Section 280E and the Cannabis Industry: COGS Allocation Only, Schedule III Rescheduling Impact

Section 280E cannabis tax law blocks state-legal marijuana operators from deducting ordinary and necessary business expenses on their federal returns because the underlying product remains a Schedule I controlled substance. The provision was enacted in 1982 in direct response to a Tax Court decision allowing a convicted drug trafficker to deduct business expenses. The only relief available under section 280E is the cost of goods sold (COGS) recovery permitted by Reg section 1.471-3, which is treated as a basis adjustment rather than a deduction.

What is section 280E?

Section 280E of the Internal Revenue Code denies any deduction or credit for amounts paid or incurred in carrying on a trade or business that “consists of trafficking in controlled substances (within the meaning of schedule I and II of the Controlled Substances Act).” The statute is short, blunt, and contains no exception for state-legal activity. It was enacted as part of the Tax Equity and Fiscal Responsibility Act of 1982 after the Tax Court’s decision in Edmondson v. Commissioner (T.C. Memo. 1981-623), which allowed a convicted drug dealer to deduct ordinary business expenses including rent, the cost of a scale, and travel.

Marijuana has remained on Schedule I of the Controlled Substances Act since the CSA’s enactment in 1970, so section 280E applies in full to every state-legal cannabis operator. The Tax Court has consistently upheld 280E’s application to state-legal dispensaries in Californians Helping to Alleviate Medical Problems Inc. v. Commissioner (128 T.C. 173 (2007)), Olive v. Commissioner (139 T.C. 19 (2012), affirmed by the Ninth Circuit at 792 F.3d 1146), and most recently in Patients Mutual Assistance Collective Corp. v. Commissioner (151 T.C. 176 (2018)).

Why section 280E matters for cannabis operators

Section 280E creates an effective tax rate that bears no relationship to economic income. A typical dispensary may have 20% gross margin on product, then absorb rent, payroll, security, marketing, and compliance costs. The rent, payroll outside of production, marketing, and most depreciation are all nondeductible. Federal taxable income equals gross profit (revenue minus COGS) with virtually no offsets. A dispensary with $10 million in revenue, $6 million in COGS, and $3.5 million in operating expenses might have book income of $500,000 but federal taxable income of $4 million, resulting in federal tax of roughly $840,000 at the 21% corporate rate. Effective federal rate on book income: 168%.

The effect cascades into operational decisions. Cannabis operators run all-cash operations partly because of banking limitations, but also because every cost-allocation decision turns into a tax decision: is this person inventory labor (deductible via COGS) or selling labor (disallowed by 280E)? Multi-state operators (MSOs) such as Curaleaf, Trulieve, Green Thumb Industries, and Verano routinely disclose 280E-driven effective tax rates of 60%-80% in their SEC filings.

How the section 280E COGS workaround works

The only legitimate path to recover operating costs under section 280E is the cost of goods sold workaround. The Tax Court in Californians Helping to Alleviate Medical Problems (CHAMP) confirmed that section 280E does not disallow COGS because COGS is a basis adjustment to inventory under section 471, not a deduction under section 162. The IRS clarified this in CCA 201504011 (January 23, 2015), which held that cannabis sellers must use Reg section 1.471-3 (the basic inventory cost rules) rather than Reg section 1.471-11 (the broader full absorption costing rules for producers).

The producer vs. reseller distinction

A cannabis producer (cultivator, processor, or manufacturer) can capitalize a broader set of costs into inventory than a reseller (dispensary). Under Reg section 1.471-3(c), a producer can capitalize direct materials, direct labor, and a portion of indirect production costs including factory overhead, depreciation on production equipment, repairs to production facilities, indirect labor of production personnel, and utilities for production areas.

A reseller is more constrained. Under Reg section 1.471-3(b), a reseller can capitalize the invoice price of goods purchased (less trade discounts), transportation-in, and certain other costs incident to acquiring the merchandise. Rent, store-front payroll, marketing, security at the retail level, and compliance costs are not COGS for a reseller. This explains why vertically integrated cannabis operators routinely structure operations to maximize the percentage of activities classified as production.

