26 July 2017 I had applied for GST Registration and have received REG-06 (As a composition dealer). As I was not earlier registered under VAT Act or other Acts due to non-taxability of items I dealt in.
I want to confirm the following points:-

1. In which form STOCK INTIMATION is to be filed?
2. Stock upto which date is to be given & by which date? (I have applied on voluntary basis as on 20-July-2017 & received cert. today i.e 26-07-2017)
3. What are the other FORMS that I need to file as a composition dealer?
Please guide.
