Illinois Statutes Chapter 40. Pensions § 5/15-168.2. Audit of employers

(a) Beginning August 1, 2013, the System may audit the employment records and payroll records of all employers. When the System audits an employer, it shall specify the exact information it requires, which may include but need not be limited to the names, titles, and earnings history of every individual receiving compensation from the employer. If an employer is audited by the System, then the employer must provide to the System all necessary documents and records within 60 calendar days after receiving notification from the System. When the System audits an employer, it shall send related correspondence by certified mail.

(b) When the System submits a request for information under subsection (a) of this Section, the employer shall respond within 60 calendar days of the System's request. Beginning on the 61st calendar day after the System's request, the System may assess a penalty of $250 per calendar day until receipt of the information by the System, with a maximum penalty of $25,000. All payments must be received by the System within one calendar year after receipt of the information by the System or one calendar year after reaching the maximum penalty of $25,000, whichever occurs earlier. If the employer fails to make complete payment within the applicable timeframe, then the System may, after giving notice to the employer, certify the delinquent amount to the State Comptroller, and the Comptroller shall thereupon deduct the certified delinquent amount from State funds payable to the employer and pay them instead to the System.
