How to Start a Gulf Charter Boat Business in Mississippi: MDMR Charter License and Coast Guard Rules

If you plan to take paying passengers out of Biloxi, Gulfport, Ocean Springs or Bay St. Louis, the paperwork has more layers than most first-time operators expect. Mississippi has no single statewide business license. Instead, you assemble several separate registrations and licenses: an entity filing with the Secretary of State, a city privilege license, a state saltwater license for the captain from the Department of Marine Resources (MDMR), a federal Coast Guard captain's license, and, if your charter fees are taxable, a sales tax registration with the Department of Revenue. This guide covers each one in the order most charter operators handle them, so you can build a checklist for your own charter boat Mississippi business.

This article is informational content, not legal or tax advice. Fees and rules change. Confirm every figure with the agency named before you spend money or sign anything. For questions about liability, insurance, tax treatment or hiring, talk with a Mississippi attorney and a certified public accountant (CPA).

What You Need Before You Start

Gather these items before you visit any office or submit any form:

• A proposed business name, checked against the Secretary of State business search
• A Mississippi physical street address for your registered office and registered agent
• A $50 filing fee for an LLC Certificate of Formation (or the Articles of Incorporation fee if you form a corporation)
• Your vessel's registration and proof of insurance, which MDMR will ask about
• Documents proving your Mississippi residency, if you want the resident license rate (ask the Biloxi office exactly what to bring)
• A list of every captain and crew member who will work the boat, along with their credentials
• A federal Coast Guard captain's license for each person who will serve as captain
• A budget that covers each license fee, the $25 corporate annual report if you incorporate (the LLC annual report has no fee), and insurance quotes

Step-by-Step: Starting Your Mississippi Charter Business

Step 1: Form your business entity

Most small charter operators form a Mississippi limited liability company (LLC). The Certificate of Formation (Form F0100) costs $50 and is filed online through the Secretary of State's Business Services online filing portal at corp.sos.ms.gov. Most documents paid for online are approved and filed immediately. Filings that need staff review are normally returned filed within 24 hours. Paper filings take significantly longer, so file online unless you have a specific reason not to.

Your name must include the words limited liability company, the abbreviation L.L.C., or LLC. It must also be distinguishable on the Secretary of State's records from any existing Mississippi entity or reserved name. If you need time to decide, you can reserve a name for 180 days for a $25 fee. The reservation rules are in the Secretary of State's guidance at https://www.sos.ms.gov/content/documents/pol_res/llcs/1revisedLLCact.pdf.

Every Mississippi LLC must keep a registered office and a registered agent in the state. The agent must be an individual Mississippi resident or an entity authorized to do business in Mississippi, and the agent's office must match the registered office. A post office box is not enough. If you use a commercial registered agent, that agent files a listing statement with the Secretary of State for $100 and must accept or decline your appointment within 14 days. A noncommercial agent needs your permission before you list them, but does not register with the state.

An LLC must also file an annual report. The MS LLC Annual Report (Form F0108) is due April 15 each year, may be filed on or after January 1, must be filed online, and carries no state fee. Missing it can lead to administrative dissolution, which is an expensive problem to fix in the middle of a busy season.

If you form a corporation instead, the Articles of Incorporation (Form F0001) carry the same $50 filing fee, and the corporate annual report (Form F0008) costs $25 and is due April 15 for profit corporations. Most charter owners choose an LLC because it is simpler to run, but ask your CPA which structure fits your tax situation.

Step 2: Register a fictitious name if you will operate under a different name

If your boat will trade as something other than your LLC's legal name, such as a fishing or sightseeing brand, you need a Fictitious Business Name Registration (Form F0070). The fee is $25. Filed with the Secretary of State's Business Services Division, not the county. Check the current fee schedule at https://www.sos.ms.gov/content/documents/Business/FeeSchedule.pdf before you file.

Step 3: Get your city privilege license

Mississippi does not issue a general state business license. Under Miss. Code 27-17, every city, town and village issues its own privilege license to businesses that operate within its limits. Counties license only businesses located outside municipal limits. In practice, this means your charter's home base decides which local office you deal with.

Gulf Coast charter operations commonly work out of harbors and marinas in Biloxi, Gulfport, Ocean Springs and Bay St. Louis. If your office, slip, or launch sits inside one of those cities, the city is the agency to call. If your business operates from an unincorporated area, the county is the right office. Ask the city clerk or revenue office for the current privilege license fee, the application form, and how they classify a charter fishing or tour operation. Do not assume that a license from one coastal city covers activity in another.

Step 4: Obtain your MDMR Charter Guide license

The captain who takes paying passengers out on the water needs the state charter license from MDMR. MDMR sells resident commercial saltwater licenses in person at its Biloxi license office at 1141 Bayview Ave, Biloxi, MS. The office phone is 228-374-5000. Call ahead to confirm hours and the document list, because MDMR sets the paperwork requirements for each license type.

The 2026 MDMR fee table lists these charter-related items:

• Charter Guide license: $200 for a Mississippi resident
• Charter Interstate Commerce: $20
• Additional Charter Captain: $10
• For-Hire Two-Day Bag Limit Endorsement: $100

Ask the Biloxi office which endorsements your trips actually require, because the name of an endorsement does not always tell you whether your specific trips need it. Ask the same question about the non-resident fee, since the table above shows the resident rate. Also ask whether an additional captain needs the $10 endorsement, or a full license of their own, before they take a paying trip.

