Adams County Assessment Office

The Adams County Supervisor of Assessments is the central office for property records in the county. It is located at 507 Vermont Street in Quincy. Staff handle exemption applications, keep ownership records up to date, and provide technical support to the township assessors who set values across Adams County. If you need a copy of your property record or have a question about your assessed value, this is the first place to call or visit.

Township assessors do the field work in Adams County. They visit properties, check on building permits, and update records when something changes. The Supervisor of Assessments reviews those values to make sure they line up across the board. Under 35 ILCS 200/, all real property in Illinois gets assessed at 33 1/3 percent of fair market value. That same standard applies to every parcel in Adams County, whether it is a house in Quincy or farmland in the rural townships. Farmland uses a different method based on soil productivity rather than market sales, which is relevant in a county with as much agricultural land as Adams has. The assessment office also works with the Adams County Board of Review, which hears appeals from property owners who think their values are too high.

Adams County residents can apply for exemptions that reduce the tax owed on their home. The Supervisor of Assessments processes all exemption applications for the county.

The General Homestead Exemption is the most common one in Adams County property records. It cuts $6,000 from your assessed value if you own and live in your home. No age limit applies. The Senior Citizens Homestead Exemption takes off another $5,000 for homeowners age 65 and older. You must show proof of age and ownership. The Senior Citizens Assessment Freeze locks your assessed value so it does not climb each year, but you have to meet income limits to qualify.

A Returning Veterans Homestead Exemption provides a one-time $5,000 reduction for those back from active duty.

Property Tax in Adams County

You can pay online, by mail, or in person at the Adams County Treasurer's office in Quincy. The lien date for all property in Illinois is January 1, and that is the date the county uses to set who owns the land and what it is worth for that tax year.

Adams County follows the quadrennial assessment cycle. A full reassessment happens every four years with annual adjustments in between.

The board reviews your evidence and makes a decision. That decision becomes part of your Adams County property record. If you still disagree after the board rules, you can take the case to the Illinois Property Tax Appeal Board at the state level.
