The nature of international tax means that national revenue agencies and policy makers speak to each other all the time. Groups such as Jitsic (the joint international tax shelter information centre), which brings together the US, the UK, Canada and Australia in an effort against unlawful tax avoidance and the Leeds Castle group of national tax authorities, which as well as the four previously mentioned, includes China, France, Germany, India, Japan and South Korea, discuss best practices in matters such as compliance and administration. National tax authorities also take part in the work of multinational organizations such as the UN, the EU and the OECD.
