Navigating 280E: How Cannabis Businesses Handle America’s Most Punitive Tax Code — and What Changes With Schedule III

No single provision of federal law has inflicted more financial damage on the legal cannabis industry than Section 280E of the Internal Revenue Code. Enacted in 1982 after a drug dealer successfully claimed business deductions on his tax return, Section 280E denies all standard business deductions and credits to any business that traffics in Schedule I or Schedule II controlled substances. For nearly a decade of modern legal cannabis, this meant that dispensaries, cultivators, and manufacturers paying state and local taxes, employing thousands of workers, and operating in full compliance with state law were simultaneously treated by the IRS as criminal enterprises unworthy of the deductions available to every other legal business in America.

The financial impact has been staggering. Cannabis businesses have routinely faced effective federal tax rates of 50% to 80%, compared to the 21% corporate rate that applies to other industries. A dispensary generating $2 million in gross revenue and $400,000 in net income before deductions might owe $500,000 or more in federal taxes — a rate that would bankrupt businesses in any other sector.

With the reclassification of cannabis to Schedule III finalized in late 2025, the 280E landscape has shifted dramatically. But understanding where the industry has been is essential to navigating where it is going.

How 280E Actually Works

Section 280E is deceptively simple in its language: “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.”

In practical terms, this means that cannabis businesses could not deduct:

• Rent for retail or cultivation space
• Employee wages (except those directly tied to production)
• Marketing and advertising costs
• Professional services (legal, accounting, consulting)
• Insurance premiums
• Utilities not directly tied to production
• Administrative costs
• Depreciation on non-production equipment

The only costs that 280E-affected businesses could deduct were Cost of Goods Sold (COGS) — the direct costs of producing or acquiring the products they sell. This distinction created the central strategy around which cannabis tax planning revolved.

The COGS Strategy: What Worked

Under IRS rules, COGS includes direct material costs, direct labor involved in production, and a portion of overhead directly attributable to the production process. Cannabis businesses, guided by aggressive (and sometimes creative) tax advisors, sought to maximize the expenses they could classify as COGS.

Cultivators had the most straightforward case. Seeds, growing media, nutrients, water, electricity for grow lights, and the wages of cultivation employees all qualify as direct production costs. The IRS generally accepted these deductions, though disputes arose over the allocation of shared overhead (such as HVAC systems that serve both production and office areas).

Manufacturers and processors similarly benefited from relatively clear COGS classifications. The cost of raw cannabis inputs, extraction solvents, packaging materials directly enclosing the product, and production labor are direct costs. Some manufacturers structured their operations to maximize production-floor footprint relative to office space, allowing a larger share of rent and utilities to be allocated to COGS.

Retailers and dispensaries faced the greatest challenge because their primary activity is selling, not producing. A dispensary that purchases finished products from a distributor has limited COGS — essentially just the wholesale cost of inventory. The rent, wages, security, point-of-sale systems, and marketing that constitute the majority of dispensary operating costs were all non-deductible under 280E.

The Two-Entity Structure

The most widely used structural strategy was the two-entity approach. A cannabis business would create two separate legal entities: one that held the cannabis license and conducted the plant-touching operations, and a second management company that provided services — management, real estate, staffing, intellectual property licensing — to the cannabis entity.

The management company, because it did not directly traffic in controlled substances, was not subject to 280E and could deduct its expenses normally. The cannabis entity would pay the management company for its services, and while those payments were non-deductible for the cannabis entity under 280E, they were ordinary income to the management company, which could offset that income with its own deductions.

The IRS challenged this structure aggressively, and the results were mixed. In several Tax Court cases, the IRS argued that the management company was essentially an alter ego of the cannabis business and should be disregarded for tax purposes. Courts sometimes agreed, particularly when the two entities shared ownership, management, and office space. In other cases, where the entities maintained genuine operational separation, the structure was upheld.

The key factors that determined whether a two-entity structure survived IRS scrutiny included:

• Separate bank accounts and financial records: The entities needed to maintain genuinely independent finances.
• Arm’s length pricing: The fees charged by the management company needed to be comparable to what an unrelated party would charge for similar services.
• Operational independence: Separate employees, separate management decisions, and clear documentation of each entity’s distinct functions.
• Non-overlapping ownership: Having different ownership structures (even if related parties held interests) strengthened the case.

