Oregon Property Assessor 2026: County Lookup & Tax Search

Oregon 36-County Property Search & Tax Navigator

Oregon County Property Search, RMV/MAV Records, 2026 Tax Statements & Appeals

An Oregon property tax assessor search begins with the county where the property is physically located. Oregon does not maintain one statewide public database where homeowners can search every residential parcel, tax statement and owner record. County assessment and taxation offices handle most ordinary real-estate appraisal records and county property-tax collection.

This statewide guide helps you choose the correct county, search by owner/address/account or tax lot, understand Real Market Value, Maximum Assessed Value and Assessed Value, review Measure 5 and Measure 50 limits, prepare for the 2026 tax statement, appeal through the Property Value Appeals Board, and check current deferral or business-personal-property deadlines.

What Oregon Property Owners Can and Cannot Do Yet

The values being prepared for the 2026–27 property-tax roll are based on the property’s status and value as of January 1, 2026.

The new statewide 2026–27 tax statements have not yet reached the normal fall mailing stage. Oregon law directs counties to deliver or mail tax statements on or before October 25, with the first statutory payment date on November 15.

A normal 2026 value appeal is therefore not yet filed statewide in August. In most cases, you file with the county Property Value Appeals Board after receiving the new tax statement and no later than December 31.

NEXT MAJOR STATEWIDE EVENT OCT
25 TAX STATEMENTS BY THIS DATE

Senior / disabled deferral is still actionable Late 2026 applications may still be filed through December 1 with the required late fee.

Business personal property is very late The normal return date was March 15. After August 1, Oregon law places an unfiled taxable personal-property return in the 50% penalty tier.

Values can be researched now County assessor systems can still be used to inspect current account records, maps, ownership data and prior tax history before statements arrive.

Do not search Oregon Revenue Online for your house tax bill. Oregon DOR is not the custodian of most county residential and commercial property-tax statements. Use the county where the real estate is located.

Why this is the safest statewide route: county websites and third-party software platforms change over time. Oregon DOR maintains the official county-assessor directory, so it is the safest starting point when a bookmarked parcel-search URL stops working.

County property-search workflow

How to Search an Oregon Property Assessor Record

Identify the county. Use the property’s physical location—not merely its postal city—to determine the county responsible for assessment and taxation.

Open Oregon’s county directory. Go to the Oregon DOR County Assessor Directory and select the county.

Choose Property Search, Account Search or GIS. County terminology varies. Look for Real Property, Assessment & Taxation, Property Information, Account Search, GIS or Tax Lot Search.

Search with the strongest identifier. Account number, parcel number, map/tax lot or situs address generally produces a cleaner result than owner-name searching.

Open the correct account. Match situs address, owner, legal-description clues, acreage and map location.

Review RMV, MAV and AV. These three values are essential to understanding Oregon taxation.

Move to the county tax account. Check balance, statement, installment status, receipts and delinquency separately when the search system divides appraisal and collection.

Property-search names differ widely. One Oregon county may call the tool “Property Account Search,” another “Assessment & Taxation,” another “Web Query,” and another may use Beacon, Ascend, GIS or an internally hosted portal.

Oregon Assessor Record Decoder

Field	What it means	What to do with it
Account Number	County identifier tied to the tax account.	Save it for tax-statement and payment searches.
Map / Tax Lot	Oregon cadastral identifier connecting the parcel with assessor mapping.	Use it for map research and county records.
Owner	Owner reflected on the county assessment roll.	Verify the recorded deed when legal title matters.
Situs Address	Physical property location.	Do not confuse it with the tax mailing address.
RMV	Real Market Value — assessor’s estimate of market value as of January 1.	Primary market-value figure to review for a valuation appeal.
MAV	Maximum Assessed Value — Measure 50 value limitation.	Compare it with RMV before assuming a market-value change changes tax.
AV	Assessed Value — generally the lower of RMV or MAV.	This is the ordinary taxable value used with applicable rates.
Tax Code Area	Combination of local taxing districts covering the account.	Explains why neighboring parcels can have different total rates.
Exception Value	Value related to new property or other Measure 50 exceptions.	Review construction, remodeling, partition or other account changes.
Special Assessment	Alternative taxable valuation for qualifying farmland, forestland or other programs.	Check disqualification or rollback consequences before changing use.

