- Has more than one member

EIN vs Mississippi tax registration
The EIN is federal. Mississippi DOR registration is state-level. If the LLC sells taxable goods, has withholding obligations, or needs other Mississippi business tax accounts, register separately through the state tax system.
Practical note
Use the EIN consistently after it is issued. The LLC legal name on the IRS confirmation letter should match the state formation record, bank application, payroll account, tax portal, and vendor forms. If you apply too early or use a name that differs from the approved state record, account setup can become slower even if the EIN itself is valid.
