If an Individual Taxpayer Identification Number (ITIN) was not included on a U.S. federal tax return at least once for tax years 2018, 2019, and 2020, the ITIN will expire on Dec. 31, 2021.
As a reminder, IT INS with middle digits 70 through 88 have expired. In addition, ITINS with middle digits 90 through 99, IF assigned before 2013, have expired. Individuals who previously submitted a renewal application that was approved, do not need to renew again.
