How 280E Works and Who It Applies To
Section 280E was enacted originally to target illegal drug trafficking but applies broadly today to any business trafficking in a Schedule I substance, and cannabis remains Schedule I federally despite New Jersey's adult-use and medicinal programs operating fully under state law. Every CRC-licensed cultivator, manufacturer, distributor, wholesaler, and retailer in the state is subject to 280E on its federal return, with no exception for state legality.
Cost of Goods Sold Is the Primary Planning Tool
Because 280E disallows deductions but not cost of goods sold, the inventory capitalization rules under IRC 471 and 263A determine how much of your total spend can offset federal taxable income. Producers, meaning cultivators and manufacturers, can generally capitalize a broader range of production costs into inventory than resellers such as retailers and wholesalers, which is why the line between production and non-production activity within a vertically integrated operation matters so much.
- Direct materials, labor, and overhead tied to production
- Allocation methodology consistent with IRC 263A for producers
- Documentation supporting each cost's inclusion in COGS
- Separate treatment for retail versus production activities
Key Case Law Shaping 280E Positions
The Tax Court's decisions in Champ Sportswear, CHAMP, Olive v. Commissioner, and Patients Mutual Assistance Collective (Harborside) have each shaped how aggressively a cannabis business can allocate costs to inventory versus disallowed operating expense, and how courts view attempts to separate a dispensary's retail activity from ancillary non-cannabis services. We build COGS methodology with this case law in mind rather than relying on aggressive positions that have already been rejected in litigation.
Entity and Activity Separation
For vertically integrated New Jersey operators running cultivation, manufacturing, and retail under related entities, properly separating and documenting each activity's costs, and pricing intercompany transfers appropriately, materially affects the group's overall 280E exposure. This requires coordination between accounting, legal entity structure, and tax preparation rather than a single year-end adjustment.
Audit Defense Preparation
Because 280E is a frequent IRS examination target for cannabis businesses, we prepare COGS support contemporaneously, with documentation organized to withstand scrutiny rather than reconstructed after an audit notice arrives.
A worked illustration: COGS allocation under 471-11
Consider an illustrative Newark cultivator with $4,000,000 in gross cannabis revenue, $1,800,000 in direct production costs (labor tending plants, nutrients, cultivation-facility rent and utilities), and $900,000 in general overhead including sales staff, marketing and executive compensation. Because the taxpayer is a producer, it applies the full absorption rules of IRC 263A and 471-11, capitalizing not only direct costs but an allocable share of indirect production costs — facility depreciation, quality-control labor, and a portion of officer compensation tied to production oversight.
In this illustration, applying a burden rate derived from a Section 263A study might allocate an additional $350,000 of indirect costs into COGS, bringing total capitalized cost to $2,150,000. Deductible COGS of $2,150,000 against $4,000,000 revenue leaves $1,850,000 of gross income subject to 280E disallowance at the federal level — meaning the remaining $900,000 of overhead (marketing, non-production salaries, professional fees unrelated to production) is nondeductible for federal purposes even though New Jersey's decoupling under P.L. 2023, c.50 allows the full $900,000 as an ordinary and necessary business expense on the CBT and GIT returns.
This gap — deductible in Trenton, disallowed at the federal level — is the central planning variable for every New Jersey operator. The wider and more defensible the COGS allocation, the smaller the federal taxable base; the studies and time logs supporting that allocation are what withstand an examination years later.
Champ, Olive, and Patients Mutual: what the case law actually decided
Californians Helping to Alleviate Medical Problems (Champ) established that a taxpayer running two integrated trades or businesses — a dispensary and a separate caregiving service — could allocate expenses between the 280E-affected trade and the non-trafficking trade, deducting the latter in full. Few New Jersey operators can replicate this fact pattern today because CRC licensure ties retail, cultivation, and manufacturing activity tightly to the cannabis trade itself, leaving little room for a genuinely separate, non-plant-touching line of business within the same legal entity.
Olive v. Commissioner rejected a taxpayer's attempt to deduct operating expenses of a dispensary that also provided ancillary services (movies, activities, counseling) on the theory those were a separate business; the Tax Court found a single, integrated trade of dispensing cannabis and disallowed nearly all deductions beyond COGS. Patients Mutual Assistance Collective Corp. v. Commissioner (Harborside) reinforced that inventory costing under 471 and 263A is the correct — and essentially only — mechanism for reducing the 280E base, and that a taxpayer cannot use aggressive reseller-style COGS treatment when it is functionally a producer.
The throughline for New Jersey licensees: cost allocation studies must reflect actual production activity as documented in Metrc and payroll records, not a generic percentage borrowed from another operator's return. An examiner testing a COGS position under Harborside logic will ask for job descriptions, time studies, and square-footage allocations tied to the taxpayer's own facility, not industry averages.
