Tax Administration 3.0, Digitalization, Data Analysis, Electronic Invoice, Artificial Intelligence


Governments globally acknowledge the efficient and transparent tax collection for fostering citizen fairness. Tax Administration 3.0 means a phase marked by advanced data utilization and automation, encompassing Digital Identity, Taxpayer touchpoints, Data management and standards, Tax rule management, New skill sets, and Governance frameworks. This article delves into the pivotal elements of Tax Administration 3.0, highlighting the shift from manual Tax Administration 1.0 to a comprehensive, data-driven approach, emphasizing transparency and cooperation. Central to this transformation is the role of data, facilitating innovative practices like pre-filled tax declarations, data analytics, and predictive modelling to combat fraud and enhance tax system fairness. While digitalization promises improved efficiency and taxpayer engagement, it also necessitates vigilant data security and privacy management to maintain public trust.
