This chart shows how tax revenue from individual income taxes and corporate income taxes has changed over time. In fiscal year 2016, President Obama projects that individual income taxes will account for 46.7 percent of total tax revenue, while corporations will contribute 13.4 percent. The remaining 40 percent of federal revenue will come primarily from payroll taxes from Social Security and Medicare, as well as other sources such as customs and excise taxes.
