Where does Illinois mail form 941 with no paymant?

Illinois employers should mail Form 941, the Employer's Quarterly Federal Tax Return, to the appropriate address provided by the IRS based on their location. If no payment is included, the form should typically be sent to the IRS address designated for returns without payments, which is often listed in the form's instructions. For the most accurate and updated mailing address, it's recommended to refer to the official IRS website or the instructions accompanying Form 941.
