Unraveling the Complexity of Illinois Sales Tax

Sales tax in Illinois is a vital revenue source for the state government, municipalities, and special tax districts. The tax is applied to the sale or rental of tangible personal property and certain services.

State Sales Tax Rate
As of [Current Year], the statewide sales tax rate in Illinois stands at 6.25%. This base rate is applied uniformly across the state and is a significant contributor to Illinois’ annual revenue.
Local Sales Tax Rates
In addition to the state sales tax, Illinois allows counties, municipalities, and special tax districts to levy their own sales taxes. These local rates can vary significantly, with some areas imposing rates as low as 0% and others as high as 3.75% or more. For instance, Chicago’s total sales tax rate is 10.25%, including the state and local components.
