Property owners in Portland, Oregon pay some of the highest property tax rates in the state, with the average effective rate in Multnomah County running about $23.56 per $1,000 of assessed value as of the most recent state report.1Oregon Department of Revenue. FY 2024-25 Oregon Property Tax Statistics Report Multnomah County handles billing and collection for every parcel inside the city, and your statement funds schools, libraries, fire response, parks, and a stack of other districts. The constitution caps how fast the bill can grow, but the system has enough moving parts that most homeowners end up watching the wrong number on their statement.
How Your Bill Is Calculated
Every parcel in Multnomah County carries two values set by the county assessor as of January 1 each year.2Oregon State Legislature. Oregon Revised Statutes Chapter 308 – Assessment of Property for Taxation Real Market Value is what an informed buyer would pay an informed seller in a normal transaction. Assessed Value is the number that actually drives your bill, and in most cases it sits well below Real Market Value.
Your tax equals the combined rate of every overlapping district, multiplied by each $1,000 of your Assessed Value. On a home with an Assessed Value of $300,000 and a combined rate of $23.56 per $1,000, the bill before adjustments runs roughly $7,068. That combined rate is not one levy. It stacks charges from the city, county, school district, Metro, the port, and several special service districts, and the assessor recalculates it each year to reflect new construction, changes in use, and voter-approved levies. This is also why a neighbor one school district over can pay a noticeably different amount on an identically valued home.
Why Assessed Value Usually Lags Market Value
Two constitutional amendments keep Portland property taxes from spiraling during hot housing markets, and they cap different things.
Measure 50 and the 3% Growth Cap
Measure 50, passed in 1997, limits how fast your Assessed Value can rise. The maximum Assessed Value cannot increase by more than 3% from the previous tax year.3FindLaw. Oregon Constitution Art XI Section 11 The exceptions are physical changes to the property: adding a bedroom, finishing a basement, or putting up a new structure. This is why a Portland home worth $600,000 on the market might carry an Assessed Value of $250,000 or less. The gap widens each year the market outpaces the 3% cap.
Measure 5 and Compression
Measure 5, adopted in 1990, caps the total tax that can be collected from any single property based on its Real Market Value: $5 per $1,000 of market value for education levies, and $10 per $1,000 for general government levies.4Benton County Assessment, Oregon. What Is Measure 5? When overlapping district rates push past those ceilings, a process called compression reduces them. Local option levies lose funding first. If zeroing those out isn’t enough, permanent rates get proportionally reduced until the total fits. In high-rate parts of Portland, compression regularly trims actual bills below what the nominal rates would produce.
When to Pay and How to Get the Discount
Multnomah County mails tax statements before October 25 each year.5Multnomah County. Pay Property Taxes Under Oregon law, the annual bill splits into three installments due November 15, February 15, and May 15.6Oregon State Legislature. Oregon Revised Statutes Chapter 311 – Collection of Property Taxes If a due date falls on a weekend or holiday, payment is due the next business day.
Paying early saves real money. Pay the full year by November 15 and you get a 3% discount. Pay two-thirds by that date and you get a 2% discount on the amount paid.7Multnomah County. Property Tax Payment FAQs On a $7,000 bill, the full-payment discount is about $210. That’s a better guaranteed return than most savings accounts pay over the same period.
Miss a deadline and interest accrues at 1⅓% per month, which works out to 16% annually.6Oregon State Legislature. Oregon Revised Statutes Chapter 311 – Collection of Property Taxes Interest starts the month after each installment’s due date, and partial months count as full months. You can pay online, by mail, or at designated drop-box locations.
Exemptions and Deferrals Worth Checking
Oregon offers several programs that reduce or postpone the bill for qualifying homeowners. An exemption lowers the bill. A deferral postpones it.