The Schedule III Shift

The reclassification of cannabis to Schedule III, effective since late 2025, fundamentally altered the 280E analysis. By its plain language, Section 280E applies only to businesses trafficking in Schedule I and Schedule II substances. With cannabis now classified as Schedule III, 280E no longer applies to cannabis businesses operating in compliance with state law.

This means that for the 2026 tax year and beyond, cannabis businesses can:

• Deduct rent, utilities, and all facility costs
• Deduct employee wages at all levels
• Deduct marketing and advertising expenses
• Deduct professional services fees
• Claim depreciation on equipment and leasehold improvements
• Utilize tax credits (R&D credits, energy efficiency credits, etc.)
• Carry forward net operating losses from prior years (subject to limitations)

The financial impact is transformative. Industry analysts estimate that the elimination of 280E will reduce the average cannabis business’s effective federal tax rate from roughly 60% to the standard corporate rate of 21% — freeing up billions of dollars annually across the industry.

Retroactive Claims: The Open Question

One of the most contentious issues in cannabis tax law is whether businesses can file amended returns to claim 280E-denied deductions for prior tax years. The statute of limitations for filing amended returns is generally three years from the filing date, meaning that at the time of reclassification, the 2022, 2023, and 2024 tax years were potentially open.

The IRS has taken the position that 280E applied to those years because cannabis was classified as Schedule I during those periods, and the reclassification was not retroactive. Several cannabis businesses have filed amended returns anyway, and the resulting disputes are likely to produce Tax Court litigation that will not be resolved for years.

Tax advisors are split on the merits. Some argue that the reclassification implicitly acknowledges that cannabis should not have been Schedule I in the first place, creating an argument for retroactive relief. Others view the IRS position as legally sound and counsel clients against the expense and risk of pursuing amended returns.

What Cannabis Businesses Should Do Now

For cannabis operators navigating the post-280E landscape, several priorities are clear:

Restructure accounting systems. Businesses that spent years maximizing COGS allocations need to restructure their chart of accounts to accurately capture deductible expenses that were previously irrelevant for tax purposes. Many cannabis accounting systems were designed around 280E constraints and need to be rebuilt.

Evaluate entity structures. The two-entity structures that were essential under 280E may no longer be necessary or optimal. Collapsing entities can reduce administrative overhead and simplify compliance, though there may be state tax or liability reasons to maintain separate structures.

Revisit compensation strategies. Under 280E, many cannabis businesses minimized owner compensation to reduce non-deductible expenses. With deductions now available, owners can restructure compensation in ways that are more tax-efficient and better reflect the value they provide.

Invest the savings. The most forward-thinking operators are reinvesting their 280E savings into growth — expanding into new markets like Georgia’s recently expanded medical program, investing in technology and automation, and building the brand infrastructure that was prohibitively expensive under 280E’s punitive regime.

Engage qualified professionals. Cannabis tax law remains specialized, and the transition from a 280E to a non-280E environment is complex. Work with a CPA and tax attorney who have specific cannabis industry experience.

The Broader Business Implications

The end of 280E does more than reduce tax bills — it reshapes the competitive landscape. Under 280E, cannabis was structurally biased toward vertically integrated operations because cultivators and manufacturers could deduct production costs as COGS while standalone retailers could not. With all businesses now able to deduct their operating expenses, the playing field levels, potentially benefiting independent dispensaries that were disproportionately burdened.

The improved economics also change the calculus for venture capital investors evaluating cannabis opportunities. Businesses that were marginal or unprofitable under 280E may become compelling investments in a post-280E world, and the due diligence process now focuses on operational efficiency and market position rather than the tax engineering that previously determined financial viability.

For consumers, the impact will be indirect but real. Cannabis businesses operating with normal tax rates have room to reduce prices, improve product quality, invest in customer experience, and build the kind of competitive, innovative market that benefits everyone. The development of better consumer-facing cannabis apps and tools, more accessible educational resources like the best cannabis books of 2026, and the acceleration of clinical research on topics from sleep apnea treatments to neuroprotection — all of these are downstream effects of an industry finally able to operate with the same financial footing as every other legal business.

The 280E era is over. The challenge now is building an industry worthy of the opportunity.
