Most people, including some IRS personnel, call it an EIN number. But the “N” in the acronym stands for “Number,” so it should be referred to simply as an “EIN,” unless you mean to say “Employer Identification Number Number,” which is just silly.
The EIN is a federal tax identification number used by the IRS to identify most businesses. An EIN number is generally tied to a social security number so that if a tax debt is incurred, the IRS can track down a “responsible party” for payment. If your business is not considered a separate entity for tax purposes and you will only be required to file an individual 1040 tax return, such as in the case of a sole proprietorship, you do not need an EIN. However, if any of the following factors apply to you, then an EIN is needed:
- You have employees
- Your business is a partnership or corporation
- You are required to file employment tax returns
- You are required to file excise tax returns
- You are required to file alcohol, tobacco and firearms returns
- You withhold taxes on income, other than wages, paid to a non-resident alien
- You have a Keogh plan
- You are involved with any type of organization listed here
You do not need a tax attorney to help you apply for an EIN — it is easy and free. The best way to obtain an EIN is to apply online. But you may also apply by fax, phone, or mail if you insist on doing it the hard way.
