Can a CPA represent a client in court, e.g. tax court?. Does a CPA have any confidentiality, i.e. right of privileged communication, with a client as a lawyer has?. I heard Congress was considering giving this privilege some years back in a tax reform bill?

Yes, attorney, CPA and EA can represent client in a tax court.

And, yes, CPAs and enrolled agents DO have a degree of confidentiality that clients and lawyers have always shared.

But it is NOT as comprehensive as lawyer-client privilege.
