Starting a business in the United States as a non-resident? An Employer Identification Number (EIN) is your essential first step. Whether you’re pursuing LLC formation or setting up any other business entity, understanding the EIN process is crucial for success. This guide covers everything you need to know.
What Is an EIN?
An EIN is a nine-digit number assigned by the IRS – think of it as your business’s Social Security Number. It’s essential for opening bank accounts, hiring employees, filing taxes, and establishing credibility with U.S. partners.
Why Non-Residents Need an EIN
- Open a U.S. business bank account
- File business tax returns (business tax preparation)
- Hire employees in the U.S.
- Establish business credibility
- Apply for business licenses and permits
- Build business credit separate from personal finances
Who Needs an EIN?
You MUST have an EIN if you:
- Form an LLC, Corporation, or Partnership
- Have or plan to hire employees
- Operate as a multi-member LLC
You SHOULD get an EIN even if not required:
- Operating a single-member LLC (for banking)
- Protecting privacy (avoid using personal ITIN)
- Building professional business credibility
