Abstract

Digital tax administration has become a key instrument for enhancing transparency, accountability, and institutional effectiveness, directly supporting Sustainable Development Goal (SDG) 16 on Peace, Justice, and Strong Institutions. This study investigates individual taxpayers’ acceptance and continued use of tax e-filing in Indonesia, where adoption remains inconsistent despite mandatory implementation. Drawing on the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2), this study develops an extended model by incorporating system quality, information quality, and perceived risk from the Information Systems Success Model. A quantitative explanatory design was employed, using data from 262 individual taxpayers in Indonesia. The data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The findings reveal that performance expectancy, effort expectancy, social influence, facilitating conditions, and system quality significantly influence behavioral intention, which in turn strongly predicts actual system use. In contrast, perceived risk demonstrates a negative effect on behavioral intention, while information quality shows a positive but comparatively weaker influence. The results highlight that successful tax e-filing adoption is not only a technological issue but also an institutional and behavioral phenomenon. The study contributes to SDG 16 by demonstrating how effective digital tax systems enhance institutional trust, compliance behavior, and governance capacity. It further provides practical implications for policymakers to improve system quality, strengthen digital trust, and reduce perceived risk to promote sustainable e-government adoption.
