How This EIN Guide Works

The IRS online EIN application provides instant approval for applicants with a valid Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN). The system is available Monday through Friday, 7 a.m. to 10 p.m. Eastern Time.

The application process takes approximately 15-20 minutes if you have all required information ready. You will receive your EIN immediately upon successful completion, and can download your confirmation letter.

The online system guides you through questions about your LLC structure, business activities, and responsible party information. Answers determine your tax classification and filing requirements.

  • The online session expires after 15 minutes of inactivity
  • Print or save your confirmation letter immediately upon completion
