Corporate income taxes are levied by the U.S. federal government and by states on business profits. Understandably, companies try to use everything in the tax code to lower the cost of taxes paid by reducing taxable income.

Three Ways Corporations Avoid Paying Taxes

The U.S. tax rate is around 40 percent. That includes:

  • Federal tax rate of 35 percent for the highest income brackets.
  • State and local tax rates ranging from 0 percent to 12 percent. It averages out to 7.5 percent.
  • Companies deduct state and local tax expenses. That averages out to around 40 percent. 

But corporations don't actually pay that rate. The effective corporate tax rate is around 15 percent.  As of June 2014, the Treasury Department had collected $303 billion in the previous 12 months. That's just 15 percent of U.S. corporate profits of $2 trillion.

That's about half the effective rate the government received in June 2007, just before the recession hit. Corporate taxes yielded their pre-recession peak of about $383 billion at that time. The government is receiving a lower share of companies' profitability. Corporate profits exceeded their pre-recession peak two years ago.

How do corporations avoid paying taxes? First, many companies, especially banks, are still writing off losses they incurred during the financial crisis.

Second, almost half of all corporations are . They pay no corporate taxes.

That's because they pass corporate income, losses, deductions, and credits through to their shareholders. The shareholders are then taxed on these profits or losses at their income tax rates. 

A third reason is that companies are back into those local markets. They might prefer to bring the cash home, but are deliberately avoiding U.S. taxes.

It's actually cheaper for them to borrow at current low interest rates in the United States than to bring earnings home. As a result, corporations are debt-heavy in the United States, and cash-rich in overseas operations. 

In fact, corporations have become so that it's become a competitive advantage. They can make more money in U.S. markets than foreign competitors because of their knowledge of the tax code and how to get around it. That's one reason you may never see a tax overhaul. Corporations that are successful in the current tax environment don't want to see the rules, which they've mastered, change. 

History of Corporate Taxes

Before the 1894 Revenue Act, taxes were levied on the individual owners of businesses, but not on the corporations themselves. Although the Act was ruled constitutional, it was replaced by a Tax Act in 1909, the first year that corporate taxes were levied.

The maximum tax rates below are the rates paid on the highest income levels. Please note that the definition of income changes frequently, so keep that in mind when comparing rates. 

Until 1936, all companies paid the same rate, regardless of income.
