Search McDonough County Tax Records

McDonough County property tax records are managed by the treasurer and assessor offices in Macomb. With about 26,920 residents, McDonough County is a mostly rural area in western Illinois anchored by the college town of Macomb. All property tax bills, assessment details, and payment records for parcels in the county are available through the treasurer's online search tool. The county courthouse in Macomb houses the key offices that handle property taxes, and most records can be accessed for free by anyone who wants to look them up.

McDonough County Online Tax Portal

The McDonough County Treasurer's tax search portal is the main way to look up property tax records in the county. You can search by owner name, property address, or parcel number. The results show current and past tax bills, assessed values, and whether taxes have been paid.

The portal is free to use. No account or login is needed. You can view multiple years of data and see the full payment history for any parcel. If you need a record for a sale, a loan, or just to check what a neighbor is paying, this is the place to start.

The McDonough County tax search tool shows tax data for all parcels in the county.

When the portal is down for maintenance, you can still get records by calling or visiting the treasurer in person at the courthouse in Macomb.

McDonough County Treasurer

The McDonough County Treasurer handles all property tax collection. The office is in the McDonough County Courthouse at 1 Courthouse Square, Macomb, IL 61455. Call (309) 833-2851 with questions about your bill or payment options.

Property taxes in McDonough County are paid in two installments. The first payment is due in the summer. The second comes in the fall. Due dates can change from year to year, so check your bill or call the office. Late payments add interest at 1.5% per month, which is set by state law under 35 ILCS 200. That penalty builds quickly on unpaid balances.

You can pay at the office with cash, check, or money order. Ask about online payment options, as some counties now accept cards through their portal. Fees may apply for card payments.

Assessments in McDonough County

The McDonough County Supervisor of Assessments is in charge of setting property values. Like most Illinois counties, McDonough County assesses property at 33.33% of fair market value. If a home is worth $90,000 on the open market, the assessed value would be about $30,000.

Once the local assessment is done, the Illinois Department of Revenue applies an equalization factor. This multiplier is meant to make sure values are fair across all 102 counties. The number that goes on your tax bill is the equalized assessed value, not the raw figure from the local assessor. The equalization process is a key part of the Illinois property tax system and it can raise or lower what you actually owe.

Think your value is wrong? You can appeal. Start with the McDonough County Board of Review. If that does not work, go to the Illinois Property Tax Appeal Board. Bring proof. Comparable sales data helps your case more than anything else.

Exemptions and Reductions

McDonough County residents can apply for several exemptions that lower property tax bills. The most common is the general homestead exemption, which cuts up to $6,000 from the equalized assessed value. You must own and live in the home to qualify.

Seniors 65 and older can get up to $8,000 off through the senior homestead exemption. The senior freeze program locks your assessed value if your income stays below a certain level. Disabled persons and disabled veterans have their own programs with different limits. All exemptions are handled through the assessor's office in Macomb. You need to apply, and most require yearly renewal.

Tax Sales and Delinquent Property

Unpaid taxes in McDonough County lead to a tax sale. The county holds these sales once a year, typically in the fall. At the sale, investors pay off the delinquent taxes and get a lien on the property. The owner then has a redemption period of two to three years under the Illinois Property Tax Code to pay back the amount plus interest and costs.

Tax sale records are public. They show which parcels went to sale, who bought the lien, and whether the owner redeemed. If you are looking at buying land in McDonough County, always check for tax sale liens before you close. Interest on delinquent taxes is 1.5% per month, and extra fees pile on once the sale process begins.
