How to Start an LLC in Mississippi

Forming a Mississippi LLC means filing one document with the Secretary of State, paying a $50 fee, and keeping up with a few ongoing requirements after that. The process is largely online, inexpensive compared to many states, and can be completed in a single sitting once you have your information ready. This guide walks through exactly what you need and each step in order, from choosing a name to filing your first annual report.

This article is informational only and is not legal or tax advice. Mississippi LLC law and tax rules can change, and your specific situation (multiple members, outside investors, licensed professions) may call for guidance beyond what's covered here. Consult a Mississippi business attorney or a CPA before you file if your situation is anything but straightforward.

What You'll Need Before You Start

Gather these items before you sit down to file. Having them ready means you can complete your Mississippi LLC formation online in one session instead of stopping partway through.

• A compliant LLC name that includes "Limited Liability Company," "L.L.C.," or "LLC" and is distinguishable from every other business name on file with the Secretary of State.
• A Mississippi registered agent with a physical street address in the state (no P.O. boxes).
• The names and addresses of the LLC's organizer(s) and, if you want them listed, the managers or members.
• A credit or debit card to pay the $50 filing fee through the online portal.
• An email address to create an account on the Secretary of State's filing system and receive confirmation of your filing.
• A written operating agreement (you'll draft this yourself or with an attorney; it isn't filed with the state, but you'll want it before you open a bank account).
• Your Social Security number or ITIN (or those of a responsible party) to apply for an EIN after formation.

Step-by-Step: How to Form an LLC in Mississippi

Step 1: Choose and Check Your LLC Name

Under Miss. Code Ann. § 79-29-109, your Mississippi LLC name must contain the words "limited liability company" or the abbreviation "L.L.C." or "LLC." It can include a member's or manager's name, but it must be distinguishable on the Secretary of State's records from every other domestic or foreign corporation, nonprofit, limited partnership, LLP, or LLC already registered or reserved in Mississippi.

Search the Mississippi Secretary of State business name search before you get attached to a name. If the exact name (or something confusingly close to it) is already taken, your filing will be rejected and you'll lose time refiling.

Tip: Search for close variations too, not just the exact name. "Distinguishable on the record" is a lower bar than most people assume, and minor differences like punctuation or "The" at the front usually aren't enough to clear it.

Step 2: Reserve Your Name (Optional)

If you're not ready to file your Certificate of Formation immediately but want to lock in a name, you can reserve it for $25. The reservation holds the name for 180 days, which gives you time to finish your registered agent arrangements, draft an operating agreement, or line up financing before you officially form the LLC.

This step isn't required. Most people who are ready to file skip straight to Step 4.

Step 3: Appoint a Mississippi Registered Agent

Every Mississippi LLC must continuously maintain a registered agent and registered office in the state under Miss. Code Ann. § 79-29-113. Your agent can be:

• An individual who resides in Mississippi, or
• A domestic or authorized foreign corporation, nonprofit corporation, or LLC whose business office matches the registered office address.

You have two options under the Mississippi Registered Agents Act:

• Commercial registered agent: Files a listing statement with the Secretary of State (a $100 fee) and appears on the state's public agent list. Commercial agents must accept or decline representation within 14 days of being named.
• Noncommercial registered agent: Doesn't register separately with the state, but you must have that person's or entity's permission before listing them, and they need to be reliably available at that address during business hours.

Many single-member LLC owners act as their own registered agent to save money, which is legal as long as you have a Mississippi street address and are actually present to receive documents. The tradeoff: your home address becomes part of the public record, and if you're out of town when a lawsuit is served, you can miss a deadline. A commercial registered agent service typically runs $100 to $300 per year and keeps your home address off public filings.

Step 4: File the Certificate of Formation

This is the actual formation document that creates your Mississippi LLC. File Form F0100, Certificate of Formation, through the Secretary of State's online filing portal. The filing fee is $50.

You'll need to provide:

• The LLC's name
• The name and address of your registered agent
• The principal office address
• Whether the LLC will be member-managed or manager-managed
• The name and address of at least one organizer

Most online filings are approved and filed immediately. If your filing needs staff review for any reason, it's normally returned filed within 24 hours. There is no published expedited-processing fee for LLC formation in Mississippi because the online system is already same-day or next-day; if you file by paper, expect a considerably longer wait, so online filing is the practical choice for anyone who wants to form their LLC quickly.

Common mistake: Listing a registered agent address that doesn't match a real, staffed physical location. If your agent can't be found at the address on file, you risk losing your liability protection through administrative dissolution down the road.

Step 5: Create an LLC Operating Agreement

Mississippi doesn't require you to file an operating agreement with the state, and it isn't legally mandatory to have one at all. That said, skipping it is one of the most common mistakes new LLC owners make. An operating agreement spells out ownership percentages, how profits and losses are divided, what happens if a member wants to leave or the LLC needs to dissolve, and who has authority to sign contracts or open accounts on the LLC's behalf.

