What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit tax identification number assigned by the IRS to business entities. It's essentially a Social Security number for your business. You'll need an EIN to hire employees, open business bank accounts, file taxes, and more. For serial entrepreneurs managing multiple ventures, each distinct legal entity typically requires its own EIN.

How to Apply for an EIN

  1. Determine Eligibility: Ensure your Louisiana business entity is eligible for an EIN. Generally, any entity that is not a sole proprietorship without employees needs an EIN. This includes LLCs, corporations, and partnerships operating in Louisiana.
  2. Choose Your Entity Type: Select the appropriate business structure for your Louisiana venture (e.g., LLC, C-Corp). The entity type will influence the EIN application process and your tax obligations. Louisiana has specific regulations for each entity type.
  3. Gather Required Information: Collect all necessary information, including the legal name of your business, its address, the responsible party's name and SSN/ITIN, and the reason for applying for the EIN. Ensure all details are accurate to avoid delays.
  4. Complete the IRS Form SS-4: Fill out IRS Form SS-4, Application for Employer Identification Number. You can download the form from the IRS website or complete the application online. The online application is generally faster and more efficient.
  5. Submit Your Application: Submit the completed Form SS-4 to the IRS. You can apply online, by fax, or by mail. Online applications are typically processed immediately, while faxed or mailed applications may take several weeks.
  6. Receive and Store Your EIN: Once your application is approved, you'll receive your EIN from the IRS. Keep this number in a safe and accessible place, as you'll need it for various business activities, including opening bank accounts and filing taxes.
