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.

When I took a financial controller position at a cannabis company, without prior cannabis experience, I knew I needed an experienced team that could help me navigate the nuanced and ever-changing landscape of cannabis accounting. Withum has exceeded expectations from the start. They are knowledgeable, personable and there whenever you need them. I look forward to our interactions and never feel unsupported, which has made a new job in a new industry a seamless transition I did not expect.
