The Comptroller of Illinois is an elected official of the U.S. state of Illinois. He or she is responsible for maintaining the State's accounts, and for ordering payments into and out of them. The office was created by the Illinois Constitution of 1970, replacing the office of Auditor of Public Accounts.
 Current occupant and duties
The Comptroller is charged, by the terms of Section 17 of Article V of the Constitution of Illinois, with the duties of: (a) maintaining the central fiscal accounts of the state, and (b) ordering payments into and out of the funds held by the Treasurer of Illinois. In accordance with this duty, the Comptroller signs paychecks or grants approval to electronic payments made by the state to its employees and creditors.
The Comptroller is also charged, by Illinois statute, with certain additional duties. In particular, the Comptroller regulates cemeteries under the Cemetery Care Act, and is charged with the fiduciary protection of cemetery care funds used for the care and maintenance of Illinois gravesites.
The Illinois Constitution provides that the comptroller must, at the time of his or her election, be a United States citizen, at least 25 years old, and a resident of the state for at least 3 years preceding the election.
Some legislators have perceived a redundancy overlap between the offices of Comptroller and Treasurer, and have therefore proposed constitutional amendments to merge the two offices and earn administrative savings. For example, HJRCA 12, considered by the Illinois General Assembly in the 2008-2009 session, would merge the office of Comptroller into the office of Treasurer.
In 2011, the incumbent Comptroller along with the Treasurer, Dan Rutherford, introduced legislation to allow voters to decide whether the offices should be merged. The legislation was opposed by Michael Madigan, Speaker of the Illinois House of Representatives.
