The taxman cometh to YahooSalim Ismail's incompetence as a manager may have brought the wrath of the IRS down on Yahoo. One of his employees at Brickhouse, Yahoo's San Francisco incubator, has moved abroad while being classified, for tax purposes, as "working at home." There are a number of steps companies ought to take when employing a U.S. citizen living abroad, but Ismail apparently skipped them. Now, one of the employee's coworkers has received a summons from the IRS's Criminal Investigation Division, where are investigators are looking into a case of tax fraud. While any penalties Yahoo might pay are small in comparison to the Web giant's bottom line, they'd certainly speak to the sloppy management that's been given a pass at Yahoo for far too long.
