AN APPRAISAL OF ACCOUNTING SYSTEM IN THE PUBLIC SECTOR (A CASE STUDY OF BOARD OF INTERNAL REVENUE ENUGU STATE)

1.1 Background of the Study

An accounting system is a structured set of methods, procedures, controls, and records used by an organization to collect, record, classify, summarize, and report financial transactions. In the public sector, the accounting system is the backbone of financial management, enabling government entities to track revenues, control expenditures, safeguard assets, and produce financial reports for accountability purposes. An effective accounting system provides accurate, timely, and relevant financial information for decision-making by management, oversight bodies, and external stakeholders (citizens, legislators, creditors). The accounting system encompasses the chart of accounts, books of accounts (journals, ledgers), internal controls, financial reporting processes, and information technology infrastructure (Premchand, 2019; Chan, 2018).

Public sector accounting differs significantly from private sector accounting in its objectives and focus. While private sector accounting emphasizes profit determination and shareholder wealth maximization, public sector accounting emphasizes budgetary control, stewardship of public funds, accountability to citizens, and compliance with legal and regulatory requirements. The primary objectives of public sector accounting include: (a) providing information for budgetary control (ensuring expenditures do not exceed appropriations), (b) demonstrating compliance with laws, regulations, and financial rules, (c) safeguarding public assets from theft, waste, and mismanagement, (d) providing reliable financial information for decision-making by government officials and oversight bodies, (e) facilitating external audit and legislative oversight, and (f) promoting transparency and accountability to citizens (Mellett, 2019; Ogbeifun, 2019).

The Board of Internal Revenue (BIR) in Enugu State is a government agency responsible for assessing, collecting, and accounting for taxes and revenues due to Enugu State Government. Established under the Enugu State Revenue Administration Law, the BIR administers various taxes including Personal Income Tax (PAYE), Capital Gains Tax, Stamp Duties, Withholding Tax, Road Taxes, and other state levies and fees. The board is also responsible for accounting for all revenues collected, remitting them to the state treasury, and reporting on revenue performance. As a public sector entity, the BIR is required to maintain an accounting system that complies with the Enugu State Financial Regulations, Treasury Circulars, and the provisions of the Enugu State Revenue Administration Law (Enugu State Government, 2019; ESBIR, 2022).

The accounting system in the public sector, including the Board of Internal Revenue, is characterized by several distinctive features. Budgetary accounting is central to public sector accounting. Expenditures must not exceed budget appropriations, and financial records must track actual expenditures against budget. The accounting system must generate budget vs. actual reports for management and oversight bodies. Fund accounting is also used, where resources are segregated into funds (e.g., Consolidated Revenue Fund, statutory funds) based on their intended use. Each fund has its own self-balancing set of accounts (Premchand, 2019).

Cash basis accounting has historically been used in many Nigerian public sector entities, including state revenue authorities. Under cash basis accounting, transactions are recorded when cash is received or paid, not when economic events occur. While cash accounting is simple and provides information about cash flows, it does not capture liabilities (e.g., unpaid bills, pension obligations) or assets (e.g., infrastructure, equipment), providing an incomplete picture of the government’s financial position. In recent years, Nigeria has been transitioning to accrual accounting under the International Public Sector Accounting Standards (IPSAS). Accrual accounting records transactions when they occur, regardless of when cash is received or paid, providing a more complete and accurate picture (IPSASB, 2021; Chan, 2018).

The accounting system at the Board of Internal Revenue, Enugu State, faces several challenges common to public sector entities in Nigeria. Weak internal controls: Inadequate segregation of duties, lack of documentation, and poor physical security over cash and revenue records increase the risk of errors and fraud. Inadequate record-keeping: Manual or outdated accounting systems may lead to incomplete or inaccurate records, delayed reporting, and difficulty tracking revenue collections. Poor integration: Accounting systems may not be integrated with taxpayer registration, assessment, and collection systems, leading to reconciliation problems (Adebayo and Oyedokun, 2019).

Delayed financial reporting: Many public sector entities submit financial reports late (months or even years after the end of the fiscal year). Delayed reporting undermines the usefulness of financial information for decision-making and oversight. Weak internal audit: Internal audit departments are often understaffed and underfunded, limiting their ability to test controls and detect irregularities. Political interference: Political pressures may override controls, leading to unauthorized expenditures or revenue leakage (Okafor and Udeh, 2020).

