IRS Form W‑7 – Application for an Individual Taxpayer Identification Number (ITIN)

Form W‑7 is the official Application for an Individual Taxpayer Identification Number (ITIN) issued by the United States Internal Revenue Service (IRS). Taxpayers who are not eligible for a Social Security Number but need a federal tax identification number use this form.

What Is IRS Form W‑7?

The W‑7 form allows foreign individuals, residents, and certain dependents to obtain an ITIN so they can file U.S. tax returns, claim treaty benefits, or be listed on a tax return. The PDF is fully fillable, but editing it locally can be cumbersome.

FAQ
  • Who needs an ITIN?

    Non‑U.S. residents, foreign nationals, and dependents who are not eligible for a Social Security Number but must file a U.S. tax return or be listed on one.

  • Can I submit Form W‑7 electronically?

    The IRS currently requires a paper submission. You can fill it out online with Formize, then download and mail the completed PDF.

  • What documents must I attach?

    A valid, original passport is the most common. If you don’t have a passport, you can provide a combination of a national ID, birth certificate, and a US visa.

  • How long does the IRS take to process an ITIN?

    Processing usually takes 6‑10 weeks after the IRS receives a complete application.

  • Do I need to renew my ITIN?

    ITINs that have not been used on a tax return for three consecutive years will expire. Renewal is done using the same Form W‑7.

  • Is there a fee to apply for an ITIN?

    There is no fee to the IRS, but if you use an Acceptance Agent, they may charge a service fee.

  • Can I correct a mistake after mailing?

    If you discover an error, you must submit a new, complete Form W‑7 with the correct information.

  • What if I lose my ITIN?

    You can request a copy of your ITIN by calling the IRS at 1‑800‑829‑1040 or by submitting a new Form W‑7.

  • Is Form W‑7 the same as a Social Security Number?

    No. An ITIN is for tax purposes only and does not provide work authorization or Social Security benefits.

  • Will Formize store my personal data?

    Formize processes the PDF in a secure, temporary session and does not retain any personal information after you download the completed form.
