Illinois Unclaimed Property Overview

Illinois holds millions of dollars in unclaimed property waiting to be returned to rightful owners. The Land of Lincoln holds billions in unclaimed property through its I-Cash program, including forgotten 401(k) accounts, vendor payments, and securities dividends. The Illinois State Treasurer is responsible for safeguarding and returning these assets to their owners.

Illinois uses the KAPS (Kelmar) for its unclaimed property database. Property typically becomes dormant after 3 years of no owner activity, at which point holders must report it to the state by May 1 each year.
