Tax: local firms in South Korea

Kim & Chang

'Enthusiasm and eagerness to meet the needs of clients' are the core strengths of the tax practice group at Kim & Chang, which is led by key practitioners Woo Hyun Baik and Byung-Moon Jung. The team comprises an integrated pricing and customs sub-practice and offers a broad range of services including assistance with tax planning, tax advice on corporate transactions, applications for tax exemptions, applications for tax rulings and transfer pricing studies. Most impressive is the firm's litigious tax work which sees the group defending taxpayer positions up to and including the supreme court, often on issues for which there is little or no legal precedent. Tae Yeon Nam and Hae Ma Joong Kim are highly recommended. Also of note is Sang Woo Lee, who specialises in tax dispute resolution and audits.

Practice head(s):

Woo Hyun Baik; Byung-Moon Jung


The work was done by a highly engaged team with a deep knowledge and broad experience in tax‘.

Sangwoo Lee is a professional lawyer with deep knowledge on income tax, especially incomes generated from abroad. Sungweon Cho is a professional lawyer with high levels of expertise in tax lawsuits; he is eager to solve matters for the client‘.

Kim & Chang’s tax practice is the best in the market; all of team members are very highly skilled and they have wide-ranging relevant network throughout the tax world, including relationships with regulatory bodies‘.

I was impressed by Yungu Kang and Sungweon Cho. They are always accurate, up-to-date and provide good technical advice from a practical perspective. They also demonstrate superb case management and I would definitely contact them as a first choice in future‘.

Approximately 50% of the tax practice is comprised of aggressive tax litigation, with the remainder a roughly even split between tax audit work and M&A-related tax structuring and advice. A specialist transfer pricing sub-practice is another hallmark of the department; Dong Hoon Ha is the name to note on this front. Key contacts Seok Hoon Kang and Dong Soo Kim are joint practice heads.
