Do You Need a US Visa or Residency to Get an ITIN? (Myth Busted)

There's a persistent myth that an ITIN is some kind of immigration document. It isn't, and understanding the difference can save you months of confusion when you're setting up a US LLC from abroad.

What an ITIN actually is

An Individual Taxpayer Identification Number, or ITIN, is a nine digit number issued by the IRS for federal tax purposes. That's it. It exists specifically for people who need to file or be referenced on a US tax return but who are not eligible for a Social Security Number (SSN). SSNs are tied to work authorization and immigration status. ITINs are not. The IRS created the ITIN precisely so that non-residents, foreign investors, and foreign business owners could meet US tax obligations without ever needing a visa, a green card, or any US immigration status at all.

The myth versus the reality

The myth goes something like this: 'I'd need a visa or some kind of US residency to get a taxpayer number.' It's an understandable assumption because the process feels bureaucratic and government-adjacent, but it's not accurate.

The reality is simpler. The IRS asks one core question when you apply for an ITIN: do you have a valid tax reason to need one? Your passport, nationality, and immigration status are used only to confirm identity, not to determine eligibility. A founder in Berlin, Lisbon, or Warsaw who has never set foot in the United States can hold an ITIN just as legitimately as someone living in the US on a temporary visa.

You need a tax reason to get an ITIN. You do not need a visa, a green card, or a US address.

Valid tax reasons non-US founders typically have

Most European founders who end up needing an ITIN fall into one of these situations:

• You're a non-resident alien filing a US tax return, for example Form 1040-NR, because you have US-sourced income.
• You own a US LLC and need to be listed as the responsible party on certain filings, or you personally need to report distributions.
• You're claiming a reduced withholding rate under a tax treaty between your home country and the US.
• A US bank, brokerage, or payment processor requires an ITIN as part of their own tax reporting obligations, separate from the IRS requirement itself.

Note the distinction here: forming a foreign-owned single-member LLC and getting an EIN for that LLC does not by itself require the individual owner to have an ITIN. The EIN is the business's tax ID and it's obtained using Form SS-4, which explicitly allows non-US individuals to apply without an SSN or ITIN. The ITIN becomes relevant when the individual, not the business, has their own reporting obligation.

How to actually get an ITIN without a US visa

The application runs through Form W-7, submitted directly to the IRS. There is no immigration checkpoint anywhere in this process. In practice it involves:

• Completing Form W-7 with the correct reason code for why you need the ITIN.
• Providing proof of identity and foreign status, almost always a certified or notarized copy of your passport.
• Attaching the tax return or accompanying document that establishes the tax reason, unless you qualify for one of the narrow exceptions.
• Submitting by mail to the IRS in Austin, Texas, in person at a limited number of IRS Taxpayer Assistance Centers, or through a Certified Acceptance Agent (CAA) who can verify your passport locally so you don't have to mail the original.

Processing takes time and patience matters here. Errors on the reason code or missing supporting documents are the most common cause of rejected applications, not anything to do with residency status.

ITIN versus EIN, quickly

Where founders get tripped up

Two mistakes come up repeatedly. First, assuming you need an ITIN before you can get an EIN for your LLC, when in fact the EIN process for foreign owners is designed to work without one. Second, applying for an ITIN 'just in case' without a genuine tax reason attached, which the IRS will reject. If you're a foreign owner of a US LLC, the annual obligation to know about is Form 5472 filed alongside a pro-forma Form 1120, required even if the LLC had zero income, with a penalty of 25,000 dollars for failing to file. This is a business-level filing tied to the EIN, and it's separate from whether you personally need an ITIN.

This is exactly the kind of sequencing that trips up first-time founders from outside the US, and it's why Founders Credit handles LLC formation, EIN applications, ITIN applications when genuinely needed, and the US business bank account setup as one done-for-you process, so nothing gets applied for out of order or without the right supporting paperwork.
