What 280E Actually Says
IRC Section 280E is exactly two sentences long. It states that 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 consists of trafficking in controlled substances within the meaning of Schedule I and II of the Controlled Substances Act. That is the entire statute.
The critical nuance is what 280E does not say. It does not say you cannot deduct cost of goods sold. COGS is technically a reduction to gross receipts, not a 'deduction' in the IRC Section 162 sense. This distinction, confirmed in the landmark CHAMP v. Commissioner case, is the entire foundation of cannabis tax planning.
How 280E Applies to Cannabis Operations
Every state-legal cannabis business, whether it holds a cultivation, manufacturing, distribution, or retail license, is subject to 280E at the federal level. The IRS does not care that your state issued you a license. The federal Controlled Substances Act still classifies marijuana as Schedule I, and that classification is what triggers 280E.
In practical terms, this means a cannabis retailer cannot deduct rent, marketing, payroll for budtenders, insurance, professional fees, or any other ordinary business expense. A cultivation operation cannot deduct administrative salaries, office supplies, or general liability insurance as ordinary deductions. The only offset against gross revenue is properly calculated cost of goods sold.
The effective tax rate for cannabis companies routinely exceeds 70%. We have seen operators with slim margins pay more in federal income tax than they earn in net profit. This is not a hypothetical; it is the default outcome for any cannabis company that does not engage in deliberate, well-documented 280E tax planning.
What Qualifies as Cost of Goods Sold
The IRS has stated that cannabis companies must calculate COGS using the rules that applied to inventory accounting under the pre-2018 regulations, specifically IRC Section 471 and the uniform capitalization rules under Section 263A. This is important because Section 263A requires certain indirect costs to be capitalized into inventory.
Direct Costs (Always Includable in COGS)
Direct materials include seeds, clones, nutrients, growing media, soil amendments, extraction solvents, packaging materials, and any raw inputs that become part of the finished product. Direct labor includes wages for employees whose work is directly tied to production: growers, trimmers, extraction technicians, packaging line workers, and quality control staff performing in-process testing.
Indirect Costs Under Section 263A
This is where the real tax savings live. Under the UNICAP rules, certain indirect costs must be allocated to inventory. These include facility costs attributable to production (rent, depreciation, property taxes, insurance on production space), utilities consumed in the production process (electricity for grow lights, HVAC for climate control, water for irrigation), repairs and maintenance on production equipment, and indirect labor such as production supervisors and compliance staff whose work supports manufacturing.
The allocation methodology matters enormously. A cultivation facility that is 80% canopy and 20% office space should be allocating 80% of its facility costs to COGS. But that allocation must be supported by square footage measurements, utility sub-metering data, or other reasonable allocation bases documented in writing.
Costs That Do Not Qualify
General and administrative expenses, selling expenses, marketing, executive compensation not tied to production, and any costs associated with the retail or distribution side of the business do not qualify as COGS. These are the expenses that 280E permanently disallows.
Entity Structuring Strategies
One of the most effective, and most scrutinized, approaches to mitigating 280E is entity structuring. The core concept is straightforward: separate the plant-touching activities from the non-plant-touching activities into different legal entities.
The Management Company Model
A common structure involves a plant-touching entity (the licensee) and a separate management company. The management company provides services such as accounting, human resources, marketing, legal coordination, technology, and executive management. Because the management company does not itself traffic in controlled substances, it is not subject to 280E and can deduct its ordinary business expenses.
The management company charges the plant-touching entity a management fee. This fee is not deductible by the plant-touching entity (because of 280E), but the expenses incurred by the management company in providing those services are deductible on the management company's return.
This structure must have economic substance. The management company needs real employees, a real office, and real services being rendered. The management fee must be set at arm's length, meaning it should reflect what a third party would charge for the same services. The IRS has challenged arrangements where the management company is transparently a shell designed solely to shift income.
