Dame Dash has filed a $3.5 million lawsuit against his accountant Barry Klarberg, accusing him of bungling years’ worth of tax returns.

Klarberg – whose celebrity clients also include singer Justin Timberlake and Rangers great Mark Messier – allegedly botched Dash’s New York and New Jersey income tax returns for 2000, 2001 and 2002.

Other alleged offenses by Klarberg include miscalculating how much Dash owed in 2005 and not telling him how much he made from the sale of one of his companies. In recent years, Dash has pawned off his Roc-A-Fella Records label and Rocawear clothing line. Klarberg, who wrote “Winning Tax Strategies and Planning for Athletes and Entertainers,” is a financial adviser to more than 600 jocks, actors and wealthy families.

“It is possible for some entertainers and athletes to be living high on the hog one day and down with the hogs the next,” Klarberg once said.
