In the contentious space, Kim successfully led a team that included ‘renowned’ practice co-head Seok Hoon Kang, Jeong Cheol Cho and Young Joon Chun in a Supreme Court case seeking cancellation of the VAT assessment for Korea Rail Network Authority.

The team is also a popular choice for appeals before the Tax Tribunal, and practice co-head Dong Hyun Kim, alongside Seung-Wan Chae and Hakrae Cho, is representing KG Group in various tax appeals. On the non-contentious side, the practice draws on a team of accountants to advise clients such as Qualcomm on transfer pricing issues. Other key figures include public accountant Tae Kyoon Kim, who wins praise for his ‘very logical and systematic approach’, and practice co-head Wu Cheol Song.
