Does 280E Still Apply in 2026? Medical vs. Adult-Use Cannabis After Schedule III

Does 280E Still Apply in 2026?

The short answer for most New York operators is that Section 280E continues to govern the federal return until a change is final and effective for the tax year being filed, and no operator should file a position that assumes otherwise without professional advice on their specific facts. Rescheduling cannabis from Schedule I to Schedule III would, by the plain terms of Internal Revenue Code Section 280E, change the analysis, because the provision reaches trafficking in controlled substances listed in Schedule I or Schedule II. The federal administrative process, its final effective date, and the Treasury and IRS positions that would follow it are the unresolved part. Nothing in this guide should be read as a statement that 280E has universally disappeared for cannabis businesses. It has not.

What operators should take from 2026 is narrower and more useful: cannabis activity should no longer be assumed to receive one uniform federal tax treatment across every license, every product line, and every tax year. Medical and adult-use activity, different periods, and different entities within the same group may not sit in the same place. That possibility is an accounting design question long before it is a filing question. Our New York 280E tax compliance services address the filing side; this guide covers the records that any position will depend on.

• Section 280E remains the operating assumption for federal filings until a change is final and effective
• New York decoupled for state purposes, so the state and federal computations already diverge
• Treasury and IRS treatment of any transition, including allocation between periods or activities, is unresolved
• Accounting preparation is available now; tax positions should wait for guidance and professional advice

Medical vs. Adult-Use Cannabis: Why the Difference Matters for 280E

New York runs two distinct programs under the Office of Cannabis Management and the Cannabis Control Board: a medical cannabis program serving certified patients through registered organizations, and an adult-use market serving retail consumers through licensed dispensaries supplied by licensed cultivators, processors, and distributors. Several New York registered organizations hold both medical and adult-use authority and operate them from overlapping facilities, staff, and systems. That is precisely the structure that makes the 280E question a bookkeeping problem rather than an abstract one.

The distinction matters because any federal change is likely to turn on how a specific activity is characterized, not on how a company describes itself. Tax treatment follows the trade or business and the records that substantiate it. An operator whose ledger cannot separate medical revenue, medical cost of goods sold, and the labor and overhead consumed by medical activity from the adult-use side of the same building has no factual basis for treating the two differently, whatever the law eventually permits. The separation has to exist in the accounting before it can be claimed on a return.

The Mixed-Use Cannabis Accounting Problem

Consider a hypothetical New York registered organization operating a single facility in the Hudson Valley with a cultivation and processing operation upstairs, a medical dispensing counter serving certified patients, and an adult-use retail floor open to consumers. One general manager, one security contract, one insurance policy, one utility meter, one accounting firm, one point-of-sale vendor with two configurations, and one payroll running across all of it. If federal treatment of medical and adult-use activity ever diverges, this operator will be asked a question their current books almost certainly cannot answer: how much of each shared cost belongs to which activity, and what evidence supports the number?

That is the mixed-use accounting problem in its plainest form. It is not solved by a year-end spreadsheet. A retroactive allocation is an estimate, and an estimate prepared after the fact is the weakest form of support in an examination. A contemporaneous ledger entry carrying a department, a location, and an activity dimension is a record. The work of converting the first into the second is ordinary cannabis bookkeeping discipline applied earlier than usual.

• Revenue segmentation: medical and adult-use tracked as separate revenue streams at the source, not merged and split later
• Departments and classes: dispensing counter, retail floor, cultivation, processing, and administration as distinct cost centers
• Chart of accounts: activity-aware accounts so that an expense lands correctly on entry rather than in a reclass
• Direct expenses: costs consumed by one activity only, identified and coded as such
• Indirect and shared expenses: rent, utilities, security, software, insurance, management, and professional services, tracked with a documented basis
• Payroll: hours captured by actual activity where employees genuinely work across both sides
• Inventory and COGS: costing maintained by product, batch, and destination activity
• POS and seed-to-sale records: BioTrack and register data that reconcile to the ledger without a manual bridge
• Contemporaneous documentation: the allocation basis written down and applied consistently during the period

Cannabis 280E Expense Allocation and Apportionment

Expense allocation and apportionment is where a divergence between activities would create the most accounting work. Under current law, the 280E analysis already forces a line between costs that can be capitalized into inventory and costs that cannot. A medical-versus-adult-use distinction would add a second line running the other direction, and shared costs would sit at the intersection of both. Rent for a building housing three functions, a security contract covering one vault used by two programs, a payroll for staff who move between counters, management compensation covering the whole enterprise, shared software licenses, one insurance program, and professional services billed to the entity rather than the activity are all examples that resist a single obvious answer.

What makes an allocation defensible is not its elegance but its evidence: a written policy adopted before the period, a basis tied to something measurable, consistent application, and workpapers that a reviewer can follow from source document to ledger balance. Nothing here promises deductibility of any expense. Allocation determines how a cost is presented and supported; whether it is deductible is a matter of law that remains unresolved for the activity split discussed in this guide.

