Does 280E Still Apply in 2026?
Short answer: Nevada cannabis operators should continue to assume Section 280E applies to their federal returns unless and until their own tax advisor concludes, on the specific facts of their business and the law in effect for the year being filed, that some or all of their activity falls outside it. Federal cannabis scheduling has been an active policy question, and a move of cannabis out of Schedule I would remove the literal trigger in Section 280E, which by its terms applies to trafficking in a Schedule I or Schedule II controlled substance. That is the mechanism people are describing when they say rescheduling 'ends 280E.'
What is not established is the practical part: how any change applies to a particular tax year, how it interacts with returns already filed, whether refund claims for prior years are viable, and how Treasury and the IRS will expect taxpayers to substantiate deductions that were previously disallowed. Those questions require published guidance, and until that guidance exists, they are unresolved. We say that plainly rather than presenting a favorable reading as settled law.
The important accounting conclusion is the same either way. Whether 280E applies fully, partially, or not at all to a given Nevada operator, the deciding factor in an examination will be whether the books can substantiate the numbers on the return. A business that cannot separate revenue streams, cannot tie inventory to METRC activity, and cannot show how shared costs were allocated is in a weak position under any version of federal law. Our commercial engagement for this work is 280E tax planning and accounting.
- Established: 280E disallows ordinary deductions for businesses trafficking in Schedule I or II substances; only cost of goods sold survives.
- Changed: federal scheduling policy is in motion, and the statutory trigger for 280E is tied to that schedule.
- Unresolved: effective dates, treatment of prior years, amended-return and refund posture, and any substantiation expectations Treasury or the IRS may set.
- Unchanged: inventory, COGS, reconciliations and documentation determine whether a return can be defended.
Medical vs. Adult-Use Cannabis: Why the Difference Matters for 280E
Section 280E has never distinguished between medical and adult-use cannabis, because federal law never recognized the state-level distinction in the first place. What makes the question live in 2026 is that if federal treatment of cannabis changes, it may not change identically for every category of activity, and operators are reasonably asking whether medical and adult-use lines could end up on different sides of a federal tax rule. Whether any such distinction will exist is unresolved.
Nevada is a state where that question has real operational weight. Nevada has run a medical cannabis program since voters approved it in 2000, with dispensary sales beginning in the mid-2010s, and an adult-use market that opened in 2017 following Question 2. Most Nevada retailers hold both medical and adult-use retail licenses and serve both customer types from the same sales floor, the same inventory, and the same staff. The Cannabis Compliance Board licenses these establishments, and the Nevada Department of Taxation administers the excise taxes that already treat the two channels differently.
That existing Nevada tax difference is the practical hook. Nevada's 15% wholesale excise tax applies to the first wholesale transfer of cannabis regardless of eventual channel, while the 10% retail excise tax applies to adult-use retail sales and not to sales to registered medical cardholders. Nevada retailers therefore already have a business reason to distinguish medical from adult-use transactions at the point of sale. Operators whose systems make that distinction cleanly today are far better positioned than operators who track it only well enough to file an excise return, because a federal distinction, if one ever arrives, would demand a much more rigorous split all the way through the general ledger.
The Mixed-Use Cannabis Accounting Problem
Consider a Nevada retailer in Las Vegas holding both medical and adult-use certificates. It runs one 4,000 square foot location, twelve employees across retail and back-of-house, one security contract, one POS system, one METRC facility, and one lease. Roughly 12% of transactions are medical cardholder sales; the rest are adult-use. Today the operator files a 10% retail excise return on the adult-use portion and treats the whole business as one 280E taxpayer. If federal law ever treated those two revenue lines differently, this operator would need to divide essentially every cost in the business between them — and would need records supporting that division for the year in question, not records assembled after the fact.
Revenue is the easy part: a Nevada POS system that already flags medical cardholder transactions can produce segmented revenue with little rework. Direct costs are harder but tractable, because inventory is tracked at the package level in METRC and product sold to a medical patient can in principle be traced to its acquisition cost. The genuinely difficult category is shared cost: rent, utilities, security, insurance, software subscriptions, management salaries, professional fees, and the wages of budtenders who serve both customer types in the same shift.
There is no IRS-approved allocation methodology for splitting shared cannabis expenses between medical and adult-use activity, and we will not present one as though there were. What we can say is what makes any allocation defensible in an examination: it is based on an objective measure the business actually tracks, it is documented in writing before the return is filed, it is applied consistently across periods, and it can be recomputed from source records by someone who was not involved in preparing it.
- Segment revenue at the POS by medical cardholder vs. adult-use, and carry that segmentation into the general ledger rather than keeping it only in the POS.
- Use departments or classes for retail, cultivation, production and administration so costs land in a meaningful bucket before any allocation is attempted.
- Build a chart of accounts that separates direct product cost, direct labor, allocable facility cost, and clearly non-allocable selling and administrative cost.
