Property Assessments in Adams County

The Adams County Supervisor of Assessments handles property values. Call (217) 277-2150 with questions. The assessor reviews each property and sets a value based on market data, sales, and property details.

Adams County follows the standard Illinois assessment formula. All property is assessed at 33.33% of fair market value under 35 ILCS 200. A home worth $180,000 would be assessed near $60,000. The state then applies an equalization factor to keep values uniform across counties. Your tax bill is based on the equalized assessed value, not the market price.

Farmland in Adams County follows a different rule. Illinois uses a soil productivity formula for agricultural land. This often results in much lower assessments than what residential or commercial land gets. The assessor uses soil types, yields, and state guidelines to set these values. Adams County has a lot of farm ground, so this comes up frequently.

If your assessment seems too high, you can appeal. File first with the Adams County Board of Review. If that does not resolve it, go to the Illinois Property Tax Appeal Board. Appeal records become part of the property's tax file.

Tax Exemptions in Adams County

Several exemptions can lower your Adams County tax bill. Apply through the assessor's office. Approved exemptions show up on your property tax record and cut your bill each year.

The general homestead exemption takes up to $6,000 off your equalized assessed value. Seniors 65 and over qualify for the senior homestead exemption, which removes up to $8,000 more. The senior freeze program locks your assessed value if household income stays below a set limit. Disabled persons can get $2,000 off, and disabled veterans may qualify for larger breaks based on their disability rating.

Some of these need to be renewed each year. Others carry forward until your situation changes or you sell the home. Check with the assessor's office in Quincy to make sure you are getting every exemption you qualify for.

County Clerk and Tax Rates

The Adams County Clerk can be reached at (217) 277-2150. The clerk extends the tax rates by dividing levy requests from each taxing district by the total equalized assessed value in that district. This is how your actual dollar amount on the tax bill gets set.

Adams County has many overlapping taxing districts. City of Quincy, school districts, park districts, library districts, fire protection, and township government all levy taxes. Each one shows up as a line item on your property tax bill. The clerk's office handles the math for every district in the county. Under the Illinois Property Tax Code (35 ILCS 200), this process is standardized, but the rates themselves vary based on local budgets and levy requests.
