Drawing on our new companion paper, we first identify the tax base and discuss the design of potential tax schedules. Testing alternative tax schedules, we estimate how much additional revenue could be collected from a progressive tax on the top 1% richest South Africans. Our results show that under conservative assumptions, a wealth tax could raise between 70 and 160 billion Rands—1.5% to 3.5% of the South African GDP.We discuss in turn how sensitive our estimates are to assumptions on (1) mismeasurement of wealth and (2) tax avoidance and evasion, based on the most recent tax policy literature. We examine technical issues related to the enforcement of the tax, and how third-party reporting and pre-filled declarations could be used to optimize measurement of taxable wealth and minimize evasion and avoidance opportunities. Finally, we explain how this new tax could interact with other capital related taxes already in place in South Africa, and discuss the potential impact on growth.en©2021 Southern Centre for Inequality Studies (SCIS)Wealth InequalityWealth taxFiscal sustainabilityCOVID-19 crisisMismeasurement of wealthTax avoidance and evasionWorking Paper
