While  money laundering is basically the process of taking dirty money and making it  clean, terrorist financing can be considered the opposite.  It’s the  process of taking mainly clean money and dirtying it by directing it to finance  or support terrorism or terrorist activity.   The money for terrorist financing, as in money laundering, can also come  from illicit sources.  The common factor  is that they both try to disguise the money.   Money laundering disguises it at the front end, where it originates,  while terrorist financing disguises it at the back end, at its destination. According  to the FATF, the term terrorist  financing includes the financing of terrorist acts, and of terrorists and terrorist  organisations.  Personal or business  donations are misdirected by account holders to their criminal colleagues in  what appear to be legitimate activities, such as charities or other institutions,  which conceal their funding of terrorism.
  Businesses and institutions are  also required by law to report to the BVI FIA any type of activity or  transaction that arouses suspicion of terrorist financing.