• Rent and occupancy, allocated on measured space by use rather than a single annual estimate
• Payroll and labor, supported by time records that reflect actual activity
• Management and executive compensation, with a documented basis for any split
• Security, allocated by the area or function protected
• Utilities, using submeters or metered proxies where they exist
• Software and technology, allocated by seats, modules, or the function served
• Insurance, allocated by the coverage basis in the policy itself
• Professional services, with engagement scopes that identify the activity served where practical
• Shared facilities and equipment, with usage logs supporting the driver chosen

Chart of Accounts After Schedule III

A chart of accounts built when 280E applied uniformly usually optimizes for one thing: separating what goes into inventory from what does not. That remains necessary. What may need to be added is a second axis capable of distinguishing activities, so that the same ledger can produce either a combined or a segmented picture without a rebuild. Most accounting systems already support this through classes, departments, and locations, which means the change is usually a design and discipline exercise rather than a migration. Our New York cannabis accounting guide covers the underlying general ledger architecture in detail.

• Medical revenue and adult-use revenue as separate accounts or dimensioned streams
• Inventory by stage and by the activity it is destined to serve
• Cost of goods sold mapped to the same dimensions as revenue
• Payroll and labor accounts capable of carrying an activity dimension
• Shared overhead pools that are visible as pools rather than buried in operating expense
• Departments for dispensing, retail, cultivation, processing, and administration
• Classes for medical and adult-use activity applied consistently at entry
• Locations where an operator runs more than one facility
• Monthly reconciliations tied to each dimension, not only to the entity total
• Supporting workpapers stored with the period they belong to

Inventory and COGS Still Matter

If federal treatment loosens, the instinct will be to treat inventory accounting as less important. The opposite is closer to true. Cost of goods sold determines gross profit under any tax regime, it drives the state computation, it is the figure lenders and investors test first, and it is the area where cannabis examinations have historically concentrated. A change in the deductibility of operating expenses would not make an unsupported inventory balance defensible. Batch costing, standard-to-actual variance, shrink documented against BioTrack, and a monthly inventory rollforward remain the core of cannabis accounting in New York, and for retailers specifically, of dispensary accounting.

• Perpetual inventory maintained during the period rather than derived at year end
• Physical counts reconciled to BioTrack and to the ledger, with variances explained
• Costing policy documented in writing and applied consistently
• Shrink, waste, and destruction supported by state-required records
• Intercompany and interbranch transfers costed at a documented basis

Documentation and Audit Defense

A changing federal tax environment makes clean accounting more important, not less. Periods of transition generate positions taken under uncertainty, and positions taken under uncertainty are examined more closely than routine ones. The operator who can produce a coherent evidentiary chain, from register tape to seed-to-sale record to ledger entry to allocation workpaper to filed return, is in a different position from the operator who can produce a summary. Our audit preparation guide covers how that file should be assembled and retained.

• Point-of-sale reports by day, by register, and by activity
• BioTrack seed-to-sale records tied to the corresponding financial entries
• Payroll registers and time records supporting any labor allocation
• Vendor invoices retained with the coding rationale where a split was applied
• Inventory counts, rollforwards, and variance explanations
• Allocation workpapers showing the driver, the data, and the calculation
• Written accounting policies adopted before the period they govern
• Supporting schedules that tie to the financial statements
• Bank, merchant, and cash reconciliations completed monthly

What New York Cannabis Businesses Should Do Now

The practical answer for New York operators is to build optionality into the accounting without taking an unsupported tax position. Everything below is ordinary good practice that costs nothing in tax risk and preserves the ability to act quickly if federal guidance changes. It is also work that is far cheaper to do prospectively than to reconstruct. Operators in New York City and across the state face the same accounting question regardless of market size, and the preparation is the same.

• Keep the books current and closed monthly rather than catching up quarterly
• Separate medical and adult-use activity in the ledger where both genuinely exist
• Configure the point-of-sale system so activity segmentation is captured at the transaction, not after
• Reconcile inventory to BioTrack and to the ledger every month and document variances
• Adopt a written policy for shared costs and apply it consistently from the start of a period
• Capture allocation drivers now: square footage by use, employee time by activity, unit volumes, metered utilities
• Maintain payroll records detailed enough to support an activity split if one becomes relevant
• Preserve source documentation rather than summaries, and store it by period
• Model both outcomes for cash planning without filing on the more favorable one
• Plan for implementation: know what your system would need to change if guidance arrives mid-year

Questions New York Cannabis Operators Should Ask Their CPA

These are the questions worth raising at the next planning conversation. They are diagnostic rather than rhetorical: the answers reveal whether the accounting system could support a different federal treatment if one arrives, and where the gaps are while they can still be fixed. If any answer is uncertain, that is the starting point for the work rather than a reason to wait.

• Does Section 280E currently apply to all of our activity, and how are we filing on that basis?
• Can our accounting system distinguish medical activity from adult-use activity today?
• How are shared expenses tracked right now, and is the basis written down anywhere?
• Is payroll tracked by actual activity where employees work across both sides of the business?
• Can our inventory balances and cost of goods sold be substantiated from source records?
• Do our point-of-sale, BioTrack, and accounting records reconcile without manual adjustment?
• What documentation supports our current expense classification and costing treatment?
• What would we have to change in the ledger if federal guidance appears mid-year?
• How are we handling the divergence between the New York and federal computations?