- Track payroll by actual function and hours worked, not by job title, so labor allocation rests on records rather than estimates.
- Keep POS reports, METRC package histories and inventory counts reconciled monthly so that any allocation base can be substantiated from primary records.
- Document the allocation policy contemporaneously, including the reason each base was chosen.
Cannabis 280E Expense Allocation and Apportionment
Expense allocation is the accounting problem most likely to determine outcomes in the next several years, regardless of how federal scheduling resolves. Under current 280E practice the line that matters is between cost of goods sold and everything else. If federal treatment ever varies by activity type, a second line appears: between activity that receives one treatment and activity that receives another. Businesses that have already built a rigorous allocation discipline for the first line will find the second one manageable. Businesses that have not will be reconstructing years of records under time pressure.
Rent is the standard example. A Las Vegas dispensary with a single lease covering sales floor, vault, back-of-house inventory storage and office space already needs a square-footage schedule to support any inventory-related portion of occupancy cost. A Reno cultivator with flower rooms, veg space, drying and cure rooms, trim areas, and administrative offices needs the same schedule at greater granularity. Those schedules should come from a measured floor plan, not from a percentage someone chose because it felt reasonable.
Payroll is the highest-risk category because it is the largest cost in most cannabis operations and the easiest to allocate carelessly. A production technician who spends part of each week on packaging and part on inventory receiving is doing two different things for accounting purposes, and only a timekeeping system that captures function will support the split. Management compensation is harder still, because an owner-operator genuinely does divide time across production oversight, retail management, compliance and administration; a periodic documented time study is the usual answer, and it is worth far more than an after-the-fact estimate.
The remaining shared costs — utilities, security, insurance, seed-to-sale and POS software, accounting and legal fees, banking and armored car services — each need an allocation base tied to something measurable: metered consumption, camera or guard coverage by area, policy schedules, user licenses by department, or engagement scope. None of this promises deductibility. It establishes that whatever position the return takes, the numbers behind it came from records rather than judgment applied at filing time.
- Rent and occupancy — measured square footage by function, refreshed when the space is reconfigured.
- Payroll — hours by function from a timekeeping system, supplemented by documented time studies for management.
- Utilities — submeters where cultivation or production load is material; consumption-based estimates otherwise, documented.
- Security — coverage by area for guards and cameras rather than a flat split.
- Software and professional services — user counts, module scope, or engagement scope by department.
- Insurance — policy schedules that already identify covered property and operations.
Chart of Accounts After Schedule III
Most Nevada cannabis charts of accounts were built to answer one question: what is COGS and what is not. That is no longer sufficient planning. A chart of accounts built for 2026 and beyond should be able to answer several questions at once without restructuring: what did each activity earn, what did each activity cost directly, what shared costs were allocated to it and on what basis, and how does all of that tie back to inventory records.
In practice that means revenue accounts or classes that separate medical from adult-use retail sales and wholesale transfers; inventory accounts that separate raw materials, work in process and finished goods where the license type warrants it; COGS accounts that mirror the inventory structure so cost flows are traceable; labor accounts split by function rather than by department name alone; and a distinct group of shared overhead accounts that are never posted to directly from an invoice without a department or class tag.
Departments, classes and locations are the mechanism that keeps this from becoming an unmanageable account list. A multi-location Nevada group operating in Las Vegas, Henderson and Reno should not create parallel account trees per site; it should use location tagging against one account structure, so consolidated and site-level reporting come from the same ledger. Our cannabis accounting and cannabis bookkeeping engagements build and maintain exactly this structure, and the Nevada cannabis accounting guide walks through the underlying design.
- Medical and adult-use revenue separated in the ledger, not only in the POS.
- Inventory and COGS accounts that mirror each other so cost flow is traceable package to sale.
- Labor accounts by function: cultivation, production, packaging, receiving, retail, administration.
- Shared overhead accounts that require a department, class or location tag on every posting.
- Monthly reconciliation workpapers stored with the close package, not in someone's personal files.
Inventory and COGS Still Matter
It is tempting to read a favorable federal development as a reason to relax inventory discipline. The opposite is true. Cost of goods sold does not disappear if 280E stops applying; it simply stops being the only deduction available. Inventory remains the largest balance sheet item for most Nevada operators, it remains the basis for gross margin, and it remains the number most likely to be tested in an examination because it is the number most often wrong.
For a Nevada cultivator, this means capitalizing direct materials and direct cultivation labor plus an allocable share of facility cost into growing inventory, and moving cost through harvest, drying, cure and packaging with a consistent method. For a manufacturer, it means raw material, work in process and finished goods accounting with batch-level cost and documented yield and loss. For a retailer, it means invoice cost plus acquisition costs, with physical counts reconciled to both the ledger and METRC. The Nevada inventory accounting guide and our inventory accounting service cover the mechanics in depth.
