Introduction A tax dispute is a dispute that arises due to differences in understanding of the rights and obligations in implementing tax laws and regulations between the taxpayer and the tax authorities, which can be resolved in the appeal process at the Tax Court. The practice of tax disputes shows the government's performance in upholding the principle of justice, thus giving rise to taxation trust in the broader community (Siahaan, 2012). However, based on the results of the appeal dispute decision in the Indonesian tax court (see Table 1), the Directorate General of Taxes' win rate over tax disputes is relatively low. Almost every year, the percentage of tax authorities losing is higher than that of tax wins. ___________________________ * Paper info: Revised: July 17, 2022 Accepted: September 30, 2022 * Corresponding author: Mega Nurmala Sari E-mail: mg.nurmalasari@com dan rqibthiyyah1@gmail.com Affiliation: Faculty of Economics and Business, Universitas Indonesia, Indonesia
