Hi I read you have to get an EIN to collect sales taxes if you have a nexus in an American state. When you send your products to Amazon FBA you have a nexus in the state the warehouse is. So are you really charged by the government to pay those taxes even if you already pay them in your own country? It doesn't seem fair to be taxed twice. Is there a way to avoid this situation? Do you know how much.money there taxes represent ?
