Question: do itin numbers have to be renewed?
Answer: 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.
