What is an EIN?

An EIN, or Employer Identification Number, is a unique nine-digit number assigned by the IRS to business entities. It's essentially a Social Security number for your business, used to identify it for tax purposes. Even if you're a solo consultant, you might need an EIN.

How to Apply for an EIN

  1. Determine Eligibility: Ensure your Illinois consulting business meets the IRS requirements for obtaining an EIN. Generally, any entity that hires employees or operates as a corporation or partnership needs one.
  2. Choose Your Business Structure: Decide on your business structure (LLC, S-Corp, etc.). This impacts your EIN application. For Illinois consultants, LLCs and S-Corps are common choices.
  3. Gather Required Information: Collect all necessary information, including your business name, address, responsible party details (Social Security number or ITIN), and the reason for applying.
  4. Complete the Online Application (Form SS-4): Access the IRS website and complete the online EIN application (Form SS-4). The online application is the fastest and most efficient method.
  5. Submit the Application: Carefully review your application before submitting it electronically to the IRS.
