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 Grays Harbor County, WA

Grays Harbor County’s effective property tax rate of 0.800% sits above Washington’s statewide median of 0.730%, placing it 9th among the state’s 39 counties. That ranking signals a heavier reliance on property taxes than most Washington counties, though the gap with the state figure is narrow. Against the national median of 0.794%, the county’s rate is only slightly higher, so it lands close to the middle of the national picture rather than standing out as an outlier. A median home value of $314,000 produces a median annual tax bill of $2,512. With median household income at $64,414 and per-capita income at $34,290, the tax load reflects a county where home values and earnings are moderate compared with higher-cost parts of the state. Aberdeen, the largest of the county’s principal communities, anchors a region where property taxes run a bit above Washington norms but roughly in line with the country overall.

Frequently asked questions

What is the property tax rate in Grays Harbor County, WA?
The effective rate is 0.80% — meaning the median tax bill equals about 0.80% of the median home value.
How much are property taxes on a median home?
On the median home ($314,000), the estimated annual bill is about $2,512.
Is Grays Harbor County's rate high or low?

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 Grays Harbor 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 Grays Harbor County assessor within the local deadline, typically with comparable sales as evidence.
