gst retrun

As You are Registered in GST even though your Turnover is less then 20 lac , you are liable to file returns,.. so file your return with interest & penalty

Dear sir, you are liable to file returns as per the GST law after availing GST registration.

If taxpayers do not file their returns within a specified due dates mentioned,they are obliged to pay a late fee of Rs. 50/day i.e. Rs. 25 per day in each case of CGST and SGST (in case of any tax liability) and Rs. 20/day i.e. Rs. 10/- day in each CGST and SGST (in case of Nil tax liability) subject to a maximum of Rs. 10,000/-(both acts) , from the given due date to the actual date when the returns are finally filed.
Anyway you can file returns till sep 17 as the late fee is waived off from July 17 to sep 17

note: also check the status of your registration whether is cancelled or not becuase get officials can also cancel the registration due to non filing of returns for a long period.

you are registered in GST portals then you liable for gst return so you filled your gst return earlier bcoz penalty is daily upgrade as late fee.

if you leave Return your Gstin inactive automatically after 6 month. it's new rule of Gst council.
