Kendall County Property Tax Payment Methods and Deadlines

Late payments are charged a 1.5% penalty starting the day after the due date, and an additional 1.5% is added every 30 days the bill remains unpaid. Property owners who do not receive a bill in the mail remain responsible for paying on time, since non-receipt does not pause penalty accrual.

Kendall County Property Tax Exemptions for Seniors and Veterans

Kendall County offers several exemption programs that reduce the taxable value of a home or remove a portion of the tax bill entirely. The general homestead, senior homestead, senior assessment freeze, long-time occupant, disabled persons, and returning veterans exemptions each carry their own eligibility rules and application steps. To qualify for any homestead-related exemption, the property address must appear on the applicant’s current Illinois driver’s license.

• Senior Citizens Homestead Exemption – for age 65+ residents
• Senior Citizens Assessment Freeze – freezes the EAV at the year of application

Kendall County Property Tax Assessment Notice Explanation

The annual assessment notice mailed to property owners contains the parcel identification number, the prior year’s assessed value, the current year’s assessed value, the township code, and any exemptions already applied. A change in assessed value does not always translate to a change in the tax bill, since tax rates shift independently each year based on local levy requests. Owners should review each line for accuracy, including property description, square footage, lot size, and exemption status.

• Parcel Identification Number (PIN) – unique 14-digit code
• Prior Year Assessed Value – baseline for comparison
• Current Year Assessed Value – new value after township review
• Property Class Code – residential, commercial, agricultural, etc.
• Exemptions Applied – current exemptions on file
• Township Code – the township where the parcel sits

Kendall County Property Tax Lien Details

Property tax liens attach to real property automatically when taxes become delinquent, and the lien secures the unpaid balance plus penalties and interest. The lien remains attached to the parcel until the debt is fully satisfied, and a tax lien can complicate a sale or refinance since title companies require the lien to be paid off before issuing a clear title. Buyers purchasing property in Kendall County should request a tax status report before closing.

• Automatic attachment – upon first missed installment
• Survives ownership transfer – follows the parcel, not the owner
• Title impact – must be cleared before sale or refinance
• Tax sale trigger – typically two years of delinquency
• Release of lien – recorded once balance is paid in full

Kendall County Property Tax Settlement Offers

Property owners with delinquent taxes sometimes receive settlement offers that consolidate multiple years of unpaid taxes, penalties, and interest into a single payment amount. These offers are typically generated by the Treasurer’s office or through the tax sale process and are case-specific. Settlement offers can reduce the total balance, pause further penalty accrual, and remove a parcel from the tax sale list, but owners should review the terms carefully before accepting.

• Payoff quote – written amount good for a specific date
• Settlement offer – consolidates multiple years of delinquency
• Penalty freeze – stops further accrual upon acceptance
• Tax sale removal – protects the parcel from auction
• Recorded release – clears the lien from public record

Kendall County Property Tax Certification Requirements

Tax certifications are written documents issued by the Treasurer’s office that confirm the current tax status of a parcel.

• Closing certification – confirms a clear tax status at sale
• Refinance certification – required by most lenders
• Title search certification – supports legal research
• Tax sale status – confirms whether the parcel is on the sale list
• Special assessments – lists pending non-tax levies
