Privacy Policy

Illinois Department of Revenue Privacy Policy

The Illinois Department of Revenue ("the Department") is committed to protecting the privacy rights of Illinois taxpayers. These rights are ensured through the various Revenue Acts, the Illinois Administrative Code, and the Department's policies and practices.

Privacy Statement

No information you provide to us on any tax return or schedule or pursuant to any tax related investigation will be disclosed except in accordance with the confidentiality provisions of the tax for which your return or schedule is filed. Disclosure of confidential tax information by the Department is strictly prohibited except as provided by the tax laws of this State.

Information you provide us in response to surveys or as email may become public records and therefore subject to disclosure under the Illinois Freedom of Information Act. It is therefore the policy of the Department that no personal information you provide to us in response to surveys or as email, including your name, address, telephone number, drivers license number, Social Security number, and email address will be sold, or rented to any entity or individual.


We will not collect personal information about you just because you visit this web site.

In order to improve the usefulness of this site for our visitors, we automatically collect and maintain statistical information from our site's data logs that concern network flow and volume. This information consists of the following:

·         the name of the domain from which the visitor accesses the internet (e.g. "a"; "a"; or "an");

·         the internet protocol address and port numbers; and

·         the date and time the IDOR web site is visited.

We routinely analyze our web site logs to continually improve the value of the materials available on our site. Our web site logs are not personally identifiable, and we make no attempt to link them with the individuals that browse these web pages. So that these web pages remain available to you and other visitors, we monitor network traffic to identify unauthorized attempts to upload or change information or otherwise cause damage to the web service. Use of this system constitutes consent to such monitoring and auditing.

Unauthorized attempts to upload information and/or change information on this web site are strictly prohibited and subject to prosecution under the Computer Fraud and Abuse Act of 1986 and Title 18 U.S.C. Sec. 1001 and 1003.

We do make limited use of cookies (a cookie is a file placed on a visitor's hard drive that allows the web site to monitor the individual's use of the site.) The cookie is ONLY used to maintain the application state during TAX FILING and is discarded at the end of the application session. If the session remains inactive for too long, the session and the cookie are disabled.

We use these web pages as a public service to provide information pertaining to the Department, its policies, educational materials, tax forms that can be downloaded, and programs. You may use these web pages to obtain information, to correspond with us, and to file your tax returns.

These web pages offer you the opportunity to electronically file your tax returns. If you use these web pages to file a tax return, you should be aware that information received by the Department of Revenue from returns filed under the Illinois Income Tax Act and the Retailer's Occupation Tax Act (as well as most other Revenue Acts) is confidential. Accordingly, we will not disclose your tax return and investigation information except pursuant to specific statutory provisions and only for official purposes. If you wish to get a copy of a form you have submitted through this web site, you must complete and submit Form IL-4506.

We protect the confidentiality of tax return information you provide us electronically just as much or more than we protect similar information you provide in paper format. (Please note however that the Department accepts no responsibility for loss of privacy during transmission "across the Internet.")

These web pages may also offer you an opportunity to ask questions, request information, or provide comment. Use of this option is voluntary and may require an email address. If during your visit to these web pages you participate in a survey or send an email, the following additional information will be collected: 1) Email correspondence: The email address and contents of the email; 2) Surveys: Any information you volunteered in response to a survey. (The information collected is not limited to text characters and may include audio, video, and graphic information formats that you have provided.) We use your email to respond appropriately. This may be to respond to you, to address issues you identify, to further improve our web site, or to forward the email to another agency for appropriate action. Survey information is used for the purpose designated.

The Department has links to other web sites including links to web sites operated by other government agencies, nonprofit organizations and private businesses. When you link to another site, you are no longer on a site covered by this Privacy Notice and you are subject to the privacy policy of that new site. 

Legal Notices

Access to the Illinois Department of Revenue ("the Department") web pages is provided subject to the following terms and conditions. Please read these terms carefully as use of these pages constitutes acceptance of all of the following terms and conditions:

Persons Under 13 Years of Age

The Department is committed to complying fully with the Children's Online Privacy Protection Act. Accordingly, if you are under the age of 13, you are not authorized to provide the Department with personally identifying information, and we will not use any such information in our database or other data collection activities. We appreciate your cooperation with this federally mandated requirement.

Personal Information and Choice

Information received by the Department from tax returns or from tax related investigations is not considered personal information and is discussed separately in the "IDOR Web Privacy Policy". "Personal information" is information about you that readily identifies you. Personal information includes personal identifiers such as your name, address, phone number, driver's license number and social security number. A domain name or Internet Protocol address is not considered personal information.

We collect no personal information about you unless you voluntarily participate in an activity that asks for information (e.g., sending an email or participating in a survey). If you choose not to participate in these activities, your choice will in no way affect your ability to use any other feature of these web pages or any other State of Illinois web site. If personal information is requested on this web site or volunteered by the user, state law and the federal Privacy Act of 1974 may protect it. However, this information is a public record once you provide it, and may be subject to public inspection and copying if not protected by federal or state law. Users are cautioned that the collection of personal information requested from or volunteered by children on-line or by email will be treated the same as information given by an adult and may be subject to public access. Again, information received by the Department from tax returns or from tax related investigations is not personal information and is accorded far greater privacy than personal information. For additional information please see "IDOR Web Privacy Policy".

This disclaimer of liability applies to any damages or injury, including but not limited to those caused by any failure of performance, error, omission, interruption, deletion, defect, delay in operation or transmission, computer virus, communication line failure, theft or destruction or unauthorized access to, alteration of, or use of record, whether for breach of contract, tortious behavior, negligence or under any other cause of action.
