Rate Breakdown

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

How Property Tax Works in Bond County

In Bond County, Illinois, property taxes are levied on real estate based on its appraised market value. The Bond County Assessor’s Office determines a property's value through periodic appraisals, typically conducted every five years. Any changes in market conditions, improvements, or demolition will result in a reappraisal and a corresponding change in tax liability. Once the assessor establishes a yearly value, the value is multiplied by the county’s millage rate—sometimes called a “mill” or “millage factor”—to calculate the dollar amount owed. The millage rate is expressed as a number of mills (thousandths of a dollar) per dollar of assessed value. Bond County’s millage is the sum of several components, including the county, township, school district, heritage tax, special services, and county bonds. The total millage rate is posted on the county’s website and is updated annually to reflect new levies and the repayment of bonds.

After the assessment, the county issues a tax statement that lists the total amount due for the fiscal year. The bill is typically divided into two installments: the first is due by September 30, and the second by December 1. Paying the full balance by December 1 helps you avoid interest and late‑fee charges.

Available Exemptions

Illinois offers several exemptions that can lower your property tax bill. Bond County residents can claim these through the county’s tax abatement application process. The most common exemptions are:

• Homestead (Principal Residence) Exemption: Reduces the assessed value of your primary dwelling by $15,000. You must file an application each year, and the exemption is automatically applied if you provide a copy of your state driver’s license, tax return, or other qualifying ID.
• Senior Citizen Exemption (Age 70+): Provides a $4,225 deduction on the assessed value of your main residence. Requires a stamped application on a designated form, plus proof of age and residency.
• Disability Exemption: Certain disabilities qualify for a $4,225 deduction; application requires a letter from the Department of Human Services or a physician’s statement.
• Veterans Exemption: Veterans and surviving spouses who served honorably receive a $2,000 reduction. Proof of service and marriage documentation is required.
• Other Exemptions: Bond County also offers additional special purposes exemptions, such as for certain non‑profit use, or for historic properties, though these require separate applications and documentation.

These exemptions act on the appraised value, not the tax rate, so they reduce the dollar amount that the millage rate applies to. Make sure to file the appropriate forms annually; the county processes applications in the summer to prepare the 2025 statements.

Payment Schedule & Deadlines

Bond County’s standard payment schedule is:

• First installment: due by September 30 of the calendar year.
• Second installment: due by December 1.

You may also pay the full balance by the December 1 deadline. If you do not pay the full amount by December 1, the county will add a 10% late fee on the unpaid balance and accrue interest at the statutory rate (currently 6% per annum). Late payments may also trigger an escrow requirement for future taxes, meaning a portion of your budget may be earmarked to cover taxes.

For those who have difficulty meeting deadlines, Bond County offers a payment plan that splits the balance into monthly installments over the next 12 to 24 months. All plans require an application and approval; no interest or penalty is charged unless payments are missed.

Appealing Your Assessment

If you believe your property’s assessed value is too high, you have the right to appeal. The appeal process in Bond County follows these steps:

• File a written appeal within 30 days: Submit a formal appeal to the Bond County Assessment Appeals Board (CAB) before the 30‑day window after receiving your tax statement. Attach any supporting documents (appraisal reports, photographs, comparable sales).
• Hear the board: CAB will schedule a meeting, typically within 60 days. You will present your case; the assessors will also present their findings.
• Board decision: After the hearing, the CAB will issue a written decision in writing. If the assessment is upheld, you may appeal further to the Illinois Circuit Court with any additional evidence.
• Record keeping: Keep copies of all correspondence, the board’s decision, and any adjudication orders for at least five years, as they may be required for future assessments or audits.

Timing is crucial: failing to file within 30 days will forfeit your chance to contest the assessment. A well‑prepared appeal—complete with recent sales data, expert appraisals, and a clear argument—can result in a significant reduction in your property taxes for the upcoming year.
