01What is an EIN?
Social security numbers also have nine digits, but can be easily distinguished from EINs as they are done in the format 123-45-6789 (note they both have the same numbers but different placement of hyphens.)
02What is an EIN Used For?
An EIN serves a purpose for a business similar to that of a social security number for an individual. An EIN is used on tax returns, business licenses and business permits, and any applications or forms that require you to fill in an IRS number to specifically identify your business.
You can also use an EIN when you open a business bank account to help further separate your business and personal expenses.
03Who Needs to Have an EIN?
All employers, no matter how small the business is, with one or more part-time or full-time employees, must have an EIN.
If you pay contractors or anyone for services valued at more than $600 in a calendar year, you may also need to get an EIN.
Certain business structures require you to obtain an EIN. For example, anyone who registers as a limited liability company, corporation, partnership, or joint venture must have an EIN.
04Does a Sole Proprietorship Need an EIN?
If you do not have any employees, neither you nor your sole proprietorship is required to have an EIN. In fact, the IRS generally prefers you to use your social security number when you own a sole proprietorship.
However, even sole proprietorships, if you ever hire any employees, must have an EIN.
Tip: If you plan to use an EIN to differentiate between your personal and business finances, you should have an EIN before you apply for business permits.

06When You Might Need a New EIN
In general, if you change your business structure, you will need a new EIN. Also, if you are a sole proprietor and file for bankruptcy, you will need to have an EIN if you did not have one before.
If you were operating as a sole proprietor and incorporate your business, add a business partner or purchase or inherit an existing business, or you are now operating as a sole proprietorship, you will need a new EIN.
There are also many instances in which existing corporations, partnerships, and limited liability corporations need to apply for a new EIN; you can learn more about some of these situations in "When Your Business Needs a New Employer ID Number."
