WASHINGTON ( CNN ) -- Members of the Senate Finance Committee met Tuesday with treasury secretary nominee Tim Geithner over concerns involving his personal taxes and the immigration status of a former housekeeper , transition officials said . Timothy Geithner has been nominated for the post of treasury secretary in the Obama administration . The Geithners employed a housekeeper whose employment authorization document expired about three months before she stopped working for them in October 2005 , according to a written statement from the Senate Finance Committee . Later , the housekeeper , who is married to a U.S. citizen , was granted a green card , transition officials said . The second concern involves Geithner 's taxes while he worked for the International Monetary Fund ( IMF ) . According to a statement released by the committee , Geithner failed to pay self-employment taxes while the IMF paid him from 2001 to 2004 . In 2006 , the Internal Revenue Service audited Geithner for tax years 2003 and 2004 , and he paid $ 16,732 for the taxes and interest for those years , the statement said . After Obama nominated him for treasury secretary , Geithner voluntarily amended his taxes for 2001 and 2002 , paying $ 25,970 for those taxes and interest , the committee said . The presidential transition team told Finance Committee staff about Geithner 's taxes early last month , the committee said . As an international organization , the IMF does not withhold money from employees ' paychecks to pay Social Security and Medicare . U.S. employees are required to pay them on their own . Robert Gibbs , the incoming White House spokesman , called Geithner 's tax issue a `` common mistake . '' `` The president-elect chose Tim Geithner to be his treasury secretary because he 's the right person to help lead our economic recovery during these challenging times , '' Gibbs said in a written statement . `` He 's dedicated his career to our country and served with honor , intelligence and distinction . That service should not be tarnished by honest mistakes , which , upon learning of them , he quickly addressed . '' The Finance Committee said it would continue to review Geithner 's tax returns and other information ahead of a nomination hearing . `` When errors or issues of concern are discovered , transparency is vital to allow members of the committee and the entire Senate to fully review and assess the relevant information before hearings and votes occur , '' the committee said . `` I believe that these errors , although serious , do not rise to the level of disqualification . He is an extremely competent man , '' said committee Chairman Max Baucus , D-Montana . `` The errors were , in my judgment , honest mistakes . He did not in any way intentionally make those mistakes . '' Sen. Charles Schumer , D-New York , also said the mistakes were `` not at all disqualifying . '' `` Tim came to the committee , admitted he had made some mistakes , and was very contrite , '' he said . `` I continue to strongly support his nomination and given the tough economic conditions , hope we can confirm him as quickly as possible . ''
