This guide simplifies the process of obtaining an EIN for your co-founder business in Maine in 2026, ensuring a smooth and compliant launch. Let Lovie streamline the formation process for you and your co-founder.

What is an EIN?

An EIN is essentially a social security number for your business. It's a unique tax identification number assigned by the IRS to identify your business entity. You'll need it for various activities, including opening a business bank account, hiring employees, and filing taxes.

How to Apply for an EIN

  1. Determine Your Business Structure: Decide on your business structure (LLC, partnership, etc.). This decision impacts your EIN application. For co-founders, an LLC is common for its flexibility, but a C-Corp might be preferable if seeking venture capital.
  2. Check EIN Eligibility: Ensure your business requires an EIN. Most co-founder businesses in Maine will, especially if hiring employees or operating as a corporation or partnership. Sole proprietorships without employees may not need one.
  3. Gather Required Information: Collect all necessary information before starting the application, including your business name, address, the names and Social Security numbers of all co-founders, and the reason for applying.
  4. Complete the Online Application (Form SS-4): Access the IRS website and complete Form SS-4, the Application for Employer Identification Number. The online application is the fastest and most efficient method.
  5. Submit Your Application: After completing the online form, submit it electronically. You'll typically receive your EIN immediately upon successful submission.
  6. Receive and Verify Your EIN: Upon successful submission, you will receive your EIN. Verify that all information on the confirmation is accurate.
