Tax issues arise in a wide variety of situations, including M&A, restructuring, and cross-border and financial transactions, whether in complex specialized transactions or in the ordinary course of business. We advise clients on tax issues from the planning stage onward in order to minimize tax risk, and in situations such as developing a new line of business we liaise with tax authorities to clarify tax treatment. In addition, as the economy and internationalization advance, difficult tax issues have increased in number, and there are an increasing number of cases where the tax authorities and taxpayers disagree on the appropriate tax treatment. In such cases, we represent clients throughout the entire process, from the authorities' investigation through to administrative appeals and litigation against the tax authorities.

Particularly in recent years, there have been an increasing number of cases where even at the tax investigation stage the use of a law firm has been necessary in addition to the use of a tax advisory firm, because of the different perspective of the two professions. We have been involved in many cases where the tax authorities withdrew their opinion after we submitted our opinion.
