This page helps users handle Property Tax tasks in McLean County, Illinois, including finding parcel tax information, checking payment options, and knowing which office to contact for questions.

The main self-service tool is the McLean County Property Tax Inquiry, with payment options supported by the McLean County Treasurer & Tax Collector.

McLean County Property Tax Inquiry

Use the McLean County Property Tax Inquiry to search real estate and mobile home property tax information. The system offers parcel search and mobile home search options.

  • Parcel information for a real estate property
  • Mobile home tax information

Search results are helpful for reviewing tax information, but they should not replace your actual tax bill or proof of payment.

  • Select the search type that matches the property.
  • Review the disclaimer before continuing.
  • Use the available search fields to find the property record.
  • Confirm details carefully before relying on the information for payment or follow-up.

Ownership note: For vesting or legal ownership questions, contact the McLean County Recorder’s office at (309) 888-5170.

Online payment and parcel search options

The county payment system also supports property searches and online payments. Use Govtech Tax Pro property search to search by one field only.

  • Owner name
  • Parcel number
  • Bill number
  • Property street address

For street address searches, use the number and street name for best results, such as “123 Main” instead of “123 Main Street.” Parcel number searches are limited to 10 parcels, one per line.

The payment site includes a fee calculator and registration option. A registered account can store parcel, payment, contact, receipt, and e-check receipt number information for later use.

Banks listed by McLean County accept payments only on or before each installment due date. Late payments and penalties must be paid to the Treasurer’s office.

Check payment rules

Before paying by personal check, verify the payment details carefully.

  • Make the check payable to McLean County Collector.
  • Use the current date; post-dated checks are not accepted.
  • Write the full installment amount, including any penalty or interest if late.
  • Make sure the numeric and written dollar amounts match.
  • Write the parcel number on the check.
  • Sign the check.
  • Include the payment coupon from the bottom of the bill.

Personal checks are accepted until 30 days before the tax sale. After that, payment must be made by certified funds, such as cash, cashier’s check, or money order.

Assessment, exemptions, and tax estimates

The McLean County Supervisor of Assessments handles assessment questions, exemption questions and applications, real estate bill name changes, and address changes.

McLean County explains that most property tax bills use fair market value, assessed value, equalization factor, exemptions, taxable assessed value, and the tax rate. For most parcels, assessed value is one-third of fair market value.

The basic formula is fair market value divided by three, adjusted by the equalization factor and exemptions, then multiplied by the tax rate per $100 of value.

For a county explanation of the calculation, use McLean County property tax estimate information.

Delinquent taxes and tax sale information

If property tax is not paid by the second installment due date, the Treasurer’s office sends a delinquent tax notice to the owner of record. The notice includes the total amount due for taxes, interest, and certified mailing costs.

A delinquent tax must be paid with cash, and personal checks are not accepted. The listed process includes newspaper publication, application for judgment, and tax sale.

For tax year 2025 payable 2026, the Treasurer’s office lists the tax sale date as November 6, 2026, with all dates subject to change.

Property tax exemptions and relief

McLean County lists several homestead exemptions, including General Homestead, Homestead Improvement, Senior Citizens Homestead, Senior Citizens Assessment Freeze, Disabled Persons’ Homestead, and several veterans exemptions.

Non-homestead exemptions include religious organizations, charitable organizations, educational organizations, and units of federal, state, and local government.

The Senior Citizens Real Estate Tax Deferral Program allows qualified senior citizens to defer all or part of property taxes on a personal residence. The program is handled through the Treasurer’s office and has a March 1 filing deadline for the tax year.
