Internet giant Amazon.com will start to collect sales taxes on purchases made by Floridians starting May 1st. Amazon's entry into the state's brick-and-mortar retail landscape could mean about $80 million a year in sales taxes. The move wasn't unexpected as the company is building a pair of massive fulfillment centers in Polk and Hillsborough counties along Interstate 4. John Fleming, a spokesman for the Florida Retail Federation, said the announcement is probably a sign that Amazon will soon trigger a collection requirement by starting to hire for the year-end holidays, which for retailers begins in September. Fleming says they're going to have to have employees ready by then.
