How to Start a Cannabis Business in Maine: Office of Cannabis Policy Three-Step License, Town Opt-In, 14% Sales Tax and the Residency Rule That Was Repealed
How to Start a Cannabis Business in Maine: Office of Cannabis Policy Three-Step License, Town Opt-In, 14% Sales Tax and the Residency Rule That Was Repealed
If you want to know how to start a cannabis dispensary business in Maine, understand that the process runs on two tracks at once. The first is the state license from the Office of Cannabis Policy (OCP), which controls who may hold a license and how the business must operate. The second is local. The town or city where you plan to operate must already allow your license type, and it must approve your specific location. If either track stalls, the rest of your plan stalls with it.
Informational only. This article is general information, not legal or tax advice. Cannabis is regulated differently under Maine and federal law, and both change over time. Before you sign a lease, buy equipment, or file a state application, talk with a Maine attorney who handles cannabis licensing and a CPA who understands cannabis tax issues.
What You Need Before You Apply
Gather these materials before you file anything, because most of them feed into the OCP application or the town request:
- A Maine entity. An LLC files a Certificate of Formation (Form MLLC-6). A corporation files Articles of Incorporation (Form MBCA-6).
- A compliant legal name. An LLC name must include “limited liability company,” “limited company,” “L.L.C.,” “LLC,” “L.C.,” or “LC” under 31 MRSA 1508.
- A registered agent with a physical Maine street address (for a noncommercial agent) or a listed commercial agent with a CRA public number.
- A criminal history check for every principal. OCP requires one for each person with an ownership or control role, so line these up early.
- The OCP application fee. Statutory ceilings are $250 for a store or products manufacturing application and $100 for a Tier 1 cultivation application. The actual amounts come from OCP’s current rule set.
- A specific premises address you can check against the school buffer and the town’s zoning and ordinance rules before you sign anything.
- A facility plan, which you file in Step 3, and a Maine Revenue Services sales tax registration.
Form Your Entity in Maine
Start with the entity, because OCP needs it. Maine has no general statewide business license, but forming an LLC or corporation is a filing with the Secretary of State, not a license. An LLC filing costs $175 and a corporation filing costs $145. Maine does not accept online formation filings. Print the fillable PDF, complete it, and mail or deliver it with payment. The Secretary of State currently lists 2 to 7 business days for corporate filings, but it treats that figure as variable, so confirm before you plan around it.
If you need a faster result, expedited handling is available under Secretary of State Rule 29-250 Chapter 200. 24 Hour Service costs $50 per request, and Immediate Service, completed at the time of the request, costs $100 per request. Availability depends on staffing, and the Bureau notes delays when expedited volume is high.
Reserve your name if you need time. Form MLLC-1 holds a name for 120 days and costs $20. Every Maine LLC and corporation must also keep a registered agent. A noncommercial agent needs a physical Maine street address, not a P.O. Box. The agent must consent to serve, and that consent is certified on the formation document under 5 MRSA 105.2. If you operate under a trade name, file Form ASUM-5 with the Secretary of State for $125.
The Residency Rule That Was Repealed
Maine once required cannabis business owners to be Maine residents. Public Law 2023, chapter 679 repealed that residency requirement. The business entity itself must still be formed in Maine under 28-B MRSA 202(3). Owners who live outside Maine may be able to participate, but you cannot simply use an entity formed in another state. If you already have an out of state company, ask OCP and your attorney how the formation rule applies to it before you file.
Caregiver rules also changed. Amendments under Public Laws 2025, chapters 512 and 514 took effect July 29, 2026. If your plan involves caregiver activity, confirm with OCP what applies to you.
Step 1: Apply to the Office of Cannabis Policy
Submit your OCP application with the application fee and the criminal history check for every principal. OCP must either issue a conditional license or deny the application within 90 days (28-B MRSA 205(3)). A conditional license is valid for one year and cannot be renewed. Treat it as one stage of the process, not as permission to open.
Before you file, confirm the location against the school buffer. A store may not sit within 1,000 feet of a school, unless the town sets a shorter distance of 500 to 999 feet (402(2)). Towns set their own distance within that range, so ask the municipal office which number applies to your address. A location that looks fine on a map can fail once the town’s measurement is applied.
