For years, the way a cannabis company allocated labor costs on payday had a direct effect on how much federal tax they owed. That's what IRC Section 280E did.
As of April 2026, that's changing. And the transition has payroll implications worth understanding.
The short answer
280E prohibited cannabis businesses from deducting ordinary business expenses — including wages — from taxable income. The only deduction available was cost of goods sold (COGS). That made labor cost tracking a tax issue, not just an HR one.
In April 2026, the DOJ rescheduled state-licensed medical cannabis to Schedule III. The U.S. Department of the Treasury (Treasury) and the IRS indicated they expect rescheduling to remove 280E for covered operators. But the transition is not clean. Prior-year filings still follow the old rules. Formal IRS guidance on the transition year is pending. Adult-use cannabis stays on Schedule I.
Section 280E has been on the books since 1982. Congress wrote it to stop drug traffickers from deducting business expenses on illegal income. However, when states started legalizing medical cannabis, state-licensed operators got caught in it too.
The rule was blunt: no deductions, no credits. The only thing a cannabis business could subtract from revenue before calculating taxable income was the cost of goods sold — the direct costs of producing whatever they sold.
COGS included production labor, cultivation costs, processing and packaging, and raw materials. But more importantly, what didn't count was everything else: rent, marketing, administrative salaries, sales staff. None of it was deductible.
Essentially, cannabis businesses were paying federal income tax on gross revenue minus production costs — which is a very different calculation than net income.
280E turned labor cost tracking into a tax survival function. Here's why.
If you could document that an employee's wages were tied to production — cultivation, processing, packaging — those wages could go into COGS. COGS reduces the income you're taxed on. Every dollar you could legitimately allocate to production was worth real money.
If you couldn't document it clearly, you couldn't claim it. And if an IRS examination disagreed with your allocations, the cost of that disagreement was significant. The IRS has historically scrutinized cannabis businesses closely, as reflected in multiple Tax Court cases under 280E.
In practice, that meant cannabis payroll operations needed:
Most generic payroll systems weren't built for this. Cannabis operators with complex payroll needs often found themselves working around their systems rather than through them.
In April 2026, Acting Attorney General Todd Blanche signed a Final Order rescheduling certain cannabis products from Schedule I to Schedule III. The order covered two categories:
Treasury and the IRS announced plans to issue guidance addressing the federal tax consequences of the order, indicating they expect rescheduling to remove 280E for covered operators. For those eligible, they expect payroll, rent, and other ordinary business expenses to be deductible — though formal guidance has not yet been issued.
That's a meaningful shift. For state-licensed medical cannabis operators, the tax math is fundamentally different going forward.
Treasury also signaled two things to watch for in forthcoming guidance:
One important distinction: adult-use and recreational cannabis is not covered. Products outside the state-licensed medical system remain on Schedule I, and 280E still applies in full for recreational operators.
The transition doesn't make documentation simpler. In some ways, it adds complexity.
Here's the picture for each operator type:
For covered operators, 280E is expected to no longer govern deductions going forward. But it will still govern your prior years. If those returns get examined, they're evaluated against the old rules — and the payroll records that supported your COGS allocations need to be there.
Your transition-year records also matter. Treasury's anticipated guidance covers the full taxable year, which means 2026 records need to reflect both the environment you were operating in and the one you're moving into. Operators with clean, function-level payroll data going into that guidance are in a different position than those who need to reconstruct records after the fact.
This is the most complex situation. 280E will apply to the adult-use portion of operations but not the medical portion. Treasury has flagged that guidance will address how expenses get apportioned between those lines.
The documentation that supports that apportionment — which labor costs belong to which activities, tracked clearly in your payroll system — is directly relevant to how that guidance applies to you.
Nothing has changed. 280E applies as it always has. The documentation requirements that governed last year govern now.
The underlying capability that 280E forced — clean, function-level, audit-ready payroll documentation — doesn't stop being useful because the tax environment is shifting. It just serves a different purpose.
