  • Israel S. Akinadewo Obafemi Awolowo University, Ile-Ife, Osun State




The study appraised the most disputed by the taxpayers, of the sources of the Internally Generated Revenue (IGR) in Lagos State, Nigeria, after the tax audit exercise. Primary data through the administration of structured questionnaire on respondents was adopted. The sample size was 301, using Krejcie & Morgan (1970) formula. Personal Income Tax (PIT), Withholding Tax (WHT), Capital Gains Tax (CGT), Stamp Duties (SD), Pools, Betting, Lotteries, Gaming, and Casino Tax (PBLGCT), and Road Tax (RT), were appraised by the tax experts. The study analysed data using descriptive statistical techniques like percentages and tables. The findings revealed that Road Tax (67.8%), Capital Gains Tax (67.5%), Personal Income Tax (65.7%), and Withholding Tax (61.8%) are the most disputed sources of IGR by the taxpayers. The study recommended for the re-evaluation of tax audit process to bridge the gap of disagreement between the taxpayers and the tax auditors/tax authorities for a more efficient tax administration.
