What is an EIN?

An EIN, or Employer Identification Number, is like 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 business bank accounts, and file business taxes. For Idaho construction businesses, it's a key element of legitimacy and operational efficiency.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your construction business meets the IRS requirements for an EIN. Generally, this includes businesses operating as a corporation, partnership, or LLC, or those that hire employees.
  2. Choose Your Filing Method: You can apply for an EIN online through the IRS website, by mail, or by fax. The online application is the fastest and most efficient method.
  3. Complete the EIN Application (Form SS-4): Fill out Form SS-4, Application for Employer Identification Number. You'll need to provide information about your construction business, such as its legal name, address, and the reason for applying.
