The Board of Property Tax Appeals (BoPTA) consists of three non office-holding residents of the county and is responsible for hearing taxpayer appeals for reduction of the real market or assessed value of property. BoPTA members are appointed by the Benton County Commissioners on or before October 15^th each year and the term ends on June 30^th. 

Please complete an Online Application, for the Board of Property Tax Appeals, if you would like to be considered by the County Commissioners for appointment to this board.

In Oregon, property taxes are assessed against real property, machinery and equipment, manufactured structures, business personal property and floating property. Oregon has an ad valorem tax system – the property taxes you pay are based on the value the County Assessor establishes for your property. Property values may be appealed to BoPTA as prescribed by Oregon law beginning each year the day after tax statements are mailed, usually sometime between the middle to end of October, through the end of the year December 31^st.

If you are not in agreement with the value placed on your property as shown on the tax statement, you are encouraged to contact the Assessor to request a review of property values prior to filing an appeal.  The Benton County Assessors office can be reached at 541-766-6855 and is located at 4500 SW Research Way, Corvallis, OR 97333.  To help answer common questions, the Benton County Assessor provides the following FAQ section on their website.  An appeal before BoPTA would be the next step if an agreeable solution is not reached.  For additional information, take a look at the BoPTA Appeal Process Reference Guide at the bottom of this web page.

The State Department of Revenue or DOR provides instructions and forms on their website that may be printed out, completed and filed with the appropriate County Clerk by the December 31^st deadline or next business if the deadline falls on a holiday or the weekend. Please, review the instructions included with the petition form to complete the petition correctly.  Petitioners are encouraged to include as much information possible in support of their case, as the burden of proof falls on the Petitioner. The appeal process is not to challenge the taxes but to appeal the current year real market, maximum assessed, specially assessed or assessed value of the property. For example, if the request is for the board to reduce the market value of the property, evidence presented should prove what the property’s value is, not just the amount of taxes being paid.

Possible documentation used to support the Petitioner's value of the property could include:

• Recent sale of the property
• Fee appraisal of the property dated close to January 1^st of the assessment year which reflects the property’s value
• Sales information about comparable properties
• Proof that the property had been listed for sale on the open market for reasonable period of time at a price below the real market value listed on the tax roll
• Cost to repair the property (i.e., written estimates, invoices, etc.)

It is advisable to submit supportive documentation with the filed petition, however, if there is no evidence submitted with the completed petition, the Petitioner is encouraged to send/bring in 1 copy of complete evidence/materials up to 2 days prior of the scheduled hearing, or bring in 5 copies of complete evidence to hand out at the hearing. All materials should not exceed legal size (8½” x 14”) and evidence is not returned to the Petitioner.

To start the appeal process in Benton County, petitions are received ONLY in the County Clerk’s Office beginning after tax statements have been mailed out in mid-October through the deadline, 5:00pm on December 31^st or next business if the deadline falls on a holiday or the weekend.  Petitions can be returned by the following methods:
