitable interpretation of and compliance with statutory laws regarding property assessment, and that all recorded legal documents are processed in a timely manner and reflect accurate records of ownership.

The Assessor's Office is comprised of three areas: records, valuation and cartography. Together they are responsible for assessing all properties in Polk County which includes residential and rural properties, commercial, industrial, manufactured structures, and business personal property. We maintain records on approximately 36,436 property tax accounts.

Our office also manages special programs such as veterans' exemptions, senior deferrals, special assessments, and enterprise zone exemptions. Maps and information on property locations, descriptions and ownership are also maintained.

Oregon’s property tax system has changed during the past 15 years. This has become more complex since the passage of Measure 5 and 50, which now extend, impose, and set a tax base on each property.

Under Oregon Law, you have the right to appeal the Real Market Value (RMV) of your property to the Assessor or to the Board of Property Tax Appeals (BOPTA).  BOPTA is limited to the current tax year values.  In some cases you may be able to appeal the Maximum Assessed Value (MAV), Specially Assessed Value (SAV) and Assessed Value (AV) of your property.
