I have no problem with that. He can see as many tax professionals as he wants for as many opinions as he wants. But, if he is looking for help to sue his tax agent (which is what ajayagupta asked about in his original post), he will want to seek out the help of an attorney in his area.
I agree, but I have seen people sue tax professionals only to end up looking like fools in court. The classic situation is that they were missing a tax document when they went to do their taxes, and therefore something significant was missing on their original tax return, causing them to owe additional tax plus penalties and interest.
The classic client reaction to such a thing is that "I went to a tax professional because I do not know anything about taxes so its your fault and you have to either make it go away or pay for it since its your fault" (whether it was or wasn't the tax professionals fault).
Sometimes we can make it go away (if it was something that should not have resulted in additional tax). Sometimes we cannot make it go away but we can legitimately mitigate it. Sometimes we cannot make it go away but if the error was our fault we cover the penalties and sometimes interest. Sometimes we cannot make it go away and the taxpayer has to pay the interest and penalty because it was not our fault. On rare occasions the IRS digs their heels in on something and they are wrong...and that is the kind of case that should end up in tax court.
I suspect that the OP's situation is NOT the kind of case that should end up in tax court. I suspect its the kind of case where the enrolled agent has told him that its gone as far as it can legitimately go, but that the OP is free to spend money on a tax attorney to see if it can be taken any further. From what the OP said it appears that the OP believes that the enrolled agent should spend the money on a tax attorney to represent the OP.
Before this OP throws potentially good money after bad, he needs to consult another tax professional or two to make sure that he actually has a case on the tax issue itself. If he does not there is nothing to sue the enrolled agent about.
