Forming a US Limited Liability Company is one of the smartest moves an international entrepreneur can make. It unlocks the global banking system, provides access to top tier payment processors like Stripe, and establishes tremendous credibility for your brand.
However, once your company is officially registered, you will encounter a maze of tax acronyms. The most confusing of these are the EIN, the SSN, and the ITIN.
While almost every founder knows they need an Employer Identification Number for their business, the Individual Taxpayer Identification Number often causes unnecessary panic. Here is the absolute truth about what this number is, why the IRS issues it, and whether your new LLC actually needs one.
What is an Individual Taxpayer Identification Number?
The IRS uses a nine digit number to track taxpayers and ensure everyone pays their required share of taxes. For American citizens and permanent residents, this nine digit code is a Social Security Number.
However, foreign citizens who do not live in the United States and do not have work authorization cannot get a Social Security Number. Because the IRS still needs a way to process tax returns and track the financial activity of these foreign individuals, they created the ITIN.
In short, it is simply a tax processing number issued exclusively to foreign nationals who have federal tax reporting requirements in the United States but are ineligible for an SSN.
EIN versus ITIN: Understanding the Difference
Mixing up these two acronyms is the most common mistake international founders make. Understanding the distinction is critical for your compliance.
The EIN: This belongs to your business. It is the federal tax identification number for your LLC. You need this to open a business bank account, hire employees, and file corporate tax returns. You can absolutely obtain an EIN for your LLC without having an SSN or an ITIN.
The ITIN: This belongs to you personally. It is your individual tax identification number. It is tied to your passport and your personal identity, not your company.
Do You Actually Need an ITIN for Your LLC?
The short answer is no, you do not need one to form your LLC or to get your business EIN. However, depending on your business model and financial goals, you might need one later.
Here are the scenarios where obtaining this number becomes mandatory:
Filing a Personal US Tax Return: If your LLC is a single member pass through entity and you generate income that is legally considered US sourced, you must file a personal nonresident alien tax return using Form 1040NR. The IRS requires a personal tax ID to process this return.
Claiming Tax Treaty Benefits: If your home country has a tax treaty with the United States that lowers your withholding tax rate, you must have an individual tax ID to claim those benefits on official IRS forms.
Opening Personal US Bank Accounts: While platforms like Mercury and Relay allow you to open a business bank account using only your company EIN, traditional brick and mortar banks often require a personal tax ID if you want to open a personal checking or savings account in the United States.
The Application Process
Applying for this number requires precision. You must fill out Form W7 and submit it to the IRS along with original documentation proving your identity and foreign status, which usually means your physical passport.
Because sending your actual passport in the mail is highly risky, the IRS allows you to use a Certifying Acceptance Agent. These authorized agents can verify your passport in person or via video call, allowing you to keep your original documents while they send copies directly to the IRS on your behalf. As an IRS-authorized Certifying Acceptance Agent (CAA), Clemta is empowered to verify your identity documents remotely, saving you the risk of mailing your physical passport to the United States.
