Tax incentives can have both positive and negative impacts on an economy. Among the positive benefits, if implemented and designed properly, tax incentives can attract investment to a country. Other benefits of tax incentives include increased employment, higher number of capital transfers, research and technology development, and also improvement to less developed areas. Though it is difficult to estimate the effects of tax incentives, they can, if done properly, raise the overall economic welfare through increasing economic growth and government tax revenue (after the expiration of the tax holiday/incentive period). However, tax incentive can cause negative effects on a government's financial condition, among other negative effects, if they are not properly designed and implemented.
