I mean, whenever the item says $69.99 on the tag for instance (I know for a fact that is not the final price) as ST exists dependent on state having their own percentages added on top. Also, why do visitors have to pay ST on both goods and services despite them not living in the US? Do tourists get reimbursed for that or not?
Why do visitors anywhere have to pay any tax? Where are you from that there’s no sales tax and no VAT?
Japan, for one, allows visitors to buy things for use outside Japan without sales tax. Well, to be clear, they refund the sales tax you paid on certain items when you leave the country.
There are a couple of US states that do something similar I believe.