The adoption of technology in public sector accounting has been a key reform initiative. The Enugu State Government has implemented various information technology systems to improve financial management, including the State Integrated Financial Management Information System (SIFMIS) and electronic revenue collection systems. For the Board of Internal Revenue, technology can enhance the accounting system through: (a) automated recording of revenue collections, (b) electronic reconciliation of collections with bank deposits, (c) real-time reporting of revenue performance, (d) improved internal controls (access controls, audit trails), and (e) integration with taxpayer databases (ESBIR, 2022; Okafor and Udeh, 2021).

The legal framework for public sector accounting in Enugu State includes the Enugu State Revenue Administration Law, the Financial Regulations, Treasury Circulars, the Public Procurement Act (at federal level, applicable to state entities receiving federal funds), and the Enugu State Fiscal Responsibility Law. The Board of Internal Revenue must comply with these laws and regulations in its accounting system. The Office of the Auditor-General of Enugu State conducts annual audits of the board’s financial statements and reports findings to the State House of Assembly (Enugu State Government, 2019; Ogbeifun, 2019).

An appraisal of the accounting system involves evaluating its effectiveness in achieving its objectives. Key criteria for appraisal include: (a) completeness: Are all revenue collections recorded? Are all expenditures properly documented? (b) accuracy: Are financial records free from material errors? (c) timeliness: Are financial reports prepared and submitted on time? (d) compliance: Do transactions comply with financial regulations and laws? (e) control: Are there adequate controls to prevent and detect errors and fraud? (f) relevance: Does the accounting system provide information useful for decision-making? (g) transparency: Is financial information accessible to oversight bodies and the public? (h) auditability: Can auditors verify the accuracy and completeness of financial records? (Premchand, 2019; Mellett, 2019).

The importance of an effective accounting system in the Board of Internal Revenue cannot be overstated. The board collects revenues that fund public services in Enugu State (education, healthcare, infrastructure, security). Weaknesses in the accounting system can lead to: (a) revenue leakage (unrecorded collections, theft of cash), (b) inaccurate reporting (misleading the state government and citizens), (c) audit queries and sanctions, (d) loss of public trust, and (e) difficulty in fiscal planning. Conversely, a strong accounting system supports: (a) revenue assurance, (b) accountability to citizens and the legislature, (c) effective management decision-making, (d) compliance with laws and regulations, and (e) public trust (Adebayo and Oyedokun, 2020).

Finally, this study focuses on the Board of Internal Revenue, Enugu State, as a case study because it is a key revenue-generating public sector entity where accounting system effectiveness directly affects state revenue. By appraising the accounting system at the board, the study can identify strengths, weaknesses, and areas for improvement, providing insights applicable to other state revenue authorities and public sector entities in Nigeria (Yin, 2018; Creswell and Creswell, 2018).

1.2 Statement of the Problem

The Board of Internal Revenue, Enugu State, is responsible for assessing, collecting, and accounting for taxes and revenues that fund public services in the state. An effective accounting system is essential for ensuring that all revenues are accurately recorded, properly accounted for, and timely reported to the state government and oversight bodies. However, evidence suggests that the accounting system at the board may face significant challenges. Preliminary observations and audit reports indicate potential problems: (a) weak internal controls over revenue collection (e.g., inadequate segregation of duties, missing receipts), (b) delays in financial reporting (late submission of revenue reports to the state government), (c) inaccurate record-keeping (discrepancies between collection records and bank deposits), (d) inadequate documentation (missing payment vouchers, receipts), (e) poor integration between revenue collection systems and accounting systems, (f) weak internal audit, and (g) compliance issues with financial regulations. These problems, if present, undermine the effectiveness of the accounting system, leading to revenue leakage, inaccurate reporting, audit queries, and erosion of public trust. There is a lack of recent, systematic, empirical research that appraises the accounting system at the Board of Internal Revenue, Enugu State. Therefore, this study is motivated to appraise the accounting system in the public sector, using the Board of Internal Revenue, Enugu State, as a case study.

1.3 Objectives of the Study

The specific objectives of this study are to:

1. Examine the current accounting system (records, procedures, controls, reporting) at the Board of Internal Revenue, Enugu State.
2. Assess the effectiveness of the accounting system in ensuring accurate, complete, and timely recording and reporting of revenue collections.
3. Evaluate the internal control mechanisms within the accounting system for preventing and detecting errors and irregularities.
4. Identify the challenges affecting the accounting system at the board (weak controls, inadequate records, delayed reporting, compliance issues).
5. Propose recommendations for improving the accounting system to enhance revenue assurance, accountability, and transparency at the Board of Internal Revenue, Enugu State.

