Chapter One — 1.1 Background to the Study

In recent years, Presumptive Tax Assessment has emerged as a critical factor shaping internally generated revenue across organizations operating in and around Selected Small and Medium Enterprises in Nigeria. As institutions grapple with the pressures of globalization, regulatory reform, and shifting stakeholder expectations, understanding how presumptive tax assessment relates to internally generated revenue has become an important area of both scholarly and practical concern.

Within the context of Selected Small and Medium Enterprises in Nigeria, this relationship carries particular significance. Organizations in this setting operate under a distinct combination of economic, regulatory, and market conditions that may amplify or dampen the effect of presumptive tax assessment on internally generated revenue, making a context-specific inquiry both timely and necessary.

1.2 Statement of the Problem

Despite a growing body of literature on presumptive tax assessment, there remains limited consensus on the precise nature of its relationship with internally generated revenue, particularly within Selected Small and Medium Enterprises in Nigeria. Many organizations continue to make decisions about presumptive tax assessment without a clear, evidence-based understanding of how those decisions ultimately affect internally generated revenue. This gap between practice and empirical understanding is the central problem this study seeks to address.

1. To examine the effect of Presumptive Tax Assessment on internally generated revenue in Selected Small and Medium Enterprises in Nigeria.
2. To assess the extent to which presumptive tax assessment influences internally generated revenue within the study area.
3. To identify the challenges associated with presumptive tax assessment in relation to internally generated revenue.
4. To recommend strategies for optimizing presumptive tax assessment in order to improve internally generated revenue.

1.4 Research Questions

1. What is the effect of presumptive tax assessment on internally generated revenue in Selected Small and Medium Enterprises in Nigeria?
2. To what extent does presumptive tax assessment influence internally generated revenue within the study area?

1.5 Significance of the Study

This study is significant to a range of stakeholders. For policymakers and regulators, the findings offer evidence to guide the design of frameworks that support healthier outcomes around internally generated revenue. For managers and practitioners within Selected Small and Medium Enterprises in Nigeria, the study provides practical insight into how presumptive tax assessment can be better managed. Finally, it contributes to the academic literature on taxation by extending existing knowledge into a specific empirical context, and offers a reference point for future researchers.

1.6 Scope of the Study

The study is limited to an examination of Presumptive Tax Assessment and its relationship with internally generated revenue within the context of Selected Small and Medium Enterprises in Nigeria. It reflects a clearly defined scope of analysis and relies on data and perspectives available within that scope; generalizing the findings beyond this specific context should therefore be done with appropriate caution.
