What is the average effective federal corporate income tax rate in the United States?
In 2013 (latest IRS data), the average effective federal corporate income tax rate was 23%. The difference between this figure and the 35% corporate marginal tax rate is the result of tax preferences. Tax preferences give certain corporations special tax breaks that lower their effective tax rates. Out of 20 major industries in 2013, the average effective corporate income tax rate ranged from as low as 17% for accommodation and food services to as high as 33% for healthcare and social assistance. Owners of corporations also pay taxes on their profits through taxes on capital gains and dividends.
