Project – Effect of Tax Compliance on the Profitability of Small and Medium Enterprises (SMEs) in Lagos State, Nigeria

CHAPTER ONE

INTRODUCTION

1.1 Background of the Study

Small and Medium Enterprises (SMEs) play a pivotal role in economic growth, employment generation, and poverty reduction in Nigeria. In Lagos State, SMEs constitute a significant portion of the formal and informal economy, contributing substantially to local GDP, innovation, and socio-economic development. However, the operational environment for these businesses is often shaped by regulatory requirements, including tax compliance. Tax compliance refers to the degree to which firms meet their statutory tax obligations—accurately reporting income, filing tax returns on time, and remitting due taxes as required by law (Salawu, Adigun, Lawal & Olaleye, 2025).

The profitability of SMEs reflects their ability to generate earnings relative to expenses and obligations, serving as a key indicator of business viability and growth potential. While proper tax compliance ensures legal conformity and access to benefits such as tax incentives and credit facilities, high compliance costs, complex filing procedures, and punitive enforcement measures can erode profit margins, reduce reinvestment capacity, and increase financial strain (Oloyede, Otusanya & Oloyede, 2025). Research has shown that tax administration and perceptions of tax justice significantly influence tax morale and compliance among SMEs in Lagos State, highlighting the connection between the tax framework and business behaviour (Oyedele, Alao & Ifayemi, 2025). Moreover, studies indicate that the introduction of electronic tax filing systems significantly improves compliance among SMEs, suggesting that the efficiency of compliance procedures can shape compliance levels (Salawu et al., 2025).

Despite these insights, there remains limited empirical evidence on how compliance affects the profitability of SMEs in Lagos State. SMEs often operate on narrow profit margins, and the costs associated with complying with multiple tax obligations—such as corporate income tax, value-added tax (VAT), and personal income tax remittances on behalf of employees—can have critical implications for financial performance and sustainability. Furthermore, Lagos State has introduced tax reforms intended to support SMEs, including exemptions and simplified filing processes, which may alter the relationship between compliance and profitability (Salawu et al., 2025). Consequently, an in-depth investigation into the effect of tax compliance on SME profitability is essential to inform policy, enhance business efficiency, and promote economic resilience in one of Nigeria’s largest commercial hubs.

1.2 Statement of the Problem

Tax compliance remains a major challenge for SMEs in Lagos State. Many businesses struggle with understanding tax obligations, navigating complex tax codes, and meeting filing deadlines due to limited financial and human resources. While ensuring compliance helps legitimize business operations and enables access to formal contracts and incentives, it can also introduce significant costs—both direct (tax liabilities) and indirect (compliance costs, penalties for late filing)—that may reduce net profitability.

Empirical studies indicate varied relationships between tax compliance frameworks and business performance. Some research suggests that tax administration has no significant effect on SME profitability, while other studies highlight the significant impact of taxation on productivity and business growth (Oloyede et al., 2025). Evidence from Lagos State also shows that electronic tax filing systems and perceptions of tax justice influence compliance behaviour, but there is limited data on how these compliance behaviours translate into profitability outcomes (Salawu et al., 2025; Oyedele et al., 2025). These gaps are further compounded by evolving tax reforms aimed at making the tax environment more SME-friendly (Salawu et al., 2025).

The lack of focused empirical research examining how tax compliance affects the profitability of SMEs in Lagos State limits policymakers, tax authorities, and business leaders from fully understanding the costs and benefits of compliance. Without this understanding, interventions aimed at enhancing compliance may inadvertently strain SME finances, discouraging growth and sustainability. This study therefore seeks to empirically investigate the effect of tax compliance on the profitability of SMEs in Lagos State.
