GGRNY,
I agree with what the others have said. I suspect that the payroll department of the company did not set up an employer account with Georgia, and therefore reported all the employee wages on their California tax return. (Just FYI - the Franchise Tax Board collects income taxes, the Employment Development Department collects payroll taxes, just in case you need to ever call again). I think the employer really screwed this up, and the way to fix it is for the employer to amend their DE9 (which is the CA equivalent of the 941).
If I am correct, and the employer will not amend the DE9, your nightmare is just beginning. The FTB will have a record of wages earned from the employer DE9. They are going to want a tax return. If you don't file it, they will assess and collect via any means possible. If you do send in a return and it does not match the wages reported on the DE9, you will get a letter and a demand for payment of taxes. If you send them a letter in response, it will not be read. If you want to file a power of attorney to represent, you have to sign up with the state for access to the website, and then it takes a minimum of 30 days for the FTB to approve your POA. Then you get to make the phone call that will probably not be answered. And if you are so lucky as to get through to a live person, they will not be helpful or courteous. They will start by asking for bank account information on your client.
Your client needs to get with the payroll department and get this fixed before the end of the year.
Sorry to be the bearer of grim news. I have lived and practiced in this state for too long to expect this will come out well for your client.
