Illinois State Comptroller

What Illinois State Comptroller does

The Illinois State Comptroller is a constitutional state office, established in 1848 and currently led by Comptroller Susana A. Mendoza (elected 2016), that serves as the chief fiscal control officer for the State of Illinois. Headquartered in Springfield with a regional office in Chicago, the office maintains the state's central fiscal accounts, orders payments into and out of appropriate funds, and serves four primary constituencies: Illinois state agencies (financial reporting, accounts payable processing, payroll, vendor payments), local governments (financial oversight, Local Debt Recovery Program, reporting), Illinois taxpayers (tax refund status via Find My Refund, transparency in state spending, unclaimed property search), and state vendors/contractors (Contract Lookup, Vendor Payments, direct deposit, 1099 forms).

The office's core technology platform is the Statewide Accounting Management System (SAMS), the primary statewide accounting and payment processing system used by Illinois agencies; a modernization initiative launched July 1, 2026 introduced new warrant number prefixes and updated workflows, replacing the legacy platform. Supporting the platform is a portfolio of self-service digital portals — OpenBook (transparency portal for state financial data), Salary Database (public employee compensation), Accounts Payable Statement (real-time pending voucher dashboard), MyPayStub (electronic earnings statements for state employees), Find My Refund (tax refund tracking), and Contract Lookup — all provided at no cost to constituents. The office also operates the PLACE program for regulatory oversight of crematories, funeral homes, and cemeteries, and the Executive Inspector General (OEIG) unit for misconduct investigations.

Because it is a constitutional government office rather than a commercial enterprise, the Illinois State Comptroller does not generate revenue through fees or commercial activities. It is funded by state appropriations and is statutorily responsible for managing Illinois's fiscal operations. Credit ratings on the state's General Obligation bonds (Moody's A3, S&P A-minus, Fitch A-minus) reflect the recognized fiscal stewardship delivered by the office, including reduction of the unpaid bill backlog from a $16.7 billion peak in 2017 to under $3 billion and growth of the General Revenue Fund cash balance to $1.7 billion in FY2024 (up 55% year-over-year).
