The ITIN is not a permanent document and must be renewed periodically. The IRS requires you to renew your ITIN if you haven’t used it in the last three years or if it is about to expire. Renewal is essential to continue filing taxes and accessing tax benefits.

The renewal process is similar to the initial application. You must complete Form W-7 and submit it along with the required documents, such as your passport or birth certificate. Make sure you submit the application well in advance to avoid interruptions in your tax processing.

If you have questions about the process, you can seek help from a certified tax preparer or consult the IRS website. Keeping your ITIN valid is key to maintaining your finances in order and complying with the law.
