One of Amazon's biggest early advantages over brick-and-mortar retailers will disappear for good next month. The company will on April 1st start collecting sales in the states of Hawaii, Idaho, Maine, and New Mexico, according to a report from CNBC. That means Amazon will collect sales tax in all 45 states that require it, ending one of the company's more drawn-out regulatory fights that the e-commerce giant had resigned itself to losing years ago. (For the record, Alaska, Delaware, Montana, New Hampshire, and Oregon do not have a state sales tax.)
