Tax competition, a form of regulatory competition, exists when governments are encouraged to lower fiscal burdens to either encourage the inflow of productive resources or discourage the exodus of those resources. Often, this means a governmental strategy of attracting foreign direct investment, foreign indirect investment (financial investment), and high value human resources by minimizing the overall taxation level and/or special tax preferences, creating a comparative advantage.
Some observers suggest that tax competition is generally a central part of a government policy for improving the lot of labour by creating well-paid jobs (often in countries or regions with very limited job prospects). Others suggest that it is beneficial mainly for investors, as workers could have been better paid (both through lower taxation on them, and through higher redistribution of wealth) if it was not for tax competition lowering effective tax rates on corporations.
Some economists argue that tax competition is beneficial in raising total tax intake due to low corporate tax rates stimulating economic growth.  Others argue that tax competition is generally harmful because it distorts investment decisions and thus reduces the efficiency of capital allocation, redistributes the national burden of taxation away from capital and onto less mobile factors such as labour, and undermines democracy by forcing governments into modifying tax systems in ways that voters do not want. It also tends to increase complexity in national and international tax systems, as governments constantly modify tax systems to take account of the ‘competitive’ tax environment.