1.4 Significance of the Study

This study is significant for several stakeholders. First, the management of the Board of Internal Revenue, Enugu State, will benefit from a systematic appraisal of the accounting system, enabling them to identify weaknesses, implement improvements, and enhance revenue assurance, accountability, and transparency. Second, the Enugu State Government (Ministry of Finance, State Treasury) will gain insights into the accounting challenges at the revenue board, informing policy, oversight, and resource allocation. Third, the Office of the Auditor-General of Enugu State will benefit from understanding accounting system weaknesses, informing audit planning and follow-up. Fourth, other state revenue authorities in Nigeria can use the findings as a benchmark for evaluating and improving their own accounting systems. Fifth, the Joint Tax Board and the Federal Inland Revenue Service (FIRS) will gain insights into state-level accounting challenges, informing coordination and technical assistance. Sixth, international development partners (World Bank, IMF, DFID/UKAID) will gain insights into public financial management challenges at the state level in Nigeria, informing technical assistance. Seventh, professional bodies (ICAN, ANAN, CITN) will find value in the study’s identification of accounting challenges in public sector revenue authorities, informing training and CPD programs. Eighth, academics and researchers in public sector accounting, public financial management, and revenue administration will benefit from the study’s contribution to the literature. Ninth, civil society organizations focused on governance and anti-corruption will gain evidence for advocacy for stronger financial management. Finally, citizens of Enugu State will benefit indirectly as improved accounting at the revenue board leads to better revenue collection, more efficient use of public funds, and improved public services.

1.6 Scope and Limitation of the Study

Scope of the Study

This study focuses on an appraisal of the accounting system in the public sector, using the Board of Internal Revenue, Enugu State, as a case study. Geographically, the research is limited to the Board of Internal Revenue, Enugu State, Nigeria. The board is the state government agency responsible for assessing, collecting, and accounting for taxes and revenues. Content-wise, the study examines the following areas: components of the accounting system (chart of accounts, books of accounts, internal controls, financial reporting, IT systems); effectiveness of the accounting system (accuracy, completeness, timeliness, compliance); internal controls (segregation of duties, authorization, documentation, reconciliations, physical security); challenges (weak controls, inadequate records, delayed reporting, compliance issues, integration problems); and improvement strategies. The study targets management (Chairman, Directors), accounting staff, internal auditors, and revenue officers. The time frame for data collection is the cross-sectional period of 2023–2024. The study does not cover other state revenue authorities (except for comparative context), nor does it cover the federal tax system (FIRS), nor does it cover substantive tax policy (except as it relates to accounting).

Limitation of the Study

This study acknowledges several limitations. First, the study is limited to one state revenue authority (Enugu State); findings may not be generalizable to all state revenue authorities in Nigeria. Second, the study relies on information from board staff and documents; the accuracy of information depends on the honesty of respondents and the quality of records. Third, access to sensitive financial records may be restricted due to confidentiality or security concerns. Fourth, the study is cross-sectional (a snapshot in time); the accounting system’s performance over a longer period is not fully captured. Fifth, the study does not include a comparative analysis with other state revenue authorities due to data availability constraints. Sixth, the study does not examine the impact of recent reforms (e.g., SIFMIS) in depth. Despite these limitations, the study aims to provide robust, meaningful insights into the accounting system at the Board of Internal Revenue, Enugu State.

CHAPTER TWO: REVIEW OF LITERATURE

2.1 Introduction

This chapter reviews the literature relevant to the appraisal of accounting systems in the public sector, with particular focus on government accounting, financial information, sources of cash and recording media, the nature and purpose of government accounting, fund accounting classification, basis of accounting, and depreciation. The literature review provides the theoretical and conceptual foundation for understanding the accounting system at the Board of Internal Revenue, Enugu State, and identifies best practices, challenges, and areas for improvement in public sector accounting.

