During a random audit, the employer was asked to provide plan information for 2010, 2011 and 2012. Anomolies turned up and the employer knows that they have to be corrected, including any additional contributions, earnings and penalties. Then the IRS said that they would like information going back to 2006 -- 7 years ago. I thought that 6 years was the limit, unless they can make a case for fraud. Is the 6 year limit just a guideline that doesn't really mean much?
