1.1 Introduction
Tax administration is defined as the set of institutional frameworks, processes, and practices through which government tax authorities assess, collect, monitor, and enforce tax compliance in order to generate public revenue for development purposes (OECD, 2021). In modern public finance, effective tax administration is regarded as a critical instrument for ensuring fiscal sustainability, reducing dependence on external borrowing, and strengthening government capacity to deliver essential services (Bird & Zolt, 2015). In Enugu State, Nigeria, the State Board of Internal Revenue is responsible for managing internally generated revenue through the collection of personal income tax, levies, and other statutory payments. The efficiency of this administration directly influences the level of revenue available for infrastructural development, education, healthcare, and other public goods. When tax administration is weak, revenue leakage, tax evasion, and inefficiencies tend to increase, thereby reducing the overall fiscal capacity of the state government (Fjeldstad & Moore, 2019).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.
1.2 Background of Study
Taxation is widely recognized as a fundamental instrument of public finance used by governments to generate revenue for the provision of essential services, infrastructure development, and economic stability. According to Bird and Zolt (2015), effective tax systems are not only designed to raise revenue but also to promote equity, efficiency, and administrative simplicity. They asserted that the strength of tax administration significantly influences the ability of governments to mobilize domestic revenue, especially in developing economies where reliance on external borrowing and aid is high. In many African countries, including Nigeria, the challenge is not only about tax policy design but also about the effectiveness of tax administration structures responsible for implementation.
According to the Organisation for Economic Co-operation and Development (OECD, 2021), tax administration involves the full range of activities required to implement tax laws, including taxpayer registration, assessment, collection, audit, enforcement, and dispute resolution. The OECD reported that countries with modernized tax administrations, particularly those that have adopted digital systems, tend to record higher levels of compliance and improved revenue performance. Aguolu (2004) reported that, the Nigerian tax system is characterized by administrative inefficiencies, weak enforcement mechanisms, and widespread tax evasion. He asserted that these challenges significantly reduce the capacity of state governments to generate sufficient internal revenue. In the context of Enugu State, these issues are reflected in persistent revenue shortfalls and overdependence on statutory allocations from the federal government.
According to Fjeldstad and Moore (2019), tax administration in developing countries is often constrained by corruption, lack of transparency, and weak institutional capacity. They contended that when taxpayers perceive the tax system as unfair or corrupt, voluntary compliance declines, leading to reduced revenue generation. In many sub-Saharan African countries, trust between taxpayers and tax authorities remains low, thereby affecting the effectiveness of tax collection systems. In Nigeria, the State Internal Revenue Services, including the Enugu State Board of Internal Revenue, are mandated to administer and collect taxes such as personal income tax, withholding tax, and various levies.
Odusola (2006) stated that, state tax authorities play a critical role in domestic revenue mobilization, especially under Nigeria's federal structure where states depend heavily on internally generated revenue to finance their budgets. He stated that the efficiency of state tax administration determines the financial autonomy and developmental capacity of sub-national governments. Ola (2001), inefficiencies in tax administration such as poor record keeping, inadequate taxpayer education, and weak enforcement contribute significantly to revenue leakages in Nigeria. He affirmed that many taxpayers remain outside the tax net due to ineffective identification systems and lack of comprehensive data management. These challenges are particularly evident in rapidly urbanizing states like Enugu, where economic activities are expanding but tax capture remains limited.
Tanzi and Zee (2000), technological innovation in tax administration, including automation and digitalization of tax processes, enhances transparency and reduces opportunities for corruption. They contended that countries that invest in modern tax administration systems experience improved compliance rates and higher revenue yields. In Enugu State, the State Board of Internal Revenue is responsible for ensuring effective tax collection and compliance enforcement. However, despite various reforms, issues such as inadequate manpower, limited technological adoption, and weak monitoring systems continue to affect revenue generation performance. According to Appah and Oyandonghan (2011), inefficiencies in tax administration in Nigerian states significantly hinder the mobilization of internal revenue, thereby affecting overall economic development. This study is set against the backdrop of the need to evaluate how tax administration affects revenue generation in Enugu State.
1.3 Statement of Problems
Investigation revealed that there is inefficiency in taxpayer registration and identification, which results in a large informal sector remaining outside the tax net (OECD, 2021). On the other hand, poor accountability mechanisms and limited use of digital tax administration tools further contribute to revenue leakages, thereby reducing internally generated revenue (Bird & Zolt, 2015).
Furthermore, issues of corruption and lack of transparency in tax collection processes have continued to undermine public trust in the tax system (Fjeldstad & Moore, 2019). In addition, inadequate training and motivation of tax personnel affect service delivery and operational efficiency. Many tax officers operate without modern tools and updated databases, which reduces the accuracy of assessments and weakens enforcement procedures. It is against this backdrop that this study seeks to examine the effect of tax administration on revenue generation in Enugu State.
1.4 Aim and Objectives of Study
The aim of this study is to assess the effect of tax administration on revenue generation in Enugu State. The specific objectives of the study are to:
- Examine the effect of taxpayer registration processes on revenue generation in Enugu State.
- Evaluate the impact of tax assessment procedures on internally generated revenue.
- Determine the effect of tax collection methods on revenue performance in Enugu State.
- Assess the influence of tax enforcement strategies on tax compliance.
- Investigate the role of digital tax administration systems on revenue generation efficiency.
1.5 Research Questions
The study is guided by the following research questions:
- How does taxpayer registration affect revenue generation in Enugu State?
- What is the impact of tax assessment procedures on internally generated revenue?
- How do tax collection methods influence revenue performance in Enugu State?
- In what way does tax enforcement affect tax compliance among taxpayers?
- How does digital tax administration influence revenue generation efficiency in Enugu State?

- H1: Digital tax administration systems significantly improve revenue generation efficiency in Enugu State.
1.7 Significance of Study
It is believed that at the completion of the study, policymakers in Enugu State will use the findings to improve tax administration policies and strengthen revenue generation systems. Also, the State Board of Internal Revenue will enhance its operational efficiency through improved tax collection and enforcement strategies.
Furthermore, taxpayers in Enugu State will benefit from improved transparency and accountability in tax administration processes. In addition, the Enugu State Government will strengthen its internally generated revenue base and reduce dependence on federal allocations.
Lastly, researchers will use the findings as a reference for further academic studies on tax administration and public finance.
1.8 Scope and Limitations of the Study
