Choosing the right cannabis entity structure is one of the highest-stakes decisions a multi-state operator (MSO) makes, because the wrong choice can compound the punishing effect of Internal Revenue Code Section 280E across every state where you do business. The question is rarely “C-corp or pass-through” in the abstract. It is how each structure interacts with 280E, with state-by-state tax conformity, and with the way capital and ownership flow across a multi-jurisdiction footprint.
Quick answer: For most multi-state cannabis operators, a C-corporation is the more defensible entity structure today, because it caps the federal rate on 280E-inflated taxable income at the flat 21 percent corporate rate and keeps the tax liability at the entity level instead of pushing phantom income onto owners’ personal returns. Pass-through entities (S-corporations and partnerships) can make sense for single-state or smaller operators who value loss flexibility and want to avoid corporate-level double taxation, but they expose owners to individual rates as high as 37 percent on income that 280E has already stripped of most deductions. The right answer depends on your footprint, your investor base, and whether your activities are plant-touching or ancillary.
Why 280E Drives the Entire Entity Decision
Section 280E, enacted in 1982, disallows deductions and credits for any business that consists of trafficking in Schedule I or Schedule II controlled substances. According to the IRS Taxpayer Advocate Service, a marijuana business cannot deduct ordinary operating expenses such as rent, marketing, and most wages, even when it operates in full compliance with state law.
There is one structural relief valve: 280E does not prohibit a cannabis business from reducing its gross receipts by its properly calculated cost of goods sold (COGS). That distinction is why a cultivator or manufacturer that can capitalize more costs into inventory under the relevant accounting rules often fares better than a pure retailer, whose deductible costs sit mostly below the gross-profit line where 280E bites hardest.
The practical result is that a cannabis business pays federal income tax on its gross profit, not its net income. The Taxpayer Advocate Service illustrates this with an example of a retailer that has $1,000,000 of gross revenue, $750,000 of COGS, and $200,000 of operating expenses that 280E renders nondeductible. That business owes tax on $250,000 of gross profit, producing roughly $75,000 of tax rather than the $15,000 it would owe if those operating expenses were deductible, a fivefold difference. Because 280E inflates taxable income before any entity-level choice is made, the entity structure question becomes: at what rate, and on whose return, does that inflated income get taxed?
A second consequence is that the inflated tax bill arrives whether or not the operator generated the cash to pay it. An operator deep in a build-out, with capital flowing into licenses and facilities rather than into distributable profit, can still owe federal tax computed on gross profit. The entity structure you select determines who absorbs that mismatch, and absorbing it at a predictable flat rate is often easier to model and finance than absorbing it at fluctuating individual rates.
C-Corporation: Capping the Rate on Inflated Income
A C-corporation pays federal income tax at a flat 21 percent rate at the entity level. For a 280E business, this is the central advantage. The disallowed deductions inflate taxable income no matter the structure, so the operator wants the lowest possible rate applied to that inflated base, and 21 percent is meaningfully lower than the top individual rate of 37 percent.
The classic objection to a C-corporation is double taxation: the entity pays tax on its income, and shareholders pay again on dividends. For many cannabis MSOs this concern is muted in practice, because the business is reinvesting earnings to fund expansion into new states rather than distributing dividends. If cash stays in the company to build out licenses, facilities, and working capital, the second layer of tax is deferred, and the effective cost of the C-corp structure falls.
The C-corporation also isolates the 280E liability at the entity level. Owners are not handed a Schedule K-1 reporting taxable income far larger than the cash they actually received, a phenomenon often called phantom income. For operators raising institutional capital, a C-corp is also frequently the structure investors expect, and it cleanly accommodates an unlimited number of shareholders and multiple stock classes. Pease Bell’s cannabis industry advisory team works through these trade-offs in the context of each operator’s growth and capital plans.
There is also a practical predictability benefit. A flat entity-level rate lets a finance team forecast the federal tax cost of 280E with a single number across the whole group, which simplifies lender covenants, investor models, and quarterly estimates. That predictability is part of why many growth-stage MSOs default to a C-corp even before they have settled their long-term distribution policy.
Pass-Through Entities: Flexibility With Personal-Rate Exposure
Pass-through entities, principally S-corporations and partnerships, do not pay federal income tax at the entity level. Instead, income, losses, deductions, and credits flow through to owners, who report them on their individual returns. The IRS S corporations page explains that S-corp shareholders report flow-through income on their personal returns and are taxed at their individual income tax rates, which avoids the double taxation of a C-corporation.
For a non-cannabis business, that single layer of tax is usually the win. For a 280E business it cuts both ways. The income flowing through has already been stripped of most deductions, so owners can face individual rates up to 37 percent on income they may never have received in cash. That phantom-income problem is the defining risk of running a plant-touching cannabis operation through a pass-through.
Pass-throughs do retain real advantages in the right facts. Losses can flow through to offset an owner’s other income, subject to basis and at-risk limits, which matters for early-stage operators not yet profitable. They also avoid entity-level tax on liquidation or sale in many cases. An S-corporation, however, carries strict eligibility limits: no more than 100 shareholders, a single class of stock, and no partnership, corporate, or non-resident-alien owners, restrictions that frequently disqualify an MSO with layered investor structures.
Partnerships are more flexible on ownership than S-corporations and can support multiple classes of interest and special allocations, which appeals to operators with varied investor terms. They still pass 280E-inflated income through to partners at individual rates, so they share the same phantom-income exposure. The choice among pass-through forms therefore turns less on the rate, which is the owner’s rate either way, and more on ownership flexibility and how losses and allocations need to move.
