Rescheduling already happened, but only partly. An order effective in April 2026 moved FDA-approved cannabis drug products and cannabis held under a state medical licence from Schedule I to Schedule III. IRC Section 280E no longer applies to those qualifying medical operations.
Adult-use cannabis was not included. It remains Schedule I and remains fully subject to 280E. If you operate adult-use only, nothing about your federal tax position has changed.
Does rescheduling eliminate Section 280E? For state-licensed medical operations, yes. For adult-use, not yet. Section 280E applies only to Schedule I and Schedule II substances. Once something moves to Schedule III, the provision stops reaching it.
The April 2026 order drew that line down the middle of the industry. A medical operator has ordinary business expense deductions back. An adult-use operator does not. An operator holding both licences now runs two federal tax regimes at once, with every shared cost allocated between them and no IRS default method to fall back on.
Broader rescheduling covering adult-use remains undecided. A DEA administrative hearing ran from 29 June to 15 July 2026, the parties filed post-hearing briefs, and the DEA's own final brief argued that cannabis should move to Schedule III. The administrative law judge has not issued a recommendation and no timeline has been set.

The Line That Was Drawn
Who Got Relief, and Who Did Not.
Most coverage of rescheduling treats cannabis as one thing. The April 2026 order did not, and that distinction now decides your federal tax position.
State-licensed medical cannabis
Cannabis held under a state medical licence, and FDA-approved cannabis drug products, moved to Schedule III.
Section 280E reaches only Schedule I and Schedule II substances, so it no longer applies to those operations. Ordinary and necessary business expenses become deductible federally.
Adult-use cannabis
Adult-use was not included in the order. It remains Schedule I.
Cost of goods sold remains the only meaningful deduction, and COGS allocation remains the largest single lever on the federal bill. Nothing about that has changed.
If you read a piece saying rescheduling ended 280E for cannabis, check the date it was written. A great deal of commentary published before April 2026 anticipated a broader order than the one that arrived, and much of it has never been corrected.
Not certain which side of that line your licences fall on?For most operators it is obvious. For medical combination businesses and Registered Organizations it is not, and the answer changes the return. Ask a cannabis CPA →
The Mechanism
Why Schedule III Ends 280E.
Section 280E disallows deductions and credits for any trade or business trafficking in controlled substances listed in Schedule I or Schedule II of the Controlled Substances Act. The provision is written by schedule, not by substance name.
So the tax consequence follows the schedule automatically. Move a substance to Schedule III and 280E simply stops reaching businesses dealing in it. No separate tax legislation is required, which is why a scheduling decision made by drug enforcement agencies produces an immediate tax effect.
Schedule III substances are those with an accepted medical use and a lower potential for abuse than Schedule I or II. That framing is why the April 2026 order reached medical cannabis first: the medical-use finding is the part that fits the Schedule III definition most directly.
What deductibility actually restores
- Marketing, advertising and selling expenses
- Salaries and wages outside production
- Rent on retail and administrative space
- Professional fees, insurance and general administration
- Depreciation on non-production assets
For a qualifying medical operation, the federal effective tax rate moves toward what a comparable business in any other industry would pay. That is a material change to cash flow, and it changes what the business is worth.
The Immediate Planning Problem
Medical Operators Have a Split 2026.
This is the part most commentary still describes as hypothetical. For medical operators it is not hypothetical. It is the return you are filing.
The order took effect partway through the calendar year. For a calendar-year medical operator, that divides 2026 into two different tax environments inside a single return.
| Period | Treatment | What It Means |
|---|---|---|
| Start of the year to the effective date | 280E applies | Only cost of goods sold is deductible. Operating expenses incurred in this window are disallowed. |
| Effective date to year end | 280E does not apply | Ordinary and necessary business expenses become deductible for qualifying medical activity. |
| Consequence | Expenses must be dated | Which side of the line an expense falls on changes whether it is deductible at all. Annual totals are not sufficient. |
What that demands of the records
A general ledger that produces annual figures cannot answer this. You need expenses dated and attributable to a period, with a documented basis for the split where a cost spans both, such as an annual insurance premium or a lease.
Accrual timing matters more than usual here, as does consistency of accounting method. A business that changes its approach mid-year to improve the outcome is creating a question it will have to answer later.
Can your books split this year at a date rather than a quarter?If the answer is no, that is the work to do before year end rather than during filing season. Get the records ready →
Dual-Licence Operators
Two Federal Regimes, One Set of Costs.
An operator holding both a medical and an adult-use licence now sits under two different federal tax treatments at the same time. Medical activity is outside 280E. Adult-use activity is inside it.
