What is the relationship between retailers' occupation and use tax in Illinois?
In Illinois, there are two separate but complementary taxes upon the sale and use of tangible personal property. Section 2 of the Retailers’ Occupation Tax Act imposes a tax upon persons engaged in the business of selling tangible personal property at retail to purchasers for use or consumption. Section 3 of the Use Tax Act imposes a tax upon the privilege of using, in this state, tangible personal property that is purchased anywhere at retail from a retailer. These two taxes comprise what is commonly known as "sales tax" in Illinois. See e.g., Ji Aviation v. Ill. Dep't of Rev., 335 Ill. App. 3d 905, 914 (4th Dist. 2002).
The retailer uses its gross receipt to calculate its retailers’ occupation tax liability, and as a part of the same transaction, the retailer satisfies its statutory obligation to collect the use tax owed by the customer. In effect, this use tax collection reimburses the retailer for its retailers’ occupation tax liability. If a retailer does not collect use tax on a sale of tangible personal property to a customer who will use that property in Illinois, the customer must pay the use tax directly to the State of Illinois.
