How do I update my business registration information or discontinue my business?
Most general maintenance can be completed electronically using MyTax Illinois which allows you to update legal and mailing address information, responsible party, owners/officers and members/managers (for Limited Liability Companies), contact information, and cease tax accounts. MyTax Illinois also allows users to add and cease sites for sales and use taxes, automobile rental tax, hotel tax, and telecommunications tax. To do so, access the Summary screen at the account level and select "View more account options," and "Maintain Locations" under the "Account Maintenance" panel. You may also complete form REG-3-C, Business Information Update, and mail or fax it to us. For any other updates, you may contact Central Registration at 217 785-3707, or you may email us at REV.CRD@illinois.gov. Please include your Illinois Account ID or License Number, business name, effective dates (if applicable), and a detailed description of the type of maintenance you are requesting.
Note: Our system allows for a corporate legal address, site address (Illinois locations only), general mailing address, and tax-specific mailing addresses, so you must be specific in the type of address you need changed.
To discontinue a business, most account types currently in MyTax Illinois can be closed electronically. You may also call Central Registration at 217 785-3707 or email us at REV.CRD@Illinois.gov.
