Automated sales suppression software — commonly called a “zapper” or “phantomware” — alters the electronic records of a point-of-sale or electronic cash register system so that sales, and the tax collected on them, go unreported. Illinois addresses this conduct through a dedicated criminal statute squarely prohibiting automated sales suppression devices.

Parallel provisions at 35 ILCS 110/15, 115/15, 120/13. Added by P.A. 98-352.

If you have received an audit notice, a reassessment, or an inquiry concerning suppression software in Illinois, the statute above is the provision most likely at issue. Confirm its current text before relying on it.
