My California 565 Efile is being rejected, saying that the SOS Filing Number is invalid.  I've been preparing this return since the early 2000's and I have always input the number with 12 zeros - there is NOT requirement for a CA general partnership to register with the CA Secretary of State - at least it was not a requirement in past years.

Did I miss something? Are CA general partnerships now required to register with the CA SOS?

I know I could just have it paperfiled, but that seems silly.  I tried inputting the 0's like in past years and then disabling the error check but that did not work.

Any help is very much appreciated.
