Inequality

South Africa has one of the most progressive income-tax systems in the world. Income tax significantly reduces market-income inequality by flattening the incomes of the rich and providing financing for instruments of social protection, such as the social grants system and free basic services. Personal Income Tax is the government’s largest tax instrument and has increased as a share of tax revenue over the past decade. However, it has become less progressive over time, when measured as a share of income despite rate increases. While the amount of income tax has increased, market incomes, particularly of the top decile, have grown at a greater rate.
