Federal nominees are required to disclose their wealth in wide ranges, causing the broad estimate for Koskinen’s net worth.
He also reported hundreds of thousands of dollars in retirement accounts, and at least $1 million in a money market account.
Koskinen, a former Freddie Mac executive, told Treasury in his letter that he would step down from unpaid board positions at Soccer 94 and the Duke University Athletics Leadership Board.
Senate Finance aides have said they are still sifting through Koskinen’s nomination paperwork, which they only received in late August. Finance Chairman Max Baucus (D-Mont.) has yet to schedule a nomination hearing for the nominee.
Danny Werfel has been acting as the interim chief at the IRS since May, shortly after the agency disclosed that it singled out Tea Party groups seeking tax-exempt status.
House Majority Leader Eric Cantor (R-Va.) made clear last week that the GOP would continue to make the investigation into the IRS a priority in the weeks to come.
Bloomberg first reported Koskinen's net worth.