The Oregon value formula

RMV, MAV and AV: The Three Numbers You Must Compare

RMV — Real Market Value County assessor’s estimate of what the property would sell for in the market as of January 1 of the assessment year.

MAV — Maximum Assessed Value Measure 50 value that ordinarily cannot grow by more than 3% per year unless a statutory exception applies.

→

AV — Assessed Value Oregon generally taxes the lower of RMV or MAV. This lower figure is the Assessed Value.

Example: if RMV is $600,000 and MAV is $350,000, the ordinary Assessed Value is $350,000. Reducing RMV to $550,000 would usually not reduce the tax base because RMV would still remain above MAV.

This is why a successful market-value argument does not always save tax. Before filing an appeal, determine how far RMV would need to fall before it actually becomes lower than MAV.

Oregon Constitution — Measure 50

Why Oregon Assessed Value Often Moves Differently From Home Prices

3% Ordinary MAV growth limit Maximum Assessed Value ordinarily cannot increase more than 3% per year.

NEW Exceptions can add value New construction, major improvements, partitions and subdivisions can create additional assessed value beyond the ordinary 3% growth.

LOWER AV uses lower value Assessed Value remains the lower of RMV and MAV.

A falling housing market does not guarantee a lower tax bill. If RMV declines but stays above MAV, AV can remain tied to MAV and may still rise under the Measure 50 formula.

Oregon Constitution — Measure 5

Measure 5 Limits and Property Tax Compression

$5 Education category Measure 5 generally limits education-category taxes to $5 per $1,000 of Real Market Value.

$10 General government General-government category taxes are generally limited to $10 per $1,000 of RMV.

BOND Some bond taxes are outside Certain voter-approved general-obligation bond levies are not subject to the Measure 5 limitation.

Compression: when taxes in a Measure 5 category exceed the constitutional limit, taxes are reduced. Local-option taxes are generally compressed first, followed by proportional reductions when necessary.

There is no single Oregon property-tax rate

Why Oregon Property Tax Rates Change by Address

A parcel can be inside many overlapping taxing districts. The county places the certified rates and levies on the tax roll and calculates the property tax for the specific account.

County County government services can levy a permanent rate and voter-approved taxes.

City Incorporated parcels can be inside city taxing districts.

School School district and education taxes are a major part of many Oregon statements.

Fire / Special District Fire, library, park, port, community college and other districts can add rates.

Never publish or use one “Oregon property tax rate.” Total rates vary by tax code area, local-option levies, bonds and the taxing districts serving the parcel.

2026–27 statewide payment structure

Oregon Property Tax Due Dates, Discounts & Installments

Payment choice	First payment	Discount	Later payment
Pay in full	By the November first-payment deadline	3%	None
Pay 2/3	2/3 by first November deadline	2% on the 2/3 paid	Remaining 1/3 due May 15
Pay 1/3	1/3 by first November deadline	No discount	1/3 Feb. 15 + 1/3 May 15

OCT 25 Statement Mailing County tax statements must generally be delivered or mailed by October 25.

NOV 15* First Payment Statutory first installment date and discount deadline.

FEB 15* Second Third Second installment under the three-payment option.

MAY 15* Final Third Final ordinary installment.

1.333% Monthly Interest Oregon law charges one and one-third percent per month or fraction of a month on delinquent amounts.

2026 calendar note: November 15, 2026 falls on a Sunday. Oregon county guidance applies the next-business-day rule when a statutory due date lands on a weekend or legal holiday. Always use the exact date printed on your county’s 2026–27 statement.

Property Value Appeals Board — PVAB

Oregon 2026 Property Value Appeal Deadline

Wait for the 2026–27 tax statement. Most ordinary county valuation appeals are filed after the tax statement is received.

