Taxes are not only a cornerstone of national governments’ provision of local infrastructure and public services, but also an important source of funding to attain global sustainable development goals. To meet changes in global tax environment, increasing complexity in cross-border transactions and global anti-avoidance trends, WT continues to interact and cooperate with tax authorities in countries where it operates.
 

Facing the trend of international tax equity, WT implements corporate governance and shapes a corporate tax culture by formulating tax governance and transfer pricing policies, while taking into account the overall operational development and the creation of operating profits. The policies are reviewed annually to reflect international tax trends, and the need for revisions evaluated. WT files honestly in accordance with the regulations of each location where it operates, and make proper use of applicable government tax incentives.
 
WT commits to reducing its tax burden through transparent tax arrangements, ensuring that the Group’s tax strategy aligns with international anti-tax avoidance principles and corporate social responsibility. By implementing lawful and compliant tax planning, WT upholds tax transparency and maintains strong cooperative relationships with local tax authorities to jointly foster a fair and competitive business environment.
 
In response to the implemented Controlled Foreign Corporation (CFC) system, WT has adjusted its organizational structure to comply with the international anti-avoidance trend for tax fairness, reorganized its substantive operating affiliates registered in countries with low tax burdens, and prudently assessed the impact of the taxation policy on the Group. It also keeps close watch on any legislative news.
 
Tax irregularities or unethical matters can be reported internally and externally through WT’s exiting whistleblower mechanism. All tax information disclosed in relevant public channels, such as annual reports at the shareholders’ meeting, is derived from financial statements certified by an accounting firm.
 

WT established its tax policy in 2025, which was approved by the Board of Directors. Please refer to the Tax Policy and Management Guidelines for further details.
 
 
 
Tax payment situation
WT’s effective book income tax rate in 2025 was 22.03%, which is higher than Taiwan’s statutory corporate income tax rate of 20%. This was primarily due to the management’s decision to retain a portion of the current-year earnings instead of distributing them, in order to support the group’s future operating growth and funding needs, resulting in an additional tax on undistributed retained earnings.
