Information for Individuals

Under FATCA, U.S. taxpayers with specified foreign financial assets that exceed certain thresholds must report those assets to the IRS. This reporting is made on Form 8938, which taxpayers attach to their individual federal income tax return. To help individuals understand how FATCA may impact their filing and reporting responsibilities, they have redesigned the IRS website and made it easier to navigate. The main page for individuals is found at this link: From this main page, the user may click on additional hot links, depending on the topic. For example, there is a chart available (linked from this main page via a hot link) which describes types of foreign assets which may be reportable under the FATCA rules. On the right side of this main page under the heading “Summary of Form 8938 Requirements” is another hot link to a document titled “Summary of FATCA Reporting for U.S. Taxpayers.” This document provides the best summary of the filing and reporting responsibilities for individuals.

Information for Foreign Financial Institutions

FATCA will require foreign financial institutions to report directly to the IRS information about financial accounts held by U.S. taxpayers, or held by foreign entities in which U.S. taxpayers hold a substantial ownership interest. Foreign Financial Institutions looking for information on this topic may visit the IRS website at: From this main page, the user may click on several hot links to find specific information related to FATCA regulations and guidance, the registration process, and schema requirements.

The Treasury Inspector General for Tax Administration (TIGTA) is responsible for oversight of IRS activities and for maintaining integrity in the U.S. Federal tax system. Fraud, waste, and abuse in Federal tax administration are unfair to all U.S. taxpayers and can take a variety of forms. TIGTA’s oversight includes targeted audits, programmatic inspections and evaluations, and both criminal and administrative investigations of potential fraud, waste, and abuse. Examples include:

  • Attempts by taxpayers to bribe IRS personnel;
  • Assaults or threats by taxpayers against IRS employees or facilities;
  • Theft of IRS tax remittances;
  • Impersonation of the IRS organization or IRS personnel in schemes involving the Internet or the mail to obtain personal financial information;
  • IRS employees who misuse their position for personal gain;
  • Outside contractors defrauding the IRS through false claims, deceptive contract methods, and other fraud;
  • Circumstances that could impede or hinder compliance with Federal tax laws and regulations; and,
  • Apparent abuses of taxpayer protection and rights.

Please report any information that you may have related to potential fraud, waste, and abuse to the TIGTA Hotline at

The IRS is implementing significant changes made to the ITIN program under the PATH Act of 2015.  The new law means that any ITIN not used on a federal tax return at least once in the last three years will no longer be valid as of January 1, 2017 for use on a tax return unless the taxpayer renews the ITIN.  In addition, all ITINs issued prior to 2013 will begin to expire this year and taxpayers will need to renew them.

The first pre-2013 ITINs that will expire are those with middle digits of 78 and 79 (Example:  9XX-78-XXXX).  The renewal period for these ITINs began October 1, 2016.  The IRS began to mail letters to this group of taxpayers in August to inform them of the need to renew their ITINs in order to file a tax return, and explain the renewal steps.  The IRS will announce the schedule for expiration and renewal of ITINs that do not have middle digits of 78 and 79 at a future date.

If taxpayers have an expired ITIN, not renewed before filing a tax return next year, they might face a refund delay and be ineligible for certain tax credits, such as the Child Tax Credit and the American Opportunity Tax Credit, until they renew the ITIN.  More information is available on the ITIN page at
