The U.S. Individual Taxpayer Identification Number (ITIN): how to get one and what it is for
An ITIN (Individual Taxpayer Identification Number) is a 9-digit number issued by the U.S. Internal Revenue Service (IRS) for people who have a federal tax reporting requirement but are not eligible for a Social Security Number (SSN). It serves one purpose only — federal tax reporting: it does not authorize work, does not change immigration status, and is not a substitute for an SSN. A practical guide based only on verified official sources.
Many Uzbeks living in the United States, or earning U.S.-source income, need to file taxes — but not all of them are eligible for a Social Security Number (SSN). For exactly these cases the IRS issues an Individual Taxpayer Identification Number — the ITIN. Below, what the ITIN is, who needs it, and how to obtain one, based solely on official IRS information.
What an ITIN is
An ITIN is a 9-digit taxpayer identification number issued by the U.S. Internal Revenue Service (IRS). It looks like an SSN (formatted 9XX-XX-XXXX) and always begins with a “9.” Its sole purpose is federal tax reporting. It is not an SSN, does not authorize employment, does not provide or change immigration status, does not qualify the holder for Social Security benefits or the Earned Income Tax Credit (EITC), and is not valid identification outside the federal tax system.
Who needs an ITIN
An ITIN is for people who have a U.S. federal tax filing or reporting requirement but cannot get an SSN — regardless of immigration status. Examples: nonresident aliens who must file a return or claim a refund; resident aliens (by the substantial-presence test) who file a return; spouses or dependents of U.S. citizens or residents; and certain foreign students, professors and researchers.
How to apply: Form W-7
To get an ITIN you complete the IRS Form W-7. It is normally filed together with a federal tax return (exceptions exist for certain applicants). A return attached to a new W-7 must be filed on paper, not electronically. Documents can be submitted three ways: (1) by mail to the IRS center in Austin, Texas; (2) through an IRS-authorized Certifying Acceptance Agent (CAA); or (3) in person, by appointment, at an IRS Taxpayer Assistance Center.
What documents are required
With the application you submit documents proving identity and foreign status. They must be original documents or certified copies from the issuing agency. A passport is the only standalone document that proves both identity and foreign status; otherwise two documents are generally required.
Expiration and renewal
Per IRS rules, if an ITIN is not included on at least one federal tax return for three consecutive tax years, it expires on December 31 of that third year and must be renewed before it is used again. Renewal is done using the same Form W-7.
What an ITIN can and cannot do
With an ITIN you can file federal (and state) tax returns and, where eligible, claim certain tax credits (for example the Child Tax Credit in qualifying situations); many banks accept an ITIN to open an account. An ITIN cannot authorize work in the U.S., does not qualify the holder for Social Security benefits or the EITC, and does not serve as official identification outside the tax system. (Bank acceptance is each bank's own practice, not an IRS guarantee.)
Cost and processing time
There is no IRS fee for filing Form W-7 itself (CAAs or tax preparers may charge their own service fees — that is not an IRS charge). Per the IRS, allow about 7 weeks for notification; during peak season (January 15 – April 30) or when filing from abroad it can take 9–11 weeks.
The key takeaway
An ITIN is purely a tax tool. It confers no legal status, no work authorization and no immigration benefit, and it does not change such status. Getting an ITIN or filing taxes does not automatically affect a person's immigration case — tax and immigration are separate systems. For a specific situation, consult official IRS guidance or a licensed tax professional.
