  • Background to the Study

Social scientists maintain that there is a social contract between the people and the government whereby the former accept of forget some of their fundamental rights and also make certain contributions in return for the provision of common services by the latter. Alas (2003). These common services include the maintenance of internal and external security, provision of health and educational facilities, roads, electricity, communication network and so on. To enable the government carry out these welfare services or responsibilities. It is imperative that adequate finances be raise. One of the means through which such funds are raise by government is taxation, Ebiringa and Emeh (2012). Taxation can be defined as a system and procedure adopted by government to raise revenue. It is also the process of employing method of raising money for government by the imposition of taxes on goods and services. A substantial part of government revenue comes from tax. Olorunleka (1985), also define taxation as the process or machinery by which a community or group of people is made to contribute part of their income in some agreed quantum and method for the purpose of the administration and development of the society.

Ola (1999) defined tax as a compulsory financial contribution made to the government by individual and corporate bodies. It is a form of withdrawal made by government for a particular or some economic development purpose. Tax as a compulsory contribution from a person to government is to defray the expenses incurred by the common interest of all without reference to social benefit.

The essence of taxation is to generate income for the government, and the money realized from tax is used by the government to provide economic development and social benefit to the public such as education and wealth, redistribution of income, economic development, maintenance and construction of roads, provision of pipe borne water etc, and also to meet government demand and financial responsibility in Nigeria.

Income tax applies generally to the commodities consumed by the private sector (i.e, household, individuals and businesses) and their income. It is one of the fiscal tools government use in both developing and developed economies to achieve the goals of economic growth. The legal basis for personal income tax is found in the provision of the personal income tax decree (now Act) 104 of 1993 thereafter sub-sequence amendment Act has taken place till date. Every tax payer in Nigeria is liable to pay tax on the aggregate amount of his income whether derive from within or outside Nigeria, the salary, wages, fees, allowance and other gains of benefit given or granted to an employee are chargeable tax. In the view of Okafor (2012), Income tax is levied on income such as salaries, interest, dividends, commission, royalties and rent. Income tax yields very substantial revenue to government. Therefore, it has a bearing on the Gross Domestic Product (GDP) which is the standard indicator for measuring the economic wellbeing of a nation. But the feature of compulsory levy inherent in tax is usually under mined because people dislike the civic responsibility that the payment of tax connotes. In Nigeria, people especially the rich and the elites, deliberately dodge the civic responsibility and sometimes employ the service of tax specialists in order to pay less tax to government. There is also problem of falsification of ages and the number of children and dependents one’s has in order to reduce the amount of tax payable Ebiringa and Emeh (2012).

Ariwodola (2000) in its text introduced solution as regard strategies to be adopted by revenue authorities for expanding the income tax net to improve personal income tax collection drive covering the self-employed to increase revenue for the economic growth and development in Nigeria.

This situation is becoming even more compounded by the obvious dividing feature of our oil economy. Inspite of the broadness and the comprehensive nature of our tax system, tax avoidance and evasion are on the increase. The ugly development has placed most state government in a situation where they cannot cope with their civic responsibilities to their citizens, hence a compelling need to put an end to this unwhole some circumstance in Nigeria through proper problem identification. Due to lack of fund arising from low revenue receive from personal income tax. It has not contributed some basic amenities to the economic growth and development of Nigeria, Problem regarding poor method of collections of income tax which have reduce a part of revenue of income tax for economic growth and Citizen do not enjoy some basic amenities benefit because of not payment of income tax.
