South Korea's National Tax Service asked Thai tax authorities to resolve delayed tax refunds affecting Korean companies and strengthen cooperation on global minimum tax administration. During a visit to Thailand's National Tax Service on the 27th, South Korea shared its experience legislating the 15% global minimum tax and operating its reporting system. The regime applies to multinational enterprise groups with annual revenue exceeding 750 million euros when their effective tax rate in a country falls below 15%. South Korea legislated the system in December 2022 and received its first reports for the 2024 fiscal year by the end of June this year, while Thailand will implement it for the first time next year. The Korean agency presented cases involving a withholding-tax refund pending since May 2023 and a value-added tax refund delayed for several months. Thai authorities agreed to cooperate on smoother reporting and stable local operations, while the two sides agreed to establish a tax-support hotline. South Korea also urged Thailand to join an automatic information-exchange agreement for the global minimum tax.
