Oregon Commercial Property Tax Appeals

Oregon gives every property two values and taxes the lesser — which is why many appeals here save nothing, and the right ones save plenty. How Measure 50 and compression actually work, and every deadline through the Oregon Tax Court.

Why Oregon Is Different

Two Values, One Bill

Since Measure 50, every Oregon property carries two values: Real Market Value (RMV) — the assessor's opinion of what it would sell for — and Maximum Assessed Value (MAV), a capped figure that grows at most 3% a year. You are taxed on the lesser of the two.

That lesser-of rule produces Oregon's signature disappointment: an RMV reduction that doesn't reach below MAV changes nothing. Owners win a six-figure value cut at the board, then open a tax bill that didn't move a dollar — because the bill was riding on MAV all along.

There are two ways an Oregon appeal pays. Either the RMV cut lands below MAV, so assessed value falls with it — or the property is in Measure 5 compression, where the constitutional caps ($10 general government + $5 education per $1,000 of RMV) bind and every dollar of RMV reduction lowers the bill at roughly 1.5%. And compression is not an edge case: in high-rate jurisdictions — Multnomah County, Oregon's largest, chief among them — consolidated rates run well past the caps, so commercial RMV reductions routinely pay even while RMV sits above MAV. Screening which zone your property occupies — before filing — is the difference between an appeal and an exercise. It's the first thing SVA models on every Oregon engagement.

The Appeal Calendar

Every Date That Matters

Oregon's window opens when the tax statement arrives in the fall and slams shut at year end — an off-cycle calendar that catches owners focused on spring deadlines elsewhere.

Real Propertyland & buildings
  1. January 1
    Assessment date
    Values are set as of January 1 for the tax year beginning the following July 1. All market evidence anchors here.
  2. By October 25
    Tax statements mailed
    The statement shows RMV, MAV, assessed value, and the tax — everything needed to screen whether an appeal can pay. Read it the week it arrives; the window is ten weeks.
  3. November 15
    Taxes due
    Full payment by November 15 earns a 3% discount; thirds fall due November 15, February 15, and May 15. Taxes are due even with an appeal pending — reductions return as refunds.
  4. December 31
    PVAB petition deadline
    Petitions go to the county clerk for the Property Value Appeals Board — renamed from BOPTA effective January 2024. Miss it and the year is locked absent narrow exceptions.
  5. February – April 15
    PVAB hearings
    Boards convene in late winter and must complete their work by mid-April. Sessions are short — the written record does the persuading.
  6. +30 days from PVAB order
    Oregon Tax Court — Magistrate Division
    Thirty days from the order's mailing to file in the Magistrate Division. Magistrate decisions can be appealed to the Regular Division within 60 days, where review is de novo; Regular Division judgments go directly to the Oregon Supreme Court. The significant commercial reductions frequently happen here.
Personal Propertyequipment & fixtures
  1. January 1
    Assessment date
    Business personal property is assessed at 100% of real market value each January 1. Inventory is exempt, and if a county total lands under the annually indexed cancellation threshold — about $24,000 for 2026–27 — the assessor cancels the assessment entirely. The return is still due either way.
  2. March 15
    Confidential Personal Property Return due
    Form 150-553-004, to each county where property sits (March 16 in 2026 — the 15th falls on a Sunday). No extensions exist, and the late penalty escalates fast: 5% of the tax through June 1, 25% through August 1, 50% after that — among the steepest non-filer curves in the West.
  3. October 25
    The tax statement is the value notice
    Oregon sends no mid-year personal property value notice. The tax statement, mailed by October 25, is the first official word on value, tax, and any penalty — leaving roughly two months to evaluate an appeal.
  4. December 31
    Property Value Appeals Board petition
    Same deadline and venue as real property. State-appraised industrial property skips the county board entirely and appeals directly to the Tax Court’s Magistrate Division (ORS 305.403) — same December 31 date.

When a deadline falls on a weekend or legal holiday it moves to the next business day. Certain valuation disputes can also reach the Tax Court outside the PVAB path — worth professional review if a December 31 was missed. SVA tracks the full calendar so clients don't have to. Personal property: returns ORS 308.290; penalties ORS 308.296; cancellation threshold ORS 308.250(4)–(5) (reset annually by DOR); industrial direct appeals ORS 305.403.

