How Multnomah County Assesses Property

100%of market value

Assessed by: Multnomah County Division of Assessment, Recording & Taxation (DART)

Assessment cycle: annual

Notices typically mailed: Spring (typically mid-March to mid-April)

In Oregon, property taxes are calculated based on the lesser of the Real Market Value (RMV) or Maximum Assessed Value (MAV), which becomes your Assessed Value. Oregon uses a 100% assessment ratio, meaning properties are assessed at their full market value. For example, if your home's market value is $496,670 (the county median), at Oregon's 100% assessment ratio your assessed value would be $496,670, resulting in approximately $5,314 in annual taxes at the county's effective rate of 1.07%.

The Appeal Process

Appeals are heard by the Property Values Appeals Board (PVAB). Hearings are informal proceedings lasting 10 minutes where you present your evidence to appointed board members with property valuation experience. The Board makes decisions based on the evidence you present, focusing on property values for the current assessment year, not tax increases or prior year comparisons.

Contact the Assessor's Office at(503) 988-2225 or propertytax@https://multco.us before filing to discuss your property value and determine if an adjustment is warranted. Appraisers will help you understand how your value was determined.

Complete the Property Values Appeals Board Petition Form and submit it with a $30 filing fee (check payable to 'Multnomah County'). Appeals must be postmarked or delivered between October 25 and December 31 of the tax year being appealed.

Gather evidence supporting your appeal, including comparable sales from properties sold around January 1 of the tax year, photographs showing property condition, repair estimates, or independent appraisals. Focus your evidence on the Real Market Value as of January 1.

Attend your scheduled hearing at the Multnomah Building (501 SE Hawthorne Blvd). Hearings run from mid-February through April 15, lasting 10 minutes from 9 am-2 pm Monday-Thursday. You will receive notice of your hearing date 5-10 days in advance.

Present your evidence to the Property Values Appeals Board, which consists of appointed citizens with property valuation knowledge. The Board will mail you a written decision within 8-10 business days after your hearing.

If unsatisfied with the Board's decision, you may appeal to the Oregon Tax Court Magistrate Division by filing a written complaint within 30 days of the Board's order being mailed.

Further appeals can be made to the Oregon Tax Court Regular Division within 60 days of the magistrate's decision, and ultimately to the Oregon Supreme Court if necessary.
