Microsoft escalates dispute with US tax agency

Washington

MICROSOFT Corp and the IRS (Internal Revenue Service) are back in court, this time fighting about the US tax agency's interest in hiring David Boies, the lawyer who beat Microsoft in an antitrust case in 2000.

The software company filed a federal lawsuit on May 29 in Seattle, marking the latest legal flurry over an ongoing IRS audit. At issue are "tens of billions of dollars" in corporate income, according to the IRS.
