Reduced Rate Items
Special Illinois Sales Tax Rules
1% Reduced Rate
Unlike most states that fully exempt groceries and prescription drugs, Illinois applies a reduced 1% sales tax rate to these items instead.
What qualifies for 1% rate: Food not prepared for immediate consumption (grocery store items), qualifying prescription drugs, and medical appliances.
Excluded from reduced rate: Hot foods, alcoholic beverages, candy, soft drinks, and prepared restaurant meals pay the full rate.
Why 1% Instead of Exempt?
Illinois chose to tax essentials at a low rate rather than fully exempt them, helping maintain state revenue while still providing relief compared to the full 6.250% rate.
Complex Local Tax Structure
Illinois has one of the most complex local tax structures in the nation
- • Municipal Tax: Cities can impose their own sales tax (e.g., Chicago's 1.25%)
- • County Tax: Counties add their own rate (e.g., Cook County's 1.75%)
- • RTA Tax: Regional Transportation Authority adds 1% in Cook, DuPage, Kane, Lake, McHenry, and Will counties
- • Business Districts: Some cities like Joliet have special business districts with additional 1% tax
