OECD’s annual statistical publication that presents a unique set of detailed and internationally comparable tax revenue data in a common format for all OECD countries from 1965 onwards.  It also provides a conceptual framework defining which government receipts should be regarded as taxes and classifies different types of taxes.  Comparable tables show revenue data by type of tax in US dollars, as a percentage of GDP, and, for the different types of taxes, as a share of total taxation.  Detailed country tables show information in national currency values.
