Updated for 2025 with real Illinois rates, brackets, and regulations
Illinois's base state sales tax rate is 6.25%, but total rates vary dramatically by location — Chicago charges 10.25% (one of the highest in the nation), while downstate Illinois often sits at 6.25-8%. Illinois has a notable quirk: groceries and prescription drugs are taxed at a reduced 1% state rate (not exempt like in many states), though some localities add their own taxes on food. Chicago layers on additional taxes including a 9% restaurant tax, a 9% amusement tax, and a 9% 'cloud tax' on streaming services like Netflix and Spotify — making Chicago's total tax burden on entertainment significantly higher than the headline rate.

Frequently Asked Questions
What is the sales tax in Chicago, Illinois?
Chicago has a combined sales tax rate of 10.25%: 6.25% state + 1.75% city + 1.75% Cook County + 0.5% Regional Transportation Authority. This is among the highest sales tax rates of any major US city.
Are groceries taxed in Illinois?
Yes, but at a reduced 1% state rate instead of the full 6.25%. Illinois is one of the few states that taxes groceries at all — most states either exempt food or tax it at the full rate. Chicago and some localities may add additional taxes on prepared food.
What is the Chicago restaurant tax?
Chicago charges a 9% restaurant tax on food and beverages consumed at restaurants, in addition to regular sales tax. This makes the effective tax on a restaurant meal in Chicago approximately 10.25% (general sales tax) — the restaurant tax actually replaces the general rate for restaurant sales.
Does Chicago really tax streaming services?
Yes. Chicago's Amusement Tax (since 2015) imposes a 9% 'cloud tax' on streaming services including Netflix, Spotify, Hulu, and similar platforms. Chicago was the first major US city to impose such a tax, and it generated substantial controversy.
What is the sales tax rate outside Chicago in Illinois?
Downstate Illinois (outside Cook and collar counties) typically pays 6.25-7.5% depending on local municipality levies. Collar counties (DuPage, Lake, Will, Kane, McHenry) average 7.5-8.5%. Many smaller downstate cities add 1-2% on top of the state base.
