Cannabis MSOs' Collective 280E Tax Liability Grows to $1.6 Billion

Key Takeaway

Five major cannabis multistate operators collectively accumulated approximately $1.6 billion in potential Section 280E tax exposure through amended return claims challenging the statute's application. The strategy was based on legal theories that 280E should not apply following rescheduling discussions or does not apply to certain operational structures. The IRS began aggressively pushing back, with the agency's tax attorneys warning publicly that past taxes paid under 280E are unlikely to be refunded and that the refund claims face significant legal obstacles. For cannabis CPAs and operators, the $1.6 billion figure illustrated both the enormous tax burden 280E had imposed and the uncertain outlook for recovering any of it through litigation.
