Abstract:

This study evaluated the mandatory adoption of Taxpayers Identification Number (TIN) on tax revenues and the growth of the economy in Nigeria over 1995 – 2020 period. This was conducted to see if the intended purpose of TIN which is to boost revenue generation reflected in the increment of revenue and economic growth during the specified timeframe. The data were sourced from World Bank and Federal Inland Revenue Service (FIRS) reports. The analysis was conducted using Ordinary Least Square (OLS) Regression to see whether or not the intended purposes were achieved. The outcome of the study disclosed that one of the purposes of TIN was achieved. It is recommended that the TIN reform should be revised to ensure that it covers every single taxpayer in the nation because it is evident that a wide tax gap is still prevalent in Nigeria. Digitization of tax remittance such as e-payment facilities should also be worked upon to easily capture persons for complete tax assessment.
