  • ITIN is a 9-digit number that begins with the number 9
  • Has a range of 70 – 88, 90 – 92, and 99 – 94 in the fourth and fifth digits

When should I use an ITIN?

An ITIN’s  purpose is to help you comply with U.S. tax laws regardless of your immigration status.

How do I apply for an ITIN Number?

In order for you to apply for an ITIN, you must complete form W-7 which is the application for IRS Individual Taxpayer Identification Number.

This form is attached and mailed along with your federal tax return to the IRS. Once received, it usually takes the IRS 6 to 8 weeks to complete the qualification process and issue your ITIN.

Does an ITIN expire?

Yes it does expire.

According to the IRS, ITINs that have not been used on a tax return for tax years 2017, 2018 or 2019 will expire December 31, 2020. Additionally, ITINs with middle digits 88 (For example: 9NN-88-NNNN) will expire December 31, 2020. Those with middle digits 90, 91, 92, 94, 95, 96, 97, 98 or 99, that were assigned before 2013 and have not already been renewed, will also expire at the end of 2020.