How the Bill Is Built

RMV, MAV, and the Appealable Zone

Each year MAV grows to the greater of 103% of last year's assessed value or 100% of last year's MAV — plus "exception value" for new construction and similar events. Assessed value is the lesser of that MAV or the current RMV, and the districts' rates apply to the result.

On top sits Measure 5: operating taxes can't exceed $10 (general government) plus $5 (education) per $1,000 of RMV — 1.5% combined, excluding voter-approved bonds. When rates exceed the caps, taxes "compress" down to them, local-option levies first.

The screening question for every Oregon commercial property is therefore: where does RMV sit relative to MAV, and is the property in compression? The answer determines whether a $2M value reduction is worth $30,000 a year or nothing at all.

Where Your Property Sits What a $1M RMV Reduction Does Why
The gap (lower-rate districts) Nothing. Where the district's total rate sits below the Measure 5 caps, the cap never binds — assessed value is still MAV until RMV falls below it. This is the appeal to not file.
Below MAV Assessed value falls with RMV — typically $10,000–$16,000 per year per $1M at prevailing rates. Once RMV drops under MAV, RMV is the assessed value and every dollar of reduction flows to the bill.
In compression (high-rate districts) ≈$15,000 per year per $1M — even with RMV still above MAV. Where rates exceed the caps — the norm in Multnomah County and other high-levy urban districts — the bill is capped at 1.5% × RMV, so cutting RMV lowers the cap directly.

Savings per $1M shown at typical district rates; exact results depend on your levy mix and how deep into each zone the property sits. Where the consolidated rate exceeds the caps, compression binds whenever RMV is below roughly MAV × (rate ÷ 1.5%) — which in a district taxing at 2.1% means RMV can sit 40% above MAV and an appeal still pays. SVA models the zone math on every Oregon screen — before recommending a filing.

For Developers · ORS 307.330

Two Years Off the Roll: The Construction Cancellation

Oregon will cancel the assessment on a commercial building while you build it. Under ORS 307.330, a new building, structure, or addition is exempt for up to two consecutive assessment years during construction — and machinery or equipment on site that will be installed in or affixed to it is exempt with it. The land stays on the roll; the improvement comes off.

Five conditions, all statutory: the project is in the process of construction on January 1; it is not in use or occupancy on that date; it has never been used or occupied before it; it is being built in furtherance of the production of income; and — for nonmanufacturing facilities — its first use or occupancy comes at least one year after construction commences. A project built and opened inside twelve months doesn't qualify; a multi-year build is exactly what the statute is for.

The claim is procedural, not automatic: file Form OR-AP-CACFC with the county assessor by April 1 of each assessment year claimed. The deadline is strict — the Tax Court has held the proof must be filed even when the assessor already has the information — and the only relief for a missed filing is a discretionary hardship petition to the Department of Revenue by December 15 (ORS 307.475).

The Trap What the Case Law Says
Partial use kills everything One occupied ground-floor retail space disqualified an entire mixed-use building — and the disqualifying use doesn't even have to produce income (Trendwest Resorts, aff'd 2006). Construction-related use of the space is safe; tenant occupancy, revenue operation, or non-construction storage on January 1 is not.
The 12-month clawback If a nonmanufacturing project is used or occupied within one year of breaking ground, a granted cancellation is retroactively abated and the value is billed back through the omitted-property process (ORS 307.340(1)). Opening early has a price.
Two years, chosen irrevocably On a build spanning three or more January 1 dates, you elect which two consecutive years to claim — and Georgia-Pacific (1972) holds the election can't be revoked. Claim the two assessment dates that carry the most construction value, usually the later ones.
It's a saving, not a deferral When the finished building enters the roll, its MAV is set as exception value at the same changed-property ratio whether or not you claimed the exemption — there is no recapture and no higher base later. Taxes canceled during construction are simply never owed.

Statutory basis: ORS 307.330 (exemption and conditions), ORS 307.340 (April 1 filing and abatement), ORS 307.475 (hardship relief), ORS 308.153 (exception value). Manufacturing facilities are exempt from the one-year first-use rule and its clawback. Distinct from the enterprise-zone construction-in-process exemption (ORS 285C.170), which has its own form and rules.

Where Appeals Are Won

The Grounds That Actually Move Values

Oregon rewards owners who understand the machinery. The winning work happens before and after the hearing room:

The zone screen

Model RMV against MAV and the compression math before filing. Half of Oregon's "failed" appeals were never going to pay — and a screen would have said so for free.