Senior and Disabled Homeowner Deferral
If you are 62 or older, or have a qualifying disability, Oregon will pay your property taxes on your behalf through a deferral program. The state places a lien on the home, and the deferred amount plus interest comes due when the home is sold or ownership transfers.8Oregon Department of Revenue. Oregon Property Tax Deferral for Disabled and Senior Homeowners Program For 2026, your household income for the prior year must be $70,000 or less, and the property must be your primary residence. The program helps homeowners who are house-rich and cash-poor, though the growing lien does eat into the equity heirs expect to inherit.
Disabled Veteran Exemption
Veterans certified by the U.S. Department of Veterans Affairs as having a disability rating of 40% or more can exempt a portion of a home’s assessed value. The exemption currently removes up to $27,092 of assessed value for veterans with general disabilities and up to $32,512 for those with service-connected disabilities, with the amounts increasing 3% each year. Surviving spouses who have not remarried also qualify.9Oregon Department of Revenue. Disabled Veteran or Surviving Spouse Property Tax Exemption File with the county assessor’s office. The exemption applies only to your primary residence.
Nonprofit and Charitable Property
Property owned by qualifying nonprofits and actively used for charitable, literary, benevolent, or scientific purposes can be fully exempt.10Oregon Public Law. Oregon Code 307.130 – Property of Certain Museums, Volunteer Fire Departments and Literary, Benevolent, Charitable and Scientific Institutions The critical word is “used.” Simply owning property as a nonprofit is not enough. Vacant land held for future use, or rental property generating income unrelated to the mission, generally will not qualify.
Appealing a Value That Looks Too High
If the Real Market Value on your statement looks wrong, you can challenge it. File a petition with the county’s Property Value Appeals Board (formerly the Board of Property Tax Appeals) through the county clerk between the date statements are mailed and December 31 of that year.11Oregon Public Law. ORS 309.100 – Petitions for Reduction of Property Value There is no fee at the county level.
Hearings are informal, and you do not need a lawyer. The board schedules hearings between February and April 15. Bring evidence that supports a lower value: recent comparable sales, an independent appraisal, or documentation of defects that affect marketability. The board cannot raise your value beyond what the assessor already set, so filing carries no downside risk.
If the board’s decision does not resolve the dispute, you can appeal to the Magistrate Division of the Oregon Tax Court. That step requires a $50 filing fee and runs as a more formal proceeding. Magistrate decisions can be appealed to the Regular Division and eventually to the Oregon Supreme Court, though very few residential cases go that far.
What Happens If You Don’t Pay
Oregon treats delinquent property taxes seriously, and the consequences escalate on a defined timeline. Interest at 16% per year begins the moment you miss an installment. That alone makes property tax debt some of the most expensive debt a homeowner can carry.
After three years of delinquency, the county is legally authorized to begin foreclosure.12Oregon State Legislature. Oregon Revised Statutes Chapter 312 – Tax Foreclosure and Delinquent Tax Collection The tax collector prepares a foreclosure list and, with the district attorney, files suit to foreclose the tax lien. The court can order the property sold to the county for the amount of delinquent taxes and interest owed.
Even after a foreclosure judgment, Oregon gives you a two-year redemption period to pay off the debt and reclaim the property. If you do not redeem within those two years, the tax collector deeds the property to the county and your ownership rights end permanently. Counties do foreclose. Losing a home worth hundreds of thousands of dollars over a few thousand in unpaid taxes is an outcome that plays out every year.
Charges That Aren’t Property Taxes
Several Portland charges arrive around the same time of year and get mistaken for property tax. The Arts Tax is a flat $35 per-person charge on every Portland resident aged 18 and older who has at least $1,000 in annual income and whose household income exceeds the federal poverty level.13City of Portland. Arts Tax Filing and Payment Information You owe it whether or not you own property, and the City of Portland’s Revenue Division collects it, not Multnomah County. Residents at or below the federal poverty level can request an exemption.
The Metro Supportive Housing Services tax and the Multnomah County Preschool For All tax are personal income taxes, not property taxes. They apply to Portland residents based on income, not property value. Factor them into your overall cost of owning in Portland, but do not expect to see them on your property tax statement.
