It's rare to see a front page story on sales tax on the newsstand, so I had to buy a copy of the paper. The article complains about the complexity of Illinois sales tax law regarding mostly food, non-prescription drugs and equipment. They sent reporters out to buy stuff to see if the stores computed the tax correctly based on what they bought. What a surprise - the stores didn't do it correctly all the time. What's actually surprising is that they did it correctly so often.
What would be more interesting is whether or not the cashiers were making the mistake about an item's taxability, or if it was the stores' systems that were incorrectly programmed. Naturally the reporters didn't ask that question.
Anyway, for your enjoyment, here's the story.
