This study aims to determine and analyze the determinants of the complexity of tax regulations and the principles of justice regarding taxpayer compliance in Indonesia. The study surveyed 148 individual taxpayers who are entrepreneurs of micro, small, and medium enterprises (MSMEs) using a Google Form. The results show that the complexity of tax regulations has a significant negative effect (–0.253) on taxpayer compliance, and the principles of justice (0.501) have a significant positive effect on taxpayer compliance. An R square shows that independent variables have a 45.5% influence on increasing taxpayer compliance. The degree of the correlation relationship between all independent variables is around 0.674. The results confirm the relationship between the complexity of tax regulations and the principle of justice and their effect on taxpayer compliance. Therefore, to increase taxpayer compliance, the government should put efforts into simplifying and explaining tax regulations. This can help reduce inadvertent errors, increase taxpayer confidence, and reduce the overall cost of complying with regulations. It is important to consider aspects of justice when designing and implementing the tax system. Efforts to increase transparency, reduce injustice, and make taxes applied proportionally can help strengthen taxpayer compliance and support the sustainability of state revenues.
