Cannabis Entity Structure: LLC, S-Corp, or C-Corp Under 280E?

Entity selection for a cannabis business does not follow the same playbook as for a restaurant, a law firm, or a construction company. The reason is IRC 280E, the provision that bars any deduction or credit for amounts paid or incurred in carrying on a trade or business that consists of trafficking in a controlled substance. As of this writing, marijuana remains a Schedule I controlled substance under the Controlled Substances Act, and no rescheduling or legalization proposal has been enacted into federal law. That means 280E is fully in effect, and it changes the math on every entity-structure question a cannabis operator will face. The standard advice to “just elect S-corp” can actually make things worse. A C-corp, which is almost never the right answer in other industries, deserves serious evaluation. And the multi-entity strategy that most cannabis tax advisors recommend is not clever structuring for its own sake; it is a direct response to the way 280E warps the economics. For a deeper look at what 280E actually disallows, start with our 280E deduction limitation guide.

Why does 280E change the entity analysis?

Because 280E eliminates the deductions that normally drive entity selection decisions. In any other business, the choice between LLC, S-corp, and C-corp hinges on self-employment tax, reasonable salary, distribution flexibility, and the qualified business income (QBI) deduction under IRC 199A. Those factors assume you can deduct your operating expenses. A restaurant that grosses $2 million and spends $1.6 million on rent, payroll, marketing, insurance, and supplies has $400,000 in taxable income. The entity question is about how that $400,000 gets taxed.

A cannabis dispensary that grosses $2 million and has the same $1.6 million in expenses does not get to deduct most of them. 280E allows only the cost of goods sold (COGS), not ordinary business deductions. If COGS is $800,000, the dispensary’s taxable income is $1.2 million, not $400,000, even though the actual cash profit is the same $400,000. The entity question is now about how that inflated $1.2 million gets taxed, and the answers are very different.

The QBI deduction under IRC 199A does not apply to any trade or business involving the sale of a Schedule I or II controlled substance. Cannabis is Schedule I. So the 20% pass-through deduction that makes S-corps and partnerships attractive in other industries is off the table entirely.

What happens if I use an S-corp for a cannabis business?

The S-corp is the default recommendation for most profitable businesses, and for good reason in normal circumstances. The owner pays FICA on a reasonable salary and takes the remaining profit as distributions free of self-employment tax. In a typical business with $300,000 in net income, the FICA savings alone can exceed $15,000 per year.

For cannabis, the S-corp introduces a problem that does not exist in other industries. An S-corp is a pass-through entity: the income, deductions, and credits flow through to the shareholder’s personal return. Under 280E, most deductions are disallowed at the entity level. That means the shareholder receives a K-1 showing a large taxable income figure (revenue minus only COGS) with no offsetting business deductions. The shareholder pays personal income tax on that inflated figure at their marginal rate, which can reach 37% federally plus state tax.

Here is where it gets worse. If the S-corp has a losing year on a cash basis (because operating expenses consumed all the cash, even though they are not deductible), the shareholder cannot use that loss to offset other income. The loss does not pass through in a usable form because 280E has already stripped the deductions that would have created the loss. The shareholder may owe tax on K-1 income that exceeds the actual cash distributions received. That is a phantom income problem that does not arise in non-cannabis S-corps.

The reasonable salary requirement adds another layer. The IRS requires that an S-corp shareholder who performs services receive reasonable compensation before distributions. That salary is subject to FICA (both employer and employee shares). In a 280E business, the salary is not deductible by the entity (unless it qualifies as part of COGS, which officer compensation rarely does). So the S-corp is paying a salary that generates FICA liability but produces no tax deduction. The FICA savings strategy that makes S-corps attractive in every other industry can actually increase the total tax burden in cannabis.

Is a C-corp better for cannabis?

It can be, depending on the numbers. A C-corp pays tax at its own level at a flat 21% rate under IRC 11. That 21% applies to the 280E-inflated income, so the effective rate on actual economic profit is much higher than 21%. But it is still a known, flat number, and for owners whose personal marginal rate would exceed 21% (which includes anyone in the 24% bracket and above, before state taxes), the entity-level rate is lower than the pass-through rate.

The catch is double taxation. When the C-corp distributes profits to shareholders, those distributions are taxed as qualified dividends at the shareholder level (0%, 15%, or 20%, plus the 3.8% net investment income tax above the threshold). The combined rate (21% corporate plus roughly 23.8% on the dividend) can exceed 40%. That combined rate may still be competitive with the pass-through rate on 280E-inflated income at higher brackets, but it requires modeling with actual numbers.

A C-corp also gives the owner the ability to retain earnings inside the entity at 21% and defer the shareholder-level tax. In a growth phase where the business needs to reinvest every dollar, this deferral has real value. The accumulated earnings tax under IRC 531 can apply if retained earnings exceed reasonable business needs, but cannabis businesses with expansion plans, regulatory compliance costs, and working capital demands can typically justify substantial retained earnings.

The hypothetical illustrates why C-corps deserve a second look in cannabis, but the outcome is highly sensitive to the COGS ratio, the owner’s other income, and the state tax regime. States that conform to 280E make the analysis harsher; states that decouple from 280E for state income tax purposes can shift the balance.

What about an LLC taxed as a partnership?

