Many people know what a Social Security Number (SSN) is but may not be familiar with an EIN. An Employer Identification Number (EIN) is also known as a Federal Tax Identification Number and it’s used to identify a business entity. Generally, businesses need an EIN.  The IRS uses the number to identify taxpayers that are required to file various business tax returns. EINs are used by employers, sole proprietors, corporations, partnerships, non-profit associations, trusts, estates of decedents, government agencies, certain individuals, and other business entities. 

An EIN It is a nine-digit number that is unique to every business. Many banks also require an EIN before businesses can apply for business accounts and establish lines of credit, which can be essential for startups. EINs help to legitimize businesses in the eyes of institutions that want to verify them, so the EIN becomes the business’s ID. Typically, getting an EIN is one of the first steps when starting a business.

How do you know if your business needs an EIN? 

Determine your eligibility:

  • You may apply for an EIN online if your principal business is located in the United States or U.S. Territories.
  • The person applying online must have a valid Taxpayer Identification Number (SSN, ITIN, EIN).
  • You are limited to one EIN per responsible party per day.
    • The “responsible party” is the person who ultimately owns or controls the entity or who exercises ultimate effective control over the entity. Unless the applicant is a government entity, the responsible party must be an individual (i.e., a natural person), not an entity.

Take a look and complete this questionnaire from the IRS to help you determine your eligibility.
