Corporations like to complain that their federal income tax rates are too high. But lost amid the clamor to cut taxes for corporations is the fact that U.S. corporations are paying a far lower share of our nation’s total tax revenues. In fact, many of the nation’s largest companies are paying little or no federal taxes at all.
The top federal income tax rate for corporations, as for some individuals, is 35 percent. But while the top income tax rate is the same for individuals and corporations, corporations have been paying a lower share of our nation’s total taxes. Overall, the nation’s federal revenue from corporate income tax receipts, as a percentage of the nation’s gross national product, dropped dramatically to one-sixth of that in the 1950s.
As the corporate share of our nation’s federal tax revenue has fallen, individual Americans have paid a relatively higher percentage of federal tax revenue. Corporate taxes fell from 26.4 percent of total tax revenue in 1950 to just 7.4 percent of total tax revenue in 2010. During this same period, personal income, Social Security and Medicare taxes increased from 51.4 percent to 83.8 percent of total tax revenue.
Thanks to numerous tax breaks and loopholes, corporations rarely pay the full corporate income tax rates. A 2011 report by Citizens for Tax Justice and the Institute on Taxation and Economic Policy found that 78 of 280 of the nation’s largest and most profitable companies paid no federal income taxes in at least one of three years. Overall, the study found that the Fortune 500 companies included in the survey paid 18.5 percent in taxes, or about half the corporate income tax rate of 35 percent.
Perhaps even more startling, many of the largest companies are now paying less tax than before the Wall Street financial crisis and economic recession, even though their profits have recovered. Cash tax payments by non-financial companies in the S&P 500 index fell 13.2 percent to $222 billion in 2010 from 2007, according to Bloomberg data, while net income rose 12.5 percent to $612 billion.
How do they do it? One tax avoidance strategy that many companies use to enrich their top executives is to pay hefty amounts of stock options. The tax code allows companies to deduct the appreciated value of stock options when their executives exercise them, instead of the lower value of the stock options at the time they were granted.
For years, Sen. Carl Levin (D-Mich.) has been pushing for legislation that would limit the tax deductions companies could claim on stock options. The bipartisan Joint Committee on Taxation has estimated that if the Levin bill were enacted it would add $25 billion in revenue to the federal government over the next decade. 
Another corporate tax avoidance strategy is to move overseas to an offshore tax haven like Bermuda. By reincorporating offshore, companies avoid paying federal income taxes on profits earned outside the United States. This strategy of registering in an offshore tax haven is particularly attractive for hedge funds. Hedge Fund Research estimates that of the $1.86 trillion invested in hedge funds, $1.25 trillion is kept offshore.