2.2 Historical Development of Government Accounting

Government accounting has evolved significantly over centuries, reflecting changes in governance, public finance, and accountability demands. The origins of government accounting can be traced to ancient civilizations, where rulers maintained records of tax collections, expenditures, and assets. In ancient Egypt, scribes recorded grain collections and distributions; in ancient Rome, the “Tabulae Publicae” recorded public finances. However, these early systems were primarily for control and fraud prevention, not for public accountability (Premchand, 2019; Chan, 2018).

The modern development of government accounting is closely linked to the rise of democratic governance and the demand for public accountability. The English Reform Act of 1832 and the establishment of the Exchequer and Audit Department in 1866 marked significant milestones, introducing parliamentary oversight of government expenditures. The United States also developed government accounting standards through the General Accounting Office (now Government Accountability Office) established in 1921. The emergence of the welfare state in the 20th century expanded the scope of government activities, increasing the complexity of government accounting (Mellett, 2019).

In Nigeria, government accounting has its roots in the colonial era. The British colonial administration introduced the Treasury system, financial regulations, and annual budgeting. After independence in 1960, Nigeria inherited the British-style government accounting system, including the cash basis of accounting and fund accounting classification. The first indigenous financial regulations were issued in 1970s. The Nigerian government accounting system has undergone several reforms, including the introduction of the Treasury Single Account (TSA), the Government Integrated Financial Management Information System (GIFMIS), and the adoption of International Public Sector Accounting Standards (IPSAS) in 2012 (Ogbeifun, 2019; Adebayo and Oyedokun, 2019).

At the state level, including Enugu State, government accounting has historically followed the cash basis of accounting, with emphasis on budgetary control and compliance. State Boards of Internal Revenue maintain records of tax collections and remittances to the state treasury. In recent years, states have adopted computerised accounting systems (e.g., State Integrated Financial Management Information System – SIFMIS) and electronic revenue collection systems to improve efficiency and accountability (Okafor and Udeh, 2020).

2.3 Financial Information

Financial information in the public sector refers to the data and reports that provide quantitative information about the financial position, financial performance, and cash flows of government entities. Financial information is used by multiple stakeholders for various purposes: (a) management – for planning, budgeting, and control, (b) legislature – for oversight and appropriation decisions, (c) citizens and taxpayers – for assessing the performance of their government, (d) creditors and investors – for assessing creditworthiness, (e) auditors – for verifying the accuracy of financial statements, (f) international organizations – for economic analysis and development assistance (IPSASB, 2021; Premchand, 2019).

The key components of financial information in the public sector include:

Budget Information: Budgeted revenues and expenditures, budget releases (warrants), and actual vs. budget variances. This information supports fiscal discipline and legislative oversight.

Revenue Information: Collections from taxes, fees, levies, grants, and other sources. For the Board of Internal Revenue, Enugu State, revenue information includes Personal Income Tax (PAYE), Capital Gains Tax, Stamp Duties, Withholding Tax, Road Taxes, and other state levies.

Expenditure Information: Payments for personnel (salaries, allowances), overheads (utilities, maintenance, travel), capital projects (construction, equipment), and transfers (subsidies, grants). Expenditure information must be tracked by budget line to ensure compliance with appropriations.

Asset Information: Government-owned assets, including land, buildings, infrastructure (roads, bridges), equipment, and financial assets. Under accrual accounting, assets are recorded and depreciated (Chan, 2018).

Liability Information: Government debts (domestic and external), accounts payable, accrued expenses, and contingent liabilities (e.g., guarantees, legal claims). Under cash accounting, liabilities may not be recorded, limiting the usefulness of financial reports (Mellett, 2019).

Cash Flow Information: Cash inflows and outflows from operating, investing, and financing activities, supporting liquidity management.

For the Board of Internal Revenue, Enugu State, the quality of financial information (accuracy, completeness, timeliness) is critical for revenue assurance, accountability to the state government, and compliance with financial regulations (Adebayo and Oyedokun, 2020).

2.4 Sources of Cash and Recording Media

In the public sector, including the Board of Internal Revenue, Enugu State, cash is the primary medium of transaction. Understanding the sources of cash and the recording media used is essential for designing effective accounting systems and internal controls.

