Effect of Value Added Tax in Revenue Generation of Southwestern States in Nigeria (2016 -2020)

Effect of Value Added Tax on Revenue Generation in Southwestern States of Nigeria (2016–2020)

ABSTRACT

This study investigates how Value Added Tax (VAT) affects revenue generation in selected Southwestern states of Nigeria between 2016 and 2020. The research focuses on Lagos, Ogun, Osun, Ekiti, and Oyo States. It adopts a descriptive design, with data collected from the Federal Inland Revenue Service (FIRS) offices across the region. A total of seventy-seven valid responses were analyzed using the Chi-Square statistical method in SPSS.

Findings show a strong positive relationship between VAT and revenue generation in the states. VAT has improved government income; however, challenges such as low compliance, weak administration, and limited public awareness continue to hinder its effectiveness. Therefore, the study recommends stricter enforcement, improved transparency, and enhanced education on the role of VAT in sustaining state finances.

CHAPTER ONE

1.1 Background to the Study

Revenue generation remains a pressing challenge for Nigeria’s three tiers of government. Frequent budget deficits and inadequate funding for public projects highlight the need for alternative income sources beyond crude oil.

According to Myles (2000), a government’s financial strength depends on the size and efficiency of its revenue base. Effective collection and management of revenue are essential for sustainable development. Consequently, governments rely on taxation as a consistent means of raising funds.

Among various tax systems, consumption-based taxes such as the Value Added Tax (VAT) are often broad and stable. Leach (2003) noted that consumption taxes are easier to administer and provide a steady flow of income. VAT specifically taxes the value added to goods and services at every production and distribution stage until the final sale.

In 1993, Nigeria introduced VAT to replace the narrow and inefficient Sales Tax system. The policy came into full effect in January 1994 and quickly became one of the nation’s most significant non-oil revenue sources. The Federal Inland Revenue Service (FIRS) manages its administration.

Despite its potential, VAT remains controversial. Naiyeju (2009) argued that poor implementation and weak compliance have limited its success. Conversely, other scholars maintain that VAT has significantly boosted government revenue. These contrasting views create a need for further research, especially in Southwestern Nigeria, where economic activities and tax potential are high.

Therefore, this study examines how VAT contributes to revenue generation in Lagos, Ogun, Osun, Ekiti, and Oyo States between 2016 and 2020.

1.2 Statement of the Problem

Value Added Tax (VAT) is a consumption tax levied on the value added to goods and services at each production or distribution stage. The final consumer ultimately bears the cost. In Nigeria, VAT applies to seventeen categories of goods and twenty-four categories of services, while essentials such as food, medicine, and educational materials remain exempt.

However, the VAT system faces numerous challenges. Confusion about exempted items often results in inconsistent administration. Furthermore, applying a uniform tax rate to all products disregards income differences among consumers.

Attempts to increase VAT rates have also faced strong public resistance. For instance, the 2007 proposal to raise the rate from 5 percent to 10 percent triggered nationwide protests organized by the Nigeria Labour Congress (NLC), forcing the government to reverse the decision.

Transparency in managing VAT proceeds remains another concern. Several states still struggle with accountability and misuse of tax revenues. Consequently, public trust in the system has declined.

Given these issues, this study seeks to determine whether VAT has genuinely enhanced revenue generation in Southwestern states and to identify the factors that influence its effectiveness.

1.3 Objectives of the Study

The main objective of this study is to examine the effect of Value Added Tax on revenue generation in Southwestern Nigeria between 2016 and 2020.

The specific objectives are to:

1. Examine the relationship between VAT and revenue generation in Lagos State.

2. Determine the relationship between VAT and revenue generation in Ogun State.

3. Assess the relationship between VAT and revenue generation in Osun State.

4. Evaluate the relationship between VAT and revenue generation in Ekiti State.

5. Investigate the relationship between VAT and revenue generation in Oyo State.

1.4 Research Hypotheses

H₀₁: There is no significant relationship between VAT and revenue generation in Lagos State.
H₀₂: There is no significant relationship between VAT and revenue generation in Ogun State.
H₀₃: There is no significant relationship between VAT and revenue generation in Osun State.
H₀₄: There is no significant relationship between VAT and revenue generation in Ekiti State.
H₀₅: There is no significant relationship between VAT and revenue generation in Oyo State.

1.5 Significance of the Study

This study offers both practical and academic value. It provides policymakers and tax administrators with insights into how VAT influences state finances and highlights strategies to improve compliance and collection efficiency.

In addition, the study contributes to academic literature on taxation and fiscal management. Researchers and students will find it useful as a reference for future studies. Moreover, state governments can use the findings to strengthen VAT systems, enhance internally generated revenue, and reduce dependence on federal allocations.

1.6 Scope of the Study

The study focuses on the effect of VAT on revenue generation in five Southwestern states—Lagos, Ogun, Osun, Ekiti, and Oyo—covering the period 2016 to 2020. Data were collected from reports of the Federal Inland Revenue Service (FIRS) and the Central Bank of Nigeria (CBN).

The study limits its analysis to VAT and its connection to state-level revenue performance. Other taxes such as personal income tax and company income tax fall outside the study’s scope.
