Property Tax Appeals · Oregon
Appeal your property taxes
in Oregon.
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.
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.
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.
The evidence
Boards act on value,
not frustration.
However Oregon labels the process, the case underneath is identical: show what your home was actually worth on the assessment date. A licensed, USPAP-compliant appraisal — comparable sales, documented adjustments, a signed opinion of value — is that showing. Start with the $5 check to see if the numbers are on your side before you spend real money.
- Valued as of your assessment date — not today
- Comparable sales with adjustments and citations
- Signed by a state-licensed OR appraiser
- Phone walkthrough — no stranger in your home
- Delivered in 48–72 hours, rush available

Oregon questions
December 31, statewide, to your county’s Property Value Appeals Board. Tax statements mail in October, which leaves a comfortable window to commission evidence.
Only if the corrected RMV drops below your maximum assessed value or triggers compression — Measure 50 taxes you on the lesser of the two. Compare both numbers on your statement first; that check is the whole go/no-go decision.
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.
