The Internal Revenue Service has filed a tax lien for nearly $185,000 against Marvin Gaye III, the adopted son of the famed Motown singer.

The agency filed the lien against Gaye on November 4, according to the Detroit News. His business manager, however, said that he has been working out his tax debts with the IRS and that a settlement was near.

Gaye, whose father was shot and killed by his grandfather in 1984, has been actively engaged in defending his father’s copyrights and has sued radio stations and restaurants for infringement. Gaye was also sued in 2007 by the son of the late singer Lou Rawls, Lou Rawls Jr., who claimed he was attacked by four large dogs that bit and clawed him during a visit to Gaye’s home.
