If you need to file a U.S. tax return or claim a tax benefit but aren’t eligible for a Social Security Number (SSN), you may need an Individual Taxpayer Identification Number (ITIN). At Bluewings Tax, we guide individuals and families through the ITIN process every day. This guide explains what an ITIN is, who needs one, and how to apply with confidence.
What is an ITIN?
An ITIN is a tax-processing number issued by the Internal Revenue Service (IRS) to individuals who have U.S. tax-filing or reporting obligations but do not qualify for an SSN. It allows you to comply with U.S. tax law and, where applicable, claim certain benefits and credits. An ITIN is used strictly for federal tax purposes and does not authorize work in the U.S. or affect immigration status.
Who typically needs one?
- Non-resident individuals required to file a U.S. tax return
- Foreign nationals with U.S.-sourced income
- Dependents or spouses of U.S. citizens and residents
- Individuals claiming benefits under a tax treaty
Documents you’ll generally need
Applications are submitted using IRS Form W-7 alongside your federal tax return (unless you qualify for an exception). You’ll also need to prove your identity and foreign status — most commonly with a valid passport. Additional documentation may apply depending on your circumstances.
