Property Tax in Thurston County, Washington
In Thurston County, Washington, the typical homeowner pays $4,043 a year in property taxes on a home worth a median of $451,500. The figures on this page are the Census Bureau's published medians (US Census Bureau, American Community Survey (ACS) 5-year estimates, 2023), shown exactly as released.
What the Thurston County numbers mean
A median is the middle household: half of owner-occupied households in Thurston County pay more than $4,043, and half pay less. Your own bill is set by your home's assessed value, the exemptions you qualify for, and the local taxing districts your property sits in — so individual bills vary widely around the median.
Dividing the median tax by the median home value gives a derived effective rate of 0.90% for Thurston County. It is an estimate built from two survey medians, not the county's official rate, but it is a fair way to compare the local tax burden with other counties where home values are very different.

How the tax is worked out
Think of the final bill as three ingredients: the assessed value of the property, the exemptions subtracted from it, and the combined rate of every district the property sits in. Thurston County's medians imply a derived rate of 0.90%; applied illustratively, a $400,000 home would owe about $3,580 a year, or around $298 a month spread evenly. Individual properties depart from the illustration in both directions.
Checking your assessment in Thurston County
If your bill looks wrong, work through these steps:
1. Get your property record card from the assessor and check the basics — living area, lot size, bedrooms, condition, and any exemptions you should have.
2. Compare your assessed value with recent sale prices of similar homes in Thurston County.
3. Talk to the assessor's office informally first; clear errors are often fixed without a hearing.
4. If needed, file a formal appeal with the local review board before the deadline on your assessment notice, with your evidence attached.
5. Keep paying the bill as issued while the appeal runs, unless your notice says otherwise — unpaid taxes accrue penalties regardless of an appeal.
