Any business formed outside Mississippi must obtain a Mississippi Certificate of Authority from the Secretary of State before transacting business in the state. Skip the step and the company faces civil penalties of up to $1,000 per year and loses the right to file lawsuits in Mississippi courts until it registers. The form, fee, and supporting documents depend on whether you are a corporation, LLC, or partnership, but the core requirement is the same across entity types.
Who Has to Register
Foreign corporations (those incorporated in another state or country) must obtain a Certificate of Authority before transacting business in Mississippi.1Justia. Mississippi Code 79-4-15.01 – Authority to Transact Business Required Foreign LLCs file a parallel application under a separate chapter of the Mississippi Code.2Justia. Mississippi Code 79-29-1003 – Registrations, Application to Transact Business Foreign limited partnerships and LLPs register under Mississippi’s Uniform Limited Partnership Act. Different forms, different fees, same principle.
A foreign corporation that acts as a general partner in a partnership transacting business in Mississippi is automatically treated as transacting business itself and must register.1Justia. Mississippi Code 79-4-15.01 – Authority to Transact Business Required
Some industries carry extra layers. Insurance companies must also register with the Commissioner of Insurance under Title 83.3FindLaw. Mississippi Code Title 83 – Insurance 83-5-1 Financial institutions, medical practices, and other regulated entities may face similar supplemental licensing.
What Counts as Transacting Business
The statute does not give an exhaustive definition, but it does list activities that do not require registration. A company can do any of the following in Mississippi without a Certificate of Authority:1Justia. Mississippi Code 79-4-15.01 – Authority to Transact Business Required
- Maintain bank accounts
- Hold board or shareholder meetings
- Sell products through independent contractors
- Carry on internal corporate affairs
The list is not exhaustive, so other passive or isolated activities may also fall below the line. On the other side, a physical office, in-state employees, owned property, or regular solicitation of Mississippi customers almost always counts as transacting business. The determination turns on the nature, frequency, and continuity of what you do inside the state.
How to Apply
Foreign Corporations
A foreign corporation files an application with the Secretary of State containing:4Justia. Mississippi Code 79-4-15.03 – Application for Certificate of Authority
- The corporation’s legal name, or an acceptable alternate if that name is unavailable in Mississippi
- State or country of incorporation
- Date of incorporation and period of duration
- Street address of the principal office
- Name and address of a registered agent with a physical Mississippi location
- Names and business addresses of current directors and officers
You also need a certificate of existence (sometimes called a certificate of good standing) from your formation state, authenticated by that state’s Secretary of State or equivalent official.4Justia. Mississippi Code 79-4-15.03 – Application for Certificate of Authority Costs for that document typically run $5 to $25.
If your corporate name is already taken in Mississippi or does not meet the state’s naming rules, you can either add a designator like “Inc.” or “Corp.” for use in Mississippi, or adopt a fictitious name by filing a certified board resolution with the Secretary of State.
Foreign LLCs
Foreign LLCs file their own application. It asks for most of the same information plus LLC-specific items, including the date the LLC first did (or intends to do) business in Mississippi and its dissolution date, if any.2Justia. Mississippi Code 79-29-1003 – Registrations, Application to Transact Business A certificate of existence from the formation state and a Mississippi registered agent are both required.
Filing Fees
Fees vary by entity type:5Mississippi Secretary of State. Business Document Filing Fees
- Foreign for-profit corporation: $500
- Foreign nonprofit corporation: $100
- Foreign LLC: $250
Add the cost of the home-state certificate of existence and, if you hire one, a commercial registered agent service. Agent services commonly charge $50 to $350 per year.
