Your bill may be too high

Illinois's average effective property tax rate is 2.07%, which is 1.16% higher than the national average of 0.91%. According to the IAAO, an estimated 30–60% of properties in high-tax jurisdictions are over-assessed. The good news: appeals are routine, low-risk, and our partner firms typically work on contingency — if they don't lower your bill, you don't pay.

How it works

Step 1

Tell us about your property

Address, current assessed value, and how to reach you. 60 seconds.

Step 2

Free review by a licensed firm

A Illinois property tax consultant or appeal attorney reviews your assessment vs. comparable sales. They tell you if an appeal is worth filing.

Step 3

You only pay if they win

If they accept your case, they handle the appeal end-to-end. Their fee is a percentage of your tax savings — if they don't lower your bill, you owe nothing.

Frequently asked

How much does the review cost?

Zero. The review is free, and there is no obligation to file an appeal. If you do file and the firm reduces your bill, their fee is a contingency percentage (typically 25–50%) of the first year's tax savings. If they don't lower it, you owe nothing.

Why is PropertyTaxRates.org doing this?

We publish property tax data for every U.S. county. We partner with licensed appeal firms in select states and earn a referral fee when a homeowner submits a successful case. Our partners are independent — we do not provide legal or tax advice ourselves.

How long does an appeal take?

Most Illinois appeals are filed before the statutory deadline and resolved within 60–180 days, depending on county and case complexity.

Will I have to go to a hearing?

Usually no. The firm handles negotiation with the appraisal district and only escalates to a formal hearing if it's the best path. They represent you start-to-finish.

What if my home is in a different state?

Right now we only run this program in Illinois. If you live elsewhere, browse our property tax data by state and check back — we're expanding.
