Background to the study.

Over the years, one of the main issues developing countries have faced is sustainable economic growth. To keep up with the tremendous demand for government need to raise revenue to carry out its duties. The single most important way government raise funds to finance its operations is through taxes (Osundina and Olanrewayu 2013: 76). Tax is a major player ofevery nation of the world and tax system put in place an opportunity for government to collect additional revenue needed in discharging it's obligations.

The economic effects of taxation include micro effects on the distribution of income and efficiency of resource use, as well as, macro effect on the level of capacity output, prices, employment, and growth. Hence, taxation tends to affect productivity and resources allocation in the economy.

It is important to note that asides the fact that taxation is an important source of generating revenue for the government, it is also an avenue for the redistribution of wealth and re-adjustment of the economy (Ojo 2008) cited in (Abata 2014: 110). The tax system is one of the most powerful levies available to any government to stimulate and guide its economic and social development (Abata 2014: 110). Furthermore, according to Roche (2015: 1), corporate taxation is of great concern in investors' decisions and hence wetin employment and economic growth.

Taxation has different impacts depending on the form it assumes. Corporate and Shareholder taxes reduce the capital funds available to make investments and build a general and more productive structure (Roche 2015:2).
