Rate Breakdown

Property taxes in Coles County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Coles County

In Coles County, property taxes are levied on the assessed value of real estate. The county assessor’s office conducts annual valuations in March, assigning each property a market value that reflects its fair market price as of the previous year’s closing date. The assessed value is then multiplied by the county’s effective millage rate to determine your tax bill.

The millage rate in Coles County is the sum of several components: the state base rate, the county rate, and rates set by school districts, municipal governments, and special tax districts (e.g., water or fire protection). For 2025, the effective millage rate hovers around 79‑80 mills, though it can shift annually with local budget decisions. You can view the exact rates on the County Assessor’s website or by calling the office directly.

Available Exemptions

• Homestead Exemption – 20% reduction (or up to $10,000 of assessed value) for primary residences.
• Senior Citizen Exemption – 10% reduction for individuals 65 ½ years or older with a homestead assessment.
• Veteran Exemption – 20% reduction for disabled veterans and $10,000 for non‑disabled veterans; requires proof of veteran status and disability documentation.
• Disability Exemption – 10% reduction for disabled taxpayers, verified through VA or state disability agencies.
• Other Local Exemptions – Coles County offers limited “public safety” or “agricultural use” exemptions for qualifying properties; check the county’s exemption handbook or website for details.

To receive any exemption, submit a completed application to the Coles County Assessor, attaching required documentation (birth certificate for senior status, VA letter for veteran status, service record, etc.). Applications typically open at the start of the year and close in early spring.

Payment Schedule & Deadlines

Property taxes in Coles County are paid twice a year:

• First installment: due on July 1st. It covers taxes for a year starting August 1st.
• Second installment: due on December 15th. This covers taxes beginning the following year’s August 1st.

Early payment is encouraged; any payment made within the first 10 days of an installment receives a small grace period but no discount. If late, a 5% per month penalty applies, and after 90 days, homeowners risk delinquent tax liens and could face foreclosure proceedings. It is advisable to set up automatic payments through the county’s online portal to avoid missing deadlines.

Appealing Your Assessment

If you believe your property’s assessed value is incorrect, you can file a challenge within 30 days of the official notice of assessment, which the assessor sends by mail in March. The appeal process involves:

• Submitting a written petition with supporting evidence (recent comparable sales, a professional appraisal, or photographs of notable property changes).
• Attending a hearing before the Coles County Assessment Appeals Board, usually held in the county courthouse.
• If the board denies the appeal, you may request a re‑assessment after a two‑year interval as mandated by Illinois law.

All appeal documents should be filed electronically via the county’s portal or by mail to the Assessor’s office. Timely submission and thorough documentation greatly improve the chances of a favorable outcome.

Whether you’re estimating your tax load or planning to file for an exemption, familiarizing yourself with these steps can help you stay compliant, reduce costs, and ensure that your property taxes accurately reflect your property’s true value.
