The Mechanics Behind Section 280E
280E shuts off ordinary Section 162 business expense deductions for a trafficking trade or business, but Congress cannot reach cost of goods sold without violating the constitutional definition of gross income. COGS survives because it is a subtraction on the way to gross income, not a deduction from it — and every workable New Mexico cannabis tax strategy is built on that narrow distinction.
In practice, a New Mexico dispensary or producer loses federal deductibility on marketing, most administrative salaries, delivery costs and retail floor rent, while costs that qualify as inventoriable under Sections 471 and 263A survive intact. Operators who address this only at tax time discover the damage after the books are already closed; operators who build their chart of accounts around it capture every dollar the law allows.
- Section 162 deductions: disallowed for the plant-touching business
- Cost of goods sold: preserved, governed by Sections 471 and 263A
- Tax credits: generally unavailable alongside disallowed deductions
- State treatment: New Mexico's income tax does not mirror the federal disallowance
A COGS Methodology That Holds Up in Examination
The IRS has repeatedly challenged operators who relabel selling costs as inventory. Champ, Olive, Patients Mutual (Harborside) and the line of cases that follow them all draw the same boundary: a reseller's COGS stops at invoice cost plus the expense of getting product in the door, while a producer may capitalize a much broader set of production costs.
That boundary shapes how we build the books for every New Mexico license type. Retail licensees operate under a narrow COGS ceiling. Producer and vertically integrated license holders capitalize direct materials, direct labor and defined indirect production costs into inventory, releasing them to COGS as product moves off the shelf. We put the methodology in writing, tie it to the general ledger, and preserve the workpapers behind each allocation.
Retail License Positions
For a retail-only license in Albuquerque, Santa Fe or anywhere else in the state, we capture invoice cost, inbound freight, and the narrow set of acquisition costs the reseller rules permit. Any non-plant-touching function is separated with its own books, its own agreements and real personnel time records — not a label applied after the fact.
Producer License Positions
Producer, microbusiness and vertically integrated license holders capitalize direct materials, direct labor and allocable indirect production costs. Cultivation utilities, nutrient and media costs, cultivation payroll, grow-room depreciation and in-process testing typically qualify. We build a costing model tied to plant-count-limited production output and revalue inventory at each period close.
Planning Continuously, Not Scrambling in April
A 280E position is set by how costs are coded during the year, not by anything a preparer does after year end. We segregate inventoriable and non-inventoriable cost at the point of entry, review the effective tax rate every quarter, and forecast estimated payments against real gross margin instead of a stale safe harbor.
The two costliest mistakes we see across New Mexico operators are underfunding federal estimated payments while cannabis excise tax obligations pull cash the other direction, and taking aggressive cost positions with no paper trail behind them. Both are inexpensive to prevent and expensive to fix after the fact.
- Quarterly effective-rate and cash-tax forecasting
- Reasonable compensation and distribution review
- Entity analysis wherever a genuinely separate trade or business exists
- Written methodology memos kept in the permanent tax file
Substantiation and Audit Readiness
Plan for examination as a certainty, not a possibility. Cannabis returns draw disproportionate attention because of the size of the potential disallowance and the cash-heavy nature of the business, and the taxpayer carries the burden of proving inventory cost.
We keep a standing audit file year-round: inventory valuation tied to BioTrack package activity, labor allocation studies backed by time records, function-based depreciation schedules, intercompany agreements, and the memoranda that explain each significant position. When a notice arrives, the response file already exists.
How New Mexico's Own Tax Rules Interact
New Mexico's corporate and personal income tax does not adopt the federal 280E disallowance for licensed cannabis activity, so ordinary and necessary expenses that are lost federally are generally still deductible on the state return. That produces a permanent book-to-tax gap and a state return that bears little resemblance to the federal one.
That gap has planning value. Because state-level deductibility diverges sharply from the federal computation, it changes the after-tax math on compensation planning, lease decisions and whether a function belongs in its own entity.
What 280E Costs a Real New Mexico Operator
Consider an Albuquerque storefront retailer with $6,000,000 of gross receipts, a 48 percent product margin and $2,300,000 of operating expenses. Gross profit is roughly $2,880,000 and book pre-tax income is roughly $580,000. Federally, almost none of the $2,300,000 is deductible, so the tax base is gross profit rather than income. The result is a federal liability calculated on nearly five times the economic profit, and an effective rate that would be absurd in any other industry.
Now move the same operator to a producer license. A mixed-light cultivator near Las Cruces with the same revenue capitalizes cultivation payroll, nutrients, power, water, grow-room depreciation and quality assurance into inventory. The disallowed pool shrinks to sales, marketing and general administration, and the effective rate falls dramatically. Nothing about the underlying economics changed — only the license type and the quality of the cost accounting behind it.
This is why we start every 280E engagement with a modeled comparison of current-state and properly-costed federal liability. The gap is usually large enough to fund the entire accounting function several times over, and it's quantified before any work is done.
Case Law That Shapes Every Position We Take
CHAMP established that a taxpayer can operate a separate, non-trafficking trade or business alongside a cannabis business and deduct the expenses of that separate business. It also set the standard: genuine separateness, supported by real allocation of employee time, space and expense. Olive narrowed the practical scope by rejecting a claimed second business that was in substance a way to give away services to cannabis customers.
Patients Mutual, the Harborside case, closed the door on retailers dressing selling expenses as inventory cost and confirmed that a reseller's COGS is governed by the reseller rules. Subsequent decisions reinforced that 263A doesn't expand a trafficker's inventoriable costs beyond what 471 already permits for that taxpayer type.
The through-line is that structure and documentation win cases, and creative recharacterization loses them. We take positions we can trace to a specific inventory rule, and we write down why, at the time — not in response to an information document request.
- CHAMP: separate trade or business is possible, with real economic separation
- Olive: form without substance fails
- Patients Mutual: resellers cannot inventory selling costs
- Consistency across years matters as much as the position itself
