The International Survey on Revenue Administration (ISORA) collects data on tax administration from administrations around the world using questions and definitions agreed by five international organizations: the International Monetary Fund (IMF), the Asian Development Bank (ADB), the Inter-American Center of Tax Administration (CIAT), the Intra-European Organization of Tax Administrations (IOTA), and the Organization for Economic Co-operation and Development (OECD).
ISORA 2023 is a more comprehensive survey than the surveys run over the past four years, covering more aspects of tax administrations' institutional arrangements and practices in areas such as compliance risk management and taxpayer services.
The workshop targets tax administrations' teams responsible for completing ISORA and seeks to:
- improve understanding of the survey and survey questions;
- provide practical information on how ISORA data can be accessed and used by administrations.
The workshop format includes presentations by IMF experts, hands-on working sessions, and peer-to-peer learning.

Prepare participants to complete ISORA 2023, leading to an improvement in ISORA 2023 data quality.
