How the Illinois sales tax calculation works

Illinois's sales tax rate is 6.25%: $6.25 on a $100 sale and $62.50 on $1,000. This is the state rate only. Cities, counties and districts add locally imposed sales taxes; the MyTax Illinois Tax Rate Finder shows the rate for each address. Enter your price and any local rate to see the Illinois sales tax and the total.

  1. Start with the 6.25% state rate

    Illinois charges 6.25% on taxable sales.

  2. Add your local rate if there is one

    Cities, counties and districts add locally imposed sales taxes; the MyTax Illinois Tax Rate Finder shows the rate for each address. Enter that rate as the local tax; Illinois's revenue department lists the rate for each address.

  3. Multiply the price by the rate

    Divide 6.25% by 100 and multiply: $100 × 0.0625 = $6.25, and $250 × 0.0625 = $15.63.

  4. Add the tax to the price

    A $250 item in Illinois costs the buyer $265.63 at the state rate, before any local tax.

Worked example. A $250.00 sale in Illinois at the 6.25% state rate carries $15.63 in sales tax, for a $265.63 total. If a 1% local tax applied on top, the combined rate would be 7.25% and the Illinois buyer would pay $268.13.
