APPRAISAL OF VALUE ADDED TAX LAW AND ADMINISTRATION IN NIGERIA

CHAPTER ONE: INTRODUCTION

1.1 Background of the Study

Value Added Tax (VAT) is a consumption tax levied on the value added to goods and services at each stage of the production and distribution chain. Unlike a sales tax, which is levied only at the final point of sale to the consumer, VAT is collected at every stage of production and distribution, but businesses are entitled to deduct the VAT they have paid on their inputs (input VAT) from the VAT they charge on their outputs (output VAT). This mechanism ensures that VAT is ultimately borne by the final consumer, and businesses act as collectors on behalf of the government. VAT is a broad-based tax, typically covering most goods and services, though many countries exempt certain categories (e.g., basic food items, education, healthcare, financial services) and zero-rate others (e.g., exports) (Bird and Gendron, 2018; Tait, 2019).

Value Added Tax was introduced in Nigeria on January 1, 1994, by the Value Added Tax Act No. 102 of 1993. The introduction of VAT was part of a broader tax reform aimed at diversifying government revenue away from heavy reliance on oil revenues, which were subject to price volatility. Before the introduction of VAT, Nigeria operated a sales tax system at the state level, but it was inefficient, poorly administered, and generated limited revenue. The shift to VAT was also recommended by international financial institutions (IMF, World Bank) as part of structural adjustment programs. Since its introduction, VAT has become a significant source of government revenue, contributing billions of Naira annually to the Federation Account (FIRS, 2020; Adebayo and Oyedokun, 2019).

The Value Added Tax Act (VATA) has been amended several times, most notably by the VAT (Amendment) Act of 2007, the VAT (Amendment) Act of 2015, and the Finance Acts of 2019, 2020, and 2021. Key provisions of the VAT Act include:

Registration: Businesses with annual turnover above a specified threshold (currently N25 million) are required to register for VAT. Registered businesses are required to charge VAT on their taxable supplies (output VAT), file regular VAT returns (monthly), and remit collected VAT to the Federal Inland Revenue Service (FIRS).

VAT Rate: The standard VAT rate in Nigeria is 7.5% (increased from 5% effective February 1, 2020). The rate applies to most goods and services, except those that are exempt or zero-rated.

Exempt Goods and Services: Certain goods and services are exempt from VAT, meaning that no VAT is charged on them, and businesses cannot deduct input VAT related to exempt supplies. Exempt items include: (a) basic food items (e.g., unprocessed agricultural products, bread, milk, eggs, fish), (b) medical and pharmaceutical products, (c) educational materials and services, (d) books and newspapers, (e) fertilizers, (f) baby products, and (g) services of community banks and mortgage institutions (FIRS, 2020).

Zero-Rated Goods and Services: Certain goods are zero-rated (0% VAT), meaning that VAT is charged at 0% on them, and businesses can deduct input VAT related to zero-rated supplies. Zero-rated items include: (a) non-oil exports, (b) goods and services purchased by diplomats, (c) goods and services for use in humanitarian donor-funded projects, and (d) goods and services for use in Export Processing Zones (EPZs).

Input-Output Mechanism: Registered businesses can deduct VAT paid on their inputs (input VAT) from VAT collected on their outputs (output VAT). If output VAT exceeds input VAT, the business remits the difference to FIRS. If input VAT exceeds output VAT (excess input VAT), the business may carry forward the excess to subsequent months or, in some cases, apply for a refund (FIRS, 2020).

The administration of VAT in Nigeria is the responsibility of the Federal Inland Revenue Service (FIRS). The FIRS is responsible for: (a) registering VAT taxpayers, (b) collecting VAT returns and payments, (c) auditing VAT taxpayers to ensure compliance, (d) investigating VAT fraud and evasion, (e) providing taxpayer education and guidance, (f) processing VAT refunds, and (g) enforcing penalties for non-compliance (FIRS, 2019). The FIRS has implemented several initiatives to improve VAT administration, including:

• Integrated Tax Administration System (ITAS) : An automated system for taxpayer registration, filing, payment, and reporting.
• Electronic VAT (e-VAT) : An online platform for VAT registration, return filing, and payment.
• VAT Automation: Automated reconciliation of input VAT claims with supplier data to detect fraudulent claims.
• Joint Tax Board (JTB) : Coordination of VAT administration across federal and state tax authorities.
• Taxpayer Education: Workshops, seminars, and online resources to educate taxpayers on VAT compliance (FIRS, 2020).

Despite these initiatives, the administration of VAT in Nigeria faces significant challenges. These include:

Low Compliance: Many eligible businesses fail to register for VAT, fail to file returns, or under-declare their taxable turnover. The informal sector, which constitutes a significant portion of the Nigerian economy, is largely outside the VAT net.

VAT Fraud and Evasion: Common VAT fraud schemes include: (a) issuing fictitious VAT invoices to claim fraudulent input VAT deductions, (b) under-declaring output VAT (charging customers VAT but not remitting it to FIRS), (c) over-declaring input VAT (inflating purchases), (d) missing trader fraud (carousel fraud), and (e) VAT registration fraud (using fake business identities).

Refund Processing Delays: Businesses with excess input VAT (e.g., exporters with zero-rated supplies) face long delays (months or years) in obtaining VAT refunds from FIRS. Delays create cash flow problems for businesses and reduce compliance incentives.

Complexity of VAT Rules: The distinction between exempt, zero-rated, and standard-rated supplies is often unclear, leading to disputes and errors. The VAT Act contains ambiguities and gaps that create compliance challenges.

Weak Audit Capacity: The FIRS has limited capacity to audit VAT taxpayers effectively due to insufficient staff, training, and technology. Many VAT audits are desk-based (document review) rather than field audits, and data analytics for detecting fraud are underutilized.

Lack of Harmonization Across States: VAT is a federal tax, but states have expressed concerns about the distribution of VAT revenues (discussed below). Some states have introduced parallel consumption taxes (e.g., sales taxes), creating compliance burdens for businesses operating nationwide.

