Possible online services disruption due to Internet related outage

A worldwide technology outage is causing disruption to some State of Illinois online systems.  We are aware of this issue and are diligently working on restoration.

Sales Tax Rate Machine Readable Files - Address Specific

As part of the Leveling the Playing Field for Illinois Retail Act (Public Acts 101-31 and 101-604 ), remote retailers, marketplace facilitators, and Certified Service Providers (CSPs) are required to collect and remit state and local  sales tax on certain tangible personal property in effect at the location where the item is shipped or delivered or where the purchaser takes possession (destination-based sales tax rate). 

The following machine readable file is address specific and contains the location-specific sales tax rates for addresses in Illinois. It is a large comma delimited file (approximately 2 GB compressed and 9 GB uncompressed) generally for use by software developers and electronic transmitters. Sales tax rate changes generally occur effective January 1 or July 1 of each year. 


  • Use MyTax Illinois to look-up individual location tax rates for both origin-based or destination-based sales tax rates. 
  • If you are an Illinois business (or have a presence in Illinois), or are a software developer or electronic transmitter for Illinois businesses, and you require tax rates specific to local ordinances , see the Machine Readable Files specific to counties/municipalities.
