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 King County, TX

In King County, Texas, buying a home may offer one of the state's more affordable entry points. The median home value here is just $52,100, and the median annual property tax bill comes to $564 — a figure that stays low largely because home prices themselves are so low. The county's effective rate of 1.083% sits below Texas's statewide median of 1.183%, ranking it 162nd out of 250 counties. Even so, it remains above the national median of 0.794%. Income levels matter too: median household income is $46,645, with per-capita income at $31,129. Together, these figures describe a place where the cost of owning a home is shaped less by the tax rate itself and more by the inexpensive housing stock, which keeps annual tax obligations far below what buyers would face in pricier parts of the state.

Frequently asked questions

What is the property tax rate in King County, TX?
The effective rate is 1.08% — meaning the median tax bill equals about 1.08% of the median home value.
How much are property taxes on a median home?
On the median home ($52,100), the estimated annual bill is about $564.
Is King 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 King 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 King County assessor within the local deadline, typically with comparable sales as evidence.
