Today the IRS reminded taxpayers with expiring ITINs to submit their renewal applications as soon as possible. Failing to renew an ITIN by the end of the year may cause both a refund and processing delay of any 2017 tax return filed once the new tax season starts.
The IRS mailed letters over the summer to more than one million taxpayers whose ITINs are set to expire. Specifically, taxpayers with ITINs with middle digits 70, 71, 72, or 80, and any ITIN that has not been used on a federal tax return at least once in the past three years (2014, 2015, and 2016), will expire at the end of this year. Affected taxpayers should submit a renewal application as soon as possible, and no later than December 31, 2017.