Section 263A absorption costing is not available

The IRS in CCA 201504011 explicitly held that section 263A (the uniform capitalization rules requiring producers and resellers to capitalize a broader set of indirect costs) cannot be used to capitalize otherwise-disallowed 280E expenses into inventory. The Tax Court agreed in Patients Mutual Assistance Collective Corp. (151 T.C. 176 (2018), aff’d 995 F.3d 671 (9th Cir. 2021)). Cannabis operators may not use section 263A to capitalize otherwise-disallowed selling expenses, even though section 263A normally requires capitalization for inventory-holding businesses with average gross receipts above the small-business threshold.

Section 280E impact: dispensary vs. cultivator vs. MSO

Worked example

Green Valley Dispensary LLC is a single-state retail operation in Massachusetts taxed as a C-corporation. 2026 financial results:

• Revenue: $8,000,000
• Cost of inventory purchased from licensed cultivators: $4,800,000
• Transportation-in costs: $50,000
• Retail rent: $360,000
• Retail payroll (budtenders, security, manager): $1,200,000
• Marketing and advertising: $200,000
• Compliance and METRC tracking software: $80,000
• Depreciation on retail buildout: $90,000
• Bank fees and merchant processing: $120,000
• Total operating expenses: $2,050,000
• Book net income before tax: $1,100,000

Federal taxable income calculation:

• Gross receipts: $8,000,000
• Less: COGS (inventory + transportation-in only): $4,850,000
• Gross income: $3,150,000
• Less: deductions allowed despite 280E: $0 (no separate trade or business; all operating costs trace to the cannabis trade)
• Federal taxable income: $3,150,000
• Federal tax at 21%: $661,500

Effective federal rate on book income: $661,500 / $1,100,000 = 60.1%

Massachusetts decoupled from section 280E for state corporate tax purposes effective for tax years beginning January 1, 2022 (Chapter 24 of the Acts of 2022), so for state purposes Green Valley deducts the full $2,050,000 in operating expenses. The dispensary’s combined federal plus state effective rate is therefore moderated by the state decoupling. As of mid-2026, twenty-plus states with adult-use programs have decoupled from 280E for state income tax purposes, including New York, New Jersey, Illinois, Michigan, Colorado, California, and Washington.

Recent changes: DEA Schedule III rescheduling status

The DEA published its Notice of Proposed Rulemaking on April 30, 2024 (89 FR 38046) to reschedule marijuana from Schedule I to Schedule III of the Controlled Substances Act. The proposal followed an August 2023 recommendation from the Department of Health and Human Services based on a scientific review by the FDA. Rescheduling to Schedule III is the operative event for section 280E purposes: section 280E by its terms applies only to “schedule I and II” substances, so a Schedule III classification would end the 280E penalty regardless of any subsequent state action.

The DEA held administrative hearings on the proposed rule throughout late 2024. The administrative law judge process concluded in January 2025. As of June 2026, the final rule has not been published in the Federal Register. Industry analysts at Cantor Fitzgerald and Cowen have published research notes estimating the section 280E elimination would free $3-5 billion in annual cash flow across the publicly traded MSO sector. The market price of state-legal cannabis equity has reflected significant volatility tied to rescheduling timeline expectations. Public MSO disclosures filed on SEDAR (the Canadian filing system used by U.S.-licensed operators due to U.S. banking limitations) routinely identify section 280E as the single largest financial reporting variable, with Curaleaf, Trulieve, Green Thumb Industries, Cresco Labs, and Verano each citing rescheduling timing as a principal forward-looking risk factor in their MD&A sections.

Important caveats: rescheduling does not legalize marijuana federally, does not eliminate state-by-state licensing, and does not change banking limitations under the Bank Secrecy Act. Federal banking relief (the SAFER Banking Act) remains a separate legislative track. For forensic and compliance considerations during the transition period, see our forensic accounting coverage.

