In many ways administrators in the year 2000 are doing exactly what they did in the year 1970.Only the means and medium of doing so have changed. They still administer revenue laws that trail social and scientific developments by a long margin and are often nightmarish in their complexity. They still devote more than 60% of our resources to processing information received from taxpayers in the form of tax returns. They process the information received relatively inefficiently. The taxpayer provides the data in a paper return, they re-transcribe that information onto our various information systems, and they process that information in batch mode, and that generates further paper that are send to the taxpayer. They still rely on information from our taxpaying clientele which is outdated and often unreliable before we even begin to process it. A significant proportion of our resources provides personal and person-to-person services to our taxpaying client, and still work from centralised offices and locations.

They still support a number of economic and social paradoxes, and rely on increasingly outdated accounting conventions and often-artificial geographical and jurisdictional limitations. Natural resources for example attract no value on the conventional company balance sheet, but most governments are attempting to conserve same. Most income taxes reward expenditure (related to the gaining of income) and discourage frugality and saving. Our tax regimes encourage personal, corporate and national debt, whilst our Treasuries bemoan the lack of national savings and funds.

They encourage the artifice of trans-national corporate entities, and yet fail to associate those entities with actual productive, economic and trading activities in their supposed countries (often tax havens) of domicile.

They are still coming to grips with phenomena like the multi-national corporation, profit shifting, corporate tax minimisation, tax competition and tax havens. And what had previously been the sole purvey of large corporations is now well within the capabilities of small to medium enterprises thanks to computers and the Internet. They allow many entities to hide behind legal and professional privilege, or an easily obfuscated trans-jurisdictional corporate structure. They are, however, slowly coming to grips with these issues.


The major compliance problems that face a society are still, broadly speaking, identity, evidence and jurisdiction … although we are coming to grips with these questions in a multitude of different ways.

Though the information technology revolution is redefining our traditional focuses and boundaries it also offers a number of new threats to the revenue that were collected. At present we seem to be applying old business models, forms and methods to the new environment, but this will no doubt change as the system refine their appreciation of electronic commerce, enterprise application integration and real-time automation, and integrate  IT systems better.

In-spite of these, the tax system in Nigeria is crippled with in-efficiency, in policy and personnel, and achieves less effectiveness with high rate of evasion despite myriad of reforms by the government. Thus this research project searches deeply into the causes of the problem and how to revamp an ICT base tax administration in Nigeria as an expedient tax base and sustainable economic development.


These include the aim of which this research work is being carried out and it includes the following:

  1. To examine the present state of  tax administration in Lagos
  2. To determine the degree and area of improvement observed after the introduction of ICT base tax administration.

iii.  To determine if the ICT base tax system is the cause of reduction in tax aviation noticed in Lagos state.

  1. To know how enumeration of tax personnel affects the ICT base tax administration.


  1. Is the degree of improvement observed in Lagos state recent tax generation due to the introduction of ICT base tax administration?

2        Is the ICT base tax system in Lagos state the cause of reduction in tax aviation noticed in Lagos state?

3        Does enumeration of tax personnel affect the ICT base tax administration?


H0:   ICT base tax administration does not have significant effect tax generation.

H1:   ICT base tax administration does have significant effect tax generation.

H0:   ICT base tax system in Lagos state is not the cause of reduction in tax aviation noticed in Lagos state.

H1:   ICT base tax system in Lagos state is the cause of reduction in tax aviation noticed in Lagos state.

H0:   Enumeration of tax personnel does not affect the ICT base tax administration.

H1:  Enumeration of tax personnel does affect the ICT base tax administration?


Reform of the revenue administration may be needed to enable it to keep up with the increasing sophistication of business activity and tax evasion schemes. With globalization, goods and services are produced by taxable entities in multiple countries. This presents vast opportunities for manipulating transactions to reduce the tax burden. The existence of tax havens, electronic financial transactions and the increasing use of the internet in commerce pose major challenges in enforcing the tax laws. Even, run-of-the-mill domestic taxpayers are increasingly using information technology for running their businesses and for accounting. Without a matching increase in the professional and technological capacity of the revenue administration, its chances of monitoring taxable activity and countering tax evasion are seriously reduced. Thus a study of the effect that ICT base systems have had on tax administration in the study area will give us a better view of its prospect to the nation at large.
