Statement of Purpose for Collection of Social Security Numbers

 
 

What does the Illinois Department of Revenue do with your Social Security Number?

The Identity Protection Act (5 ILCS 179/1 et seq.) requires each local and State government agency to draft, approve, and implement an Identity-Protection Policy that includes a statement of the purpose or purposes for which the agency is collecting and using an individual’s Social Security number (SSN). This statement of purpose is being provided to you because you have been asked by the Illinois Department of Revenue to provide your SSN or because you requested a copy of this statement.

Why do we collect your Social Security number?

You are being asked for your SSN because the Department of Revenue needs it to administer one or more of the following laws:

  • the Illinois tax acts, including but not limited to the Illinois Income Tax Act, the Retailers’ Occupation Tax Act, the Illinois Property Tax Code, and others;
  • the Illinois Lottery Law; and
  • the Illinois Liquor Control Act.

What do we do with your Social Security number?

  • We will only use your SSN for the purpose for which it was collected.
  • We will not:
    • Sell, lease, loan, trade, or rent your SSN to a third party for any purpose;
    • Publicly post or publicly display your SSN;
    • Print your SSN on any card required for you to access our services;
    • Require you to transmit your SSN over the Internet, unless the connection is secure or your SSN is encrypted; or
    • Print your SSN on any materials that are mailed to you, unless State or Federal law requires that number to be on documents mailed to you, or unless we are confirming the accuracy of your SSN.