Review RMV, MAV and AV. Decide what value you are asking the board to change and whether the requested change would affect AV.

Gather evidence as of January 1, 2026. Use market evidence and property characteristics relevant to the assessment date.

Get the correct 2026 PVAB petition. Oregon DOR’s 2026 forms library now uses the term Property Value Appeals Board. Older references to BOPTA should be treated as legacy terminology.

File with the county PVAB clerk. Do not send an ordinary county property-value petition to Oregon DOR.

Meet the December 31 deadline. For the 2026 assessment year, December 31, 2026 is a Thursday, so the ordinary statewide deadline does not require a weekend extension.

Appeal further if needed. A taxpayer disputing a PVAB value decision can generally appeal to the Oregon Tax Court Magistrate Division within 30 days after the board’s order is mailed or delivered.

Still actionable in August 2026

Oregon Senior & Disabled Property Tax Deferral — 2026

This program is a deferral loan, not a traditional exemption. If approved, Oregon DOR pays qualifying county property taxes and records a lien against the property.

2026 household income limit $70,000 based on 2025 household income.

2026 RMV minimum cap $301,000.

Timely filing January 1 through April 15.

Late filing still open April 16 through December 1, 2026.

2026 late fee 10% of recent-roll taxes, subject to a $20 minimum and $180 maximum.

Interest Deferred amounts accrue 6% annual non-compounded interest.

August opportunity: the April 15 timely deadline is gone, but an otherwise qualifying homeowner can still submit a 2026 late application through the county assessor by December 1 with the applicable fee.

2026 change: homeowners who have owned and lived in the home for less than 17 years may now qualify when the homestead RMV is below 150% of the county’s median value of improved residential property, subject to the program’s other rules.

Open 2026 Oregon Deferral Program Review the current income, RMV, late-filing, lien and recertification rules.

Oregon is not a standard “homestead exemption” state

Oregon Property Tax Exemptions & Special Assessments

Oregon DOR states that the state has more than 100 property-tax exemption programs, but there is no statewide general homestead exemption and no statewide exemption based solely on age or income.

Farmland Qualifying agricultural land may receive special assessment instead of ordinary unrestricted market valuation.

Forestland Oregon maintains forestland and Small Tract Forestland special-assessment programs.

Historic Property Qualifying historic property can receive special-assessment treatment under applicable rules.

Veteran Benefits Oregon provides certain property-tax benefits for qualifying disabled veterans and surviving spouses; eligibility is handled through the county.

Nonprofit / Religious Qualifying charitable, religious, educational and similar organizations may receive full or partial exemption.

Enterprise Zone Qualifying business investment can receive temporary property-tax exemption under Oregon enterprise-zone rules.

Do not search for an “Oregon senior homestead exemption” and assume one exists statewide. Senior homeowners should first evaluate the deferral program and any other benefit for which they independently qualify.

August 2026 penalty warning

Oregon Business Personal Property Return

Taxable business personal property can include machinery, equipment, furniture and other tangible property used in a business. Oregon’s normal annual return date is March 15.

March 15 Normal return deadline.

After March 15 to June 1 5% of the tax attributable to the taxable personal property.

After June 1 to August 1 25% penalty tier.

After August 1 50% penalty tier.

Inventory Ordinary business inventory held for sale is generally not taxable personal property.

Household property Personal household goods and automobiles are not ordinary Oregon ad valorem personal-property tax items.

As of August 12, 2026: a required 2026 taxable personal-property return that remains unfiled has reached Oregon’s 50% penalty tier. Contact the county assessor immediately rather than waiting for the fall tax statement.

ORMAP + county GIS

Oregon Tax Lot Maps and ORMAP

ORMAP is Oregon’s statewide digital cadastral base-map program supporting the property-tax system. The usable tax-lot and parcel-search experience, however, commonly comes through the individual county assessor or GIS portal.

Tax lot Connects the assessor map with the account’s geographic parcel identifier.

County GIS Can show aerial photography, approximate parcel boundaries, zoning or other local layers.

