Understanding Tax Codes

Features of Tax Codes

  • Purpose of Taxes

    • Raising Revenues:

      • Funds government programs not provided by markets, such as:

        • Defense: National security and protection

        • Education: Public education systems

    • Transfer Payments:

      • Redistributes income to help those in need.

      • Major focus on the elderly, primarily through:

        • Social Security

        • Medicare

      • Other low income support programs included.

    • Financing Government Operations:

      • Covers salaries and costs of running government.

    • Correcting Market Failures:

      • Addresses issues where markets fail to provide optimal goods/services.

Types of Taxes Levied by Federal Government

  • Individual Income Taxes:

    • Filed annually, typically complicated.

  • Payroll Taxes:

    • Directly deducted from paychecks to fund transfer programs.

  • Corporate Income Taxes:

    • Tax on corporate profits.

    • Concept of economic incidence is key:

      • Taxes ultimately affect people: shareholders, workers, and consumers.

      • Tax burden can come from lower profits, lower wages, or higher prices.

State and Local Government Taxes

  • State Taxes:

    • Mix of income taxes and sales taxes.

  • Local Taxes:

    • Often rely on property taxes based on land and building values.

Tax Terminology

  • Average Tax Rate:

    • Total taxes paid divided by total income

    • Formula: Average Tax Rate = Total Taxes Paid / Income

  • Marginal Tax Rate:

    • Tax paid on each additional dollar earned

    • Reflects change in tax liability with a change in income.

Tax Code Example

  • Progressive Tax System:

    • Initial income ($0 - $50,000): Tax rate = 0%

    • Income above $50,000: Tax rate = 50%

  • Understanding the Example:

    • Income of $40,000:

      • Tax: $0, Average tax rate: 0%, Marginal tax rate: 0%.

    • Income of $50,000:

      • Tax: $0, Average tax rate: Still 0%; marginal changes to 50%.

    • Income of $100,000:

      • Tax on first $50,000: $0; next $50,000 (at 50%): $25,000 total.

      • Average tax rate = 25% (i.e., $25,000 / $100,000).

Decision-making Affect of Tax Rates

  • Tracy’s Job Scenario:

    • Work Value: $20/hour (job's wage).

    • Opportunity Cost: $12/hour worth of leisure.

    • Calculation when earning above $50,000:

      • $100 job pays $50 after 50% taxes → less than leisure value.

      • Tracy won’t take the job (decision driven by marginal rate, not average).

Tax System Types

  • Progressive Tax Code:

    • Higher income leads to higher average tax rates.

  • Proportional Tax Code:

    • Consistent average rates regardless of income.

  • Regressive Tax Code:

    • Higher income leads to lower average tax rates.

Conclusion

  • Understanding Taxation's Role:

    • U.S. has an extremely progressive tax system compared to other countries.
