MS SOS Business Search 2026: Entity Lookup & Filings

What Do You Need From Mississippi Business Services?

Choose your task first. The public search, filing login, annual-report workflow, document-order system and Business Reports tool solve different problems.

Complete the MS SOS Business Search Step by Step

The public portal does not require a filing account. Start with the information you know, broaden the wording when necessary, and verify the complete profile rather than relying on one result row.

The public portal is the final action after choosing the correct search route above.

Choose Starting With, All Words, Any Words, Sounds Like or Exact Match

The matching option changes the result set more than adding extra words. Use this order to avoid zero results or hundreds of irrelevant matches.

What the Mississippi Registry Includes—and What It Does Not

A missing result does not automatically mean a business is fraudulent. Some structures do not create a separate Secretary of State entity record, and several important checks belong to other agencies.

Business ID is not an EIN

The Mississippi Business ID is the state registry number used to find the entity and begin filings. An EIN is a separate nine-digit federal identifier issued by the IRS. Do not place an EIN into the Business ID field or expect the public entity profile to display it.

Current BOI rule and solicitation warning

A 2026 Mississippi SOS notice explains that FinCEN’s March 26, 2025 interim final rule removed federal beneficial-ownership-information reporting for entities created in the United States and for U.S. persons. An entity created outside the United States and registered here should check FinCEN directly for its current duties.

Use the state notice to understand the warning, then use FinCEN only for the live federal rule or a foreign-created entity’s deadline.

Build a Mississippi Business Record Folder Before Filing

The official Business Welcome Packet separates public SOS records from the company’s private governance, tax and financial records. Keeping those categories separate prevents Business ID, EIN, ownership and login confusion.

Use the legal name consistently

Use the exact legal name and Business ID on annual reports, amendments, reinstatement requests and support questions. When a brand or DBA appears on invoices, retain documentation connecting that name to the legal entity.

Do not store passwords in a shared compliance worksheet

The older welcome-packet worksheet includes a place for login information. A safer 2026 practice is to record the account email in the business folder while storing the password and recovery information in a reputable password manager with access limited to authorised users.

After setting up the folder above, the official packet can be used as a broader startup and maintenance checklist.

Read a Mississippi Entity Profile in the Right Order

Use the record to identify the legal entity first. Then use filing documents and separate licence or tax systems for questions the profile cannot answer.

Verify a Mississippi Company Before You Pay or Sign

The registry helps confirm legal identity. It should be combined with the contract, payment instructions, licensing records and any transaction-specific documents.

No Result? Follow This Search-Recovery Order

A zero-result screen often means the wording or search mode is too narrow. Use the following order before concluding that no Mississippi record exists.

Use Mississippi Business Reports for Lists, Filters and Excel Export

The ordinary entity search is best for one company. Mississippi Business Reports is the stronger tool when you need a filtered list, market research or a spreadsheet.

Use the official reports tool after deciding which filters answer your research question.

Public Search or Mississippi Business Filing Login?

Searching a public record and changing a business record are separate tasks. Do not create an account merely to look up a company.

Create a filing account

1. Open the Business Filings login page.
2. Select Register when you do not already have an account.
3. Enter your name, business address and business email.
4. Your email becomes the username.
5. Use the temporary password sent by email.
6. Create your own password and sign in.

Payment and submission workflow

The official FAQ lists American Express, Visa, MasterCard, Discover, e-check and an approved ACH account as payment options. Some forms can be completed through the online system, printed and mailed with a check, but paper processing takes longer and old blank forms should not be used.

After submission, the system checks many fields and returns acceptance, filing documents or correction instructions by email. Some eligible filings are approved immediately; others require staff review. Keep the confirmation email and invoice.

Check or File an MS SOS Annual Report

Profit corporations, nonprofit corporations and LLCs operating in Mississippi file annual reports online. The deadline and fee depend on the entity type and whether it is domestic or foreign.

Nonprofit annual report vs. charity registration

The nonprofit corporation annual report maintains the entity’s Business Services record. It is not the same as the separate charitable-organization registration or renewal that may apply when an organisation solicits contributions. A nonprofit can therefore have two different annual compliance tasks with different portals and information.

Prepare this information before filing

• Business ID copied from the public entity profile
• Current legal name and entity type
• Business email monitored by an authorised person
• Principal street and mailing addresses
• Registered-agent name and Mississippi physical address
• Officers, directors, managers or members requested by the form
• Six-digit NAICS code closest to the primary business activity
• Corporation stock information when the report requests it
• Payment method for a fee-bearing report

Complete the report without opening the wrong entity

1. Search the entity and copy its Business ID.
2. Confirm entity type, status and state of incorporation.
3. Log in to Business Filings with the authorised account.
4. Select the correct annual-report year and entity.
5. Review every pre-populated field rather than clicking through automatically.
6. Correct permitted address, agent and official information.
7. Choose the closest six-digit NAICS activity when an update is required.
8. Confirm the fee shown for that entity type.
9. Submit and save the confirmation email, invoice and filed document.
10. Recheck the public profile after processing.

Common blockers and what to do

What happens after submission

Some online documents are approved and returned immediately. Others require staff review. The official FAQ says reviewed documents should generally be returned by email within about 24 hours, but that is guidance rather than a guaranteed deadline. A rejection email should explain the issue preventing filing.

