South Korea is expected to gain access to financial information on its nationals from the U.S. as the two countries are close to an agreement on sharing related data, finance ministry officials said Thursday, a move expected to help Seoul's crackdown on offshore tax evasion. South Korea is currently in talks with the U.S. to accept the Foreign Account Tax Compliance Act (FATCA), under which the U.S. can ask other countries to share information on financial accounts of its individuals and entities holding more than US$50,000 and $250,000, respectively.
