What IRC Section 280E Actually Says and Why It Matters for Every Dispensary
IRC Section 280E is a single sentence enacted in 1982 after a drug dealer named Jeffrey Edmondson successfully deducted business expenses on his tax return: "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."
The impact of that sentence on cannabis retailers is enormous. A typical retail business deducts rent, payroll, marketing, insurance, utilities, and dozens of other operating expenses from its gross income before calculating taxable income. A dispensary cannot deduct any of those expenses if they are classified as ordinary business deductions. Consider a dispensary generating $3 million in annual revenue with $1.2 million in direct product costs and $1.4 million in operating expenses. Under normal tax rules, taxable income would be $400,000. Under 280E, those $1.4 million in operating expenses vanish from the tax equation, and taxable income balloons to $1.8 million. At a combined federal and state effective rate of 40%, the difference is $560,000 in additional tax.
The one exception is cost of goods sold. COGS is not technically a "deduction" under the tax code; it is a reduction of gross receipts to arrive at gross income. The IRS acknowledged this distinction in the legislative history of 280E and in subsequent guidance, and it is the foundation of every 280E tax strategy for dispensaries. The question is not whether you can reduce your tax burden through COGS. The question is how much of your operating costs can legitimately be reclassified from disallowed deductions to inventory costs captured in COGS.
What Clearly Qualifies as COGS for a Cannabis Retailer
The starting point is straightforward. The direct cost of cannabis products purchased for resale is unambiguously COGS. If you purchase an ounce of flower from a distributor for $100 and sell it for $250, the $100 is COGS. This includes the product cost itself, any excise tax paid on acquisition in states where the distributor passes this through, and inbound freight or delivery charges from the distributor to your facility.
For dispensaries that also process or package products, such as pre-roll operations or in-house edible production, the direct materials and direct labor involved in that production are also clearly COGS. The flower, rolling papers, and cones used in pre-roll production are direct materials. The labor hours spent by employees grinding flower, filling cones, and sealing packaging are direct production labor. These costs are COGS under any reasonable interpretation of inventory accounting rules.
Where most dispensaries fall short is stopping here. They report only the direct product purchase price as COGS and treat everything else as an operating expense, which under 280E means it is permanently disallowed. This conservative approach leaves significant tax savings on the table.
Where the Real Tax Savings Live: Indirect Costs Allocable to Inventory
The real tax savings come from allocating indirect costs into inventory under IRC Section 471, which governs how businesses value their inventory and allows certain indirect costs to be capitalized as part of inventory cost rather than expensed as period costs. Under the full absorption method described in Treasury Regulation 1.471-11, a reseller may include in inventory cost certain indirect expenses that are incident to and necessary for the purchase, storage, handling, and disposition of merchandise.
Rent for inventory storage and handling areas is the most significant indirect cost for most dispensaries. If your dispensary has a vault, stockroom, or receiving area dedicated to inventory, the rent attributable to that square footage can be included in COGS. The calculation is straightforward: measure the total leasable square footage of your dispensary, measure the square footage dedicated to inventory functions, and calculate the ratio. A 2,000 square foot dispensary with a 400 square foot vault and a 200 square foot receiving and stockroom area dedicates 30% of its space to inventory functions. If annual rent is $120,000, then $36,000 is allocable to COGS. That $36,000 reduces taxable income by $36,000, saving approximately $14,400 in tax at a 40% combined rate.
Utilities for inventory areas follow the same proportional allocation. The electricity, HVAC, and security systems protecting your inventory storage areas are allocable. Using the 30% space ratio from above applied to $24,000 in annual utilities yields $7,200 allocable to COGS.
Labor directly tied to inventory handling is the largest and most scrutinized indirect cost category. Budtenders and other staff who receive deliveries, count inventory, label products, stock display cases, conduct inventory audits, and process returns into METRC are performing inventory-related functions. The portion of their time spent on these activities, as opposed to customer-facing sales activities like greeting customers, explaining product features, processing sales transactions, and providing consumption guidance, can be allocated to COGS.
