A money-laundering convict from Miami has been charged for filing false claims with the IRS and obstructing the agency's law for seeking $15 trillion in tax refunds.

Marlon T. Moore, 38, filed three separate income tax returns seeking tax refunds of $5.95 trillion, $2.97 trillion and $6 trillion after his release from a prison in Florida in 2007. He used fraudulent documents as basis for the claims.

The U.S. Attorney's office in Miami, however, said Moore knows the government doesn't owe him the said amount.

If convicted of the charges, Moore faces five-year sentences for each false claims and a three-year sentence for obstructing IRS laws.
