NOTICE:

 

Due to the COVID-19 outbreak the Warren County Courthouse is closed to the public unless prior arrangements have been made.  Our office is still open to assist you over the phone and by email during our regular hours shown above however our staff may be limited and reply's may take longer then normal.  Since we will not be accepting any homestead exemption applications or renewals in person until further notice they can be mailed to us or put in an envelope marked to our office's attention and left in the drop box outside the east door.  Any forms turned in that are not complete will be mailed back to you along with a letter explaining what still needs to be done.  We are also working on expanding the information available on the two websites listed below for accessing assessment data and mapping files.

Assesssment information can be found at:  https://il1374.cichosting.com/atasportal/ 
Map data is at:  https://warrenco-094.maps.arcgis.com/apps/webappviewer/index.html?id=ab19af089b1549f58ea5af6a35d73d81
See below for information on using these two sites.  Thank  you for your understanding during these challenging times.

 

Assessment and Ownership Information

 

Assessment Data and current property ownership information is currently only available by phone and email. The information may now also been seen at https://il1374.cichosting.com/atasportal/  This web portal contains general information only and does not include property record cards.  There is now a GIS option to view aerial photography available through the web portal however the only information that appears when a parcel is selected is the parcel number, site address, owners name, brief legal description and total acreage if available.  Additional information is available by clicking on the 3 dots in the lower right hand corner of the pop up box and selecting view attribute table.  Copies of property record cards and parcel maps may be obtained from our office and will be sent by regular mail along with an invoice to the address you provide when you make your request.

To go directly to the Tax Parcel App to view parcels on an aerial without going through the data portal use https://warrenco-094.maps.arcgis.com/apps/webappviewer/index.html?id=ab19af089b1549f58ea5af6a35d73d81  The dates of the aerials used at the various viewing levels is not known but might be as old as 2007.  To search on this site you must have the Owners name, Site Address or Map number which is the 10 digit parcel number without dashes.

Requests for custom reports must be made in writing detailing the information and format you are requesting.  Once the cost of the report is determined payment must be made in advance.  Click here for the current fee schedule.

Things to know when using the web portal:

 

When you are doing inquires the Tax Year is the same as the Assessment Year.  For example, if you are wanting to see what the assessment or exemptions were for 2017 payable in 2018 you will need to inquire on Tax Year 2017.  NOTE:  Assessments shown online at the Clerk, DOR (Department of Revenue) or Treas (Treasurer) levels are after adjustments have been made for various exemptions applied at the time property taxes are calculated and are not changes to the actual assessed value of the property.

If you are doing a search by address the direction is a single letter, N, S, E or W but the system does not require you to include if it is a street (ST) or avenue (AVE).  Your chances of getting results are better if you stop after the street name especially if you are not sure which it is or how it is abbreviated.  If you have a parcel number from a property record card do not enter the 94 since that is the county number and does not appear anywhere in the system.  Parcel Numbers have to be entered with dashes (XX-XXX-XXX-XX) or can be entered in the Alternate Parcel Number field without (XXXXXXXXXX).  Please note, if you are doing an inquiry by parcel number on the GIS site you have to use the alternate parcel.
