Explain the difference between a progressive tax and a regressive tax with Australian examples.

• A. A progressive tax takes a larger share from low-income earners.
• B. A regressive tax raises more from high-income earners.
• C. Progressive tax raises a higher percentage of income from higher earners (e.g., personal income tax).
• D. Both taxes have the same impact on income groups.

Answer: (C)

A progressive tax system increases the rate as income rises, so higher earners pay a larger share of their income in tax. In Australia, personal income tax is designed this way with rising marginal rates: the first portions of income are taxed at low or zero rates, then higher brackets apply (e.g., 19%, 32.5%, 37%, up to 45%), so someone with a higher income ends up paying a larger percentage of their income overall. The Medicare levy adds a small flat percentage, but the overall effect remains that the burden grows with income. This is different from a regressive tax, which would take a bigger share from lower-income earners. A common Australian example is the GST at 10% on many goods and services; because lower-income households spend a larger portion of their income on taxed goods, GST reduces a larger share of their income, making it regressive in impact.
