Appeal your property taxes in Multnomah County, OR.

How it works
How to appeal your property taxes in Multnomah County.
- Step 1
Check your savings
Enter your address and pay $5. We check your Multnomah County assessment against recent nearby sales.
- Step 2
Order the appraisal
A desktop appraisal valued as of your assessment date, with the $5 credited. Complex homes get one exact quote.
- Step 3
Show us your home
Walk through on your phone so the appraiser sees its condition. A desktop appraisal needs no visit.
- Step 4
File your appeal
A state-licensed OR appraiser signs it, with a cover letter and filing steps. You file by your deadline, and the Property Value Appeals Board (formerly BOPTA) hears your case.
The evidence
Boards act on value, not frustration.
However Oregon labels the process, the case underneath is the same: show what your home was actually worth on the assessment date. A licensed, USPAP-compliant appraisal, with comparable sales, documented adjustments and a signed opinion of value, is that showing.

The process
How Oregon handles appeals.
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.
Worth knowing in Oregon
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.

What evidence should I bring?
Comparable sales as of the assessment date, adjusted for the differences between those homes and yours — potential supporting evidence. Check the reviewing authority’s rules for admissibility, valuation date, forms and filing. An appraisal does not guarantee a reduction.
