What you'll pay, at a glance

Property taxes are the largest local tax most homeowners pay. The effective rate measures the real tax bill as a share of home value — a more useful number than the nominal “mill rate,” because assessment practices vary county to county.

How this is calculated

The effective property tax rate is the median real-estate tax bill divided by the median home value — both for owner-occupied homes, from the U.S. Census Bureau's American Community Survey (ACS 5-year estimates)1. Median income is also from the ACS1. Federal and state income-tax figures use IRS2 and Tax Foundation3 data.

About Benton County, OR

Benton County’s effective property tax rate of 0.952% sits well above both the Oregon median of 0.746% and the national figure of 0.794%. That gap places the county third among Oregon’s 36 counties for property tax rate, meaning only two others levy more heavily relative to property value. The practical result shows up in the median annual bill of $4,884, calculated against a median home value of $513,000. Households here earn a median of $77,702, with per-capita income at $45,624, so the tax load lands in a county that is comparatively affluent but also carries a steeper-than-average rate. Corvallis, the largest community in the county, anchors much of that housing stock. Anyone weighing a move here should recognize that property taxes run higher than the state and national norms, a signal of strong local levies and robust public investment rather than an anomaly.

Frequently asked questions

What is the property tax rate in Benton County, OR?
The effective rate is 0.95% — meaning the median tax bill equals about 0.95% of the median home value.
How much are property taxes on a median home?
On the median home ($513,000), the estimated annual bill is about $4,884.
Is Benton County's rate high or low?
Compare it to the state median of 0.75% and the national average near 1.1%.
How does the effective rate differ from my mill rate?
A mill rate is the nominal levy per $1,000 of assessed value. The effective rate reflects what you actually pay after exemptions and assessments — it's the median tax bill as a share of median home value, so it better predicts your real cost.
Will a reassessment raise my tax bill?
Not necessarily. If your home's assessed value rises, your bill can go up, but only if the mill rate and exemptions stay flat. Contact the Benton County assessor's office to review your current assessment.
Can I appeal my property tax assessment?
Yes. Most counties allow an appeal when you believe the assessed value exceeds the market value. File with the Benton County assessor within the local deadline, typically with comparable sales as evidence.
