Missing trader fraud: Missing trader fraud (also called missing trader intra-community, MTIC, or carousel fraud) is the theft of Value Added Tax (VAT) from a government by organised crime gangs who exploit the way VAT is treated within multi-jurisdictional trading where the movement of goods between jurisdictions is VAT-free.  This allows the fraudster (person who commits fraud) to charge VAT on the sale of goods, and then instead of paying this over to the government's collection authority, to simply abscond, taking the VAT with him.  The term "missing trader" refers to the fact that the trader goes missing with the VAT.  "Carousel" refers to a more complex type of fraud in which VAT and goods are passed around between companies and jurisdictions, similar to how a carousel goes round and round.
