The eighth edition of the OECD's Tax Administration Series, this report provides internationally comparative data on aspects of tax systems and their administration in 58 advanced and emerging economies. The publication presents the results of the 2018 International Survey on Revenue Administration (ISORA), a multi-organisation international survey to collect national-level information and data on tax administration governed by four partner organisations: CIAT, the IMF, IOTA and the OECD. For the 2018 survey round, the Asian Development Bank (ADB) agreed to participate along with the four partner organisations.

In a global economy where multinational enterprises (MNEs) play a prominent role, governments need to ensure that the taxable profits of MNEs are not artificially shifted out of their jurisdiction and that the tax base reported by MNEs in their country reflects the economic activity undertaken therein. For taxpayers, it is essential to limit the risks of economic double taxation.
