Attention: Nearly 3 Million ITINs Expire at the End of 2018

Attention: Nearly 3 Million ITINs Expire at the End of 2018

Do you have an Individual Taxpayer Identification Number (ITIN)? These nine-digit tax processing numbers issued by the IRS are required for anyone who must file or pay taxes in the US who isn’t eligible for a Social Security Number (SSN). This year marks the third year of mandatory renewals, and with this third round of expirations, about 2.7 million ITINs expire at the end of 2018.

Which ITINs Expire at the End of 2018?

ITINs that haven’t been used at least once on a 2017, 2016, or 2015 federal tax return will expire on December 31, 2018.

Also, ITINs with middle digits 73, 74, 75, 76, 77, 81 or 82 are set to expire on December 31, 2018.

What Should You Do if Your ITIN Is Expiring?

If your ITIN is expiring at the end of this year and you have to file a 2018 tax return in 2019, you need to renew your number.

The same is true if your ITIN previously expired and you will need a valid one for filing a 2018 tax return. ITINs with middle digits of 70, 71, 72, 78, 79 or 80 have expired previously.

The IRS anticipates a rush of ITIN renewals as the end of the year approaches. So, the agency strongly recommends filing for your ITIN renewal as soon as possible to avoid potential delays or complications later on.

Renew your ITIN using an IRS Form W-7. Submit all required documentation, and don’t forget to note on the form your reason for needing an ITIN in the appropriate field. Check the form’s instructions to ensure that you fill out the form properly and to find the mailing address where it should be sent.

ITIN renewals may be filed for your entire family at the same time. The IRS aims to complete the process within 60 days.

Avoid Common ITIN Renewal Mistakes

The IRS notes certain mistakes that most often cause delays or complications in processing ITIN renewals. These include an improperly completed or incomplete Form W-7, as well as missing or insufficient supporting documentation.

Please be sure to review the form’s instructions and check over the completed form. Pay close attention to identification requirements, including for dependents.