Common pitfalls

• Treating all payroll as inventory labor. The Tax Court in Patients Mutual Assistance Collective Corp. (151 T.C. 176 (2018)) rejected attempts to allocate dispensary front-of-house labor to COGS. Only labor with a direct nexus to producing or acquiring inventory qualifies under Reg section 1.471-3.
• Attempting to use section 263A absorption costing. CCA 201504011 (January 23, 2015) ruled that 263A cannot be used to capitalize otherwise-disallowed section 162 expenses into inventory. The position has been sustained in every subsequent Tax Court decision.
• Splitting “cannabis” and “non-cannabis” trades or businesses to side-step 280E. The Tax Court in Olive v. Commissioner (139 T.C. 19 (2012)) and the Ninth Circuit at 792 F.3d 1146 rejected attempts to characterize ancillary services (caregiving, education) as separate trades or businesses where the activity was integrated with cannabis sales.
• Failing to update return positions if rescheduling is finalized. When the DEA Schedule III final rule publishes, the effective date will determine the first tax year that ordinary business expense deductions are available. Cannabis operators should run multiple-scenario tax models pre-publication.
• Confusing state decoupling with federal relief. State income tax decoupling from section 280E (Massachusetts, New York, New Jersey, Illinois, and others) does not change federal treatment. Operators in decoupled states still face full 280E on their federal Form 1120.
• Skipping inventory documentation. The COGS workaround depends entirely on the operator’s ability to document the inventory cost flow. Without contemporaneous records tying labor and indirect costs to production activity, the IRS can recharacterize claimed COGS as disallowed selling expenses.
• Ignoring section 280E in transaction due diligence. Acquirers of cannabis operators must price 280E exposure into the deal, including potential successor liability for understated tax in open years (statute of limitations is six years for substantial omissions under section 6501(e)).

Frequently asked questions

Does section 280E apply to state-legal medical marijuana?

Yes. The Tax Court in Californians Helping to Alleviate Medical Problems Inc. v. Commissioner (128 T.C. 173 (2007)) confirmed that state legality has no bearing on section 280E because marijuana remains federally classified as Schedule I.

Can a cannabis operator deduct salaries paid to executives?

Only the portion of executive compensation directly traceable to production activities can be capitalized into COGS for cultivators and processors. Executive compensation for sales, marketing, and corporate functions is generally nondeductible under section 280E for the cannabis trade.

Does section 280E apply to hemp-derived CBD?

No. The 2018 Farm Bill (Agriculture Improvement Act of 2018, P.L. 115-334) removed hemp containing less than 0.3% delta-9 THC by dry weight from the Controlled Substances Act schedules. Hemp operators are not subject to section 280E and may use ordinary business expense deductions and section 263A absorption costing.

What happens if marijuana is rescheduled to Schedule III?

Section 280E by its terms applies only to Schedule I and II substances. Rescheduling to Schedule III would end section 280E’s application to marijuana, allowing ordinary business expense deductions and section 263A absorption costing. The change would be effective on the date specified in the final rule, not retroactively to prior tax years.

Are 280E penalties subject to alternative minimum tax?

The disallowed deductions increase taxable income for both regular tax and AMT purposes. There is no separate AMT adjustment that relieves 280E exposure.

Can an LLC owned by a cannabis operator avoid section 280E by electing C-corp status?

No. Section 280E applies to the trade or business activity regardless of entity classification. The choice of pass-through vs. C-corp affects who pays the tax (the entity or the owners) but does not change the underlying disallowance.

Does section 280E apply to ancillary cannabis service providers?

No, as long as the ancillary provider is not “trafficking” in controlled substances. Cannabis-adjacent businesses (software, consulting, real estate, security services) that do not take possession of or title to the controlled substance are not subject to 280E. The Tax Court in Olive confirmed the activity must consist of trafficking.

How does an IRS examination of a cannabis operator typically proceed?

The IRS Office of Chief Counsel issued ILM 201531016 (May 2015) confirming examiner authority to reclassify COGS as disallowed selling expenses. Examinations focus on labor allocation between production and sales, indirect cost allocation methodology, and contemporaneous documentation of inventory cost flow under Reg section 1.471-3.
