How to Start a Seafood Business in Maine: Wholesale License $192.75, Retail Seafood License $100, Lobster Processor Up to $750 and the Commercial Fishing and Shellfish Licenses

If you plan to buy, sell, or process seafood in Maine, most of your licensing runs through the Maine Department of Marine Resources (DMR). This guide explains how to start a seafood dealer business in Maine in the order that causes the fewest problems: choose the license that fits your operation, form your entity, handle local and health requirements, then budget for recurring fees.

The first thing to understand is that Maine has no general statewide business license and no general town license. Registering an LLC, corporation, or assumed name is a filing, not a license. Your actual permissions come from licenses tied to specific activities. Where a figure is not published in the sources we checked, this guide says so and tells you which agency to contact.

Materials and Information You Need Before You Apply

Gather these items before you contact any agency. Nearly every application asks for the same information, and having it ready prevents delays.

• A proposed business name, checked against the Secretary of State business search
• A physical Maine address for your dock, plant, shack, or storefront
• A registered agent with a physical Maine street address, or a commercial registered agent
• Government-issued ID for each owner or member
• A federal employer identification number (EIN) from the IRS for banking and tax filings
• A list of vehicles and establishments, since supplemental licenses are counted per vehicle or per establishment
• A list of species you will buy, sell, or process, such as lobster, sea urchin, shrimp, clams, or finfish
• Funds for filing fees, license fees, and a reserve for your first annual report

Step 1: Match Your Operation to the Right License

Maine splits seafood licensing by what you do with the product. A dealer who buys from harvesters and resells needs a different license than a shack that sells cooked food to customers. Decide which activities apply before you pay any fee.

Activity	License	Fee
Buying seafood and reselling to other businesses (dealer)	Wholesale seafood license	$192.75
Each extra establishment or vehicle	Supplemental license	$38.25 each
Selling directly to consumers	Retail seafood license	$100
Enhanced retail activity (confirm eligibility with DMR)	Enhanced retail certificate	$100
Limited retail sales by a harvester	Limited retail seafood harvester certificate	$50
Processing lobster at one fixed place	Lobster processor license	Set by DMR rule, capped at $750 by statute
Commercial fishing	Commercial fishing license	$48 resident operator; $128 for operator and all crew
Harvesting shellfish	Commercial shellfish license	$58.25 resident; $67 if under 18 or 70 and older

The wholesale license is the one most dealers need. Under the same license, you can hold a lobster permit, a sea urchin buyer or processor permit, and a shrimp permit. You do not need a separate purchase for each of those.

Step 2: Choose Your Entity Type

Your entity determines which filings you make and how the business is taxed. A sole proprietorship or general partnership does not file formation documents with the Secretary of State. An LLC or corporation does.

• LLC: File the Certificate of Formation (Form MLLC-6) under 31 MRSA 1531. The filing fee is $175. By default, Maine taxes an LLC as a pass-through, so members report income on their Maine individual returns at graduated rates of 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, or $1,500,000 for married filing jointly or head of household.
• Corporation: File Articles of Incorporation (Form MBCA-6) under Title 13-C, the Maine Business Corporation Act. The filing fee is $145. A corporation pays Maine corporate income tax at graduated rates from 3.5% to 8.93%.

Maine has no LLC franchise tax and no separate LLC annual tax. The only recurring state filing charge for an LLC is the $85 annual report fee covered in Step 13. This is informational content, not tax advice. Ask a CPA which structure fits your boat, catch volume, and personal income before you file.

Step 3: Check and Reserve Your Name

An LLC name must contain "limited liability company," "limited company," or an accepted abbreviation such as "LLC," "L.L.C.," "LC," or "L.C." under 31 MRSA 1508. Search the Secretary of State database at apps3.web.maine.gov/nei-sos-icrs/ICRS before you commit to a name. If you need time to finish your paperwork, you can reserve the name for 120 days on Form MLLC-1 for $20. Download it from the Secretary of State form PDF.

Step 4: File Your Formation Documents

Maine does not offer online filing for formation documents. The LLC and corporation forms are fillable PDFs that you print, complete, and mail or deliver with payment to the Division of Corporations, UCC and Commissions. Start at the Secretary of State corporations and commissions page.

Processing times vary. The Secretary of State pages reviewed for this guide list 2 to 7 business days for corporate filings, but earlier snapshots showed longer waits, so treat that figure as variable. Expedited handling costs extra: 24 Hour Service is $50 per request, and Immediate Service, completed when the request is made, is $100 per request. Availability depends on staffing, and the Bureau notes delays during periods of high expedited volume.

Step 5: Appoint a Registered Agent

Every Maine LLC and corporation must appoint and maintain a registered agent under the Model Registered Agents Act, Title 5 chapter 6-A. The agent is either a commercial registered agent listed with the Secretary of State or a noncommercial agent. A noncommercial agent must provide a physical street address in Maine, not a P.O. Box, plus a mailing address if different. The agent must consent to serve, and that consent is certified on the formation document under 5 MRSA 105.2. If you change agents later, you file Form CLKRA-3 for $35.

Step 6: File an Assumed Name if You Will Use a Trade Name

If your business will operate under a name different from its legal name, you need an assumed name filing. The process depends on your entity:

• LLCs and corporations: File a Statement of Intention to do Business under an Assumed Name (Form ASUM-5) with the Secretary of State for $125.00.
• Sole proprietors and general partnerships: File a sworn assumed-name certificate with the clerk of the city or town where the business is carried on, under 31 MRSA 1. Municipal fees are set by each town and are not published by the state, so confirm the amount with the clerk.

