Shoppers were generally supposed to pay the sales tax to the state themselves, but most didn't, says Gerald Storch, who was CEO of department store operator Hudson's Bay and now runs his own retail consulting firm.
The ruling is a victory for states that said they were losing billions of dollars in revenue every year, and for large retailers that had argued that the physical presence rule meant they were playing by different rules than online-only sellers. Small businesses may face headaches complying with various state sales tax laws, though there are software options to help.
