Illinois-specific FAQs
Chicago layers four jurisdictions on top of each other: 6.25% Illinois state + 1.75% Cook County (HHST) + 1.25% city of Chicago + 1.00% Regional Transportation Authority (RTA) surcharge. The total of 10.25% applies to most general retail purchases inside city limits. Restaurant meals add another 0.50% for the Metropolitan Pier and Exposition Authority, reaching 10.75%.
Illinois historically charged a reduced 1% state rate on qualifying groceries and prescription drugs. Public Act 103-0781 eliminated the 1% state grocery tax effective January 1, 2026, but the law also lets municipalities adopt their own local 1% grocery tax β so a Chicago grocery receipt may still show 1%, while a small downstate town with no local levy is now 0%. Prescription drugs remain taxed at 1% statewide. Restaurant meals are taxed at the full combined rate.
Yes. Under the Leveling the Playing Field for Illinois Retail Act (2021), remote sellers with $100K+ in Illinois sales OR 200+ separate transactions per year must collect Illinois ROT/UT at the destination rate. Marketplace facilitators (Amazon, Etsy, eBay) collect on behalf of their third-party sellers regardless of seller size, so most online shoppers see Illinois sales tax automatically applied at checkout.
