Investigating the compliance behavior of GST taxpayers: An extension to theory of planned behavior

The government around the globe are striving to improve their public finance to meet their public expenditures and for sustainable development of their economies. However, the capability of the governments to generate adequate revenue is limited and refrained by numerous factors. The non-compliance behavior of GST taxpayers is one of the major factors attributed to this phenomenon. Therefore, this paper endeavors to frame and validate a comprehensive instrumental scale with the application of the extended Theory of Planned Behavior (TPB) for analyzing the determinants of compliance behavior of GST taxpayers in India. The current study has adopted the quantitative design through exploratory and confirmatory studies by incorporating qualitative semi-structured interviews with 100 GST consultants to validate the instrumental scale. The study has collected a random sample of 339 GST taxpayers using snowball random sampling. Meanwhile, the study has employed the Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) for analyzing the collected data. The result affirms six major factors in determining the compliance behavior of GST taxpayers explaining 65.166% of the total variance. The findings have instituted perceived complexity, trust and moral obligation in addition to three major constructs of TPB theory namely attitude behavior, subjective norms and perceived behavioral control of the GST taxpayers. The results explicate that the compliance behavior of GST taxpayers is a dynamic and multifaceted phenomenon and it is critical for GST authorities to comprehend the compliance behavior of GST taxpayers. The result explicates that there is a need to simplify and rationalize the GST system in India to increase voluntary compliance of taxpayers. The results also endorse for building trust between GST taxpayers, GST authorities and the state. This study may act as a baseline for formulating policies and strategies on GST in India. There is hardly any national and international study that has applied the extended theory of planned behavior for studying the antecedents of compliance behavior of GST taxpayers.