Political and Legal Challenges: The distribution of VAT revenues between the federal government and states has been a contentious issue. Some states have challenged the constitutionality of the FIRS administering VAT, arguing that VAT is a state tax. The Supreme Court has ruled on this issue, but political tensions remain (Adebayo and Oyedokun, 2020).

The distribution of VAT revenues is governed by the VAT Act and the Federation Account Allocation Committee (FAAC) formula. VAT revenues are distributed as follows:

• 15% to the Federal Government
• 50% to State Governments
• 35% to Local Government Councils

Additionally, 4% of VAT revenues is retained by the FIRS for administrative costs (collection cost), and 20% of the states’ share is distributed based on equality (equal share to each state), 50% based on population, and 30% based on internally generated revenue (IGR) (FIRS, 2020). The distribution formula has been criticized as unfair because it does not adequately reflect the contribution of each state to VAT generation. States with high economic activity (Lagos, Rivers, Kano) generate more VAT but receive a smaller share relative to their contribution. This has led to legal challenges, including a lawsuit by the Lagos State Government against the FIRS (Adebayo and Oyedokun, 2019).

The appraisal of VAT law and administration involves evaluating whether the VAT system achieves its objectives: (a) revenue generation, (b) neutrality (not distorting business decisions), (c) simplicity (low compliance and administrative costs), (d) efficiency (minimizing economic distortions), (e) equity (fair distribution of tax burden), (f) transparency, and (g) ease of administration. Appraisal criteria include:

Revenue Productivity: Is VAT generating the expected revenue? Is the revenue yield increasing over time? Is the cost of collection (FIRS administrative costs) reasonable relative to revenue generated?

Compliance Rate: What percentage of eligible businesses are registered for VAT? What percentage of registered businesses file returns on time and remit collected VAT? What is the level of voluntary compliance?

VAT Gap: The difference between potential VAT revenue (what would be collected if all businesses complied fully) and actual VAT revenue collected. The VAT gap is an indicator of non-compliance and weak administration.

Cost of Collection: FIRS administrative costs as a percentage of VAT revenue collected. Lower percentages indicate more efficient administration.

Refund Processing Time: Average time between a business applying for a VAT refund and receiving payment. Shorter times indicate more efficient administration.

Taxpayer Satisfaction: Survey-based measures of taxpayer satisfaction with VAT registration, filing, payment, audit, and refund processes (Tait, 2019; Bird and Gendron, 2018).

The Finance Acts of 2019, 2020, and 2021 introduced several changes to the VAT system, including:

• Increase in VAT rate from 5% to 7.5% (effective February 1, 2020)
• Expansion of the list of exempt goods and services
• Introduction of VAT on non-oil exports (zero-rated, not exempt)
• Clarification of VAT treatment of certain transactions (e.g., e-commerce, digital services)
• Enhanced penalties for non-compliance (late filing, under-declaration)
• Introduction of electronic invoicing and real-time reporting requirements for large taxpayers (FIRS, 2021)

These changes are intended to improve VAT revenue generation, broaden the tax base, and enhance compliance. However, their impact on VAT administration and compliance is not yet fully understood.

The theoretical framework for VAT is based on the principle of consumption taxation. VAT is preferred over sales tax because it avoids “cascading” (tax on tax) and is neutral with respect to production methods (tax does not favour capital-intensive over labour-intensive production). VAT is also difficult to evade because the input-output mechanism creates a paper trail. However, VAT is regressive (disproportionately affects low-income households) unless exemptions for basic goods are provided (Bird and Gendron, 2018).

Finally, this study focuses on an appraisal of Value Added Tax law and administration in Nigeria. By examining the legal framework, administrative practices, compliance levels, and revenue performance, the study will identify strengths, weaknesses, and areas for reform. The findings will provide insights for policymakers, tax administrators, taxpayers, and other stakeholders (Yin, 2018; Creswell and Creswell, 2018).

1.2 Statement of Problem

The Value Added Tax (VAT) was introduced in Nigeria in 1994 to diversify government revenue away from oil and to create a stable, broad-based tax source. Over the past three decades, VAT has become a significant revenue source, contributing billions of Naira annually to the Federation Account. However, the VAT system in Nigeria faces significant challenges that undermine its effectiveness, efficiency, and equity. Specific problems include:

1. Low Compliance Rates: Many eligible businesses fail to register for VAT, fail to file returns, or under-declare their taxable turnover. The informal sector, which constitutes a significant portion of the Nigerian economy, is largely outside the VAT net. Compliance rates are low, resulting in a substantial VAT gap (difference between potential and actual revenue).
2. VAT Fraud and Evasion: Common fraud schemes include fictitious VAT invoices (claiming false input VAT deductions), under-declaration of output VAT (charging customers VAT but not remitting to FIRS), missing trader fraud (carousel fraud), and registration fraud (using fake business identities). Weak enforcement and detection allow fraud to persist.
3. Refund Processing Delays: Businesses with excess input VAT (e.g., exporters with zero-rated supplies, manufacturers with high input costs) face long delays (6-24 months) in obtaining VAT refunds from FIRS. Refund delays create cash flow problems for businesses, reduce compliance incentives, and may lead to protests or legal action.
4. Complexity of VAT Rules: The distinction between exempt, zero-rated, and standard-rated supplies is often unclear, leading to disputes and errors. The VAT Act contains ambiguities, gaps, and outdated provisions that create compliance challenges and opportunities for avoidance.
5. Weak Audit Capacity: The FIRS has limited capacity to audit VAT taxpayers effectively due to insufficient staff, training, and technology. Many VAT audits are desk-based (document review) rather than field audits, and data analytics for detecting fraud are underutilized. Audit coverage is low (small percentage of taxpayers audited annually).
6. Lack of Harmonization Across States: VAT is a federal tax, but some states have introduced parallel consumption taxes (e.g., sales taxes), creating compliance burdens for businesses operating nationwide. The multiplicity of taxes increases compliance costs and may lead to double taxation.
7. Political and Legal Challenges: The distribution of VAT revenues between the federal government and states has been contentious. Some states have challenged the constitutionality of the FIRS administering VAT, arguing that VAT is a state tax. Uncertainty about the legal and political framework creates risk for businesses.
8. Inadequate Taxpayer Education: Many businesses, especially small and medium enterprises (SMEs), do not understand their VAT obligations (registration, filing, remittance, record-keeping). Lack of awareness leads to unintentional non-compliance.
9. Technology Limitations: While the FIRS has implemented IT systems (ITAS, e-VAT), these systems have limitations (downtime, user unfriendliness, integration issues). Technology limitations hinder efficient registration, filing, payment, and refund processing.
10. Impact of VAT Rate Increase: The VAT rate was increased from 5% to 7.5% in February 2020. The impact of the rate increase on compliance, consumption, inflation, and revenue is not yet fully understood.

