From the Financial Task Force blog:

"A new GFI report due out later this week, The Implied Tax Revenue Loss of Trade Mispricing, finds that developing countries are losing as much as $100 billion a year to just one form of tax evasion: trade mispricing.

'Furthermore, the report’s $100 billion figure is likely understated, as it only reflects tax revenue lost through trade mispricing occurring through re-invoicing. The report also only measures tax revenue lost on illicit money coming out of developing countries, it does not take into account money that is being held abroad.'"

Something to watch for. More details on magnitudes and measurements here.

Hat tip to TJN.

But now I know where the OECD is coming from on this issue.
