Tax Compliance and Financial Reporting

The Chief Financial Officer (CFO) promotes and oversees tax governance as the head of the Global Corporate Planning & Management. The Finance and Accounting Department promotes activities across the Daiichi Sankyo Group of companies in line with the “Daiichi Sankyo Group Approach to Tax” set forth as a global policy.
Across the group, we ensure that taxes are paid, tax returns are filed on time, and all required information is submitted to each jurisdiction in accordance with relevant laws and regulations. Furthermore, in order to provide clarity regarding our long-term tax position, we seek prior approval from tax authorities by using advance pricing arrangements. In fiscal year 2023, we obtained an approval of advance pricing arrangement on the therapy for a rare disease, tenosynovial giant cell tumor from both tax authorities in Japan and the United States.
As a multinational company, we also meet evolving requirements in a timely manner by closely and continuously reviewing our tax obligations across the globe. In particular, we promote efforts on the rules for documentation of transfer pricing transactions and anti-tax haven rules under the Base Erosion and Profit Shifting (BEPS) project.
In fiscal year 2023, no sanctions or other punitive measures were imposed on any member companies within the Group for any material violations of tax compliance.
