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 Commercial Banks 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.

Selected Commercial Banks in Nigeria presents a useful setting for examining this relationship precisely because the conditions there — structural, regulatory, and behavioural — differ from those typically assumed in the broader literature, most of which draws on evidence from more developed economies.

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 Commercial Banks 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.

1.3 Objectives of the Study

1. To examine the effect of Presumptive Tax Assessment on internally generated revenue in Selected Commercial Banks 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 Commercial Banks in Nigeria?
2. To what extent does presumptive tax assessment influence internally generated revenue within the study area?
3. What challenges are associated with presumptive tax assessment in relation to internally generated revenue?
4. What strategies can be adopted to optimize presumptive tax assessment in order to improve internally generated revenue?

1.5 Significance of the Study

Beyond its academic contribution to the field of taxation, this study has practical value for management teams within Selected Commercial Banks in Nigeria seeking to understand how presumptive tax assessment translates into measurable outcomes around internally generated revenue. It is equally useful to students and future researchers looking for a localized empirical reference on this relationship.

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 Commercial Banks 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.
