What is an EIN?

An EIN, or Employer Identification Number, is essentially a Social Security number for your business. Issued by the IRS, it's a unique nine-digit tax identification number used to identify your business entity. Even as a solo founder, you might need one for various reasons, from opening a business bank account to hiring employees down the line.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your Maine business entity requires an EIN. Sole proprietorships without employees typically don't need one, but LLCs, corporations, and partnerships do. If you're a solo founder forming an LLC in Maine, you'll likely need an EIN.
  2. Choose Your Business Structure: Decide on your business structure (LLC, S-Corp, etc.). This impacts how you apply for the EIN. In Maine, forming an LLC is a popular choice for solo founders due to its liability protection.
  3. Prepare Form SS-4: Download and complete Form SS-4, the Application for Employer Identification Number. This form requires information about your business, such as its name, address, and the reason for applying.
  4. Submit Your Application: You can apply for an EIN online through the IRS website, by fax, or by mail. The online application is the fastest method and is generally recommended.
  5. Receive Your EIN: If you apply online, you'll receive your EIN immediately. If you apply by fax or mail, it can take several weeks.
  6. Verify Your EIN: After receiving your EIN, verify its accuracy on the IRS website. This ensures that all information is correct and prevents potential issues in the future.
