Oregon Property Tax Bills: What Homeowners Should Know in 2026

It’s that time of year again. Oregon homeowners are opening their mailboxes to find their annual property tax statements, and for many, the first reaction is a familiar one: Wait, why is this so much?

Property taxes aren’t exactly anyone’s favorite topic, but the annual statement contains some useful information beyond the amount owed. It offers a snapshot of a home’s assessed value, shows how local tax dollars are distributed, and can help homeowners plan for future expenses.

For homeowners in Portland and the surrounding communities in Multnomah, Washington, and Clackamas Counties, understanding a few key details can make that annual envelope a lot less intimidating.

What Is an Oregon Property Tax Statement?

Every fall, Oregon counties send property owners an annual statement outlining their property taxes for the current tax year. These statements typically arrive in October, with the first payment due in November.

The statement includes the property’s real market value, assessed value, total taxes owed, payment deadlines, and a breakdown of the local taxing districts receiving those funds.

But here’s where things get interesting: the value used to calculate property taxes isn’t necessarily what a home would sell for today.

Why Is a Home’s Assessed Value Different From Its Market Value?

Oregon has a somewhat unusual property tax system, thanks in large part to Measure 50, which voters approved in 1997.

The system uses three different property values:

Real Market Value (RMV): The county assessor’s estimate of what a property would sell for on the open market as of January 1 of the assessment year.

Maximum Assessed Value (MAV): A value established under Oregon’s property tax laws that generally cannot increase by more than 3% annually, unless certain changes to the property occur.

Assessed Value (AV): The lower of the real market value or maximum assessed value. This is the value used to calculate most property taxes.

That distinction matters. A Portland home could have a real market value of $650,000 but an assessed value of just $350,000. Its property taxes would generally be calculated using the lower number.

It’s also why two seemingly similar homes on the same street can have very different property tax bills.

And while the county’s estimate provides one perspective on a home’s value, it isn’t a substitute for a current market analysis. Actual selling prices depend on neighborhood trends, comparable sales, condition, updates, and what buyers are willing to pay.

Why Do Oregon Property Taxes Increase?

One common misconception is that Oregon property taxes can only increase by 3% each year.

In reality, the 3% limit generally applies to the growth of a property’s maximum assessed value, not the total tax bill. Several factors can cause a homeowner’s property taxes to increase, sometimes by more than 3%.

Local voter-approved bonds and levies are one reason. Property taxes help fund schools, fire departments, libraries, parks, public safety, and other community services. When voters approve new funding measures, those costs can appear on property tax statements.

Certain property improvements can also affect assessed values. Major additions, new construction, and qualifying renovations may increase a property’s maximum assessed value beyond the usual annual limit. Routine maintenance and smaller projects generally don’t have the same effect.

Changes to tax rates and the expiration of existing levies can influence the total bill, too.

For homeowners who notice a jump in their taxes, comparing the current statement with last year’s is a good place to start. Changes in assessed value and local taxing district charges can help explain the difference.

Does Receiving a Property Tax Bill Mean a Payment Is Due?

Not necessarily!

Many homeowners pay property taxes through an escrow account managed by their mortgage lender. A portion of each monthly mortgage payment is set aside for taxes and insurance, and the lender makes the property tax payment when it’s due.

In Oregon’s Portland-area counties, the color of the statement can offer a helpful clue.

A yellow statement generally means a mortgage company or the Oregon Department of Revenue has requested the tax bill and may be handling payment.

A green statement generally indicates that the homeowner is responsible for paying the county directly.

However, homeowners shouldn’t rely on the color alone. Anyone with a mortgage, particularly one that has recently been refinanced, transferred, or paid off, should confirm payment arrangements with their loan servicer. Ultimately, property owners remain responsible for ensuring their taxes are paid.

When Are Oregon Property Taxes Due in 2026?

For the 2026–2027 property tax year, the first payment deadline is November 16, 2026. Since November 15 falls on a Sunday this year, the deadline moves to the following business day.

Oregon homeowners paying their taxes directly have a few options.

Paying the full amount by November 16 qualifies for a 3% discount. Paying two-thirds by that date qualifies for a 2% discount, with the remaining balance due in May.

Homeowners can also choose three installments, with payments due November 16, 2026, February 16, 2027, and May 17, 2027. This option does not include a discount.

Exact amounts, instructions, and available payment methods appear on each county’s statement.

What If a Property’s Assessed Value Seems Wrong?

An annual property tax statement is also an opportunity to review the county’s valuation of a home.

If the real market value appears inaccurate, homeowners may be able to appeal through their county’s Property Value Appeals Board. For the 2026 tax year, the appeal deadline is December 31, 2026.

There’s an important distinction, though. Successfully challenging a property’s real market value won’t necessarily reduce its property taxes. Because Oregon generally calculates taxes using the lower of the real market value and maximum assessed value, a reduction in market value may have little or no effect on the actual bill.

Homeowners considering an appeal should review the county’s assessment information and gather relevant evidence, such as comparable property sales or documentation of property conditions.

Frequently Asked Questions About Oregon Property Taxes

Why do two similar Portland homes have different property taxes?

Oregon’s property tax system considers each property’s historical assessed value, qualifying improvements, and applicable taxing districts. Even homes with similar current market values can have significantly different tax bills.

Can property taxes increase even if a home’s market value decreases?

Yes. Oregon’s maximum assessed value can generally increase even when real estate prices decline. Changes in local taxes and levies may also affect the total amount owed.

Where can Oregon homeowners look up their property tax information?

Homeowners can review property values, annual statements, and payment details through their county’s assessment and taxation office:

Multnomah County Property Taxes

Washington County Assessment & Taxation

Clackamas County Assessment & Taxation

A Little Knowledge Goes a Long Way

Property tax statements may not be the most exciting mail of the season, but they’re worth more than a quick glance before being filed away.

Understanding how property taxes work helps homeowners anticipate expenses, evaluate potential improvements, and make informed decisions about one of their largest investments.

And even for homeowners who are perfectly happy staying put, there’s value in keeping an eye on the bigger picture. Understanding a home’s market value, how the neighborhood is changing, and what those trends might mean down the road makes it easier to plan for the future, whatever that future looks like.
