This research study examines the Effect of Information Technology on the Efficiency of Tax Administration in Nigeria, a case Study of Enugu State Board of Internal Revenue. Its main objective is to find out whether the application of Information Technology increases efficiency on tax administration. For the purpose of this study, the researcher adopted the method of survey Research Design. Data used in this research were gotten from both primary and secondary sources including questionnaires and textbooks respectively. These data were analyzed and presented in tables. Three (3) hypotheses were formulated and tested using the Analysis of variance(ANOVA) method. The findings of this research tend to show that effective tax administration resulting from the application of Information Technology leads to an increase in tax base as more potential taxpayers are drawn into the tax net when there is a conducive environment. It is recommended in this work that enlightenment campaign be made available for the masses and also adequate training for the tax officials on the use of modern technology

Chapter One


1.1 Background of the Study

Taxation is one of the oldest and major sources of government revenue. The history of taxation in Nigeria dates back to the pre-colonial era. During this period, there were different systems of taxation existing in the forms of compulsory services, contribution of goods, money, labour and the likes, among the various kingdoms and ethnic groups and tribes controlled by the Obas, Emirs etc., in order to sustain the Monarch and also for community development (ICAN,2010)

Taxation, as we know it today, was first introduced in Nigeria in 1904 by the late Lord Lugard, when community tax became operative in the Northern Nigeria. He later made changes which culminated in the Native Revenue Ordinance of 1917. An amending ordinance that extended the provisions of the 1917 ordinance to Southern Nigeria was passed in 1918. The first ordinance applied to Abeokuta in Western Nigeria and to Benin-city in Mid-Western and in 1928, it was extended to Eastern Nigeria.

Taxation in Nigeria, in a modern sense, however, only began in 1940. A more progressive income tax Ordinance No.29 of 1943 Cap92, under which Europeans all over the country and Africans resident in Lagos were assessed, came into operation on the 1st of April, 1943.

The Commissioner, appointed by the Governor-General by notice in the Gazette (now referred to as the Federal Republic of Nigeria Gazette), was responsible for the administration of the ordinance. By the 1st Schedule, Ordinance 39/58, it was the Federal Board of Inland Revenue that took the place of the Commissioner (Ola, 1974).

In recent times, tax administration in Nigeria is vested in various tax authorities depending on the type of tax under consideration. Broadly, there are three (3) tax authorities, namely;

  1. Federal Inland Revenue Service Board
  2. State Internal Revenue Service Board
  3. The Local Government Authorities

However, the organs of the Nigerian Tax Administration are listed below;

  1. Federal Inland Revenue Service Board
  2. State Internal Revenue Service Board
  3. Joint Tax Board
  4. Local Government Revenue Committee
  5. Joint State Revenue Committee. (ICAN, 2010)

The enabling laws in respect of each type of tax will normally contain a provision as to the body charged with the administration of the tax. For this purpose, the various enabling tax laws are as follows;

  1. Company Income Tax Act, Cap C21, LFN 2004, as amended, which imposes tax on the incomes of companies other than corporation soles and companies engaged in petroleum operations Upstream operations)
  2. Petroleum Profits Tax Act, Cap P13 LFN 2004, which imposes tax on the profits of companies, engaged in petroleum operations.
  3. Education Tax Act, Cap E4 LFN 2004, which imposes Education tax on the assessable profits of companies registered in Nigeria.
  4. Personal Income Tax Act, Cap P8 LFN 2004, as amended, which imposes tax on incomes of individuals and corporation soles.
  5. Value Added Tax Act, Cap V1 LFN 2004, as amended, which imposes tax on the supply of goods and services (except those specifically exempted or zero-rated), made by incorporated companies and other business organizations.
  6. Stamp Duties Act, Cap S8 LFN 2004, which charges duties on specified instruments listed in the Act.
  7. Capital Gains Tax Act, Cap C1 LFN 2004, which imposes tax on capital gains arising from the disposal of chargeable assets (ICAN, 2006)

According to Alhaji Kabir M. Mashi, a core success factor for any system is its position on administrative issues. Presently, the tax administration in Nigeria, Enugu state to be precise, has been riddled with various limiting factors such as;

  1. Weak administrative facilities/ administrative lapses which could result in situations such as tax evasion and tax avoidance.
  2. Corruption and mismanagement on the part of the tax officials.
  3. The problem of funding the revenue collecting agencies which negatively impacts on efficiency and performance.
  4. Lack of adequate records from the informal sector of the economy.
  5. Inability to identify all taxable persons. (Bird, 1988).
  6. Lack of effective mechanism in place to prosecute cases of tax evasion.

