“…Challenges exist in understanding the differences in making zero-rated supplies and exempt supplies, as both are not subject to output tax (Asmuni et al, 2017;Bidin et al, 2014a;Bidin et al, 2014b;Hartley, 2019;Keen and Lockwood, 2010;Marimuthu and Bidin, 2016;Zhou et al, 2013). Moreover, challenges could arise in the form of compliance efforts towards the new regulation (Troilo et al, 2017). A study by Bidin et al (2014a) reported vital areas that tax agents perceived as challenges in GST implementation, which included, among others, lack of GST knowledge, documentation burden, the need to upgrade computer systems, tax refunds, the need to enhance the accounting system, clarity on taxability, understanding GST law, tax authority, co-operation, input tax credit, exempted goods and services, period of time to lodge the tax return and zero-rated goods and services.…”
