Tazewell County GIS parcel viewer
The Tazewell County GIS Viewer (Public) provides parcel mapping and property tax reference information. The viewer includes tools such as basemaps, draw, bookmarks, parcel info, actions, tax record, print, and search.
Parcel details shown in the viewer may include a PIN, address, city and ZIP, municipality, township, total acres, legal description, and assessment information.
The GIS viewer states that parcel and map records are for property tax purposes only and should not replace a title search.
Assessment Office records and property details
The Tazewell County Assessment Office handles assessment-related property information and is led by the Supervisor of Assessments. The office provides assessment links, exemption forms, name or address change forms, split and combination request forms, township assessor information, and Board of Review appeal information.
The office explains equalization as a uniform percentage increase or decrease used to bring assessment levels to a uniform level of market value, stated as 33.33%.
For reassessment timing, Tazewell County uses a quadrennial schedule. Property is viewed, inspected, and valued once every four years, while farm acreage must be reassessed annually.
Property tax payments and parcel number use
The Tazewell County Treasurer’s payment page allows real estate tax payments online or by phone. When paying by credit card, taxpayers must enter the 12-digit Parcel Number, also called the PIN, located at the top right corner of the tax bill.
Payment fee details are listed below.
| Payment type | Fee | Notes |
|---|---|---|
| Credit or debit card | 2.25% with a $1.95 minimum | Applies to online, phone, and counter card transactions |
| E-check | $1.25 flat fee | Charged by the service provider |
| Phone payment | Service provider fees apply | Payments can be made at (309) 925-0025 |
Assessment appeals and missing or disputed details
If a property search shows information that may affect the assessed value, the Board of Review page explains the appeal path. The Board of Review hears appeals about assessed valuation, not the tax rate or the tax bill amount.
Taxpayers are advised to first contact the township or county assessing official. If the issue is not resolved and the taxpayer can support a claim, a formal appeal may be filed with the Board of Review.
Useful appeal evidence may include the property record card, photos, comparable property records, transfer documents, an appraisal, recent comparable sales, or information showing an error in the property record.