There is a lack of recent, systematic, empirical research that appraises the VAT law and administration in Nigeria, including legal analysis, administrative practices, compliance levels, fraud detection, refund processing, and revenue performance. Therefore, this study is motivated to appraise the Value Added Tax law and administration in Nigeria.

1.3 Objectives of the Study

The specific objectives of this study are:

1. To examine the legal framework for Value Added Tax (VAT) in Nigeria, including the VAT Act, amendments, and relevant Finance Acts.
2. To assess the administrative practices of the Federal Inland Revenue Service (FIRS) in registering VAT taxpayers, collecting returns, conducting audits, processing refunds, and enforcing compliance.
3. To evaluate the revenue performance of VAT in Nigeria (trends in VAT revenue, contribution to total tax revenue, cost of collection, VAT gap).
4. To identify the compliance levels of VAT taxpayers (registration rates, filing rates, remittance rates) and the factors affecting compliance.
5. To identify the challenges facing VAT administration in Nigeria (low compliance, fraud, refund delays, complexity, weak audit capacity, harmonization, political issues, technology).
6. To propose recommendations for reforming VAT law and administration in Nigeria to improve revenue generation, compliance, efficiency, and equity.

1.4 Research Questions

The following research questions guide this study:

1. What are the key provisions of the Value Added Tax Act and related legislation (Finance Acts) governing VAT in Nigeria?
2. How does the Federal Inland Revenue Service (FIRS) administer VAT in Nigeria (registration, filing, payment, audit, refund, enforcement)?
3. What is the revenue performance of VAT in Nigeria (trends in VAT revenue, contribution to total tax revenue, cost of collection, VAT gap)?
4. What are the compliance levels of VAT taxpayers in Nigeria (registration rates, filing rates, remittance rates)?
5. What are the major challenges facing VAT administration in Nigeria (low compliance, fraud, refund delays, complexity, weak audit capacity, harmonization, political issues, technology)?
6. What reforms can be implemented to improve VAT law and administration in Nigeria?

1.5 Statement of Research Hypotheses

Hypothesis Three (Refund Processing)

• H₀: There is no significant difference between the actual time taken to process VAT refunds and the statutory time limit in Nigeria.
• H₁: There is a significant difference between the actual time taken to process VAT refunds and the statutory time limit in Nigeria.

Hypothesis Four (Challenges)

• H₀: Challenges such as low compliance, fraud, refund delays, complexity, weak audit capacity, harmonization issues, political issues, and technology limitations do not significantly affect VAT administration in Nigeria.
• H₁: Challenges such as low compliance, fraud, refund delays, complexity, weak audit capacity, harmonization issues, political issues, and technology limitations significantly affect VAT administration in Nigeria.

1.6 Significance of the Study

This study is significant for several stakeholders:

Federal Inland Revenue Service (FIRS) : The findings will help FIRS identify weaknesses in VAT administration (compliance, fraud, refunds, audits, technology) and design targeted interventions to improve efficiency, effectiveness, and revenue generation.

Federal Ministry of Finance, Budget and National Planning: The findings will inform policy decisions on VAT rate, exemptions, zero-rating, revenue distribution, and administrative reforms.

National Assembly (Finance Committees) : The findings will inform legislative oversight of VAT administration and consideration of amendments to the VAT Act and Finance Acts.

State Governments: The findings will inform state governments about the VAT system and its impact on state revenues, as well as the potential for harmonising state consumption taxes with federal VAT.

Taxpayers (Businesses and Individuals) : The findings will help taxpayers understand their VAT obligations, the challenges facing the system, and the need for compliance. Taxpayers will also benefit from recommendations to simplify VAT administration and improve refund processing.

Tax Practitioners and Consultants: The findings will provide insights for advising clients on VAT compliance, risk management, and dispute resolution.

Academics and Researchers: The study contributes to the literature on VAT in developing countries, particularly in Africa, and provides a basis for further research.

Professional Bodies (ICAN, ANAN, CITN) : The findings will inform training and CPD programs on VAT for their members.

International Development Partners (IMF, World Bank) : The findings will inform technical assistance programs on VAT reform in Nigeria.

The Nigerian Economy: Improved VAT law and administration will lead to higher revenue generation, reduced reliance on oil, improved fiscal sustainability, and enhanced economic development.

1.7 Scope of the Study

This study focuses on the appraisal of Value Added Tax law and administration in Nigeria. The scope is limited to:

Legal Framework: The Value Added Tax Act (VATA) and amendments, including the Finance Acts of 2019, 2020, and 2021. The study also examines relevant regulations, guidelines, and judicial decisions.

Administration: The practices of the Federal Inland Revenue Service (FIRS) in administering VAT, including registration, filing, payment, audit, refund, and enforcement.

Time Period: The study covers the period 2014-2023 (10 years) to capture trends before and after the VAT rate increase (5% to 7.5% in February 2020). The period also includes the implementation of the Finance Acts.

Geographical Scope: Nigeria (federal level), with reference to state-level issues (VAT distribution, state consumption taxes) where relevant.

VAT Taxpayers: The study covers registered VAT taxpayers across sectors: manufacturing, wholesale and retail, services, oil and gas, telecommunications, banking and finance, construction, and others.

