What Cannabis Businesses Can (and Can't) Deduct Under 280E in 2026

Section 280E is the most expensive tax provision in cannabis — not because it taxes revenue directly, but because it erases the business deductions every other industry takes for granted. A dispensary spending $1.2 million to run a $2 million operation pays federal income tax as if it had almost no costs at all. Most operators know this in broad strokes. Fewer know exactly which expenses are blocked, which are protected, and where the gray areas live.

The good news: there is one legitimate carve-out that most cannabis businesses don't fully exploit. Understanding the boundary between what's blocked and what's protected is where meaningful tax savings come from.

What 280E Actually Blocks

Section 280E denies all deductions under IRC §162 (ordinary and necessary business expenses) and §212 (expenses for production of income). In plain terms: if an expense is normally deductible because you're running a business, 280E disallows it — because your business involves federally controlled substances.

Expenses that are blocked for cannabis businesses include:

• Retail rent and utilities for dispensary or office space
• Non-production payroll — budtenders, administrative staff, marketing employees
• Advertising and marketing spend
• Professional fees — legal, accounting, consulting
• Insurance premiums
• Software subscriptions (POS systems, accounting tools, compliance platforms)
• Banking fees

These are the same expenses every other business in America deducts without a second thought. A restaurant can deduct its rent, its servers' wages, and its accounting fees. A cannabis dispensary cannot — at the federal level.

What You Can Still Deduct: The COGS Exception

Here is the one lever cannabis businesses can legally pull: Cost of Goods Sold (COGS) is not a §162 deduction — it's an adjustment to gross income under IRC §471, which governs inventory accounting. Because 280E only prohibits §162 and §212 deductions, it does not touch COGS.

Every dollar correctly classified as COGS reduces taxable income dollar-for-dollar, just as it would for any other business. This is not a loophole or an aggressive position — it's the explicit carve-out recognized by the IRS and upheld in Tax Court. The question is not whether you can use it, but whether you're capturing everything you're entitled to.

Operators who rigorously document and correctly classify their production costs routinely carry effective tax rates 15–25 percentage points lower than peers with identical gross margins who don't maximize their COGS allocation.

Deductible COGS by Business Type

What counts as COGS varies by where you sit in the supply chain. The IRS applies different inventory accounting rules to retailers, cultivators, and processors — and the differences matter.

Dispensaries / Retailers

For a pure retailer, COGS is relatively narrow: the invoice cost of inventory purchased from a licensed supplier, plus inbound freight and direct receiving labor to bring that inventory to a saleable condition. What cannot be included: budtender wages, POS software, point-of-sale marketing materials, or any portion of rent attributable to the retail floor. Dispensaries typically have the highest effective tax rates in the supply chain precisely because their COGS base is the smallest relative to revenue.

Cultivators / Growers

Cultivators have more to work with. Direct production costs that can flow into COGS include: seeds and clones, soil and growing media, nutrients and amendments, water, electricity consumed in the grow facility, cultivation labor (trimmers, irrigators, canopy managers), and depreciation on grow equipment. What stays out: administrative salaries, delivery drivers, and any overhead tied to non-production activities. The key is separating the production space from everything else — both physically and in your accounting records.

Processors / Manufacturers

Processors can include the raw material cost (biomass or flower purchased for extraction), direct production labor, depreciation on extraction equipment, and facility costs directly tied to manufacturing operations. What cannot be included: sales staff compensation, corporate overhead, and any general and administrative expenses. As with cultivation, the documentation burden is high — every cost flowing into COGS needs a paper trail linking it to production activity.

Vertically Integrated Operators

Vertical operators — those who cultivate, process, and retail under one umbrella — face the most complexity. Each segment has its own COGS base, and intercompany transfers must be documented at arm's length; you cannot artificially inflate the transfer price between your cultivation entity and your retail entity to shift income. Mixed-use employees who work across production and retail functions require a time-allocation methodology applied consistently period to period. The reward for getting this right is a substantially larger combined COGS deduction than any single-segment operator achieves.

The Gray Areas: Expenses That Could Go Either Way

Several expense categories sit at the boundary between deductible COGS and non-deductible operating costs. These require judgment calls backed by documentation.

• Shared-space utilities — If a building serves both a production floor and a retail showroom, you can allocate the portion of rent and utilities tied to production into COGS. Allocation by square footage is the most defensible methodology. Document it in writing and apply it consistently; changing your allocation method mid-audit is a red flag.
• Dual-role employees — A manager who spends half their time supervising the grow and half managing the retail counter can have 50% of their wages included in COGS. But you need contemporaneous time records — not a post-hoc estimate. The IRS audits cannabis businesses at elevated rates, and unsupported allocations are among the first things challenged.
• Packaging — Packaging that is necessary to make the product saleable (child-resistant containers required by state law, tamper-evident seals) can generally be included in COGS as a production cost. Pure marketing packaging — branded boxes, decorative tins, branded bags beyond what compliance requires — typically cannot.
• Delivery costs — Inbound freight (the cost to receive inventory) can flow into COGS as a cost of acquiring goods. Outbound delivery costs (getting product to customers) generally cannot — those are selling expenses, which 280E blocks.

What the IRS Will Want to See

Getting the classification right matters less if you can't prove it. Cannabis businesses are audited at substantially higher rates than most industries, and COGS allocation is typically the first area the IRS examines. Build your documentation posture before you need it:

• Separate chart of accounts from day one — Production costs and G&A costs should live in distinct account categories, not intermixed. Reclassifying expenses after the fact looks opportunistic and is harder to defend.
• Time cards and payroll records showing functional allocation — For any employee whose wages are split between production and non-production, you need contemporaneous records. A retroactive spreadsheet made during an audit carries very little weight.
• Invoices and receipts filed by expense category — Organized by function, not just by vendor. "I bought it from this supplier" is not the same as "this expense went into production."
• Consistent methodology applied across periods — The allocation approach you use in Year 1 should be the same in Year 3. Inconsistency signals opportunism to an examiner, even if each year's approach was defensible in isolation.

The Bottom Line for 2026

Cannabis businesses have one primary deduction strategy: maximize COGS. Every other cost reduction matters — operational efficiency, vendor negotiations, overhead management — but COGS is the only direct lever that offsets the 280E penalty. Operators who document rigorously and classify correctly routinely outperform peers by 15–25 percentage points in effective tax rate, on identical gross margins.

On the legislative front: DEA rescheduling of cannabis from Schedule I to Schedule III would eliminate 280E entirely, because the provision only applies to substances prohibited under the Controlled Substances Act's Schedule I and II. That rescheduling process is ongoing as of mid-2026 but is not finalized. Don't plan your business around it; do plan to benefit from it if it happens. Until then, 280E applies in full, and COGS maximization is the game.