RMV evidence at January 1

Comparable sales and income evidence anchored to the assessment date — the case that carries PVAB and, more importantly, the Tax Court.

Compression relief

For properties at the Measure 5 caps, RMV is the bill. In high-levy districts — Multnomah County above all — much of the commercial stock sits in compression, so RMV cuts pay even with RMV above MAV.

Exception-value errors

New construction and remodels add "exception value" to MAV. An overstated addition compounds at 3% forever — and is challengeable when made.

Actual income & obsolescence

Assessor pro formas versus actual rents, vacancy, and expense loads — plus functional and economic obsolescence the mass-appraisal model can't see.

Positioning for the cycle

Because MAV rides on prior assessed values, getting RMV right today shapes what you'll owe through the next downturn — and cleans up the record before a sale.

Oregon FAQ

Common Questions

When is the deadline to appeal property taxes in Oregon?
Tax statements are mailed by October 25, and the petition to your county's Property Value Appeals Board (PVAB — renamed from BOPTA effective January 2024) must be filed with the county clerk by December 31. Boards hear petitions from roughly February through April 15.
Why didn't my Oregon RMV reduction lower my tax bill?
Because Oregon taxes the lesser of two values. Under Measure 50, your assessed value is the lower of Real Market Value (RMV) or Maximum Assessed Value (MAV, which grows at most 3% per year). In a district taxing below the Measure 5 caps, an RMV reduction that still sits above MAV doesn't move the bill. But in high-rate jurisdictions like Multnomah County, where consolidated rates exceed the 1.5% caps, the bill is capped at 1.5% of RMV — so an RMV reduction pays even above MAV. Which regime applies to your property is the first thing to check.
What is Measure 5 compression?
The Oregon Constitution caps operating taxes at $10 per $1,000 of Real Market Value for general government and $5 per $1,000 for education — 1.5% combined, excluding voter-approved bonds. When district rates exceed those caps for a property, the taxes are compressed down to the cap. For a property in compression, the cap is a function of RMV — so every dollar of RMV reduction lowers the bill at roughly 1.5%, even when RMV remains above MAV. In Oregon's high-rate urban counties — Multnomah especially — consolidated rates exceed the caps for much of the commercial stock, making compression relief routine rather than rare.
What happens after the Property Value Appeals Board decides?
A PVAB order can be appealed to the Magistrate Division of the Oregon Tax Court within 30 days of mailing. A magistrate decision can be taken to the Tax Court's Regular Division within 60 days, where review is de novo; Regular Division judgments appeal directly to the Oregon Supreme Court. Many of Oregon's significant commercial reductions happen at the Tax Court level.
When are Oregon property taxes due?
November 15, for the fiscal year that began July 1. Full payment by November 15 earns a 3% discount; payment in thirds falls due November 15, February 15, and May 15. When the 15th lands on a weekend or holiday, the deadline moves to the next business day. Taxes are due even while an appeal is pending — reductions come back as refunds.
Can Oregon cancel my property taxes while my building is under construction?
Yes — Oregon's construction-in-process cancellation (ORS 307.330) takes a new commercial building or addition off the tax roll for up to two consecutive assessment years while it's being built. Five conditions apply: under construction on January 1, not in use or occupancy on January 1, never previously used, being built to produce income, and — for nonmanufacturing facilities — first use or occupancy at least one year after construction commences. Only the improvement and the machinery or equipment to be installed in it are exempt; the land stays taxable. You must file Form OR-AP-CACFC with the county assessor by April 1 of each year claimed, occupying any part of the building disqualifies all of it, and a nonmanufacturing project occupied within twelve months of breaking ground gets its cancellation clawed back as omitted property.
What does an Oregon property tax appeal cost?
SVA works on pure contingency — no retainers, no minimums, and no fee unless your taxes are reduced. Our rate scales down from 20% to as low as 8% as the property's annual tax liability grows, versus the industry-standard flat 25%. And because of Oregon's lesser-of rule, we screen the appealable zone before filing — if an appeal can't pay, we'll tell you. See the full fee matrix.

Is your property in the appealable zone?

Send us your tax statement — RMV, MAV, and levy detail — and we'll run the zone math at no cost. If an appeal can't pay under the lesser-of rule, we'll tell you that too.
