Checking your ITIN application status allows you to track the progress of your application and determine if it has been approved or denied. An ITIN, or Individual Taxpayer Identification Number, is a tax processing number issued by the Internal Revenue Service (IRS) to individuals who are not eligible for a Social Security Number (SSN) but who are required to file a U.S. tax return.
Knowing your ITIN application status is important because it allows you to plan accordingly. If your application is approved, you will receive your ITIN in the mail within 7 to 10 weeks. If your application is denied, you will be notified by the IRS and given the reason for the denial. You can then take steps to correct the error and resubmit your application.
