A cannabis MSO structure is a group of related companies: a parent holding company, separate licensed operating subsidiaries in each state, and a central entity that provides shared services to all of them. The central entity, often called the management company, bills each licensee under a written management services agreement.
The design affects liability, financing, 280E exposure and audit scope. Here is how each piece works and what Schedule III changed in 2026.
QUICK ANSWER
A cannabis multi-state operator (MSO) usually has a parent holding company, one licensed operating subsidiary per state, and a central management entity that employs shared staff and charges the licensees fees under management services agreements. IP and real estate companies often sit alongside. Intercompany prices must meet the arm's-length standard of IRC Section 482, and management fees paid by an adult-use licensee remain nondeductible under 280E.
Cannabis MSO Structure: At a Glance
- Licenses stay local: Each state license sits in its own subsidiary, and regulators review ownership changes.
- Central entity: One company employs shared staff and bills the licensees under a management services agreement.
- Tax limits: Section 482 requires arm's-length pricing, and 280E still blocks most adult-use deductions.
- Accounting: Management agreements that give control can force consolidation of a licensee as a variable interest entity under ASC 810.

What Is a Cannabis MSO Structure?
Federal law still treats adult-use marijuana as a Schedule I controlled substance, so no license travels across state lines. A company that operates in five states holds five or more separate sets of state licenses. Each set lives in a subsidiary formed for that state.
The MSO structure ties those subsidiaries together. It lets one leadership team run many markets while each licensee stays a separate legal and regulatory unit. The table shows the entities you will see most often.
▶ Typical MSO Entities
| Entity | Main role | Touches the plant? |
|---|---|---|
| Parent holding company | Owns the subsidiaries, raises capital, holds the debt | No |
| State operating subsidiary | Holds one state's licenses; cultivates, processes or sells | Yes |
| Central management entity | Employs shared staff; bills fees under a management services agreement | No |
| IP holding company | Owns brands, formulations and trademarks; licenses them for royalties | No |
| Real estate holdco | Owns or master-leases facilities; collects rent | No |
The Building Blocks of an MSO
Parent Holding Company
The parent sits at the top. It raises equity and debt, holds the subsidiaries' shares or membership interests, and often reports to public investors. Many large MSOs list in Canada. Their top company may be foreign, with a US holding company beneath it.
State-Licensed Operating Subsidiaries
These entities hold the cultivation, manufacturing and retail licenses. Regulators approve their owners, so you cannot freely move shares around the group. In California, for example, new owners must notify the Department of Cannabis Control within 14 days. A complete change of ownership needs an approved new license before the business operates under the new owners.
Central Management or Services Entity
The central entity employs the people who serve every state: executives, accounting, HR, IT, marketing and compliance. It signs a management services agreement with each licensee and charges a fee, often cost plus a markup. A well-run central entity never handles product.
IP and Real Estate Companies
An IP company owns brands, product formulas and trademarks, then licenses them to the licensees for a royalty. A real estate company owns or master-leases the buildings and collects rent. See our guide to IP royalty strategies under 280E for how royalty pricing works in practice.
Why MSOs Use a Central Entity
The first reason is liability. A regulatory or legal problem in one state stays inside that state's subsidiary. The second is financing: some lenders that avoid plant-touching companies will lend to a non-licensed management or real estate entity.
The third reason is efficiency. One finance team closes the books for every state, and one HR team runs payroll. Buyers also like clean structures, which matters in the cannabis M&A deals in 2026.
💬 The Conversation Worth Having
Ask your team one question: if the IRS asked tomorrow why each licensee pays its management fee, could you show the services, the hours and the pricing study? If the honest answer is no, fix the agreements before you fix anything else.

Section 280E denies deductions and credits to a trade or business that consists of trafficking in Schedule I or II substances. Only cost of goods sold survives. That rule drives a lot of MSO design, and also a lot of mistakes.
Fees Do Not Erase 280E
A management fee paid by an adult-use licensee is still that licensee's expense. Section 280E disallows it unless it properly belongs in inventory cost. The management company then reports the fee as income. Without care, the group pays tax on the same dollars twice.
What the Tax Court Has Said
Harborside (2018): The Tax Court found that the dispensary ran a single trafficking business. It also could not use Section 263A to push extra costs into inventory. The Ninth Circuit affirmed in 2021.
CHAMP (2007): The court allowed deductions for a genuinely separate caregiving business, allocated by staff time and floor space. Separate activity with its own substance can work.
Alternative Health Care Advocates (2018): A management company whose employees ran the dispensary's daily operations was itself trafficking, even without holding title to the marijuana. Its fees did not escape 280E.
