Bow Wow needs to hire himself a new accountant -- because not only does he have a tax lien against him for unpaid taxes from 2006 ... but now it turns out he owes back taxes from 2008 and 2010 as well!
As TMZ first reported, a tax lien in Florida for the year 2006 put Bow Wow on the hook for $91,105.61. The lien has still not been paid off.
