For a dispensary, inventory cost is almost the entire deduction. IRC Section 280E disallows ordinary business deductions for adult-use activity, leaving cost of goods sold as the only meaningful federal deduction. A retailer's cost of goods sold is essentially what was paid for the product on the shelf.
Everything that makes the store run falls outside it. Rent, budtender wages, security, point of sale, marketing and insurance are all disallowed. That makes how you cost and track inventory the highest-leverage accounting decision a new dispensary makes.
Initial inventory for a cannabis retailer is a cash problem and a tax problem at the same time, and most opening plans underestimate both. You pay for product before it sells, in a sector where vendors rarely extend credit and banking is constrained. Then you are taxed on gross profit rather than net income, because 280E disallows the operating expenses that would normally reduce it.
Cost of goods sold for a reseller is narrow by design. Under the Section 471 inventory rules, a retailer generally capitalises the invoice price net of trade discounts, plus transportation and other necessary charges incurred in acquiring possession. Cultivators and manufacturers can absorb a meaningful share of production overhead into inventory. Retailers cannot.
So the practical work is precision rather than creativity. Capture every capitalisable cost correctly, reconcile the ledger to seed-to-sale from the first delivery, count physically, and document the methodology while you are using it rather than reconstructing it later.

The Structural Problem
Why Retail Inventory Drives the Tax Bill.
Cultivators and manufacturers get a meaningful advantage under 280E that retailers do not. Understanding why explains everything about how a dispensary should handle inventory.
A producer builds inventory, so a share of production overhead legitimately becomes part of what that inventory cost. Cultivation labour, growing space, equipment depreciation and utilities used in production can be absorbed into inventory value and recovered through cost of goods sold.
A retailer buys finished product. There is no production process to absorb overhead into, so the cost of goods sold figure stays close to what was paid for the goods. Everything else the store spends money on sits below gross profit, where 280E disallows it.
What that means in practice
Two businesses with identical revenue and identical total costs can owe materially different federal tax purely because one produces and the other resells. That is not an argument for vertical integration on its own, since integration brings its own costs and licensing requirements. It is an argument for a retailer to be meticulous about the narrow deduction available, because there is no second lever.
The authority here is settled rather than open. The IRS confirmed in Chief Counsel Advice 201504011 that a cannabis taxpayer computes cost of goods sold using the Section 471 inventory rules as they stood when 280E was enacted, not the broader capitalisation rules that came later. Attempts to use Section 263A to pull disallowed expenses into inventory have been rejected. Medical operations sit outside 280E federally since April 2026, which we cover in our guide to cannabis rescheduling and 280E.

The Line That Matters
What a Retailer Can Capitalise.
Under the Section 471 reseller rules, inventory cost is the invoice price less trade discounts, plus the necessary charges incurred in acquiring possession of the goods. The list is shorter than most operators expect.
Goes into inventory cost
- Invoice price of the product, net of trade discounts
- Transportation and freight in, getting product to your premises
- Excise paid on acquisition, where the structure places it on the buyer
- Certain necessary charges incurred in taking possession
- Costs of receiving and inspecting incoming inventory, where directly attributable
Stays below gross profit
- Store rent, utilities and occupancy
- Budtender wages and sales floor payroll
- Security, cameras and compliance systems
- Point of sale software and seed-to-sale subscriptions
- Marketing, advertising and loyalty programmes
- Insurance, professional fees and general administration
The second column is where most of a dispensary's spend actually sits, and none of it reduces federal taxable income for adult-use activity. That is the whole shape of the 280E problem for retail.
One nuance worth getting right: the boundary between receiving inventory and selling it. Work directly attributable to acquiring and taking possession of goods can sit differently from work on the sales floor. The distinction has to be supportable with real records rather than an after-the-fact allocation percentage.
Currently booking everything to one expense account?That is the most common finding when we review a new dispensary, and it usually means tax was overpaid. See tax planning and compliance →
A Position With a Health Warning
Section 471(c) and the Risk Attached.
You will hear Section 471(c) discussed as a way to widen the cost of goods sold figure. The argument deserves a straight explanation, including the part that usually gets left out.
The Tax Cuts and Jobs Act let small business taxpayers below a gross receipts threshold, indexed annually for inflation, use a simplified inventory method. Such a taxpayer may account for inventory in line with its applicable financial statements, or absent those, in line with its own books and records. The argument runs that a qualifying cannabis business could therefore define inventory more broadly in its books, pulling costs into cost of goods sold that 280E would otherwise disallow.
Why this is an aggressive position rather than a settled one
The IRS has issued no guidance endorsing this reading, and there is no reason to assume it will accept one that reduces the reach of 280E. The Service has already rejected the analogous argument under Section 263A, concluding that using capitalisation rules to recover otherwise-disallowed expenses defeats the purpose of the statute.
Practitioners taking the position commonly disclose it on Form 8275-R, which exists specifically for positions contrary to regulations. That disclosure reduces certain penalty exposure. It does not make the position correct, and it signals the filing for attention.
