EVALUATION OF TAXATION AS A TOOL FOR ECONOMIC GROWTH AND DEVELOPMENT IN NIGERIA FROM 2006-2015

CHAPTER ONE

INTRODUCTION

1.1 Background of the Study

Taxation is one of the most important sources of government revenue and a major instrument used for economic growth and development in every nation. Governments rely on taxes for financing public expenditure, providing social amenities, maintaining infrastructure, promoting industrialization, and ensuring economic stability. In developing economies such as Nigeria, taxation plays a significant role in mobilizing resources for national development and reducing excessive dependence on external borrowing and oil revenue (Appah, 2016).

Economic growth refers to the increase in the productive capacity of an economy over time, usually measured by growth in Gross Domestic Product (GDP), while economic development involves improvement in living standards, reduction in poverty, employment generation, infrastructural development, and enhancement of citizens’ welfare. Taxation contributes to these objectives by providing government with funds required for developmental projects and public services (Todaro and Smith, 2015).

The Nigerian economy has historically depended heavily on crude oil revenue as the major source of government income. However, fluctuations in global oil prices, economic recessions, and declining oil production exposed the weaknesses associated with overdependence on petroleum revenue. Consequently, the government increasingly turned attention toward taxation as a sustainable source of revenue generation capable of supporting economic growth and development (Ariyo, 2018).

Taxation serves several economic functions beyond revenue generation. It is used as an instrument for income redistribution, inflation control, regulation of consumption patterns, protection of local industries, and promotion of investment activities. Governments may use taxation policies to encourage production in strategic sectors and discourage consumption of harmful goods through higher tax rates (Musgrave and Musgrave, 2017).

In Nigeria, the tax system consists of direct and indirect taxes administered by different government agencies. Direct taxes include personal income tax, company income tax, petroleum profit tax, and capital gains tax, while indirect taxes include Value Added Tax (VAT), customs duties, and excise duties. These taxes are administered mainly by the Federal Inland Revenue Service and state revenue agencies (FIRS, 2021).

The Nigerian government introduced several tax reforms between 2006 and 2015 aimed at improving tax administration, increasing revenue generation, and enhancing economic development. These reforms included modernization of tax administration systems, introduction of electronic tax payment platforms, expansion of VAT coverage, strengthening of tax enforcement mechanisms, and taxpayer education programs (Ariyo, 2018).

Tax revenue is essential for financing infrastructural development projects such as roads, electricity supply, healthcare facilities, schools, water supply, and transportation systems. Adequate infrastructure contributes significantly to economic growth by improving productivity, reducing production costs, and encouraging investment activities. Consequently, effective taxation systems support economic development through increased government expenditure on public services (Appah, 2016).

The period between 2006 and 2015 witnessed significant economic changes in Nigeria including banking reforms, economic expansion, fluctuations in oil prices, inflationary pressures, and government efforts toward economic diversification. During this period, taxation became increasingly important as government sought alternative sources of revenue to support economic growth and development (CBN, 2016).

Despite the importance of taxation, Nigeria continues to face several challenges associated with tax administration and revenue generation. These challenges include tax evasion, tax avoidance, corruption, weak enforcement mechanisms, inadequate tax education, poor record keeping, and inefficiencies within tax administration agencies. Such challenges reduce government revenue and negatively affect economic development efforts (Appah, 2016).

Tax evasion and avoidance remain major problems affecting revenue generation in Nigeria. Many individuals and organizations deliberately fail to declare accurate income or pay taxes as required by law. These practices reduce government revenue available for developmental projects and public services. Weak tax administration systems and corruption further worsen the situation (Olowe, 2017).

The effectiveness of taxation as a tool for economic growth depends significantly on proper utilization of tax revenue. Citizens expect government to utilize tax proceeds for developmental projects capable of improving living standards and promoting economic progress. Mismanagement of public funds and corruption may therefore reduce public confidence in the tax system and discourage voluntary compliance (Musgrave and Musgrave, 2017).

Taxation also affects private sector performance and investment activities within the economy. Moderate and efficient tax systems encourage business growth, entrepreneurship, and foreign investment, while excessive tax burdens may discourage investment and reduce productivity. Governments must therefore balance revenue generation objectives with the need to promote economic activities and industrial development (Pandey, 2015).

The manufacturing, agricultural, banking, and telecommunications sectors contribute significantly to tax revenue generation in Nigeria. Through company income tax, VAT, customs duties, and other levies, businesses provide substantial revenue for government operations and development projects. Effective tax administration within these sectors therefore contributes positively to economic growth (Ariyo, 2018).

The Federal Inland Revenue Service has implemented several reforms aimed at improving tax compliance and revenue collection efficiency. These reforms include digitalization of tax administration, automation of tax payment systems, strengthening of audit and enforcement mechanisms, and increased taxpayer sensitization programs (FIRS, 2021).

