As states continue to introduce and expand their legalization of cannabis programs, the industry has emerged into segregated markets providing very different opportunities and risks driven by state regulations which can vary drastically.

Cannabis cultivators, manufacturers, transporters and retailers continue to be challenged by effective tax rates which are higher than in any other industry given the federal illegal nature of the activity of trafficking in a Schedule I controlled substance. The pervasive intricacies of the industry result in a challenging cannabis accounting and taxation environment. In fact, lack of adequate planning will affect your cash flow.
