摘要:Tax revenues constitute a major source of income for governments in most countries. However, the increasing concern on the extent of tax evasion has induced a lot of studies in different countries on the amount of unreported incomes and factors accounting for this phenomenon especially in emerging economies. To analyse this topic, Nigeria has been chosen as a reference point. In order to enhance objectivity, an empirical study has been carried out through a structured survey directed at tax professionals. This information was collected in order to explain the determinants of tax evasion. The results show that tax evasion in Nigeria is largely influenced by complexity in the tax structure, perceived financial and economic benefits associated with tax evasion, and lack of trust in governance over financial resource utilization. This outcome suggest that there should be adequate implementation of appropriate recommendations made in this study towards enhancing a better tax policy and improved tax administration in the country. The study also provides information for future research that might contribute to establish the most adequate mechanisms for taxation.
