Service

An ITIN is a personal US tax ID for people who aren't eligible for an SSN. You don't need one to form a company or get an EIN — but you may need it for personal filing.

What an ITIN is (and isn't)

An ITIN (Individual Taxpayer Identification Number) is issued by the IRS to individuals who have US tax obligations but are not eligible for a Social Security Number.

Important: you do not need an ITIN to form a US company or to get your company's EIN. An ITIN is about you personally — for example, filing a US personal tax return or claiming a tax-treaty benefit.
