Colorado Begins Legal Marijuana Sales, Collecting Marijuana Tax January 1, 2014 Joseph Bishop-Henchman Joseph Bishop-Henchman Courtesy Twitter user @john_ingold At 8:00 AM this morning, the world's only legal retail marijuana sales began in Colorado: At least 37 stores across the state were fully licensed and opened to sell marijuana to anyone 21 or over for any purpose, according to official lists and Denver Post research. Sales began at 8 a.m., and activists — who passed the marijuana-legalization measure in November 2012 that made the sales possible — arranged a ceremonial "first purchase" at the stroke of 8 at the Denver store 3D Cannabis. The customer was Sean Azzariti, an Iraq War veteran from Denver who was featured in pro-legalization campaign ads in which he said he hoped to use marijuana to alleviate post-traumatic stress disorder. The cost of the ceremonial first sale was $59.74. 130 retailer licenses have been issued, but not all were ready to open their doors on the first day. State officials project $67 million a year from taxes on marijuana sales. These consist of the existing 2.9 percent state sales tax (plus local taxes), an additional 10 percent state tax on retail marijuana sales, and a 15 percent excise tax on the "average market rate" of wholesale marijuana. In Denver, that means a $30 eighth of pot (1/8 oz.) will have about $8.59 in taxes tacked onto it, or about a 29 percent overall tax rate. Stay informed on the tax policies impacting you.
