Under the background of the deep integration of the digital economy and the real economy, the demand for compound tax talents with both professional literacy and digital capabilities is increasing in the market. Tax law courses, as core courses in finance and taxation majors, are facing the dual task of connecting industry needs and realizing digital transformation. From the perspective of industry-education integration, this paper explores the reform path of digital teaching content and curriculum system of tax law courses. By analyzing the current problems such as disconnection between teaching content and industry practice, backward digital teaching methods, and imperfect curriculum system, it puts forward targeted strategies: optimizing digital teaching content based on industry needs, constructing a multi-level integrated curriculum system, innovating digital teaching methods with the help of industry resources, and improving the supporting guarantee mechanism. The research aims to promote the organic combination of tax law teaching and industry development, cultivate high-quality tax talents who adapt to the digital age, and provide reference for the reform and development of finance and taxation education.
