The 280E Tax Nightmare: Why Cannabis Companies Pay More Than Anyone
Jamie
Head Cultivator
Section 280E of the Internal Revenue Code prohibits businesses that "traffic in controlled substances" from deducting ordinary business expenses on their federal taxes. This means cannabis companies can't deduct rent, payroll, utilities, marketing, or insurance — expenses that every other legal business writes off as a matter of course.
The result: effective tax rates for cannabis companies have reached 70-80% in some cases, compared to 21% for typical corporations. It's the single largest financial burden on the legal cannabis industry, and until April 2026's Schedule III reclassification, there was no end in sight.
How 280E Actually Works #
Normal Business Taxation #
For any legal business, the math is straightforward:
Revenue - Business Expenses = Taxable Income
Taxable Income × Tax Rate = Tax Owed
A restaurant earning $1M that spends $700K on rent, staff, and supplies pays taxes on $300K.
Cannabis Business Taxation Under 280E #
Cannabis companies can only deduct Cost of Goods Sold (COGS) — the direct cost of the product itself. Everything else is non-deductible:
| Expense | Normal Business | Cannabis Business (280E) |
|---|---|---|
| Inventory/product cost | ✅ Deductible | ✅ Deductible (COGS only) |
| Rent | ✅ Deductible | ❌ Not deductible |
| Employee wages | ✅ Deductible | ❌ Not deductible (except production labor) |
| Utilities | ✅ Deductible | ❌ Not deductible |
| Marketing | ✅ Deductible | ❌ Not deductible |
| Insurance | ✅ Deductible | ❌ Not deductible |
| Legal/accounting | ✅ Deductible | ❌ Not deductible |
Practical example: A dispensary earning $2M revenue with $800K in COGS and $900K in operating expenses would normally pay taxes on $300K ($2M - $800K - $900K). Under 280E, they pay taxes on $1.2M ($2M - $800K) — because that $900K in operating expenses can't be deducted. That's 4x the taxable income.
Why 280E Exists #
Section 280E was created in 1982 after a drug dealer named Jeffrey Edmondson successfully deducted business expenses from his cocaine operation on his tax return — and a tax court agreed he was entitled to the deductions.
Congress responded by passing 280E to prevent drug traffickers from reducing their tax burden. The law was never designed for legal, state-regulated cannabis businesses. But because cannabis remained Schedule I (alongside heroin), the IRS has applied 280E to every licensed dispensary, cultivator, and processor in America.
What Schedule III Changes #
In April 2026, the DEA reclassified marijuana from Schedule I to Schedule III — but only for medical marijuana. Here's how that affects 280E:
| Scenario | 280E Status | Impact |
|---|---|---|
| Schedule I (pre-April 2026) | Fully applies to all cannabis businesses | Effective tax rates 70-80% |
| Schedule III — medical operations | 280E no longer applies | Normal deductions restored |
| Schedule III — adult-use/recreational | 280E still applies (not covered by medical reclassification) | No change |
The catch: Most Michigan operators derive the majority of their revenue from adult-use sales, not medical. So while Schedule III is progress, it doesn't fully solve the 280E problem for the industry as a whole.
How 280E Hurts Small Operators Disproportionately #
Large, vertically integrated companies can structure their businesses to maximize COGS deductions — classifying more expenses under production costs. Small dispensaries and independent cultivators have less flexibility:
- Dispensaries have minimal COGS relative to overhead — 280E hits them hardest
- Small cultivators can deduct direct growing costs but not business overhead
- Equity operators on thin margins may owe more in taxes than they earn in profit
- The illicit market pays no taxes at all — creating an absurd competitive advantage for illegal operations
FAQ: 280E and Cannabis Taxation #
Q: What is Section 280E? #
A: Section 280E of the Internal Revenue Code prevents businesses trafficking in Schedule I or II controlled substances from deducting ordinary business expenses on federal taxes. Only Cost of Goods Sold (COGS) is deductible, resulting in effective tax rates of 70-80% for cannabis companies.
Q: Why can't cannabis companies deduct business expenses? #
A: Because cannabis was classified as a Schedule I controlled substance, the IRS treats cannabis businesses as drug trafficking operations under 280E — even though they're fully licensed and legal at the state level. The law was written in 1982 to target illegal drug dealers.
Q: Does Schedule III fix the 280E problem? #
A: Partially. Schedule III reclassification removes 280E for medical marijuana operations because 280E only applies to Schedule I and II substances. However, adult-use/recreational cannabis remains subject to 280E unless further legislative action is taken.
Q: How much do cannabis companies actually pay in taxes? #
A: With 280E, state taxes, excise taxes, and local fees combined, effective tax rates for cannabis companies can reach 70-80% of net income — compared to 21% for standard corporations. Michigan's additional 24% wholesale tax makes the burden even higher.
Q: How do large cannabis companies avoid 280E impact? #
A: Large operators use vertical integration (growing, processing, and selling under one entity) to classify more expenses as COGS. They also employ creative accounting structures and dedicated tax professionals. Small operators rarely have these options.
Q: What would full descheduling do to cannabis taxes? #
A: Full federal descheduling or legalization would eliminate 280E entirely for all cannabis businesses, allowing normal business expense deductions. This single change could be worth millions in tax savings industry-wide and is considered the most impactful potential federal policy change.
Q: Does the illicit market benefit from 280E? #
A: Indirectly, yes. The illicit market pays zero taxes while legal operators face 70-80% effective rates. This tax disparity makes it harder for legal businesses to compete on price, effectively subsidizing the black market's pricing advantage.
Q: Should consumers care about 280E? #
A: Yes — 280E costs are passed to consumers through higher retail prices. Every dollar of non-deductible expense adds to the cost of your product. Tax reform would likely lower consumer prices and strengthen the legal market's competitiveness against illicit sources.
The tax code wasn't written for legal cannabis. Until it's updated, every legal operator — and every consumer — pays the price.
