What is an EIN?

An EIN is a unique nine-digit tax identification number assigned by the IRS to business entities operating in the United States. It's essentially a Social Security number for your business. 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 API business entity (LLC, C-Corp, etc.) is properly formed in Arkansas. You must be the owner, officer, or authorized representative to apply for an EIN.
  2. Complete Form SS-4: The application for an EIN is IRS Form SS-4. You can download it from the IRS website or complete the application online. The form requires information about your API business, such as its legal name, address, and the reason for applying.
  3. Apply Online (Recommended): The fastest way to get an EIN is through the IRS Online EIN Assistant. The online application is available Monday through Friday, from 7:00 a.m. to 10:00 p.m. Eastern Time.
  4. Apply by Fax or Mail (Less Common): You can also apply for an EIN by faxing or mailing Form SS-4 to the IRS. However, these methods take significantly longer than applying online.
  5. Receive Your EIN: If you apply online, you'll receive your EIN immediately after submitting the application. If you apply by fax or mail, the IRS will send your EIN via mail, which can take several weeks.
  6. Notify Arkansas State Agencies (If Required): In some cases, you may need to notify the Arkansas Secretary of State or the Arkansas Department of Finance and Administration about your new EIN, especially if you are registered for sales tax or other state-level taxes.
