Everson's nomination to the five-year term as IRS commissioner now goes to the full Senate for approval.

Everson testified last month that he would pursue tax evaders, including the companies that market tax scams and tax avoidance schemes. He also promised to continue technology upgrades and reorganization plans begun by his predecessor.

Everson is a top manager at the White House Office of Management and Budget. During former President Reagan's administration, he worked in the Immigration and Naturalization Service, the Justice Department and the U.S. Information Agency.