Recognise a 2026 annual-report mailer scam

The official one-page alert says private entities are sending mailers that offer to prepare 2026 annual reports for a fee and may resemble government correspondence. Domestic LLC owners can file directly at no cost, and the deadline is April 15.

• Read the fine print for a private-company disclaimer.
• Compare the requested amount with the official entity-specific fee above.
• Confirm the payment domain before entering card or bank details.
• Report deceptive solicitations to the SOS or the Attorney General.
• Attorney General Consumer Protection Hotline: 1-800-281-4418.

Use the official pages below only after confirming the deadline, entity type and fee above.

Good Standing, Administrative Dissolution and Reinstatement

A status label tells you the entity’s condition in the SOS registry. It does not replace a licence, tax-clearance, insurance or ownership check.

Reinstatement preparation

1. Search the entity and confirm the Business ID.
2. Open the dissolution or status-related filing.
3. Identify every missing annual report and fee.
4. Obtain a Mississippi Department of Revenue tax-clearance letter when the portal requires one for the corporation or LLC.
5. Save the clearance letter electronically.
6. Log in and select Reinstatement.
7. Enter the dissolved entity’s Business ID.
8. Upload required documents and fix validation errors.
9. Pay the reinstatement and overdue-report fees.
10. Confirm that the public status changes after acceptance.

Reinstatement blockers that cause repeat rejection

• Uploading a tax letter that is not the clearance document requested by the filing system
• Using the EIN instead of the Mississippi Business ID
• Leaving one delinquent annual-report year unresolved
• Paying only the reinstatement application fee and omitting required report fees
• Using an expired or unavailable name for a foreign entity
• Submitting through an account whose email cannot receive acceptance or rejection notices

Order and Verify a Certificate of Good Standing

Ask the receiving bank, lender, agency or transaction partner what it requires. A public profile, certified filing and Certificate of Good Standing/Existence serve different purposes.

Order the correct document

1. Search the entity and confirm the Business ID.
2. Ask the requester exactly which document is acceptable.
3. Log in to Business Filings.
4. Select Order Documents.
5. Choose the entity and document type.
6. Review the live fee before payment.
7. Download or retain the certificate and receipt.
8. Use certificate verification when a third party sends you an electronic certificate.

Most certificates and filing copies are available after online payment. Call Business Services when the required document is not listed.

Registered Agent, Officer, Director or Owner?

These public roles are not interchangeable. Identify the role before drawing a conclusion about ownership, management or authority.

Mississippi agent rules that matter

• A noncommercial agent can be an individual, corporation or LLC with a physical Mississippi address.
• The company should obtain the noncommercial agent’s permission before listing the agent.
• Noncommercial agents are not automatically notified when selected.
• Commercial and noncommercial agents perform the same core service-of-process role when properly appointed.
• Registered-agent changes are handled through the amendment workflow.
• An agent-address change can affect every company profile using that agent.

Check a Mississippi Business Name or Fictitious Business Name

A public name search is a screening step. Final acceptance depends on the filing, and registration does not create complete trademark clearance.

Name reservation

The standard Mississippi entity-name reservation is currently listed at $25 and holds an available name for a 180-day period. Official materials describe the standard period as nonrenewable. A reservation holds a name temporarily; it does not form the entity.

Fictitious business name

Mississippi’s central fictitious-business-name system covers trade names, assumed names, aliases and DBAs. Registration, amendment, assignment and withdrawal are currently listed at $25 each.

Prepare a fictitious-name filing

• Identify the individual or legal entity with authority to use the name.
• Use the owner’s exact legal name and Business ID when an entity owns the DBA.
• Prepare the owner’s mailing address.
• List the street address of each Mississippi location requested by the form.
• Describe the nature of the business clearly.
• Use an email address monitored for filing notices.
• Search similar entity, fictitious and trademark names before payment.

What to Do When a Business Filing Uses Your Name or Address

Effective July 1, 2026, Mississippi’s Business Filing Fraud Prevention Act provides an administrative process for a person affected by a wrongful business filing.

Use the declaration—not an ordinary amendment

The official two-page form is designed for allegations that a business was created with your information, your name was listed without permission, your address was used, or an existing record was changed without permission. Filing an amendment to an entity you do not control can create additional confusion or imply authority you do not have.

Information the form asks you to provide

Prepare a useful evidence packet

1. Search the entity and record its Business ID.
2. Save the current profile as a PDF or dated screenshot.
3. Download the formation, amendment or annual-report document containing the disputed information.
4. Highlight the name, address or change you did not authorise.
5. Write a chronological explanation with filing dates and how you discovered the record.
6. Attach identity or address evidence only when genuinely relevant, and redact unrelated sensitive numbers.
7. Complete every applicable field on the declaration.
8. Sign it under penalty of perjury before a notary.
9. Keep the full signed packet and proof of submission.

Submit the completed declaration

The Secretary of State’s July 2026 instructions allow a completed notarised form to be sent by email to customerservice@sos.ms.gov or mailed to P.O. Box 136, Jackson, MS 39205-0136. Business Services reviews the complaint; submitting the form does not promise an immediate dissolution or determine separate civil or criminal claims.

Read the process page first, then download the official Rev. 5/26 declaration when this is the correct complaint route.

Use the Correct Mississippi Business Tool

The entity search does not answer every business question. Use the service designed for the record or action you need.