Economic growth and development require substantial financial resources for implementation of government policies and developmental projects. Taxation provides government with stable and sustainable revenue capable of financing infrastructure, education, healthcare, security, and social welfare programs necessary for national development (Todaro and Smith, 2015).

Furthermore, taxation promotes redistribution of income within society. Progressive taxation systems ensure that individuals and organizations with higher income contribute more toward government revenue, thereby reducing income inequality and supporting social welfare programs. Taxation therefore contributes not only to economic growth but also to social and economic development (Musgrave and Musgrave, 2017).

Several empirical studies have examined the relationship between taxation and economic growth in developing economies. While some studies indicate that effective taxation contributes positively to economic growth through increased government expenditure on infrastructure and public services, others reveal that excessive taxation may discourage investment and reduce economic productivity (Appah, 2016).

In recent years, the Nigerian government intensified efforts toward increasing non-oil revenue through improved taxation policies due to declining oil revenue and economic uncertainties. This shift highlights the growing importance of taxation in achieving sustainable economic growth and development within the country (CBN, 2016).

The success of taxation as a tool for economic growth depends largely on efficient tax administration, transparency in utilization of tax revenue, public accountability, and effective implementation of fiscal policies. Governments must therefore strengthen tax institutions and ensure proper utilization of tax proceeds for developmental purposes (Olowe, 2017).

In view of the importance of taxation in national development and the increasing emphasis on non-oil revenue generation, this study seeks to evaluate taxation as a tool for economic growth and development in Nigeria covering the period from 2006 to 2015.

1.2 Statement of the Problem

Taxation is expected to serve as a major source of government revenue and an effective instrument for promoting economic growth and development. Despite the increase in tax revenue generation in Nigeria, the country still faces significant developmental challenges such as inadequate infrastructure, unemployment, poverty, poor healthcare services, and low industrial productivity.

The Nigerian tax system also experiences several problems including tax evasion, corruption, weak enforcement mechanisms, poor administration, and inadequate public accountability. These challenges reduce government revenue and limit the ability of taxation to achieve economic development objectives.

Furthermore, many citizens and businesses complain about multiple taxation and poor utilization of tax proceeds by government authorities. Questions therefore arise regarding the effectiveness of taxation as a tool for economic growth and development in Nigeria.

It is against this background that this study seeks to evaluate taxation as a tool for economic growth and development in Nigeria from 2006 to 2015.

CHAPTER TWO

REVIEW OF RELATED LITERATURE

2.1 Conceptual Framework

The conceptual framework of this study focuses on taxation as an instrument for economic growth and development in Nigeria. Taxation is recognized globally as one of the major sources of government revenue and a significant tool for fiscal policy implementation. Governments utilize taxation to generate funds necessary for the provision of public goods and services, redistribution of income, stabilization of the economy, and stimulation of economic activities (Musgrave and Musgrave, 2017).

Economic growth and development remain major objectives of government policies in both developed and developing countries. Economic growth refers to increase in national output and income over time, while economic development involves broader improvements in living standards, employment opportunities, infrastructural development, reduction in poverty, and enhancement of citizens’ welfare. Taxation contributes to these objectives by providing government with the financial resources necessary for implementing developmental projects and economic policies (Todaro and Smith, 2015).

In Nigeria, taxation has become increasingly important due to fluctuations in oil revenue and the need for economic diversification. The Nigerian government depends on tax revenue for financing public expenditure, maintaining infrastructure, and promoting economic development. Tax revenue is generated through various forms of taxes including company income tax, petroleum profit tax, customs duties, excise duties, and Value Added Tax (VAT) (Appah, 2016).

The conceptual framework of this study therefore examines major concepts relating to taxation, tax administration, economic growth, economic development, government revenue generation, infrastructural development, and fiscal policy. The framework also explains how effective taxation systems contribute to economic growth and national development in Nigeria.

2.1.1 Meaning of Taxation

Taxation refers to compulsory levies imposed by government on individuals, businesses, goods, services, and properties for the purpose of generating revenue and regulating economic activities. According to Appah (2016), taxation is a fiscal policy instrument used by government to finance public expenditure and influence economic behavior within society.

Taxes are compulsory because payment is enforced by law and failure to comply may result in penalties or legal sanctions. Taxation differs from voluntary contributions because taxpayers are legally required to pay taxes according to established laws and regulations (Musgrave and Musgrave, 2017).

Taxation performs several important functions within an economy. First, it generates revenue for government operations and developmental projects. Second, taxation promotes redistribution of income through progressive tax systems. Third, taxation serves as a tool for economic stabilization by controlling inflation, encouraging investment, and regulating consumption patterns (Ariyo, 2018).

