Corporations in the United States pay federal corporate income taxes levied at a 21 percent rate. Many states also levy taxes on corporate income. Forty-four states and D.C. have corporate income taxes on the books, with top rates ranging from North Carolina’s single rate of 2.5 percent to a top marginal rate of 11.5 percent in New Jersey. Fourteen states levy graduated corporate income tax rates, while the remaining 30 states levy a flat rate on corporate income.

In Nevada, Ohio, Texas, and Washington, corporations are subject to gross receipts taxes in lieu of corporate income taxes. Delaware and Oregon impose a tax on corporate income and a separate levy on gross receipts.

The state with the highest combined corporate income tax rate is New Jersey, with a combined rate of 30.1 percent. Corporations in Alaska, California, Illinois, Iowa, Maine, Minnesota, and Pennsylvania face combined corporate income tax rates at or above 28 percent. Six states—Ohio, Nevada, South Dakota, Texas, Washington, and Wyoming—face no state corporate income tax and only pay the federal tax rate of 21 percent.
