It provides internationally comparative data on global trends in tax administrations across 58 advanced and emerging economies. The report is intended to inform and inspire tax administrations as they consider their future operations, as well as to provide information on global tax administration trends and performance for stakeholders and policy makers. The report is structured around nine chapters that examine the performance of tax administration systems, using an extensive data set and a variety of examples to highlight recent innovations and successful practices.
