As you can imagine, your taxes aren't quite the same as Bill Gate's taxes. According to a report I
found here, Gates says:"My tax return in the United States has to be kept on a special computer because their normal computers can't deal with the numbers," Gates told a Microsoft conference in Lisbon, according to a report from Agence France-Presse. "So I am constantly getting these notices telling me I haven't paid something when really it is just on the wrong computer. Then they will send me another notice telling me how bad they feel that they sent me a notice that was a mistake."
Nice to know that the IRS doesn't discriminate when it comes to causing people headaches with their taxes...
