THE PROBLEM WITH THE CORPORATE TAX
June 3, 2008
Sen. John McCain (R-Ariz.) wisely proposed reducing the corporate tax rate from 35 percent to 25 percent. High corporate tax rates lead to low returns on capital, lower wages, or higher prices -- or all three, says , says N. Gregory Mankiw, a professor of economics at Harvard University.
- In a 2006 study, the economist William C. Randolph of the Congressional Budget Office (CBO) concluded that domestic labor bears slightly more than 70 percent of the burden from the tax.
- A recent Oxford University study examined data on more than 50,000 companies in nine European countries and concluded that a substantial part of the corporation income tax is passed on to the labor form in the form of lower wages; in the long-run, a $1 increase in the tax bill tends to reduce real wages at the median by 92 cents.
- A CBO report in 2005 concluded that the distortions that the corporate income tax induces are large compared with the revenues that the tax generates.
In 2007, corporate taxes brought in $370 billion, representing 14 percent of federal revenue. Cutting the tax rate to 25 percent would cost the Treasury about $100 billion a year. A decrease in the corporate tax would lead to increased economic growth, which tends to raise tax revenue from all other tax sources, says Mankiw:
- To the extent that shareholders would benefit, they would pay higher taxes on dividends, capital gains and withdrawals from their retirement accounts.
- To the extent that workers would benefit, they would pay higher payroll and income taxes.
A recent study by the American Enterprise Institute examined data from countries in the Organization for Economic Cooperation and Development and found that these effects are strong enough to make a corporate rate cut self-financing.
