Am I a candidate for a tax attorney?

An attorney, CPA or IRS Enrolled Agent can all do this. However, you need someone who does this kind of work specifically. There is a vast difference in the experience levels of parties who claim to be able to accomplish what you need done, although most of them will claim to be experts. Ask how many settlements have you done in the last 12 months. Additionally, you may or may not be eligible to settle. It depends on your financial situation and this is another catagory where experience counts. Ask whomever you hire how many times they have done a financial evaluation on a client.