Transfer Pricing: IRC 482 and Intercompany Agreements
Section 482 lets the IRS reallocate income and deductions among businesses under common control when needed to clearly reflect income. The regulations apply an arm's-length standard: would unrelated parties have agreed to the same price?
Expect the IRS to test management fees, royalties and rent between your entities. Each arrangement needs a signed agreement, a pricing method and evidence that the services or property changed hands. Large Section 482 adjustments can trigger Section 6662(e) penalties of 20% or 40%.
Documentation protects you only if it exists when you file the return. You must also produce it within 30 days of an IRS request during an exam.
Consolidated vs Separate Returns
A federal consolidated return needs an affiliated group of includible corporations: the parent must own at least 80% of the vote and value of each member. S corporations, foreign corporations and LLCs taxed as partnerships cannot join. Many MSO groups therefore file a mix of returns.
Consolidation does not switch off 280E for the trafficking member. States add another layer. A central entity with staff in several states can create nexus in each one. States also differ on combined, unitary and separate filing. Many states also decouple from 280E. Our state and local tax planning team maps which entities file where.
Schedule III in 2026: What Changes for MSOs
State-licensed medical marijuana moved to Schedule III effective April 28, 2026, so 280E stops applying to medical-licensed activity from that date. Adult-use marijuana remains on Schedule I, and 280E still applies to it. Read more on what the April 2026 Schedule III order means for 280E.
For an MSO with both license types, the job now is clean segregation. Track revenue separately and document how you split medical and adult-use costs. Central entity fees should follow the same logic.
GAAP Consolidation: ASC 810 and VIEs
For financial statements, ASC 810 decides which entities the parent consolidates. When the parent cannot own a licensee directly, a management agreement may still give it control. The licensee may be a variable interest entity. If the parent can direct its most significant activities and absorbs its losses or benefits, the parent consolidates it as primary beneficiary.
Public cannabis companies have consolidated licensees this way based on management and operating agreements. Your auditor will read every agreement, so write them with both tax and GAAP outcomes in mind.
KEY TAKEAWAYS
- ›An MSO keeps each state's licenses in a separate subsidiary and runs shared services through a central management entity.
- ›Management fees, royalties and rent must meet the arm's-length standard of Section 482, with documentation ready when you file.
- ›Fees paid by an adult-use licensee stay nondeductible under 280E, and a management company that runs operations can be trafficking itself.
- ›Medical-licensed activity left 280E on April 28, 2026; adult-use activity did not.
- ›Management agreements can trigger VIE consolidation under ASC 810, so draft them for both tax and audit.
Frequently Asked Questions
Structure Basics
A central entity is the management or services company inside a multi-state operator. It usually employs the executive, finance, HR, IT and compliance staff. It then serves each state-licensed subsidiary under a written management services agreement. The licensed entities pay it a fee. The central entity does not hold a cannabis license and should not handle product. Its value comes from shared costs and cleaner financing. Its fees still need arm's-length pricing and real services behind them, or the IRS can reallocate the income.
Most multi-state operators use a parent holding company at the top. Beneath it sit separate operating subsidiaries that hold the cannabis licenses in each state, because licenses cannot cross state lines. Many MSOs add a management company for shared services, an IP company for brands, and a real estate company for facilities. Written intercompany agreements connect the entities, and state regulators usually review any change in who owns the licensed subsidiaries.
Tax and Schedule III
Not by themselves. A management fee paid by a plant-touching licensee is still an expense of that licensee, and 280E denies the deduction for adult-use activity. The fee also becomes taxable income to the management company. Courts have gone further: in Alternative Health Care Advocates, the Tax Court held that a management company whose staff ran a dispensary was itself trafficking. A central entity helps only when it runs genuinely separate activity, keeps its people away from product, and charges arm's-length prices.
Yes, if the entities qualify. A federal consolidated return requires an affiliated group: a common parent must hold at least 80% of each member's vote and value. S corporations, foreign corporations and entities taxed as partnerships cannot join. Many MSOs have a Canadian-listed or foreign parent, so the US group often consolidates under a US holding company instead. Section 280E still applies to the trafficking member's own deductions inside the group. States set their own combined or separate filing rules.
Partly. State-licensed medical marijuana moved to Schedule III effective April 28, 2026, so 280E no longer applies to medical-licensed activity from that date. Adult-use marijuana remains on Schedule I, so 280E still applies to adult-use sales. MSOs that run both now need clean books by license type and a defensible cost allocation. Liability protection, transfer pricing and consolidation still matter as much as before.
