What is an EIN?

An EIN, or Employer Identification Number, is essentially a Social Security number for your business. It's a unique nine-digit number assigned by the IRS to identify your business entity. You'll need an EIN to hire employees, open a business bank account, and file business taxes.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your Arkansas co-founder business meets the IRS requirements for obtaining an EIN. Generally, any business operating as a partnership, LLC, or corporation needs an EIN.
  2. Choose a Responsible Party: Designate a 'responsible party' – typically one of the co-founders – who will control, manage, and direct the entity and the disposition of its funds and assets. This person's information will be required on the EIN application.
  3. Complete Form SS-4: The application for an EIN is IRS Form SS-4. You can download it from the IRS website or apply online through the IRS EIN Assistant. Be prepared to provide information about your Arkansas co-founder business, including its legal name, address, and the nature of its activities.
  4. Apply Online (Recommended): The easiest and fastest way to obtain an EIN is through the IRS Online EIN Assistant. The online application is available Monday through Friday, 7:00 a.m. to 10:00 p.m. Eastern Time.
  5. Submit via Mail or Fax (If Necessary): If you prefer, you can mail or fax Form SS-4 to the IRS. However, processing times are significantly longer than applying online. Check the IRS website for the appropriate mailing address or fax number for Arkansas.
  6. Receive and Store Your EIN: Once your application is processed, you'll receive your EIN. If you applied online, you'll receive it immediately. If you applied by mail or fax, it may take several weeks. Keep your EIN in a safe place, as you'll need it for various business activities.
