Taxpayers with expiring Individual Taxpayer Identification Numbers should submit their renewal applications as soon as possible. Failing to renew them by the end of this year will cause refund and processing delays in 2019.
ITINs are used by people who have tax filing requirements under U.S. law but are not eligible for a Social Security number. The IRS mailed more than 1.3 million letters to taxpayer households that includes someone with an ITIN to remind them to renew. Here are details about whose ITINs are expiring and how someone renews their ITIN.
In addition to English and Spanish, ITIN materials are available in Chinese, Korean, Haitian Creole, Russian and Vietnamese.