Charter licenses expire one year from the date of purchase. Other commercial licenses expire April 30. Put the charter expiration date on your calendar the day you buy the license, and set a reminder two to three weeks ahead. Letting a charter license lapse while you have bookings is one of the most avoidable problems in this business.

Step 5: Get your Coast Guard captain's license

The state charter license does not replace federal credentials. For a boat that carries paying passengers, the captain generally needs a U.S. Coast Guard credential, commonly called an OUPV (Operator of Uninspected Passenger Vessels) license. It is issued by the federal government, separate from anything MDMR sends you, and it has its own application, eligibility, and renewal requirements. Check the current requirements directly with the Coast Guard before you schedule any training or testing, since federal credentialing rules can change.

Step 6: Register for sales tax if your charter fees are taxable

Businesses that make retail sales register with the Mississippi Department of Revenue (DOR) for a sales tax permit. The DOR describes the permit as the privilege of operating a business in Mississippi. There is no fee for the permit, although the DOR may require a bond from an applicant with no permanent Mississippi location.

Whether your charter fares, fishing packages, or add-on services are taxable sales is a question for the DOR. Ask before you open for business. Mississippi's state sales tax rate is 7%, with no county add-on. City levies apply only in Jackson and Tupelo, so a Biloxi, Gulfport, Ocean Springs or Bay St. Louis charter does not pick up a city add-on from these rules. Confirm that with the DOR as well, since local rules can change. Start the application at https://www.dor.ms.gov/business/sales-use-tax/registration-information-sales-and-use-tax-applicants.

Step 7: Set up your tax treatment with a CPA

An LLC that is treated as a pass-through entity reports its income on the members' Mississippi returns. It does not pay a separate LLC annual state tax, and the franchise tax does not apply to an LLC taxed as a partnership. If your LLC is taxed as a corporation, it pays Mississippi corporate income tax and the franchise tax. The franchise tax is set at $0.50 per $1,000 of capital above $100,000 for tax year 2026, with a $25 minimum, and it is repealed effective January 1, 2028. Because the choice of tax treatment affects your entire budget, sit down with a CPA before you pick an election.

Step 8: Line up insurance, vessel documents and crew

Insurance is the step most likely to delay an opening. Get written quotes from marine insurers and ask each one what it needs to see from MDMR and the Coast Guard, so you do not buy coverage that does not match your license. Ask MDMR the same question when you visit the Biloxi office. This guide does not list premium figures, because they vary widely with the vessel, the passenger count, and your history.

For crew, Mississippi has no state minimum wage law, so federal wage rules set the baseline for deckhands. Treat every person who works the boat as a potential employee until a CPA or attorney tells you otherwise, and make sure each captain on the boat holds the right credential.

Step 9: Build a compliance calendar before your first trip

Write down every date that can shut you down. For most charter operators, that list includes the LLC annual report due April 15, the charter license expiration one year from purchase, the April 30 expiration for other commercial licenses, and any city privilege license renewal the city sets. Keep copies of every license and filing receipt in one folder, and check the status of your LLC in the Secretary of State business search each year.

Expected Results

A well-organized launch can help you open on schedule. Online formation with the Secretary of State is typically the fastest step, while the local privilege license, MDMR license, and Coast Guard credential each depend on the agency's own workload and on whether your paperwork is complete. Expect the process to take longer if your insurance, vessel registration, or captain credentials are still in progress.

Once your entity, licenses, and insurance are in place, you can usually focus on operations, bookings, and customer experience. Results such as bookings, repeat customers, and revenue depend on your location, pricing, reputation, and the season, so no timeline or outcome is guaranteed.

Tips for a Smoother Launch

• Call the MDMR Biloxi office and the city clerk for your home port before you buy anything. Ask both for the current document list in writing or by email.
• Reserve your LLC name early if you have a brand you want to protect, then file the Certificate of Formation when you are ready to launch.
• Choose a registered agent with a reliable Mississippi street address and a process for forwarding documents quickly, since missed service of process can be serious.
• Check whether your harbor or marina requires its own permits, insurance certificates, or slip agreements before you sign a dock contract.
• Ask your insurer which licenses and certificates it needs to see, then carry copies on the boat.
• Keep a single compliance calendar with every expiration date and reminder set at least two weeks early.

Common Mistakes to Avoid

• Looking for a state business license. Mississippi does not issue one. The Secretary of State filing is a registration, and your real local permission comes from your city or county.
• Filing a fictitious name with the county. It goes to the Secretary of State, at $25.
• Treating the Coast Guard credential as a substitute for the state license. You need both, and they come from different agencies.
• Letting the charter license expire mid-season. Charter licenses run one year from purchase, while other commercial licenses expire April 30. Track them separately.
• Missing the April 15 LLC annual report. The fee is $0, but a missed filing can lead to administrative dissolution.
• Using a registered agent without a Mississippi street address. A post office box does not meet the requirement.
• Assuming one coastal city's privilege license covers the whole coast. Each city and county handles its own licensing.
• Booking trips before every license and insurance policy is in hand. A single unlicensed trip can create liability and cost you the customer relationship.
• Relying on Mississippi wage rules alone. Mississippi has no state minimum wage law, but federal rules still apply to your crew.

When to Get Professional Help

A single-owner charter with one boat and one captain can often be set up with the steps above. Bring in a professional before you proceed if you plan to hire crew, operate more than one vessel, carry passengers under a multi-owner structure, need custom insurance terms, or are unsure how your charter fees are taxed. An attorney can review your entity choice, contracts, and liability waivers, and a CPA can set up your tax treatment and payroll.