Reconciliation is what makes any of it defensible. Package-level METRC activity, POS sales, physical counts and the general ledger should agree each month, with variances investigated and explained while the facts are still recoverable. A variance found eleven months later is an unexplained variance, and an unexplained variance in a cannabis inventory account is exactly what an examiner looks for.
Documentation and Audit Defense
A changing federal tax environment makes documentation more important, not less. Periods of legal transition produce returns filed under one understanding and examined under another, amended returns and refund claims that invite review, and positions that depend entirely on how well the underlying records were kept. The operators who come through that comfortably are the ones whose records were built during the year rather than assembled in response to a notice.
The record set that matters is not exotic. It is the ordinary output of a well-run accounting function, retained and organized: POS daily and periodic reports reconciled to deposits; METRC package histories and transfer manifests; physical inventory count sheets signed and dated; payroll registers with hours by function; vendor invoices matched to receiving records; bank and merchant reconciliations; allocation workpapers showing base, computation and result; a written accounting policy memo; and the supporting schedules that bridge the general ledger to each tax return filed.
Two habits raise the quality of that record set materially. First, write down the reason for each methodology choice at the time it is made — a paragraph explaining why square footage was chosen over headcount is worth more than the schedule itself. Second, keep methodology consistent between periods, and when a genuine business change requires a different approach, document the change and the reason for it. Unexplained year-over-year methodology shifts are among the most reliable ways to turn a routine review into a full examination. Our audit representation work starts from this record set.
- POS reports reconciled to deposits and to segmented revenue in the ledger
- METRC package histories, transfer manifests and adjustment logs
- Signed and dated physical inventory counts with variance explanations
- Payroll registers showing hours by function, plus documented time studies
- Allocation workpapers showing base, computation, result and rationale
- Written accounting policy memos and the schedules bridging the ledger to each return
What Nevada Cannabis Businesses Should Do Now
The right posture for a Nevada operator in 2026 is preparation, not repositioning. Nothing here supports taking an aggressive federal position in advance of guidance, and we do not recommend filing on the assumption that a favorable outcome is already law. What we do recommend is putting the accounting infrastructure in place so that whatever guidance eventually arrives can be implemented from existing records rather than from reconstruction.
For Nevada specifically, several items deserve attention now. Nevada retailers already distinguish medical cardholder sales for the 10% retail excise tax; that distinction should be verified as accurate transaction by transaction and carried into the general ledger rather than living only in the POS and the excise return. Nevada's 15% wholesale excise tax means cultivators and distributors need clean first-transfer records tied to METRC manifests. Nevada has no state income tax, so nothing about federal 280E affects a Nevada return, and no state-level relief is available or forthcoming — the entire exposure sits on the federal return, which is a reason to invest in federal-return substantiation specifically.
Operators with Commerce Tax exposure above the $4 million gross revenue threshold and Modified Business Tax obligations on wages should also confirm that the payroll and revenue detail supporting those Nevada filings is consistent with the detail supporting the federal return. Inconsistency between state and federal filings is an avoidable source of questions, and multi-entity Nevada groups are the most likely to have it. Groups operating across Las Vegas, Henderson and Reno should reconcile the entity map, the license map and the ledger structure to each other at least annually.
- Verify medical vs. adult-use transaction coding at the POS and carry it into the ledger.
- Reconcile METRC, POS, physical counts and the general ledger monthly, with variances explained in the period.
- Move payroll to function-based time capture; document a time study for management compensation.
- Write allocation policies for rent, utilities, security, software, insurance and professional fees, with the base and rationale stated.
- Preserve source documentation in an organized, retrievable structure rather than in scattered folders.
- Confirm Nevada excise, Commerce Tax and Modified Business Tax detail is consistent with federal return detail.
- Plan for implementation: identify which reports and schedules you would need to produce quickly if federal guidance changed the treatment of your activity.
Questions Nevada Cannabis Operators Should Ask Their CPA
The conversation to have with your accountant this year is not 'is 280E gone.' It is whether your accounting system could support a different federal treatment if one arrived, and whether the records behind the current return would hold up if examined. The questions below are the ones that produce useful answers.
If your current advisor cannot answer these from your existing records, that is the finding. It is not a reason to change tax positions; it is a reason to change accounting practices. You can bring these questions to a consultation or reach us at the phone number and email in the site header.
- Does 280E currently apply to all of our activity, and on what analysis?
- Can our accounting system distinguish medical from adult-use activity in the general ledger, not just in the POS?
- How are shared expenses currently tracked, and what allocation base supports each one?
- Is payroll captured by actual function and hours, or only by job title and department?
- Can inventory and COGS be substantiated from METRC, purchase records and physical counts?
- Do POS, seed-to-sale and accounting records reconcile monthly, and where do they currently disagree?
- What written documentation supports our current accounting treatment?
- What accounting changes would we need to make if additional federal guidance changed the treatment of our activity, and how quickly could we make them?
