Individuals who obtained an ITIN before 2013 will be required to renew it over a staggered schedule between the end of 2016 and 2020 if they plan on continuing to use an ITIN to file a federal return.
The Protecting Americans from Tax Hikes (PATH) Act of 2015 did more than just extend the tax provisions that had expired at the end of 2014. The PATH Act also included, as part of its integrity provisions, changes to the circumstances in which an Individual Taxpayer Identification Number (ITIN) will expire.
