Moneyweb in South Africa has reported that the South African Revenue Service, responsible for collecting tax in the country, uses Tax Justice Network information to help it in its work. Their spokesperson, Adrian Lackay is reported as saying:
Revenue is using TJN’s information to understand international tax trends, tax evasion and avoidance, and examine how money is hidden
We know they're not alone. And we're pleased to help.
Mind you, some funding would also be of benefit as well. We can't live on thin air.