Key Appraisal Areas: (a) legal framework (adequacy, clarity, consistency), (b) administrative practices (efficiency, effectiveness, transparency), (c) revenue performance (trends, contribution, cost of collection, VAT gap), (d) compliance levels (registration, filing, remittance), (e) challenges (low compliance, fraud, refund delays, complexity, weak audit capacity, harmonization, political issues, technology), and (f) reform recommendations.

1.8 Limitation of the Study

This study acknowledges several limitations:

1. Data Availability: Access to confidential FIRS data (taxpayer-level data, audit results, refund processing times) may be restricted. The study will rely on published FIRS annual reports, budget documents, and other publicly available data.
2. Reliability of Published Data: FIRS data on registration, filing, and revenue may be incomplete or subject to revisions. The study will cross-check data from multiple sources (FIRS, CBN, NBS, IMF, World Bank).
3. VAT Gap Estimation: Estimating the VAT gap (difference between potential and actual revenue) requires assumptions about consumption, compliance, and the informal economy. Different estimation methods may produce different results.
4. Compliance Measurement: Measuring compliance levels (registration, filing, remittance) is challenging because the total population of eligible businesses is unknown (especially in the informal sector). The study will use estimates based on business registration data and surveys.
5. Attribution of Revenue Growth: It may be difficult to attribute changes in VAT revenue to specific factors (rate increase, economic growth, improved compliance, inflation). The study will use statistical analysis (regression) to isolate effects.
6. Limited International Comparison: While the study will reference international best practices, detailed comparison with other countries is limited by time and data availability.
7. Qualitative Data Limitations: Interviews with FIRS officials, tax practitioners, and taxpayers may be subject to bias (social desirability, recall). The study will triangulate qualitative data with documentary evidence.
8. Political Sensitivity: VAT revenue distribution and the constitutionality of FIRS administration are politically sensitive topics. Respondents may be reluctant to discuss these issues openly.

Despite these limitations, the study aims to provide robust, meaningful insights into the appraisal of Value Added Tax law and administration in Nigeria.

1.9 Operational Definition of Terms

Value Added Tax (VAT) : A consumption tax levied on the value added to goods and services at each stage of production and distribution, ultimately borne by the final consumer. In Nigeria, the standard VAT rate is 7.5%.

VAT Act: The Value Added Tax Act No. 102 of 1993, as amended, which provides the legal framework for VAT in Nigeria.

Finance Act: Annual legislation (Finance Act 2019, 2020, 2021) amending various tax laws, including the VAT Act, to update rates, expand the tax base, and enhance administration.

Output VAT: VAT charged by a registered business on its taxable supplies (sales) to customers.

Input VAT: VAT paid by a registered business on its taxable purchases (inputs) from suppliers.

VAT Liability: Output VAT minus Input VAT. If positive, the business remits the difference to FIRS. If negative (excess input VAT), the business may carry forward or claim a refund.

Input-Output Mechanism: The system that allows businesses to deduct input VAT from output VAT, ensuring that VAT is levied only on value added, not on total sales.

Exempt Supply: A supply that is not subject to VAT. No output VAT is charged, and input VAT cannot be deducted (no input VAT recovery). Examples: basic food items, medical and pharmaceutical products, educational services.

Zero-Rated Supply: A supply that is subject to VAT at 0% rate. Output VAT is charged at 0%, but input VAT can be deducted (input VAT recovery). Examples: non-oil exports, goods for use in EPZs.

Standard-Rated Supply: A supply subject to VAT at the standard rate (7.5% in Nigeria).

VAT Registration: The process by which a business with annual turnover above the threshold (N25 million) registers with FIRS to collect and remit VAT.

VAT Return: A periodic (monthly) return filed by a registered business reporting output VAT, input VAT, and VAT liability/refund.

VAT Remittance: The payment by a registered business to FIRS of positive VAT liability (output VAT minus input VAT).

VAT Refund: The payment by FIRS to a registered business of excess input VAT (input VAT exceeding output VAT), typically for exporters and businesses with zero-rated supplies.

VAT Audit: An examination by FIRS of a taxpayer’s records to verify the accuracy of VAT returns and compliance with the VAT Act.

VAT Fraud: Intentional deception to evade VAT, including issuing fictitious VAT invoices, under-declaring output VAT, over-declaring input VAT, and missing trader fraud (carousel fraud).

VAT Gap: The difference between potential VAT revenue (what would be collected if all businesses complied fully) and actual VAT revenue collected. The VAT gap is an indicator of non-compliance and weak administration.

Cost of Collection: FIRS administrative costs as a percentage of VAT revenue collected. Lower percentages indicate more efficient administration.

Federation Account: The central account into which all federally collected revenues (including VAT) are paid, before distribution to federal, state, and local governments.

FAAC (Federation Account Allocation Committee) : The committee that determines the distribution of federally collected revenues (including VAT) among federal, state, and local governments based on a statutory formula.

Federal Inland Revenue Service (FIRS) : The federal agency responsible for assessing, collecting, and accounting for federal taxes, including VAT.

Integrated Tax Administration System (ITAS) : The automated system used by FIRS for taxpayer registration, filing, payment, and reporting.

Electronic VAT (e-VAT) : The online platform for VAT registration, return filing, and payment.

Missing Trader Fraud (Carousel Fraud) : A complex VAT fraud scheme where goods are imported VAT-free, sold with VAT, the seller disappears without remitting VAT, and the goods are re-exported and re-imported (carousel).

VAT Compliance: The extent to which eligible businesses register for VAT, file returns on time, remit collected VAT, and maintain accurate records.

VAT Evasion: The illegal non-payment or under-payment of VAT by businesses, through fraud, misrepresentation, or concealment.

VAT Avoidance: The legal arrangement of transactions to minimise VAT liability (distinct from evasion, which is illegal).

Regressivity: The characteristic of a tax that takes a larger percentage of income from low-income households than from high-income households. VAT is generally regressive unless exemptions for basic goods are provided.

Cascading: Tax-on-tax, where a tax is levied on a tax (e.g., a sales tax on a price that already includes a sales tax). VAT avoids cascading through the input-output mechanism.

