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. You'll need an EIN to hire employees, open business bank accounts, and file certain tax returns.

How to Apply for an EIN

  1. Determine Eligibility: Ensure your Iowa business entity is eligible for an EIN. Generally, any entity operating as a corporation, partnership, or LLC (with more than one member or electing to be taxed as a corporation) requires an EIN.
  2. Choose Your Business Structure: Decide on the legal structure for your Iowa business (LLC, C-Corp, etc.). This decision impacts your EIN application. Iowa LLCs require a $50 filing fee to form.
  3. Gather Required Information: Collect all necessary information, including the legal name of your Iowa business, its principal address, the responsible party's name and Social Security number (or 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 Form SS-4 to the IRS. You can apply online, by fax, or by mail. Online applications are typically processed most quickly.
  6. Receive Your EIN: Once your application is processed, the IRS will issue your EIN. If you applied online, you'll typically receive your EIN immediately. If you applied by fax or mail, it may take several weeks.
