Understanding Oregon Property Taxes: A Homeowner's Guide

Oregon’s property tax system is unlike most other states, and understanding how it works can save you money, prevent surprises, and help you make smarter buying decisions. If you’re new to Oregon or buying your first home here, this guide will give you a clear picture of what to expect on your annual tax bill.

The Big Picture — Oregon’s Tax Trade-Off

Oregon is famous for having no state sales tax. That’s a real, tangible benefit that saves residents thousands of dollars annually compared to states like Washington (which has a sales tax of 6.5% + local taxes, often totaling 10%+).

The trade-off? Oregon relies more heavily on income tax and property tax to fund public services. Property taxes in Oregon are moderate by national standards — not as low as some Southeastern states, but well below states like New Jersey, Illinois, or Connecticut. And thanks to Oregon’s unique assessment system, there are built-in protections that keep your tax bill from spiking unexpectedly.

Measure 50 — The Key to Understanding Oregon Property Taxes

In 1997, Oregon voters passed Measure 50, which fundamentally changed how property taxes work in the state. Here’s what you need to know:

Assessed Value vs. Market Value

In Oregon, your property is assigned two values:

• Real Market Value (RMV) — What your home would sell for on the open market. This is updated annually by the county assessor based on comparable sales and market conditions.
• Assessed Value (AV) — The value your property taxes are actually calculated on. This is the number that matters for your tax bill.

Under Measure 50, your assessed value was reset to 90% of the 1995–1996 real market value, and it can only increase by a maximum of 3% per year, regardless of how much the real market value increases.

What This Means in Practice

If you’ve owned your Oregon home for many years, your assessed value is likely significantly lower than your real market value. I’ve seen homes with a market value of $600,000 that have an assessed value of $300,000 or less. Your taxes are based on the lower assessed value — not what your home is worth on the market.

This is a major advantage for long-term homeowners. The 3% annual cap provides predictability and protection against sudden tax increases, even when the housing market is booming.

The Exception: New Construction and Major Improvements

When a home is newly constructed, the initial assessed value is set at the real market value at the time of construction. This means new construction buyers will have a higher assessed value (and thus higher property taxes) compared to owners of similar older homes in the same neighborhood. The gap narrows over time as the 3% cap kicks in, but it’s worth factoring into your budget.

Similarly, if you make significant improvements to an existing home (additions, major renovations), the county assessor can add the value of those improvements to your assessed value.

Property Tax Rates by County

Property tax rates in Oregon vary by county, city, and taxing district. For homebuyers in the Portland metro area, here are the approximate effective tax rates you’ll encounter:

• Clackamas County (West Linn, Lake Oswego, Oregon City, Milwaukie) — Approximately 1.0%–1.2% of assessed value
• Washington County (Tigard, Tualatin, Beaverton, Hillsboro) — Approximately 0.9%–1.1% of assessed value
• Multnomah County (Portland) — Approximately 1.1%–1.3% of assessed value, typically the highest in the metro due to additional local levies

Keep in mind these rates are applied to your assessed value, not your market value. On a home with a $350,000 assessed value in Clackamas County at a 1.1% effective rate, you’d pay approximately $3,850 per year in property taxes — about $320 per month.

What’s Included in Your Property Tax Bill

Your Oregon property tax bill funds multiple services, including:

• Public schools (typically the largest portion)
• City services (police, fire, parks, roads)
• County services
• Special districts (water, sewer, library, transit)
• Voter-approved bonds and levies

Each of these entities has its own tax rate, and they’re all combined into your single annual property tax bill. The total rate varies depending on which taxing districts your property falls within.

Property Tax Exemptions and Reductions

Oregon offers several exemptions that can meaningfully reduce your property tax bill:

Veteran’s Property Tax Exemption

Oregon’s veteran property tax exemption is one of the most generous in the country. If you’re a veteran with a service-connected disability, you may qualify for an exemption that reduces your assessed value by up to $28,045 (2026 amount — this is adjusted for inflation annually). At a 1.1% tax rate, that’s roughly $308 off your annual tax bill.

For veterans with more severe disabilities, the exemption is significantly larger. If you’re a veteran, visit our veterans page for more information on benefits available to you.

Senior and Disabled Citizen Property Tax Deferral

Oregon homeowners who are 62 or older (or disabled) and meet income requirements can defer their property taxes. The state pays the taxes on your behalf, and the deferred amount becomes a lien on the property that’s repaid when the home is sold. Interest accrues at a rate set by the state, but this program can be a lifeline for seniors on fixed incomes.

Homestead Exemption

Oregon doesn’t have a traditional homestead exemption like some states. However, the Measure 50 assessment cap effectively functions as a homestead protection by limiting how quickly your tax burden can grow.

Nonprofit and Religious Exemptions

Properties owned by qualifying nonprofits, religious organizations, and government entities are generally exempt from property tax. This doesn’t apply to most homebuyers, but it’s worth noting that these exemptions can affect the tax burden distribution in a given area.

New Construction and Property Tax Assessment

Since I work in new construction, this is a question I get from buyers all the time: “What will my property taxes be on a new home?”

Here’s how it works:

• When a new home is built, the county assessor assigns it an assessed value equal to its real market value at the time of completion.
• For the first year, your assessed value and real market value will be essentially the same.
• After that first year, the 3% annual cap kicks in. If the market appreciates faster than 3% per year (which it has historically in the Portland metro), your assessed value will fall further below market value each year.

Practically speaking, if you buy a new construction home in West Linn for $500,000, your first year property taxes might be approximately $5,000–$6,000 (depending on the exact tax rate for your location). Each subsequent year, your taxes can increase by no more than 3% — even if your home’s market value jumps 5%, 10%, or more.

The Property Tax Appeal Process

If you believe your assessed value is too high, Oregon provides a formal appeal process:

• Step 1: Review your property tax statement. Check that the property details (square footage, lot size, number of bedrooms/bathrooms) are accurate. Errors here can inflate your assessed value.
• Step 2: Contact your county assessor’s office. Many discrepancies can be resolved informally.
• Step 3: File a formal appeal with the Board of Property Tax Appeals (BoPTA) by December 31 of the tax year. You’ll need comparable sales data and evidence that your assessed value exceeds the real market value or is disproportionate to similar properties.
• Step 4: If BoPTA doesn’t resolve the issue, you can escalate to the Oregon Tax Court.

Note: Under Measure 50, you can only appeal to have your assessed value reduced to the real market value. You cannot appeal for it to be lower than market value. If your RMV is already above your assessed value (as it is for most long-term homeowners), an appeal is unlikely to help.

Practical Tips for Oregon Homebuyers

• Always check the assessed value, not just the listing price. Two homes priced at $500,000 can have very different assessed values — and therefore very different property tax bills. This is especially relevant when comparing resale homes to new construction.
• Factor property taxes into your monthly budget. Your lender will calculate your total monthly payment including taxes and insurance (PITI — Principal, Interest, Taxes, Insurance). Make sure you’re comfortable with the full number.
• Remember the 3% cap. Your annual tax increase is predictable and capped. This gives Oregon homeowners a level of financial certainty that buyers in many other states don’t have.
• Check for applicable exemptions. If you’re a veteran, senior, or disabled, make sure you’re claiming every exemption available to you. These are not automatic — you must apply.
