Acting Attorney General Todd Blanche's final order moving medical marijuana to Schedule 3 of the Controlled Substances Act - while leaving adult-use cannabis firmly in Schedule 1 - has fractured the regulatory ground beneath the cannabis industry's feet. Operators, accountants, and attorneys who spent years anticipating a clean break from Internal Revenue Code Section 280E are now staring at a patchwork result that answers some questions and defers most of the important ones. The central tension: 280E relief is coming, but who qualifies, when does it start, and what happens to years already paid?
The 280E Problem, Briefly Put
For the uninitiated, Section 280E of the Internal Revenue Code prohibits businesses that traffic in Schedule 1 or Schedule 2 controlled substances from deducting ordinary business expenses. That means a licensed dispensary cannot deduct rent, payroll, marketing, or most operating costs the way any other retailer can. The practical effect: effective tax rates for cannabis operators have routinely reached 70 percent or higher, stripping out capital that might otherwise fund hiring, expansion, or compliance infrastructure.
The industry has long treated rescheduling as the exit ramp from that burden. The order does create one - but only a partial one, and the on-ramp conditions remain unclear.
Per the order, FDA-approved marijuana products and products operating under a state-issued medical marijuana license move to Schedule 3. Because 280E only applies to trafficking in Schedule 1 and 2 substances, operators holding qualifying medical licenses have a credible path out. The adult-use side of the market does not - not yet, not under this order.
Who Gets Relief, and When
Medical-only states have the most straightforward reading. Operators in states like Pennsylvania and Florida, where the licensing structure is medical-only, can reasonably expect 280E to no longer apply to their operations once implementation is in effect. That's meaningful. A single-store operator carrying $2 million in annual revenue who has been absorbing 280E's full weight may finally be able to cost-account like a normal business.
Dual licensees in adult-use states - the multistate operators, the vertically integrated companies running both medical and recreational programs under a single roof - are in murkier territory. The consensus forming among tax professionals is that the qualifying portion of business activity, tied specifically to the medical license, may be separable. But "may be" is doing a lot of work in that sentence. Guidance from Treasury and the IRS has not resolved how operators should treat mixed-license operations, blended inventory, shared cost centers, or shared POS infrastructure. Those answers are forthcoming. When, exactly, is not yet specified.
What Treasury's initial press release did signal: relief is expected to apply beginning with the 2026 tax year. That's the go-forward relief most practitioners predicted. What it did not address - conspicuously - is the retrospective piece.
The Retrospective Question Is the Expensive One
Here's where it gets complicated. The rescheduling order itself included language encouraging the Secretary of the Treasury to consider retrospective 280E relief for tax years in which operators held qualifying medical licenses. That's not a directive. It's an encouragement. But it gave some in the industry a reason to revisit the argument that has circulated for years: if marijuana always met the criteria for Schedule 3, then 280E never lawfully applied to medical operators. The overpayment, under that logic, was always an error.
The logic holds together. The administrative reality is far more difficult. A Whitney Economics study cited in the industry places the cumulative 280E tax burden since 2018 alone - the first year operators could use IRC Section 471(c) to partially offset their liability - at $15 billion. Publicly disclosed figures from cannabis companies suggest at least $1.6 billion in 280E taxes that operators believe they do not owe. The IRS is not positioned to absorb a refund event of that magnitude, and the agency knows it.
Which brings us to statutes of limitation. For operators hoping retrospective relief materializes, the window is narrowing fast. The general rule: a taxpayer has three years from the date of filing, or two years from the date of payment, whichever is later, to claim a refund of overpaid taxes. For operators who filed returns on time every year, the 2021 tax year is already closed. The 2022 tax year closes this year.
Operators who took protective steps - filing a protective refund claim, or taking the more aggressive step of filing an amended return - may have preserved their position. Those who did not, and whose statutes have lapsed, have lost that option regardless of how Treasury ultimately rules.
There is a narrow irony here: operators who did not timely file, or who have not yet paid, may actually retain open statutes. Not a recommendation - non-compliance carries its own serious risks - but a consequence of how the rules work.
What Operators Can Do Right Now
Waiting passively for IRS guidance is a choice with real costs. Tax counsel familiar with cannabis operations have consistently advised that preserving statute-of-limitations windows, even speculatively, costs far less than discovering later that the option is gone. Operators who have not reviewed which of their tax years remain open should do that review now, with qualified advisors who understand both cannabis licensing structures and federal tax procedure.
The dual-licensee question - how to apportion revenue, costs, and liability between medical and adult-use activities within a single operation - will eventually require a defensible methodology. The operators who build that framework before guidance arrives will be better positioned than those who reconstruct it after the fact under audit pressure. Shared POS systems, blended wholesale menus, and integrated inventory management make clean apportionment harder. That's an operational reality the IRS will not ignore.
The rescheduling order represents a genuine shift. But for most cannabis operators, 280E is not resolved - it is renegotiated, partially, with significant terms still being written.
