The Tax Authority of Korea introduced new forms for country-by-country (CbC) reporting and for the advance notification for recognizing the company of a multinational group as the “reporting entity.”
A Master file as well as a  Local file will have to be submitted by all domestic corporations and foreign corporations with Korea-source income with Sales revenue exceeds KRW 100 billion (approximately U.S. $89 million) and the volume of cross-border related-party transactions exceeds KRW 50 billion (approximately U.S. $44.4 million) for fiscal years beginning on or after 1 January 2016. Both files have to be filed with the head of the tax office having jurisdiction over the place where the tax payment is remitted, within 12 months from the fiscal year-end.
The CbC report is required to be submitted by ultimate parent company when the earlier year’s consolidated sales revenue exceeds KRW 1 trillion.
The tax authority also updated the rules on the arm’s length interest rate applicable for loan transactions between a resident and a foreign related-party.
