Why would they ever fix the system. Some number of people will just pay it and those people are pure profit. Heck, fixing the system costs money.

It's the same evil math behind every other billing scam that sails under the flag of ignorance.

Speaking of ignorance, to all those people saying you forgot to fill out a form, there are several states that are known to be maliciously sloppy about this sort of thing. You file a form and they silently reject it or billing you anyway on some questionable pretext because they can. NY is one of them. Doesn't surprise me that IL is too since both states are kinda cash strapped.

The system is run by employees of whatever agency handles taxes. Neither the employees nor the agency keep a portion of the taxes. If they do not have the money or will to fix it, people are supposed to pressure their representatives to give them the money and mandate.

If this truly came down to an intent to squeeze more money out of people than they owed, that would almost always come from the law's wording. Again, pressure the representatives.

The only times an agency would squeeze money is when it's funded in large part by fines or fees, or if an employee is committing fraud and pocketing some of the money.

> pressure the representatives

In the GP's case, it sounds like they were on a road show, and they do not live in Illinois at all. Of course, that doesn't prevent them from contacting a IL state representative for redress, but it is an edge case of sorts.
