Why surtaxes are foolish
A surtax to pay for healthcare? Not good. Former Bush White House economist Alan Viard explains:
First, it would significantly increase marginal tax rates for the affected households, giving them greater incentives to reduce their taxable income through various avoidance strategies. Even with moderate responsiveness to incentives, the revenue generated by the surtax would be significantly smaller than the burden that it would impose on affected taxpayers.
Second, the surtax would significantly increase the marginal tax rate on saving and investment by the affected households, whether done through corporate or noncorporate firms. The impact would be magnified because these households, despite their small numbers, account for a large portion of national saving. The resulting drag on capital accumulation would lower real wages for workers throughout the economy.
Third, the proposed surtax reflects an unsustainable approach to tax and fiscal policy. As commentators across the political spectrum have recognized, the existing fiscal imbalance cannot be addressed without imposing sacrifices on a broad segment of the population. Any new spending programs, such as those in H.R. 3962, will impose additional burdens. By linking these programs to a tax imposed on only 0.3 percent of the population, the bill obscures that fiscal reality. If the programs in H.R. 3962 are worthwhile, they are worth paying for in an open and broad-based manner.