Step 7: Check Local Requirements in Your Town

Maine issues no general statewide business license, and its general licenses to operate are managed by cities and towns. Each municipality licenses specific activities through its own ordinance, and fees vary widely from town to town. Waterfront use, mobile food sales, outdoor sales, and some dock or shore activities may fall under local rules, so contact your municipal office before you sign a lease or buy equipment. The state's free Business Answers service can help you identify which state and local permits apply to your activity.

Your local office is also the place to ask about town clam licenses and local shellfish conservation rules, which are covered in Step 10.

Step 8: Apply for the DMR Wholesale or Retail License

The wholesale seafood license costs $192.75 and is issued under 12 MRSA 6851. Each supplemental license costs $38.25 and covers an extra establishment or vehicle. If your trucks buy product from harvesters at several docks, count each vehicle carefully.

A retail seafood license costs $100 under 12 MRSA 6852. The same section lists the enhanced retail certificate at $100 and the limited retail seafood harvester certificate at $50. If you sell directly to consumers from a store or a truck, you need the retail license for that activity. The wholesale license authorizes buying and selling in the wholesale or retail trade, while the retail license covers a narrower set of retail activities, so confirm with DMR which license covers each of your sales.

Step 9: Plan for a Lobster Processor License if You Process Lobster

A lobster processor license is issued under 12 MRSA 6851-B for processing at one fixed place. The fee is set by DMR rule, and state law caps it at $750. Because the fee is set by rule, do not budget a specific number from this guide. Contact DMR Licensing for the current amount. Plan your location early, because the license is tied to one fixed place.

Step 10: Add Harvest Licenses if You Fish or Dig

If you or your crew harvest product, you need harvest licenses in addition to dealer licenses:

• Commercial fishing license: $48 for a resident operator, or $128 for an operator and all crew, under 12 MRSA 6501(5).
• Commercial shellfish license: $58.25 for residents, or $67 if you are under 18 or 70 and older, under 12 MRSA 6601.
• Town clam license and local rules: Many towns issue their own clam licenses and set conservation rules. Get those from the town office where you dig.

For lobster transportation, meat permits, and marine worm dealers, check with DMR Licensing for the current license and fee. Do not assume these are covered by the wholesale license.

Step 11: Address Food Safety and Health Licensing

Food rules apply to your product in addition to your DMR licenses. A lobster shack that serves food on site needs an eating place license from the Department of Health and Human Services Health Inspection Program. The Department of Agriculture, Conservation and Forestry licenses food processors, so if you cut, cook, pack, or further process product, contact that department about the processor license and its fee. Plan for inspections, and keep records of where your seafood came from and how you stored it. Federal food safety rules may also apply, including seafood safety requirements, so confirm them with the FDA and your state inspector.

Step 12: Register for Sales Tax Where It Applies

Maine's general sales tax rate is 5.5%. Prepared food and on-premises liquor are taxed at 8%. Whether raw seafood you sell is taxable depends on how it is sold and to whom, so confirm your treatment with Maine Revenue Services before you open. If you collect sales tax, apply through the Maine Revenue Services portal, and visit the Maine Revenue Services main page for current guidance.

Step 13: Calendar Your Annual Report

Every Maine LLC and corporation must file an annual report with the Secretary of State. The fee is $85. Reports are due June 1 each year. Your first report is due between January 1 and June 1 of the year after you form. LLCs file Form MLLC-13, and corporations file Form MBCA-13. You can file through the Annual Report Online system. Put the June 1 date in your calendar the day you form the entity.

Tips for Getting Licensed Faster

• Call DMR Licensing before you buy a truck or lease a dock. Confirm which license covers each vehicle and location.
• Keep a single spreadsheet with every license number, fee, renewal date, and the agency that issued it.
• Ask your town office and DMR whether a planned activity needs a permit before you start, not after.
• Use the Maine Small Business Development Centers for free advising on business plans and financing. The SBA Maine district page lists additional resources.
• Budget for the expedited filing fee only if you have a firm opening date. Otherwise, the standard timeline is fine.

Common Mistakes to Avoid

• Looking for a statewide business license. Maine does not issue one. Your permissions come from DMR, the health and food agencies, and your town.
• Undercounting vehicles and establishments. Each extra truck or location can require a $38.25 supplemental license.
• Using a P.O. box as your noncommercial registered agent address. The agent needs a physical street address in Maine.
• Treating the retail and wholesale licenses as interchangeable. They cover different activities.
• Forgetting the processor license is tied to one fixed place. Moving operations may require a new filing.
• Missing the June 1 annual report. Set a reminder for the day you file your formation documents.
• Skipping the town clam license. A state commercial shellfish license alone may not cover digging in a particular town.

Expected Results

Completing these steps is designed to let you operate legally as a seafood dealer, retailer, or processor in Maine. It does not guarantee buyers, prices, or sales volume. Many new dealers find that their first season is slower than they planned while they build relationships with harvesters and customers, so build that period into your budget. If you describe your seafood as fresh, local, or sustainably harvested, keep records that support those claims. Health and food claims in particular should be reviewed against FDA guidance before you publish them.
