Yes. All cigarettes used in Illinois must have an Illinois cigarette tax stamp affixed to the bottom of the cigarette package.
Note: In addition to Illinois Cigarette Use Tax, Illinois Use Tax is also owed when you make purchases from retailers (catalogs, mail order, Internet transactions, etc.) not registered with Illinois. Form ST-44, Illinois Use Tax Return, must be completed to report and pay Use Tax. Save your cigarette purchase receipt. Form ST-44 allows a credit for sales tax properly due and paid to another state.
