Thunder forward Kevin Durant is suing his former accountant over what the star NBA star says are mistakes in his taxes.

Attorneys for Durant say in the federal lawsuit filed last month that California-based accountant Joel Lynn Elliott deducted some personal expenses as business expenses on Durant's tax returns without proper documentation. The expenses include personal travel and a personal chef.

The lawsuit says Elliott prepared Durant's personal taxes and taxes for his company, K. Durant Enterprises, from 2007 to 2011. The lawsuit says Durant will now have to amend his taxes, pay back taxes and possibly penalties.

Durant is seeking a total of $600,000 on three separate counts.

Attorneys for Durant and Elliott didn't immediately return messages.
