Corporate taxes are inefficient, with much greater deadweight costs than most other taxes. The optimal corporate tax rate is zero. Bad policies are often good politics. Most voters are easily deluded into thinking that corporate taxes impose no cost on them. Cutting corporate tax and increasing personal taxes is a vote loser. Politicians around the world have cut corporate tax rates, not because they have decided to put the welfare of the population ahead of electoral self-interest, but due to tax competition. The electoral cost of the economic effects of increased capital flight would be greater than the electoral gains from holding up corporate tax rates. Politicians outside tax havens are reluctant corporate tax-cutters and, thus, reluctant participants in tax competition. Ending such competition would suit them better than winning it. Hence their crackdown on the tax havens that provide the competition.
