It is a known fact that taxation is one of the major sources of government funds. There are various forms of levies in Nigerian tax system, among these is Company Income Tax. The present study focuses on the significance of Company Income Tax on Nigerian economy and its effects on Nigerian companies, a case study of Union Bank Plc, Illorin. Company Income Tax is a levy, which is imposed on Nigerian companies and its objectives is to examine the way company income tax is being administered as well as other related taxes, it also contain formulated hypothesis. A sample size of the top management staff within the Accounting Department was used. Out of the 40 workers, a sample size of 30 respondent were drawn. The data obtained were represented in a tabular form and the use of chi-square statistical table was used in testing the hypothesis which helps to determine the premises of accepting or rejecting the hypothesis. From the research, it was discovered that company income tax has adverse effect in various form on Nigerian companies. Since research is an on going process, no study could be exhaustive.

The numerousity of government wants at the expense of its limited resource make it imperative to source for funds through other means. One of the forms through which government source for funds to meet its obligation is taxation. The versatility of taxation cannot be overemphasized. This is true because it does not only serve as one of the major sources of government revenue through which public interests are satisfied but also it is one of the major fiscal policy measure being used in stabilizing the economy. For instance, it can be used to curtail the velocity of money when inflation arises. Taxation also serves as an effective way of redistributing income among citizens of a nation. In fact, taxation plays a crucial role in promoting economic activity and growth. through taxation, government ensures that resources are channelled towards Important projects in the society (Emeni, 2000). It is necessary to mention that during the pre-colonial period, taxation functioned more or less on an ethnic basis. The Nigerian tax system took after the British tax system both in administration and governing enactments. It is therefore not surprising that income tax as we know it today was first introduced into Nigerian by the British through Lord Lugard in 1904 in the North (Abdul Razaq, 1993).  The Nigerian tax system has about ninety various forms of levies which it imposes on the citizens and companies. These taxes fall under two basic categories, which are direct and indirect taxes. Direct taxes are those taxes that are levied on incomes/profits of individuals, partnership and companies. These levies have direct incidence and Impact on tax payer. Examples of direct taxes include personal income tax, company income tax, which this research work is focused upon, capital gain tax, petroleum profit tax and capital transfer tax which had been abolished in Nigerian with effect from 1st January 1996 (Abdul Razaq, 1993 and Osita, 1999). These taxes are governed by Decrees, Acts, and Case Laws, which constitute the statute is force today, personal income tax, company income tax, capital gain tax and petroleum profit are governed by Income Tax Management Act 1961, Company Income Act 1979, Capital Gain Tax Act 1967 and Petroleum Profit Tax 1959 respectively. Company income tax is governed by Company Income Tax Act of 1979. This Act consolidated the Company Income Tax Act 1961 and other amending legislations. This is true because existing Laws and Acts are only amended since no new ones have been enacted. Part 1, Section 1 of the Company Income Tax Act 1979 provides that “administration of company income tax is to be by a Board of which the official name shall be the Federal Board of Inland Revenue”. Thus, Federal Board of Inland Revenue is responsible for the administration of company income tax which governs company income tax. The other category of taxes which is indirect taxes are those taxes levied on the manufacturers, wholesalers and importers of goods and services in which effects are shifted wholly or partly to the final consumers of such goods and services. Example includes custom duty, Import duty and Value Added Tax (VAT). Having taken interest in the happenings in recent time on Nigerian tax system and current economy trend in the country, this research work is focused on the significance of company income tax on Nigerian economy and its effects on Nigerian companies.


Despite the significance of taxation, it is clearly noticed that it has various impact which include; Company income tax is imposed on taxable profit of the company, which reduce the investment capacities of the company. The company income tax has some adverse effects on the performance and financial position of the companies. According to Abdul Razaq (1998), the tax system makes it more expensive for a company to maintain its net flow of dividend to its shareholders. Withholding tax, which is a tax deductible from source, on the sum of all form of contract and services of the companies, has the capacity of tying down the capacity of companies. Also education tax makes the companies to pay excess taxes, which result in reduction of their profits. The retained earnings of companies are adversely affected.


It is not an understatement that income tax has adverse effects on Nigerian companies, despite all its benefits on the Nigerian economy. In the light of the above, this study extensively explains the company income tax by;  examining the way it (company income tax) is being administered as well as other related taxes.  analyzing various ways through which Nigerian companies are affected by the imposition of company income tax. providing useful suggestions and recommendations to the foregoing.
