Property Tax Appeal · Multnomah County, OR
Appeal your property taxes
in Multnomah County, OR.
Home to Portland, Multnomah County homeowners appeal through Oregon’s system: the county assessor sets the value, and the Property Value Appeals Board (formerly BOPTA) hears the case. Boards act on evidence of market value as of the assessment date — a licensed, USPAP-compliant appraisal is that evidence. Start with the $5 check to see what you’d save.
December 31 — petitions to your county’s Property Value Appeals Board are due by year’s end, following the tax statements that arrive in October. This one is statewide. Your assessment notice states the exact date — and the appraiser prepares your report and filing guidance for Multnomah County’s procedure.
Before petitioning, compare the RMV and MAV lines on your statement: if RMV sits far above MAV, even a big RMV win may change nothing. New construction, newly created accounts, and cooled markets are where Oregon appeals actually pay.

December 31 — petitions to your county’s Property Value Appeals Board are due by year’s end, following the tax statements that arrive in October. This one is statewide. Your assessment notice states the exact date for Multnomah County.
Oregon’s Measure 50 gives every property two values: real market value (RMV), the assessor’s estimate of what it would sell for, and maximum assessed value (MAV), a capped figure that grows no more than 3% a year — and you’re taxed on the lower of the two. Tax statements arrive in October, and appeals go to your county’s Property Value Appeals Board (the renamed Board of Property Tax Appeals) by December 31. The catch that surprises Oregonians: cutting RMV only reduces taxes if it falls below your MAV or triggers compression, because MAV is usually the number you’re taxed on. When the market has genuinely dropped under your MAV — or a new build or remodel set values too high — a licensed appraisal establishing RMV as of the January 1 assessment date is the evidence the board is built to weigh.
Comparable sales as of the assessment date, adjusted for the differences between those homes and yours — the substance of a licensed appraisal. Property Value Appeals Board (formerly BOPTA) panels see hundreds of cases; a signed, USPAP-compliant report is the document they can act on.
We’re not an AVM, a computer model, or a real-estate agent estimate. Every report is prepared under the Uniform Standards of Professional Appraisal Practice (USPAP) and signed by a licensed appraiser in your state — the same qualification required for mortgage appraisals.
