Why the rate here is not the whole story
Illinois charges 6.25 percent statewide on general merchandise. Only 5 percent of that is kept by the state and 1.25 percent is passed straight through to the municipality or county where the sale is sourced, but the whole 6.25 percent is imposed by the state and every location in Illinois pays it. Municipalities, business districts and transit districts then add their own rates on boundaries that do not follow county lines, so a single rate for the whole county does not exist. The county itself levies 1.5 percent countywide. The floor of 7.75 percent is in unincorporated county. The ceiling of 8.75 percent is at Colona. These figures are general merchandise rates. Qualifying drugs and medical appliances are taxed at a lower rate that starts at 1 percent statewide, and since January 1 2026 groceries carry no state rate at all although a municipality or county may impose 1 percent of its own, so neither belongs in the range here.