The Nigerian tax system consists of direct and indirect taxes. Direct taxes are imposed directly on income and profits of individuals and organizations, while indirect taxes are imposed on goods and services consumed within the economy. Major taxes in Nigeria include company income tax, personal income tax, petroleum profit tax, customs duties, excise duties, and Value Added Tax (VAT) (FIRS, 2021).

Effective taxation systems contribute significantly to economic growth because they provide government with stable and sustainable revenue for financing developmental projects and public services. However, poor tax administration, corruption, and tax evasion may reduce the effectiveness of taxation within an economy (Olowe, 2017).

2.1.2 Objectives of Taxation

One major objective of taxation is revenue generation. Governments require substantial financial resources for financing public expenditure such as roads, schools, healthcare facilities, electricity supply, transportation systems, and security services. Tax revenue therefore supports implementation of government policies and developmental programs (Appah, 2016).

Another objective of taxation is redistribution of income and wealth within society. Progressive tax systems ensure that individuals and organizations with higher income contribute more taxes compared to low-income earners. Government may utilize tax revenue for social welfare programs aimed at reducing poverty and improving living standards (Musgrave and Musgrave, 2017).

Taxation also serves as an instrument for economic stabilization and regulation. Governments use tax policies to control inflation, encourage savings and investment, regulate consumption patterns, and protect local industries. Higher taxes may discourage consumption of harmful products, while tax incentives may stimulate investment in strategic sectors of the economy (Todaro and Smith, 2015).

Another important objective of taxation is promotion of economic growth and development. Government utilizes tax revenue for financing infrastructural development projects capable of improving productivity and encouraging business activities. Adequate infrastructure contributes positively to industrial growth, employment generation, and national development (Ariyo, 2018).

Taxation further promotes accountability and good governance. Citizens who pay taxes expect government to utilize public funds responsibly and provide quality public services. Effective tax systems therefore encourage transparency and accountability within public administration (Appah, 2016).

2.1.3 Types of Taxes in Nigeria

The Nigerian tax system consists of various forms of taxes administered by federal, state, and local government authorities. These taxes are classified broadly into direct and indirect taxes (FIRS, 2021).

Direct Taxes

Direct taxes are imposed directly on income, profits, and wealth of individuals and organizations. Examples include personal income tax, company income tax, petroleum profit tax, and capital gains tax. These taxes are usually paid directly by taxpayers to government authorities (Appah, 2016).

Personal Income Tax

Personal income tax is imposed on earnings of individuals, employees, and self-employed persons. State Boards of Internal Revenue are responsible for administering personal income tax within Nigeria (Ariyo, 2018).

Company Income Tax

Company income tax is imposed on profits earned by registered companies operating in Nigeria. The tax contributes significantly to government revenue generation and economic development (FIRS, 2021).

Petroleum Profit Tax

Petroleum profit tax is imposed on profits generated by companies engaged in petroleum exploration and production activities. Due to Nigeria’s dependence on oil revenue, petroleum profit tax remains one of the major sources of government income (Olowe, 2017).

Indirect Taxes

Indirect taxes are imposed on goods and services rather than directly on income or profits. Examples include Value Added Tax (VAT), customs duties, and excise duties (Appah, 2016).

Value Added Tax (VAT)

VAT is a consumption tax imposed on value added to goods and services at different stages of production and distribution. VAT constitutes one of the major sources of non-oil revenue in Nigeria (FIRS, 2021).

Customs and Excise Duties

Customs duties are taxes imposed on imported goods entering the country, while excise duties are imposed on locally manufactured goods. These taxes are used to generate revenue and protect local industries from excessive foreign competition (Ariyo, 2018).

2.1.4 Taxation and Economic Growth

Economic growth refers to increase in the productive capacity and output of an economy over time. It is commonly measured using Gross Domestic Product (GDP), national income, and productivity indicators. Taxation contributes to economic growth through revenue generation, infrastructural development, and implementation of fiscal policies (Todaro and Smith, 2015).

Government utilizes tax revenue for financing infrastructure such as roads, electricity, transportation systems, communication networks, and educational institutions. These infrastructures improve productivity, reduce production costs, and encourage investment activities within the economy (Appah, 2016).

Taxation also influences economic growth through fiscal policy measures. Government may reduce tax rates in order to stimulate investment and increase economic activities during economic recessions. Conversely, tax increases may be used to control inflation and excessive consumption within the economy (Musgrave and Musgrave, 2017).

However, excessive taxation may negatively affect economic growth by discouraging investment and reducing business profitability. High tax burdens may increase production costs and reduce incentives for entrepreneurship and industrial expansion. Governments must therefore maintain balanced tax policies capable of supporting both revenue generation and economic growth (Pandey, 2015).

In Nigeria, the relationship between taxation and economic growth has become increasingly important due to efforts toward economic diversification and reduction of dependence on oil revenue. Effective taxation systems are expected to support sustainable economic growth and development within the country (Ariyo, 2018).

