What is EIN?

All companies in the US need to have a registration ID called Employer Identification Number (EIN) designated by the IRS. Obtaining the EIN is one of the necessary steps to do business in the country.

The EIN will be your company’s tax ID, as it’d be used to record transactions carried out in the US and ensure that taxes are paid correctly. This document can be requested by international entrepreneurs who wish to incorporate their business in the United States

In addition, the EIN is usually required by banks when opening American business bank accounts. This would be the only tax ID number required by Globalfy to open your US bank account from abroad. No social security number or ITIN is required. To apply for your EIN, complete our form and start the process

Why do I need an EIN number?

Registering your company with an EIN is a must for most businesses. Now, check out the exact instances in which it is mandatory according to the IRS:

  • Hiring employees: The EIN will be used to track the payroll taxes for all your team members. 
  • Opening a corporation: As a separate entity from its members, corporations have their debts and obligations when it comes to taxes. 
  • Operating a partnership: Even though income and expenses generated by the partnership are passed to the partners’ individual tax returns, this process has to be filed in the company’s tax return.
  • Owning a personal service company: Companies that have personal services performed by the owner as their primary activity may need to have an EIN. Services such as ​​accounting, consulting, architecture, engineering, health, and law are included. 
  • Being involved with organizations of the following types: Trusts, Estates, Real estate mortgage investment conduits, Non-profit organizations, Farmers’ cooperatives, and Plan administrators.

When establishing a business in the US with a structure other than a sole proprietorship, you will need to have an EIN. Though, even in these cases, this documentation can bring benefits to your company. Many entrepreneurs choose to request their EIN confirmation letter from the IRS to have more credibility within their industries. 

Benefits of having an EIN

Now that you know what is EIN and why I need an EIN number, let’s talk about the benefits of having one. Even though this is not required for every business, having an EIN confirmation letter will help you open and operate your company in the US

  • Open a business banking account. Having a bank account for your business is essential to take your operation to the next level. Most banks will ask for your EIN to open a business account. 
  • Help in your business tax deductions. Some expenses have fewer chances of being audited if you have an EIN;
  • Separate your business finances from personal finances. Other than opening a business account, the EIN can help prevent identity theft. 
  • Get a business loan. Usually, lenders don’t require an EIN to give your company a loan, but this document can help with your business credit. 
  • Build trust. Having an EIN will add credibility to your work with clients and vendors.

Besides EIN, what are other kinds of tax ID?

In addition to legal entities, individuals are also identified by tax ID numbers. The social security number (SSN) and Individual Tax Identification Number (ITIN) are respectively used to identify US citizens and foreigners or non-residents


The SSN is an identification number for US citizens. For foreigners, an SSN is not required for essential services such as opening bank accounts, starting a business, or school records. 


For those who do not live in America and some US resident foreigners, the ITIN is used to file an income tax application in the US. In practice, this documentation is for people who have some kind of residence or legal work in the country to be able to declare their taxes. 

In addition to the EIN, depending on the structure and organization of your company, LLC or C Corp, owners may be required to file their individual US income tax. Thus, it is necessary to obtain an ITIN to make the mandatory declarations as an individual in the United States.
