text: First of all get a copy of the return, you can do this by filing a form with the IRS? Next write them a letter and camly explain the situation. They are human and make mistakes also find out if they entered a number wrong. I have seen some instances where an employer reported wages on the wrong social and the irs went after the person with this social...did not take long to straighten this out. Patience and time, you will be fine and I am sure if you friend obeys all the tax laws on the initial return there is no way that he/she should owe all of that money unless he has a major profit, capital gains, or stocks sold things of this manor! Let me know how it goes?
