Breakdown
Illinois's statewide base rate is 6.25% and its average combined state + local rate is 8.96% (pre-filled). The rate is editable because local rates vary by exact address and some items are exempt or taxed differently. Statewide rates are from the Tax Foundation, 2026. An estimate, not tax advice.
A 6.25% base with heavy metro stacking
Illinois sets a 6.25% statewide rate, but county and municipal taxes push the average combined rate to 8.96% — an average local add-on near 2.7 percentage points. Chicago's combined total ranks among the highest of any major U.S. city, well above the statewide average.
Because the local layer is so large in the metro area, the 6.25% pre-fill understates what most urban purchases are taxed at. Enter the combined rate for your city or county; qualifying food and drugs may be taxed at a reduced rate. This is an estimate, not tax advice.
