Oregon has no single property tax rate. What you actually pay depends on which taxing districts overlap your address, and those combinations change block by block. Statewide, imposed property taxes averaged $9.18 per $1,000 of real market value in fiscal year 2024–25, which works out to roughly $17.43 per $1,000 of assessed value once Oregon’s unusual valuation rules are applied.1Oregon Department of Revenue. FY 2024-25 Oregon Property Tax Statistics Report Those averages hide big county-to-county swings. Your bill is governed by two constitutional measures that cap how fast your taxable value can grow and limit the total rate districts can impose.
How Oregon Calculates Your Bill
Two numbers drive everything on your statement. The first is Real Market Value, the county assessor’s estimate of what your property would sell for on the open market as of January 1.2Multnomah County. Property Assessment FAQs The second is Maximum Assessed Value, a separate figure that can grow by no more than 3% per year from the prior year’s assessed value, with exceptions for new construction, subdivisions, and rezoning.3Oregon State Legislature. Oregon Code 308.146 – Determination of Maximum Assessed Value and Assessed Value
Your tax is calculated on Assessed Value, which is the lower of those two. Because home prices across much of Oregon have climbed well above 3% a year, most owners have an Assessed Value considerably below market. That gap is where Oregon’s property tax relief really lives, and it is why two neighbors with similar homes can owe very different amounts depending on when each last changed hands.
The system adjusts downward too. If a market slump drops your Real Market Value below your Maximum Assessed Value, your Assessed Value falls to match. When the market recovers, the taxable base climbs back at the 3% annual limit relative to the prior Maximum Assessed Value, not at whatever pace the market is setting.
The Two Constitutional Rate Limits
Everything about Oregon rates traces back to Measure 5 and Measure 50. Reading your statement without understanding both is guesswork.
Measure 5 Ceilings and Compression
Measure 5, passed in 1990, set hard ceilings on operating tax rates imposed on any individual property: education-related taxes cannot exceed $5 per $1,000 of Real Market Value, and general government taxes cannot exceed $10 per $1,000 of Real Market Value.4Oregon State Legislature. Research Report 6-99 – The New Direction of the Oregon Property Tax System Under Measure 50 When combined district rates exceed those limits, compression reduces each district’s take proportionally until the total fits. That is why some districts collect less than their permanent rate would suggest.
Measure 50 Permanent Rates
Measure 50, approved in 1997, replaced the old budget-based system. Each taxing district now has a permanent operating rate that it cannot raise.4Oregon State Legislature. Research Report 6-99 – The New Direction of the Oregon Property Tax System Under Measure 50 Voters can approve a local option levy on top, but those are time-limited: five years for operating purposes, ten years for capital projects.5Oregon State Legislature. Oregon Code 280.060 – Levy of Local Option Taxes Outside Constitutional Limitation
Why Bond Levies Push Bills Higher
Voter-approved general obligation bonds for capital construction sit outside the Measure 5 ceilings entirely. Permanent rates and local option levies are subject to the $5 and $10 limits; bond levies are not.6Oregon Department of Revenue. A Brief History of Oregon Property Taxation A school bond for new buildings adds to your bill without compression, which is why a total rate can exceed the combined $15 per $1,000 the Measure 5 limits might suggest.
Why Rates Differ Across the Street and Across the State
Every property sits in a tax code area, a zone where a particular combination of districts overlaps. One address might be inside a county, a city, a school district, a fire district, a library district, a parks district, and a water district, each with its own permanent rate stacked onto the bill.
Urbanized Multnomah, Washington, and Clackamas counties tend to carry higher effective rates because more service districts are layered on top of each other. Rural counties generally have fewer districts and lower totals, though they also tend to have fewer local option levies funding extra services. Your annual statement itemizes exactly which districts receive your money and at what rate, and most county assessor sites let you look up any property by address or account number for history and detail. That lookup is worth doing before you buy anywhere unfamiliar.
