Tax has been variously defined over the years. These definitions, when looked at as a whole gives a more comprehensive picture of the phenomenon as opposed to a single definition. According to the Oxford English Dictionary the word tax' refers to a compulsory contribution to the support of government levied on persons, property, income, commodities, transactions, etc, now at a fixed rate mostly proportionate to the amount on which the contribution is levied. While this serves in crude terms to tell us what a tax is, it is however deficient in the sense that it does not reveal the purpose of taxation. We however find more scholarly definitions in decided cases. For instance, in MATTHEWS v. CHICORY MARKETING BOARD it was held that a tax is:
"A compulsory exertion of money by a public authority for public purposes, or taxation is raising money for the purpose of government by means of contribution of individual persons."
In US v. BUTLER it was opined per Justice Roberts that:
"A tax in the general understanding of the term and as used in the Constitution signifies an exertion for the support of government. The word has never been thought to connote the expropriation of money from one group for the benefit of another."
Again in R v. BARGER the court held as follows:
"The primary meaning of taxation is raising money for the purposes of government by means of contributions from individual persons."
From these definitions, it is clear that a tax basically is a fund pooled from the members of a society for the public or governmental use.
Tax administration refers to the care and management of the phenomenon of taxation. It is the enforcement of the provisions of the relevant tax statutes in relation to taxpayers. In Nigeria, the administration of income tax, company tax including capital gains tax and petroleum profits tax is vested in the Federal Board of Inland Revenue. This body is empowered by the COMPANIES INCOME TAX ACT (CITA)1990, which provides in S 2(1) that:
"The due administration of this Act and the tax shall be under the care and management of the Board who may do all such things as may be deemed necessary for the assessment and collection of the tax and shall account for the amounts so collected in a manner to be prescribed by the Minister."
Earlier, the Act had established and guaranteed the continued existence of the Board (from the previous 1961 Act) by providing in S 1(1) that:
"There shall continue to be a board of which the official name shall be the Federal Board of Inland Revenue "
In addition to the Board, the CITA 1961 made provision for Scrutineer Committees to assist the Board in the discharge of its duties. The function of these Scrutineer Committees was to make recommendations in respect of assessment of profits of both individuals and limited companies to the Board. However, in practice the Committees were never used and so were abolished in the CITA 1990. But the PERSONAL INCOME TAX (PITA) makes provision in S 85 for a Joint Tax Board, whose function it was to advice the Federal Government in matters relating to tax. The Chairman of the Joint Tax Board was to also be the head of the Federal Board of Inland Revenue.
Essentially, there are three components or elements of taxation. These are levying, assessment and collection of taxes. Where these three are in operation, tax administration is effective and taxation fulfils its purposes. Our aim in this paper is to proceed with an analysis of all three components and then conclude by making proposals for the plugging of the loopholes in the administration of tax in the Nigerian context. It is our belief that these recommendations will also make for increased effectiveness in the tax system in Nigeria.
This is the first step in the taxation process. A tax statute must have a levying or charging clause on a taxable person. This is a provision in the statute that actually requires a person...
