Home-Based & Micro Businesses in Mississippi - FAQ 7

How do I get a tax number for my business?

Contact the IRS to obtain a federal employer identification number or EIN (telephone 800/829-3676 and request FORM SS-4). Most all businesses with one employee or more should have an EIN.

Contact the Mississippi State Tax Commission to obtain a Mississippi Business Registration Application (telephone 601/923-7000 and request FORM 70-001-00-1). All businesses in Mississippi should complete this process.
