What is an EIN?

An EIN, or Employer Identification Number, is a unique tax ID assigned by the IRS to identify your business. It's like a Social Security number for your company. You'll need an EIN to hire employees, open a business bank account, and file certain taxes.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your Illinois productized service business meets the IRS requirements for obtaining an EIN. Generally, any business entity other than a sole proprietorship without employees will need an EIN.
  2. Choose Your Business Structure: Decide on the legal structure of your Illinois productized service business (e.g., LLC, S-corp). This will influence how you apply for the EIN and your tax obligations.
  3. Gather Required Information: Collect all necessary information, including your business name, address, the responsible party's (owner, partner, officer) name and SSN/ITIN, and the reason for applying for an EIN.
  4. Complete the IRS Form SS-4: Fill out IRS Form SS-4, 'Application for Employer Identification Number.' You can download the form from the IRS website or complete the application online.
  5. Submit Your Application: Submit the completed Form SS-4 to the IRS. You can apply online, by fax, or by mail. Online applications are generally processed the fastest.
  6. Receive Your EIN: Once your application is approved, the IRS will issue your EIN. If you applied online, you'll receive it immediately. If you applied by fax or mail, it may take several weeks.
