IRC Section 280E: A Working Guide for Minnesota Operators
The statute, the case law that shaped it, and the accounting that determines your exposure.
Section 280E is twelve lines of statute that reshape the economics of every plant-touching cannabis business in the country. This guide explains what it does, what it does not do, and where the legitimate planning sits.
It is written for Minnesota operators, so it covers both the federal rule and the state subtraction that partially offsets it.
What the statute says
No deduction or credit is allowed for any amount paid or incurred in carrying on a trade or business that consists of trafficking in controlled substances within Schedule I or II. Cannabis remains Schedule I federally, so the rule applies to licensed state operators regardless of state legality.
Critically, Section 280E does not reach cost of goods sold. COGS is a reduction in gross receipts required by constitutional principles of income measurement, not a deduction. Everything defensible in 280E planning flows from that distinction.
Producers versus resellers
Under the inventory rules, a reseller capitalizes the invoice cost of goods plus a narrow band of acquisition costs. A producer capitalizes direct material, direct labor and a substantial set of indirect production costs.
That is why a cultivator or manufacturer has far more room than a dispensary, and why vertical integration changes the analysis for a Minnesota microbusiness.
- Reseller: product cost, freight-in, and limited acquisition costs
- Producer: materials, production labor, utilities, facility depreciation, quality control, indirect supervision
- Neither: selling, advertising, general administration, owner draws
What the case law established
The line of cases running through Californians Helping to Alleviate Medical Problems, Olive, Alterman and Patients Mutual settled several points: a genuinely separate second trade or business can hold its own deductions; a nominal one cannot; and taxpayers without adequate records lose, regardless of the merits.
The practical lesson is unglamorous. Documentation and consistent method matter more than the cleverness of a position.
The Minnesota subtraction
Minnesota allows a subtraction for ordinary and necessary business expenses that Section 280E disallows for federal purposes. For an operator with significant disallowed expense, this is one of the most valuable items on the state return.
Capturing it requires tracking disallowed expenses through the year in the general ledger, not estimating them at filing time.
A practical compliance checklist
If you do only five things about 280E, do these.
- Design a chart of accounts that separates capitalizable and non-capitalizable costs at entry
- Code payroll by task so production labor is identifiable
- Maintain a floor plan and square-footage allocation refreshed annually
- Write a cost accounting memorandum and apply it consistently
- Track federally disallowed expenses year-round for the Minnesota subtraction
Frequently asked questions
Would rescheduling eliminate 280E?
A move to Schedule III would remove cannabis from the statute's reach prospectively. Open prior years would still be governed by the law as it stood, so records for those years remain necessary.
Does 280E apply to Minnesota's low-potency hemp products?
Hemp-derived products meeting the federal definition are outside Section 280E. Businesses selling both must keep the lines rigorously separate in their accounting.
Can an operator deduct anything at all?
Federally, only cost of goods sold reduces income for a plant-touching business. Minnesota's subtraction restores much of the rest at the state level.