One boundary worth naming: businesses that own taxable personal property such as equipment, furniture, and inventory file a separate return with the county assessor by March 15 each year, and the same tax code area rates apply.7Oregon Department of Revenue. Property Assessment and Taxation
When Payment Is Due and How to Get a Discount
County tax collectors mail statements by October 25. You can pay in full, pay two-thirds up front, or split the bill into three equal installments due November 15, February 15, and May 15.8Oregon Department of Revenue. Property Tax Payment Procedure Oregon rewards paying early:
- Full payment by November 15 earns a 3% discount on the total bill.
- Two-thirds payment by November 15 earns a 2% discount on that portion, with the final third due by May 15.
- Three equal installments earn no discount.
On a $4,000 bill, paying in full by November 15 saves $120. If November 15 lands on a weekend or legal holiday, the deadline moves to the next business day.8Oregon Department of Revenue. Property Tax Payment Procedure Payments can be made through your county tax collector’s online portal or by mail.
What Happens If You Pay Late
Interest on unpaid property tax accrues at 1⅓% per month, which is 16% annually, and partial months count as full months.9Oregon State Legislature. Oregon Code ORS 311.505 – Due Dates; Interest on Late Payments A $3,000 delinquent balance generates roughly $40 a month in interest alone.
The bigger risk is foreclosure. Real property becomes subject to tax foreclosure once three years have passed from the earliest date of delinquency.10Oregon State Legislature. Oregon Revised Statutes Chapter 312 – Tax Foreclosure Any unpaid special assessments or fees on the tax roll for the delinquent years get swept in as well. If you are falling behind, calling the county tax office early to discuss options is far better than waiting out the interest clock.
Appealing a Value You Think Is Too High
If your Real Market Value looks wrong, you can challenge it, but the window is narrow. File a petition with your county’s Board of Property Tax Appeals by December 31 (or the next business day if December 31 falls on a weekend or holiday).11Oregon Department of Revenue. Appeals Miss it and you are locked in for the year.
You carry the burden of proof. You have to show the assessor’s value is wrong, not that your bill feels high. Recent sales of comparable properties are the strongest evidence. Structural problems and serious deferred maintenance can also support a lower value. The board will not consider financial hardship, a large year-over-year increase on its own, or arguments about the fairness of the tax system.12Multnomah County. Property Values Appeal Process
If the board rules against you, the next step is the Magistrate Division of the Oregon Tax Court. You file a written complaint, and a magistrate reviews both sides’ evidence before issuing a written decision.13Oregon Judicial Department. Magistrate Division There is no transcript of the hearing, so bring organized documentation. Magistrate decisions can be appealed to the Regular Division of the Tax Court, though few residential disputes go that far.
Exemptions and Deferral Programs
Oregon has no general homestead exemption. Simply owning and living in your home does not reduce your tax bill.14Oregon Department of Revenue. Property Tax Exemptions The exemptions that exist target specific groups.
Disabled Veterans
Veterans with a disability rating of 40% or higher from the U.S. Department of Veterans Affairs, or certified by a licensed physician, can exempt either $27,092 or $32,512 of their homestead’s assessed value. The higher figure applies to veterans with service-connected disabilities and to surviving spouses of veterans who died from service-connected causes.15Oregon Department of Revenue. Disabled Veteran or Surviving Spouse Property Tax Exemption Veterans whose disability is not service-connected face an income limit of 185% of the federal poverty level to qualify.
Senior and Disabled Deferral
Homeowners who are at least 62 or who are disabled can defer, not avoid, their property taxes. The state pays the bill on your behalf and records a lien against your home. The deferred amount accrues 6% simple interest annually. Repayment comes due when you sell, move out, or pass away.16Oregon Department of Revenue. Oregon Property Tax Deferral for Disabled and Senior Homeowners Program
For 2026, household income must be under $70,000, and the home’s real market value generally must be below either 150% of the county’s median residential value (if you have owned the home less than 17 years) or a statewide floor of $301,000.16Oregon Department of Revenue. Oregon Property Tax Deferral for Disabled and Senior Homeowners Program Applications go to the county assessor by April 15, and participants recertify every two years. Deferral can provide real relief on a fixed income, but the lien and interest reduce the equity your heirs will inherit.
