The rapid development of the digital economy has brought new challenges to global tax administration, and traditional tax systems are facing numerous difficulties. As an important part of global tax reform, the "two-pillar solution" is of great significance in addressing tax issues in the digital economy. This paper first provides a brief overview of the two-pillar solution and its main contents. It then examines the issue of tax certainty in the digital economy, analyzes the importance of tax certainty for the digital economy, and the challenges it faces. Subsequently, policy recommendations are presented to address tax certainty issues in the digital economy, including international cooperation and coordination, improving tax data collection and information exchange, and promoting self-regulation and compliance in the digital economy. Finally, by analyzing the example of the EU digital tax proposal and the progress and implementation of international tax reform, the paper summarizes the importance of tax certainty in the digital economy, the prospects and challenges of the two-pillar solution, policy recommendations, and future prospects. This paper aims to provide ideas and references for researching tax issues in the digital economy and its solutions, in order to promote the reform and upgrading of the global tax system.