2.1.5 Taxation and Economic Development

Economic development involves improvement in living standards, reduction in poverty, employment generation, healthcare delivery, educational advancement, and infrastructural development. Taxation contributes significantly to economic development by providing financial resources necessary for implementation of social and economic programs (Todaro and Smith, 2015).

Tax revenue enables government to provide social amenities such as hospitals, schools, water supply, and electricity necessary for improving quality of life within society. These public services contribute positively to human capital development and economic progress (Appah, 2016).

Taxation also promotes employment generation through government expenditure on developmental projects and public sector activities. Increased government investment in infrastructure and industrial development stimulates economic activities and creates employment opportunities for citizens (Olowe, 2017).

Redistribution of income through taxation contributes to social and economic development by reducing income inequality and promoting social welfare. Progressive taxation systems ensure equitable distribution of tax burdens and support government programs aimed at poverty alleviation (Musgrave and Musgrave, 2017).

Despite these benefits, poor utilization of tax revenue and corruption may reduce the effectiveness of taxation in promoting economic development. Mismanagement of public funds may prevent tax revenue from translating into meaningful developmental outcomes within society (Appah, 2016).

2.1.6 Tax Administration in Nigeria

Tax administration refers to the process of assessing, collecting, managing, and enforcing tax payments within an economy. Effective tax administration is essential for improving compliance, reducing tax evasion, and increasing government revenue generation (FIRS, 2021).

In Nigeria, tax administration is carried out by various government agencies including the Federal Inland Revenue Service, State Boards of Internal Revenue, and Local Government Revenue Committees. These agencies are responsible for assessment, collection, and enforcement of taxes within their respective jurisdictions (Appah, 2016).

The Nigerian government implemented several tax reforms between 2006 and 2015 aimed at improving tax administration efficiency. These reforms included automation of tax systems, electronic tax payment platforms, taxpayer education programs, and strengthening of audit and enforcement mechanisms (Ariyo, 2018).

Despite these reforms, tax administration in Nigeria continues to face several challenges including corruption, inadequate manpower, poor record keeping, tax evasion, and weak enforcement mechanisms. These challenges reduce government revenue and negatively affect economic development efforts (Olowe, 2017).

Effective tax administration contributes positively to economic growth because it increases revenue generation, improves public confidence in the tax system, and promotes accountability in public finance management (FIRS, 2021).

2.2 Theoretical Framework

The theoretical framework of this study is based on theories explaining taxation and economic development. These theories provide explanations regarding how taxation influences government revenue generation, economic growth, and national development. The study adopts the following theories:

1. Benefit Theory of Taxation
2. Ability-to-Pay Theory
3. Keynesian Theory of Taxation

2.2.1 Benefit Theory of Taxation

The Benefit Theory of Taxation states that individuals and organizations should pay taxes according to the benefits they receive from government services and public expenditure. According to this theory, taxes represent payments for public goods and services provided by government such as roads, healthcare, electricity, education, and security (Musgrave and Musgrave, 2017).

The theory assumes that taxpayers derive benefits from government activities and should therefore contribute toward financing public expenditure. Businesses and individuals benefiting more from public services are expected to contribute more taxes to government revenue (Appah, 2016).

The relevance of this theory to the study lies in its explanation of how taxation supports economic growth and development through government provision of infrastructure and public services. Tax revenue generated by government is expected to improve living standards and promote economic activities within society.

2.2.2 Ability-to-Pay Theory

The Ability-to-Pay Theory states that taxes should be imposed according to the financial capacity of taxpayers. Individuals and organizations with higher income or wealth should contribute more taxes compared to those with lower income levels (Musgrave and Musgrave, 2017).

The theory emphasizes fairness and equity in taxation systems. Progressive taxation ensures equitable distribution of tax burdens and supports redistribution of income within society. Governments may use taxation to reduce economic inequality and finance social welfare programs (Todaro and Smith, 2015).

This theory is relevant to the study because equitable taxation contributes positively to economic development and social welfare. Tax systems capable of balancing revenue generation with fairness and economic growth are more likely to promote sustainable national development (Appah, 2016).

2.2.3 Keynesian Theory of Taxation

The Keynesian Theory, developed by John Maynard Keynes, explains the role of government fiscal policies including taxation in regulating economic activities and promoting economic growth. According to Keynesian theory, government may use taxation and public expenditure to influence aggregate demand, employment, and economic stability (Keynes, 1936).

During economic recessions, government may reduce taxes in order to stimulate consumption, investment, and economic activities. Conversely, taxes may be increased during inflationary periods to reduce excessive demand within the economy (Pandey, 2015).

The theory is relevant to this study because it explains how taxation serves as a fiscal policy instrument for promoting economic growth and development in Nigeria. Government utilizes tax revenue for financing public expenditure and implementing economic development programs capable of improving national productivity and welfare.
