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 Tazewell County, IL

Tazewell County homeowners face an effective property tax rate of 2.111%, well above Illinois's statewide median of 1.804% and far higher than the national figure of 0.794%. Among the state's 102 counties, Tazewell ranks 20th, placing it in the upper tier for tax burden within Illinois. A median home value of $167,500 generates an annual tax bill of about $3,536. With median household income at $77,982 and per-capita income of $41,190, that bill consumes a meaningful share of earnings compared with what homeowners pay in most other parts of the country. Communities such as Morton, Green Valley, and Groveland sit within the county, and buyers there should expect property taxes that run roughly two and a half times the national norm. The rate signals a comparatively expensive tax environment, driven partly by Illinois's reliance on property taxes to fund local services.

Frequently asked questions

What is the property tax rate in Tazewell County, IL?
The effective rate is 2.11% — meaning the median tax bill equals about 2.11% of the median home value.
How much are property taxes on a median home?
On the median home ($167,500), the estimated annual bill is about $3,536.
Is Tazewell County's rate high or low?
Compare it to the state median of 1.80% and the national average near 1.1%.
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 Tazewell 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 Tazewell County assessor within the local deadline, typically with comparable sales as evidence.
