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 it for tax purposes. Even if you're an international founder without a Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN), you can still obtain an EIN for your Colorado business.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your Colorado business entity is eligible for an EIN. Most LLCs and corporations are eligible. As an international founder, you are eligible even without an SSN/ITIN.
  2. Complete Form SS-4: Download and complete IRS Form SS-4, Application for Employer Identification Number. You can find the form on the IRS website. Fill it out accurately, providing all required information about your Colorado business.
  3. Provide a Responsible Party: Designate a 'responsible party' on Form SS-4. This individual controls, manages, or directs the entity and the disposition of its funds and assets. This person does not need to be a US resident but will need to provide foreign address information.
  4. Submit Your Application: You can submit Form SS-4 via mail, fax, or online (if available). As an international founder without an SSN/ITIN, online submission might not be possible. Fax is often the fastest method.
  5. Wait for Processing: The IRS processing time varies. Faxed applications typically take 4-5 business days. Mailed applications can take several weeks. In 2026, expect potential delays due to increased application volume.
  6. Receive Your EIN: Once your application is approved, you'll receive your EIN from the IRS via mail or fax (depending on your submission method). Store this number securely, as you'll need it for various business activities.
