LITERATURE REVIEW
Conceptual Review
Taxation
Taxation is a fundamental mechanism through which governments generate revenue to fund public services, infrastructure, and various government functions. It typically involves the imposition of charges on individuals, businesses, and entities, to finance state activities. According to Ajala and Afolabi (2021), taxation is defined as a legal process by which governments levy charges on citizens and corporations to support their activities. This system is pivotal in ensuring that the government has the resources to address national needs, ranging from infrastructure development to public welfare programs.
However, while taxation is essential for government revenue, its ability to foster economic growth is influenced by the efficiency of its design and implementation. Nwachukwu et al. (2022) argue that poorly designed tax systems or inefficient administration can hinder economic development. Tax policies, such as high tax rates or the complexity of tax codes, may discourage investment or lead to economic distortions. Furthermore, tax evasion, whether due to weak enforcement or public resistance, can significantly undermine the system’s effectiveness.
The relevance of taxation to this study cannot be overstated. Taxation serves as the primary tool through which governments in Nigeria, and globally, generate the revenue required to fund critical sectors such as education, healthcare, and infrastructure. According to Ogbonna and Appah (2012), an efficient tax system can enable sustainable economic development by ensuring that adequate resources are allocated to these sectors. This study will examine how Nigeria’s tax system contributes to the country’s economic growth by focusing on its role in generating government revenue.
Despite its significance, taxation faces certain limitations in Nigeria. The system’s effectiveness is often compromised by factors such as corruption, weak tax compliance, and inadequate administrative capacity. As Azubike (2023) notes, the lack of effective enforcement and the informal nature of many economic activities in Nigeria create significant challenges for tax authorities. These limitations highlight the need for reforms to improve the tax system’s efficiency and its contribution to economic growth.
Economic Growth
Economic growth refers to the increase in the production of goods and services within an economy over a specified period. It is typically measured by the rise in a country’s gross domestic product (GDP), reflecting the overall expansion of economic activity. Mankiw and Weinzierl (2023) define economic growth as the increase in a nation’s output, which is often used as an indicator of progress and prosperity. Economic growth is a key objective for policymakers as it directly influences job creation, income levels, and the overall standard of living in a country.
While economic growth is a critical measure of a nation’s prosperity, it has certain limitations. One major critique, as highlighted by Joseph and Chukwuemeka (2018), is that economic growth metrics often fail to address issues related to income inequality and the equitable distribution of wealth. Rapid growth can occur while large portions of the population remain impoverished, and the benefits of growth may not be evenly distributed. Additionally, economic growth may overlook environmental sustainability. As observed by Ogbonna and Appah (2012), unchecked growth could lead to environmental degradation, such as pollution and resource depletion, which may undermine long-term prosperity.
Understanding economic growth is essential in evaluating how tax revenues are utilized to foster sustainable development. Taxation plays a significant role in financing government programs aimed at improving infrastructure, healthcare, and education, all of which contribute to long-term growth. However, as noted by Afolayan and Okonkwo (2019), the quality of growth matters as much as its quantity. Growth driven solely by resource extraction or unsustainable industrial practices may not result in genuine, inclusive prosperity.
The limitations of economic growth as a measure also lie in its failure to capture the social and environmental impacts of taxation. For instance, tax revenue may contribute to economic expansion, but if it is not used in socially beneficial ways or leads to negative environmental outcomes, it may not result in truly sustainable growth. Therefore, while economic growth is an important indicator, it should be complemented by other measures that account for the broader impacts of tax policies.

RESEARCH METHODOLOGY
Introduction
This chapter outlines the research methodology employed in this study to examine the impact of tax reforms on Nigeria’s economic growth, with a particular focus on value-added tax (VAT), corporate income tax (CIT), and other related tax reforms. It details the research design, data analysis techniques, model specification, a priori expectations, and sources of data utilized in the study. The selected methodology aligns with the study’s aim to understand how tax reforms have contributed to Nigeria’s economic growth from 2010 to 2023. This chapter ensures that the research process is transparent, systematic, and rigorous, providing a clear framework for data collection and analysis.
Research Design
The research design adopted for this study is correlational research design, which seeks to explore the relationship between two or more variables without manipulating them. The objective of using this design is to assess the degree and direction of the relationship between tax reforms (such as VAT and CIT) and Nigeria’s economic growth over time. As outlined by Saunders et al. (2019), correlational research allows for the identification of associations between variables, which is crucial when the researcher does not control or manipulate these variables but aims to understand how they interact with each other.
The design was chosen because it provides a systematic way to analyze the impact of tax reforms on economic growth based on existing data. By using this design, the study aims to evaluate the effect of tax reforms on economic performance, such as GDP growth, over the last decade. This approach is particularly suitable when studying variables that are already in place, such as national tax policies and economic indicators, and is consistent with similar research in the field (Ifeoma et al., 2023; Ayano, 2022).

