IRS Notice CP-48 is sent to notify a taxpayer that it is time to renew your Individual Taxpayer Identification Number (ITIN).

All ITINs not used on a federal tax return at least once in the last three years will no longer be valid for use on a tax return. Additionally, ITINs issued before 2013 with middle digits of 73, 74, 75, 76, 77, 81, or 82 (Example: (9XX-73-XXXX) will expire January 1, 2019. ITINs with middle digits 70, 71, 72, 78, 79 or 80 expired in 2016 & 2017. All expired ITINs must be renewed before being used on a U.S. tax return. No action is needed by ITIN holders who don’t need to file a tax return next year. Also, there are new documentation requirements when applying for or renewing an ITIN for certain dependents. Refer to the Form W-7 instructions for further requirements.

A return filed with an expired ITIN will be processed, but any credits claimed applicable to the expired ITIN will not be allowed. The taxpayer will receive a notice from the IRS explaining the change(s) made to their tax return and that the ITIN must be renewed. Once the ITIN is renewed, any credits previously not allowed will be reconsidered at that time. Until the ITIN is renewed, the taxpayer will be subject to interest and penalties for any tax owed as a result of disallowed credits.

Once an ITIN is assigned, it belongs to that taxpayer, unless the ITIN has been revoked. When an individual renews their ITIN, the previously assigned number is renewed.
