The ITIN program was created on July 1, 1996 for the purpose of allowing tax return filing by individuals without a Social Security Number (SSN). Receiving an ITIN does not in itself confer the right to work and receive income in the United States.[3] ITINs are also used by real estate brokers to facilitate mortgages for unauthorized aliens.[4] In addition to use by unauthorized aliens, ITINs are used by foreign investors in United States real estate. Such investors need ITINs in order to file federal and state tax returns to report rental income.
In 2006, 1.4 million people used ITINs when filing tax returns. Federal tax law generally prohibits the IRS from sharing data with other government agencies, including the Department of Homeland Security (DHS), assuring unauthorized aliens[5] that the tax information will be confidential and generally will not be used to initiate removal procedures.[6][7]
