Sir/Mam,
If a person has been doing from 2013 and there was no liability to register under any previous tax regime. But now the person wants to get registeration under gst on voluntary basis.
Can he enter the date in 'date of commencement of business' in gst registration form as 1.4.2018 as the business in the past period was minimal?

We are getting duty drawback on account of exports made by us. I have heard that those who are getting credit of duty drawback against export sales, are not at all entitled for any sort of GST Claim Refund.

is it not injustice to claim both interest on late payment of tax and late fee for filing returns?
because both tax payment & return filing are inter connected. without making tax payment we are not allowed filing the return. Most of the trade are ready to file return in time but make delayed payment due to paucity of funds.

If there is machinery which is under process as on 31/03/2018 and not installed in plant although Different parts of machinery has been received and the bill has been received for the same.
