Form NC478G NC Preparers

[Terry D EA]

I have a client who installed a Geo Thermal renewable energy heating system in his home. This qualifies for 30% Federal deducation and 35% NC Deduction. I am using TaxSlayer Pro and the 5695 form has not been released yet. No problem. However, the support folks (guys on duty after regualr hours) can't find the NC 478G form that is used to claim this credit. Also, their unput on the 478 form is kind of lame as well. Here is my question, does anyone know if the NC 478G form should be filed with the return? Personally I would think so as the information should flow from the NC 478G to form 478 and from there to the NC D400 page 2. If this is not able to be done, would you fill the forms out manually and mail the return in? I don't see anyway to attach a .pdf to a return through TaxSlayer Pro. Or, the other option as the support agent told me, put the information on form NC 478 which is only one line and that line is for credits limited to 50% of the tax liability. The credit we are claiming is under the 50% limit but I am not sure if that limit applies to this type of energy credit. Right now, just too tired to look. What would you do here? Contact the NCDOR and ask them?
