Is it true that progressive taxation reduces income inequality?
Partly. Several sources indicate progressive or tax-and-transfer systems reduce income inequality relative to pretax income, including a US Census analysis and a life-cycle model, though these are country-specific or model-based. Other sources report limited redistributive effects or inefficiency of progressive income taxation in particular regions, so the evidence covers the claim only in part and points both ways.
