What Is Section 280E?

Section 280E of the Internal Revenue Code prohibits businesses engaged in "trafficking" Schedule I or II controlled substances from claiming most ordinary business deductions. Because cannabis remains a Schedule I substance under the Controlled Substances Act, cannabis companies are generally barred from deducting rent, salaries, marketing, and other standard business expenses.

How It Works in Practice

A cannabis retailer might generate $5 million in revenue with $4 million in operating expenses. Under normal tax rules, the business would pay tax on $1 million of profit. Under 280E, however, only Cost of Goods Sold (COGS) may be offset — leaving a taxable income figure that can far exceed actual economic profit. Effective tax rates of 70–90% are not uncommon for vertically integrated operators.

The COGS Carve-Out

The one meaningful exception is that 280E does not disallow deductions allocable to Cost of Goods Sold under IRC § 471. Sophisticated operators use IRC § 471(c) (added by the Tax Cuts and Jobs Act of 2017) to expand what costs qualify as COGS, potentially capturing indirect overhead costs. Proper accounting segregation between plant-touching and non-plant-touching activities is critical.

Business Structure Implications

Many multi-state operators maintain separate legal entities for their management companies, technology platforms, and licensed dispensary or cultivation operations. This structure aims to keep non-plant-touching revenue in entities not subject to 280E. Aggressive structuring has attracted IRS scrutiny — careful documentation and defensible business-purpose rationale are essential.
