The Employer Identification Number is something so ingrained in our daily life that we assume in some way or another that we know everything about it. But is it so?

What Is An EIN?

What Is An EIN

Let’s start with the only possible principle, which cannot be other than the definition of the concept. EIN stands for Employer Identification Number. With these three acronyms, we refer, fundamentally, to the code used to identify employers for tax purposes. It is a mandatory code for a business entity in any action of a tax nature. The employer uses it for tax purposes.

We are talking, after all, about a kind of guarantee when doing business. Think about it: the EIN is an official code endorsed by the State and linked to a registered office (IRS). Therefore, it can be traced to verify its authenticity and, consequently, to know if the person with whom we are going to do business is legitimate.

Is the EIN the Same as The TIN and the SSN?

Yes … But with specific nuances.

The TIN or Taxpayer ID Number is a unique code assigned to taxpayer citizens. The IRS issues TIN. The EIN and SSN are two different types of TIN provided by IRS and SSA, respectively.

The SSN (Social Security Number) is the reference document for natural persons with American nationality. They can be permanent or temporary residents. It is a nine-digit number provided by the US Government.

Whereas, EIN can be described as the SSN for the business person. It is also a nine-digit code issued by the IRS. The EIN helps to identify the entity or person doing business. EIN is also called the FEIN (Federal Employer Identification Number) or FTIN (Federal Tax Identification Number).

When is the EIN Used?

The EIN is used to identify a business entity or person when carrying out any procedure that has tax relevance. This is why every professional or entrepreneur must state it in the invoices and the supporting documents generated during its fiscal year.

That is the basis. But there are also other cases in which you will need to use the Employer Identification Number:

  • If you have several employees
  • IF your company or business is in a partnership, LLC or corporation
  • Deeds or documents for the constitution, transmission or extinction of real rights over real estate
  • In the case of withholding taxes
  • Business Bank account
  • License or permit of business
  • Insurance or financial operations of insurance entities
  • Contributions to pension plans or perceptions of those same plans
