Getting an EIN is one of the first real steps after forming your LLC.
It sounds technical, but the process is actually simple once you understand what’s required.
Whether you’re starting a US-based business or managing an LLC from outside the US, this guide walks you through everything clearly.
What Is an EIN and Why Do You Need It?

An EIN (Employer Identification Number) is a unique 9-digit number issued by the IRS. Think of it as a Social Security number for your business.
You’ll need an EIN to:
Key Uses of EIN
- Open a US business bank account
- File taxes for your LLC
- Hire employees
- Apply for business licenses
- Work with payment processors (Stripe, PayPal, etc.)
Even if your LLC has no employees, most banks and platforms still require an EIN.
Who Needs an EIN for an LLC?
Not every LLC is required to have one, but in practice, most do.
You need an EIN if:
- Your LLC has more than one member
- You plan to hire employees
- You want to open a US bank account
- Your LLC is taxed as a corporation
- You are a non-US resident
You may not need an EIN if:
- You have a single-member LLC with no employees
- You’re not opening a business bank account
That said, even single-member LLC owners usually get one to avoid using their personal SSN.

Before you start, keep these details ready. This saves time and avoids errors.
Required Details
