Look up a Mississippi company
Mississippi only allows its search on its own site, so this opens in a new tab. It finds the company, not usually its EIN.
What the Mississippi business search shows
The Mississippi Secretary of State keeps Mississippi’s record of companies formed or registered there. Use it to confirm a company’s exact legal name and whether it is active.
The Mississippi business ID
The Mississippi Secretary of State gives every company a business ID when it is formed. It identifies the company in state records, and it is not the company’s EIN.
Check if a Mississippi LLC is active
Search the company in the Mississippi business search and open its record. The status tells you whether the state counts the company as active. Words such as dissolved, revoked, forfeited, inactive or delinquent mean it is not in good standing, usually because an annual filing or fee was missed, and the company may need to be reinstated before it can do business there.
To prove a company is in good standing to a bank, a lender or another state, order a Certificate of Good Standing from the Mississippi Secretary of State. Our LLC status check reads the status from public data where a state publishes it.
Good to know in Mississippi
- Mississippi's LLC annual report must be filed online; there is no paper version. Along with the registered agent, principal office and managers or a member, it asks whether the company has a written operating agreement and for a brief description of its business, and an LLC that does not file can be administratively dissolved.
- Mississippi taxes an LLC the way the IRS classifies it. An LLC treated as a partnership files an informational return and skips the franchise tax lines, while one treated as a corporation, including an LLC that elects S corporation status, files as a corporation and owes Mississippi franchise tax, which is being phased down and is repealed effective January 1, 2028.
- Mississippi charges a contractor's tax on the prime contractor for nonresidential construction contracts above a set size, in place of sales tax on the component materials. Before work begins the prime contractor applies for a Material Purchase Certificate for the job on TAP, and subcontractors buy materials under that certificate; residential work stays under ordinary sales tax.
