Mason County, Illinois

Where to obtain records

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

How to find the information

The Treasurer page separately links Property Tax Search, online payment and Tax Settlement Sheets. At review time it showed Tax Sale: date not set yet. Use the account-search route or contact Treasury for the existing unpaid ledger or delinquency publication, and confirm the current Clerk route for taxes already sold.

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 Mason 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.
