What the Certificate does

The Certificate of Formation creates the Mississippi LLC record. It does not automatically create:

Operating agreement

Sales tax permit/account
Employer withholding account
Unemployment employer account
Local license
Professional or industry license
Annual report filing

Information to prepare

Before filing, prepare:

LLC legal name
Registered agent information
Principal office or mailing information requested by the portal
Organizer information
Payment method
Whether you need any follow-up tax or license registrations

After approval

Save the approved Certificate of Formation.
Sign the operating agreement.
Get EIN from IRS if needed.
Register DOR tax accounts through TAP if required.
Register unemployment employer account if hiring.
Check local and industry licenses.
File the free domestic LLC annual report by April 15.

Practical note

The approved Articles or Certificate creates the LLC record, but it does not finish the business setup. After approval, use the same legal name and address consistently on the EIN application, bank account, state tax accounts, licenses, and operating agreement. If the state record has a typo or old address, fix it before building more registrations on top of it.
