As an international founder, securing an Employer Identification Number (EIN) is a crucial step in establishing your business presence in Illinois. This guide provides a clear roadmap for obtaining an EIN, even without a Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN).

What is an EIN?

An Employer Identification Number (EIN) 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 your company for tax purposes and to open business bank accounts. Even if you don't plan to hire employees immediately, an EIN is often required for various business activities.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your Illinois business entity is eligible for an EIN. Most LLCs and corporations are eligible, even if owned by non-US residents.
  2. Complete Form SS-4: Download and complete IRS Form SS-4, Application for Employer Identification Number. This form requires information about your business, including its name, address, and type of entity.
  3. Provide a US Address (If Possible): While not strictly required, providing a US address on Form SS-4 can expedite the EIN application process, especially if you plan to open a bank account in the US.
  4. Submit Form SS-4: You can submit Form SS-4 online, by fax, or by mail. Online submission is generally the fastest method.
  5. Await EIN Confirmation: After submitting Form SS-4, the IRS will process your application and issue your EIN. The processing time can vary depending on the submission method.
  6. Receive Your EIN and Keep it Safe: Once your EIN is issued, you'll receive a confirmation notice from the IRS (Form CP 575). Keep this document in a safe place, as you'll need it for various business-related activities.
