Uzbekistan has made progress in fiscal reforms, but further steps are needed to improve economic stability and social equity. This study examines how successful fiscal models from Brazil, Indonesia, Vietnam, and Kazakhstan can be adapted to Uzbekistan’s economic and social landscape. The analysis highlights progressive taxation, targeted social assistance, and public investment as key factors in reducing poverty and ensuring sustainable development. Brazil’s high-tax, high-transfer model, Indonesia’s low-tax, targeted aid approach, Vietnam’s inclusive growth strategy, and Kazakhstan’s simplified taxation with broad social coverage provide valuable insights.
