A literature assessment of five empirical studies in various regions of Indonesia shows that the influence of tax understanding, tax sanctions and service quality on Micro, Small and Medium Enterprises (MSMEs) taxpayer compliance is extremely contextual. Tax sanctions, on the other hand, are the most constant factor, with a substantial influence in all of the locations examined, suggesting that the possibility of administrative and criminal fines remains a strong deterrent to promoting compliance behavior. On the other hand, service quality gives the most varied findings, notably affecting compliance in Jepara and Samarinda Ilir, but not significantly affecting Praya, Demak and Samarinda. Tax awareness, however, generates mixed results with considerable impacts in Demak and Samarinda but no impacts in Praya. These divergences point to the fact that the efficiency of these factors is largely reliant on the regional settings, the characteristics of the respondents and the degree of uniformity of the implementation of tax policy in the field. Moreover, such variations point to the fact that MSME tax compliance is not a unidimensional construct, but a multidimensional phenomenon, influenced by complex interactions between internal factors, such as individual knowledge, perception, and motivation; and external forces, such as service quality, law enforcement, and sanctions. Therefore, uniform compliance techniques are not enough. Rather, policymakers and tax authorities need to adopt a contextual, area-based strategy that takes into account the local socio-economic conditions, literacy levels and cultural nuances to effectively increase the participation of MSMEs in the official tax system.
