What’s an ITIN and Why Do You Need One?
An ITIN (Individual Taxpayer Identification Number) is issued by the IRS to individuals who aren’t eligible for a Social Security Number but still need to file U.S. taxes. It’s crucial for tax compliance, refund eligibility, and claiming dependents.
Step-by-Step ITIN Application Process

Fill out the latest version carefully. Mistakes can delay processing. - Attach Your Federal Tax Return
Unless you qualify for an exception, you must include your return with the application. - Provide Original ID or Certified Copies
A valid, original passport is preferred. Other options include a combination of ID with a photo and birth certificate. - Submit Your Application
