You can e-file the D-30 and the D-65. The issue with E-filing the D-30 is that you will need to be registered in DC by completing the FR-500 which allows DC to know your EIN and to give credit for any taxes paid. The D-65 does not need an FR-500 on file since it is only an information return.
This whole issue was started because the DC State Return for Partnerships would not allow me to choose the D-65 without an error. I have never seen that error in the past for the same client I have been helping over the past eight years.
