If you’re planning to start a business in the United States — whether you're a U.S. resident or an international founder — one of the first things you’ll need is an EIN number USA. But what exactly is an EIN? Why is it important? And how can you apply for one as a non-resident?

This guide breaks it all down in simple, beginner-friendly language. We’ll walk you through what an EIN is, why you need it, how to apply for it, and how services like USAIndiaCFO can make the entire process easy and stress-free — especially for Indian founders and global entrepreneurs.

What is an EIN Number in the USA?

EIN stands for Employer Identification Number. It’s also known as a Federal Tax Identification Number, and it’s issued by the Internal Revenue Service (IRS) to uniquely identify your business.

Think of it as the business version of a Social Security Number (SSN). It’s a 9-digit number that looks like this: 12-3456789.

Although it’s called an “Employer” Identification Number, you don’t need to have employees to get one. In fact, almost every U.S.-based business needs an EIN, regardless of size.

Why Do You Need an EIN?

There are several reasons why your business will need an EIN number USA, even if you're a solo founder:

1. To Open a U.S. Business Bank Account

Banks require an EIN to open an account for your business. Without it, you can’t legally hold or transfer money under your company name in the U.S.

2. To File Federal and State Taxes

The IRS uses your EIN to track your company’s tax filings. It’s required for submitting your federal tax returns and, in many states, your state returns as well.

3. To Hire Employees in the U.S.

If you plan to grow your team in the future, you’ll need an EIN before you can onboard any employees.

4. To Work with U.S. Vendors and Payment Gateways

Services like Stripe, PayPal, and Amazon often ask for an EIN when setting up business accounts.

Who Needs an EIN?

Whether you’re a U.S. citizen, a resident, or a non-resident entrepreneur, you may need an EIN if you:

• Form an LLC or Corporation in the U.S.

• Operate as a sole proprietor with employees

• Have a U.S.-based partnership

• Withhold taxes on income (for non-resident aliens)

• Run a trust, estate, or nonprofit organization

In short: If you’re forming a U.S. business entity, you’ll almost always need an EIN.

How to Apply for an EIN (Especially as a Foreign Founder)

Now that you know why it’s important, let’s look at how to get your EIN number in the USA.

Step 1: Form Your U.S. Business Entity

Before applying for an EIN, you must first register your business — such as an LLC or Corporation — in the U.S. state of your choice (commonly Delaware or Wyoming).

Step 2: Complete IRS Form SS-4

The IRS uses Form SS-4 to process EIN applications. It includes details like:

• Legal name of the business

• Type of entity

• Name and address of responsible party

• Reason for applying (e.g., “Started a new business”)

Step 3: Submit Your Application to the IRS

There are four ways to apply for an EIN:

• Online (only for U.S. citizens or residents with an SSN or ITIN)

• Fax

• Mail

• Phone (for international applicants)

⚠️ Challenges for Non-U.S. Residents:

If you don’t have a Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN), you can’t use the IRS online portal. Instead, you’ll need to:

• Fill out Form SS-4

• Indicate you’re a foreign applicant

• Call the IRS or fax the form

This can be time-consuming and confusing — which is why many founders choose to work with experts like USAIndiaCFO.
