Taxpayers with expiring Individual Taxpayer Identification Numbers (ITINs) can get their ITINs renewed more quickly and avoid refund delays next year by submitting their renewal  application soon, the Internal Revenue Service said on Friday. Any ITIN with middle digits 83, 84, 85, 86 or 87 will expire at the end of this year. In addition, any ITIN not used on a tax return in the past three years will expire. As a reminder, ITINs with middle digits 70 through 82 that expired in 2016, 2017 or 2018 can also be renewed. For more information, visit the ITIN information page on IRS.gov.
