An ITIN number is valid for use indefinitely once issued. However, it must be used on a federal tax return at least once every three years to remain active. If not used for three consecutive years, it will expire and a renewal will be necessary. For example, an ITIN not used on a tax return for 2020, 2021, and 2022 would expire at the end of 2022. Always ensure your ITIN is active before filing a tax return.
