About
The J5 was formed in response to the OECD’s call to action for countries to do more to tackle the enablers of tax crime. The J5 works collaboratively with the OECD and other countries and organizations where appropriate.
The Joint Chiefs of Global Tax Enforcement (known as the J5) are committed to combatting transnational tax crime through increased enforcement collaboration. We will work together to gather information, share intelligence, conduct operations and build the capacity of tax crime enforcement officials.
The J5 is comprised of Australian Taxation Office (ATO), the Canada Revenue Agency (CRA), the Fiscale Inlichtingen- en Opsporingsdienst (FIOD), HM Revenue & Customs (HMRC), and Internal Revenue Service Criminal Investigation (IRS-CI).
We are convinced that offshore structures and financial instruments, where used to commit tax crime and money laundering, are detrimental to the economic, fiscal, and social interests of our countries. We will work together to investigate those who enable transnational tax crime and money laundering and those who benefit from it. We will also collaborate internationally to reduce the growing threat to tax administrations posed by cryptocurrencies and cybercrime and to make the most of data and technology.
