How Local Sales Tax Works in Illinois
Home rule municipalities, counties and transit districts all add to the 6.25% state rate in Illinois, and Chicago sits among the highest combined rates of any large US city. Illinois splits its tax into Retailers Occupation Tax and Use Tax components, which is why the rate that applies can depend on whether the seller has an Illinois location.
Which Illinois Rate Should You Charge?
Illinois has moved steadily toward destination sourcing. Retailers shipping from outside Illinois, and since recent changes many out-of-state retailers with an Illinois presence, apply the rate in force at the delivery address. Sales made over the counter at an Illinois store are sourced to the store.
What Illinois Taxes — and What It Doesn’t
Illinois removed its 1% state tax on groceries effective 1 January 2026, but authorised local governments to impose their own grocery tax in its place — so groceries may still be taxed locally. Prescription and non-prescription medicines are taxed at a reduced rate rather than being exempt.
