Illinois requires you to either keep track and report what you owe OR calculate an "assumed" number based on a percentage of your income.
The line is titled "Use tax on internet, mail order or other out of state purchases" The form specifically says, "Do not leave blank."
The implication is that you HAVE purchased something. If you're a little old lady who only buys at the local grocery store, I don't know what they expect you to do. Maybe you put in a dollar.!
