Trust me, when commercial truck and trailer plates are purchased they are done so in order to avoid higher taxes.
That truck or trailer does not have to ever travel in that state of registration.
Maine and Oklahoma trl plates are
Advantageous to own.
Such as an IL. IFTA plate is less than one from IN.
Some trucking companies in FL. Buy only IL plates. Because of tax laws.
When it comes to com. For hire trucks , they pay many various taxes - sales tax is not one of those. Except at the pumps. Which is a deduction.
I don't have a dog in this fight but have noticed that people with opinions about tax avoidance or evasion fall into 3 categories.
Those that have been able to take advantage of the opportunity. (Usually self employed business owners).
Those that paid and were not aware of or able to use service. (Employees)
Those that work for the government in some form, (police, Forrest ranger, teacher, social services, DNR. Etc)
The reasons are obvious and there are always exceptions to the rule.
