What is an EIN?

An EIN, or Employer Identification Number, is a unique nine-digit number assigned by the IRS to business entities operating in the United States. It's essentially a Social Security number for your business, used to identify it for tax purposes. Even if you don't plan to hire employees immediately, an EIN is often required for opening a business bank account, obtaining licenses, and filing taxes as a marketplace business.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your marketplace business structure requires an EIN. Most LLCs, corporations, and partnerships in Maine need one, especially if they have employees or operate as a payment facilitator.
  2. Choose Your Business Structure: Decide on your legal structure (LLC, corporation, etc.). This choice impacts your tax obligations and liability. In Maine, LLCs are popular for their flexibility and pass-through taxation.
  3. Prepare Form SS-4: Download and complete IRS Form SS-4, the Application for Employer Identification Number. You'll need to provide information about your business, including its name, address, responsible party, and 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 and most efficient method.
  5. Receive Your EIN: If you apply online, you'll typically receive your EIN immediately. If you apply by fax or mail, it can take several weeks.
  6. Record Your EIN: Keep your EIN in a safe and accessible place. You'll need it for banking, taxes, and other official business purposes.
