Why am I being charge sales tax?

I haven’t been charged sales tax in the past. Why am I seeing this charge now? The laws around charging sales tax for products have changed. Due to a recent Supreme Court Decision, we must charge sales tax in your state. Heavy Duty Pros will collect sales/use tax only for invoices generated on and after October 1st 2018. All invoices from prior periods will not be affected.