Without one, Mississippi's default LLC statute governs your business, which may not match what you and your co-owners actually intended. Banks also frequently ask to see an operating agreement before opening a business account, especially for multi-member LLCs.

Step 6: Get an EIN from the IRS

An Employer Identification Number (EIN) is a federal tax ID for your LLC, and you'll need one to open a business bank account, hire employees, or elect corporate tax treatment. You can apply directly on the IRS website at no cost. The online application typically issues your EIN immediately once submitted.

Common mistake: Paying a third-party service to "obtain" your EIN. The IRS issues EINs for free, and any site charging a fee for this step is charging for something you can do yourself in about ten minutes.

Step 7: Open a Business Bank Account

Once you have your filed Certificate of Formation and your EIN, open a dedicated business checking account. Keeping business funds separate from personal funds is one of the practical requirements for maintaining the liability shield an LLC is supposed to provide; commingling funds is a common reason courts have pierced the corporate veil in disputes. Bring your Certificate of Formation, EIN confirmation letter, and operating agreement (most banks will ask for it) when you open the account.

Step 8: Register for Mississippi Taxes

Mississippi has no LLC-specific state tax and no fee for the annual report. By default, an LLC is a pass-through entity, meaning members report their share of income on their personal Mississippi returns, which for tax year 2026 are taxed at 0% on the first $10,000 of taxable income and 4% above that.

If you elect to have your LLC taxed as a corporation, it would instead owe Mississippi corporate income tax (0% on the first $5,000 of taxable income, 4% on the next $5,000, and 5% above $10,000), plus a franchise tax of $0.50 per $1,000 of capital in excess of $100,000 (minimum $25) for tax year 2026. That franchise tax is being phased out and is scheduled for full repeal effective January 1, 2028.

If your LLC sells taxable goods or services, register with the Mississippi Department of Revenue for a sales tax permit. There's no fee for the permit itself, though a bond may be required if you don't have a permanent Mississippi location. Mississippi's state sales tax rate is 7%. There's no single statewide general business license, but check with your city or county, since local privilege licenses and industry-specific occupational licenses are common depending on what you do.

Step 9: File Your Annual Report

Every Mississippi LLC must file an Annual Report (Form F0108) every year, and it must be filed online. It can be submitted any time on or after January 1, and it's due by April 15. There's no fee for the LLC annual report. Missing it can eventually lead to administrative dissolution of your LLC, so put the deadline on a calendar you actually check.

Mississippi LLC Formation Costs at a Glance

Item	Cost
Certificate of Formation (Form F0100)	$50
Name reservation (optional, 180 days)	$25
Commercial registered agent listing (if applicable)	$100 (state fee) plus the service's own annual charge, often $100 to $300
Annual Report (Form F0108)	$0
EIN from the IRS	$0

If a fee you need isn't listed here or in this guide, confirm the current amount directly on the Mississippi Secretary of State Business Services page before you rely on it.

How Long Does It Take?

Online Certificate of Formation filings are typically approved immediately, and filings that need manual review are usually returned within 24 hours. Paper filings take substantially longer and generally aren't worth the wait unless you have no other option. Once your Certificate of Formation is filed, expect your EIN the same day (online IRS application) and a business bank account open within a few business days, assuming you have all your documents ready.

Common Mistakes to Avoid

• Skipping the name search. A rejected filing costs you time, and if you've already ordered a sign, business cards, or a domain, it costs you money too.
• Using a P.O. box as your registered office. Mississippi requires a physical street address for your registered agent.
• Forgetting the annual report. It's free, but it's easy to forget precisely because there's no fee reminder tied to a payment. Set your own reminder for early April.
• Not separating business and personal finances. This undermines the liability protection that's the whole point of forming an LLC in the first place.
• Assuming Mississippi requires a general business license. It doesn't at the state level, but local privilege licenses and industry-specific permits often apply, so check with your city or county clerk.

What You Can Expect Once You're Formed

Once your Certificate of Formation is filed and approved, your Mississippi LLC generally exists as a legal entity separate from you personally, which is intended to shield your personal assets from most business debts and lawsuits tied to the company. That protection is not automatic or absolute: it typically depends on maintaining the formalities above, like keeping finances separate and filing your annual report on time. Many owners find they can complete formation, get an EIN, and open a bank account within the same week, though your timeline will depend on how quickly you gather your documents and how your bank schedules appointments.

Final Thoughts

Starting an LLC in Mississippi is one of the more straightforward state filings in the country: one form, a $50 fee, and a same-day or next-day turnaround if you file online. The steps that trip people up aren't the filing itself, they're the surrounding pieces: choosing a registered agent who'll actually be there to receive mail, writing an operating agreement instead of skipping it, and remembering the free annual report every April 15. Work through the checklist above in order, and you'll have a properly formed Mississippi LLC without unnecessary delays or fees.

If your business involves multiple owners, outside investment, a licensed profession, or anything beyond a straightforward single-member LLC, talk to a Mississippi attorney or CPA before you file.
