IMF DATA

The International Survey on Revenue Administration (ISORA) is the product of a collaboration between the Asian Development Bank (ADB), the Inter-American Center of Tax Administrations (CIAT), the Fiscal Affairs Department (FAD) of the IMF,  the Intra-European Organisation of Tax Administrations (IOTA), and the Organisation for Economic Co-operation and Development (OECD). ISORA collects data on revenue collections, tax administration resources, tax administration operations, and other characteristics and practices of tax administrations. 
 
This ISORA portal provides information about the survey, the questionnaires and guides used to complete the survey, publications and presentations using ISORA data, and of course, ISORA data.