The rapid growth and development of Enugu State led to an enhanced increase in population as well as an increasing number of companies. Tax planning and tax management have increasingly become complex activities due to growth in business and the subsequent expansion in scope of operations and fiscal size. Given the amount of data that needs to be analyzed in order to assess and compute tax liabilities, it has become imperative that both tax institutions and companies deploy appropriate computer programmes in order to enhance tax planning and administration.

The advent of Information Technology in this era has played a major role in enhancing economic and business activities of both the private and public institutions. While it has opened up opportunities that have gone undiscovered or neglected, it has saved many organizations millions of perpetual fraud through its applications. The application of Information Technology has become increasingly necessary in Nigeria’s tax administration as the use of Information Technology makes for fast, easy and accurate computation, storage and presentation/ retrieval of data/ records.

Certain computer programmes have been created to facilitate the computation of cumbersome data. Programmes such as Microsoft Excel (Electronic Spread Sheet), Microsoft Access (Database) are one of the most common examples. Other database programmes and accounting packages which allow for easy calculation and computation of an individual or a company’s tax liabilities include Peachtree Accounting, PeopleSoft System, SQL Database, QuickBooks, Management Information Processing System, Quikens etc.

Presently, the world has gradually become a global village and the nexus between Nigeria and the rest of the world is the use of Information Technology in, practically, every sector of the economy. Therefore, in order to improve on the efficiency of tax administration in Nigeria, it will be advisable to apply the use of Information Technology from the basics of tax collection to the final stage in Tax Administration.

1.2 Statement of the Problem

For many years, tax administration in Nigeria has been plagued with problems, most of which can be attributed to the lack of or inadequate application of Information Technology in tax administration.

In Enugu State, the tax institutions have not fully embraced the use of Information Technology for record keeping. According to BECANS Business Environment Report 1(15) (2007), there is evidence of a manually compiled database of tax payers. Manual Compilation involves the use of files/ folders for data storage. When records are stored in this manner over a long period of time, retrieval of such records can prove to be very difficult. Records stored in this manner can be very unreliable as these records are easily prone to manipulations.

Another major problem can be found in the method of tax collection. The tax officials are often aggressive as they use unorthodox methods in tax collection especially at the local government level.

Furthermore, the identification of taxable persons has proven to be a herculean task using the manual systems.

The thorough application of Information Technology in tax administration in Nigeria would be a welcome change in the system as this will greatly enhance the efficiency in tax administration in Enugu state in particular and Nigeria in general.

1.3 Objective of the Study

This research work is aimed at achieving certain objectives which are stated below:

  1. To determine if effective tax administration leads to an increase in tax base;
  2. To ascertain whether inefficiency in tax administration creates room for tax evasion;
  3. To find out whether the application of information technology increases efficiency in tax administration;
  4. To know whether poor remuneration of tax personnel affects the dispensation of taxation.

1.4 Research Questions

  1. Does effective tax administration lead to an increase in tax base?
  2. Does inefficiency in tax administration create an avenue for tax evasion?
  3. Does the application of Information technology increase efficiency in tax administration?
  4. Does poor remuneration of tax personnel affect the effective tax administration?