Sources of Cash:

1. Tax Revenues: Collections from Personal Income Tax (PAYE), Capital Gains Tax, Stamp Duties, Withholding Tax, and other taxes administered by the Board of Internal Revenue.
2. Non-Tax Revenues: Fees (e.g., licensing fees, permit fees), fines and penalties, interest income, rent from government properties, dividends from state-owned enterprises.
3. Statutory Allocations: Transfers from the Federation Account (federal revenue sharing) to the state government, which may be allocated to the Board of Internal Revenue for its operations.
4. Grants and Aids: Transfers from international donors, development partners, or other governments for specific projects or programs.
5. Other Receipts: Reimbursements, recoveries, loan repayments, and other miscellaneous receipts (Enugu State Government, 2019; Okafor and Udeh, 2020).

Recording Media are the documents and systems used to record cash transactions. They include:

1. Source Documents:
   • Receipts: Official acknowledgment of cash received, typically pre-numbered to prevent loss or misuse.
   • Payment Vouchers: Documents authorizing cash payments, supported by invoices, contracts, or other evidence.
   • Bank Deposit Slips: Records of cash deposited into bank accounts.
   • Bank Statements: Records of bank transactions, used for reconciliation.
2. Books of Accounts (Manual or Computerised) :
   • Cashbook: Records all cash receipts and payments, with columns for date, description, reference, receipt amount, payment amount, and balance.
   • Receipt Register: Chronological record of all receipts issued.
   • Payment Register: Chronological record of all payments made.
   • General Ledger: Summary of all transactions by account (e.g., tax revenue account, salaries account).
   • Subsidiary Ledgers: Detailed records for specific accounts (e.g., accounts receivable subsidiary ledger for outstanding taxes).
3. Computerised Systems:
   • Electronic Revenue Collection Systems: Automated recording of tax payments via bank transfers, internet banking, or point-of-sale (POS) terminals.
   • Integrated Financial Management Information Systems (IFMIS) : Systems like SIFMIS that integrate budgeting, accounting, and reporting.
   • Spreadsheets and Accounting Software: Excel, QuickBooks, or other software used for record-keeping (Romney and Steinbart, 2018; Hall, 2019).

For the Board of Internal Revenue, Enugu State, effective management of sources of cash and proper use of recording media are essential for revenue assurance. Internal controls over cash include: (a) segregation of duties (different persons handle receipting, recording, and depositing), (b) pre-numbered receipts, (c) daily banking of collections, (d) regular bank reconciliations, (e) surprise cash counts, and (f) audit trails (Premchand, 2019).

2.5 Nature and Purpose of Government Accounting

Government accounting is the process of recording, analyzing, classifying, summarizing, and reporting financial transactions of government entities. It differs from private sector accounting in its objectives, focus, and legal framework. The nature and purpose of government accounting are shaped by the unique characteristics of the public sector.

Nature of Government Accounting:

1. Budgetary Focus: Government accounting places strong emphasis on budgetary control. Expenditures must not exceed budget appropriations, and financial records must track actual expenditures against budget. Budget vs. actual reports are primary outputs.
2. Legal and Regulatory Compliance: Government accounting must comply with the Constitution, Financial Regulations, Treasury Circulars, Appropriation Laws, and other applicable laws. Non-compliance can result in audit queries, sanctions, or legal action.
3. Fund Accounting: Government accounting uses fund accounting, where resources are segregated into funds based on their intended use (e.g., Consolidated Revenue Fund, Development Fund). Each fund is a self-balancing set of accounts.
4. Public Accountability: Government accounting serves the purpose of demonstrating accountability to citizens, the legislature, and other stakeholders. Transparency and openness are essential.
5. Stewardship: Government accounting focuses on stewardship – the proper management and use of public resources entrusted to government officials.
6. Cash Basis (Historically) : Nigerian government accounting has historically been cash-based (transactions recorded when cash is received or paid). However, transition to accrual basis under IPSAS is ongoing (Chan, 2018; Mellett, 2019).

Purpose of Government Accounting:

1. To provide information for budgetary control: Ensuring that expenditures do not exceed appropriations and that revenues meet targets.
2. To demonstrate compliance: Showing that financial transactions comply with laws, regulations, and financial rules.
3. To safeguard public assets: Preventing theft, waste, and mismanagement of government assets.
4. To provide information for decision-making: Supporting fiscal planning, resource allocation, and policy formulation.
5. To facilitate external audit and legislative oversight: Providing auditable records for the Auditor-General and the Public Accounts Committee.
6. To promote transparency and accountability: Enabling citizens, civil society, and the media to assess government financial performance (Premchand, 2019; Ogbeifun, 2019).