Whether it makes sense depends on the amounts involved, your appetite for an examination, and advice from someone who will stand behind the position. Treat anyone presenting it as a straightforward planning technique with caution.
Gross receipts thresholds index annually. Confirm the current figure and your eligibility before considering any position that depends on it.
Sizing the Order
How Much Opening Inventory to Buy.
There is no universal number, because product mix, store size, local pricing and supply availability all move it. What can be stated is the method, and the trade-off sitting behind it.
Too little looks worse than it costs
A thin opening range in the first weeks does lasting damage, because early customers form a view of whether your store is worth returning to.
Gaps in core categories are the expensive version. Missing a niche product is survivable; having no flower in a popular price band is not.
Too much is cash you cannot get back
Overbuying ties up capital in a business already strained by 280E, and cannabis inventory degrades. Product bought on a guess about demand tends to become the discount bin.
Markdowns hurt twice here: lost margin, and the disallowed marketing spend often used to move the stock.
Build from turnover, not from budget
Work back from expected weekly units by category and your supplier lead time, then hold enough to cover that cycle with a buffer.
Reorder frequently in small quantities at first. It costs slightly more per unit and tells you what actually sells before you commit capital.
A sensible opening approach
- Cover every core category at two or three price points rather than stocking one category deeply
- Buy shallow across breadth, since the first month is market research you are paying for either way
- Agree restocking cadence with suppliers before opening, so a fast seller can be replaced in days
- Hold back part of the inventory budget for week three, once real demand data exists
- Track sell-through by SKU from day one, using a cannabis financial dashboard, and let the second order be evidence-led

The Cash Trap
Paying for Inventory Before It Sells.
In most retail sectors a new store negotiates supplier terms and sells some stock before paying for it. Cannabis rarely works that way, and the difference is significant enough to break an opening cash plan.
Why terms are tighter here
- Banking constraints make credit assessment and collection harder for suppliers
- Regulatory risk on both sides encourages payment on or before delivery
- A new licensee has no trading history to extend credit against
- Payment rails are limited, so settlement is slower and more manual
Assume you pay up front until a supplier tells you otherwise. Model it that way, and treat any credit you are offered as upside rather than as the plan.
The second hit
Under 280E you are taxed on gross profit rather than net income. So in a period where you have bought heavily and sold moderately, cash has left the business while taxable income has not fallen by the amount an ordinary business would expect. Estimated tax payments come due on a position that does not reflect how much cash is actually in the account.
That is why a thirteen-week cash forecast, which sits within outsourced CFO work, belongs beside the inventory plan rather than after it. The two are the same decision viewed from different angles.
Has your opening plan assumed supplier credit?If so, rebuild it on payment at delivery. The gap between those two assumptions is where new dispensaries run short. Rework the forecast →
Before the First Delivery
Systems to Have Running on Day One.
Inventory as a balance sheet asset with cost of goods sold recognised on sale, not product purchases expensed as they arrive.
Freight and other acquisition charges allocated to the goods they relate to, rather than booked separately where they lose their character.
Your tracking system and your ledger reconciled monthly from the first delivery, so variances surface while they are still explainable.
Cost held per SKU rather than per order, since margin by product is what pricing and reorder decisions depend on.
A scheduled count with a documented procedure, and a defined process for investigating and recording variances.
What you capitalise, what you do not, and why, recorded at the time. That document is what an examiner asks for first.
Setting these up before the first delivery costs a fraction of reconstructing a year of inventory movements at filing.
First delivery arriving soon?
Inventory costing decided before product lands is straightforward. Decided afterwards, it becomes a reconstruction exercise.
The Slow Leak
Shrinkage, Waste and Dead Stock.
Inventory losses cost a cannabis retailer more than they cost other retailers, for the same reason everything else does. Product written off was paid for with money that reduced your deduction only to the extent the rules allow, and the lost sale takes the margin with it.
Where it goes
- Expiry. Edibles and some concentrates carry real shelf life. Ageing stock needs visibility before it becomes a write-off.
- Degradation. Flower loses quality with time and poor storage, and a customer who buys dry product does not return.
- Count variance. Differences between recorded and physical stock, which regulators treat seriously and examiners treat as a records problem.
- Theft. Internal and external, and the security spend that addresses it is itself disallowed for adult-use.
- Dead stock. Product that simply does not sell, occupying shelf space and capital.
Handling it properly
Setting the ledger up correctly sits within cannabis accounting services. Record write-offs and disposals as they happen, with the reason and the authorisation. Most states require documented destruction procedures, and the same record supports the accounting treatment. A stock adjustment with no explanation behind it is a problem in a regulatory inspection and a weakness in a tax examination.
State rules on destruction differ considerably, so check your own market against our state-by-state cannabis practice.
Watch ageing weekly rather than monthly. A discount applied at week six recovers more than a write-off at week twelve, and the decision only exists if someone can see the ageing.
