microsoft: Microsoft says US has asked for $28.9 billion in audit dispute
Microsoft said the IRS notices relate to an ongoing dispute between the company and the U.S. tax authority, which is auditing how Microsoft allocated its profit among different countries and jurisdictions. The Redmond, Washington-based company said it has since changed its practices so that "issues raised by the IRS are relevant to the past but not to our current practices," according to a Microsoft blog.
