Project – Effect of Treasury Single Account (TSA) Implementation on Financial Accountability in Federal Ministries in Nigeria

CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Public financial management reforms worldwide emphasize improved cash management, transparency, and reduction of leakages in government finances. The Treasury Single Account (TSA) is a consolidated structure of government bank accounts that enables the government to operate a unified banking arrangement for the receipts and payments of government (International Monetary Fund [IMF], 2010). The TSA centralizes cash balances, enhances liquidity management, reduces borrowing costs, and improves reconciliation between fiscal and banking records—all of which are expected to strengthen financial accountability (IMF, 2011).

In Nigeria, the Federal Government intensified TSA implementation following directives and operational guidelines issued to federal ministries, departments, and agencies (MDAs). The Central Bank of Nigeria (CBN) and the Office of the Accountant-General of the Federation (OAGF) released operational circulars to consolidate government deposits and to formalize e-collection mechanisms for federal revenues (CBN, 2015; OAGF, n.d.). The policy aimed to end the practice of maintaining multiple government accounts across commercial banks that often created idle balances, weak monitoring, and opportunities for leakage.

Empirical evidence from Nigeria and other developing countries indicates mixed outcomes. Several studies report improvements in cash visibility, reduction in idle funds, and enhanced control over public resources after TSA adoption (World Bank, 2019; Udoikah, 2024). Conversely, other investigations highlight implementation challenges such as inadequate integration of MDAs into the TSA ecosystem, delays in remittances, weak internal controls, and reconciliation problems (Adebisi & Okike, 2022). These mixed findings make it important to assess specifically how TSA implementation has affected financial accountability within federal ministries—the key custodians of recurrent and capital expenditures at the center of government.

1.2 Statement of the Problem

Financial accountability in public sector organizations remains a central policy objective in Nigeria. Prior to TSA, fragmented government accounts across multiple banks limited the Federal Government’s ability to track revenue flows and created room for misappropriation and delayed reconciliation (Pattanayak & Fainboim, 2010). While TSA promises greater transparency and accountability, practical experiences reveal several implementation issues such as poor ICT infrastructure, inadequate training, and capacity gaps in MDAs (Udoikah, 2024).

Some studies assert that TSA has reduced leakages and improved fiscal reporting (World Bank, 2019), while others claim the improvements are marginal or uneven across ministries (Adebisi & Okike, 2022). Thus, there is a gap in robust ministry-level evidence about whether TSA has produced measurable improvements in financial accountability within federal ministries, and which specific accountability dimensions—such as timely reconciliations, reduction of irregularities, audit outcomes, and internal control effectiveness—have actually changed. This study seeks to fill that gap by empirically assessing the effect of TSA implementation on financial accountability in selected federal ministries in Nigeria.

1.3 Objectives of the Study

The general objective of this study is to assess the effect of TSA implementation on financial accountability in federal ministries in Nigeria.
The specific objectives are to:

1. Examine changes in revenue remittance and reconciliation practices in federal ministries after TSA implementation.

2. Evaluate the extent to which TSA has influenced internal controls and audit outcomes in selected federal ministries.

3. Determine the impact of TSA on the incidence of financial irregularities and unremitted revenues within the ministries.

4. Identify implementation challenges that limit TSA’s effectiveness in improving financial accountability.

5. Propose recommendations to enhance the effectiveness of TSA for better financial accountability in federal ministries.

1.4 Research Questions

This study will answer the following research questions:

1. How has TSA implementation changed revenue remittance and reconciliation practices in federal ministries?

2. To what extent has TSA influenced internal control systems and audit findings in the ministries?

3. What effect has TSA had on the incidence of financial irregularities and unremitted revenues?

4. What are the major implementation challenges facing TSA in federal ministries?

5. What policy and operational measures can improve TSA’s contribution to financial accountability?

1.5 Research Hypothesis

To guide the study, the following hypothesis is formulated and will be empirically tested:

H₀: Treasury Single Account (TSA) implementation has no significant effect on financial accountability in federal ministries in Nigeria.
H₁: Treasury Single Account (TSA) implementation has a significant effect on financial accountability in federal ministries in Nigeria.

1.6 Significance of the Study

This research is significant for several stakeholders. For policymakers and treasury managers, the study provides empirical evidence on the effectiveness of TSA in strengthening accountability at the ministry level, guiding further refinements in cash management and e-collection policies (IMF, 2010; World Bank, 2019). For auditors, anti-corruption agencies, and oversight institutions, the findings can inform targeted audit programs and reconciliation processes to close residual leakage points.

For academics, the study expands the literature on public financial management reform impacts in developing economies, offering empirical data on ministry-level outcomes (Udoikah, 2024). Finally, the research offers practical recommendations to MDAs and the OAGF/CBN on operational measures to improve integration, reconciliation, and transparency.

1.7 Scope of the Study

This study focuses on selected Federal Ministries of the Federal Republic of Nigeria. It examines financial accountability indicators such as revenue remittance compliance, timeliness and quality of bank reconciliation, incidence of irregularities in audited accounts, and the effectiveness of internal controls. The temporal scope covers the period from 2015—when full TSA implementation began—to 2024, to enable pre- and post-implementation analysis. The study excludes state-level governments and local government councils, which have different TSA arrangements and implementation dynamics (CBN, 2015).

1.8 Limitations of the Study

Possible limitations include restricted access to some internal ministry financial records, reluctance of staff to provide candid responses on sensitive matters, and the challenge of isolating TSA effects from other concurrent reforms (Adebisi & Okike, 2022). To mitigate these limitations, the study will rely on a combination of primary survey data, interviews with key officials, and secondary data (audit reports, bank reconciliation records, OAGF circulars), ensuring confidentiality and using triangulation to enhance validity.

1.9 Operational Definition of Terms

• Treasury Single Account (TSA): A unified structure of government bank accounts that consolidates all government cash resources into one account (IMF, 2010).

• Financial Accountability: The obligation of public institutions to report on the stewardship of public funds, ensure efficient use of resources, prevent misappropriation, and provide accurate and timely financial information to oversight bodies (World Bank, 2019).

• Reconciliation: The process of matching and resolving differences between bank records and an organization’s accounting ledgers (CBN, 2015).

• MDAs: Ministries, Departments, and Agencies of the Federal Government of Nigeria (OAGF, n.d.).

• e-Collection: Electronic mechanisms (platforms/agents) used to collect and channel revenues into designated government accounts (CBN, 2015).

1.10 Organization of the Study

The study is organized into five chapters. Chapter One presents the introduction, problem statement, objectives, research question, hypothesis, significance, scope, and definitions. Chapter Two will review relevant literature and theoretical frameworks on TSA and financial accountability. Chapter Three outlines the research design, population, sampling techniques, data collection methods, and analytical procedures. Chapter Four presents the data analysis and interpretation of findings. Chapter Five provides conclusions, policy recommendations, and suggestions for further research.
