ITIN Applications and Renewals: What You Need to Know

Let's start with the basics. An ITIN, or Individual Taxpayer Identification Number, is a nine-digit number issued by the IRS to individuals who must comply with U.S. tax law but aren't eligible for a Social Security number (SSN). This includes nonresident aliens, international students, and specific other non-citizen individuals. It's essentially a tax ID number.

Why Do You Need an ITIN?

You might need an ITIN for various reasons, including:

  • Filing U.S. federal tax returns
  • Claiming tax treaties
  • Claiming tax refunds
  • Opening a U.S. bank account (though this isn't always necessary)
How to Apply for an ITIN

Form W-7, Application for IRS Individual Taxpayer Identification Number, is required to obtain an ITIN. You must also supply original or certified copies of identifying documents to prove your identity and foreign status. Foreign tax returns, passports, and other official documents are examples.

Important: Most W-7 forms require a complete U.S. federal tax return. It's usually required, with exceptions.

Renewing Your ITIN

If you file a U.S. tax return every three years, your ITIN is valid forever. After three years without use, your ITIN expires on December 31.

Your ITIN renewal process is comparable to applying for a new one. If you're renewing an ITIN, send Form W-7 with the relevant documentation and your most recent U.S. tax return.

Tips for a Smooth Process
  • Gather required documents: Before applying, gather all necessary documents.
  • Check mistakes twice: Check your application for errors that could delay it.
  • Allow enough time: Plan ahead, as the IRS can take weeks to complete ITIN applications.
  • Consider professional help: Consult a tax professional if you need help or have questions.
Common Mistakes to Avoid
  • Failure to provide accurate or full documentation can delay your application.
  • File status errors: Choose the relevant tax return filing status.
  • Math errors: Correct errors in your computations to avoid delays or extra scrutiny.
