Three Sources of Government Funding:
Fees (User Charges): Payments from individuals for specific services.
Taxes: Compulsory financial charges imposed by the government.
Borrowing: Government debt instruments to fund activities.
Tax Base:
The value of goods, services, wealth, or income subject to taxation.
Tax Rate:
The percentage of the tax base that must be paid to the government.
Marginal Tax Rate:
Formula: ( \frac{\Delta \text{taxes due}}{\Delta \text{taxable income}} )
Tax Bracket:
A specific interval of income that applies to a unique marginal tax rate.
Average Tax Rate:
Total tax payment divided by total income.
Proportional Taxation:
Tax bill comprises the same percentage regardless of income level.
Example Calculation:
Income of $10,000 at 20% = $2,000;
Income of $100,000 at 20% = $20,000.
Progressive Taxation:
Higher incomes incur a higher percentage of tax on additional income.
Example:
Income from $0–$10,000 taxed at 5%,
$10,001–$20,000 at 10%, up to $20,001–$30,000 taxed at 30%.
Regressive Taxation:
Tax burden decreases as income increases, leading to a lower effective tax rate at higher incomes.
Example:
Income of $50,000 at 10% = $5,000;
Income of $100,000 at 5% = $5,000.