Place of Supply Rules: Rules determining where a supply of goods or services is deemed to occur for VAT purposes, important for cross-border transactions.

Reverse Charge Mechanism: A VAT mechanism where the buyer (rather than the seller) accounts for VAT on a supply, used for certain cross-border services and to combat fraud.

VAT Grouping: A provision allowing related companies to be treated as a single taxable person for VAT purposes, simplifying administration.

CHAPTER TWO: REVIEW OF RELATED LITERATURE

2.1 Introduction

This chapter reviews the literature relevant to the appraisal of Value Added Tax (VAT) law and administration in Nigeria. The review covers conceptual framework, including the definition and concept of VAT, types of VAT, VATable goods and services, exempted goods and services, Nigerian tax laws, VAT legal framework, scope of imposition, VAT rate, taxable person registration for VAT, rendering of account, computation of tax due, VAT on export, distribution of VAT proceeds, and recovery. The chapter provides the theoretical and legal foundation for understanding VAT law and administration in Nigeria.

2.1.1 Conceptual Framework

A conceptual framework is a structural representation of the key concepts or variables in a study and the hypothesized relationships among them. In this study, the conceptual framework is built around two primary constructs: VAT Law and Administration (the independent variable) and VAT Performance (the dependent variable). The framework posits that the effectiveness of VAT law and administration affects VAT performance outcomes: revenue generation, compliance levels, cost of collection, VAT gap, taxpayer satisfaction, and economic efficiency. The framework also identifies moderating variables (economic conditions, taxpayer behaviour, political environment, technology) that influence the relationship (Miles, Huberman, and Saldaña, 2020).

2.1.2 Value Added Tax (VAT)

Value Added Tax (VAT) is a consumption tax levied on the value added to goods and services at each stage of the production and distribution chain. Unlike a sales tax, which is levied only at the final point of sale to the consumer, VAT is collected at every stage of production and distribution, but businesses are entitled to deduct the VAT they have paid on their inputs (input VAT) from the VAT they charge on their outputs (output VAT). This mechanism ensures that VAT is ultimately borne by the final consumer, and businesses act as collectors on behalf of the government. VAT is a broad-based tax, typically covering most goods and services, though many countries exempt certain categories (e.g., basic food items, education, healthcare, financial services) and zero-rate others (e.g., exports) (Bird and Gendron, 2018; Tait, 2019).

VAT was first introduced in France in 1954 and has since been adopted by over 160 countries worldwide, including all OECD countries and most developing countries. VAT is preferred over sales tax because it avoids “cascading” (tax on tax) and is neutral with respect to production methods (tax does not favour capital-intensive over labour-intensive production). VAT is also difficult to evade because the input-output mechanism creates a paper trail. However, VAT is regressive (disproportionately affects low-income households) unless exemptions for basic goods are provided (Bird and Gendron, 2018).

2.1.3 Types of Value Added Tax (VAT)

There are three main types of VAT based on how input VAT is treated and how the tax base is calculated:

Gross Product Type (Income Type) : Under the gross product type, investment goods (capital goods, machinery) are not deductible; VAT is levied on the full sales price, and input VAT on capital goods is not recoverable. This type is rare in modern VAT systems because it discourages investment and distorts production decisions. It is used in some developing countries as a transitional measure.

Income Type: Under the income type, depreciation on capital goods is deductible over the useful life of the asset. This type is complex to administer because it requires tracking depreciation schedules for VAT purposes. It is rarely used.

Consumption Type: Under the consumption type (the most common type), input VAT on all business purchases, including capital goods, is fully deductible in the period of purchase (immediate deduction). This ensures that VAT is levied only on consumption (final consumer goods), not on investment. The consumption type is neutral with respect to investment decisions and is used in all modern VAT systems, including Nigeria (Tait, 2019; Bird and Gendron, 2018).

Nigeria operates a consumption type VAT, where registered businesses can deduct input VAT on all business purchases, including capital goods, in the period of purchase.

2.1.4 VATable Goods and Services

VATable goods and services are those that are subject to VAT at the standard rate (7.5% in Nigeria). The VAT Act lists taxable goods and services, but the list is not exhaustive; the general principle is that all goods and services are taxable unless specifically exempted or zero-rated. VATable goods and services in Nigeria include:

VATable Goods:

• All manufactured goods (food and beverages, except basic food items)
• Building materials
• Furniture and fixtures
• Electronics and electrical appliances
• Vehicles and spare parts
• Clothing and textiles (except traditional clothes)
• Cosmetics and toiletries
• Household goods
• Books and stationery (except educational books)
• Pharmaceutical products (except those on the exempt list)
• Agricultural inputs (except fertilizers)
• Petroleum products (except cooking gas)
• Cement and other building materials
• Industrial machinery and equipment
• Packaging materials (FIRS, 2020)

VATable Services:

• Professional services (legal, accounting, consulting, engineering, architecture)
• Telecommunication services (voice, data, internet)
• Banking and financial services (except those exempted)
• Insurance services
• Hotel and hospitality services
• Event management and catering
• Transportation and logistics (except certain passenger transport)
• Real estate services (agency, property management)
• Advertising and marketing services
• Information technology services
• Maintenance and repair services
• Security services
• Cleaning and waste management services
• Educational services (except primary and secondary education)
• Healthcare services (except certain basic healthcare) (FIRS, 2020)

2.1.5 Exempted Goods and Services

Exempt goods and services are those that are not subject to VAT. No output VAT is charged on exempt supplies, and businesses cannot deduct input VAT related to exempt supplies (input VAT recovery is denied). Exemption is used for goods and services that are considered essential for low-income households or for social policy reasons. In Nigeria, exempt goods and services include:

Exempt Goods:

