A specific taxpayer’s return information is confidential. You may, however, access sales tax data reported by types of businesses within certain Standard Industrial Classification (SIC) Codes. This report is divided into 10 category groupings based on the type of business, such as “general merchandise,” “food,” or ""apparel"". The amount of sales tax collected in a specific incorporated municipality or the unincorporated area of a specific county is listed for each category grouping under the tax type column.
By law, all information received by the Illinois Department of Revenue (IDOR) from sales tax returns is confidential. However, Illinois law does allow a local government to receive certain confidential information, by request, provided the proper forms and agreements are completed by the local government or, in some instances, by the individual retail business. For more information, see the Confidentiality of Sales Tax webpage.
