Individual Taxpayer Identification Numbers (ITINs) will expire if not used on a federal income tax return for five consecutive years, the Internal Revenue Service announced today. To give all interested parties time to adjust and allow the IRS to reprogram its systems, the IRS will not begin deactivating ITINs until 2016.

The new, more uniform policy applies to any ITIN, regardless of when it was issued. Only about a quarter of the 21 million ITINs issued since the program began in 1996 are being used on tax returns. The new policy will ensure that anyone who legitimately uses an ITIN for tax purposes can continue to do so, while at the same time resulting in the likely eventual expiration of millions of unused ITINs.

ITINs play a critical role in the tax administration system and assist with the collection of taxes from foreign nationals, resident and nonresident aliens and others who have filing or payment obligations under U.S. law. Designed specifically for tax administration purposes, ITINs are only issued to people who are not eligible to obtain a Social Security Number.

Under the new policy:

  • An ITIN will expire for any taxpayer who fails to file a federal income tax return for five consecutive tax years.
  • Any ITIN will remain in effect as long as a taxpayer continues to file U.S. tax returns..
  • A taxpayer whose ITIN has been deactivated and needs to file a U.S. return can reapply using Form W-7.
