Cannabis Industry Trends and Challenges

The cannabis industry operates within differing state regulatory frameworks and evolving federal guidance. Licensing requirements, product testing standards, seed-to-sale tracking mandates and tax structures may vary dramatically by jurisdiction. For multi-state operators, complexity increases as different entities in numerous states may present several structural issues that need to be addressed.

Cannabis companies face higher federal tax rates compared to traditional businesses due to IRS Section 280E restrictions. IRC Section 280E prohibits deducting ordinary business expenses while still allowing cost of goods sold deductions. Our cannabis tax planning specialists develop 280E accounting strategies that maximize allowable cost of goods sold (COGS) deductions, implement tax-advantaged entity structures, provide exit planning consulting in exits to ESOP’s and position businesses for immediate tax relief when rescheduling occurs.
