Taxpayers whose ITIN is expiring and who expect to have a filing requirement in 2020 must submit a renewal application. Others do not need to take any action. ITINs with the middle digits 83, 84, 85 or 86, 87 (For example: 9NN-83-NNNN) need to be renewed even if the taxpayer has used it in the last three years. The IRS will begin sending the CP48 Notice, You must renew your Individual Taxpayer Identification Number (ITIN) to file your U.S. tax return, in early summer to affected taxpayers. The notice explains the steps to take to renew the ITIN if it will be included on a U.S. tax return filed in 2020. Taxpayers who receive the notice after acting to renew their ITIN do not need to take further action unless another family member is affected.
