where do i find my PIN?
To find your Illinois PIN, you can use the following methods:
Online: Visit the IL-PIN Inquiry page on the MyTax Illinois website and enter your Social Security Number and Illinois Driver’s License/State ID or prior-year AGI.

By Phone: Call the Illinois Department of Revenue’s automated PIN inquiry system at 1-800-732-8866 and provide your Social Security Number and one of the alternative verification methods.