This is where documentation becomes absolutely critical. The IRS will not accept a blanket statement that "50% of budtender time is inventory handling." You need contemporaneous time studies, written job descriptions that delineate inventory functions from sales functions, and activity logs maintained in real time. A well-documented time study across a representative two-week period might show that budtenders spend 30% to 40% of their time on inventory-related activities. For a dispensary with $400,000 in annual budtender compensation, that allocation moves $120,000 to $160,000 from disallowed operating expenses into COGS.
Quality control and compliance testing costs are allocable because the product cannot be sold without passing these tests. State-mandated potency testing, contaminant screening, and label compliance verification are costs of bringing inventory to a saleable condition. If your dispensary pays $30,000 annually for compliance testing, the full amount is a reasonable COGS inclusion.
Security costs attributable to inventory protection are allocable to the extent they relate to protecting inventory rather than general business security. If your vault has a dedicated alarm system, cameras covering the inventory receiving area, and armed guards present during deliveries, those costs can be allocated. A dispensary spending $60,000 annually on security might reasonably allocate 40% to 50% to inventory protection, yielding $24,000 to $30,000 in additional COGS.
What Does Not Qualify Regardless of How Creative the Approach
Certain costs are clearly not allocable to COGS, regardless of how aggressively you structure the argument. Marketing and advertising expenses, including social media, billboard, and event sponsorship costs, have no connection to inventory acquisition or handling. General and administrative salaries for owners, general managers, HR, and accounting staff are not inventory functions. Customer-facing sales labor, specifically the portion of budtender time spent helping customers choose products and processing sales transactions, is a selling expense rather than an inventory cost. General business insurance that does not specifically cover inventory, point-of-sale system costs that facilitate sales rather than inventory management, and professional fees for legal counsel, accounting, and consulting are all non-allocable.
Attempting to classify these costs as COGS creates audit risk that far exceeds the potential tax savings. An IRS examiner who identifies clearly non-allocable costs included in COGS will not only disallow those costs but will scrutinize every other COGS line item with heightened skepticism.
The CHAMP Decision and When a Dual-Business Strategy Works
In CHAMP v. Commissioner (2012), the Tax Court ruled that a medical cannabis dispensary that also provided caregiving services could deduct expenses attributable to the caregiving, non-trafficking portion of its business. This case established the principle that cannabis businesses with legitimate non-trafficking activities can segregate those activities and deduct associated expenses normally.
For dispensaries, the practical application is narrow but worth exploring under the right circumstances. If your dispensary operates a legitimate, separately identifiable non-cannabis activity, such as a wellness consulting service, educational programming with its own revenue model, or a retail operation selling non-cannabis products like accessories and wellness items, the expenses directly attributable to that non-trafficking activity may be deductible under normal tax rules.
The key requirements established by CHAMP and subsequent case law are demanding. The non-trafficking activity must be a separate and distinct trade or business, not merely ancillary to cannabis sales. It must have its own independent revenue stream, its own identifiable cost structure, and its own business purpose that would justify the activity even if the cannabis operation did not exist. A dispensary that sells $500,000 in cannabis and $15,000 in branded t-shirts does not have a separate apparel business. A dispensary that operates a genuine wellness center generating $200,000 in non-cannabis service revenue with dedicated staff, a separate treatment area, and its own marketing might have a viable dual-business argument.
The IRS scrutinizes these arrangements heavily. A poorly structured dual-business strategy that does not survive audit will result in the disallowance of all claimed deductions for the non-trafficking activity, potential penalties for a frivolous filing position, and increased scrutiny of the COGS allocation. Do not attempt this structure without experienced cannabis tax counsel.
How to Build a Defensible Allocation Methodology Step by Step
Mapping and Measuring Your Physical Space
Create a dimensioned floor plan that identifies every area of your dispensary by primary function. Categories should include sales floor, customer waiting area, inventory vault, stockroom, receiving area, processing or packaging area, administrative offices, break rooms, security monitoring room, and common areas such as hallways and restrooms. Measure each area precisely and document the measurements with photographs and a dated floor plan.