What Goes Wrong
Mistakes That Cost the Most.
| Mistake | What It Costs |
|---|---|
| Expensing purchases instead of capitalising them | Cost of goods sold no longer matches sales, so taxable income is wrong in both directions across periods and the position is hard to defend. |
| Omitting freight and acquisition charges | Understates inventory cost, which understates the only deduction available. Tax is overpaid quietly and repeatedly. |
| Booking store costs into cost of goods sold | Overstates the deduction in a way an examiner unpicks quickly, and undermines confidence in the whole return. |
| Never reconciling seed-to-sale to the ledger | Variance accumulates until neither number can be trusted, creating exposure in both regulatory inspection and tax examination. |
| Holding cost by order rather than by SKU | Margin per product becomes invisible, so pricing and reorder decisions are made on instinct instead of evidence. |
| No written costing methodology | The approach cannot be shown to be consistent, which is the first thing questioned when a return is reviewed. |
Before your first delivery, confirm
- Inventory sits on the balance sheet, with cost of goods sold recognised on sale
- Freight and acquisition charges are captured against the goods they relate to
- Store operating costs are booked below gross profit, separately from inventory
- Cost is held at SKU level rather than order level
- Seed-to-sale and the ledger reconcile, with a monthly cadence agreed
- A physical count schedule and variance procedure exist in writing
- Your costing methodology is documented and someone owns it

Common Questions
Cannabis Retail Inventory FAQs.
Costing and 280E
What can a cannabis retailer include in cost of goods sold?
Under the Section 471 reseller rules, generally the invoice price of the product net of trade discounts, plus transportation and other necessary charges incurred in acquiring possession of the goods. That is a narrow list. Store rent, budtender wages, security, point of sale software, marketing and insurance all fall outside it and are disallowed federally for adult-use activity under IRC Section 280E. Cultivators and manufacturers can absorb a share of production overhead into inventory; a retailer buying finished product cannot.
Why do cultivators get a bigger deduction than dispensaries?
Because they produce inventory rather than resell it. A producer legitimately capitalises part of its production overhead into the value of what it makes, including cultivation labour, growing space and equipment depreciation, and recovers that through cost of goods sold. A retailer has no production process to absorb overhead into, so cost of goods sold stays close to what was paid for the goods. Two businesses with the same revenue and the same total costs can therefore owe materially different federal tax depending on which side of that line they sit.
Can I use Section 263A to capitalise more costs?
No. The IRS confirmed in Chief Counsel Advice 201504011 that a cannabis taxpayer computes cost of goods sold using the Section 471 inventory rules as they existed when 280E was enacted, rather than the broader capitalisation rules introduced later. The reasoning is that allowing Section 263A would let disallowed expenses re-enter through inventory and defeat the statute. Attempts to take that position have been rejected in the Tax Court, so it is not an open question.
Buying and cash
How much opening inventory should a dispensary buy?
Work back from expected weekly units by category and supplier lead time rather than starting from a budget figure. A practical approach covers every core category at two or three price points, buys shallow across that breadth, and holds part of the budget back for week three once real demand data exists. Reordering frequently in smaller quantities costs slightly more per unit and reveals what actually sells before you commit capital. Gaps in core categories damage a new store more than missing niche products do.
Will suppliers give a new dispensary credit terms?
Usually not at first. Banking constraints make credit assessment and collection harder for cannabis suppliers, regulatory risk on both sides encourages payment on or before delivery, and a new licensee has no trading history to lend against. Build the opening cash plan assuming payment at or before delivery, and treat any terms you are offered as upside rather than as the plan. The gap between those two assumptions is where new dispensaries most often run short.
Why does inventory hurt cash flow more in cannabis?
Two reasons compound. You typically pay for product before selling it, with little or no supplier credit. Then under 280E you are taxed on gross profit rather than net income, so in a period of heavy buying and moderate selling, cash leaves the business while taxable income does not fall the way an ordinary business would expect. Estimated tax payments come due on a position that does not reflect the cash actually available, which is why a thirteen-week forecast belongs beside the inventory plan.
Systems and records
What inventory systems do I need before opening?
Inventory recorded as a balance sheet asset with cost of goods sold recognised on sale, rather than purchases expensed as they arrive. Landed cost capture so freight attaches to the goods it relates to. Cost held at SKU level rather than order level. Seed-to-sale reconciled to the ledger monthly from the first delivery. A physical count schedule with a written variance procedure. Finally, a documented costing methodology stating what you capitalise and why, because that document is what an examiner asks for first.
How often should I reconcile inventory to seed-to-sale?
Monthly at minimum, starting with the first delivery rather than once a problem appears. Variance is explainable while it is small and recent; six months of accumulated difference is neither. Regulators treat tracking discrepancies seriously, and in a tax examination an unreconciled inventory position undermines the cost of goods sold figure that carries your entire deduction. Physical counts on a defined schedule sit alongside this, with every adjustment recorded with its reason and authorisation.
How should write-offs and waste be handled?
Record them as they occur, with the reason, the quantity, the cost and who authorised it. Most states also require documented destruction procedures, and the same record supports both the regulatory and the accounting position. An unexplained stock adjustment is a problem in an inspection and a weakness in an examination. Reviewing ageing weekly rather than monthly matters too, since a discount at week six recovers more value than a write-off at week twelve, and that choice only exists if someone can see the ageing.