• Basic food items: unprocessed agricultural products, bread, milk, eggs, fish (fresh and frozen), meat, poultry, fruits, vegetables, cereals (rice, maize, millet, sorghum), yam, cassava, plantain, beans, and other staples
• Medical and pharmaceutical products: drugs, vaccines, medical equipment, hospital supplies
• Educational materials: books, exercise books, stationery for primary and secondary education
• Newspapers and magazines
• Fertilizers and agricultural inputs
• Baby products (diapers, formula, baby food)
• Cooking gas (LPG)
• Renewable energy products (solar panels, inverters, batteries)
• Aircraft and aircraft spare parts (FIRS, 2020; VAT Act, 1993 as amended)

Exempt Services:

• Basic education (primary and secondary school education)
• Basic healthcare services (primary healthcare, maternal and child health)
• Services of community banks and mortgage institutions
• Services of religious and charitable organisations
• Services of trade unions and professional associations (membership fees)
• Postal services (basic mail)
• Public transportation (by road, rail, water) for passengers
• Funeral and burial services (FIRS, 2020)

Significance of Exemption: Exemption reduces the tax burden on low-income households, but it also introduces complexity (businesses must distinguish between exempt and taxable supplies) and creates inefficiencies (input VAT on exempt supplies is not recoverable, leading to cascading). Exemption also creates an incentive for businesses to self-supply (produce exempt goods in-house) to avoid unrecovered input VAT (Bird and Gendron, 2018).

2.1.6 Nigerian Tax Laws

The Nigerian tax system is governed by several laws, including:

Companies Income Tax Act (CITA) Cap C21 LFN 2004 (as amended) : Governs taxation of corporate income.

Personal Income Tax Act (PITA) Cap P8 LFN 2004 (as amended) : Governs taxation of individuals, including employees and self-employed persons.

The Finance Acts have significantly amended the VAT Act, including increasing the VAT rate from 5% to 7.5% (Finance Act 2019), expanding the list of exempt goods and services, and introducing new compliance requirements (FIRS, 2021).

2.1.7 VAT Legal Framework

The legal framework for VAT in Nigeria consists of:

Value Added Tax Act (VATA) Cap V1 LFN 2004: The primary legislation governing VAT. The VATA was originally enacted as Decree No. 102 of 1993 and has been amended several times.

VAT (Amendment) Act 2007: Introduced changes to the VAT distribution formula and expanded the list of exempt goods.

VAT (Amendment) Act 2015: Introduced the requirement for non-resident companies (digital service providers) to register for VAT.

Finance Act 2019: Increased VAT rate from 5% to 7.5% (effective February 1, 2020); expanded the list of exempt goods and services; introduced electronic invoicing and real-time reporting requirements; enhanced penalties for non-compliance.

Finance Act 2020: Clarified VAT treatment of e-commerce and digital services; introduced reverse charge mechanism for cross-border services; expanded VAT registration threshold.

Finance Act 2021: Introduced VAT on non-oil exports (zero-rated); clarified VAT treatment of renewable energy products (exempt); enhanced refund processing provisions.

Finance Act 2022 and 2023: Further amendments to VAT compliance, enforcement, and refund procedures (FIRS, 2020; FIRS, 2021).

FIRS Regulations and Guidelines: The FIRS issues regulations, guidelines, and circulars to operationalise the VAT Act. These include:

• VAT Registration Guidelines
• VAT Return Filing Guidelines
• VAT Audit Guidelines
• VAT Refund Guidelines
• VAT e-Invoicing Guidelines
• VAT Guidelines for Non-Resident Companies (Digital Services)

Judicial Precedents: Court decisions interpreting the VAT Act provide guidance on VAT treatment of specific transactions.

2.1.8 Scope of Imposition

The scope of VAT imposition defines which transactions are subject to VAT. Under the VAT Act, VAT is imposed on:

Supply of Goods: The transfer of ownership of goods (including sale, exchange, barter, hire purchase, and lease) in Nigeria. Goods include all tangible movable property (machinery, equipment, vehicles, furniture, electronics, raw materials, finished goods, etc.) and certain intangible property (copyright, patents, trademarks, etc.) as defined by law.

Supply of Services: The performance of any service for consideration (fee, payment, commission, reward) in Nigeria. Services include professional services, telecommunications, banking, insurance, transportation, hospitality, entertainment, and others.

Importation of Goods: Goods brought into Nigeria from abroad are subject to VAT at the point of importation (paid to Nigeria Customs Service), in addition to import duties. Import VAT is calculated on the customs value plus import duty.

Importation of Services: Services provided by a non-resident to a Nigerian resident are subject to VAT under the reverse charge mechanism (the Nigerian resident self-accounts for VAT). This includes digital services (streaming, software, cloud computing, online advertising) provided by non-resident companies (FIRS, 2020).

Excluded from the scope of VAT are:

• Goods and services exempted under the VAT Act (see section 2.1.5)
• Transactions below the registration threshold (businesses with annual turnover below N25 million are not required to register for VAT, but may voluntarily register)
• Supplies by unregistered persons (no VAT is charged, but unregistered persons cannot deduct input VAT)

2.1.9 VAT Rate

The standard VAT rate in Nigeria is 7.5% , effective from February 1, 2020 (increased from 5% under the Finance Act 2019). The rate applies to all taxable supplies (goods and services) unless specifically zero-rated or exempt.

Zero Rate (0%) : Certain goods and services are subject to VAT at 0% (zero-rated). Unlike exempt supplies, zero-rated supplies allow businesses to deduct input VAT. Zero-rated supplies include:

• Non-oil exports (goods and services exported from Nigeria)
• Goods and services for use in Export Processing Zones (EPZs)
• Goods and services purchased by diplomats and international organisations
• Goods and services for use in humanitarian donor-funded projects
• Aircraft and aircraft spare parts
• Renewable energy products (solar panels, wind turbines) (Finance Act 2021)

Significance of Zero Rating: Zero rating promotes exports (exports are free of VAT to be competitive internationally) and reduces the cost of essential investment goods (aircraft, renewable energy). Zero rating is also used for administrative convenience (e.g., to avoid refund claims for VAT paid on exports) (Tait, 2019).

