The federal government relies on several key sources of revenue to fund its operations, with the bulk of the revenue coming from the types of taxes previously discussed. To elucidate, the three primary sources that make up approximately 92.3 percent of federal tax revenues include:
- Individual Income Taxes: The largest source of federal revenue, this is the tax levied on the income of individuals. It operates on a graduated scale with rates increasing as income increases.
- Corporate Income Taxes: Although a smaller percentage compared to individual income taxes, corporate taxes are a significant federal revenue stream. It includes taxes on domestic and foreign earnings of corporations operating in the US.
- Social Insurance (Payroll) Taxes: These taxes are the second-largest source of federal revenue. They are earmarked for specific programs such as Social Security and Medicare, and both employers and employees are mandated to contribute.
Understanding the magnitude and breakdown of these sources helps provide insight into how the government plans its spending and where taxpayer money is allocated.