Recorded survey / plat Use recording and survey records when exact legal dimensions matter.

Do not build or place a fence from an online assessor line. Property-tax maps are cadastral/administrative tools and should not replace a professional boundary survey.

Oregon ORMAP Information Understand the statewide property-tax map framework, then use your county assessor for the live tax-lot layer and parcel details.

Assessment ownership is not a title report

Oregon Deeds, Liens, Mortgages & Recorded Property Documents

The assessor owner field is useful for finding a parcel, but deeds and other recorded real-property instruments are ordinarily maintained through the county clerk, recorder or recording division.

Find the assessor account. Save the owner’s name, account number, map/tax lot and abbreviated legal description.

Open the county recording office. Look for County Clerk, Recording, Records or Official Records.

Search the correct document. Deeds, trust deeds, easements, liens, releases and plats answer different legal questions.

Match the legal description. Name alone can be misleading when an owner holds multiple parcels.

Order a certified copy when required. A web image or assessor-owner field may not be enough for court, title or lending use.

Oregon public-record rule: DOR itself does not keep ordinary county property-tax statements. Residential property records, deeds and mortgages should be requested from the appropriate county office.

10 Oregon property-tax answers

Oregon Property Tax Assessor FAQs

1. Is there one statewide Oregon property assessor search?

No. Oregon Department of Revenue oversees the property-tax system, but ordinary residential and commercial parcel records are maintained by county assessment and taxation offices. Identify the county and use that county’s property-search system.

2. How do I find an Oregon property by owner or address?

Open Oregon DOR’s official County Assessor directory, choose the county where the property is located, then use the county’s Property Search, Account Search, GIS or Assessment & Taxation system. Depending on the county, you may search by owner, address, account number, parcel number or map/tax lot.

3. What is Oregon Real Market Value?

Real Market Value, or RMV, is the county assessor’s estimate of market value as of January 1 of the assessment year. It is not necessarily the value actually used to calculate the tax because Oregon also calculates Maximum Assessed Value.

4. What is Maximum Assessed Value in Oregon?

Maximum Assessed Value, or MAV, is the Measure 50 value limitation. It ordinarily cannot increase by more than 3% per year unless a statutory exception applies, such as qualifying new construction, improvements, subdivision or partition.

5. Which value is used to calculate Oregon property tax?

Oregon generally uses the lower of Real Market Value and Maximum Assessed Value. The lower amount is called Assessed Value. Applicable district tax rates and other charges are then applied under Oregon’s property-tax rules.

6. When are Oregon 2026 property-tax statements mailed?

Oregon law generally requires county tax collectors to deliver or mail annual property-tax statements on or before October 25. The 2026–27 statements therefore arrive during the fall rather than in the summer assessment period.

7. When is the first Oregon 2026 property-tax payment due?

The statutory first-payment date is November 15. Because November 15, 2026 falls on a Sunday, county guidance applies the next-business-day rule. Use the exact due date printed on your county statement. Paying the full eligible tax by the first deadline earns a 3% discount, while paying two-thirds earns a 2% discount on the amount paid.

8. When is the Oregon 2026 property-value appeal deadline?

Most ordinary county value appeals must be filed with the county Property Value Appeals Board after the tax statement is received and by December 31, 2026. A further value appeal from the board can generally be filed with the Oregon Tax Court Magistrate Division within 30 days of the board’s order.

9. Does Oregon have a statewide senior homestead exemption?

No. Oregon Department of Revenue states that Oregon has no statewide general homestead exemption and no exemption based solely on age or income. Qualifying senior or disabled homeowners may instead use the Oregon Property Tax Deferral Program and may qualify for other specific programs.

10. What are the 2026 Oregon senior property-tax deferral limits?

The 2026 household-income limit is $70,000 and the statewide RMV minimum cap is $301,000. Timely applications were due April 15, but qualifying late applications can still be filed through December 1, 2026 with a fee ranging from $20 to $180 under the 2026 limits. Deferred balances accrue 6% annual non-compounded interest.
