Rescheduling tax scenarios

Where things stand in September 2026

Two facts frame every scenario.

First, the order published on 28 April 2026 put FDA-approved marijuana products and marijuana subject to a state medical marijuana license in Schedule III. Because section 280E reaches only Schedule I and II substances, that activity is outside it going forward. Treasury and the IRS announced a transition rule under which the change generally first applies for the full taxable year that includes the order’s effective date, and said mixed businesses will apportion expenses. The detailed guidance had not been published as of mid-September 2026.

Second, adult-use marijuana is still Schedule I. The DEA hearing on broader rescheduling began 29 June and ended in mid-July 2026. The administrative law judge had not issued a recommendation by mid-September, the DEA Administrator is not bound by it, and any final rule is likely to be challenged in court. The procedural detail is on the rescheduling status page.

Scenario table

Scenario	What happens	Federal income tax effect	Who it matters to
A. Current law continues	Medical in Schedule III, adult-use in Schedule I	Medical activity deducts ordinary expenses; adult-use stays under 280E; dual operators apportion	Everyone; this is the base case to price on
B. Adult-use moves to Schedule III	A final rule reschedules remaining marijuana and takes effect	280E stops applying to adult-use from the applicable tax year; credits are no longer barred by 280E	Adult-use and dual operators; retail gains most
C. Delay, stay or reversal	No final rule, or a court stays or vacates one; the April 2026 order itself could also be challenged	Adult-use stays under 280E; in the worst case medical relief is interrupted	Anyone who paid for scenario B in advance
D. Past-year relief	Refunds or abatement for years before rescheduling	None on current evidence; the IRS rejects these claims	Operators carrying large unpaid or disputed 280E balances

Nothing in scenarios A to C changes interstate commerce rules, state excise taxes, or SBA ineligibility. This page is about income tax only.

Worked example across the scenarios

Illustrative only. One retailer, C corporation, 21% federal rate, state tax ignored: revenue $4,000,000, cost of goods sold $2,200,000, operating expenses $1,200,000, pre-tax profit $600,000. Assume 30% of sales are medical and expenses are apportioned by revenue.

	Adult-use only, scenario A	Dual license, scenario A	Scenario B
Gross profit	$1,800,000	$1,800,000	$1,800,000
Deductible operating expenses	$0	$360,000	$1,200,000
Taxable income	$1,800,000	$1,440,000	$600,000
Federal tax	$378,000	$302,400	$126,000
After-tax cash	$222,000	$297,600	$474,000
Effective rate on profit	63%	50.4%	21%

Scenario B more than doubles this store’s after-tax cash, from $222,000 to $474,000. That is why the prospect of it moves prices, and why a buyer should be careful about paying for it before it exists. The apportionment driver also matters: if the same store’s medical share were 30% of revenue but 20% of transactions, the deductible amount would fall to $240,000 and tax would rise to $327,600. You can test your own numbers in the rescheduling impact calculator.

The benefit is uneven across license types because the 280E burden is. Retailers and delivery operators gain most, cultivators least; see 280E by license type.

The refund-claim controversy

Several operators have not waited. Some filed amended returns claiming 280E never properly applied to them; others file current returns on that position and book the unpaid difference as an uncertain tax liability.

• Trulieve reported in early 2024 that it had received $113 million in refunds after filing amended returns.
• In June 2024 the IRS responded that taxpayers filing amended returns to recover 280E tax are not entitled to refunds and that the claims “are not valid”.
• On 6 March 2026 the IRS filed what Foley Hoag describes as its first substantive brief defending 280E against these arguments, in New Mexico Top Organics v. Commissioner in the Tax Court.
• In May 2026 the Justice Department sued TerrAscend in the District of New Jersey to recover a refund paid in June 2024 on an amended 2020 return that claimed $64.2 million of deductions. The amount sought is about $8.36 million plus interest. In September 2026 TerrAscend moved to dismiss on procedural grounds.

For a deal, the point is simple. A refund received is not necessarily a refund kept, and a return filed without 280E creates a liability that grows with interest and possible penalties until a court or the IRS resolves it. If a target has taken these positions, the amounts, the legal opinion and the open years belong in diligence, and the exposure belongs in the tax indemnity and holdback.

What rescheduling does not fix

• Back taxes. Assessed and unpaid 280E liabilities, payment plans and liens for earlier years remain. See selling with tax delinquency.
• Open audit years. Years before the transition year are examined under the law in force then.
• Basis and inventory history. Cost of goods sold methods used in earlier years still determine opening inventory and can be challenged.
• Non-tax constraints. Banking, financing and interstate limits have their own rules; see cannabis banking status.

State conformity

Most state income taxes begin with federal taxable income. Where that is so, federal relief for medical activity flows into the state base without state legislation. States that already decoupled from 280E were letting licensees subtract the disallowed expenses anyway, so for them the change is mostly a smaller adjustment. The adult-use operator in a state that has not decoupled is the one still paying on inflated income at both levels. Some states fix their conformity to the federal code at a past date or define the subtraction narrowly, so confirm the position state by state; the statutes are in state 280E decoupling.

Using the scenarios in a deal

1. Price on scenario A. Show scenario B as upside, separately, with its own probability and timing. The valuation mechanics are in how rescheduling would affect valuation.
2. Document the medical share. For dual licensees, the quality of patient-sale records now has a direct tax value.
3. Decide who carries timing risk. A seller who believes scenario B is close can take part of the price as a contingent payment tied to it; a buyer who disagrees pays less up front. The owner’s side of that choice is in selling before or after rescheduling.
4. Define the trigger precisely. “Rescheduling” is not one date. Publication, effective date, any court stay and the first tax year to which IRS guidance applies can all differ.
5. Keep scenario D at zero. Do not pay for refunds of past-year tax.
