Cannabis
Specialized compliance for a complex industry
Since the April 2026 rescheduling of state-licensed medical cannabis to Schedule III, operators holding both medical and adult-use licences run two federal tax regimes at once. Adult-use remains under IRC 280E, where cost of goods sold allocation is the only lever that matters. We handle that allocation, the activity-level split between regimes, and the multi-state compliance underneath both.
Technology

From startup stage to expansion, we help technology companies with reporting, R&D credits, tax planning, and scalable financial operations.
Life Sciences
Navigating complex accounting for biotech and pharma
Navigating complex accounting standards from revenue recognition to divestitures, we offer timely and pragmatic solutions for life sciences companies.

Clients choose GreenGrowth CPAs for accuracy, clarity, and long-term advisory support.
"Great team of highly qualified professionals dedicated to outstanding customer service. In an industry that can be somewhat like the wild west due to its lack of maturity and evolving standards, it was refreshing to work with a team that does things by the book where others may cut corners. If peace of mind is important to you, your employees, and the future of your business, I recommend the team at GreenGrowth."
David Spence"GreenGrowth CPAs knock it out of the park with their service. They provide loads of knowledge and practice to streamline your business. They are always willing to meet and discuss any issues or even help with a game plan on how to approach different verticals within the industry. Any time I bring new people on board, they are impressed with the quality and information that GreenGrowth brings to the table."
Austin Caby"Their attention to detail and holistic approach has made them a high-quality firm for a reasonable price. They have been key in helping us develop our cannabis business and also an accounting infrastructure where our former firm had failed. Derek (the founder) has so much experience with non-profit work that he is also good communicating with not only multiple members of the team, but also board members at their level of accounting expertise. We will gladly endorse them for their good work."