RESULTS AND DISCUSSION

SUMMARY, CONCLUSION AND RECOMMENDATIONS
Summary of Findings
The study on the impact of Value-Added Tax (VAT), Company Income Tax (CIT), and the allocation of tax revenues to key sectors (education, healthcare, and infrastructure) on Nigeria’s economic growth from 2010 to 2023 revealed several crucial insights into the relationship between taxation and economic performance in the country. These findings are summarized below.
Firstly, the relationship between changes in VAT and CIT rates and Nigeria’s GDP growth between 2010 and 2023 was examined. The analysis demonstrated that VAT rates had a statistically significant effect on GDP growth, while CIT rates did not show the same level of influence. This finding is consistent with the existing literature, where VAT, a consumption-based tax, is often seen as more directly linked to economic activity compared to CIT, which primarily affects businesses and corporations. The result suggests that VAT is a more effective tool for economic policy in Nigeria, likely due to the broader base of consumers affected by it, as opposed to CIT, which impacts a smaller proportion of the population—corporate entities. This finding mirrors Afolayan and Okonkwo’s (2019) study, which emphasized the importance of VAT in influencing inflation and government borrowing.
Secondly, the contribution of VAT and CIT revenues to Nigeria’s GDP growth was analyzed. The study found that both VAT and CIT revenues had a significant impact on Nigeria’s economic growth. This aligns with the perspectives of several scholars, including Asaolu et al. (2018), who have noted that tax revenues are critical for financing government expenditure. In turn, this expenditure contributes to the development of infrastructure, healthcare, and education, which are essential for long-term economic growth. The positive contribution of tax revenues reinforces the notion that taxation plays a vital role in the economic development of developing countries like Nigeria, which rely heavily on taxes for funding public services and investments in infrastructure.
However, the study also examined the impact of the allocation of tax revenues to key sectors, including education, healthcare, and infrastructure. The results showed that the allocation of tax revenues to these sectors did not have a statistically significant effect on GDP growth. Although the allocation to education, healthcare, and infrastructure was expected to directly improve economic outcomes by promoting human capital development and infrastructure growth, the study’s findings suggest that other factors may be at play. Despite significant investments in these sectors, challenges such as inefficient resource management, corruption, and ineffective governance may be hindering the expected positive impact on GDP growth. This result aligns with the work of Agwor and Danebari (2020), who pointed out that the inefficiency in public fund management often diminishes the expected benefits from allocations to key sectors.
The finding also suggests that while the government has made efforts to allocate significant portions of tax revenues to sectors like education and healthcare, the outcomes are not fully realized due to systemic issues such as poor infrastructure, inadequate monitoring mechanisms, and lack of accountability in public sector management. As emphasized by Amah (2021) and other scholars, these inefficiencies impede the optimal use of tax revenues, thereby limiting their potential impact on economic growth.
In summary, the findings from this study reveal that while VAT and CIT revenues significantly contribute to Nigeria’s economic growth, the allocation of these revenues to critical sectors like education, healthcare, and infrastructure does not produce the expected positive impact. This suggests the need for improved management of public resources and enhanced efficiency in the allocation of funds to achieve the desired economic outcomes. Moreover, the study calls for a reevaluation of tax policies and public spending strategies to ensure that the benefits of taxation are more effectively realized in fostering economic development.
Conclusion
The results from the hypotheses tested provide significant insights into the relationship between taxation and Nigeria’s economic growth between 2010 and 2023. The study concluded that while changes in VAT rates have a significant impact on Nigeria’s GDP growth, CIT rates do not show the same level of influence. This suggests that VAT, as a consumption-based tax, plays a more direct role in driving economic activity compared to CIT, which primarily affects businesses.
Further, the study confirmed that VAT and CIT revenues significantly contribute to Nigeria’s GDP growth, underscoring the essential role of taxation in financing government expenditure and fostering economic development. However, despite the substantial allocation of tax revenues to sectors like education, healthcare, and infrastructure, the study found that such allocations did not yield a statistically significant impact on GDP growth. This points to underlying inefficiencies in the management and utilization of public resources, which hinder the expected benefits from investments in these critical sectors.
In conclusion, the study highlights the importance of optimizing tax policies and improving public resource management to maximize the positive effects of taxation on Nigeria’s economic growth. Enhanced accountability, governance, and strategic investment in key sectors are crucial to unlocking the full potential of tax revenues for sustainable economic development.
Recommendations
Based on the findings of the study, the following recommendations are made:
- Optimize VAT Implementation: Since changes in VAT rates significantly impact GDP growth, the Nigerian government should focus on optimizing VAT implementation. This could involve broadening the VAT base, reducing exemptions, and improving compliance among businesses to enhance revenue generation and economic activity.
- Enhance CIT Rate Structure: Although changes in Corporate Income Tax (CIT) rates did not show a significant impact on GDP growth, adjustments in the CIT structure could encourage greater business investment. The government could consider providing tax incentives to businesses that contribute to job creation and economic expansion, particularly in sectors with high growth potential.
- Strengthen Public Sector Resource Management: Given the limited impact of tax revenue allocations to education, healthcare, and infrastructure on GDP growth, improving the management and efficiency of public spending is crucial. The government should ensure that resources are effectively utilized in these sectors to drive tangible benefits for economic development.
- Promote Transparency and Accountability in Tax Revenue Allocation: Increased transparency in the allocation of tax revenues is essential for ensuring that funds directed to key sectors like education, healthcare, and infrastructure are used effectively. Strengthening oversight mechanisms and public accountability can help reduce inefficiencies and corruption.
- Foster a Business-Friendly Tax Environment: To stimulate private sector growth and improve tax compliance, the government should create a more business-friendly environment. This can include simplifying the tax process, reducing bureaucratic hurdles, and providing clearer tax guidelines, which can help businesses comply more easily while encouraging investment and innovation.
Limitations of the Study
The study is subject to several limitations that may impact the generalizability and depth of its findings. First, the research relies primarily on secondary data, which may limit the accuracy and comprehensiveness of the information, as it is constrained by the quality and availability of published reports. Additionally, the study covers a specific period from 2010 to 2023, which may not fully account for long-term trends or sudden economic shocks. The reliance on macroeconomic indicators such as GDP, VAT, and CIT rates also means that the analysis may overlook other critical factors influencing Nigeria’s economic growth, such as political instability, global economic conditions, or social factors. Furthermore, the study does not account for regional disparities within Nigeria, which could affect the broader national trends identified. Lastly, the use of statistical methods, while rigorous, may not capture all nuances of the complex relationship between tax policy and economic performance, limiting the depth of causal inferences.