That is straightforward for costs that clearly belong to one side. It is not straightforward for everything else, and most costs are everything else.
Costs that have to be allocated
- Rent and occupancy where one facility serves both
- Management and executive salaries
- Security, insurance and compliance
- Point of sale, software and technology
- Accounting, legal and professional fees
- Shared marketing and brand spend
The IRS has published no default allocation method for this situation. That means the methodology you adopt is the methodology you defend, so it needs a rational basis, consistent application, and documentation created at the time rather than reconstructed afterwards.
Square footage, revenue share, headcount and transaction volume are all defensible bases depending on the cost. What is not defensible is choosing a different basis for each cost to maximise the outcome.

Prior Years
Can You Amend Prior Returns?
No, and be wary of anyone who says otherwise.
Tax law applies according to the rules in effect during the year being filed. Cannabis sat in Schedule I during those years, so Section 280E applied to those years. A later change in schedule does not reach back and alter the law that governed a closed period.
This comes up often enough to be worth stating plainly, because the arithmetic looks tempting. An operator who paid tax on disallowed expenses for five years can calculate a large number. That number is not recoverable through amendment, and a filed claim for it invites scrutiny of everything else on the return.
Where amendment can be appropriate
There is a real distinction here. You cannot amend to claim relief that did not exist in the year. You can amend to correct the return you actually filed, for instance where cost of goods sold was allocated too conservatively under the rules that did apply. That is a different claim entirely, and it stands on its own merits.
State returns are also separate. Several states decoupled from 280E on their own timelines, and a state return filed on federal logic may have unclaimed deductions available under state law. New York City, for example, decoupled retroactively to tax year 2022.
Existing Attributes
What Happens to Existing NOLs.
Many cannabis businesses carry net operating losses generated through inventory cost capitalisation, including positions taken under Section 471(c). Those losses were computed under the law in effect at the time.
They remain valid tax attributes. Standard carryforward rules continue to apply, including the limitation under which post-2017 losses offset no more than 80 percent of taxable income in a carryforward year.
What rescheduling does not do is allow a recalculation of prior taxable income. Closed years stay governed by the law that applied to them, and the NOL carried forward is the one those years produced.
Why that matters more now, not less
A medical operator moving out of 280E may generate taxable income for the first time in years. Existing carryforwards become immediately useful against it, which makes the accuracy of those balances worth confirming before you rely on them. Loss balances that were never going to be used are often less carefully maintained than ones that were.
What Comes Next
Where Broader Rescheduling Stands.
Adult-use operators have the larger stake in what happens next, since broader rescheduling would end 280E for them too. Here is the actual state of the proceeding.
| Stage | Status |
|---|---|
| April 2026 order | Effective. FDA-approved cannabis drug products and cannabis under a state medical licence moved to Schedule III. Adult-use excluded. |
| Expedited DEA hearing | Ran 29 June to 15 July 2026 on whether cannabis more broadly should be rescheduled. |
| Post-hearing briefing | Complete. The DEA's own final brief argued that cannabis should move to Schedule III. |
| Administrative law judge | No recommendation has been issued, so there is no decision and no published timeline. |
| After any recommendation | A final rule would still need to be issued and published, and would face likely legal challenge. |
The honest position is that the direction of travel looks favourable and the timing is unknowable. Planning for the possibility is sensible. Building a budget, a covenant model or a valuation on the assumption is not. See the DEA rescheduling regulatory actions page for current status.
Adult-use only? Your 280E work has not changed.
Cost of goods sold allocation remains the largest lever on your federal bill, and it is worth revisiting rather than waiting on a decision that may not come.
Equally Important
What Rescheduling Does Not Change.
It is not legalisation
Schedule III is still a controlled substance classification. Cannabis remains federally controlled, and rescheduling is a tax and research change rather than a legal-status change.
Interstate commerce stays closed
Product still cannot move across state lines. Multi-state operators still run separate supply chains, separate entities and separate compliance in each market.
State rules are untouched
Licensing, excise tax, seed-to-sale tracking and state compliance obligations all continue exactly as before. Several states also apply their own 280E treatment independently.
Banking is largely unchanged
Financial institutions set their own risk policies. Some may become more comfortable over time, but rescheduling does not by itself resolve banking access.
Action
What to Do Now.
The work differs sharply depending on which side of the April 2026 line you sit.
