The corporate income tax is the most poorly understood of all the major methods by which the U.S. government collects money. Most economists concluded long ago that it is among the least efficient and least defensible taxes. Although they have trouble agreeing on—much less measuring with any precision—who actually bears the burden of the corporate income tax, economists agree that it causes significant distortions in economic behavior. The tax is popular with the person in the street, who believes, incorrectly, that it is paid by corporations. Owners and managers of corporations often assume, just as incorrectly, that the tax is simply passed along to consumers.
