OECD Forum on Tax and Crime

The OECD Forum on Tax and Crime is the premier global event on combatting tax crimes and other financial crimes. Held every 2-3 years, the Forum brings together senior policy makers and leading financial crime experts from tax and customs administrations, anti-corruption and anti-money laundering authorities, police, public prosecutors, financial intelligence authorities, development agencies, and international organisations, all of whom share responsibility for combating financial crime in all of its forms. Through a series of interactive plenary sessions and smaller, practical sessions, the Forum provides the ideal platform for law enforcement authorities to discuss the strategic, organisational, and operational aspects of tackling serious financial crime at both the national and international level.
