Cost of goods sold (COGS) refers
to the direct costs a business incurs to produce or acquire the products it sells. For cannabis businesses, COGS deductions are the expenses the IRS allows to be subtracted from gross revenue, even under the restrictions of Section 280E.
Why COGS Is the Only Major Deduction Under 280E
Section 280E of the Internal Revenue Code prohibits cannabis businesses from deducting ordinary and necessary business expenses because cannabis remains a Schedule I controlled substance under federal law. However, the US Tax Court has consistently held that COGS is not an “ordinary business deduction” — it is an adjustment to gross income. Therefore, it survives the 280E restriction. This distinction, established in cases such as Californians Helping to Alleviate Medical Problems, Inc. v. Commissioner (CHAMP, 2007), is the legal foundation for all cannabis COGS deductions.
As a result, every dollar you can legitimately add to your COGS reduces your gross profit — which is the figure 280E taxes you on. This makes COGS maximization the single most impactful tax strategy for US cannabis operators.
Which Cannabis Businesses Can Claim COGS Deductions?
All plant-touching cannabis businesses can claim COGS deductions. This includes cultivators, processors, manufacturers, and retail dispensaries. Ancillary cannabis businesses — those that do not touch the plant, such as software providers or consultants — are not subject to 280E at all and can claim all normal business deductions. For plant-touching operators, however, COGS is critical. Even a 10% improvement in COGS allocation can translate into tens of thousands of dollars in tax savings annually.
What Qualifies as COGS for Cannabis Businesses Under IRS Rules?
The IRS defines COGS broadly for cannabis businesses, and the rules differ based on whether you are a cultivator, manufacturer, or retailer. Understanding exactly what qualifies is essential to maximizing your legal deductions.
COGS for Cannabis Cultivators and Growers
For cannabis cultivators, COGS includes all costs directly associated with growing the plant. The IRS applies the IRC Section 471 inventory accounting rules to determine what costs can be absorbed into inventory and ultimately expensed through COGS. The following costs generally qualify:
Seeds, clones, and plant material
Nutrients, fertilizers, and growing media
Water and electricity directly used in the cultivation space
Direct labor wages for workers in the grow facility
Depreciation on equipment used exclusively in cultivation (lights, HVAC, irrigation)
Packaging materials applied at the cultivation stage
Additionally, cultivators who use the IRC Section 263A Uniform Capitalization (UNICAP) rules can absorb an even broader range of indirect costs into inventory. Under UNICAP, certain overhead costs — such as a portion of facility rent and management salaries tied to production — can be capitalized into inventory and later deducted through COGS when product is sold.
COGS for Cannabis Processors and Manufacturers
For cannabis processors — businesses that transform raw plant material into extracts, edibles, tinctures, or concentrates — COGS includes all conversion costs. This means the cost of raw cannabis inputs, direct labor involved in the extraction or production process, packaging materials, and equipment depreciation for production machinery. Processors often have the largest COGS allocations of any cannabis business type because their production process is more cost-intensive.
COGS for Cannabis Retailers and Dispensaries
For retail dispensaries that purchase finished cannabis products from a licensed supplier, COGS is calculated differently. Dispensaries use the inventory method, meaning COGS equals the cost of products purchased for resale plus freight and handling costs, minus the value of ending inventory. Dispensaries cannot include their own rent, payroll for budtenders, or marketing expenses in COGS — those remain non-deductible under 280E. However, they can include the wholesale cost of product, inbound shipping, and certain direct packaging costs applied before the point of sale.

Businesses Thousands in COGS Deductions
Most cannabis operators leave significant COGS deductions on the table — not because the deductions do not exist, but because of avoidable accounting errors. Here are the most costly mistakes the Tranzesta team sees regularly.
Mistake 1: Treating COGS Like a Normal Business Expense Category
Many cannabis business owners — and even inexperienced accountants — track COGS the same way a regular retailer would and stop there. They miss the opportunity to absorb indirect production costs into inventory under UNICAP rules. In cannabis accounting, COGS is not just “what you paid for product.” It is a strategic cost allocation that requires intentional, well-documented methodology.
