Recently, the "Guidelines for Lawyers Handling Tax Law Service Business," specifically developed by four lawyers from Huashui, namely Liu Tianyong, Zhang Qian, Wang Qiang, and Jiang Zheng, has been published in the "Guidelines for Lawyers' Business Operations (Volume 4)" (Peking University Press, 2022) and distributed nationwide. The guidelines cover seven chapters and 25 sections, totaling over 45,000 words, addressing topics such as "Year-round Tax Advisory Services," "Lawyers Providing Preferential Application Services for Enterprises," "Enterprise Special Tax Planning Services," "International Tax Law Services," "Personal Tax Law Services," "Tax Dispute Legal Services," and "Tax Criminal Litigation Legal Services." The revision and publication of these guidelines took one and a half years, involving multiple rounds of discussions, marking the third revision as per the requirements of the All China Lawyers Association. This updated edition of the guidelines provides a comprehensive reflection of the latest developments in the field of tax law services, playing a significant role in elevating the professional standards of tax lawyers, standardizing their practice, preventing professional risks, and guiding the development of the domestic tax lawyer industry.
