The committee has already notified relevant financial institutions to submit data of American clients to see whether they comply with the Provisions of the FATCA Agreement. Non-compliant Americans will be asked to register on the website of the Internal Revenue Services before 5th of May 2014. FATCA was enacted in 2010 by the Congress to target noncompliance by US taxpayers using foreign accounts. FATCA requires foreign financial institutions (FFIs) to report to the Internal Revenue Services (IRS) information about financial accounts held by US taxpayers, or by foreign entities in which US taxpayers hold a substantial ownership interest. The financial institutions that do not both register and agree to report face a 30 percent withholding tax on certain US-source payments made to them.
Nearly 26 European countries have already signed the FATCA agreement and 19 others are in the final negotiation stage. Almost all Gulf Cooperation Council states have started taking serious step towards signing the FATCA Agreement before the set deadline, 1st of July 2014, to prevent any US penalties imposed on their financial institutions.link
