The state of Illinois assesses a 6.25% state sales tax on the sale of retail items,  the lease/rental of most goods, and some services. Local jurisdictions (think counties) impose additional sales taxes ranging between 0.25% and 4.75%. The range of total sales tax rates within the state fluctuates between 6.25% and 11%.

Use tax is also collected on the consumption, use, or storage of goods in Illinois if sales tax was not paid on the purchased goods. The use tax rate is the same as the sales tax rate. 

Returns are to be filed on or before the 20th day of the month following the month in which the purchases were made. For example, purchases made in the month of January should be reported to the state of Illinois on or before February 20th.
