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: Before October 25

In Oregon, property taxes are calculated on the lesser of the Maximum Assessed Value or Real Market Value, with the result called the 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 $528,000 (Multnomah County's median), at Oregon's 100% assessment ratio your assessed value would be $528,000, resulting in approximately $5,069 in annual taxes at the county's effective rate of 0.96%.

The Appeal Process

Appeals are heard by the Board of Property Tax Appeals (BOPTA). Hearings are informal proceedings lasting 10 minutes where you present evidence to support your claimed property value. The board will issue a written decision, and you must continue paying your taxes during the appeal process.

Review your property tax statement carefully when it arrives before October 25. Contact the Multnomah County Assessor's office at 503-988-2225 via phone, email, or live chat to discuss your property value before filing an appeal, as appraisers can explain how your value was determined.

Gather evidence to support your appeal, including comparable sales data from properties sold near January 1, 2026 (the assessment date), independent appraisals, photographs showing property condition, repair estimates for any defects, and documentation of errors in property characteristics.

Obtain and complete the Property Values Appeals Board petition form by calling 503-988-2273, emailing pvab@multco.us, or visiting 501 SE Hawthorne Blvd, Suite 175. Submit a separate petition for each property account along with a $30 filing fee payable to Multnomah County.

File your appeal by mail to Property Values Appeals Board, PO Box 5007, Portland, OR 97208-5007, or in person at 501 SE Hawthorne Blvd, Suite 175, Portland, OR 97214. Your petition must be postmarked or delivered by December 31, 2026. Email and fax submissions are not accepted.

Attend your hearing scheduled between February 2027 and April 15, 2027. Hearings are held Monday through Thursday, 9am-2pm in 10-minute increments at the Multnomah Building (501 SE Hawthorne Blvd). You will receive a hearing notice 5-10 days in advance with your date and time.

Present your evidence at the hearing to the Property Values Appeals Board, focusing on the property's value as of January 1, 2026. The board will issue a written decision, and if successful, your assessed value and taxes will be reduced accordingly.

If you disagree with the Property Values Appeals Board decision, you may appeal to the Magistrate Division of the Oregon Tax Court within 30 days of the board's order being mailed. File a written complaint with the Oregon Tax Court at 1163 State St, Salem, OR 97301-2563.

What evidence do I need for a successful property tax appeal in Multnomah County?

To succeed in your Multnomah County property tax appeal, you need evidence demonstrating that your property's value as of January 1, 2026 was lower than the assessed value. The strongest evidence includes comparable sales data from similar properties that sold near the assessment date, showing lower prices than your assessed value. An independent appraisal conducted for the assessment date is highly persuasive. Photographs documenting property condition, defects, or needed repairs help support your case, along with contractor estimates or repair bids for any issues. Documentation of errors in property characteristics (square footage, lot size, features) recorded by the assessor can also reduce your value. Previous appraisals and expert opinions may be attached as supporting documentation.

How much can I save by appealing my property taxes in Multnomah County?

Successful property tax appeals in Multnomah County save homeowners an average of $1,747 per year, according to recent data. Your actual savings depend on how much your assessed value is reduced and Multnomah County's effective tax rate of 0.96%. For example, if you successfully reduce your assessed value by $50,000, you would save approximately $480 annually ($50,000 × 0.0096). With the median home value in Multnomah County at $528,000 and median annual taxes of $5,061, even a modest percentage reduction can result in hundreds of dollars in annual savings. However, not all value reductions result in tax savings due to Oregon's complex property tax calculation system involving Maximum Assessed Value caps.