If you hold a state medical licence
- Confirm your records can split the year at a date, not a quarter
- Document the basis for any cost spanning both periods
- Confirm existing NOL balances, since they may now be usable
- Revisit compensation and expense timing for the post-effective period
- Hold accounting methods consistent rather than changing them mid-year
If you hold both medical and adult-use licences
- Adopt an allocation methodology and document it now, at the time
- Use a rational basis per cost type and apply it consistently
- Build the split into the chart of accounts rather than working it out at year end
- Expect the methodology to be the first thing examined if anyone looks
If you are adult-use only
- Nothing has changed federally, so treat any planning on that basis as speculative
- Revisit cost of goods sold allocation, which remains the real lever
- Check whether your state has decoupled, since several have
- Model what normalised taxation would look like, without budgeting on it

Common Questions
Rescheduling and 280E FAQs.
What changed and for whom
Does rescheduling to Schedule III eliminate Section 280E?
For the operations it covers, yes. Section 280E applies only to businesses trafficking in Schedule I or Schedule II controlled substances, so moving to Schedule III removes them from its reach. The important qualification is scope. The April 2026 order covered FDA-approved cannabis drug products and cannabis held under a state medical licence. Adult-use cannabis was not included and remains Schedule I, so 280E continues to apply in full to adult-use operations. A blanket statement that rescheduling ended 280E for cannabis is not accurate.
Does this help adult-use cannabis operators?
Not directly, and not yet. Adult-use cannabis remains Schedule I following the April 2026 order, so IRC Section 280E still disallows ordinary business expense deductions for adult-use activity. Cost of goods sold remains the only meaningful federal deduction, which keeps COGS allocation the largest lever on the tax bill. A DEA hearing on broader rescheduling ran in mid-2026 and the DEA's own brief argued for Schedule III, but no decision has been issued and no timeline has been set.
What if we hold both a medical and an adult-use licence?
You now run two federal tax regimes at once. Medical activity sits outside 280E and adult-use activity sits inside it, so every shared cost has to be allocated between them. Rent, management salaries, security, insurance, technology and professional fees all fall into that category. The IRS has published no default allocation method, which means the methodology you adopt is the one you will defend. It needs a rational basis, consistent application, and documentation created at the time rather than reconstructed later.
Timing and prior years
What is the split year and who does it affect?
The April 2026 order took effect partway through the calendar year, so a calendar-year medical operator has two different tax environments inside one return. Expenses incurred before the effective date fall under 280E and are largely disallowed. Expenses after it are deductible for qualifying medical activity. That means expenses have to be dated and attributable to a period, with a documented basis for anything spanning both, such as an annual insurance premium or a lease. A general ledger producing only annual totals cannot answer the question.
Can we amend prior returns to recover 280E disallowed expenses?
No. Tax law applies according to the rules in effect during the year being filed, and cannabis sat in Schedule I during those years, so 280E applied to them. A later scheduling change does not reach back. Be cautious of advice suggesting otherwise, because a claim on that basis invites scrutiny of the whole return. A separate point worth distinguishing: you can amend to correct a return you actually filed, for example where cost of goods sold was allocated too conservatively under the rules that did apply. State returns are also separate, since several states decoupled from 280E on their own timelines.
What happens to net operating losses created under 280E?
They remain valid tax attributes and standard carryforward rules continue to apply, including the limit under which post-2017 losses offset no more than 80 percent of taxable income in a carryforward year. Rescheduling does not allow a recalculation of prior taxable income, so closed years stay governed by the law that applied to them. Those balances matter more now than before, because a medical operator leaving 280E may generate taxable income for the first time in years and will want to use them. Confirm the balances are accurate before relying on them.
Scope and limits
Does rescheduling legalise cannabis federally?
No. Schedule III is still a controlled substance classification, so cannabis remains federally controlled. Rescheduling changes tax treatment under Section 280E and eases certain research restrictions. It does not legalise cannabis, does not open interstate commerce, and does not override state licensing or compliance requirements. Banking access also stays a matter of individual financial institution risk policy rather than something rescheduling resolves on its own.
How long could broader rescheduling take?
There is no reliable answer, and anyone giving a confident date is guessing. The DEA held an expedited hearing on broader rescheduling from 29 June to 15 July 2026 and post-hearing briefs have been filed. The administrative law judge has not issued a recommendation. After any recommendation, a final rule would still need to be issued and published, and would face likely legal challenge. The direction of travel looks favourable and the timing is genuinely unknowable, which is why planning for the possibility makes sense while budgeting on it does not.
Should we change our accounting method to prepare?
Be careful here. Consistency of accounting method is one of the things examiners look at first, and a business that changes its approach mid-year in a way that improves the outcome has created a question it will need to answer. Legitimate method changes exist and follow a defined process. What causes problems is informal drift, where treatment quietly shifts between periods without a documented basis. Decide the approach, document why, and apply it consistently.
