Access Clark County Property Tax Records

Clark County property tax records are handled by the county treasurer and supervisor of assessments in Marshall. Sitting along the Indiana border in east-central Illinois, Clark County is home to about 15,300 people. The county has a mix of farmland and small communities, with Marshall serving as the main hub for government business. You can search tax bills, view assessed values, check payment history, and find exemption details using the county's online portal or by visiting the courthouse in Marshall.

Online Tax Search Portal

Use the Clark County tax search portal to look up property tax records for any parcel. You can search by owner name, address, or parcel number. Results show tax bill amounts, assessed values, exemptions, and payment status. The tool is free and public.

Each record breaks down the bill by taxing district. Schools, fire protection, road districts, townships, and other local bodies each get their own line. Clark County is not large, but the number of overlapping districts still creates variation in rates across different parts of the county. The portal also has data from prior years. You can see how your bill has changed over time and verify that past payments were applied correctly. Save or print from the page if you need a copy.

The statewide Illinois Property Tax Public Inquiry site can also pull up Clark County data. The local portal tends to be more current, so start there for the freshest numbers.

Clark County Treasurer

The Clark County Treasurer collects property taxes on every parcel in the county. The office is in the Clark County Courthouse in Marshall, IL 62441. Call with questions about your bill or payment options. Hours are weekdays during normal business hours.

You can pay at the courthouse, mail a check, or use the online system. Mail payments should include the stub from your bill and a check payable to the Clark County Treasurer. The treasurer is also in charge of the annual tax sale. Under the Illinois Property Tax Code (35 ILCS 200), unpaid taxes draw 1.5% monthly interest. Delinquent parcels eventually go to tax sale, where investors pay the back taxes. The owner then has a redemption period, typically two to three years, to pay everything back with interest. If they don't redeem, the buyer can petition for a deed.

Property Assessments

Clark County property is assessed at 33.33% of fair market value. This is the same rate used across Illinois outside Cook County. A home valued at $90,000 on the market would have an assessed value of about $30,000. Township assessors in Clark County do the initial valuation work, and the supervisor of assessments reviews everything for accuracy.

Each year, the Illinois Department of Revenue sets an equalization multiplier for the county. This adjusts local assessments to meet the 33.33% target. The resulting equalized assessed value (EAV) is what your tax rate applies to. For agricultural land, Illinois uses a productivity-based system that ties values to soil quality instead of sale prices. Clark County has substantial farm acreage, so this method covers many parcels. Contact the assessor's office in Marshall if you need details about how a specific property was valued.

Exemptions Available

Several exemptions can lower your Clark County tax bill. Apply through the supervisor of assessments in Marshall.

The general homestead exemption cuts up to $6,000 from the EAV of owner-occupied homes. Seniors 65 and older qualify for an additional $8,000 through the senior homestead exemption. The senior freeze locks EAV at a base year for qualifying low-income seniors. Disabled persons can get a $2,000 reduction, and disabled veterans may get much larger exemptions depending on disability level. Some of these need to be renewed each year. Stay on top of the paperwork so you don't lose your exemption. Each approved exemption shows on the Clark County property tax record for that parcel.

Payment Schedule and Late Fees

Clark County property taxes come in two installments. The first is due in summer. The second is due in fall. Exact dates shift each year, so check the bill. Illinois taxes are paid in arrears. Your 2026 bill covers the 2025 tax year.

Late payments incur a 1.5% monthly penalty. That adds up quickly if you let it go. Missing both installments puts the parcel on the delinquent list. The county sells those unpaid taxes at its annual sale. Tax buyers pay the amount owed and earn interest once the owner redeems. The redemption period is usually two to three years. If the owner does not redeem, the tax buyer can seek a tax deed to the property. All of this is recorded in Clark County property tax records and can be looked up through the portal or at the courthouse.

Assessment Appeals

Think your property is assessed too high? You can appeal. Start at the Clark County Supervisor of Assessments office. They will tell you the filing deadline and what evidence to bring. Comparable sales are the strongest proof. An independent appraisal can also help your case.

The Clark County Board of Review hears appeals at the local level. If their ruling doesn't go your way, take the case to the Illinois Property Tax Appeal Board (PTAB). PTAB is a state agency that reviews cases from all counties. A successful appeal lowers your EAV and your future bills. More details on the state process are available from the Illinois Department of Revenue.

Tax Rate Calculation

The Clark County Clerk is responsible for calculating tax rates. After assessments are set, each taxing district submits a levy. The clerk divides each levy by the total EAV in that district to get the rate. School levies are usually the largest component. Fire, library, road, and township levies fill out the rest.

Because taxing districts overlap differently across the county, two parcels with the same EAV can have very different total rates. The rate on your bill reflects the combined levies of every district that covers your parcel. If something looks wrong, the clerk's office in Marshall can walk you through the calculation.

Communities in Clark County

Marshall is the county seat and the center of government services. Other communities include Casey, Martinsville, and Westfield. None has its own tax collection office. All property tax business runs through the county offices in Marshall, and the same online portal covers every parcel in Clark County.
