The IRS headquarters building was closed in June 2006 as a result of heavy flooding. According to a July 12, 2006 letter from Senator Max Baucus (Dem.-Montana), a ranking member of the U.S. Senate Finance Committee, the sub-basement of the building was filled with water to a depth of twenty feet, and electrical and maintenance equipment in the sub-basement was about 95% damaged or destroyed. The IRS and the General Services Administration announced that the building would remain closed through late 2006. The employees who worked in the building – numbering over two thousand – had been temporarily transferred to other offices at 15 other buildings in the Washington, D.C. area. Computerworld reported that some IRS employees were also allowed to telecommute while the building was closed.
