EFFECT OF TAXPAYERS’ IDENTIFICATION NUMBER ON REVENUE GENERATION IN LAGOS STATE, NIGERIA

Summary/Abstract: The introduction of the Taxpayers’ Identification Number (TIN) reform in Nigeria was geared towards enhancing tax administration and revenue generation. Therefore, this study examines the effect of taxpayers’ identification number on revenue generation in Lagos state – the commercial nerve centre of Nigeria. Specifically, it investigates the contribution of TIN on internally generated revenue and the influence of TIN on tax compliance in Lagos state. The period under review spans from December 2010 to September 2015, which is divided into the pre-TIN period (December 2010-April 2013) and the post-TIN period (May 2013-September 2015). 300 questionnaires were distributed to randomly selected staffs of the Lagos Inland Revenue Service (LIRS), out of which 221 were properly filled and returned. Regression technique was used to analyse the data sourced through questionnaire. This study finds that TIN has a significant positive relationship with internally generated revenue and it has significantly contributed to tax compliance in Lagos State. The study thus concludes that TIN positively affected internally generated revenue in Lagos state for the period covered by the study. It recommends that government should improve tax extension and education services to make more people, especially at the grassroots level aware of how to pay tax, benefits of paying tax and the need to have a taxpayers’ identification number among others as well as establish forensic tax investigation unit that would curb the excesses of leakages, corruption in tax system and tax defaulters.
