In response to our letter to Brad Smith, Microsoft PR sent me an email in which they refuse to release the royalty tax data that could vouge for their contention that they did not use their Nevada office to avoid paying more than $1.33 billion in taxes, interest and penalties between 1998 - 2010.
"We won't comment beyond saying that Microsoft pays all due taxes in all jurisdictions in which we operate including our home state of Washington, where the company has a major impact on Washington's economy and generates significant state and local tax revenues." - Microsoft's Jeffrey Reading, Senior PR Manager for Public Policy
The impact of Microsoft's lobbying in 1997, around the time they opened the Nevada office, cut Washington's royalty tax rate from 1.5% to .484%. If you calculate the company's combined savings between tax dodging/avoidance and lobbying, it's somewhere between $4.37 and $6.10 billion dollars.
