The bill would create a state statute. As we know from residency restrictions, the individual counties can expand on the state rules.
Where the state has a 1000 foot SORR, some counties and cities expand theirs to 2500. While the state provides no statute to charge registrants a fee, some counties do.

What most other states have found is that the population is, for the most part, broke. To pursue someone for failing to pay a $100 fee they would have to arrest (police time), prosecute (state attorney time) and then punish (jail time) the registrant. It makes economic sense to forego the hundred bucks than to spend several thousands pursuing it. It’s not like they can charge them a penalty for failing to pay a fee… if they don’t have the $100 they certainly won’t have $500.
