Thanks for the positive rating. You have a very valid point, but the CA states
that the exempt preparer
would include an enrolled agent and not a registered tax
requires anyone who prepares tax returns
for a fee and is not an exempt preparer to register as a tax preparer with the California Tax Education Council (CTEC). Exempt preparers are California certified public accountants (CPAs), enrolled agents (EAs), attorneys who are members of the State Bar of California, and certain specified banking or trust officials.
I'm assuming you have the PTIN because you are an registered tax preparer with the IRS and not an enrolled agent. If you were an EA, then this wouldn't be a problem.
Both enrolled agents and RTRPs have the right to prepare and sign any tax forms. But the representation rights of enrolled agents before the IRS are generally unlimited whereas the representation rights of RTRPs are limited. RTRPs are limited to representing clients before an Examination function of the IRS when the RTRP prepared the return under examination.
There might be some CA loophole that I'm not aware of. In the link below is the contact info with phone number. It might be best to give them a call.
