( CNN ) -- Wealthy socialite and Grammy-nominated songwriter Denise Rich has renounced her U.S. citizenship and resides in London , her spokeswoman Judy Smith said Tuesday . Rich 's maiden name , Eisenberg , appeared on April 30 in the Federal Registrar 's Quarterly Publication of Individuals Who Have Chosen To Expatriate , though she left in November 2011 . By handing in her American passport , tax lawyers say she is able to legally avoid paying significant taxes on her estate . Rich , 68 , is the ex-wife of billionaire commodities trader Marc Rich , who was pardoned in 2001 by then-president Bill Clinton for oil profiteering and tax evasion after he fled to Switzerland . The pardon was considered controversial because of Denise Rich 's financial contributions to the Democratic Party and to the Clinton Library . As of 2001 , Denise Rich had made more than $ 1.3 million in political contributions to the Democratic Party since 1993 , including $ 70,000 to Hillary Clinton 's Senate campaign and $ 450,000 to the Clinton presidential library in Arkansas . Investigators told CNN at the time that there were Secret Service logs showing that Rich went to the White House the last night of Bill Clinton 's presidency . Superman renounces his American citizenship . Rich is n't the only high-profile American to abandon ship . Facebook co-founder Eduardo Saverin also appears on this list . He renounced his citizenship in May shortly before Facebook 's initial public offering . They are two of many who have expatriated from the United States in the last few years . `` It may not be coincidental that some of these high profile expatriations are occurring when asset values have been relatively depressed , '' said tax attorney Dean Berry of Cadwalader , Wickersham , & Taft LLP . But Rich is not completely off the tax hook . According to expatriation tax legislation passed in June 2008 , she is considered a covered expatriate and will therefore have to pay an exit tax on the net gain calculations of her assets . It is still far less than she would have paid as a U.S. citizen with a large estate , however , according to tax attorneys . `` Expatriation makes the most sense when asset values are historically low and tax rates are historically low . Her timing may have had something to do with that , '' tax attorney David S. Miller of Cadwalader , Wickersham , & Taft LLP said . In January , Rich put her Fifth Avenue Manhattan penthouse on the market , according to her real estate agency , Corcoran . The property , which boasts 20 rooms and 11 baths , is on sale for $ 65 million . According to her spokeswoman , Rich renounced her citizenship because she wanted to live in London , where her long-time partner and her two daughters live . Rich , a songwriter , has been nominated for Grammys three times . She has written for Patti LaBelle , Chaka Khan and Marc Anthony , among others . In 1999 , Rich was nominated for a Grammy for the duet she penned for Mary J. Blige and Aretha Franklin , titled `` Do n't Waste Your Time . '' When one passport is n't enough .