Mistake 2: Failing to Track Inventory Accurately
COGS is calculated using inventory data: beginning inventory + purchases − ending inventory = COGS. If your inventory records are inaccurate, your COGS will be wrong — and almost certainly understated. Common inventory errors include failing to account for unsold product at year-end, misclassifying waste and spoilage, and using estimated rather than actual costs. Every dollar of understated COGS is a dollar of additional 280E taxable gross profit.
Mistake 3: Not Separating Inventory Costs from Operating Costs
Some cannabis operators bundle production and operating costs together in their books. This makes it nearly impossible to identify which costs belong in COGS and which belong in operating expenses. Since operating expenses are disallowed under 280E, clean separation is critical. Your chart of accounts must clearly distinguish between direct production costs (COGS) and everything else.
Mistake 4: Ignoring Depreciation on Production Equipment
Equipment depreciation is a legitimate COGS component for cultivators and manufacturers. However, many cannabis businesses either ignore depreciation entirely or record it as a general operating expense — where it becomes non-deductible under 280E. Correctly allocating depreciation on lights, HVAC systems, extraction equipment, and other production assets to COGS can add thousands of dollars in allowable deductions per year.
Mistake 5: Using the Wrong Inventory Accounting Method
The IRS allows cannabis businesses to use several inventory accounting methods, including FIFO (First In, First Out), LIFO (Last In, First Out), and specific identification. In a rising-cost environment, LIFO typically produces higher COGS and lower taxable income. Choosing the wrong method — or not choosing one at all — can significantly understate your deductions. This is a decision that should be made with a cannabis tax specialist, not defaulted to.
How to Maximize Cost of Goods Sold Cannabis Deductions: Step-by-Step
Follow this step-by-step system to build a COGS strategy that is legally defensible, fully documented, and maximally effective for your cannabis business in the United States.
Step 1: Set up a dedicated chart of accounts for COGS.
Create separate account categories for seeds/clones, nutrients, direct labor, packaging, equipment depreciation, utilities (production-only), and inbound freight. This separation is the foundation of an auditable COGS calculation and is the first thing an IRS examiner will look for.
Step 2: Implement a real-time inventory tracking system.
Use cannabis-specific point-of-sale and inventory management software — such as Metrc-integrated platforms — to track every gram from seed to sale. Your beginning and ending inventory values must be accurate and reconciled to physical counts at least quarterly.
Step 3: Identify all allocable indirect costs under UNICAP (Section 263A).
Work with a cannabis accountant to determine which indirect costs — such as facility rent, supervisory salaries, and utilities — can be allocated to production inventory under the UNICAP rules. For cultivators and manufacturers, this analysis alone can add 10–20% to your recognized COGS.
Step 4: Document direct labor allocations with time records.
Direct labor is one of the most valuable COGS components, but it requires documentation. Maintain time records or job cost logs that show what percentage of each employee’s time was spent on production activities versus non-production activities. Only the production portion qualifies for COGS.
Step 5: Allocate equipment depreciation to production accounts.
Work with your accountant to identify all equipment used in cultivation, processing, or production. Calculate depreciation on this equipment and allocate it to your COGS accounts rather than your general operating expense accounts. Ensure this is documented in your fixed asset register.
Step 6: Choose and consistently apply the right inventory accounting method.
Select FIFO, LIFO, or specific identification based on a tax analysis of your specific cost structure. Once you choose a method, apply it consistently across all reporting periods. Changing methods requires IRS approval and can trigger scrutiny.
Step 7: Reconcile and review COGS monthly with your accountant.
Monthly reconciliation catches errors before they compound into year-end problems. Review your COGS ratio (COGS as a percentage of revenue) each month and flag significant deviations for investigation. A cannabis tax specialist — like the team at Tranzesta — can benchmark your ratios against industry norms.

Cost of Goods Sold Cannabis Deductions: Expert Tips for 2026
Beyond the fundamentals, these advanced strategies separate cannabis businesses that minimize their tax burden from those that overpay year after year. Tranzesta recommends all of the following to its cannabis clients in the United States.
Use standard costing for high-volume cultivation. If you grow large quantities of a standardized product, standard costing assigns a predetermined cost per gram or unit and simplifies COGS calculation without sacrificing accuracy. This approach is easier to defend in an audit than highly variable actual-cost calculations.
