Minnesotans who go online to shop will soon have to pay the same state sales tax they pay at brick & mortar retailers. The change takes effect July 1st, and is being cheered by retailers who have long complained about unfair competition. Technically, it’s not a new tax. All along, online shoppers were supposed to report and pay the sales tax themselves. But almost nobody did. But soon they won’t have a choice – at least not at big online retail sites. The Minnesota Retailers Association says that it’s a good law for the state’s retailing community.