Common areas should be allocated based on the relative use by inventory functions versus non-inventory functions. A hallway connecting the receiving dock to the vault serves an inventory function. A hallway connecting the break room to the office does not. Restrooms should be allocated based on the relative headcount of inventory-function employees versus non-inventory employees during operating hours.
The resulting floor plan should produce a clear percentage split. A typical dispensary finds that 20% to 35% of its total space is dedicated to inventory functions, though this varies significantly based on facility design. Dispensaries with large vault rooms and dedicated receiving areas will be at the higher end. Dispensaries operating in compact retail spaces will be at the lower end.
Conducting Quarterly Time Studies That Hold Up to IRS Scrutiny
For each employee role, document the percentage of time spent on inventory-related activities versus non-inventory activities. Conduct these studies quarterly and maintain the results in your permanent records. A single time study conducted in January is not sufficient to support a full-year allocation if your operations change seasonally.
For budtenders, build the time study from the actual flow of work during a shift. A typical eight-hour budtender shift might include 45 minutes of opening procedures that include inventory counting and display stocking, 30 minutes of receiving and processing a delivery with METRC data entry, 4 hours of customer-facing sales, 1 hour of restocking shelves and rotating product, 30 minutes of end-of-day inventory reconciliation, and 1 hour and 15 minutes of breaks, cleanup, and non-productive time. In this example, approximately 2 hours and 45 minutes out of 6 hours and 45 minutes of productive time is inventory-related, yielding an allocation of 40.7%. Applied across two budtenders earning $45,000 each, that moves $36,630 per year into COGS.
For compliance and receiving staff who spend the majority of their time on inventory functions, the allocation percentage will be higher, often 70% to 90%. For managers who split time between inventory oversight and general operations, the percentage may be 15% to 30%.
Calculating and Applying Your Allocation Percentages
Using your space measurements and time studies, calculate the percentage of each indirect cost category allocable to COGS. Be conservative and methodical. An overly aggressive allocation that does not survive audit scrutiny is worse than a moderate allocation the IRS accepts without challenge.
Once established, apply your methodology consistently from period to period. Changing your allocation methodology mid-year, or making significant changes between years without a documented operational reason, raises red flags with the IRS and suggests that you are manipulating the allocation to achieve a desired tax outcome rather than following a principled accounting methodology. If your dispensary renovates and the vault size increases from 400 square feet to 600 square feet, document the renovation, update the floor plan, and adjust the space allocation accordingly. That is a legitimate change. Simply increasing the allocation percentage from 20% to 30% without any operational change is not.
Documentation That Survives an IRS Audit of a Cannabis Dispensary
The IRS has audited hundreds of cannabis businesses since state-level legalization began, and 280E is their primary focus area. Cannabis businesses are audited at rates estimated to be five to ten times higher than non-cannabis businesses in the same revenue range. The auditors are not looking at your top-line revenue; they are drilling into your COGS calculation and challenging every allocation.
Maintain contemporaneous records. Records created at the time the cost was incurred are exponentially more credible than records reconstructed after the fact. Time sheets filled out daily, floor plans dated and signed at the time of measurement, utility bills with contemporaneous allocation notations, and purchase orders matched to receiving logs and METRC entries should all be maintained in real time. An IRS examiner who sees a comprehensive file of contemporaneous records will approach the audit very differently than one who sees a stack of spreadsheets created two weeks before the audit started.
Keep your METRC records reconciled with your financial records. Your track-and-trace data should match your inventory records, which should match your COGS calculation. Any discrepancy between METRC and your financial records, such as inventory quantities that do not tie or product costs that do not reconcile to purchase invoices, will be interpreted unfavorably. A 3% discrepancy between METRC inventory and your financial inventory balance, even if caused by innocent timing differences, gives the auditor reason to question the reliability of your entire COGS calculation.
