Preguntas Frecuentes
What is the Illinois sales tax rate?
Illinois state base is 6.25% on general merchandise. With local additions, combined rates range from about 6.25% to 10.25%. Chicago is the highest at ~10.25% (6.25% state + 1.75% Cook County + 1.75% city + 0.5% RTA).
Is food taxed in Illinois?
Yes, but at a reduced rate. Qualifying food, drugs, and medical appliances are taxed at 1% state rate (not 6.25%) plus local additions. In Chicago, grocery tax is about 1-3% total. Prepared food and restaurant meals are taxed at the full combined rate.
Why is Chicago sales tax so high?
Chicago stacks four layers: 6.25% state, 1.75% Cook County, 1.75% city of Chicago, and 0.5% RTA transit. This makes ~10.25%, one of the highest of any US city.
Is clothing taxed in Illinois?
Yes. Clothing is fully taxable at the combined rate in Illinois. Unlike New York and Pennsylvania, Illinois has no clothing exemption.
What about the Cook County suburbs?
Suburban Cook County locations typically pay ~9-10% because they include state and county taxes but not the Chicago city tax. Collar counties (DuPage, Lake, Will, Kane) are lower at 7-8.5%.
Does Illinois have a use tax?
Yes. If you purchase taxable items from out of state (online or in person) and the seller does not collect Illinois tax, you owe use tax at the same rate as sales tax. It is self-reported on your IL income tax return.
Are there any sales tax holidays in Illinois?
Illinois does not currently have a regular annual sales tax holiday like Texas or Florida. However, the state has occasionally enacted temporary tax relief measures on groceries and school supplies through specific legislation.
