Chapter One — 1.1 Background to the Study

Presumptive Tax Assessment has increasingly attracted the attention of researchers, regulators, and practitioners concerned with taxpayer satisfaction. This growing interest reflects the recognition that presumptive tax assessment does not operate in isolation, but interacts with a wider set of institutional and market conditions found within the Nigerian Oil and Gas Sector.

the Nigerian Oil and Gas Sector 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

While presumptive tax assessment is widely discussed in policy and industry circles, empirical evidence on its actual effect on taxpayer satisfaction within the Nigerian Oil and Gas Sector remains sparse and, in places, contradictory. This lack of localized, rigorous evidence makes it difficult for decision-makers to know with confidence whether current approaches to presumptive tax assessment are helping or hindering taxpayer satisfaction — a gap this study sets out to close.

1.3 Objectives of the Study

1. To examine the effect of Presumptive Tax Assessment on taxpayer satisfaction in the Nigerian Oil and Gas Sector.
2. To assess the extent to which presumptive tax assessment influences taxpayer satisfaction within the study area.
3. To identify the challenges associated with presumptive tax assessment in relation to taxpayer satisfaction.
4. To recommend strategies for optimizing presumptive tax assessment in order to improve taxpayer satisfaction.

1.4 Research Questions

1. What is the effect of presumptive tax assessment on taxpayer satisfaction in the Nigerian Oil and Gas Sector?
2. To what extent does presumptive tax assessment influence taxpayer satisfaction within the study area?
3. What challenges are associated with presumptive tax assessment in relation to taxpayer satisfaction?
4. What strategies can be adopted to optimize presumptive tax assessment in order to improve taxpayer satisfaction?

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 taxpayer satisfaction. For managers and practitioners within the Nigerian Oil and Gas Sector, 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

In terms of scope, this study confines itself to the Nigerian Oil and Gas Sector, focusing specifically on how presumptive tax assessment relates to taxpayer satisfaction within that setting. Findings are interpreted within these boundaries rather than as universal claims applicable to every organization or market.