What Happens If You Skip It
Operating without a certificate carries both a financial penalty and a procedural one. The financial side is modest: a foreign corporation that transacts business without authority owes $10 per day of noncompliance, capped at $1,000 per year, collectible by the Attorney General. The company also remains liable for all fees and taxes it would have owed had it registered on time.6Justia. Mississippi Code 79-4-15.02 – Consequences of Transacting Business Without Authority
The procedural consequence hurts more. An unregistered foreign corporation cannot file a lawsuit or maintain a court proceeding in Mississippi until it obtains a Certificate of Authority.6Justia. Mississippi Code 79-4-15.02 – Consequences of Transacting Business Without Authority If a customer stops paying or a partner breaches a contract, you cannot sue to collect or enforce. Others can still sue you. The statute of limitations keeps running while you scramble to register, and delays can permanently kill claims you would otherwise win.
One important limit on the penalty: failure to register does not void your contracts. The statute explicitly provides that the omission does not impair the validity of any contract, deed, mortgage, or lien, and does not prevent the corporation from defending lawsuits.6Justia. Mississippi Code 79-4-15.02 – Consequences of Transacting Business Without Authority Your deals stay enforceable. You just cannot be the party who walks into court first.
Staying in Good Standing
Annual Reports
Once registered, for-profit corporations and LLCs must file an annual report with the Secretary of State. Filing opens January 1 and closes April 15. Nonprofit corporations have until May 15.7Mississippi Secretary of State. Annual Reports The report updates your principal office address, registered agent, and current officers or managers. Missing the deadline puts you on the path to revocation.
Registered Agent
You must keep a registered agent with a physical Mississippi address for the entire time you hold the certificate. If the agent resigns or moves, file an updated notice with the Secretary of State promptly. A lapse means you can miss service of lawsuits and compliance notices.
Name or Home-State Changes
If a foreign corporation changes its legal name or its state of incorporation, it must obtain an amended Certificate of Authority. The requirements for the amendment mirror those for the original.8Justia. Mississippi Code 79-4-15.04 – Amended Certificate of Authority
Revocation and Reinstatement
The Secretary of State can revoke a foreign corporation’s certificate on any of these grounds:9Justia. Mississippi Code 79-4-15.30 – Grounds for Revocation
- Failing to file the annual report within 60 days after it is due
- Failing to pay franchise taxes or penalties within 60 days of the due date
- Going 60 days or more without a Mississippi registered agent
- Failing to notify the Secretary of State within 60 days of a change or resignation of the registered agent
- Filing a document that an officer, director, or agent knew was materially false
- Being dissolved or merged out of existence in the home state
When the Secretary of State identifies a ground for revocation, the corporation gets written notice and 60 days to fix the problem or show it does not exist.10Justia. Mississippi Code 79-4-15.31 – Procedure for and Effect of Revocation Ignore the window and the Secretary signs a certificate of revocation.
A revoked corporation can apply for reinstatement at any time. The application must confirm the grounds for revocation have been eliminated, show the corporate name still meets Mississippi requirements, and include a certificate from the Mississippi Department of Revenue confirming all required tax reports have been filed and all taxes and penalties paid.11Justia. Mississippi Code 79-4-15.32 – Appeal From Revocation Reinstatement relates back to the date of revocation, closing the gap in your authority, but the longer you wait the larger the tax bill grows.
Leaving Mississippi
A foreign corporation that no longer wants to operate in Mississippi should apply for a certificate of withdrawal through the Secretary of State. Filing for withdrawal formally ends the obligation to file annual reports, keep a registered agent, and pay franchise taxes going forward. Just closing up shop without withdrawing leaves you on the books, accumulating compliance obligations that eventually trigger revocation and penalties.
A Separate Registration You May Still Need
A Certificate of Authority is not the same as a tax registration. Since July 1, 2018, any out-of-state business with more than $250,000 in sales into Mississippi during any twelve-month period must register with the Mississippi Department of Revenue to collect and remit sales or seller’s use tax. The threshold applies even without a physical presence in the state. Companies with Mississippi property, employees, or agents servicing customers have physical nexus and must register regardless of sales volume.12Mississippi Department of Revenue. Business Tax Frequently Asked Questions You may need the Secretary of State filing, the Department of Revenue registration, both, or neither depending on what you actually do in the state.
