Officials in Israel believe Bar Refaeli tried to hide more than $6 MILLION from tax authorities ... and now she's been informed prosecutors will hit her with tax evasion and money laundering charges.
Refaeli has been under investigation for years -- authorities believe she tried to get out of paying taxes in Israel by claiming her primary residence was in the U.S. ... and telling U.S. authorities she lived in Israel.
Authorities claim the supermodel was shady with tax officials from 2006 to 2012 -- part of that time was when she was dating Leonardo DiCaprio.
