Sang I. Ji

Partner, New York


Sang I. Ji helps clients tackle issues relating to tax, reducing their exposure and managing complexity with clarity and directness.


Head of White & Case's Global Tax Practice, Sang Ji's practice focuses on domestic and international tax law. He has particular experience with tax issues arising from mergers and acquisitions, securities offerings, financial products, investment funds and controversies with the US Internal Revenue Service.

Sang's experience extends to stock and asset acquisitions, including tax-free reorganizations. Many of these transactions are cross-border deals that required complex structuring to accommodate the business and tax considerations of the parties involved.

Further tax issues on which Sang is able to help clients include those related to partnerships, consolidated groups, net operating losses, controlled foreign corporations, passive foreign investment companies, FIRPTA, corporate inversions and treaty benefits. He also works on the tax aspects of restructurings, joint ventures, project financings and a broad range of other matters.

Sang works extensively with issuers and underwriters around the world on a broad array of securities offerings, including income deposit securities, convertible redeemable preferred stock, structured notes and complex trust instruments. Many of these offerings have required the creation of tax-efficient structures that navigate the varied requirements of multiple taxing jurisdictions.

He also advises investment funds and investors in such funds on tax-efficient structures for investments by United States persons outside the United States, as well as investments in the United States by non-United States persons.

Clients from a range of industries including energy, financial services, insurance and technology come to Sang for his tax expertise. Notable recent transactions on which he has advised include the acquisition of Pinebridge Investments, the reorganization of the global Visa payments network, arranging the issuance and guarantee of CDN$236 billion in Canada Mortgage Bonds, and the US$36.5 billion sale of Burlington Resources, Inc.

Prior to joining White & Case LLP, Sang served as an attorney-adviser to Judge James S. Halpern of the United States Tax Court.
