The owner of a Charlotte-area scrap metal business pled guilty to tax evasion, according to the U.S. attorney for the Western District of North Carolina.

Tony Marks, 47, of Matthews, North Carolina, admitted to concealing personal earnings from the Internal Revenue Service.

Since 2011, Marks was self-employed as a scrap metal broker. According to the filed documents and Tuesday’s plea hearing, Marks concealed approximately $313,372 in earnings between 2011 and 2014.

According to the court records, Marks deposited checks and cash receipts from his business and its customers into multiple personal bank accounts.

Between 2011 and 2014, Marks earned additional personal income that he failed to report on his U.S. Individual Income Tax Return Form 1040 filed with the IRS. As a result of the unreported information, Marks had additional tax due.

One count of tax evasion carries a maximum penalty of five years in prison and a $250,000 fine.

Marks was released on bond following the hearing.
