Marijuana Businesses Beware: Internal Revenue Code Section 280E Challenges

Update The Growing Marijuana Industry and Its Federal Tax Challenges As the marijuana industry continues to expand across the United States, traditional expectations of business operations encounter glaring discrepancies. With an estimated $23.9 billion for adult-use marijuana and $7.6 billion for medical cannabis sales reported in 2025, the market is projected to top $39.1 billion by 2029. This significant growth has been propelled by numerous states that have eased restrictions surrounding both medical and recreational marijuana use. However, despite this positive trajectory, marijuana businesses are still grappling with burdensome tax laws that stem from federal regulations. Understanding Internal Revenue Code Section 280E At the center of this issue lies Internal Revenue Code (IRC) Section 280E, which is particularly punitive for marijuana businesses. Under this provision, businesses engaged in trafficking controlled substances cannot take notable deductions or credits. This reflects the federal government’s enduring classification of marijuana as a Schedule I controlled substance under the Controlled Substances Act (CSA). It's a complex and often frustrating scenario for entrepreneurs who are navigating a legal marijuana marketplace on the state level while being shackled by federal classification. Implications of 280E on Marijuana Businesses The prohibition on deductions means that, unlike most businesses, marijuana companies must report their gross income without offsetting expenses. They cannot deduct costs that many other industries take for granted, leading to significantly higher tax liabilities. While businesses can deduct the cost of goods sold (COGS), the limitations imposed by 280E mean that effective tax rates for marijuana businesses can soar as high as 70% or more in some cases. This financial burden can hinder expansion and operational effectiveness, raising the costs of consumer products despite strong demand. Current Legislative Climate: A Potential Shift? Interestingly, discussions on reform are emerging with numerous legislative proposals aimed at altering the restrictive measures of Section 280E. These proposals primarily focus on rescheduling or descheduling marijuana and could provide tailored exceptions for marijuana businesses. There is also a growing public sentiment advocating for reform, with many citizens and politicians recognizing the imbalance in how marijuana businesses are taxed compared to other industries. Constitutional Dilemmas and Challenges Unfortunately, historical challenges against the application of Section 280E have been largely unsuccessful. Efforts to legally dispute the constitutionality of Section 280E underscore broader issues regarding the powers of Congress and states, especially when it comes to the evolving consensus around marijuana use. As advocates push for reform, the reliance on constitutional arguments raises critical questions about the future of marijuana taxation and legalization. What Lies Ahead for Cannabis Businesses? The tension between federal law and state regulations surrounding marijuana use and business operations is likely to create ongoing challenges for the industry. However, if moved forward, proposed changes to federal policies will pave the way for marijuana businesses to thrive without the crippling tax constraints imposed by Section 280E. It remains to be seen how the legal landscape will evolve as advocates remain diligent in their quest for more equitable tax treatment.
