Illinois sales tax: 6.25% general merchandise rate plus local tax, with the 1% low rate for drugs and medical appliances.
This calculator combines the 6.25% Illinois general merchandise rate under the Retailers' Occupation Tax Act (35 ILCS 120) with the local home rule, county, transit and business district taxes that stack on top, and prices qualifying drugs, medical appliances and food at their reduced rate on the same receipt. It also shows how the 6.25% is split by statute — 5.00% to the state, 1.00% to municipalities and 0.25% to counties — which is why the 'state' rate already contains a local element. Retailers, remote sellers shipping into Illinois and shoppers checking a Chicago receipt all get the same layered breakdown.

10.25% on general merchandise — the highest combined rate among large US cities. It is the 6.25% Illinois state rate plus 1.25% City of Chicago, 1.75% Cook County and 1.00% Regional Transportation Authority.
6.25% on general merchandise. That headline figure is itself divided by statute: 5.00% stays with the state, 1.00% is distributed to municipalities and 0.25% to counties, before any additional local tax is added on top.
The 1% state grocery tax was repealed with effect from 1 January 2026 under Public Act 103-0781, but the same law lets municipalities impose their own 1% grocery tax without a referendum. Whether you pay 0% or 1% on food therefore depends on your town — check its ordinance or the MyTax Illinois Tax Rate Finder.
It depends on whether delivery was separately contracted for. If the delivery charge is an inseparable part of the sale, it is taxable; if the buyer had a genuine choice — for example the option to collect the goods — and the charge is stated separately, it is not. The rule is at 86 Ill. Adm. Code 130.415; ask a tax professional if your invoices are borderline.
