The US Internal Revenue Service (IRS) announced that a number of Individual Taxpayer Identification Numbers (ITINs) will expire by December 31, 2018. The affected ITINs include the middle digits 73, 74, 75, 76, 77, 81, or 82.  In addition, ITINs not used at least once on a federal tax return in the past three years will also expire.

Even though these expired ITINs can still be used on federal tax returns for tax year 2018, certain tax credits will be disallowed. The distribution of refunds will also be delayed.

The affected taxpayers and any affected family members may renew their ITINs. Taxpayers with expiring or previously expired ITINs can renew the ITINs for their entire family at the same time, even if only one ITIN is expired or expiring. To renew an ITIN, taxpayers must complete and submit Form W-7, Application for IRS Individual Taxpayer Identification Number.