For the Board of Internal Revenue, Enugu State, the purpose of government accounting includes ensuring that all revenues collected are accurately recorded, properly accounted for, and timely remitted to the state treasury. The accounting system must also support the board’s internal management and external reporting obligations (Adebayo and Oyedokun, 2019).

2.6 Fund Accounting Classification

Fund accounting is a distinctive feature of government accounting, where resources are segregated into funds based on their intended use. Each fund is a self-balancing set of accounts (assets, liabilities, fund balance, revenues, expenditures). The purpose of fund accounting is to ensure that resources are used only for their intended purposes and to demonstrate compliance with legal restrictions.

Common Fund Types in Nigerian Government Accounting:

1. Consolidated Revenue Fund (CRF) : The main operating fund of the government. All revenues (taxes, fees, statutory allocations) are paid into the CRF, and all operating expenditures are paid from the CRF. The CRF is established by the Constitution.
2. Development Fund: Used for capital projects (construction of roads, schools, hospitals, etc.). Resources are allocated from the CRF to the Development Fund for specific capital projects.
3. Statutory Funds: Funds established by law for specific purposes, including:
   • Federation Account: Distributions from federal revenue to states and local governments.
   • State Joint Local Government Account: Allocations to local governments.
   • Natural Resources Development Fund: For development of natural resources.
   • Stabilization Fund: For economic stabilization purposes.
4. Trust Funds: Funds held in trust by the government for specific beneficiaries (e.g., pension funds, scholarship funds).
5. Agency Funds: Funds held by the government as an agent for other entities (e.g., withheld taxes, deposits).
6. Special Funds: Funds established for specific purposes, such as road maintenance funds, education funds, etc. (IPSASB, 2021; Premchand, 2019).

For the Board of Internal Revenue, Enugu State, the primary focus is on the Consolidated Revenue Fund (collections are paid into the CRF). However, the board may also administer special funds or trust funds (e.g., withheld taxes). The accounting system must track collections by fund type to ensure proper allocation and reporting (Enugu State Government, 2019).

Fund Accounting Principles:

• Separate Accounting: Each fund has its own self-balancing set of accounts (assets, liabilities, fund balance, revenues, expenditures).
• Legal Compliance: Resources must be used only for the purposes specified in the fund’s enabling legislation or appropriation.
• Budgetary Control: Expenditures from each fund must not exceed appropriations for that fund.
• Reporting: Separate financial statements may be prepared for major funds, or fund information may be presented in the notes (Chan, 2018).

2.7 Basis of Accounting

The basis of accounting refers to the timing of recognition of transactions – when revenues and expenditures are recorded. The two primary bases of accounting are cash basis and accrual basis. A third basis, modified cash basis or modified accrual basis, is also used by some governments.

Cash Basis of Accounting:

Under the cash basis, transactions are recorded when cash is received or paid. Revenue is recognized when cash is collected; expenditure is recognized when cash is disbursed. The cash basis is simple and provides information about cash flows. However, it has significant limitations: (a) it does not capture liabilities (e.g., unpaid bills, pension obligations), (b) it does not capture assets (e.g., infrastructure, equipment), (c) it does not match revenues with the expenses incurred to generate them, and (d) it is susceptible to manipulation (timing of payments can shift reported results).

Historically, Nigerian government accounting (federal, state, and local) has been on a cash basis. The Financial Regulations prescribed cash accounting. State Boards of Internal Revenue, including Enugu State, have traditionally used cash basis accounting for revenue collection and reporting (Okafor and Udeh, 2020).

Accrual Basis of Accounting:

Under the accrual basis, transactions are recorded when they occur, regardless of when cash is received or paid. Revenue is recognized when it is earned; expenditure is recognized when the liability is incurred. The accrual basis provides a more complete and accurate picture of the government’s financial position and performance: (a) assets (including infrastructure) are recorded on the balance sheet, (b) liabilities (including pension obligations) are recorded, (c) revenues are matched with the expenses incurred to generate them, and (d) financial statements are more comparable to private sector entities.

The International Public Sector Accounting Standards (IPSAS) require accrual accounting for full IPSAS compliance. Nigeria adopted IPSAS in 2012, with a roadmap for transition from cash to accrual basis. The transition is ongoing, with federal government entities adopting accrual accounting; state governments are at various stages of implementation. For the Board of Internal Revenue, Enugu State, transition to accrual accounting would require: (a) recording of accounts receivable (uncollected taxes), (b) recording of deferred revenue (prepaid taxes), (c) recording of liabilities (unpaid refunds), and (d) depreciation of assets (IPSASB, 2021; IFRS Foundation, 2021).

