Charging out of state sales tax is a massive violation of the constitution and the interstate commerce clause. We can thank Amazon and Ebay for screwing the American people in so many ways. This was one way. Once they got so big, states decided that they needed to sue to collect sales tax from them. The Supreme Court ruled that if a company has a significant presence in the state, then the state can force them to pay sales tax. That's fine for the billion dollar companies, but they're hitting the small companies with it as well. I think most states are setting the threshold at $100k in sales before online companies have to start paying them sales tax. Some states are super aggressive about collecting too. It's super disappointing that the founders specifically made protections against states reaching in and taxing the citizens of other states, but our modern government completely ignores it and bastardizes the meaning of the interstate commerce clause. At the rate of inflation, $100k is gonna be pocket change all too soon.
