Mr Bryan, a former adviser to Bill Clinton who helped raise funds for Mr Obama's re-election campaign, has owed the money to the Internal Revenue Service (IRS) since 2006, according to court filings obtained by The Daily Telegraph from Texas.
Mr Bryan, who has been in a relationship with Ms Wintour since 1999, was also pursued for outstanding Texas property taxes, and has had energy companies he owns in the state chided by local authorities for falling behind on their financial filings.
The findings may threaten Ms Wintour's confirmation as a US ambassador if nominated by Mr Obama. Her appointment would need to be approved by the US Senate, which has in the past objected to irregularities in the tax affairs of nominees and their partners.
Ms. Wintour was one of Mr Obama's leading fundraisers during his re-election campaign, bringing in $500,000 to the president's coffers. At one $35,000-a-plate fundraising dinner in August, Mr Obama thanked "Anna and Shelby for being such extraordinary hosts".
While helping to add to Mr Obama's $1 billion re-election fund, however, Mr Bryan had a significant debt to the US government. A lien filed in Texas shows that he owed more than $1.6 million in March 2006. He has since paid back about $400,000.
