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 Franklin County, WA

In Franklin County, Washington, the median home value sits at $379,300, and the annual real-estate tax bill that goes with it averages $2,750. That works out to an effective rate of 0.725%, which lands below Washington's statewide median of 0.730% and ranks the county 21st of 39 on property taxes. Buyers weighing a move to Pasco or the smaller communities of Eltopia and Kahlotus will find the national picture even more favorable: the U.S. median effective rate is 0.794%, so this county undercuts both benchmarks. Household income here runs $86,714, while per-capita income is $33,959. Pairing those earnings with a tax bill near $2,750 means housing costs stay within reach for many buyers, and the county's middling state ranking suggests taxes here are neither a standout bargain nor a heavy drag.

Frequently asked questions

What is the property tax rate in Franklin County, WA?
The effective rate is 0.72% — meaning the median tax bill equals about 0.72% of the median home value.
How much are property taxes on a median home?
On the median home ($379,300), the estimated annual bill is about $2,750.
Is Franklin 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 Franklin 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 Franklin County assessor within the local deadline, typically with comparable sales as evidence.
