280E Tax Planning and Compliance
Internal Revenue Code Section 280E disallows ordinary business deductions for businesses trafficking in a federally controlled substance, which leaves cost of goods sold as the primary avenue for recovering costs. We build the inventory costing methodology, chart of accounts, and documentation trail that support the positions taken on your return.

How the Disallowance Works in Practice
Under 280E, selling, general, and administrative expenses are disallowed for federal income tax purposes while costs properly capitalized into inventory under the applicable inventory rules remain recoverable through cost of goods sold. The distinction is an accounting question long before it is a tax question, which is why the ledger structure matters more than year-end adjustments.
- Separation of production costs from selling and administrative costs
- Inventory costing policy documented and applied consistently
- Departmental coding at the transaction level, not in a spreadsheet at year end
- Support for allocations of shared payroll, rent, and utilities
Cost Allocation and Inventory Methodology
Cultivators, processors, and retailers each capitalize a different mix of costs, and the allocation basis has to reflect how the operation actually runs. We document square footage, labor hour, and unit-of-production allocations so the methodology can be explained the same way twice.
Production versus Retail Activity
Vertically integrated licensees often run production and retail under one entity or one campus. Separating those activities in the ledger keeps capitalizable production costs from being buried in retail overhead.
Written Accounting Policies
A short, dated memo describing the costing method, the allocation drivers, and the effective period is one of the most useful documents an operator can maintain.
Oklahoma Regulatory Context
Oklahoma licensees operate under the Oklahoma Medical Marijuana Authority and report inventory movement through the state's electronic seed-to-sale tracking system. Because state filings, license reporting, and the federal return all draw on the same underlying records, reconciling them continuously reduces the risk of inconsistent numbers across filings. State income tax treatment generally begins with federal taxable income, so 280E effects can carry into state calculations; the current treatment should be confirmed for your entity type each filing season.
Documentation and Audit Readiness
Positions that cannot be reconstructed are difficult to defend. We maintain workpapers tying the return to the trial balance, the trial balance to the subledgers, and the subledgers to production and point-of-sale records.
- Monthly reconciliations retained with supporting schedules
- Allocation workpapers with the underlying measurement data
- Standing document index so records can be produced on request
Frequently Asked Questions
- Does 280E apply to a licensed operator in Oklahoma?
- Section 280E is a federal provision and applies to businesses trafficking in a federally controlled substance regardless of state licensure. State licensing does not change the federal analysis, and any change in federal scheduling or statute would need to be evaluated when it occurs.
- Can better accounting reduce the impact of 280E?
- Accurate inventory costing determines what is properly included in cost of goods sold. That is a matter of applying the rules correctly to your facts rather than a guaranteed outcome, and results vary by license type and structure.
- What records should we keep for a 280E position?
- Keep the costing policy memo, the allocation basis data, monthly reconciliations, payroll detail by department, and the workpapers connecting the return to the general ledger.
