How to Appeal Your Assessment

The Treasurer’s office is responsible for mailing tax bills, collecting tax revenues and disbursing these monies to the more than 200 taxing districts in Madison County. The Treasurer’s office does not assess property values, set tax rates or make decisions in the tax appeal process.

The assessment appeal process begins at the local level with your Township Assessor or Chief County Assessor. When going through the appeal process, you, the property owner, are appealing the assessed value of your property, not the tax bill. The amount of your tax bill is determined by the various tax rates that are applied to the assessment based on the levies of various local government taxing districts. Tax rates are not an issue in the assessment appeal process, only the amount of the assessment. Once you receive your tax bill, usually in late May or early June, it is generally too late to appeal your assessment for that year’s taxes.

  • Why are my taxes higher?

    1. The taxing districts in which your property is located may have asked for more money than they received the year before. A district may ask its elected trustees for more money as result of expanding services, inflationary pressures, or lost revenue streams.
    2. If your tax bill is higher than that of a similar property in your district, your property may have been over-assessed by your Township Assessor, or the comparable property may have been under-valued by the Township Assessor.
    3. In some cases, local governments may create special exemptions or preferential assessments within your district to spur economic development. Preferential treatment, which lowers taxes on some properties, may trigger an increase in the tax burden on the remaining taxable properties.
    4. Your taxes may be higher because your assessed value has increased due to a rise in the demand for housing in your district. This may create an increase in your property's fair market value. The fair market value is determined by your local Township Assessor or by the Chief County Assessment Office.
    5. Your taxes may be higher because you did not receive an exemption or deduction that you received in the previous year. You can identify this by comparing your current tax bill to the previous year's tax bill.
