The National Assembly is reviewing a bill to update rules under the International Tax Adjustment Act.
The Korea (Rep.) National Assembly has accepted Bill No. 2212654 for review on 3 September 2025, aiming to partially amend the International Tax Adjustment Act.
The proposed changes focus on strengthening the rules around taxation of foreign-related parties and ensuring compliance with international standards.
Under the bill, companies would need to provide supporting documents when requesting corrections based on arm’s length price adjustments.
Additionally, collective investment vehicles would be able to obtain residency certificates to demonstrate that the beneficial owner qualifies as a resident or domestic corporation when claiming tax benefits.
The bill also introduces a domestic surtax to enforce the 15% global minimum tax, in line with OECD administrative guidance.
Earlier, the South Korean Ministry of Economy and Finance released its 2025 tax law amendment proposal on 31 July 2025, which includes corporate tax hikes, AI investment incentives, and new international tax rules.
