What type of taxation structure requires individuals with higher incomes to pay a larger percentage of their income in taxes?

Progressive taxation is designed so that individuals with higher incomes pay a larger percentage of their income in taxes compared to those with lower incomes. This system aims to reduce income inequality and ensure that tax burdens are distributed more fairly based on individuals' ability to pay.

As income increases, the tax rate also increases, which means that wealthier individuals contribute a greater share of their income to public revenues. This structure is often justified on the grounds that those who have more resources can afford to contribute more to fund government services and programs, benefiting society as a whole.

In contrast, other taxation structures do not operate on this principle. Regressive taxation imposes a higher relative burden on lower-income individuals, flat taxation applies a single tax rate regardless of income level, and fixed taxation involves set amounts payable that do not vary with income, which can disproportionately affect those with lower earnings.
