THE IMPACT OF TAXATION ON ECONOMIC GROWTH IN NIGERIA  (1986-2011)
ABSTRACT
The research work will discuss in detail the impact of taxation on Economic growth in Nigeria.  It will also take cognizance of the aims and objectives of taxation and its impact on the economic growth of Nigeria.  It also aimed at identifying problems that inhibit the efficient and effective administration of the Nigeria tax’s system.  In evaluating this, the researcher adopted econometrics by applying Ordinary Least Square (OLS) techniques. It was found out that interest rate has no significant effects on taxation in Nigeria economy for the said period.  Hence, the researcher concludes that interest variation has not really effected investment growth in Nigeria. I recommended that the government should put more emphasize on the aspects of taxation since the main source of development.

INTRODUCTION
Background of the Study
The political, economic and social development of any country depends on the amount of revenue generated for the provision of infrastructure in that given country. However, one means of generating the amount of revenue for providing the needed infrastructure is through a well structured tax system. According to Azubike (2009), tax is a major player in every society of the world. The taxation is an opportunity for government to collect additional revenue needed in discharging its pressing obligations. A taxation offers itself as one of the most effective means of mobilizing a nation’s internal resources and it lends itself to creating an environment conducive to the promotion of economic growth. Nzotta (2007) argues that taxes constitute key sources of revenue to the federation account shared by the federal, state and local governments. This is why Odusola (2006) stated that in Nigeria, the government’s fiscal power is divided into three-tiered tax structure between the federal, state and local governments, each of which has different tax jurisdictions. The system is lopsided and dominated by oil revenue. He further argues that over the past two decades oil revenue has accounted for at least 70% of the revenue, thus indicating that traditional tax revenue has never assumed a strong role in the country’s management of fiscal policy. Instead of transforming the existing revenue base, fiscal management has merely transited from one primary product-based revenue to another, making the economy susceptible to fluctuations of the international market.
However, one of the major functions of any government especially developing countries such as Nigeria is the provision of infrastructural services such as electricity, pipe-borne water, hospitals, schools, good roads and as well as ensure a rise in per capita income, poverty alleviation to mention a few.
For these services to be adequately provided, government should have enough revenue to finance them.  The task of financing these enormous responsibilities is one of the major problems facing the government.  Based on the limited resources of government, there is need to carry the citizens (governed) along hence the imposition of tax on all taxable individuals and companies to augment government financial position.  To this end, government have always enacted various tax laws and reformed existing ones to stand the taste of time.  They include:  Income Tax Management Act (ITMA), Companies Income Tax Decree (CIID), Joint Tax Board (JIB) etc.
All these are aimed at ensuring adherence to tax payment and discouraging tax evasion and avoidance.  For the purpose of this study, the researcher would be concerned with the impact of taxation as an aid to the economic development of Enugu State (Nigeria).
Statement of the Problem
The first need of any modern government is to generate enough revenue which is indeed “the breath of its nostril”.  Thus taxation is by far the most significant source of revenue for the government.  Nigerians regard payment of tax as a means whereby government raises revenue on herself at the expense of their sweat.
It is good to note that no tax succeeds without the taxpayer’s co-operation.  Here, we can ask some thought-provoking questions such as: what makes taxation such a difficult issue?  Why do people feel cheated when it comes to tax?  Is government making judicious use of taxpayer’s money?  In view of these questions above, this study is going to be carried out to offer solution to them.
We shall also look at the following issues and offer recommendations.
1.    Problems affecting the successful operation of tax system in     Nigeria.
2.    How to determine the Assessable income.
3.    Process of tax administration in Nigeria.
1.3    Objective of the Study:
The general objective of the study is to assess the contribution of taxes towards the growth of the Nigeria Economy.
However, the specific objective of the study includes:
1.    The evaluate the nature of relationship that exist between taxation and economic growth in Nigeria.
2.    To determine the extent government has been using revenue generated from tax.
3.    To examine how tax rate affects the rate of investment in the economy.
5.    To know general desirability of firms to invest as a result of tax incentive measures.
Generally, the work is done to find out if tax constitutes the bulk of government revenue and to erase the erroneous that it is an exploitation by government for their selfish interest.
1.4    Research questions
What the nature of relationship that exist between taxation and economic growth.
Do you think that government having using revenue generated from tax for economic growth.
Do tax rate affects the rate of investment in the economy.
1.5    Formulation of Hypothesis:
To enable the researcher test if there exist any correlation between revenue generated from tax and its impact on Nigeria  economy, some statistical  model will be used based on the response from the secondary data obtains from Central Bank of Nigeria annual statistical bulletin.
The Null Hypothesis (Ho):  Revenue generated from tax does not make
any impact on the economic development of Enugu State
The Alternative Hypothesis (HA):  Revenue generated from tax has a
positive impact on the economic development of Enugu State.
   Assumptions of the Study
The researcher in carrying out this study will make the following assumptions:
1.    That the data that will be used are true and fair figures of taxes actually collected by the Federal Government in each year of assessment.
2.    That the data will be authentic and can be relied on for further research work on the topic.
3.    That the data is going to form the basis of the research work.
1.4    Significance of the Study:
One of the most frequently discussed issues in Nigeria is how to solve the economic hardship in the country and how to create an industrial base that can be guarantee self sustaining economic development.  Also one wonders why a country which is richly endowed with the necessary human and material resources and which the people pay tax has been turned a heavily indebted country.
The study will afford us the opportunity to know the roles taxation play in the Nigeria economy such roles includes:
1.    Taxation is a major source of revenue to the government.
2.    Revenue generated from tax enables government performs its functions effectively.
3.    Taxation acts as an instrument of fiscal policy.
4.    The impact of tax on small business in the state.
5.    The study will in addition reveal if there are other better sources of government funding.
1.6    Scope of the Study:
The scope of this study covers critical examinations on the impact of taxation on economic development.  It will also analyze other related issues such as structure and administrative machinery of tax in Nigeria and their associated problems.  The essence of this digression is to possibly find out the obstacles if any, that hinder the effective collection and administration of tax in Nigeria.
   Limitation of the Study:
It can be seen from all indications that a research such as this cannot be carried out in one semester.  There are constraints that limit the work of the researcher.  Among these are:
-    Inadequate Time:  The time available is very limited, as a result of this, the researcher is restricted to some places for interviews and questioning during the collection of data.
-    Insufficient Fund:  The funds available to the researcher is not sufficient to carry out this research work.  As a result of high economic hardship as well as high cost of transportation.
-    The inability of some government officials to disclose certain reliable information which they considered confidential may also limit the study.
-    There is also scarcity of current textbooks on tax because tax laws are constantly changed and so many textbooks are obsolete for this topic.
Finally, the academic workload on the campus is one of the limiting factors on this research work.  Despite all these constraints, the researcher is able to carry out a fair and effective study on this topic.