Difference Between Zero Rate and Exemption:

Feature	Zero Rate (0%)	Exemption
Output VAT	0% (no VAT charged)	No VAT charged
Input VAT recovery	Yes (deductible)	No (not deductible)
Effect on business	Refund (if input VAT > output VAT)	Input VAT becomes cost
Effect on competition	Exports competitive	May disadvantage local producers
Complexity	Moderate	High (determining exempt vs. taxable)

2.1.10 Taxable Person Registration for VAT

A taxable person is any individual, company, partnership, government entity, or other entity that makes taxable supplies of goods or services in Nigeria. Under the VAT Act, a taxable person with annual turnover exceeding the registration threshold is required to register for VAT. The registration threshold is N25 million (annual turnover). Businesses with turnover below the threshold are not required to register but may voluntarily register.

Registration Process:

1. Application: The taxable person completes a VAT registration application form (Form 001) online via the FIRS Integrated Tax Administration System (ITAS) or at a FIRS tax office.
2. Documentation: Submit required documents: (a) Certificate of Incorporation (for companies) or Business Registration (for sole proprietors), (b) Memorandum and Articles of Association, (c) Tax Identification Number (TIN), (d) Proof of business address (utility bill, tenancy agreement), (e) Bank statement, (f) Identification documents of directors/proprietors.
3. Verification: FIRS verifies the application and may conduct a physical inspection of the business premises.
4. Issuance of VAT Certificate: Upon approval, FIRS issues a VAT Registration Certificate (with the business’s VAT number) and a stamp for issuing VAT invoices.
5. Time Limit: Registration must be completed within six months of the commencement of business or within six months of exceeding the registration threshold (FIRS, 2020).

Obligations of Registered Taxable Persons:

• Charge VAT on all taxable supplies (output VAT) at the standard rate (7.5%)
• Issue VAT invoices for all taxable supplies (must show VAT number, amount of VAT charged)
• Keep accurate records of all supplies (purchases and sales)
• File VAT returns (Form 002) monthly (by the 21st day of the following month)
• Remit positive VAT liability (output VAT minus input VAT) to FIRS by the 21st of the following month
• Retain records for at least six years
• Cooperate with FIRS audits and investigations

Penalties for Non-Registration and Non-Compliance:

• Late registration: N50,000 penalty (first month) and N25,000 for each subsequent month
• Late filing of return: N50,000 for each month of default
• Late remittance of VAT: 5% penalty plus interest at the prevailing CBN monetary policy rate
• Failure to issue VAT invoice: N50,000 penalty
• Willful evasion: fine and/or imprisonment (FIRS, 2020)

2.1.11 Rendering of Account

Rendering of account refers to the filing of VAT returns by registered taxable persons. The VAT return (Form 002) is the document through which the taxpayer reports output VAT, input VAT, and VAT liability/refund for a given period.

Content of VAT Return:

• Taxpayer identification (name, VAT number, TIN)
• Period covered (month)
• Total taxable supplies (gross sales) for the period
• Output VAT charged (taxable supplies × 7.5%)
• Total taxable purchases for the period
• Input VAT paid (taxable purchases × 7.5%)
• Input VAT adjustments (for exempt supplies, capital goods, etc.)
• Net VAT liability (output VAT – input VAT)
• VAT remitted (if liability positive) or excess input VAT carried forward (if input VAT > output VAT)
• Declaration by taxpayer (signed by director/proprietor and accountant)

Filing Deadline: VAT returns must be filed by the 21st day of the month following the end of the tax month. For example, the return for January must be filed by February 21.

Filing Methods:

• Online via the FIRS e-VAT portal (electronic filing)
• Manual filing at FIRS tax offices (paper forms)
• Through approved tax agents/consultants

Filing Frequency: Monthly (12 returns per year). Large taxpayers may be required to file monthly; small taxpayers may file quarterly in some jurisdictions, but in Nigeria, monthly filing is required for all registered taxpayers (FIRS, 2020).

Consequences of Late Filing:

• Penalty of N50,000 for each month of default
• Interest on any outstanding VAT liability (at CBN monetary policy rate)
• Legal action (prosecution) for persistent default

2.1.12 Computation of Tax Due

The computation of VAT due (VAT liability) is based on the formula:

VAT Liability = Output VAT – Input VAT (Recoverable)

Output VAT = Total taxable supplies × VAT rate (7.5%)

Input VAT (Recoverable) = VAT paid on taxable purchases used for making taxable supplies (including zero-rated supplies). Input VAT on purchases used for making exempt supplies is not recoverable (blocked input VAT). Input VAT on purchases used for both taxable and exempt supplies must be apportioned (using an approved allocation method).

Example of VAT Computation:

Assume a manufacturing company has:

• Taxable sales: N10,000,000 (output VAT = N10,000,000 × 7.5% = N750,000)
• Taxable purchases (raw materials, packaging): N6,000,000 (input VAT = N6,000,000 × 7.5% = N450,000)
• Capital goods purchases (machinery): N2,000,000 (input VAT = N2,000,000 × 7.5% = N150,000)
• Exempt purchases (basic food for staff canteen): N500,000 (input VAT = N500,000 × 7.5% = N37,500 – not recoverable)

Recoverable Input VAT = N450,000 + N150,000 = N600,000

Net VAT Liability = N750,000 – N600,000 = N150,000 (positive, payable to FIRS)

If input VAT exceeds output VAT (e.g., for exporters with zero-rated supplies), the excess is treated as:

Excess Input VAT = Input VAT – Output VAT

Treatment of Excess Input VAT:

• Carry Forward: The excess input VAT can be carried forward to subsequent months to offset future output VAT. This is the default treatment in Nigeria.
• Refund: Taxpayers may apply for a refund of excess input VAT in certain circumstances: (a) exports (zero-rated supplies), (b) capital goods, (c) cessation of business, (d) where the excess input VAT is due to a VAT rate reduction. Refund applications are subject to FIRS verification and audit (FIRS, 2020).

VAT Accounting Methods:

Invoice Method: VAT is accounted for when an invoice is issued (or when a payment is received, whichever is earlier). This is the standard method in Nigeria.

