Kendall County Property Tax Search Online

The Kendall County tax search portal is the primary way to look up property tax records from home. The system uses a DevNet Wedge interface where you can search by owner name, property address, or parcel number. Results show the tax bill amount, payments made, and how the bill breaks down by taxing district. It is free to use and does not require a login.

When you pull up a parcel, you can see the full history of Kendall County property tax records for that property. The tool shows the assessed value, the equalized assessed value after the state multiplier is applied, and the total tax rate for the property's location. Each taxing body is listed with its share of the bill. This makes it easy to see exactly where your property tax dollars go in Kendall County.

Kendall County sends out only one property tax bill per year. This is different from some other Illinois counties that send a separate bill for each installment. Your single bill has two payment stubs. You pay the first installment by the first due date and the second by the later date. Both due dates are printed on the bill and posted on the county website.

How Kendall County Property Taxes Are Calculated

The tax calculation in Kendall County follows the same steps used across Illinois under 35 ILCS 200. First, the assessor sets the market value. Then 33.33% of that value becomes the assessed value. The Illinois Department of Revenue may apply an equalization factor (also called the state multiplier) to bring the county's assessments in line with the statewide standard. After that, exemptions are subtracted. The result is the taxable value.

Next, the county clerk applies the tax rates from each local taxing body. Schools, the city or village, the township, park districts, library districts, and other units each set a levy. The total of all these rates is the composite tax rate for your property's location. Multiply the taxable value by the composite rate and you get the tax bill. All of this shows up in your Kendall County property tax records.

Delinquent Taxes and Tax Sales

If you do not pay your Kendall County property taxes on time, interest starts at 1.5% per month. After the taxes go unpaid through the full collection cycle, the treasurer holds a tax sale. At the sale, investors bid on the right to pay your back taxes. The property owner then has a redemption period, usually 2 to 2.5 years, to pay back the amount plus interest and fees under 35 ILCS 200.

Delinquent tax records are public. They show up in the Kendall County property tax search tool. If you are buying a property, always check for delinquent taxes and tax sale activity before closing. Contact the Kendall County Treasurer at (630) 553-4124 for the current status of any parcel.
