Illinois sales tax rates at a glance
How sales tax works in Illinois
Illinois has a 6.25% state rate. Chicago has one of the highest rates at 10.25% (6.25% state + 1.75% county + 1.25% city + 1% additional). Food and drugs are taxed at reduced rates.
Because local rates vary, the 8.85% figure is an average rather than a rate you will always be charged. Enter the exact rate for your city or county in the calculator when you need a precise figure — the difference between the 6.25% state floor and the local maximum is what makes Illinois sales tax awkward to estimate by hand.

A receipt totalling $108.85 at 8.85% breaks down to $100.00 before tax plus $8.85 tax.
To remove sales tax, divide the total by 1.0885 rather than subtracting 8.85% — subtracting the percentage from the gross figure gives the wrong answer.
