Section 280E of the Internal Revenue Code

What Section 280E says

The full text of IRC § 280E is short: "No deduction or credit shall be allowed for any amount paid or incurred during the taxable year in carrying on any trade or business if such trade or business (or the activities which comprise such trade or business) consists of trafficking in controlled substances (within the meaning of schedule I and II of the Controlled Substances Act) which is prohibited by Federal law or the law of any State in which such trade or business is conducted." ^[1]

In practice this means a state-legal cannabis business cannot deduct ordinary and necessary business expenses — rent, wages for non-production staff, advertising, utilities for retail space, professional fees — when calculating federal taxable income. Strong evidence ^[2]

Why it exists: the Edmondson backstory

In Edmondson v. Commissioner (1981), a convicted drug dealer successfully deducted business expenses (including a portion of his home, a scale, and packaging) against his illegal income. ^[3] Congress reacted the next year by enacting § 280E as part of the Tax Equity and Fiscal Responsibility Act of 1982, explicitly to prevent traffickers from claiming such deductions. ^[4]

The statute was written decades before any U.S. state legalized cannabis. It now applies to licensed, taxpaying, state-regulated businesses — a use case Congress did not contemplate in 1982. Strong evidence

The COGS workaround and its limits

280E disallows deductions, but the U.S. tax system computes gross income as revenue minus cost of goods sold (COGS). COGS is a subtraction from gross receipts, not a deduction, so cannabis businesses can still reduce taxable income by their COGS. ^[5]

The Tax Court has repeatedly addressed how to compute COGS for cannabis businesses. In Californians Helping to Alleviate Medical Problems (CHAMP) v. Commissioner (2007), the court allowed a dispensary that also provided caregiving services to allocate expenses between the two trades or businesses, deducting the non-trafficking portion. ^[6] In Patients Mutual Assistance Collective Corp. (Harborside) v. Commissioner (2018), the court rejected aggressive COGS allocations and confirmed cultivators generally have more room than retailers because production costs legitimately fall into inventory under IRC § 471. ^[7] Strong evidence

Bottom line: cultivators and manufacturers can capitalize more costs into inventory and recover them through COGS. Pure retailers (dispensaries) have very little they can shelter.

The practical financial impact

Because operating expenses are non-deductible, federal taxable income for a cannabis retailer is often far higher than its actual book profit. Industry analyses and reporting from outlets including Marijuana Business Daily and the Tax Foundation have documented effective federal tax rates of 40% to over 80% of net income for cannabis operators, with some unprofitable businesses still owing significant tax. ^{[8] [9]} Strong evidence

This is widely cited as a contributing factor to the financial distress of multi-state operators (MSOs), failed dispensaries, and the persistence of illicit-market competition. ^[10]

Recent developments and reform attempts

Several paths could end 280E's application to cannabis:

• Rescheduling. In May 2024 the U.S. Department of Justice published a proposed rule to move cannabis from Schedule I to Schedule III of the Controlled Substances Act, following an HHS recommendation. ^[11] Because § 280E applies only to Schedule I and II substances, rescheduling to Schedule III would, by the statute's plain text, remove cannabis businesses from its scope. Strong evidence The rulemaking is ongoing as of the last verification date and is not final.
• Descheduling or legislation. Bills such as the SAFE/SAFER Banking Act do not address 280E. Broader reforms like the MORE Act would, but none have been enacted.
• Litigation. Several operators have challenged 280E on constitutional grounds (Eighth and Sixteenth Amendments). Courts have so far rejected these challenges, including in Northern California Small Business Assistants v. Commissioner (2019). ^[12]

Some MSOs have publicly stopped paying 280E-based taxes or filed refund claims based on aggressive positions; the IRS has pushed back and reaffirmed in mid-2024 that 280E remains in effect until rescheduling is finalized. ^[13] Strong evidence

What operators actually do

Common (legal) strategies include:

• Structuring vertically integrated companies so cultivation and manufacturing entities maximize inventoriable costs under § 471.
• Separating non-trafficking trades or businesses (e.g., merchandise, consulting, real estate holding companies) into distinct entities with clean books, following the CHAMP model. ^[6]
• Using cost accounting methods that properly capitalize indirect production costs.
• Working with CPAs who specialize in cannabis tax. Sloppy COGS allocations are a known IRS audit trigger. Strong evidence

What doesn't work: simply ignoring 280E, deducting standard SG&A, or relying on state-level conformity. Many states (including California and Massachusetts) have decoupled from 280E for state tax purposes, but that does not affect federal liability. ^[14]