Step 2: Request Local Authorization From the Town
With your conditional license in hand, request local authorization from the city, town or plantation where the premises sits (402(1)). The municipality must already have adopted an ordinance or warrant article allowing your license type. If it has not, it cannot authorize you, and no amount of paperwork changes that. Maine has 482 organized municipalities: 23 cities, 430 towns and 29 plantations. Counties license nothing for ordinary businesses, so the decision belongs to your municipality.
Ask the municipal clerk or officers, in writing, four questions: whether your license type is allowed; the local application form and fee; the school buffer distance the town has set; and what the local review process involves. Local fees and caps vary widely by town, so do not assume one town’s numbers apply to another. Confirm each number with the town directly.
Track the clock carefully. A town that does not act within 90 days is treated as denying your request. If the town gives written notice, that period extends to 180 days (402(5)). Submit your request in a way that proves the date you sent it, and put both deadlines on your calendar.
Step 3: Pay, File, Register and Activate
After local authorization, complete three tasks. First, pay the license fee. The statutory ceiling is $2,500 (28-B MRSA 207), and OCP’s rule set sets the actual amount. Second, file your facility plan with OCP. Third, register with Maine Revenue Services for sales tax. When these are complete, the active license is issued. It is valid for one year (205(4) and 208).
Sales tax is the step most people underbudget. Adult-use cannabis sales carry a 14% tax from January 1, 2026, up from 10% before that date (36 MRSA 1811). Register through Maine Revenue Services, and confirm with the agency how the rate is collected and reported. Do not build your price model around the 5.5% general state sales tax rate for these sales.
Step 4: Stay Current After Licensing
Your entity filings continue after you open. The LLC annual report (Form MLLC-13) costs $85 and is due June 1 each year. The first report is due between January 1 and June 1 of the year after formation. Corporations file Form MBCA-13 for the same $85 on the same schedule. You can file through Annual Report Online, which Maine runs through InforME, or by mail.
Tax structure matters. Maine has no LLC franchise tax and no separate LLC annual tax. An LLC is taxed by default as a pass-through, so its members report income on Maine individual returns at rates from 5.8% to 7.15%. For tax years beginning on or after January 1, 2026, a 2% surcharge applies to Maine taxable income above $1,000,000 for single filers, $750,000 for married filing separately, and $1,500,000 for married filing jointly or head of household. An LLC that elects corporate treatment pays Maine corporate income tax at 3.5% to 8.93%. Federal tax treatment of cannabis businesses differs from ordinary businesses, so get CPA advice before you choose a structure.

Common Mistakes to Avoid
- Forming the entity in another state. The residency repeal did not remove the Maine formation requirement under 202(3).
- Signing a lease before the town confirms the license type. If the municipality has not adopted an ordinance or warrant article for your activity, the lease may sit unused.
- Assuming retail approval covers cultivation or manufacturing. Each license type needs its own authorization, so confirm each one separately.
- Ignoring the 90 and 180 day clocks. A town that does not act is treated as denying. Track every submission date.
- Treating the conditional license as a final permit. It is valid for one year and cannot be renewed, and it does not let you open.
- Trying to file formation documents online. Maine requires printed forms, mailed or delivered with payment.
- Missing the June 1 annual report. The $85 fee is small, but late filings create avoidable problems with your entity standing.
- Budgeting at the wrong sales tax rate. Model adult-use sales at 14%, and confirm the collection mechanics with Maine Revenue Services.
- Assuming a town fee is the same everywhere. Fees and caps vary by municipality, so ask each one.
What to Expect: Realistic Results
Plan for several clocks to run at once: OCP’s 90 day decision window, the town’s 90 or 180 day window, and the time needed to build out the premises. If each agency moves on schedule, the process may take several months. None of these timelines is guaranteed, and a single incomplete filing can restart a clock.
Business results depend on your local market, competition, staffing, and product mix. Treat any revenue projection, including ones in this article or elsewhere, as a planning assumption to test, not a promise.
Product and marketing claims need careful review. FDA has not approved cannabis for most medical uses, and it has warned sellers against unproven health claims. Describe your products by their characteristics, avoid language suggesting a product treats, prevents or cures a condition, and have counsel review labels and advertising before they go live. Confirm Maine’s labeling and advertising rules with OCP.
