They just have a system that audits business after a certain time and makes sure they pay their fees. Probably runs every morning on businesses opened a fixed time before, and there is a bureaucrat who collects the output and puts it in the mail. Other than the fees are too high, I can’t see what the problem is.
You can’t see the problem with them mailing taxes to bogus addresses?
don’t forget the mailing to the wrong address to generate more fees...
