My job did not include the last pay period of the year on my 2009 W2's. On 4/15/10 they brought this to my attention. They suggested that the new book keeper would amend my tax files free of charge. My husband & I wanted to have them amended by our tax preparer , however there price is $150 . We just don’t feel comfortable having anyone else doing my taxes .. Now they are suggesting that I would have to pay for the amendment if I want to go outside of there book keeper. Because it was my employers mistake on the w2's, who is leagally responsible for what portion of charges & penalties if any ?
