The US government created the ITIN (Individual Taxpayer Identification Number) specifically for people who are not eligible for an SSN but still need to file US taxes or comply with US financial rules. For Indians, NRIs, freelancers, students, investors, and business owners, an ITIN can be extremely useful.

This guide explains everything about ITIN in simple language, step by step, without confusion.

What Is an ITIN Number?

An ITIN (Individual Taxpayer Identification Number) is a 9-digit number issued by the Internal Revenue Service (IRS) of the United States. It is used only for tax identification purposes.

The format usually looks like this:

Copy code

9XX-7X-XXXX

Important facts about ITIN:

It is not a work permit

It does not give immigration status

It is not a Social Security Number

It is used only to file US taxes and report income

The IRS issues ITINs so that people who earn US-source income can properly pay taxes, even if they are not US citizens or residents.