Preserve a written methodology memo. Write a memo explaining your COGS allocation methodology, the basis for each allocation percentage, and the supporting documentation for each allocation. Update this memo annually. When an auditor asks how you calculated COGS, you want to hand them a clear, professional 10 to 15 page document rather than scrambling to reconstruct your logic from scattered files. This memo should reference specific exhibits: the floor plan, the time study results, the utility allocation worksheets, and the security cost breakdown.
Engage a 280E-experienced tax advisor. General tax preparers who are not experienced with 280E will either be too aggressive, leading to audit adjustments and substantial accuracy penalties under IRC Section 6662, or too conservative, leaving significant tax savings on the table. The 280E landscape has been shaped by a specific body of Tax Court cases including CHAMP, Olive, Harborside, and Patients Mutual, and your tax advisor should be fluent in all of them. The cost of specialized advice, typically $10,000 to $25,000 for a dispensary-level engagement, is a fraction of the annual tax impact.
The Financial Impact: A Worked Example with Real Dollar Numbers
Consider a dispensary with $3,000,000 in annual revenue, $1,200,000 in direct product costs, and $1,400,000 in operating expenses consisting of rent, payroll, utilities, insurance, security, marketing, and professional fees.
Without 280E optimization: The dispensary reports $1,200,000 in COGS and $1,800,000 in gross income. None of the $1,400,000 in operating expenses are deductible. Taxable income is $1,800,000. At a combined federal and state rate of 40%, the tax bill is $720,000. The dispensary's after-tax cash flow from the $3,000,000 in revenue is $3,000,000 minus $1,200,000 in product costs, minus $1,400,000 in operating expenses, minus $720,000 in taxes, leaving negative $320,000. The business is cash-flow negative despite generating $1.8 million in gross income.
With proper COGS allocation: After allocating eligible indirect costs, the picture changes. Rent allocation at 30% of $144,000 total rent adds $43,200 to COGS. Utility allocation at 30% of $36,000 adds $10,800. Inventory-handling labor at 35% of $480,000 in total budtender and receiving staff compensation adds $168,000. Security allocation at 45% of $60,000 adds $27,000. Compliance testing of $30,000 is fully allocable. Packaging and processing labor of $21,000 is fully allocable. The total indirect cost allocation is $300,000. COGS increases from $1,200,000 to $1,500,000, and remaining operating expenses decrease from $1,400,000 to $1,100,000 (though those remaining expenses are still disallowed). Gross income drops to $1,500,000. At the same 40% combined rate, the tax bill drops to $600,000.
That is a $120,000 annual tax savings from nothing more than proper cost allocation with documented support. Over five years, that is $600,000 in cash preserved in the business. And this example uses conservative allocation percentages. Dispensaries with larger inventory areas, more employees dedicated to inventory functions, or in-house pre-roll or processing operations routinely see savings of $140,000 to $200,000 annually on similar revenue levels.
How to Prepare for Potential Federal Cannabis Reform
The potential rescheduling of cannabis from Schedule I to Schedule III under the Controlled Substances Act would effectively eliminate 280E for the cannabis industry, since Section 280E applies only to Schedule I and II substances. The DEA's proposed rescheduling rule, published in 2024, set this process in motion, but implementation timelines remain uncertain and legal challenges are ongoing.
If rescheduling is enacted, dispensaries will need to transition their accounting from a 280E framework to a standard retail accounting framework. The COGS allocation methodology that was designed to maximize inventory cost inclusion will need to be replaced by standard inventory costing that separates product costs from operating expenses in the traditional manner. This transition will require restating interim-period financials, recalculating quarterly estimated tax payments, and potentially amending prior-year returns if the effective date is retroactive.
Until rescheduling is enacted into law and takes effect, dispensaries should continue to operate under the current 280E rules with full documentation and defensible allocations. Do not anticipate a change that has not yet happened. Instead, maintain clean financial records under both frameworks, a 280E-compliant set for current filing purposes and a standard retail accounting set for internal management, so that you can transition smoothly without missing a beat or leaving money on the table in the interim.
