Conceptual Review

 Taxation and Economic Growth

Taxation stands at the core of government finance and public administration, serving as a pivotal mechanism for generating revenue (Abu & Mohammed Gamal, 2022). The definition of taxation encompasses the compulsory levies imposed by the government on individuals and entities, with the primary objective of funding public services and infrastructure (Afonso & Leal, 2019). Taxation plays a fundamental role in funding government activities, including education, healthcare, and infrastructure development, thereby contributing to the overall socioeconomic development of a nation (Arnold et al., 2021).

The theoretical underpinnings of how taxation contributes to economic growth are rooted in several economic theories, with classical economic growth theory being one of the foundational frameworks. According to classical economists like Adam Smith and David Ricardo, taxation, when utilized judiciously, stimulates economic growth by providing necessary funds for public investments that enhance productivity (Romer, 2020). Additionally, endogenous growth theory posits that taxation can influence long-term economic growth through its impact on factors such as human capital accumulation and technological progress (Mertens & Ravn, 2021). These theoretical perspectives emphasize the positive role taxation can play in fostering economic development by facilitating investments in critical areas.

An overview of various types of taxes further elucidates the intricate relationship between taxation and economic growth. Income tax, a direct tax levied on individuals and corporations, is a significant contributor to government revenue (Atkinson & Stern, 1980). It has implications for economic growth by influencing disposable income and, consequently, consumption and investment patterns. On the other hand, sales tax, considered an indirect tax, is imposed on goods and services at the point of purchase (Schratzenstaleer et al., 2021). It can impact economic development by influencing consumer behaviour and market dynamics. The differential effects of these taxes highlight the importance of considering the diverse tax landscape when evaluating their implications on economic growth.

The choice and structure of taxes have significant implications for economic development. For instance, progressive taxation, which imposes higher rates on higher incomes, may contribute to reducing income inequality, fostering social cohesion, and promoting economic stability (Elshani et al., 2017). On the other hand, regressive taxes, where the tax burden falls disproportionately on lower-income individuals, may exacerbate inequality and hinder economic growth (Baiardi, 2019). The interplay between these tax structures and economic development underscores the importance of thoughtful tax policy formulation that aligns with broader economic goals (Alesina & Ardagna, 2020).

 Historical Trends in Tax Revenue Collection

The historical trends in tax revenue collection by the Ogun State Internal Revenue Service (OGIRS) form a critical aspect of understanding the dynamics of taxation and its impact on economic growth in the region. An examination of historical patterns provides valuable insights into the evolution of tax revenue, shedding light on the factors that have influenced its trajectory over time (Martinez-Vazquez et al., 2011).

Analyzing historical patterns involves tracing the growth or contraction of tax revenue collected by OGIRS over distinct periods. This examination allows for the identification of patterns, anomalies, and trends that characterize the historical performance of the tax collection apparatus. For instance, studies such as Ebiringa and Yadirichukwu (2022) have demonstrated how historical analyses of tax revenue can reveal cyclical patterns or specific events that had a pronounced impact on revenue collection.

The analysis extends to identifying key factors influencing fluctuations in tax revenue over time. These factors can encompass a range of economic, social, and policy-related variables. Economic cycles, changes in tax policies, shifts in industrial composition, and external shocks are among the factors that may contribute to variations in tax revenue (Babatunde et al., 2017). By scrutinizing these influences, the study aims to provide a comprehensive understanding of the dynamics that have shaped the ebb and flow of tax revenue collected by OGIRS.

Moreover, the identification of trends that may have shaped the current state of taxation in Ogun State adds depth to the historical analysis. By discerning enduring patterns or shifts in the way taxation has been approached and administered, the study aims to draw connections between past practices and present realities (Ibadin & Olugoke, 2021). For instance, if there has been a historical emphasis on a particular sector or tax type, understanding the reasons behind such trends can inform contemporary strategies for optimizing tax revenue.

The historical context also sets the stage for evaluating the effectiveness of past interventions and policies aimed at enhancing tax revenue. By assessing the outcomes of historical measures, policymakers gain insights into what has worked well and where challenges persist. Lessons learned from historical trends can inform the formulation of more targeted and effective policies for the future, aligning taxation strategies with broader economic development goals (Rosen, 2022).

Challenges and Opportunities in Tax System

The exploration of challenges and opportunities within the tax system operated by the Ogun State Internal Revenue Service (OGIRS) is essential for a comprehensive understanding of the dynamics influencing tax assessment, collection, and, consequently, economic growth in the region.

The examination begins with an exploration of the challenges faced by OGIRS in tax assessment and collection. These challenges can span a range of issues, including administrative hurdles, non-compliance by taxpayers, and economic factors impacting the ability to collect taxes effectively (Prillaman & Meier, 2022). Understanding these challenges is crucial for policymakers and administrators, as it provides insights into areas requiring targeted interventions. For instance, a detailed analysis may reveal specific sectors or types of taxes that pose challenges, allowing for the formulation of strategies tailored to address these issues.

Concurrently, an analysis of opportunities within the current tax system aims to identify areas where improvements or innovations can be leveraged to enhance revenue generation. Opportunities may arise from technological advancements, changes in economic structures, or modifications in tax policies that create favourable conditions for increased compliance and collection (Afonso et al., 2020). Evaluating these opportunities is instrumental in developing strategies that align with best practices and emerging trends in taxation.





In conducting a comprehensive examination of the impact of taxation on economic growth, a robust and well-structured methodology is imperative. This chapter outlines the research design, population of the study, sampling technique, sources and methods of data collection, data analysis procedures, and ethical considerations. By adhering to established research philosophies and methodologies, this study aims to contribute valuable insights to the existing literature on the subject.

Research Design

The research design is a critical aspect of any study, serving as a roadmap that outlines the overall approach and methodology employed to address research questions and achieve objectives. In the context of this investigation into the impact of taxation on economic growth in Ogun State, a quantitative survey research design has been strategically chosen. This decision is grounded in the study’s specific objectives and is aligned with the work of Saunders et al. (2019), renowned researchers in research methods for business students. A quantitative approach is deemed appropriate due to its inherent capability to collect numerical data, which proves vital in conducting a structured analysis and deriving statistical inferences.

The choice of a quantitative survey design is justified by its effectiveness in handling large sample sizes, as highlighted by Saunders et al. (2019). Given the diversity and complexity of factors influencing the relationship between taxation policies and economic growth, a substantial sample is crucial for obtaining statistically significant results. This approach allows for the generalization of findings to the broader population, enhancing the external validity of the study. By employing a survey design, the research aims to systematically capture and analyze data from a representative sample within Ogun State, enabling a comprehensive exploration of the intricate relationships between taxation policies and economic growth.

Furthermore, the survey design is particularly well-suited for investigating the nuanced dynamics between taxation policies and economic growth in Ogun State. The structured nature of the survey allows for the formulation of specific questions related to taxation practices, economic activities, and growth indicators. This structured approach aligns with the study’s objectives, enabling the collection of standardized responses that can be subjected to rigorous statistical analysis. Saunders et al. (2019) emphasize the importance of selecting a research design that aligns with the research questions and objectives, and in this case, the quantitative survey design is tailored to facilitate a comprehensive exploration of the intricate relationships between taxation policies and economic growth in Ogun State.
