Federal Employer ID Number

​ (FEIN or EIN)

Federal EIN (FEIN)

The Federal Employer Identification Number (FEIN) is obtained from the Internal Revenue Service (IRS). You can register for one online, or by completing an SS-4 and mailing it in. The IRS requires a business to have an FEIN if the business:


  • Already has employees
  • Intends on hiring employees
  • Registered as a corporation or partnership (including LLC multimember)
  • Elected to be taxed as a corporation or S-Corp.



I am a sole proprietor. Do I need an EIN? 

Each business is different. Most sole proprietors identify by the owners' Social Security Number (SSN) when filing for the business.

Should I register for my Employer Identification Number first, or should I complete my registration with the Secretary of State?

It is best to register with the Secretary of State (if you intend to register with the state) before obtaining an EIN. This ensures that your business name is available when it's time to register with the IRS, State, County, and Municipal organizations. 

My business is a foreign entity. Do I need an EIN? 

Previously established out-of-state businesses have typically already registered for an EIN from the IRS. 

What is an Individual Taxpayer Identification Number (ITIN)?

An ITIN, or Individual Taxpayer Identification Number, is a tax processing number only available for certain nonresident and resident aliens, their spouses, and dependents who cannot get a Social Security Number (SSN). It is a 9-digit number, beginning with the number "9". Visit the IRS Taxpayer Identification Number page for more information.
