These factors were expected to trigger the taxpayer attitude which will be impact on their behavioral intention. Using a qualitative research approach, an interview with 16 individual taxpayers with certain criteria was conducted. The interview questions were derived from the UTAUT aspects. Moreover, all interview scripts segmented into three distinct classifications; age, gender, and occupation. The interview data were analyzed using Nvivo 12. The result shows that tax e-filing system is effective to stimulate the commitment of the participant, not only to use the system regularly and to report their tax return but also to fulfill their tax obligation voluntarily. The e-filing system increases participant productivity because it offers cost reduction and time-saving. Furthermore, it is easy to understand and effortless to use.
