Is the assessment on 603 Ohio Windsor, IL 61957 fair?
Assessed at $38,655 as residential, Windsor Township. Below: how the homes near it that actually sold are assessed against what they sold for, and where this one sits among them. Two facts from the county's own record — not an opinion of value, which is what an appeal ultimately needs and what we will give you if you ask.
How the neighbourhood is assessed
32.2%
of what it sold for (middle half 27.1–39.5%); the statute says 33.33%
This parcel among them
26 of 39
sold homes within half a mile are assessed below it
Their assessed values
$28,290
median; $8,977 to $57,833. This parcel: $38,655
Your own sale is the strongest evidence there is: at 48.3% of what you paid, this parcel is assessed well above the 32.2% the neighbours who sold are. That is worth asking about.
This parcel's own recorded sale: $80,000 in Feb 2026; the current assessment is 48.3% of that. A recent arm's-length sale of the property itself is the evidence a Board of Review weighs most.
The homes that sold near it
Arm's-length sales recorded with the county in the last 3 years, nearest first, with the assessed value the county carries for each today. Whether any of them is like this house — size, age, condition — is the question the record cannot answer and an appeal turns on.

Assessed value $38,655 × the 2024 rate of 6.01% for tax code 24002 (Windsor Township), billed in 2025.
The owner-occupied figures take the General Homestead ($6,000 off the assessed value) and Senior Citizens ($8,000) exemptions; the senior freeze, veterans’ and home-improvement exemptions are not shown and can lower a bill further. The rate is the newest the clerk has published; the next levy will move it a little, and a sale can prompt a reassessment. Sources: Shelby County Clerk, Tax Codes and Districts Catalog, 2024 (payable 2025) and the assessor's current file. The bill of record is the treasurer's: Erica Firnhaber, Shelby County Treasurer.
How an appeal actually works here
- Talk to the assessor first. Many differences are a record error — a garage that came down, a square footage that was never right — and get fixed with a phone call, no appeal needed.
- The county Board of Review. A written complaint in the window after the township's assessments are published each year; the office can tell you the dates for this township. Evidence: a recent appraisal, comparable sales, or comparable assessments (the equity argument — the table above is where that starts).
- Then the state. A Board of Review decision can go to the Illinois Property Tax Appeal Board within 30 days of the decision — its forms and rules are on ptab.illinois.gov.
