As Young Buck readies his lawsuit against 50 Cent and the rest of his former G-Unit crew, his former business manager has responded to allegations that his negligence led to Buck's recent financial troubles.

On August 3, the IRS raided Buck's house in Tennessee, claiming he owed close to $300,000 in back taxes. "This IRS situation came about because I trusted accountants, lawyers, and managers to handle my business for me while I focused on making music," Buck, born David Brown, said in a statement about the raid. "From now on, I am going to stay on top of my own business."

However, Buck's former CPA Bruce Seckendorf, whose past clients have also included 50, Eminem and Joss Stone, claims that he is in no way responsible for any wrongdoing.

"Clearly, I'm not worried about it," Seckendorf scoffed. "I don't think it has any merit. I know I did nothing wrong. I'm not going to talk specifically about how [Young Buck] spent his money, but I view my job as the gatekeeper. Money comes in [and] we pay bills. He made his own financial decisions."

Seckendorf went on to argue that he was working to keep the IRS "at bay" until Buck fired him, and if anyone is responsible for Buck's tax issues, it is the accountant who was hired to replace him.

"I totally knew what he owed the IRS and I was keeping them at bay," Seckendorf continued. " ... I sent an email saying David Brown owes this money to the IRS. You need to address immediately. ... I advised him how we need to attack this, setting up a payment plan, [etc, but] he let me go. The new guy's supposed to run with it. What takes place after March and when they raided his house, I can't comment on. But I can tell you, chances are, they ignored the IRS and that's what's gonna happen when you ignore the IRS and you owe them a lot of money."

Buck was forced to file for bankruptcy earlier this month, as a result of his financial woes.

His lawsuit against 50 Cent and G-Unit has yet to be filed.
