With the implementation of FATCA (Foreign Account Tax Compliance Act), reporting to the IRS is scheduled to begin in March, 2015. In the future, related investment and tax information will be exchanged between Taiwan and the U.S. government.
With the signing of the Intergovernmental agreement (IGA), anyone with U.S. citizenship should file all investment and financial information in Taiwan with the IRS or Financial Supervisory Commission in Taiwan.
Taiwan is also negotiating to obtain similar financial information that the Taiwan needs from the U.S. government.
