The Illinois RCG-18 form serves as a crucial document for organizations conducting charitable game events in the state. This form is not just a simple tax return; it encompasses several essential components that help ensure compliance with state regulations. First and foremost, organizations must report their gross proceeds, which include all funds received from the sale of chips, admission fees, and any other donations related to the event. Additionally, the form requires a calculation of the charitable game tax due, which is typically set at 3% of the gross proceeds. Organizations must also provide detailed information about each event, including dates, gross proceeds, and any costs incurred, such as player winnings and facility leases. Timeliness is critical, as the return must be postmarked within 30 days following the last event, or penalties may apply. Furthermore, the form includes sections for reporting any noncash prizes awarded and the costs associated with security personnel. By completing the RCG-18 accurately and on time, organizations can avoid penalties and maintain their charitable game licenses, ultimately supporting their fundraising efforts effectively.
