IRS Form W-7 - Application for IRS Individual Taxpayer Identification Number
Form W-7 is the IRS Application for an Individual Taxpayer Identification Number (ITIN). Use it when you need a tax identification number but are not eligible for a Social Security Number.

Plain English
If you have U.S. tax filing obligations and you can’t get a Social Security Number, you fill out this short paper to ask the IRS for an ITIN. The IRS will give you a nine‑digit number that works like a SSN for tax purposes.
Submission Date
- Filing date: File the W‑7 with the first tax return that requires an ITIN, or any time you need an ITIN for a later filing, before the return’s due date.
- Preparation window: collect IDs, supporting records, and signatures in advance.
- Final review: verify names, dates, and required fields before submission.

What this form is for

- If you are a resident alien with a SSN, file Form SS‑5 instead.

✓ Verify SSN eligibility first
Non‑resident with no tax filing
No tax return required
✓ Confirm exception eligibility
Deadline or filing window
The W‑7 must be filed with the tax return it supports, so its deadline aligns with the return’s due date (typically April 15). If you request an extension for the return, the ITIN request can be submitted by the extended deadline. No separate statutory deadline exists for the W‑7 alone.
