The state sales tax on both medical and retail marijuana is 2.9% in the state of Colorado. Retail marijuana sales are then taxed at an additional rate of 10% called a special sales tax, while medical sales are not charged this rate. In addition to these, some cities and municipalities may charge a tax on marijuana as well.
Well the retail and medical sales tax is 2.9%, special sales tax is 10% and excise tax is 15%There might be differences. I can’t really tell you more because I don’t know if you are asking for taxes as if you want to sell or tax as if you would like to buy a larger amount (we are speaking medical purposes) from Colorado and transport it somewhere else.
