Abstract
Non-oil tax revenue constitutes an integral part of the total revenue of Nigeria. It is expected that the introduction of the Taxpayer Identification Number (TIN) will have a significant effect on total non oil tax revenue since more companies would be captured by the tax net. This paper therefore set out to empirically investigate the effect of TIN on non oil tax revenue through a comparative analysis of pre and post TIN years of 2000 to 2015. Data was collected from Central Bank of Nigeria (CBN) Statistical Bulletin. The study employed both descriptive and pairwise t-test statistical techniques for analyses with total non-oil tax revenue as the dependent variable while CIT, VAT and TET were the independent variables. Findings showed that there has been a significant increase in total non-oil tax revenue with the introduction of TIN. Also, revenue generated from CIT and TET after the implementation of TIN improved significantly. VAT revenue however, did not improve after the implementation of TIN. Recommendations include that the VAT base needs to be enlarged through electronic capture of all VATable persons.
Highlights
Tax reforms are widely accepted as deliberate tax re-engineering by tax policymakers and tax administrators that www.cribfb.com/journal/index.php/ijafrInternational Journal of Accounting & Finance ReviewVol 3, No 1; 2018 ensures compliance by all who should pay fort efficient revenue generation (Harrison, 2002; Azubuike, 2009 and Omesi and Nzor, 2015), through the eradication of fiscal deficits, attraction of higher revenue and improvement of the revenue elasticity or buoyancy of the tax structure (World Bank, 1991)
Literature Review 2.1 Concept of Taxpayer Identification Number (TIN) The Taxpayer Identification Number (TIN) is a platform that harmonizes tax payer identification and registration in Nigeria. It is a major reform put in place by government to reduce the problem of tax administration in Nigeria by capturing taxable persons through an electronic system of tax collection
Variables of interest were Total Non-Oil Revenue, Company Income Tax, Value Added Tax and Tertiary Education Tax on pre TIN and post TIN periods. 3.1.2 Test Statistics Descriptive statistics, precisely mean and standard deviation were employed in comparing the nature of the differences on revenue generation on pre and post TIN periods from identified tax variables and total non-oil revenue
Summary
Tax reforms are widely accepted as deliberate tax re-engineering by tax policymakers and tax administrators that www.cribfb.com/journal/index.php/ijafr. With the introduction of the Tax identification Number (TIN) in 2008, it is expected that the revenue from non-oil tax would increase since it should automatically capture more individuals, enterprises and companies thereby reducing the wide gap between companies registered in Nigeria with the Corporate Affairs Commission (CAC) and those already in the tax net. Literature Review 2.1 Concept of Taxpayer Identification Number (TIN) The Taxpayer Identification Number (TIN) is a platform that harmonizes tax payer identification and registration in Nigeria It is a major reform put in place by government to reduce the problem of tax administration in Nigeria by capturing taxable persons through an electronic system of tax collection. In a bid to further increase states' revenue, the JTB with the collaboration of the federal and state governments introduced the Unique Taxpayer Identification Number (U-TIN) which is again an electronic system of tax identification that assigns unique identification to every taxable person in Nigeria with biometric capabilities.
