We synthesize the findings from several recent papers on South Africa's very high income inequality. These papers use new datasets—including income tax data—and new empirical methods to investigate the drivers of household income and individual earnings inequality in South Africa. Increased...

In this paper we explore options for augmenting South Africa's personal income tax revenue using two microsimulation models: PITMOD simulates the personal income tax system and is underpinned by a dataset comprising a full extract of anonymized individual-level administrative tax data; and SAMOD...

Rising levels of income inequality and tight government budgets have spurred discussions in many developing nations about how to appropriately tax high-income earners. In this paper, we study taxpayer responses to an increase in the top marginal tax rate in South Africa, drawing on exceptionally...
