I am transporting goods only for a registered consignor party, & such party is liable to pay GST under RCM.

But still I am registered under GST, because such consignor party required by GSTIN number.

Now, my query is -

1) Do I need to file GST Return?
2) If yes, then can I file a NIL Return with all Zero figures i.e. as was filed under service tax rules?
3) If I need to file GST return with some details then please let me know?
4) Also, my son does a transport commission agent business with a turnover of less than Rs. 20 Lakhs, & he is also registered with GST, so whether he has to file GST return?, & if yes, then who shall be liable to pay GST in his case?

Thanks in Advance...

I Hope there will be someone who will be able to reply my query...plz reply..
