Illinois sales tax rates
Counties, cities, transit districts and home-rule municipalities add their own rates, so the combined rate on general merchandise ranges widely across the state.
Sales tax is charged at the rate for the place where the buyer takes delivery, so a business that ships within Illinois charges the rate at the customer's address.
How to calculate it
Sales tax = price × combined rate. At 8.75%, a $1,000 sale carries $87.50 of tax and the customer pays $1,087.50.
To take the tax out of a tax-included total, divide by one plus the rate: $108.75 ÷ 1.0875 = $100.00. Subtracting 8.75% of the total instead gives the wrong answer, because the rate applies to the pre-tax price.
What is not taxed in Illinois
Qualifying groceries, prescription and nonprescription medicine and medical appliances are taxed at a reduced rate instead of 6.25%. The state's own 1% grocery tax ended on January 1, 2026, but many cities and counties now charge their own 1%.
Rates and exemptions change, so confirm the rate for a specific address with the Illinois Department of Revenue before you file. This calculator does the arithmetic; it is not tax advice.