Entity Classification Mechanics MSOs Should Know
The starting point is the limited liability company, which is flexible precisely because federal tax classification is elective. Per the IRS LLC classification guidance, a domestic LLC with at least two members defaults to partnership treatment, and a single-member LLC defaults to a disregarded entity, but either can elect corporate treatment by filing Form 8832. An LLC taxed as a corporation can then elect S-corporation status by filing Form 2553 if it meets the eligibility tests.
This flexibility lets an MSO build a structure that fits its footprint without changing legal forms in every state. A common pattern is a parent C-corporation that owns state-level operating subsidiaries, each often an LLC, structured to respect each state’s residency, ownership, and licensing rules. The parent absorbs the 280E exposure at 21 percent while the subsidiaries hold the licenses.
Entity classification elections have timing rules. An election filed on Form 8832 generally cannot take effect more than 75 days before the filing date or more than 12 months after it, so structure changes must be planned ahead of a tax year rather than reconstructed afterward. Coordinating these elections with state filings and license transfers is where many operators need hands-on tax advisory support before the structure is locked in.
Multi-State Layering: One Structure, Many Tax Regimes
The “multi-state” part of the analysis adds a layer most single-state operators never face: state conformity to 280E. Some states fully conform to the federal code and disallow the same deductions; others have decoupled, allowing cannabis businesses to deduct ordinary expenses for state purposes even though they cannot federally. The entity structure interacts with each state regime differently, and a structure that minimizes federal tax can create state-level inefficiencies if it is not mapped jurisdiction by jurisdiction.
State residency and ownership rules for license holders further constrain the design. Many states require in-state ownership percentages or prohibit certain entity types from holding a license, which can force the use of separate state-level entities under a holding company rather than one consolidated operating entity. The federal classification election then has to be coordinated so the consolidated group still achieves the intended 21 percent ceiling on 280E income.
Ancillary businesses change the calculus entirely. Companies that do not touch the plant, such as real estate holding entities, management companies, technology providers, and IP licensors, are generally not subject to 280E because they are not trafficking in a controlled substance. Many MSOs deliberately separate plant-touching and ancillary functions into different entities so that the ancillary entities can deduct expenses normally, while documenting intercompany pricing carefully to withstand scrutiny. This separation is a planning tool, not a loophole, and it has to be supported by genuine business substance.
The Rescheduling Question and Why Structure Still Matters
The federal landscape is shifting. A December 2025 executive order directed the Department of Justice to complete the process of moving certain medical marijuana from Schedule I to Schedule III, and the DOJ later issued a final order rescheduling state-licensed medical marijuana and certain related products. Treasury and the IRS announced that they would issue guidance on the federal tax consequences, including the expectation that 280E would apply only to activities that still involve Schedule I or II substances. Rescheduling generally removes 280E as a bar to deductions for businesses that, as a result, no longer traffic in a Schedule I or II substance.
The relief is partial, not universal. Under the announced framework, unlicensed and bulk marijuana, along with adult-use, or recreational, cannabis, remain on Schedule I and remain subject to 280E. An MSO with a mix of medical and adult-use operations across multiple states may find 280E lifting for some lines of business while continuing to apply to others, which makes a clean, well-segmented entity structure more valuable, not less.
Because the guidance, transition rules, and effective dates are still developing, operators should treat any rescheduling benefit as something to plan for rather than assume. A structure built to cap and isolate 280E exposure today remains protective if rescheduling is delayed, narrowed, or litigated, and it can be unwound or simplified if relief becomes broad and durable.
Frequently Asked Questions
Is a C-corporation always better than a pass-through for a cannabis business?
No. A C-corporation usually wins for profitable, capital-raising multi-state operators because it caps federal tax on 280E-inflated income at 21 percent and keeps the liability off owners’ personal returns. A pass-through can be better for early-stage or single-state operators who want losses to flow through and who plan to distribute most earnings. The answer depends on profitability, distribution plans, and investor structure.
Can a cannabis business deduct any expenses under 280E?
Yes, but only through cost of goods sold. Section 280E disallows ordinary business deductions, yet it does not prevent a cannabis business from reducing gross receipts by its properly calculated COGS. Cultivators and manufacturers can typically capitalize more costs into inventory than retailers can, which is why the activity type within your entity structure affects the effective tax burden.
Does separating plant-touching and ancillary businesses help with 280E?
It can. Entities that do not touch the plant, such as management, real estate, IP, or technology companies, are generally not trafficking in a controlled substance and so are not subject to 280E. Housing those functions in separate entities lets them deduct expenses normally, provided the separation reflects real business substance and intercompany charges are priced at arm’s length.
How does rescheduling change the entity structure decision?
Rescheduling of certain medical marijuana to Schedule III generally removes 280E for affected businesses, but unlicensed, bulk, and adult-use marijuana are slated to remain on Schedule I and subject to 280E. Because guidance and effective dates are still developing, a structure that isolates 280E exposure remains prudent. It protects you if relief is delayed and can be simplified later if relief proves broad.
Cannabis entity structure is not a one-time filing decision. It is an ongoing strategy that has to track 280E, state conformity, licensing rules, and a moving federal scheduling picture. Pease Bell CPAs helps multi-state operators model these trade-offs and build structures that hold up under audit and adapt as the rules change.
