Search Marshall County Property Tax Records

Marshall County property tax records are maintained by the treasurer and supervisor of assessments in Lacon. This small north-central Illinois county sits along the Illinois River and has about 11,647 residents. The treasurer collects taxes and the assessor determines property values. You can look up tax bills, check assessed values, and find payment details for any parcel online or by contacting the courthouse. Both offices work together to keep property tax records current for every piece of land in Marshall County.

Online Tax Search Tool

The Marshall County tax search portal lets you look up property tax records at no cost. Search by owner name, address, or parcel number. The results show the current bill amount, assessed value, exemptions, and payment status. No login is needed.

Each result includes a line-by-line breakdown of taxing districts. You can see exactly how much goes to local schools, the road district, fire protection, and other bodies. The portal keeps multiple years of records on file. This makes it a good tool for tracking how taxes on a specific parcel have changed. Print results right from the page or save a copy for your own records.

The system is the same one used by the treasurer's office internally. Data stays up to date through the collection cycle.

Marshall County Treasurer

The Marshall County Treasurer handles all tax collection. The office is in the Marshall County Courthouse in Lacon. Staff can answer questions about your bill, take payments, and print receipts. Contact the office for current hours.

Payment options include in-person at the courthouse and by mail. For mail payments, include your bill stub and a check payable to the Marshall County Treasurer. The treasurer also oversees the annual tax sale for delinquent parcels. Under the Illinois Property Tax Code (35 ILCS 200), unpaid taxes gain interest at 1.5% per month. After a parcel stays delinquent long enough, it goes to the tax sale. A buyer pays the owed amount and earns interest until the owner redeems. The redemption period usually lasts two to three years.

If you miss a payment, call the treasurer's office right away. They can tell you the exact penalty amount and help you understand your options before the parcel heads to sale.

Property Assessments

Marshall County assessments follow the state standard of 33.33% of fair market value. If your home is worth $100,000, the assessed value would be about $33,333. Township assessors handle the initial valuations. The supervisor of assessments in Lacon reviews them and makes corrections where needed.

After local assessments are done, the Illinois Department of Revenue applies an equalization multiplier. This keeps all counties at the same statutory level. Marshall County's multiplier changes each year based on local assessment accuracy. The equalized assessed value, or EAV, is the number that tax rates are applied to when the county clerk extends bills.

Farmland in Marshall County is assessed differently. Agricultural parcels use a productivity-based formula instead of market value. This usually results in a much lower assessed value per acre than what the land might sell for. The method is set by state law and applies across Illinois.

Available Exemptions

Several exemptions can lower your tax bill. The general homestead exemption reduces the EAV by up to $6,000 for homes where the owner lives. The senior homestead exemption gives seniors 65 and older an extra $8,000 reduction. A senior freeze locks the EAV at the base year level for qualifying low-income seniors.

Disabled persons can get $2,000 off. Disabled veterans may qualify for larger amounts based on their disability rating. All exemptions must be applied for through the assessor's office in Lacon. Some need yearly renewal. Check with the office to make sure yours stays active. Approved exemptions show up on the Marshall County property tax record for each parcel.

Payment Schedule and Penalties

Taxes in Marshall County are paid in two installments. The first is due in summer. The second follows in fall. Exact dates are on your bill. Taxes are paid in arrears. You pay in 2026 for the 2025 tax year.

Late payments face a 1.5% monthly penalty. Both installments missed? The parcel goes on the delinquent list. The county sells the back taxes at an annual tax sale. Buyers at the sale pay your debt and collect interest when you redeem. The redemption window is typically two to three years. If the owner fails to redeem in time, the tax buyer can petition for a deed to the property. The whole timeline shows up in Marshall County property tax records.

Appealing Your Assessment

Property owners can appeal if the assessment seems wrong. The Marshall County Board of Review is the first stop. Gather sales data for similar properties nearby. An appraisal helps too. The board meets during a set period, usually in fall. File before the deadline or you lose the chance for that year.

If the Board of Review turns you down, go to the Illinois Property Tax Appeal Board (PTAB). PTAB handles appeals from all counties. A successful appeal brings down the assessed value and reduces the tax bill. The result stays on the property's tax record going forward.

Other Property Records

The Marshall County Recorder keeps deeds, mortgages, and liens on file. These documents connect to the property tax system because they show who owns each parcel. When land sells, the recorder logs the deed and the assessor updates the owner name in the tax records.

You can also check the Illinois Property Tax Public Inquiry site for data from counties across the state. For Marshall County details, the local search portal is generally more current. The Illinois Property Tax Code governs every part of the tax process statewide.
