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 Thomas County, KS

Buyers looking at Thomas County, Kansas will find a housing market where the median home value sits at $172,700, and the annual property tax bill on that home comes to about $2,440. That works out to an effective rate of 1.413%, which lands beneath Kansas's statewide median of 1.506% and places the county 74th among the state's 105 counties for property tax rate. Against the national median of 0.794%, though, the county's rate is noticeably higher. Households here earn a median of $71,325, with per-capita income at $39,446, so the yearly tax obligation equals roughly 3.4% of median household earnings. For anyone weighing a move, the combination of below-average home prices and a tax rate that undercuts much of Kansas may offset the steeper comparison with national figures.

Frequently asked questions

What is the property tax rate in Thomas County, KS?

Is Thomas County's rate high or low?

How does the effective rate differ from my mill rate?

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