The principle of public service utilizes current technological and information developments as a form of public sector innovation, especially tax service innovation. Modern technology is considered to be able to provide convenience in government performance both in the form of archives and provide convenience in providing services to the community. Public services must have links with all sectors of community life. The direction of public service delivery continues to be developed by following technological developments and prioritizing service standard norms. Public service practices need to prioritize innovation or renewal by paying attention to service standard norms in order to minimize mal-administration practices. Including the implementation of the e-filling system, it is necessary to prioritize service standard norms. This study uses a descriptive type of research using a qualitative approach. Sources of literature are the main research data such as scientific journals, books, and news. The data is processed using analytical techniques, namely: data collection (data collection), data reduction (data reduction), data display (data presentation), and conclusion drawing/verification (decision making/drawing conclusions). The use of this type of descriptive research with a qualitative approach in this study was carried out because it was in accordance with the aim of analyzing the application of public sector innovation in tax modernization which was realized through E-Filing with the Principles of the Technology Acceptance Model (TAM).
