What is Form W-7?

Form W-7 is the IRS application for an Individual Taxpayer Identification Number (ITIN), a nine-digit number issued to people who have a U.S. tax filing or reporting requirement but cannot get a Social Security number. This includes nonresident aliens claiming a tax treaty benefit, resident aliens filing a return based on days present in the U.S., and the spouses and dependents of U.S. citizens or resident aliens. The same one-page form is used both to apply for a new ITIN and to renew an existing one, and the current edition is Rev. December 2024. You generally must attach Form W-7 to a federal tax return along with original or certified-copy identity documents, unless you qualify for one of the listed exceptions. With JustFill you can fill the official W-7 PDF online for free — the AI detects each field so you can type or dictate your answers, it works on scanned copies, and you never need Adobe Acrobat.

Who fills out Form W-7?

  • Nonresident aliens who need an ITIN to claim a reduced withholding rate under a U.S. tax treaty.
  • Resident aliens filing a U.S. federal tax return based on the number of days present in the United States.
  • Spouses of U.S. citizens or resident aliens who need a taxpayer number to be claimed on a return.
  • Dependents of U.S. citizens or resident aliens being claimed for tax purposes.
  • Nonresident alien students, professors, or researchers filing a return or claiming an exception.

Common mistakes to avoid

  • 1Checking more than one reason box (a–h) instead of the single box that applies, which delays or stops processing.
  • 2Sending plain photocopies of identity documents rather than the required originals or agency-certified copies, causing the application to be rejected.
  • 3Forgetting to attach the federal tax return the ITIN is needed for, when you do not qualify for one of the listed exceptions.
