Chapter One — 1.1 Background to the Study

Tax Audit Practices has increasingly attracted the attention of researchers, regulators, and practitioners concerned with profitability of listed firms. This growing interest reflects the recognition that tax audit practices does not operate in isolation, but interacts with a wider set of institutional and market conditions found within Nigeria and Selected ECOWAS Member States.

Nigeria and Selected ECOWAS Member States 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 tax audit practices, there remains limited consensus on the precise nature of its relationship with profitability of listed firms, particularly within Nigeria and Selected ECOWAS Member States. Many organizations continue to make decisions about tax audit practices without a clear, evidence-based understanding of how those decisions ultimately affect profitability of listed firms. 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 Tax Audit Practices on profitability of listed firms in Nigeria and Selected ECOWAS Member States.
2. To assess the extent to which tax audit practices influences profitability of listed firms within the study area.
3. To identify the challenges associated with tax audit practices in relation to profitability of listed firms.
4. To recommend strategies for optimizing tax audit practices in order to improve profitability of listed firms.

1.4 Research Questions

1. What is the effect of tax audit practices on profitability of listed firms in Nigeria and Selected ECOWAS Member States?
2. To what extent does tax audit practices influence profitability of listed firms within the study area?
3. What challenges are associated with tax audit practices in relation to profitability of listed firms?
4. What strategies can be adopted to optimize tax audit practices in order to improve profitability of listed firms?

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 profitability of listed firms. For managers and practitioners within Nigeria and Selected ECOWAS Member States, the study provides practical insight into how tax audit practices can be better managed. Finally, it contributes to the academic literature on accounting 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 Tax Audit Practices and its relationship with profitability of listed firms within the context of Nigeria and Selected ECOWAS Member States. 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.
