The Brooklyn, N.Y., resident was among 44 people arrested in July in a two-track investigation into international money laundering and political corruption.
The 34-year-old worked as a real estate developer in New York and New Jersey.
Haber admitted helping government witness Solomon Dwek launder money used to bribe a Union City official in exchange for permits.
Haber is the fifth person to be sentenced in the overall case, but the first among the defendants accused of money laundering.
The sentenced was handed down Tuesday in Newark.