Real Property Structuring
Another common approach involves a separate real estate holding entity that owns the facility and leases it to the plant-touching operator. Rental income to the property company is ordinary income subject to ordinary deductions (mortgage interest, property taxes, depreciation, maintenance). The lease payments from the cannabis operator are not deductible under 280E, but the property company's expenses are fully deductible against rental income.
Documentation Requirements
Documentation is not a nice-to-have in cannabis tax planning. It is a survival requirement. Every COGS allocation should be supported by contemporaneous records created at the time the costs are incurred, not reconstructed at year-end.
What to Document
Maintain detailed time studies showing what percentage of each employee's time is spent on production versus non-production activities. Keep square footage calculations with diagrams showing production space versus administrative space. Install sub-meters on electrical panels to measure utility consumption by production area versus general facility use. Retain all invoices, purchase orders, and receiving records for direct materials. Keep production logs, batch records, and METRC reports that tie inventory movements to cost inputs.
Why It Matters for Audit Defense
The IRS has dedicated resources to auditing cannabis businesses. When an audit occurs, the examiner will challenge every COGS allocation that is not supported by detailed, contemporaneous documentation. The burden of proof is on the taxpayer. If you cannot prove that a cost was properly allocable to COGS under Section 263A, the IRS will reclassify it as a disallowed deduction under 280E, and you will owe additional tax plus penalties and interest.
Real Dollar Examples
Consider a cannabis cultivation facility with $5 million in gross revenue and $3.5 million in total expenses.
Scenario 1: Poor COGS Documentation
The operator claims $1.5 million in COGS based on rough estimates, with no time studies, no square footage documentation, and no utility sub-metering. The IRS audits and reclassifies $500,000 of those costs as non-COGS expenses. Taxable income jumps from $3.5 million to $4 million. At a combined federal and state effective rate of 50%, that reclassification costs $250,000 in additional tax, plus penalties and interest.
Scenario 2: Proper COGS Allocation
The same operator engages a qualified cannabis CPA to perform a Section 263A analysis. With proper documentation, COGS increases to $2.2 million by correctly including allocable indirect costs (facility, utilities, indirect labor, depreciation). Taxable income drops to $2.8 million. The tax savings compared to Scenario 1 is $350,000 per year.
Over a five-year period, the difference between these two approaches exceeds $1.5 million in cash tax savings for a single facility. That is the real cost of ignoring 280E planning.
Common Mistakes We See
Treating 280E Like a Normal Tax Problem
Many general-practice CPAs apply standard tax logic to cannabis returns. They deduct rent, marketing, and admin costs because that is what they do for every other client. When the IRS audits and disallows those deductions, the operator is stuck with a massive tax bill plus penalties.
Failing to Separate Production and Non-Production Costs
Some operators lump all facility costs together without allocating between production and administrative space. This leaves money on the table because the production-related portion of facility costs is allocable to COGS.
Ignoring State Conformity Issues
Not every state conforms to 280E. California, for example, does not apply 280E at the state level. This means your state return may look very different from your federal return, and you need a tax advisor who understands both.
Over-Aggressive Positions Without Documentation
We have seen operators claim 90% or more of total expenses as COGS without any supporting analysis. These positions invite audit scrutiny and rarely survive examination.
The Rescheduling Question
The DEA's potential rescheduling of marijuana from Schedule I to Schedule III has generated significant attention. If rescheduling occurs, Section 280E would no longer apply because it only covers Schedule I and II substances. This would be transformative for cannabis operators.
However, rescheduling timelines are uncertain, and building your financial plan around a future legislative change is not a sound business strategy. Operators should plan as if 280E will remain in effect indefinitely while positioning to benefit if and when relief comes.
Building Your 280E Defense
The operators who survive 280E are the ones who treat tax planning as a core business function, not an afterthought. This means engaging a cannabis-specialized CPA or CFO service, performing a formal Section 263A cost study, implementing sub-metering and time-tracking systems, maintaining contemporaneous documentation, and reviewing your entity structure annually.
280E is brutal, but it is survivable. The operators who thrive under it are the ones who understand the rules deeply enough to use every legal tool available.
