This monthly report (Exhibit 4B) is mailed separately at the beginning of every month to the Authorized Agent. This report provides a rolling three-month listing of the employer’s account: previous balance, cash receipts, advices, and ending balance. Use this account balance report to verify IMRF payments. Contact IMRF if there are any discrepancies.
This report is updated monthly. On the last line, the balance in the account is reported. Employers must pay any balance due via First Data Government Solutions Electronic Funds Transfer (EFT) system, either pay by phone or pay online.
If an employer mails IMRF its wage detail on Form 3.11, you can apply any credit balances to the next month’s deposit by including them in Section 2 of Form 3.10, ”IMRF Monthly Deposit Summary” (Exhibit 4C)