1.5 Research Hypotheses

Based on the objectives, the following researches were formulated:

Hypothesis One
  • H0- Effective tax administration does not lead to an increase in tax base.
  • H1- Effective tax administration lead to an increase in tax base. Hypothesis Two
Hypothesis Two
  • H0- Inefficiency in tax administration does not create and avenue for tax evasion.
  • H1- Inefficiency in tax administration create and avenue for tax evasion.
Hypothesis Three
  • H0- The application of information technology does not increase efficiency in tax administration.
  • H1- The application of information technology increase efficiency in tax administration.

1.6 Significance of the Study

It is hoped that this work will form a major catalyst to stimulate the initiation of a proper legislative process that will regulate tax administration in Nigeria, particularly in Enugu State.

Furthermore, effective implementation of information technology in tax administration will be of immense benefit to tax authorities. The use of information technology will invariably reduce work hours, enhance efficiency and reduce opportunities for corrupt practices in the system.

Finally, it is believed that the information generated from this research will enhance the tax payers awareness on tax issues like tax incentives and penalties for tax related offences such as tax evasion.

1.7 Scope and Limitation of the Study

As this research work is focused on the effect of information technology on the efficiency of tax administration in Nigeria, with particular reference to Enugu State, the scope of the study will be limited to the activities of Enugu State Board of Internal Revenue

In the course of carrying out this research work, certain limitations were encountered, they include the following:

  1. Lack of access to certain materials needed for the research.
  2. Lacks of co-operation from institutions as certain tax institutions were not forthcoming with their record
  3. Certain libraries did not have contemporary materials for the researcher to work with.

1.8 Operational Definition of Terms

Summary of the Findings, Conclusion and Recommendations

This is the final stage of the research work where all the contents are summarized, the findings are collected and recommendations are made to ameliorate the present state of tax structures in Nigeria. The conclusion drawn here is a function of the research findings and the analysis conducted

5.1 Summary of Findings

In the course of the research conducted, certain points were deduced from the responses. These points include;

  1. Effective tax administration leads to an increase in tax base as more potential taxpayers are drawn into the tax net when there is a conducive environment or situation for a taxpayer.
  2. Tax evasion can be reduced to the barest minimum if the administrative bodies are fully and promptly equipped with contemporary materials and equipment to carry out their duties and if they are duly authorized to penalize defaulters severely
  3. The application of information Technology is of the major key to facilitating the effectiveness and the efficiency of tax administration in any given society or Enugu state as a case study.
  4. When tax officials are adequately motivated due to better remuneration, only then can they exercise their duties with utmost diligence and perseverance.

5.2 Conclusion

Tax administration in Nigeria has been plagued with series of problems over the years. Problems such as poor remuneration of staff, that is tax officials can lead to inefficiency in tax duties being carried out. Other salient issues include manual compilation systems and discrepancies in tax law formulation.

These and other problems have resulted in reducing taxpayers compliance thereby creating an avenue for tax evasion.

The adoption of information technology has therefore been proven to alleviate the effect of inefficiency of tax administration in Nigeria.

5.3 Recommendation

It is worthy of note to recommend tat anal out inculcation of information technology in the daily activities of tax administration be adopted as this will radically transform out tax management system, giving the tax administration in Nigeria a complete overhaul. An efficient and effective tax administration with the use of modern technologies will not only guarantee an increase in revenue base for the government but also position the country properly to take full advantages offered by the minimal development.

Furthermore, the acceptance and full application of information technology in tax administration cannot be over-emphasized as the federal board of Inland Revenue (FBIR) has not over looked the importance and relevance of information Technology. According to the Ag. Executive Chairman of FBIR, Alhaji Kabir M. Mashi, the board has found a way to identify all taxable persons and monitor their compliance by issuing a number to all taxpayers known as unique tax identification Number (U-TIN) this is done in a manner so that no two persons can have the same number.

Therefore, for effective tax administration using information technology, the following actions are recommended;

  1. There should be periodic enlightenment campaign for the masses
  2. Adequate training of tax officials on the use of the modern technologies and equipping them with those modern systems to keep abreast of the Global travel.
  3. Adequate record keeping of the taxpayers information using modern technology
  4. Application of stiff penalties on tax evaders to serve as examples and ward off any attempt by the prospective tax evaders.
