Review Questions

• How does the structure of the federal income tax system affect individuals with varying income levels?
  • The federal income tax system is designed to be progressive, meaning that as an individual's income increases, they move into higher tax brackets with higher rates. This structure helps ensure that those with greater financial resources contribute more in taxes than those with lower incomes. Consequently, individuals with varying income levels will see different effective tax rates based on their earnings, encouraging a more equitable distribution of the tax burden.
• What are the key differences between deductions and tax credits in relation to federal income tax calculations?
  • Deductions and tax credits both help reduce a taxpayer's overall liability but do so in different ways. Deductions reduce taxable income, which lowers the overall tax amount based on the applicable tax rate. In contrast, tax credits provide a dollar-for-dollar reduction of the actual taxes owed. This means that while deductions can lead to savings proportional to one's tax rate, credits offer a more direct and impactful way to decrease taxes payable.
• Evaluate how changes in federal income tax rates can impact economic behavior among individuals and businesses.
  • Changes in federal income tax rates can significantly influence economic behavior by affecting disposable income and investment decisions. Lowering rates may encourage individuals to spend more or invest in businesses due to increased after-tax earnings, which can stimulate economic growth. Conversely, raising rates might lead individuals and businesses to save more or reduce spending, potentially slowing economic activity. Thus, policymakers must consider these behavioral responses when proposing changes to the federal income tax system.
