Notice 2013-43 provides a six-month extension for when withholding under the Foreign Account Tax Compliance Act (FATCA) will begin (i.e., payments after June 30, 2014) and for implementing new account opening procedures as well as related
requirements to comply with FATCA.
This reflects comments from US withholding agents and Foreign Financial Institutions that Intergovernmental Agreements were the appropriate solution to the legal conflicts that might otherwise impede compliance with FATCA and that they were a more effective
and efficient way to implement cross-border tax information reporting.