Cash (Receipts) Method: VAT is accounted for when payment is received (not when invoice is issued). This method is permitted for small businesses (turnover below N25 million) to ease cash flow.

Fractional Method: For mixed supplies (taxable and exempt), VAT is apportioned based on the ratio of taxable supplies to total supplies.

2.1.13 VAT on Export

Exports of goods and services from Nigeria are zero-rated (0% VAT), not exempt. Zero rating means:

• No output VAT is charged on exports
• Input VAT incurred on goods and services used to produce exports is recoverable (deductible)
• Exporters may claim VAT refunds for excess input VAT (input VAT > output VAT)

Rationale for Zero-Rated Exports: Exported goods compete in international markets. If VAT were charged on exports, Nigerian exports would be more expensive than competitors’ products. Zero rating is the international standard for VAT treatment of exports (Bird and Gendron, 2018).

Documentation for Zero-Rated Exports:

• Bill of lading or airway bill (proof of export)
• Customs export declaration (Form M, Form NXP)
• Commercial invoice
• Evidence of receipt of foreign currency (inflow of export proceeds)
• VAT refund application (Form 002 with supporting documents)

VAT Refund for Exporters:

• Exporters may apply for refund of excess input VAT (input VAT on inputs used to produce exports)
• Refund applications must be filed with supporting documents
• FIRS has 90 days to process refund applications (statutory limit)
• In practice, refund processing often takes longer (6-24 months) due to verification requirements and funding constraints (FIRS, 2020)

Penalties for False Export Claims: Claiming VAT refunds on fictitious exports (ghost exports) is a criminal offence. Penalties include repayment of refunded VAT, fines (100-200% of refund claimed), and imprisonment.

2.1.14 Distribution of VAT Proceeds

VAT proceeds (revenue) are distributed to the three tiers of government (federal, state, local) based on a statutory formula. The distribution is managed by the Federation Account Allocation Committee (FAAC).

Distribution Formula (Section 40 of the VAT Act, as amended) :

• Federal Government: 15% of VAT proceeds
• State Governments: 50% of VAT proceeds
• Local Government Councils: 35% of VAT proceeds

Additional Allocations:

• Collection Cost: FIRS retains 4% of VAT proceeds as cost of collection (administrative expenses)
• State Distribution Criteria: The 50% allocated to state governments is distributed as follows:
  • Equality: 20% distributed equally among all states (each state receives the same amount)
  • Population: 50% distributed based on population (states with larger populations receive more)
  • Internally Generated Revenue (IGR) : 30% distributed based on IGR (states with higher IGR receive more)

Local Government Distribution: The 35% allocated to local government councils is distributed based on similar criteria (equality, population, IGR) determined by each state.

Evolution of the Distribution Formula:

• Original VAT Act (1993): Federal 20%, State 50%, Local 30%
• VAT (Amendment) Act 2007: Federal 15%, State 50%, Local 35% (current formula)
• Finance Act 2021: No change to distribution formula

Controversies:

• States with high economic activity (Lagos, Rivers, Kano) argue that the distribution formula does not adequately reflect their contribution to VAT generation. They generate more VAT but receive a smaller share relative to their contribution.
• Some states have challenged the constitutionality of the FIRS administering VAT, arguing that VAT is a state tax (consumption tax). The Supreme Court ruled on this issue in 2022, affirming that VAT is a federal tax, but political tensions remain.
• The distribution formula has been criticised for encouraging states to rely on federal VAT allocations rather than developing their own IGR (Adebayo and Oyedokun, 2020).

2.1.15 Recovery

Recovery in the context of VAT refers to the deduction of input VAT from output VAT (input VAT recovery). Recovery is the mechanism that ensures VAT is levied only on value added, not on total sales.

Conditions for Input VAT Recovery:

• The taxpayer must be a registered taxable person.
• The input VAT must be on goods or services used for making taxable supplies (including zero-rated supplies).
• The taxpayer must hold a valid VAT invoice (issued by a registered supplier) with the supplier’s VAT number.
• The goods or services must have been delivered or performed (not just ordered).
• The input VAT must not be on exempt supplies or on non-business expenses.

Blocked Input VAT (Non-Recoverable) :

• Input VAT on goods and services used for making exempt supplies
• Input VAT on entertainment expenses (unless specifically approved)
• Input VAT on personal expenses of directors and employees
• Input VAT on goods lost or stolen
• Input VAT on goods not delivered (ghost purchases)
• Input VAT on VAT penalties and interest
• Input VAT on membership fees (unless trade-related) (FIRS, 2020)

Time Limit for Recovery:

• Input VAT must be claimed in the VAT return for the period in which the VAT invoice is dated (or the period in which the goods are received/services performed)
• Input VAT claimed in a later period (late claim) may be disallowed unless approved by FIRS

Apportionment of Input VAT (Mixed Supplies) :
Where a taxpayer makes both taxable and exempt supplies, input VAT must be apportioned:

• Direct Attribution: Input VAT directly attributable to taxable supplies is fully recoverable
• Direct Attribution: Input VAT directly attributable to exempt supplies is not recoverable (blocked)
• Residual Input VAT: Input VAT not directly attributable to either (e.g., administrative overhead) is apportioned based on the ratio of taxable supplies to total supplies

Apportionment Formula:
Recoverable Residual Input VAT = Residual Input VAT × (Taxable Supplies ÷ Total Supplies)

VAT Recovery in Special Cases:

Capital Goods: Input VAT on capital goods (machinery, equipment, vehicles, buildings) is fully recoverable in the period of purchase (consumption type VAT). Some countries spread recovery over the useful life of the asset, but Nigeria permits immediate deduction.

Bad Debts: If a customer fails to pay for goods or services (bad debt), the taxpayer may recover the output VAT previously remitted on that bad debt. The recovery must be claimed within a specified time (e.g., six months after the debt becomes bad).

VAT Refunds: Where input VAT exceeds output VAT (excess input VAT), the taxpayer may carry forward the excess to subsequent periods or apply for a refund (see section 2.1.13). Refund applications are subject to verification (FIRS, 2020).
