Corporations basically don't pay taxes, even if they look like they are.
The CBO produced a report "THE INCIDENCE OF THE CORPORATE INCOME TAX" in which it states "A corporation may write its check to the Internal Revenue Service for payment of the corporate income tax, but that money must come from somewhere: from reduced returns to investors in the company, lower wages to its workers, or higher prices that consumers pay for the products the company produces."
And it goes on to say
"Although economists are far from a consensus about exactly who bears how much of the burden of the corporate income tax, the existing studies highlight the significant types of economic mechanisms as well as the empirical estimates necessary for further quantifying the burdens. CBO's review of the studies yields the following conclusions:
o The short-term burden of the corporate tax probably falls on stockholders or investors in general, but may fall on some more than on others, because not all investments are taxed at the same rate.
o The long-term burden of corporate or dividend taxation is unlikely to rest fully on corporate equity, because it will remain there only if marginal investment is not affected by those taxes. Most economists believe that the corporate tax system has some effect on investment decisions.
o Most evidence from closed-economy, general-equilibrium models suggests that given reasonable parameters, the long-term incidence of the corporate tax falls on capital in general.
o In the context of international capital mobility, the burden of the corporate tax may be shifted onto immobile factors (such as labor or land), but only to the degree that the capital and outputs of different countries can be substituted.
o In the very long term, the burden is likely to be shifted in part to labor, if the corporate tax dampens capital accumulation.
