Suppose I am an ecommerce platform - I don’t sell any of my own products, but am merely a conduit for other entities to sell their product to consumers. Am I still responsible for sales tax on B2C sales?
What I’m really selling in this case is the use of my platform/service to the actual B2C sellers on my platform. So my sales tax ought to be based on what said sellers pay me, and what jurisdictions they’re based in.
