Wall Street journal op-ed, Time to Junk the Corporate Tax, by Michael J. Boskin (Stanford University, Hoover Institution):

Nobel Laureate Robert Lucas says reform would deliver great benefits at little cost, making it "the largest genuinely true free lunch I have seen.'

President Obama has put tax reform on the agenda, but surprisingly little attention is being paid to fixing the most growth-inhibiting, anticompetitive tax of all: the corporate income tax. Reducing or eliminating the corporate tax would curtail numerous wasteful tax distortions, boost growth in both the short and long run, increase America's global competitiveness, and raise future wages.

The U.S. has the second-highest corporate income tax rate of any advanced economy (39% including state taxes, 50% higher than the OECD average). Many major competitors, Germany and Canada among them, have reduced their corporate tax rate, rendering American companies less competitive globally.

Of course, various credits and deductions—such as for depreciation and interest—reduce the effective corporate tax rate. But netting everything, our corporate tax severely retards and misaligns investment, problems that will only get worse as more and more capital becomes internationally mobile. Corporate income is taxed a second time at the personal level as dividends or those capital gains attributable to reinvestment of the retained earnings of the corporation. Between the new taxes in the health reform law and the expiration of the Bush tax cuts, these rates are soon set to explode. …

Reducing or eliminating the negative effects of the corporate tax on investment would increase real GDP and future wages significantly. Junking both the corporate and personal income taxes and replacing them with a broad revenue-neutral consumption tax would produce even larger gains. Nobel Laureate Robert Lucas concluded that implementing such reforms would deliver great benefits at little cost, making it "the largest genuinely true free lunch I have seen."

Reducing taxes on new investment could help strengthen what is a historically slow recovery from such a deep recession. It would also strengthen the economy long-term. American workers would benefit from more jobs in the short run and higher wages in the long run.
