Earlier this month, the Joint Chiefs of Global Tax Enforcement
(J5), hosted The Challenge, an event bringing together
investigators, cryptocurrency experts and data scientists, in order
to find the world's most egregious tax offenders. It was the
second time the event was held, and this year's focus was on
cryptocurrency-facilitated crime. The J5 was established in
mid-2018 by tax enforcement leaders from Australia, Canada, the
Netherlands, the United Kingdom and the United States, to combat
cross-border money-laundering, tax crime and cybercrime. After the
recent event, the criminal division of the U.S. Internal Revenue
Service (IRS) reportedly stated that it identified
"dozens" of potential cryptocurrency tax evaders.