Modified Cash Basis / Modified Accrual Basis:

Some governments use a modified basis – cash basis with some accrual adjustments (e.g., recording accounts receivable for major revenue sources, recording accounts payable for major expenditures). This basis may be used during the transition from cash to full accrual.

Implications for the Board of Internal Revenue, Enugu State:

Under cash basis, the board records revenue only when cash is collected from taxpayers. Unpaid taxes (accounts receivable) are not recorded on the balance sheet, potentially understating the state’s assets. Under accrual basis, the board would record tax revenue when it is assessed (when the tax liability arises), even if payment will be received later. The board would also record allowances for doubtful accounts (for taxes unlikely to be collected). The choice of basis affects reported revenue, assets, and compliance with IPSAS (Adebayo and Oyedokun, 2020).

2.8 Depreciation

Depreciation is the systematic allocation of the depreciable amount of an asset over its useful life. It represents the consumption of the asset’s economic benefits over time. Depreciation is relevant under accrual accounting, where assets are recorded on the balance sheet and the cost of using the asset is recognized as an expense over its useful life. Under cash accounting, depreciation is not recorded because assets are not capitalised (assets are recorded as expenditures when purchased).

Depreciation in the Public Sector:

Under IPSAS, public sector entities are required to depreciate property, plant, and equipment (except land, which has an indefinite useful life). The objectives of depreciation in the public sector include: (a) matching the cost of assets with the benefits derived from their use, (b) providing information about the consumption of assets, (c) supporting replacement planning and budgeting, (d) enabling calculation of full cost of services, and (e) complying with accounting standards (IPSASB, 2021).

Depreciation Methods:

1. Straight-Line Method: Depreciation expense is the same each year (cost minus residual value, divided by useful life). This is the most common method in the public sector due to its simplicity.
2. Reducing Balance Method: Depreciation expense decreases over time (fixed percentage applied to the carrying amount).
3. Units of Production Method: Depreciation expense varies based on actual usage (e.g., kilometers driven for vehicles).

Depreciable Assets include buildings, vehicles, equipment, furniture, infrastructure (roads, bridges, water systems). Land is not depreciated (it has indefinite useful life). Assets under construction (work-in-progress) are not depreciated until they are ready for use.

Useful Life is the period over which an asset is expected to be used by the entity. Useful lives are estimated based on factors such as: (a) expected usage, (b) expected wear and tear, (c) technological obsolescence, (d) legal or regulatory limits. For example, vehicles may have a useful life of 5-10 years; buildings may have 20-50 years; computer equipment may have 3-5 years (IPSASB, 2021).

Depreciation and the Board of Internal Revenue, Enugu State:

The board may own assets such as office buildings, vehicles, computers, office equipment, and furniture. Under cash accounting, these assets are recorded as expenditures when purchased, not as assets on the balance sheet. Under accrual accounting (IPSAS), the board would: (a) capitalise assets (record them on the balance sheet), (b) record depreciation expense each year, and (c) write off assets when disposed. The transition to accrual accounting would require the board to: (a) conduct a physical inventory of all assets, (b) determine the cost (or fair value) of each asset, (c) estimate useful lives, (d) calculate accumulated depreciation, and (e) develop policies for asset management and depreciation (Okafor and Udeh, 2021).

Challenges of Depreciation in the Public Sector:

1. Asset records: Many public sector entities lack complete asset registers, making it difficult to determine which assets should be depreciated.
2. Infrastructure assets: Valuing and depreciating infrastructure (roads, bridges, water systems) is complex.
3. Heritage assets: Assets with cultural, historical, or environmental significance (e.g., monuments) may not be depreciated under IPSAS.
4. Useful life estimation: Determining appropriate useful lives for diverse assets requires professional judgment.
5. Transition issues: Moving from cash accounting (no depreciation) to accrual accounting (depreciation required) requires significant capacity building (Mellett, 2019; Chan, 2018).

For the Board of Internal Revenue, Enugu State, adopting depreciation accounting would improve the accuracy of financial statements by reflecting the consumption of assets. However, the board would need to invest in asset management systems and staff training to implement depreciation effectively (Adebayo and Oyedokun, 2019).