Track waste and spoilage separately — and correctly. Cannabis plants that die, product that fails quality testing, or inventory that expires must be tracked and written off through COGS, not operating expenses. Proper waste accounting directly reduces your taxable gross profit.
Allocate shared facility costs with a defensible methodology. If your facility houses both production and non-production activities — for example, cultivation and a customer lounge — you must allocate shared costs like rent and utilities between COGS and non-deductible operating expenses. Use square footage, hours of use, or headcount ratios, and document your methodology in writing.
Consider a cost segregation study for your facility. If you own your cannabis facility, a cost segregation study can accelerate depreciation on production-related components of the building, moving more depreciation into COGS sooner. This is particularly valuable for cultivators with significant facility investments.
Prepare a COGS memorandum for your records. Annually document your COGS methodology, the costs included, the allocation ratios used, and the legal authority for each inclusion. This memorandum is your first line of defense in any IRS examination and demonstrates that your deductions are intentional and well-reasoned.
Monitor rescheduling developments closely. If cannabis is moved from Schedule I to Schedule III at the federal level, Section 280E may no longer apply — unlocking all ordinary business deductions immediately. Businesses with strong COGS practices will be best positioned to benefit because their books will already be clean and their cost structures will be well understood.

Conclusion: Claim Every COGS Deduction You Are Legally Entitled To
The three most important takeaways from this guide are: first, cost of goods sold cannabis deductions are the only major tax relief available to plant-touching cannabis businesses under Section 280E, and maximizing them is not optional — it is essential. Second, COGS is far broader than most cannabis operators realize; direct labor, equipment depreciation, indirect production costs, and allocated overhead can all qualify when documented correctly. Third, accurate inventory tracking is the foundation of every COGS deduction — without it, everything else falls apart.
The cannabis industry is one of the most heavily taxed sectors in the United States. However, a well-executed COGS strategy can significantly reduce that burden — legally, systematically, and sustainably.

FAQs
Cost of goods sold for a cannabis dispensary includes the wholesale purchase price of all cannabis products acquired for resale, inbound freight and shipping costs to receive inventory, and direct packaging costs applied before the point of sale. It does not include retail staff wages, rent, utilities for the retail space, or marketing expenses — those remain non-deductible under IRS Section 280E for plant-touching dispensaries. Dispensaries calculate COGS as: beginning inventory plus purchases minus ending inventory.
Cannabis businesses can deduct labor costs under Section 280E only if those labor costs are directly tied to production or acquisition of cannabis products and are therefore classified as part of COGS. For cultivators and processors, wages paid to workers who grow, harvest, trim, or process the plant qualify as COGS direct labor. Wages for retail staff, administrative employees, or sales personnel do not qualify and remain non-deductible under 280E. Proper time-tracking records are essential to support any direct labor COGS deduction.
COGS reduces taxes for cannabis businesses by lowering their gross profit, which is the taxable income figure under Section 280E. Unlike ordinary business deductions — which 280E disallows — COGS is treated as an adjustment to gross receipts rather than a traditional deduction. The higher your COGS, the lower your gross profit, and therefore the lower your federal and state income tax. For example, a dispensary with $2 million in sales and $900,000 in COGS pays tax on $1.1 million in gross profit rather than the full $2 million.
The UNICAP rule — found in IRC Section 263A — requires certain businesses to capitalize indirect costs into inventory rather than expensing them immediately. For cannabis cultivators and manufacturers, UNICAP is a significant opportunity. It allows indirect costs such as a portion of facility rent, supervisory salaries, and utilities attributable to production to be absorbed into inventory value. When that inventory is sold, those capitalized costs flow through COGS and reduce taxable gross profit. Applying UNICAP correctly can meaningfully increase a cannabis business’s allowable COGS.
Rescheduling cannabis from Schedule I to Schedule III under the Controlled Substances Act would likely eliminate the Section 280E restriction, because 280E applies only to Schedule I and II substances. If cannabis is rescheduled, plant-touching cannabis businesses could deduct all ordinary and necessary business expenses — rent, salaries, marketing, and more — just like any other US business. COGS deductions would remain available but would become less critical as a standalone strategy. Cannabis businesses should monitor federal rescheduling developments closely and work with a qualified tax advisor to plan accordingly.
