2023 PAY 2024 TAXES



The Warren County Treasurer’s Office, Warren County Animal Control & Warren County Board is pleased to announce our new dog registration program for Warren County.  The new program will allow Warren County residents to register their dogs online, if they so choose to do so. 


Residents can still come into the Treasurer’s Office or utilize mail options and register their dog.  This has been a work in progress migrating from our old system to the new system as Warren County has over 4,000 dogs.  We felt that this was a step in the right direction to make it easier for residents to be able to give an additional option to register their dogs.  


To view our new dog registration website please visit:  



Once you have entered the website, simply click on the My Account tab which will open options to login, create an account or if you contact our office, we can provide you with a quick account setup code for a quicker way to create an account.  Once an account has been created you will automatically see that your information as well as your dog information has been inputted into the system. 


If you are a new pet owner and have not registered with us, you will have to input your pet’s information.  Once you are logged in within the my account tab, you will be able to view your pets information, upload rabies certificates, upload photos, view/print rabies tag information, report your pet lost and several other options.  

This program will also allow you to purchase a rabies tag (as long as we approve the rabies certificate you upload) and you will be able to pay online (convenience fee will apply) and we will mail you your tag.   

Additional tabs with information that you will see on our website include Animal Control Ordinances, Animal Control information, WIAR (Western IL Animal Rescue) information and Freedom Ride Animal Rescue information. Tabs for adoptable pets and stray pets will be available in the near future.   

Please be on the look-out for reminder letters as well as late notices as we are working very hard to get everything updated.  In the future, we will also be able to send out notices via email.  As we transition from old to new, please be patient if you experience any issues and please contact us with any questions or problems.

Payment may be made in the form of cash, check, debit/credit card, or the drop box located on the east side of the courthouse. A convenience fee does apply when using a debit or credit card. Payments may also be made by phone with a debit/credit card IF we have the dog’s Rabies Certificate in our office. If paying over the phone or mailing a check, we

The Warren County Treasurer’s office is responsible for collecting dog registrations, fees, and other related payments in accordance with the Warren County Animal Control office.

Per Ordinance 06-10-11 Animal Control Section 4 – Altered (fixed) Dogs, at the time of the second registration, any unaltered dog, whether male or female and with or without permanent identification, shall be assessed a $30.00 fee.  Any person purchasing a subsequent alteration fee after the anniversary date shall pay a late fee.   This fee shall be assessed yearly and will be paid in addition to other applicable fees.  Any altered or confined dogs shall be exempt from this fee.  If surgery poses a serious health risk to a dog due to a pre-existing medical condition, a medical exemption may be granted and obtained from a veterinarian.  Every owner must present or mail two copies of the Warren County Rabies Certificate to the Warren County Treasurer’s office with a veterinarian’s signature verifying permanent alteration at the time of registration.

Animal Control Ordinance Violation Tickets

If you have received a letter please contact the Treasurer’s Office within thirty (30) days.  Due to Warren County Ordinance# 06-10-11 Section 6 – Enforcement (b) Failure to purchase a rabies inoculation tag within 30 days of vaccination and within 30 days of the anniversary date each year thereafter shall result in a citation being issued by the Animal Control Warden.  If you receive a Warren County ordinance violation, please be advised that you will not be able to pay your citation in our office until we have proof of vaccination and you are current on your dog tags.  Please do not rely on your vet’s office to give us proof of vaccination. 

Steps Of A Dog Violation

Warren County Animal Control will issue a ticket including a court date.  If you do not take care of the ticket with the Warren County Treasurer’s office (have to have proof of current rabies vaccination and pay the ticket) before the court date, you have to SHOW UP IN COURT.

If you miss that court date, the Warren County Circuit Clerk will issue a summons, along with any associated fees, to the Warren County Sheriff whereby a Sheriff’s Deputy will serve you.  Once served, you will still need to pay the ticket with the Treasurer (have to have proof of current rabies vaccination and pay the ticket) and APPEAR on the court date of the summons.

If you FAIL TO APPEAR in court once SUMMONED, you may be found in DEFAULT (guilty) which will result in a fine and court costs payable to the Warren County Circuit Clerk.

You may submit your written request by mail, fax, email or in person. If sending your request via email, use FOIA in the subject line to identify your emails as a FOIA request and to reduce the possibility of it being filtered as SPAM.

2. Please be as specific as possible when describing the records you are seeking. Remember, FOIA is designed to allow you to inspect or receive copies of records. It is not designed to require a public body to answer questions. To the extent that you wish to ask questions of a representative of Warren County, please refer to the department list below.

Freedom of Information Act (FOIA) Overview
The purpose of the Freedom of Information Act is to ensure that all persons are entitled to full and complete information regarding the affairs of government, and the official acts and policies of those who represent them as public officials.
The principle mandate of the Act provides that each public body shall make available to any person for inspection, or upon submission of a written request, to provide copies of any requested records that are subject to disclosure under the Act. Not all records are subject to disclosure, and the Act provides a number of exemptions.
This Act is not intended to be used to violate individual privacy, nor for the purpose of furthering a commercial enterprise, or to disrupt the duly-undertaken work of any public body independent of the fulfillment of any of the rights of the people to access to information (5 ILCS 140/1). 

Response Time On FOIA Requests
All written requests shall be responded to within five (5) working days (5 ILCS/140/3) following the date the request is received, except in the instance when the request is for commercial purposes. (Within 21 working days of receiving a request for commercial purposes Warren County will: (1) provide a reasonable estimate of time needed to comply with the request along with an estimate of the fees which the requestor will be charged; (2) deny the request pursuant to a statutory exemption; (3) notify the requestor if the request is unduly burdensome and allow the requestor to revise the request to manageable proportions; or (4) provide the requested records). The five (5) day count begins the day after the receipt of the FOIA request by the Department Head or designated department FOIA officer. The requester may be notified of a five (5) day extension (working days) if the files are voluminous, at different locations, or if other reasons make it impossible to assemble and mail the request out within the normal five (5) day period. 

Denial of FOIA Requests
All county employees are encouraged to provide available information when requested by the public. Information provided or denied under the FOIA, however, must conform to the legal requirements under the Act. Certain documents may be exempt from disclosure pursuant to specific sections in the Freedom of Information Act (5 ILCS 140/3(g);7;7.5).
When a public body denies a request for public records, that body must, within five (5) working days, or within any extended compliance period provided for in the Act, notify the person who made the request, by letter, of the decision to deny the request. The letter must explain the reasons for the denial, and give the names and titles of all persons responsible for the denial.

Appeal of Denial of FOIA Requests
Any person denied access to inspect or copy any public record for any reason may appeal the denial by sending a written notice of appeal to the Public Access Counselor at the following address:
Public Access Counselor
Office of the Attorney General
500 S. 2nd Street
Springfield, Illinois 62706