An LLC taxed as a partnership (the default for multi-member LLCs) passes all income, deductions, and credits through to the owners on Schedule K-1, just like an S-corp. The 280E problem is similar: operating expenses are disallowed, so the K-1 shows inflated income. But there are two differences that matter.

First, partnership allocations are more flexible than S-corp distributions. An S-corp must allocate income strictly by share ownership (one class of stock). A partnership can use special allocations under IRC 704(b) to direct income, deductions, and COGS-related items to specific partners, as long as the allocations have substantial economic effect. This flexibility can be valuable in cannabis ventures with multiple owners who have different tax profiles.

Second, a single-member LLC (disregarded entity) reports directly on the owner’s Schedule C, which means the full 280E-adjusted income is subject to self-employment tax under IRC 1402. A general partner in a multi-member LLC also faces SE tax on their share of trade or business income. There is no reasonable salary cap to limit the SE tax exposure the way there would be in an S-corp, but in cannabis, the S-corp salary is not deductible anyway, so the comparison is not as simple as “S-corp always saves on SE tax.”

The pass-through treatment means that if an owner has losses from other activities or other sources of income that can absorb the high effective rate, the partnership form gives the owner’s return more flexibility than a C-corp structure, where the income is locked inside the entity at 21% regardless of the owner’s overall situation.

Can a multi-entity structure help?

This is where most cannabis tax planning concentrates, and for good reason. 280E applies only to businesses that “consist of trafficking in controlled substances.” A business that does not touch the plant is not subject to 280E. That creates an opportunity to separate plant-touching activities from everything else.

A typical multi-entity structure for a vertically integrated cannabis operation looks like this:

• Entity A (plant-touching): Holds the cannabis license. Cultivates, processes, or sells marijuana. This entity is subject to 280E. It should be structured to maximize COGS (since COGS is the only deduction available) and minimize non-COGS expenses.
• Entity B (management company): Provides management services, administrative support, marketing, HR, and accounting to Entity A. Entity B is not trafficking in a controlled substance; it is providing management services. Entity B can deduct its ordinary business expenses normally.
• Entity C (real estate): Owns the real estate and leases it to Entity A. Rental income is not trafficking income. Entity C deducts depreciation, property taxes, insurance, and mortgage interest normally.

Entity A pays management fees to Entity B and rent to Entity C. Those payments are not deductible by Entity A (because 280E disallows them), but they are income to Entity B and Entity C, where they are offset by legitimate, fully deductible expenses. The net effect is that a portion of the economic activity is taxed in entities where normal deduction rules apply.

The IRS is aware of this structure and has challenged it in several Tax Court cases. The key to defensibility is that the fees must be at arm’s length (reflecting actual fair market value for the services or space provided), the entities must have genuine economic substance, and Entity B must actually perform the services it bills for. A management company that has no employees, no office, and no function other than receiving fees from the licensed entity will not survive scrutiny.

How does entity choice affect state taxes?

State conformity to 280E varies widely, and the state tax picture can rival or exceed the federal impact. Some states (California, for example) conform to 280E, meaning the state income tax also applies to the inflated, post-280E income figure. Other states have decoupled from 280E, allowing cannabis businesses to deduct operating expenses for state tax purposes even though they cannot for federal. The entity choice interacts with the state regime: a C-corp in a state that decouples from 280E for corporate income tax may see a significantly lower combined tax burden than a pass-through in a state that conforms.

State-by-state analysis is beyond the scope of this guide, but we cover the major state variations in our multistate cannabis tax guide. The short version: you cannot evaluate entity structure without knowing which states you operate in and whether those states follow 280E.

What about the QBI deduction?

It does not apply. IRC 199A(c)(4)(B) specifically excludes any trade or business involving the performance of services in the field of “any trade or business consisting of the sale of, or provision of services relating to, the use of controlled substances within the meaning of schedule I or II of the Controlled Substances Act.” Cannabis is Schedule I. The 20% qualified business income deduction is not available to cannabis businesses, regardless of entity type. This eliminates one of the primary reasons to operate as a pass-through entity.

What entity should a new cannabis business choose?

There is no universal answer, because the right structure depends on the owner’s full tax picture, including other sources of income, the state(s) of operation, the COGS ratio, growth plans, and how capital will be extracted from the business. But the framework for the decision is different from any other industry:

• If the owner’s personal marginal rate exceeds 21% and the business will retain earnings for growth, a C-corp reduces the current-year tax burden at the cost of eventual double taxation on distributions.
• If the owner has significant other income or losses that can interact with pass-through cannabis income, an LLC or partnership preserves flexibility on the personal return, even though the 280E-inflated income will be high.
• If the business is vertically integrated (cultivation, processing, and retail under one roof), a multi-entity structure is almost always worth the compliance cost. Separating management and real estate from the licensed operation moves taxable income into entities where normal deductions apply.
• The S-corp election, which is the default recommendation for nearly every other profitable business, should be evaluated with extreme caution in cannabis. The combination of non-deductible officer compensation, phantom income risk, and loss-trapping makes it the wrong choice more often than owners expect.

Every cannabis entity decision should be modeled with actual projected numbers, not rules of thumb. The effective tax rate on a cannabis business can range from under 30% to over 80% depending on the COGS ratio, entity structure, and state regime. Getting this wrong at formation is expensive to fix later, because changing entity types triggers tax consequences of its own (deemed liquidation, recapture, transfer of licenses that may require regulatory approval).
