Tax Administration 2019: Comparative Information on OECD and other Advanced and Emerging Economies published by OECD (2019).
Together the 58 tax administrations participating in the eighth edition of the OECD’s Tax Administration Series (TAS 2019) collect net revenues of EUR 11.4 trillion (2017). They are large and complex organisations employing around 1.6 million staff. They deal with the tax affairs of around 810 million personal income tax and corporate taxpayers who contact tax administration in excess of 500 million times via telephone, in-person, e-mail or paper and generate more than 1.6 billion online contacts. And the tax administrations do this on a combined operating budget amounting to around EUR 71 billion, equivalent to less than 1% of total revenues collected.
