Mercer County, Illinois

Where to obtain records

Mercer County Treasurer / Collector; County Clerk for sold-tax redemption

How to find the information

The Treasurer directs Property Tax Records research to merceril.devnetwedge.com and says online bill copies can be printed free. It specifically asks callers to obtain correct amounts after the second installment is past due. The County Clerk handles delinquent taxes after sale; request the existing ledger or a dated Clerk redemption estimate.

To obtain existing unpaid-tax records, provide the parcel/PIN, tax year, payable year and desired as-of date. Specify whether you need current collection history, the annual delinquency publication, tax-sale/certificate history or a dated redemption estimate. Ask whether subsequent taxes, interest, penalties, costs and recent payments are included. Confirm inspection, electronic-copy, research, certification and extract fees with the office. Assessor valuations, ordinary property sales, trustee-auction catalogs and payment receipts do not by themselves certify every unpaid obligation.

What to ask for

“I am looking for publicly available delinquent real-property tax records for Mercer County for [tax year]. Which office maintains these records? Is there an online search or downloadable list? If not, how can I request a copy, and what fees apply?”

Have the property address, parcel number, owner name, and tax year ready when searching for a particular property.

County-specific notes
